Background: This study investigates how lifestyle factors and westernization contribute to obesity and examines the influence of body mass index (BMI) changes and lifestyle factors on "lipitension," a significant risk factor for heart disease and metabolic syndrome. Methods: This prospective study focused on women aged 20–64 without pre-existing hypertension and dyslipidemia who underwent regular medical checkups between April 2016 and March 2022. Anthropometric measurements and blood pressure, along with low-density lipoprotein, high-density lipoprotein, and triglycerides levels, were assessed. Results: Over an average 46.5-month follow-up, 11.5% of initially healthy young and middle-aged women developed lipitension. Categorizing participants based on BMI changes revealed stable (63.8%), decreased (12.5%), and increased (23.8%) groups within this 11.5%. Increased BMI is linked with a heightened hazard risk for lipitension. Women with increased BMI who refrained from snacking (aHR [95% confidence interval (CI)] = 2.750 [1.433–5.279]), avoided late-night eating (aHR [95% CI] = 1.346 [1.032–1.754]), and engaged in alcohol consumption (aHR [95% CI] = 2.037 [1.138–3.646]) showed an elevated risk. Conversely, within the decreased BMI group, behaviors like skipping breakfast (aHR [95% CI] = 0.190 [0.047–0.764]), eating quickly (aHR [95% CI] = 0.457 [0.215–0.972]), and not eating late (aHR [95% CI] = 0.665 [0.467–0.948]) were associated to a reduced lipitension. Subgroup analysis for women with BMI <23 revealed specific behaviors influencing lipitension risk in both BMI-increased and BMI-stable groups. Conclusion: Customized interventions, including for women with BMI <23, enhance heart health, mitigating global lifestyle diseases and obesity. [ABSTRACT FROM AUTHOR]

Slum environment may pose risk to child health and nutrition. This study assessed the risks of anemia among under five-year-old children, five years after implementing a nutrition education and counseling intervention in two urban slums in Nairobi, Kenya. A cross-sectional study was conducted in May 2018 as a follow-up of a randomized controlled study carried out between 2012–2015. A trained nurse measured hemoglobin levels of 438 children from households which participated in the initial study. Multivariate logistic regression was conducted to identify risks of anemia. The mean (+ SD) age of the children was 55.9 (5.3) months and mean (+ SD) hemoglobin was 10.7 (1.5) g/dL. Anemia prevalence was 59.8%, 33.9% had mild, 24.7% moderate, and 1.2% severe anemia. Absence of home toilet (AOR = 3.31; 95% CI, 1.20–9.09), household which paid to use a toilet facility (AOR = 1.86; 95% CI, 1.12–3.08), child's frequency of eating colored fruits and vegetables (AOR = 0.28; 95% CI, 0.08–0.96), meat and meat products (AOR = 0.31; 95% CI, 0.23–6.01), number of meals a child aged <15years ate a day preceding the study (AOR = 1.49; 95% CI, 1.14–1.98), and a mother who had a history of anemia (AOR = 2.89; 95% CI, 1.22–12.01), were factors significantly associated with child's anemia status. The environment of urban informal settings influences child anemia status. Further studies with interventions are therefore required in order to improve sanitation facilities and access to meats, fruits, and vegetables in urban slums through innovative kitchen gardens and small animal husbandry.

Little is known about the usefulness of biomarkers to study the influence of prenatal nutrition supplementation in improving child growth. Anthropometry is not always straightforward to understand how nutrition might impact growth, especially in settings with high rates of malnutrition and infections. We examined the effects of prenatal supplementation on growth and growth biomarkers and the relationship between anthropometric measures and growth biomarkers of children at 4.5 and 9 years of age. Children were enrolled from a longitudinal cohort, where mothers were randomized into daily supplementation with either early‐food (≤9 gestation week [GW]) or usual‐food (~20 GW) (608 kcal 6 days/week); they were further randomized to receive 30‐mg or 60‐mg iron with 400‐μg folic acid, or multiple micronutrients (MM) in rural Bangladesh. Anthropometric data were collected from mothers at GW8 and children at 4.5 (n = 640) and 9 years (n = 536). Fasting blood was collected from children at each age. Early‐food supplementation showed reduced stunting and underweight at 4.5 and 9 years age respectively compared to usual‐food. Prenatal supplementations did not have any effect on growth biomarkers except for STAT5b expression which was lower in the early‐food compared to the usual‐food group (β = −0.21; 95 CI% = −0.36, −0.07). Plasma concentrations of 25‐hydroxy vitamin D and calcium were both inversely associated with weight‐for‐age and body mass index‐for‐age Z‐scores at 9 years, particularly in early‐food and MM groups. Although there was minimal effect on child growth by prenatal supplementations, the associations of biomarkers with anthropometric indices were predominantly driven by timing of food or MM supplementations.

Background Handgrip strength is an indicator of muscle function and a predictor of health outcomes. However, only a few studies have examined the association between handgrip strength and the development of kidney damage. This study aimed to investigate the longitudinal association of handgrip strength with kidney damage in a general Japanese population. Methods This prospective cohort study enrolled participants with normal kidney function who attended annual health check-ups in Ibaraki Prefecture, Japan, between April 2016 and March 2020. Clinical information, including data from blood and urine tests, physiological examinations, and handgrip strength tests, was collected at enrollment. Lifestyle information was also collected via a self-administered questionnaire. The study participants were followed up for the progression of kidney damage until March 2023. Relative handgrip strength was calculated by dividing the handgrip strength by the body mass index to adjust for differences in body mass. A Cox proportional hazards model was used to examine the relationship between relative handgrip strength and the progression of kidney damage. Results A total of 4304 participants with normal kidney function were enrolled in this study. During the mean follow-up period of approximately 4 years (SD 1.8 years), 15.4% of the participants developed kidney damage. After adjusting for covariates, higher relative handgrip strength was associated with a lower risk of kidney damage in men (HR = 0.63, 95% CI: 0.43 - 0.90; p = 0.012), but no significant association was observed in women. Conclusions Higher relative handgrip strength is associated with a lower risk of kidney damage in men. This finding highlights the importance of muscle strength in preventing kidney damage., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.
