As rates of obesity continue to rise, so does the impact of obesity on cognitive function. Engaging in physical activity is one pathway through which individuals can help maintain cognitive function. This study examined whether any link between exercise and cognitive function was associated with weight characteristics. Data from 6,012 participants in the Health and Retirement Study were used. The association between participation in light or moderate physical activity and better cognitive function was particularly strong for overweight or obese adults and less so for those who were normal weight. Overall, the findings suggested that while being physically active is associated with better cognitive function regardless of weight, the associations were stronger for individuals who were overweight/obese compared with those who were normal weight. Given the results were particularly pronounced for waist circumference (relative to body mass index), further research should be conducted to examine if individuals with greater abdominal adiposity may benefit most from staying active in terms of their cognitive function.

Context: The purpose of the study was to develop normative ranges and standards for knee and shoulder isokinetic and anthropometric values. These standards can be qualitatively interpreted and allow practitioners to classify isokinetic and anthropometric values more objectively for university-level netball players. Design: Posttest only observational study design. All players were only evaluated once during the in-season to generate normative ranges. Methods: A total of 51 female players volunteered. Participants were evaluated on an isokinetic dynamometer at 60° per second to obtain knee-extensor and knee-flexor values as well as shoulder-flexor and shoulder-extensor values. A total of 16 anthropometric variables were collected including stature, body mass, 8 skinfolds, and 6 circumferences. Between-group differences were calculated to determine whether playing level was a differentiating factor in data. Results: Normative standards were developed for isokinetic parameters associated with the knee and shoulder joints as well as skinfolds and circumference measures. No statistically significant between-group differences were evident (χKruskal-Wallis²[2] = 3.96, P = .140). Conclusion: These standards can be used by coaches and practitioners to set attainable goals for individual players or those from secondary leagues, classify individual and team-based performances, and facilitate decision-making processes.

Food insecurity is highly prevalent and linked to poorer diet and worse metabolic outcomes. Food insecurity can be stressful, and could elicit chronic psychological and physiological stress. In this study, we tested whether stress could be used to identify those at highest risk for worse diet and metabolic measures from food insecurity. Specifically, we hypothesized that cortisol (a physiological marker of stress) and perceived psychological stress would amplify the link between food insecurity and hyperpalatable food intake as well as metabolic measures. In a sample of 624 Black and White women aged 36-43 who participated in the NHLBI Growth and Health Study's midlife assessment, we assessed associations between food insecurity with hyperpalatable food intake (high fat + high sodium foods; high fat + high sugar foods; and high carbohydrate + high sodium foods), and metabolic measures (fasting glucose, insulin resistance, and waist circumference). We found that food insecurity was associated with higher levels of perceived stress (R2 = 0.09), and greater intake of high fat + high sugar (hyperpalatable) foods (R2 = 0.03). In those with higher cumulative cortisol (as indexed by hair cortisol), food insecurity was associated with higher levels of fasting glucose. Neither cortisol nor perceived stress moderated any other relationships, and neither variable functioned as a mediator in sensitivity analyses. Given these largely null findings, further research is needed to understand the role stress plays in the chronic health burdens of food insecurity.

Objectives: Movement behaviors and abdominal obesity are associated with higher inflammatory biomarkers. However, the role of waist circumference as a mediating factor is still unknown. Thus, our aims were to (1) test the associations between 24-hour movement behavior variables (physical activity, sedentary behavior, and sleep), abdominal obesity, and pro- and anti-inflammatory biomarkers; and (2) investigate whether abdominal obesity had a mediating effect between the investigated associations. Methods: This multicenter cross-sectional study included 3591 adolescents (aged 12–17 y) from 4 Brazilian cities. Waist circumference (in centimeters; at half the distance between the iliac crest and at the lower costal margin), 24-hour movement behaviors (validated questionnaire), high-sensitive C-reactive protein, and adiponectin (serum plasma) were evaluated. We used multiple mediation regression models (95% confidence interval) to determine if waist circumference mediated the association between 24-hour movement behaviors and pro- and anti-inflammatory biomarkers. Results: The results revealed that screen time and moderate to vigorous physical activity were not associated with pro- or anti-inflammatory biomarkers. However, sleep duration (in hours per day) was negatively associated with pro- (C-reactive protein, β = −0.08; 95% confidence interval, −0.38 to −0.02) and anti- (adiponectin, β = −0.31; 95% confidence interval, −2.13 to −0.12) inflammatory biomarkers. Our results also showed that waist circumference mediated the association between sleep duration and high-sensitive C-reactive protein (2.7%), and adiponectin (2.8%). Conclusion: Sleep duration was inversely associated with pro- and anti-inflammatory biomarkers, and these relations were mediated by abdominal obesity. Therefore, adolescents having healthy sleep can have implications for reducing waist circumference and inflammatory indicators. [ABSTRACT FROM AUTHOR]

Introduction: Excessive abdominal adiposity represents a cardiovascular disease risk factor. Waist circumference (WC) reflects abdominal adiposity and is known as an easy-to-measure indicator of obesity. This study aimed to evaluate the relationship between WC level and the development of cerebral infarction in Koreans. Methods: 209,442 Koreans were included among the general population registered in the National Health Information Database. Depending on the degree of WC, the possibility of cerebral infarction was tracked for 4.37 personyears. Identification of patients with cerebral infarction was confirmed through the diagnostic code ICD I63 of inpatient or outpatient. Participants' data were analyzed by sex. The hazard ratios (HRs) and confidence interval (CI) for cerebral infarction were calculated using the Cox proportional hazards model. Results and discussion: Between 2009 and 2013, 2,403 cases (1.15%) of cerebral infarction occurred during the follow-up period of 915,223.6 person-years. The HRs (95% CI) for incident cerebral infarction in men was adjusted for multiple covariates, and comparison of WC levels second, third, and fourth quartile with the first quartile showed 1.10 (0.94-1.28), 1.11 (0.95-1.30), and 1.24 (1.07-1.45), respectively (P for trend 0.045). This association was not significant in women (P for trend 0.619). The severity of WC levels in men is significantly associated with the risk of developing cerebral infarction in Koreans. This finding indicates that other measurements for excessive adipose visceral tissue, except abdominal circumference, need to be taken into account to identify the risk of cerebral infarction in women.

In this triple-blind, randomized clinical trial, 60 menopausal women between the ages of 45 and 65 were randomized to receive 78% dark chocolate (12 g/day) or milk chocolate (12 g/day) for eight weeks. The primary outcome was depression scores. Secondary outcomes included sleep quality and anthropometric indices. ANCOVA with baseline adjustment showed that the mean depression score after the intervention in the group receiving dark chocolate was significantly reduced compared to the milk chocolate group (mean difference: -2.3; 95% confidence interval: -3.9 to -0.8; p = 0.003; Cohen's d = -0.54). However, no statistically significant difference in the overall sleep quality score and its subdomains was observed between the two groups after the intervention (p > 0.05). Furthermore, after the intervention, there was no statistically significant difference between the two groups in terms of anthropometric indices, including weight (p = 0.075), BMI (p = 0.137), waist circumference (p = 0.463), and hip circumference (p = 0.114). The study suggests that consuming 78% dark chocolate for eight weeks may contribute to improvements in depression scores, but it does not appear to improve sleep quality or anthropometric indices.

ABSTRACT Objective Methods Results Conclusions We aim (1) to examine secular trends in height, weight, and waist circumference (WC) among Peruvian children and adolescents living in the city of Junín and (2) to compare their growth status with the World Health Organization (WHO) and US Centers for Disease Control and Prevention (CDC) reference data.The sample included 2874 Peruvians (n = 1681 in the 2009 cohort and n = 1193 in the 2019 cohort) aged 6–16 years from the district of Junín (4107 m of altitude). Height, weight, and WC were measured using standardized protocols. Within each sex, a two‐way between‐subjects analysis of variance—age, and cohort as main factors and age‐by‐cohort as the interaction—was used to test for differences in height, weight, and WC. STATA 17 software was used in all statistical analyses.Height revealed a positive secular trend among girls, aged 6–11 years, and among boys up to 14 years of age. Similar positive secular trends in weight and WC were found across all age groups in both boys and girls. Compared to North American peers, children in the 2009 cohort were shorter, lighter, and had a smaller WC. For weight and WC, the 2019 cohort overlapped the 50th percentile across all age groups (except for 16‐year‐old girls).Both boys' and girls' height, weight, and WC showed positive secular trends between 2009 and 2019, with statistically significant differences varying across age groups. Peruvian youth of both sexes were shorter and lighter than their North American peers. [ABSTRACT FROM AUTHOR]

Background: The association between weight-adjusted waist index (WWI) and disability is unclear. This study aimed to assess the relationship between WWI and disability in middle-aged and elderly Chinese individuals and provide more predictive indicators for disability prevention. Methods: In this study, 13,015 middle-aged and older adults aged 45 years and above who were surveyed in 2011 by the China Health and Aging Tracking Survey (CHARLS) database were selected, and 8344 respondents with complete data were included for cohort analysis after seven years of follow-up. Information on clinical demographic characteristics, anthropometric indices, assessment of disability, and related covariates were collected, and the presence or absence of disability was assessed by the disability scale. WWI was calculated by dividing the waist circumference (cm) by the square root of the body weight (kg). Cox proportional hazards model was used to analyze the association between WWI and disability after follow-up. Results: Our study found that 2912 of 8344 participants had disability after seven years of follow-up, and disability incidence was approximately 34.9%. Age, sex, place of residence, chronic disease, depression, waist circumference, and WWI were significantly associated with disability in univariate analysis. Among them, there was a positive association between WWI as a continuous variable and incidence of disability (hazard ratio (HR) = 1.26, 95% CI: 1.22–1.31, p < 0.001). WWI was transformed into categorical variables using quartiles as cutoffs for disability regression analysis. After adjusting covariates, HR values in the 2nd, 3rd and 4th quantile showed an increasing trend compared with the 1st quantile, and the risk of disability among WWI subjects in the 4th quantile increased by 43% (95% CI: 1.24–1.64). P values for the trend test in the model were all < 0.001. In subgroup analyses, the positive association between WWI and risk of disability remained robust for sex, age, alcohol consumption, smoking status, education level, marital status, and place of residence after adjusting for all covariates considered in this study. Conclusions: WWI is a new and reliable obesity-related indicator that can be used for disability prevention. WWI can be detected and controlled for reducing the risk of disability.

Background: The presence of hypertension significantly increases the risk of diabetes, particularly type 2 diabetes. Recently, Visceral Adiposity Index (VAI) has been introduced as a straightforward and robust alternative indicator for early detection of metabolic syndrome, cardiovascular disease, and T2DM. Visceral adiposity, more dangerous than subcutaneous fat, is associated with metabolic syndrome and cardiovascular diseases. The VAI and Lipid Accumulation Product (LAP) are indices that quantify visceral fat and lipid overaccumulation, respectively. This study aims to explore the association between VAI, LAP, and type 2 diabetes mellitus (T2DM) in US adults with hypertension using NHANES data from 2005 to 2018. Methods: We analyzed data from 5,620 participants with hypertension in The National Health and Nutrition Examination Survey (NHANES). VAI and LAP were calculated using established formulas. The VAI is calculated based on a combination of waist circumference, body mass index (BMI), triglycerides, and high-density lipoprotein (HDL) cholesterol levels. Logistic regression models were applied to evaluate the association between these indices and T2DM, adjusting for potential confounders. Subgroup analyses by age and gender were also conducted to assess variations in risk. Results: In all, 5,620 participants were enrolled in our analysis, with 2,754 (49%) being female, and a mean (standard deviation, SD) age of 57 (15) years. The mean (SD) cumulative average VAI and LAP among all participants was 241 (2.71) and 75 (67), respectively. Totally, higher VAI and LAP indices were significantly associated with an increased risk of T2DM in individuals with hypertension. For VAI, the odds ratios (OR) for T2DM were higher in older adults (≥ 60 years) [95% confidence interval (CI): 1.37, 1.22–1.53, per 1 SD increase] and females [95% confidence interval (CI): 1.39, 1.27–1.52, per 1 SD increase], indicating age and gender differences in risk. Non-linear relationships were observed, suggesting thresholds beyond which the risk of T2DM escalates dramatically. Conclusions: Both VAI and LAP are reliable markers for assessing T2DM risk in individuals with hypertension. Incorporating these indices into clinical practice could enhance the identification of high-risk individuals and facilitate early intervention strategies. Future longitudinal studies are needed to confirm these associations and explore targeted interventions. [ABSTRACT FROM AUTHOR]

Background: Antipsychotic drugs may have adverse effects on the components of metabolic syndrome. Previous studies have shown that changes in the intestinal microbiome are associated with metabolic disturbances in patients with schizophrenia. The objective of this study was to determine the effects of synbiotics on the components of metabolic syndrome as primary outcomes in patients with schizophrenia. Secondary outcomes were HbA1c, insulin resistance, LDL-c, and anthropometric measurements. Methods: In this double-blind, placebo-controlled trial, seventy patients with schizophrenia receiving antipsychotic drugs who had at least two criteria of metabolic syndrome were randomly divided into two groups to receive either two capsules of a synbiotic supplement or a placebo daily for 8 weeks. Anthropometric indices and biochemical parameters were measured at baseline and after the intervention. Results: Fifty-five patients completed the study. The synbiotic supplement significantly decreased waist circumference and HbA1C compared to placebo (-2.66 ± 4.20 vs. 3.03 ± 4.50 and − 0.26 ± 0.54 vs. 0.20 ± 0.75, respectively). Although BMI did not change significantly in the synbiotic + antipsychotic group, it increased in the placebo + antipsychotic group (-0.37 ± 1.00 vs. 0.61 ± 1.09 P < 0.5). LDL-c and triglyceride (TG) levels decreased significantly in the synbiotic + antipsychotic group, but the change was not significantly different from that of the placebo + antipsychotic group. FBS, HDL-c, systolic and diastolic blood pressure, insulin resistance, and total cholesterol were not significantly different between the two groups after intervention. Conclusion: Synbiotic supplement may decrease waist circumference, HbA1c, LDL and TG and prevent BMI increase in patients receiving antipsychotic drugs.

Summary People with COVID‐19 infection continue to have their symptoms or develop new ones after recovery. This is called long‐COVID syndrome. We aimed to examine the association of general and abdominal obesity with long COVID. This study was conducted using Isfahan COVID Cohort (ICC). Totally 4008 including 3213 hospitalized and 795 non‐hospitalized patients with positive RT‐PCR were included. Body mass index (BMI) and waist circumference (WC) were calculated. BMI >25 kg/m2 and WC >88 cm in women and 102 cm in men were considered generally and abdominally obese, respectively. By using an open‐ended questionnaire, subjects were asked whether they had any new or persistent symptom. Reported symptoms were categorized in three different fields including general, cardiac, and respiratory symptoms. Higher BMI and WC tended to increase general symptoms (odds ratio [OR] for BMI = 1.16, 95 % confidence interval (95% CI): 0.97, 1.38, and OR for WC = 1.14, 95% CI: 0.99, 1.32). Higher BMI significantly increased cardiovascular (OR = 1.38, 95% CI: 1.14, 1.67) and respiratory symptoms (OR = 1.43, 95% CI: 1.15, 1.78). Compared with patients with normal WC, the risk of cardiovascular (OR = 1.44, 95% CI: 1.24, 1.69) and respiratory symptoms was significantly higher in subjects with abdominal obesity (OR = 1.31, 95% CI: 1.10, 1.56). We found that general and abdominal obesity were associated with increased risk of cardiovascular and respiratory symptoms in patients with long‐COVID symptoms. However, only general obesity was associated with increased risk of general symptoms. [ABSTRACT FROM AUTHOR]

AbstractThe authors aimed to explore the association between anthropometric indicators and cognitive function and determine which aspects of anthropometric indicators are most closely related to cognitive function. A sum of 3269 older women were included in this study. Body mass index (BMI), waist circumference, hip circumference, calf circumference, and waist-to-hip ratio were obtained to reflect anthropometric indicators. Cognitive function was assessed using Mini-Mental State Examination (MMSE). Researchers revealed statistically significant differences in total MMSE scores among the low, medium, and high groups of BMI, waist circumference, hip circumference, and calf circumference. Researchers also observed that calf circumference, hip circumference, and waist circumference are significantly associated with the total MMSE score. Our findings highlighted that older women with greater BMI, waist circumference, hip circumference, and calf circumference have a better level of cognitive function. Calf circumference is the most closely anthropometric indicator related to cognitive function in Chinese older women. [ABSTRACT FROM AUTHOR]

Background: Numerous single nutrients have been suggested to be linked with leukocyte telomere length (LTL). However, data on nutrient patterns (NPs), particularly in Chinese population, are scarce. This study aimed to examine the relationship between nutrient-based dietary patterns and LTL, and the potential role of metabolic factors. Methods: Dietary data was obtained via 24-hour food recalls, and principal component analysis (PCA) was used to identify NPs. LTL was assessed using a real-time PCR assay. Multiple linear regression was conducted to determine the association between NPs and LTL. The potential role of metabolism among them was analyzed using mediation models. Results: A total of 779 individuals from northern China were included in this cross-sectional analysis. Five main nutrient patterns were identified. Adjusted linear regression showed that the "high sodium" pattern was inversely associated with LTL (B=-0.481(-0.549, -0.413), P < 0.05). The "high vitamin E-fat" pattern exhibited a positive correlation (B = 0.099(0.029, 0.170), P < 0.05), whereas the "high vitamin A-vitamin B2" pattern was negatively correlated with LTL (B=-0.120(-0.183, -0.057), P < 0.05), respectively. No significant associations were observed for the remaining nutrient patterns. The mediation model demonstrated that diastolic blood pressure and waist circumference could individually and collectively mediate the negative impact of the "high sodium" pattern on LTL (BDBP=-0.0173(-0.0333, -0.0041), BWC=-0.0075(-0.0186, -0.0004), Bjoint=-0.0033 (-0.0072, -0.0006), all P < 0.05). Moreover, glycosylated hemoglobin and non-high-density lipoprotein cholesterol mediate the relationship between the "high vitamin E-fat" pattern and LTL (BHbA1c=0.0170(0.0010,0.0347), Bnon-HDL-C= 0.0335 (0.0067, 0.0626), all P < 0.05), respectively. Conclusions: The "high sodium" and "high vitamin E-fat" nutrient patterns demonstrated negative and positive associations with LTL and metabolic indicators may play complex mediating roles in these relationships.

Background: This study aimed to assess the longitudinal association between dynapenic abdominal obesity and new-onset arthritis among the middle-aged and older Chinese population. Methods: We included 6863 participants from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study (CHARLS). Dynapenia was defined as handgrip strength < 28 kg for males, and < 18 kg for females. Abdominal obesity was defined as a waist circumference ≥ 90 cm for males and ≥ 85 cm for females. Based on the definitions, all participants were divided into four groups: no dynapenia and no abdominal obesity (ND/NAO), abdominal obesity alone (ND/AO), dynapenia alone (D/NAO), and dynapenia and abdominal obesity (D/AO). The association between dynapenic abdominal obesity and new-onset arthritis was assessed by sex using the Poisson regression models. Results: After a four-year follow-up, 1272 (18.53%) participants reported new-onset arthritis. Those in the D/AO group had a significantly increased risk of new-onset arthritis compared to those in the ND/NAO group (adjusted relative risk (RR): 1.34, 95% confidence interval (CI): 1.01–1.77). In females, the ND/AO (RR: 1.21, 95% CI: 1.03–1.43) and D/AO (RR: 1.39, 95% CI: 1.01–1.93) groups were associated with a higher risk of arthritis. This significant association was not observed in males. Conclusions: Our results indicated that the combined effect of dynapenia and abdominal obesity significantly increased the risk of new-onset arthritis in females, but this association was not observed in males.

(1) Background: This study aims to assess visceral fat values, waist circumference (WC), body mass index (BMI), and body fat percentage for their ability to predict poor outcomes during COVID-19 patients' hospitalization; (2) Methods: This study was a prospective cohort of mild–moderate COVID-19 patients hospitalized at Dr. Cipto Mangunkusumo National General Hospital from December 2020 to March 2021. This study includes hospitalized patients over 18 diagnosed with COVID-19 using RT-PCR. Patients who do not have chest radiography, waist circumference, a bioimpedance analyzer (BIA) error, or are unable to stand or mobilize during the examination are excluded from this study. Cox regression was used for multivariate analysis; (3) Results: The study included two hundred sixty-one patients. The median visceral fat value was 10 (equivalent to 100 cm2), the WC was 93.4 cm, the BMI was 26.1 kg/m2, and the body fat percentage was 31.5%. Based on multivariate Cox regression, WC was statistically significant as an independent factor influencing poor outcomes in COVID-19 patients (RR 1.037 [95% CI 1.011–1.064]) along with COVID-19 degree of severity (RR 3.063 [95% CI 1.537–6.104]) and comorbidities (RR 2.123 [95% CI 1.017–4.435]); (4) Conclusions: Waist circumference can influence poor outcomes in confirmed COVID-19 patients during hospitalization.

Aim: To investigate the relationship and potential causality between biological ageing and periodontitis. Materials and Methods: We obtained the National Health and Nutrition Examination Survey (NHANES) and genome‐wide association study (GWAS) summary statistics as well as single‐cell sequencing data. Multivariate regression analysis based on cross‐sectional data, Mendelian randomization (MR) and multi‐omics integration analysis were employed to explore the causal association and potential molecular mechanisms between biological ageing and periodontitis. Additionally, two‐step MR mediation analysis explored the risk factors in biological ageing‐mediated periodontitis. Results: We analysed data from 3189 participants in the NHANES data and found that higher biological age was associated with increased risk of periodontitis. MR analyses revealed causal associations between biological age measures and periodontitis risk. Frailty (odds ratio [OR] = 2.08, 95% confidence interval [CI]: 1.04–4.18, p =.039) and GrimAge acceleration (OR = 1.16, 95% CI: 1.01–1.32, p =.033) were causally associated with periodontitis risk, and these results were validated in a large‐scale meta‐periodontitis GWAS dataset. Additionally, the risk effects of body mass index, waist circumference and lifetime smoking on periodontitis were partially mediated by frailty and GrimAge acceleration. Conclusions: Evidence from cross‐sectional survey and MR analysis suggests that biological ageing increases the risk of periodontitis. Additionally, improving the associated risk factors can help prevent both ageing and periodontitis. [ABSTRACT FROM AUTHOR]

Objectives: Visceral adipose tissue (VAT) is highly associated with metabolic syndrome (MetS), which is rapidly increasing in young adults. However, accessible VAT measurement methods are limited, restricting the use of VAT in early detection. This cross‐sectional study sought to determine if near‐infrared reactance spectroscopy (NIRS)‐derived VAT (VATNIRS) was associated with MetS in a multi‐ethnic sample of young adults. Methods: A total of 107 male and female (F:62, M:45) participants (age: 23.0 ± 4.3y; BMI: 27.1 ± 6.6 kg/m2) completed measurements of fasting blood pressure, blood glucose (FBG), blood lipids, and anthropometric assessments including waist circumference and VATNIRS. MetS severity (MetSindex) was calculated from the aforementioned risk factors using sex and race‐specific equations. Results: VATNIRS was higher in participants with, and at risk for, MetS compared to those with lower risks (all p <.001). VATNIRS was positively associated with MetSindex for all groups (all p <.001). VATNIRS showed positive associations with systolic (SBP), diastolic (DBP), and mean arterial pressure (MAP), LDL‐C and LDL‐C‐related biomarkers, and FBG; and negative associations with HDL‐C and HDL‐C‐to‐total cholesterol ratio (all p <.050). Associations between VATNIRS and blood pressure for females, and LDL‐C and LDL‐C‐related biomarkers for males, were nonsignificant (all p >.050). VATNIRS was positively associated with DBP in African–American participants, and SBP in White participants, resulting in positive associations with MAP for both groups (all p <.050). Conclusions: VATNIRS is associated with MetS and individual MetS risks factors in a multi‐ethnic sample of young adults; providing a noninvasive, cost‐effective, portable, and accessible method that may assist in the early detection of MetS and other cardiometabolic abnormalities.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and polycystic ovary syndrome (PCOS) share several pathophysiological mechanisms. While the prevalence of MASLD has been extensively studied in PCOS populations, the occurrence of PCOS among female adolescents with transient elastography (TE)-confirmed MASLD in pediatric hepatology settings remains poorly characterized. This cross-sectional study aims to address this knowledge gap and elucidate potential clinical and biochemical differences between female adolescents with MASLD and comorbid PCOS compared to those without PCOS. Methods: The study cohort included 45 female adolescents with TE-diagnosed MASLD. Comparative analyses of clinical and laboratory parameters were performed between those with (n = 19) and those without (n = 26) comorbid PCOS, diagnosed according to the Rotterdam criteria. Results: Adolescents with MASLD and comorbid PCOS exhibited significantly higher weight, lower height, and increased waist circumference compared to those without PCOS. Additionally, the prevalence of acanthosis nigricans was significantly higher in the PCOS group (68.4% versus 34.6%, p = 0.025). Regarding laboratory parameters, serum phosphorus levels and liver enzymes—including aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase—were significantly lower in adolescents with comorbid PCOS. However, no significant differences were observed in lipid profiles, glucose metabolism, or novel non-invasive biomarkers of MASLD. Conclusions: This study reveals distinct clinical and biochemical profiles in female adolescents with MASLD and comorbid PCOS compared to those without PCOS. These findings have the potential to inform and refine future screening protocols and diagnostic algorithms for these interrelated conditions, specifically tailored to pediatric hepatology settings.

Background: Neighborhood poverty is associated with adiposity in women, though longitudinal designs, annually collected residential histories, objectively collected anthropometric measures, and geographically diverse samples of midlife women remain limited. Objective: To investigate whether longitudinal exposure to neighborhood concentrated poverty is associated with differences in body mass index (BMI) and waist circumference (WC) among 2,328 midlife women (age 42–52 years at baseline) from 6 U.S. cities enrolled in the Study of Women's Health Across the Nation (SWAN) from 1996 to 2007. Methods: Residential addresses and adiposity measures were collected at approximately annual intervals from the baseline visit through a 10-year follow-up. We used census poverty data and local spatial statistics to identify hot-spots of high concentrated poverty areas and cold-spots of low concentrated poverty located within each SWAN site region, and used linear mixed-effect models to estimate percentage differences (95% confidence interval [CI]) in average BMI and WC levels between neighborhood concentrated poverty categories. Results: After adjusting for individual-level sociodemographics, health-related factors, and residential mobility, compared to residents of moderate concentrated poverty communities, women living in site-specific hot-spots of high concentrated poverty had 1.5% higher (95% CI: 0.6, 2.3) BMI and 1.3% higher (95% CI: 0.5, 2.0) WC levels, whereas women living in cold-spots of low concentrated poverty had 0.7% lower (95% CI: −1.2, −0.1) BMI and 0.3% lower (95% CI: −0.8, 0.2) WC. Site-stratified results remained in largely similar directions to overall estimates, despite wide CIs and small sample sizes. Conclusions: Longitudinal exposure to neighborhood concentrated poverty is associated with slightly higher BMI and WC among women across midlife. [ABSTRACT FROM AUTHOR]

• Better diet quality had a direct (beneficial) effect on pain. • Higher consumption of core foods was related to less pain in women, but not men. • Adiposity did not mediate the relationship between diet quality and pain. • Strategies for pain management should consider diet quality. Dietary intake has been associated with pain and physical function, but it is unclear if these relationships are mediated by adiposity. Data were derived from the Whyalla Intergenerational Study of Health (n = 654, 57% women). Structural equation modelling tested the hypotheses that adiposity (body mass index (BMI), waist circumference (WC), or body fat (BF, dual energy x-ray absorptiometry)) would mediate the relationship between diet quality (Dietary Guideline Index (DGI) total, core, or non-core scores) and pain (Short Form-36 bodily pain scale (SF36-BPS)), or physical function (grip-strength), overall, and by gender. Adiposity did not mediate a relationship between DGI scores and pain. Direct effects were observed between DGI total scores and SF36-BPS accounting for BMI (β = 0.170, 95% CI 0.002, 0.339), and between DGI core food scores and SF36-BPS (BMI, β = 0.278, 95% CI 0.070, 0.486; WC, β = 0.266, 95% CI 0.058, 0.474; BF, β = 0.266, 95% CI 0.060, 0.473). In women, direct effects existed between DGI scores and SF36-BPS (DGI total scores, BMI, β = 0.388, 95% CI 0.162, 0.613; WC, β = 0.372, 95% CI 0.146, 0.598; BF, β = 0.382, 95% CI 0.158, 0.605, and DGI core scores, BMI, β = 0.482, 95% CI 0.208, 0.757; WC, β = 0.472, 95% CI 0.197, 0.747; BF, β = 0.467, 95% CI 0.195, 0.739), and DGI total scores and grip-strength (BMI, β = 0.075, 95% CI 0.008, 0.142; WC, β = 0.076, 95% CI 0.009, 0.143; BF, β = 0.079, 95% CI 0.011, 0.146). Better diet quality is associated with lower bodily pain, irrespective of adiposity. Findings highlight the potential role of diet quality in pain management and function, particularly in women. A cross-sectional study of 654 Australian adults (57% women) from the WISH found better diet quality, particularly the intake of core foods, assessed via the DGI, was associated with lower body pain. These findings were most pronounced in women. Mediation analyses did not show any influence of adiposity in this relationship.

• People with obesity plus prediabetes or T2DM had elevated metabolic dysregulation. • Those with prediabetes or T2DM had decreased vitamin C status. • This was despite comparable dietary intakes to those without diabetes. • Vitamin C status was inversely associated with metabolic dysregulation. • Thus, metabolic dysregulation is associated with an increased demand for vitamin C. Obesity and diabetes are known to negatively affect vitamin C status. However, whether the presence of diabetes, in addition to obesity, contributes an additional impact on vitamin C status is currently uncertain. In a cohort of 152 adults living with obesity, we assessed metabolic and nutrient parameters in participants without diabetes (n = 92), and with prediabetes (n = 22) and type 2 diabetes mellitus (T2DM; n = 35). Vitamin C concentrations were measured in plasma and leukocytes using HPLC and vitamin C intakes were assessed using 24-hour dietary recall. Metabolic severity scores were derived using gender, ethnicity, height, weight, waist circumference, systolic blood pressure, fasting glucose, HDL, and triglyceride values. In people living with obesity, those with prediabetes and T2DM had increased metabolic dysregulation and decreased vitamin C status relative to those without diabetes (P <.05). Vitamin C deficiency was observed in a high proportion (23%-32%) of participants with prediabetes and T2DM and ≥50% had hypovitaminosis C. However, there was no difference in vitamin C intake between those without diabetes and those with prediabetes or T2DM (P >.05). There was a significant inverse correlation between plasma vitamin C status and metabolic severity score (r = -0.290, P <.001). Linear regression indicated that for every 1-unit increase in metabolic severity score, there was a 6.5 µmol/L decrease in vitamin C status. Thus, the enhanced metabolic dysregulation observed with prediabetes and T2DM is associated with an increased demand for vitamin C in people living with obesity. In people living with obesity, those with prediabetes (orange circles) and type 2 diabetes mellitus (T2DM; red circles) had increased metabolic dysregulation and decreased plasma vitamin C status relative to those without diabetes (green circles). For every 1-unit increase in metabolic severity score, there was a 6.5 µmol/L decrease in plasma vitamin C status. [Display omitted] [ABSTRACT FROM AUTHOR]

Background: Endometriosis is intricately linked to metabolic health. The Cardiometabolic Index (CMI), a novel and readily accessible indicator, is utilized to evaluate metabolic status. This study seeks to investigate the potential correlation between CMI and endometriosis. Methods: Data from four consecutive survey cycles of the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2006 were utilized. This included adult females with self-reported diagnoses of endometriosis and complete information required for calculating the CMI. The calculation formula for CMI is Triglycerides(TG) / High-density lipoprotein cholesterol (HDL-C) × WHtR (WHtR = waist circumference / height). A multivariable logistic regression model was employed to investigate the linear association between CMI and endometriosis. Subgroup analyses were performed to explore potential influencing factors. Additionally, the linear relationship was validated using restricted cubic spline (RCS) curve plotting and threshold effect analysis. Results: This study, based on the National Health and Nutrition Examination Survey (NHANES), included a cohort of 2,224 adult women. The multivariable logistic regression analysis demonstrated that in the fully adjusted model, individuals with the highest CMI exhibited a 78% elevated likelihood of endometriosis compared to those with the lowest CMI (OR = 1.78; 95% CI, 1.02–3.11, P < 0.05). The subgroup analysis indicated that there were no significant interactions between CMI and specific subgroups (all interaction P > 0.05), except for the subgroup stratified by stroke status (P < 0.05). Additionally, the association between CMI and endometriosis was linear, with a 20% increase in the association for each unit increase in CMI when CMI > 0.67 (OR = 1.20; 95% CI, 1.05–1.37, P < 0.01). Conclusion: The study found that CMI levels are closely correlated with endometriosis, with this correlation increasing when the CMI exceeds 0.67. This finding implies that by regularly monitoring CMI levels, physicians may be able to screen women at risk for endometriosis at an earlier stage, thereby enabling the implementation of early interventions to slow the progression of the disease. To further validate these findings, larger-scale cohort studies are required to support the results of this research. [ABSTRACT FROM AUTHOR]

Aim: To assess the prevalence of non‐communicable disease risk factors among the nursing staff and educate them on prevention. Background: Nursing staff is integral to the Indian community healthcare systems. Recent studies report a high prevalence of non‐communicable diseases in Indian nursing staff. Therefore, data on the prevalence of non‐communicable disease risk factors among nursing staff are crucial for education on prevention. Design: A cross‐sectional digital survey‐based study. Method: We invited 4435 nursing staff to attend our online survey. We used a customized questionnaire for data collection, including a digitized version of the Community‐Based Assessment Checklist form. A score of >4 was considered high risk and warranted screening. Result: Among 682 nursing staff who attended, 70% had never undergone screening for non‐communicable diseases. The prevalence of non‐communicable disease risk factors was significantly higher in male nursing staff. In addition, logistic regression analysis showed that age, tobacco and alcohol use, increased waist circumference, physical inactivity and family history of non‐communicable diseases were significant risk factors among nursing staff. Conclusion: The study findings suggest that the nursing staff have suboptimal self‐health concerns on non‐communicable diseases. This situation warrants continued medical education, awareness campaigns on adopting a healthy lifestyle and health promotion. Summary statement: What is already known about this topic? The prevalence of non‐communicable diseases (NCDs) among Indian nursing staff is a growing concern, underscoring the need for comprehensive research and targeted interventions.Despite the significant health risks faced by this demographic, there is a notable lack of data on NCD risk factors specific to Indian nursing professionals. What this paper adds? This paper adds information on the prevalence of NCD risk factors chiefly among nursing staff in the Delhi National Capital Region.Male nursing staff have particularly high NCD risk factors. The implications of this paper: Findings may help develop routine screening programmes for nursing staff, continued nursing education and good, safe nursing practice. [ABSTRACT FROM AUTHOR]

Sarcopenic obesity is the co‐existence of obesity and sarcopenia in individuals aged 40–75 years. The Japanese Working Group on Sarcopenic Obesity has developed diagnostic criteria tailored for the Japanese population, considering their unique characteristics compared with European populations. Our algorithm consists of two steps: screening and diagnosis. The screening of obesity mandates using waist circumference and/or body mass index (BMI) based on national standards, while screening for sarcopenia involves the "finger ring test" in addition to the Asian Working Group for Sarcopenia 2019 criteria. The final diagnosis of sarcopenia involves handgrip strength for low muscle strength, the five‐times chair stand test for low physical function, and limb skeletal muscle mass (corrected for BMI) for low muscle mass. Obesity is assessed by visceral fat area or body fat percentage. Sarcopenic obesity is then categorized into Stage I, with muscle weakness/loss of function, loss of muscle mass, and obesity; or Stage II, which includes complications. Further clinical validation is needed to refine the consensus and age range. Geriatr Gerontol Int 2024; 24: 997–1000. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusions This study investigated the association of physical activity (PA) levels with all‐cause and cardiovascular disease (CVD) mortality risks stratified by adiposity and age.Participants (36 703; mean age: 49.1; 57.1% women) were selected from the Korea National Health and Nutrition Examination Survey 2007–2013. A Cox proportional hazards model was used to examine the association between PA and mortality across different adiposity categories and ages.Median follow‐up was 9.22 years; 2393 individuals died, including 538 with CVD. Compared with normal‐weight controls, underweight individuals had increased all‐cause mortality risk (hazard ratio [HR]: 1.60, 95% confidence interval [CI]: 1.33–1.79). The overweight and obese groups demonstrated reduced mortality risks (HRs: 0.75 [95% CI: 0.67–0.84] and 0.59 [95% CI: 0.51–0.67], respectively). Mortality risk based on abdominal obesity had an HR of 1.22 (95% CI: 1.08–1.37). PA protected against mortality risk most in the obese group performing more than 1000 MET‐min/week and was particularly significant among those who were underweight and obese aged 65 and older.Overweight and obese Asian individuals (based on body mass index) had a lower mortality risk than those with normal body mass index, whereas obesity based on waist circumference was associated with increased mortality. PA protected against mortality across various weight categories, especially in individuals aged ≥65. Geriatr Gerontol Int 2024; ••: ••–••. [ABSTRACT FROM AUTHOR]

Summary: The clinical data analysis found that, compared with the traditional obesity index, the waist-weight ratio (WWR) has more advantages in predicting abnormal bone mineral density in subjects with type 2 diabetes. WWR may serve as a new predictive indicator for osteoporosis in T2DM patients. Purpose: This study was designed to explore the correlation between obesity-related indices and bone mineral density (BMD) and its influencing factors in type 2 diabetes mellitus (T2DM) patients. Methods: A total of 528 patients with type 2 diabetes were recruited. Glucose tolerance, insulin stimulation, and blood biochemical tests were conducted on all participants. All subjects underwent dual-energy X-ray bone density testing and were grouped based on the bone density results. Results: Compared with those in the normal BMD group, the waist-to-body weight ratio (WWR) and weight-adjusted-waist index (WWI) in the osteopenia and osteoporosis groups were significantly greater, while body mass index (BMI) was significantly lower (P < 0.05). The logistic regression results showed that the WWR, WWI, and BMI were independently correlated with abnormal BMD in T2DM patients (P < 0.05). WWR and the WWI were negatively correlated with the T-value of bone density in various parts of the body, while BMI was positively correlated with the T-value of bone density (P < 0.05). The area under the working characteristic curve (AUC) for T2DM patients with abnormal bone mass predicted by the WWR [0.806, 95% CI = (0.770–0.843), P < 0.001] was greater than that for patients with other obesity indicators, such as the WWI and BMI. Conclusion: We found a positive correlation between the WWR and bone density in T2DM patients. Compared with other obesity indicators, such as BMI and WWI, the WWR has a stronger discriminative ability for T2DM patients with abnormal bone density. Therefore, more attention should be given to the WWR in T2DM patients. [ABSTRACT FROM AUTHOR]

This article explores the potential causal relationship between obesity and rosacea, a chronic inflammatory skin disorder. Using Mendelian randomization analysis, the study found no association between genetic susceptibility to obesity and the risk of rosacea. The authors suggest that previous observational studies may have limitations in determining causality and associations due to measurement errors and population differences. Further research is needed to confirm these findings in other races and rosacea subtypes and regions. The study was supported by funding from the Hangzhou Biomedical and Health Industry Development Support Project and the Hangzhou Medical Key Discipline Construction Project, and the authors declare no conflicts of interest.

Purpose: While testosterone therapy can improve the various pathologies associated with adult-onset testosterone deficiency (TD), Summary of Product Characteristics (SPC) of five testosterone preparations caution that treatment may be associated with hypertension. This paper evaluates the impact of testosterone undecanoate (TU) on blood pressure (BP) in men with adult-onset TD. Materials and Methods: Of 737 men with adult-onset TD in an on-going, observational, prospective, cumulative registry, we studied changes in BP using non-parametric sign-rank tests at final assessment and fixed time points. We used multiple regression analysis to establish factors (baseline BP, age, change/baseline waist circumference [WC] and hematocrit [HCT] and follow-up) potentially associated with BP change in men on TU. Results: TU was associated with significant reductions in systolic, diastolic BP and pulse pressure, regardless of antihypertensive therapy (at baseline or during follow-up), larger reductions were seen with concurrent antihypertensive therapy. In men never on antihypertensive agents, median changes (interquartile range [IQR]) in systolic BP, diastolic BP and pulse pressure were -12.5 (-19.0, -8.0), -8.0 (-14.0, -3.0), and -6.0 (-10.0, -1.0) mmHg, respectively at final assessment, with only baseline BP values inversely associated with these changes (HCT and WC were not significantly associated). In men not on TU, systolic BP, diastolic BP, and pulse pressure significantly increased. In the TU treated men only 1 of the 152 men (not on antihypertensive agents at baseline) were started on antihypertensives during follow-up. In contrast 33 of the 202 men on antihypertensives (at baseline or follow-up) had the antihypertensive agent discontinued by the end of the follow-up. Conclusions: TU was associated with lowering of BP during follow-up irrespective of antihypertensive therapy, with greater reductions in men with higher baseline BP. In the context of SPC warnings, our long-term data provide reassurance on the effect of TU on BP. [ABSTRACT FROM AUTHOR]

Aim: To comprehensively examine the associations of childhood and adulthood body size, and child‐to‐adult body size change with adult leucocyte telomere length (LTL). Methods: We included 453 602 participants from the UK Biobank. Childhood body size at the age of 10 years was collected through a questionnaire. Adulthood body size was assessed using body mass index (BMI), waist circumference (WC), waist‐to‐hip ratio (WHR), fat mass index (FMI), and fat‐free mass index (FFMI). Results: Individuals with plumper body size in childhood exhibited shorter LTL in adulthood (−0.0086 [−0.0017, −0.0004]). Adulthood BMI (−0.0286 [−0.0315, −0.0258]), WC (−0.0271 [−0.0303, −0.0238]), WHR (−0.0269 [−0.0308, −0.0230]) and FMI (−0.0396 [−0.0438, −0.0351]) were negatively associated with LTL, whereas FFMI (0.0095 [0.0039, 0.0152]) was positively associated with LTL. Compared to individuals consistently having an average/normal weight in both childhood and adulthood, those who maintained or developed overweight/obesity from childhood to adulthood had a shorter adult LTL, regardless of childhood body size. Notably, the LTL shortening effect was not observed in individuals with plumper body size in childhood but normal weight in adulthood. Conclusions: Childhood and adulthood obesity are both associated with LTL shortening in adulthood. Transitioning to or maintaining overweight/obese status from childhood to adulthood is associated with shorter adult LTL, whereas this effect can be reversed if plumper children become normal weight.

Despite strong evidence in favor of physical activity (PA), adults with autism spectrum disorder (ASD) are not meeting established PA guidelines to engage in at least 150 min of moderate to vigorous PA per week. Barriers to daily PA engagement include limited access to health services, transportation, and reduced self-determined motivation. Telehealth provides a potential alternative to deliver PA programming in a more accessible platform for adults with ASD. This pilot randomized controlled trial (RCT) assessed the preliminary efficacy of a 10-week PA intervention program called Physical Activity Connections via Telehealth (PACT) that utilized telehealth and remote technology, including Fitbit wearable device use, peer-guidance, and individualized home exercise program among adults with ASD. Primary health outcomes, collected at baseline before randomization and post-intervention, included self-determined motivation assessment via Behavioral Exercise Regulation Scale (BREQ-2), self-report PA via Godin-Shephard Leisure-Time Physical Activity Questionnaire (GSLT-PAQ), steps per day PA via Fitbit device, body mass index (BMI), and waist-to-height ratio (WtHR). A total of 18 adults, 11 males, with a mean age of 26.4 years, with a primary diagnosis of ASD participated in the study. Although there were no changes in BMI or WtHR at post-intervention, participants receiving PACT, significantly increased both their self-report PA scores (GSLT-PAQ) from 26 to 68, (p = 0.002), and steps per day from 5,828 to 7,443, (p = 0.015) with a moderate effect size (d = 0.72). The results of this pilot study support peer supported telehealth-based PA intervention for adults with ASD to increase PA. [ABSTRACT FROM AUTHOR]

Background Food provision interventions (eg, produce/food prescriptions, food pharmacies, food voucher programs) that bridge clinic and community settings for improved nutritional health outcomes of at-risk patients have gained momentum. Little is known about the role of nutrition education and potential augmented impact on patient outcomes. Objective To describe intervention designs and outcomes of direct food provision clinic–community programs aimed at improving diabetes-related outcomes (glycated hemoglobin [HbA1c] levels) among patients with type 2 diabetes (T2DM) or prediabetes and food insecurity, and to compare nutrition education components across interventions. Methods The PubMed and Academic Search Complete databases were systematically searched for original peer-reviewed articles (published during 2011–2022) that described the impact of clinic–community food provision programs (ie, produce/food prescriptions, food pharmacies, and food voucher programs) onHbA1c values among adults diagnosed with T2DM or prediabetes and who screened positive for food insecurity or low income. Study designs, intervention approaches, program implementation, and intervention outcomes were described. Results Ten studies representing 8 distinct programs were identified. There was a high degree of variation in the studies' design, implementation, and evaluation. Across the 8 programs, 6 included nutrition education; of these, 1 used a theoretical framework, and 3 incorporated goal setting. Nutrition education covered multiple topical contents, including general nutrition knowledge, fruit and vegetable consumption, and accessing resources (eg, enrolling in the Supplemental Nutrition Assistance Program). Furthermore, the education was delivered through various formats (from 1-on-1 to group-based sessions), educators (community health workers, registered dietitians, physicians), and durations (from a single session to biweekly). All programs with a nutrition education component reported reduced participant HbA1c, and 4 demonstrated an increase in fruit and vegetable purchases or improved dietary quality. The remaining 2 programs that did not include nutrition education yielded mixed results. Conclusion The majority of programs included a nutrition education component; however, there was a high degree of heterogeneity in terms of content, educator, and duration. Patients who participated in programs that included nutrition education had consistent reductions in HbA1c. These observational trends warrant further exploration to conclusively determine the impact of nutrition education on patient outcomes participating in clinic–community food provision programs.

Childhood adversity is linked to psychological, behavioral, and physical health problems, including obesity and cardiometabolic disease. Epigenetic alterations are one pathway through which the effects of early life stress and adversity might persist into adulthood. Epigenetic mechanisms have also been proposed to explain why cardiometabolic health can vary greatly between individuals with similar Body Mass Index (BMIs). We evaluated two independent cross-sectional cohorts of adults without known medical illness, one of which explicitly recruited individuals with early life stress (ELS) and control participants (n = 195), and the other a general community sample (n = 477). In these cohorts, we examine associations between childhood adversity, epigenetic aging, and metabolic health. Childhood adversity was associated with increased GrimAge Acceleration (GAA) in both cohorts, both utilizing a dichotomous yes/no classification (both p < 0.01) as well as a continuous measure using the Childhood Trauma Questionnaire (CTQ) (both p < 0.05). Further investigation demonstrated that CTQ subscales for physical and sexual abuse (both p < 0.05) were associated with increased GAA in both cohorts, whereas physical and emotional neglect were not. In both cohorts, higher CTQ was also associated with higher BMI and increased insulin resistance (both p < 0.05). Finally, we demonstrate a moderating effect of BMI on the relationship between GAA and insulin resistance where GAA correlated with insulin resistance specifically at higher BMIs. These results, which were largely replicated between two independent cohorts, suggest that interactions between epigenetics, obesity, and metabolic health may be important mechanisms through which childhood adversity contributes to long-term physical and metabolic health effects.

Carbonyl stress, a metabolic state characterized by elevated production of reactive carbonyl compounds (RCCs), is closely related to oxidative stress and has been implicated in various diseases. This study aims to investigate carbonyl stress parameters in drug-free bipolar disorder (BD) patients compared to healthy controls, explore their relationship with clinical features, and assess the effect of treatment on these parameters. Patients with a primary diagnosis of a manic episode of BD and healthy controls were recruited. Exclusion criteria included intellectual disability, presence of neurological diseases, chronic medical conditions such as diabetes mellitus and metabolic syndrome, and clinical signs of inflammation. Levels of serum carbonyl stress parameters were determined using high-performance liquid chromatography. Levels of glyoxal (GO) and methylglyoxal (MGO) did not differ between pre- and post-treatment patients, but malondialdehyde (MDA) levels decreased significantly post-treatment. Pre-treatment MGO and MDA levels were higher in patients compared to controls, and these differences persisted post-treatment. After adjusting for BMI and waist circumference, only MDA levels remained significantly higher in patients compared to controls. The study's limitations include the exclusion of female patients, which precluded any assessment of potential gender differences, and the lack of analysis of the effect of specific mood stabilizers or antipsychotic drugs. This study is the first to focus on carbonyl stress markers in BD, specifically GO, MGO, and MDA. MDA levels remained significantly higher in patients, suggesting a potential role in BD pathophysiology. MGO levels were influenced by metabolic parameters, indicating a potential link to neurotoxicity in BD. Further research with larger cohorts is needed to better understand the role of RCCs in BD and their potential as therapeutic targets. • Carbonyl stress is a critical contributor to oxidative stress damage. • RCCs cause direct neuronal damage or via AGEs and ALEs. • Despite decrease with treatment, MDA levels remained elevated compared to healthy controls. • MGO levels, higher in patients with manic episodes, did not change significantly with treatment.

Background: Sarcopenic obesity (SO) is defined as a decrease in lean body mass and an increase in body fat mass (BFM) due to aging. Detecting SO in elderly women is important from the perspective of extending healthy life expectancy. While various indices of SO are currently used, there is no global consensus regarding diagnostic criteria for SO. This study aimed to examine the relationship between obesity indices (waist circumference (WC), body mass index (BMI), and body fat percentage (BFP)) and sarcopenia indices (total body muscle mass (TBM), appendicular lean mass (ALM), skeletal mass index (SMI)), and physical function (gait speed (GS), handgrip strength (HGS)). Methods: Subjects were 170 community-dwelling healthy elderly women aged 65–79 years (mean: 72.7 ± 5.78 years) who underwent measurements for WC, BMI, and BFP. A WC of ≥ 90cm was defined as the obese group, BMI was determined as weight (kg) divided by height squared (m2) and a cutoff of ≥ 25 kg/m2 was used to define the obesity group. BFM was measured using the bioelectrical impedance analysis (BIA) method and BFP was calculated from body weight and a cutoff of ≥ 30% was used to define the obesity group. TBM and ALM (kg) were measured using the BIA method, ALM (kg) was corrected for height (m2) to obtain SMI (kg/m2). Physical function was assessed by GS and HGS, which were measured by the 5-m walk test and a digital grip strength meter, respectively. Results: When obesity was assessed using BMI, WC and BFP, obese individuals had higher TBM, ALM and SMI, and lower GS among the sarcopenia indicators. HGS did not differ significantly between the non-obese and obese groups. Conclusion: Our findings suggest HGS is thought to reflect muscle strength without being affected by obesity indices, suggesting that it may be useful in detecting possible sarcopenia in obese individuals.

Background: Non Communicable Diseases have been identified among top ten global threats by WHO. The role of Screening in Ice berg disease is pre-established. In India, Community Based Assessment Checklist is used to identify high-risk people for Non-Communicable Diseases. Methods: A cross sectional study done among 265 participants from households situated in field practice area attached to Government Medical College, Surat. Data was collected using World Health Organization Stepwise approach to surveillance. Results: Out of total participants 83 (31.32%) were classified high risk (CBAC>4) for Non-Communicable Diseases. Mean age of participants was 43.79 ± 9.36 years. One-tenth 25 (9.4%) of participants were on treatment. Those classified high risk were significantly associated with age (p<0.05), education (p=0.03), occupation (p<0.01). Predictors for Non-Communicable Diseases identified were smoking (aOR=4.7, p=0.003), alcohol (aOR= 2.3, p<0.001), higher Body Mass Index (aOR= 3.8, p=0.03) and higher waist size (aOR= 4.3, p<0.001). Sensitivity, Specificity of tool and Area under Curve were found to be 73.3%, 75.8% and 0.72 respectively. Conclusion: To prevent and control Non-Communicable Diseases key behavioral risk factors to be targeted include smoking, alcohol, higher Body Mass Index and waist size which could be due to unhealthy diet & absence of exercise.

The Chinese visceral adipose index (CVAI) is more significantly associated with cardiometabolic risk factors than other obesity indices. This study investigated the relationship between CVAI and left ventricular (LV) remodeling. This study included 75,132 Koreans who underwent echocardiography during a health checkup. They were grouped according to quartile levels of the CVAI, body mass index (BMI), waist circumference (WC), and visceral adiposity index (VAI). LV remodeling was defined as the presence of abnormal relative wall thickness (ARWT) and left ventricular hypertrophy (LVH). Multivariate adjusted logistic regression analysis (adjusted OR [95% confidence interval]) was used to analyze the association between ARWT and LVH according to the quartile levels of each index. Receiver operating characteristic (ROC) graphs and areas under the curve (AUC) were calculated to identify the predictive ability of the indices for ARWT and LVH. ARWT was associated proportionally with CVAI quartiles in both men (second quartile: 1.42 [1.29–1.56], third quartile: 1.61 [1.46–1.77], fourth quartile: 2.01 [1.84–2.21]), and women (second quartile: 1.06 [0.78–1.45], third quartile: 1.15 [0.86–1.55], and fourth quartile: 2.09 [1.56–2.80]). LVH was significantly associated with third (1.74 [1.07–2.83]) and fourth quartile (1.94 [1.18–3.20]) groups of CVAI in women. ROC and AUC analyses indicated that CVAI was superior to other indices in predicting ARWT in men and LVH and ARWT in women. The CVAI is an effective surrogate marker of LV remodeling, particularly in women. • CVAI predicted the likelihood of LVH and ARWT better than BMI, waist circumference, and VAI in women. • Our study suggests that the VAI has poor predictive power for LV remodeling, whereas the CVAI is significantly better in the Asian population.

Objectives: Obesity/overweight and metabolic anomalies are known to be associated with elevated cardiovascular disease (CVD) risk. However, there is a paucity of research exploring the association between different body weights, varying metabolic statuses, and the occurrence of CVD in the Chinese population. Thus, we performed this study to explore the relation between different metabolic overweight/obesity phenotypes and the prevalence of CVD. Methods: We analyzed data from 9075 participants in the Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal (REACTION) study. Participants were classified into four metabolic phenotypes based on their metabolic status and obesity/overweight status. Regression analysis was used to evaluate the relationship between CVD and different groups. Additionally, we conducted a subgroup analysis to further explore the relationship between CVD and different metabolic abnormalities. Results: Compared to metabolically healthy non‐overweight/obesity (MHNO) individuals, both overweight/obesity and metabolic anomalies were positively associated with CVD prevalence. Among other metabolically unhealthy and overweight/obesity phenotypes, metabolically healthy overweight/obesity (MHO) generally exhibited a comparatively lower association with CVD. In the elderly, high waist circumference was significantly associated with CVD, rather than body weight. Further analysis revealed that hypertension had the strongest association with CVD. Conclusion: Elderly individuals should place more emphasis on managing their waist circumference rather than only on BMI. CVD prevention should focus on both body weight management and treatment of metabolic diseases, with particular emphasis on antihypertensive therapy. Summary: Our study used two types of criteria to define metabolic unhealthiness and explored the association between different metabolic overweight/obesity phenotypes and CVD.In the elderly, high waist circumference, rather than on high BMI, was associated with CVD.Hypertension had the strongest association with CVD compared to other metabolic anomalies.

Background: Menopause induces physiological changes in women, including increased risks of obesity, cardiovascular diseases, and muscle loss, which can be mitigated by physical exercise. This study aimed to evaluate the effects of a 12-week multicomponent exercise programme, performed 2 or 3 days per week, on health and fitness parameters in postmenopausal women. Methods: Eighty-three postmenopausal women (aged 50–65 years) were randomly assigned to three groups: control group (CG, n = 27), 2 days/week exercise group (EG2, n = 28), and 3 days/week exercise group (EG3, n = 28). The intervention included strength, balance, aerobic, and flexibility exercises. Anthropometric measurements (body weight, BMI, waist-to-hip ratio, lean body mass, body fat percentage), lipid profile, and isometric strength were assessed pre- and post-intervention. Data were analysed using a repeated-measures ANOVA, with p < 0.05 considered significant. Results: Significant reductions in body weight, BMI, and waist-to-hip ratio were observed in EG2 and EG3 compared to CG. Lean body mass increased significantly in both EG2 (p < 0.001, ES = 1.37) and EG3 (p < 0.001, ES = 1.50). EG3 showed a greater reduction in body fat percentage than EG2 (p = 0.049). Strength and balance improved significantly in both experimental groups compared to CG, with no significant differences between EG2 and EG3. EG3 also showed superior improvements in lipid profile compared to EG2 and CG. Conclusion: A multicomponent exercise programme, particularly with higher frequency (3 days per week), improves body composition, strength, balance, and lipid profile in postmenopausal women.

Background: Postmenopausal women frequently encounter a range of symptoms, including fatigue, diminished physical strength, reduced energy levels, vasomotor symptoms such as hot flushes, and vaginal atrophy, all of which adversely affect their overall quality of life. Engaging in physical activity and structured exercise may effectively alleviate these symptoms and enhance overall well-being. The present study aimed to investigate the relationship between physical activity and quality of life in postmenopausal Greek women. Methods: This cross-sectional clinical study included 219 postmenopausal women. Women with natural menopause for at least 12 consecutive months were enrolled in this descriptive, cross-sectional study. The female participants were asked to fill out the International Physical Activity Questionnaire-short form (IPAQ), the Hospital Anxiety and Depression Scale (HADS), and the EuroQol (EQ-5D-5L) instrument. Anthropometric measurements included weight, height, and waist circumference measurements. Results: A total of 219 postmenopausal women with an age of 61.4 ± 6.1 years and body mass index (BMI) of 25.6 ± 3.7 kg/m2 were studied. Out of the total postmenopausal women studied, 64.8% were physically active. The mean value of MET-min/week was M = 1383.46 ± 1030.12. Physical activity among postmenopausal Greek women showed a strong correlation of PA with quality of life (r = 0.5; p ≤ 0.001) and age (r = 0.55; p ≤ 0.001) and a medium correlation with the HADS (r = 0.4; p ≤ 0.05). Conclusions: There was a 64.8% prevalence of physically active postmenopausal Greek women. The findings underscore the significance of fostering physical activity and quality of life among postmenopausal women to formulate efficacious therapeutic interventions. The results demonstrate a correlation between physical activity and the age of female participants, quality of life, and the HADS and can be used to improve postmenopausal women's physical activity levels, which is recommended as a strategy for improving the quality of life in postmenopausal women.

Background/Objectives: Nutrition plays a significant role in preventive medicine, as up to 80% of chronic diseases could be avoided by adhering to healthy dietary principles. The aim of our study was to identify dietary habits, awareness, and nutrition knowledge in a random sample of Polish healthcare students and professionals. Methods: Initially, a total screened sample consisted of 1287 respondents, yet the actual response/participation rate was 634/1287. A validated questionnaire for the Polish population, the Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN), was used for the assessment. Results: The majority of respondents were females (84.2% of medical students and 87.2% of healthcare professionals), current non-smokers (79.6% of medical students and 85.2% of healthcare professionals), and had a normal waist circumference (76.3% of medical students and 63.1% of healthcare professionals). Both clinical dieticians and students studying clinical dietetics received significantly different scores of dietary indexes (pro-healthy pHDI-10 and non-healthy nHDI-14) vs. respective groups of respondents. Both healthcare students and professionals who self-reported better nutritional knowledge indeed yielded significantly better results in the dietary indexes as well as nutritional knowledge scores. The nutrition knowledge score was positively correlated with pHDI-10 and negatively correlated with nHDI-14, BMI, age, and waist circumference. Conclusions: Our results illustrate lifestyle trends among Polish healthcare students and professionals, and such results should encourage the development of evidence-based dietary policies targeting healthcare providers. High-quality continuing nutrition education should be obligatorily provided to all healthcare providers to enhance their dietary awareness as well as ensure high quality of care and outcomes achieved by the Polish healthcare system.

(1) Background: High blood pressure (HBP), overweight, and obesity are common, growing public health problems worldwide. The aim of this study was to evaluate associations between changes in body weight status and HBP among Lithuanian children and adolescents during the COVID-19 pandemic. (2) Methods: In this study, we analysed data on blood pressure and anthropometric measurements of 2430 children and adolescents aged 8–18 years, who participated in both the baseline study conducted before the COVID-19 pandemic (from November 2019 to March 2020) and the follow-up study during the COVID-19 pandemic (from November 2021 to April 2022). Multivariate logistic regression analysis was used to estimate the associations between changes in weight status categories and HBP. (3) Results: At baseline, 17.1% of the subjects had overweight, 5.9% had obesity, 5.6% had abdominal obesity, and 23.7% had HBP, whereas at the follow-up, these percentages increased to 20.1%, 8.2%, 6.8%, and 27.4%, respectively. Compared to schoolchildren who maintained normal weight from baseline to the follow-up period, subjects who newly developed overweight/obesity and those who remained with persistent overweight/obesity had increased odds of HBP, with adjusted odds ratios (aORs) of 1.95 (p < 0.001) and 2.58 (p < 0.001), respectively. In subjects who transitioned from overweight/obesity to normal weight, the odds of HBP were slightly increased, with an aOR of 1.14 (p = 0.598), but the change was not statistically significant (p > 0.05). (4) Conclusions: This study observed an increase in the prevalence of overweight, obesity, and HBP among schoolchildren during the COVID-19 pandemic. The study also suggested that changes from normal body weight status at baseline to overweight/obesity during follow-up, especially persistent overweight/obesity, were associated with higher odds of HBP in Lithuanian children and adolescents during the COVID-19 pandemic.

Introduction Studies link hypovitaminosis D to be significantly associated with poor glycemic control, heightened inflammation, and risk of complications. Studies recommend fasting or calorie restriction as a useful measure to achieve diabetic reversal. The present study explores if therapeutic fasting is associated with improvement in the vitamin D levels and other clinical outcomes related to type 2 diabetes mellitus (T2DM). Methods This observational study included 26 T2DM patients exposed to a 10-day medically supervised fasting (≈ 500–1000 Kcal/day) in a complementary medicine facility. Levels of vitamin D, B12, fasting blood sugar (FBS), blood pressure, anthropometric measures, World Health Organization Quality of Life, disease perception (Brief Illness Perception Questionnaire), and self-reported vitality were measured at the baseline and the 10th day. Results Significant improvement in the levels of vitamin D (p = 0.000), B12 (p = 0.03), and reduction in FBS levels (p = 0.001), blood pressure, body mass index, waist and hip circumference (p ≤ 0.05), and improvement in quality of life, vitality, and disease perception (p < 0.001) were observed by the end of 10th day. FBS shared a negative correlation with vitamin D levels (males r = –0.1, females r = –0.48). Conclusion The present findings provide insights into the probable mechanisms by which therapeutic fasting modulates the progression of T2DM. Nevertheless, large-scale randomized controlled trials are warranted to validate the present findings. [ABSTRACT FROM AUTHOR]

Jawarish Bisbasa, a Unani polyherbal formulation, is used traditionally in the clinical treatment of central obesity. It is a polyherbal semi-solid preparation of eleven medicinal herbs mainly used as spices. Aim of the study: The main objective of this study was to evaluate the effect of Unani Formulation Jawarish Bisbasa and compare the changes in lipid profiles and Anthropometric Parameters before and after treatment in patients with hyperlipidaemia associated with central obesity. Materials and methods: An open-label clinical validation study was conducted at the Regional Research Institute of Unani Medicine, Mumbai research OPD. The study included 120 cases of each gender with BMIs of 34.99 kg/ m2 for men and 32.49 kg/m2 for women, while 88 cases completed the study. Enrolled cases received Unani Formulation Jawarish Bisbasa 7gm BD twice daily with warm water for 8 weeks. The pathological investigations and Anthropometric Parameters related to the study, particularly BMI, Waist Circumference, Waist to hip ratio, Saggital Abdominal Diameter, LDL, HDL, and VLDL values were statistically analysed at baseline, first, follow- up, and at the end of the study by using unpaired Student t-test and one-way analysis of variance. (ANOVA). Extremely significant BMI, Waist Circumference, Waist to hip ratio, Saggital Abdominal Diameter, and lowering of ESR, Total cholesterol, and Triglycerides when the values of before-treatment and after-treatment were analyzed in hyperlipidemia associated with central obesity. There were no side effects reported during the treatment. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to quantify changes over time in waist circumference (WC) relative to BMI by sex in the Americas (United States, Mexico, Chile, and Peru) and England. Methods: Data from adults aged 25 to 64 years between 1997 and 2020 were analyzed, and US data were stratified by race and ethnicity groups. Sex‐specific BMI and WC means and obesity and abdominal obesity prevalence were compared between the first and last surveys. Using data from all survey years, secular changes across the BMI and WC distributions were estimated, applying quantile regression models. BMI was added as a predictor of WC to estimate secular changes in WC relative to BMI. Interaction terms were included in all models to evaluate differences by sex. Results: BMI and WC (except for Peru) showed larger secular increases at the upper‐tails of the distributions in both sexes. Increases at the 50th and 75th WC percentiles relative to BMI were more pronounced in women than in men, with larger increases in US non‐Hispanic White individuals and in England. In men, increases in WC independent of BMI were most evident in Mexico. Conclusions: Disease risk associated with visceral fat is potentially underestimated by national surveillance efforts that quantify only secular changes in BMI. [ABSTRACT FROM AUTHOR]

Background: The sedentary aspects of many U.S. occupations and the amount of time American workers spend in the workplace make it an ideal location to implement health promotion programs. Methods: This study assessed the effectiveness of a free smartphone app with a goal-setting feature to increase physical activity (PA) and impact anthropometric, body mass (BM), and body composition (BC) changes among overweight and obese women within a community health workforce. Eighteen overweight and obese (body mass index [BMI] = 32.18 ± 4.48 kg/m2), adult (50.73 ± 8.76 years), female volunteers, tracked daily steps with a free smartphone app (StridekickTM) over an 8-week period. Pre- and post-program body composition (BC) measurements included: relative (%) body fat (BF), fat mass (FM), fat-free mass (FFM), and lean mass (LM), using dual X-ray absorptiometry (DEXA scan), and five anthropometric measurements (biceps, waist, abdomen, hips, and thigh). Findings: Pre- to post-program average daily steps resulted in significant anthropometric changes for biceps, hips, and thigh measures, with encouraging changes in FFM, LM, and relative (%) BF. The goal-setting feature of the app did not result in significant differences between the experimental and control groups. No differences were noted in FM, BMI, waist, and abdomen or step goals compared with steps completed. Conclusions: An occupational PA health promotion intervention program that tracked daily steps through the StridekickTM smartphone app resulted in anthropometric, BM, and BC changes. Application to Practice: The workplace is an ideal location to affect change in health behaviors via a free smartphone app to increase PA and improve health. [ABSTRACT FROM AUTHOR]

Background: The association between dietary cholesterol and metabolic diseases remains controversial. However, the majority of studies focus on egg intake, and there is a limitation in the availability of prospective cohort studies. Our study examined the association between dietary cholesterol and the incidence risk of metabolic syndrome (MetS) in middle aged adults using large prospective cohort study in Republic of Korea. Methods: The Health Examinees cohort from the Korean Genome and Epidemiology Study was used from baseline to follow-up. Dietary cholesterol intake was assessed by the validated semi-quantitative food frequency questionnaire. Participants were classified as quintile groups according to adjusted dietary cholesterol for total energy intake. MetS was defined as more than 3 of the 5 components of MetS. Hazard ratio (HR) and 95% confidence intervals (CI) for MetS were evaluated by multivariable cox regression analyses. Results: Of the total 40,578 participants, metabolic syndrome developed in 4,172 (10.28%) individuals during an average follow-up period of approximately 4.76 years. Dietary cholesterol did not exhibit a significant association with the risk of MetS after adjusting for potential confounding factors, but a trend was observed indicating an increased risk with higher intake (p for trend = 0.044). Among the components of MetS, the incidence risk of high waist circumference (HR: 1.164, 95% CI: 1.049–1.290), high blood pressure (HR: 1.188, 95% CI: 1.075–1.313), high serum triglyceride (HR: 1.132, 95% CI: 1.044–1.227) and high fasting blood glucose (HR: 1.217, 95% CI: 1.132–1.308) in the group that consumed the highest dietary cholesterol intake was increased compared with the group that consumed the lowest dietary cholesterol intake. Dose-response relationship suggested a positive linear association between dietary cholesterol intake and the risk of high waist circumference (p-linearity = 0.004), blood pressure (p-linearity = 0.012), and triglycerides (p-linearity = 0.005). Conclusion: This study suggests a positive association between dietary cholesterol intake and the risk of MetS and its components (abdominal obesity, hypertension, hypertriglyceridemia, and hyperglycemia) in middle-aged Korean adults.

Objective: One of the main features of polycystic ovary syndrome (PCOS) is increased adipose tissue, which can result in hormonal disturbances. In the present study, we aimed to investigate which indicator of obesity could better associate with hormonal disturbances in PCOS women. Methods: In this cross-sectional analysis, women with PCOS were included according to the Rotterdam criteria. Fasting blood samples were analyzed for biochemical, metabolic, and hormonal parameters. Anthropometric measures comprised body composition indices (assessed by bioelectric impedance analysis [BIA]), waist circumference, body mass index (BMI), and waist-to-height ratio (WHtR). Linear regression modeling was used to assess the association between anthropometric indices and hormonal imbalance, adjusted for age, mensuration status, and the homeostasis model assessment-estimated insulin resistance (HOMA-IR). Receiver operating characteristics (ROC) curves were utilized to ascertain the sensitivity, specificity, and optimal cut-off points of various anthropometric indices in identifying hyperandrogenism. Results: A total of 129 PCOS women with a median (interquartile range [IQR]) age of 32.0 (23.0–32.0) years and a median BMI of 26.3 (23.00-29.70) kg/m2 were enrolled. In the adjusted linear regression model, BMI (β = 0.053, P < 0.001), waist circumference (β = 0.021, P = 0.001), WHtR (β = 3.325, P = 0.002), total fat mass (β = 0.021, P = 0.002), trunk fat mass (β = 0.038, P = 0.006), and leg fat mass (β = 0.045, P = 0.004) were positively associated with free androgen index (FAI). In addition, BMI (β=−0.017, P = 0.003), waist circumference (β=−0.008, P = 0.002), WHtR (β=−1.167, P = 0.004), total fat mass (β=−0.008, P=0.003), trunk fat mass (β=−0.017, P=0.001), and leg fat mass (β=−0.018, P=0.004) were negatively associated with the serum level of sex hormone binding globulin (SHBG). WHtR showed the greatest area under the curve (AUC) value (AUC = 0.676, P = 0.001) for identifying hyperandrogenism (FAI ≥ 4.97 or total testosterone ≥ 0.7 ng/mL) in PCOS women with corresponding sensitivity of 87.30% and specificity of 39.70%. Conclusions: WHtR is related to hyperandrogenism in PCOS better than other anthropometric measures. [ABSTRACT FROM AUTHOR]

Background: Given the established link between obesity and hyperuricemia (HUA), the research want to investigate the relationship between different obesity indices and HUA, and further analyze which obesity index can better predict HUA. Methods: The data were obtained from a longitudinal study involving middle-aged and elderly populations in Dalian, China. The research encompassed individuals who exhibited typical uric acid levels initially and tracked their progress over a three-year period. 8 obesity indices were evaluated retrospectively. Subgroup analyses were conducted to identify susceptible populations. Restricted cubic splines (RCS) were utilized to model the dose-response relationships between obesity indices and HUA. Receiver operating characteristic (ROC) curves were applied to visualize and compare the predictive value of both traditional and new obesity indices for HUA. Results: Among 4,112 individuals with normal baseline uric acid levels, 950 developed HUA. Significant associations with HUA were observed for body mass index (BMI), waist circumference (WC), body roundness index (BRI), cardiometabolic index (CMI), visceral adiposity index (VAI), Chinese visceral adiposity index (CVAI), lipid accumulation product (LAP), and abdominal volume index (AVI). Subgroup analysis indicated that all obesity indices proved more effective in assessing the onset of HUA in women without Metabolic Syndrome (MetS). Further analysis using RCS revealed non-linear dose-response relationships between LAP, CMI, VAI, and HUA in males, with similar non-linear relationships observed for all indices in females. The results from the ROC curves indicate that LAP may serve as a better predictor of HUA in males, and CVAI may serve as a better predictor in females. Conclusion: HUA is closely associated with obesity indices. Among females, CVAI emerges as the preferred predictive index for HUA. In males, LAP emerges as the preferred predictive index for HUA.

Background: Randomized controlled trials have confirmed the effectiveness of four prevalent caloric restriction regimens in reducing obesity-related health risks. However, there is no consensus on the optimal regimen for weight management in adults. Methods: We systematically searched PubMed, Embase, Web of Science, and Cochrane CENTRAL up to January 15, 2024, for randomized controlled trials (RCT) involving adults, evaluating the weight-loss effects of alternate day fasting (ADF), short-term fasting (STF), time-restricted eating (TRE), and continuous energy restriction (CER). The primary outcome was body weight, with secondary outcomes including BMI, fat mass, lean mass, waist circumference, fasting glucose, HOMA-IR, and adverse events. Bayesian network meta-analysis was conducted, ranking regimens using the surface under the cumulative ranking curve and the probability of being the best. Study quality was assessed using the Confidence in Network Meta-Analysis tool. Results: Data from 47 RCTs (representing 3363 participants) were included. ADF showed the most significant body weight loss (Mean difference (MD): -3.42; 95% Confidence interval (CI): -4.28 to -2.55), followed by TRE (MD: -2.25; 95% CI: -2.92 to -1.59). STF (MD: -1.87; 95% CI: -3.32 to -0.56) and CER (MD: -1.59; 95% CI: -2.42 to -0.79) rank third and fourth, respectively. STF lead to decline in lean mass (MD: -1.26; 95% CI: -2.16, -0.47). TRE showed benefits on fasting glucose (MD: -2.98; 95% CI: -4.7, -1.26). Subgroup analysis revealed all four caloric restriction regimens likely lead to modest weight loss after 1–3 months, with ADF ranked highest, but by 4–6 months, varying degrees of weight regain occur, particularly with CER, while interventions lasting 7–12 months may result in effective weight loss, with TRE potentially ranking first during both the 4–6 months and 7–12 months periods. ADF showing fewer and shorter-lasting physical symptoms. Conclusion: All four included regiments were effective in reducing body weight, with ADF likely having the most significant impact. Each regimen likely leads to modest weight loss after 1–3 months, followed by weight regain by 4–6 months. However, interventions lasting 7–12 months achieve greater weight loss overall.
