Middle age is increasingly accepted as a key period during which individuals are susceptible to the effect of environmental and lifestyle factors. Emerging research indicates that dietary factors play a crucial role in brain health and cognitive function, and studies in both animals and humans have demonstrated that dietary interventions can mitigate cognitive impairment. Specifically, magnesium has been shown to enhance learning and memory, and magnesium deficiency is associated with impaired hippocampal-dependent memory formation in animal studies. The aim of this study was to examine if supplementation with a magnesium-rich marine mineral blend (MMB) could alter middle-age-related cognitive impairment. Young and middle-aged rats were given access to a control diet or an experimental diet formulated with an MMB for 4 weeks before undergoing a series of behavioral assessments. Supplementation of MMB to middle-aged rats rescued a deficit in cognitive impairment, specifically a pattern separation paradigm that is sensitive to alterations in a type of brain plasticity called neurogenesis. It had no effect on general activity in the open field or performance on other hippocampal-associated tasks. Changes in cognitive function occur as a predictable consequence of aging. Research into whether modification of dietary factors, such as this MMB, may play a role in the prevention of age-related cognitive impairment warrants further investigation.

Intergenerational solidarity is multidimensional in nature, but the role of filial eldecare norms in structuring intergenerational solidarity is less understood. We examine how filial eldercare norms expressed in early adulthood and midlife are associated with intergenerational solidarity with older parents and how this association varies across parent-child gender combinations. We used data from 1985 to 2005 waves of the Longitudinal Study of Generation when the generation of interest was 32 and 52 years of age, respectively. A three-step latent class approach, culminating with a multinomial logistic regression, was conducted on a sample of 198 mother-son, 279 mother-daughter, 155 father-son, and 209 father-daughter dyads. A tight-knit intergenerational type was uniquely identified in mother-daughter relations, and a social unsupportive type was uniquely identified in father-son and father-daughter relations. Daughters expressing stronger filial norms in early adulthood were more likely in middle adulthood to belong to a tight-knit relational type with mothers and a social unsupportive and intimate but distant relational type with fathers, compared to a detached relational type; these effects were mediated by contemporaneously measured filial norms. Our study complements previous studies on the relationship between filial eldercare norms and intergenerational solidarity with older parents by showing that these norms exert an influence by virtue of being stable in adult daughters over 20 years into middle age. These findings demonstrate that eldercare norms expressed by daughters prior to their parents' transition to old age structure intergenerational relationships in later life, suggesting that such norms are better considered as long-term endowments than as situational in their origins.

Numeracy, the ability to understand and use basic probability and numerical concepts, is associated with diverse positive outcomes across the lifespan. Prior cross-sectional research on numeracy has generally found a negative association with age, but positive correlations with male gender, education attainment, and measures of fluid and crystallized intelligence have been more robust. Age effects on cognitive functioning are well established, but little is known about longitudinal trends of numeracy into older age. The present study investigates longitudinal age effects on numeracy using a sample of 524 adults (2008 Agerange = 20-78) from the RAND American Life Panel. Participants completed a numeracy measure in both 2008 and 2019, a span of 11 years. Using a linear mixed-effect model to predict numeracy scores, a significant interaction between the year of testing and the quadric age term shows a decline in numeracy scores beginning in later middle age, a trend that falls in between those previously found for crystallized and fluid cognitive abilities. Numeracy declines are somewhat mitigated for males and those with higher education, but the interaction of the two variables did not return a clear pattern of results. Prior research has shown that numeracy is positively related to the quality of health and financial decisions and, ultimately, more positive health and economic outcomes. The implications of age declines in numeracy are discussed in relation to health and financial decision-making, tasks that remain relevant into old age.

We examined transient elastography assessed hepatic steatosis and fibrosis distributions and relationships with body composition in a representative United States population sample.Liver stiffness and controlled attenuation parameter (CAP) were assessed on 4870 non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, and Hispanic men and women aged 20 years and over in the National Health and Nutrition Examination Survey (NHANES) 2017-2018. Participants underwent anthropometry and dual-energy x-ray absorptiometry (DXA).Compared to women, men had higher mean CAP (274.2 dB/m vs 254.4 dB/m) and liver stiffness (6.4 kPa vs 5.5 kPa). CAP and liver stiffness increased through middle age and markedly with BMI. In multivariate-adjusted analysis, CAP in the upper quartile was associated with increased age, BMI, waist-to-hip ratio, diabetes, hypertension, alanine aminotransferase (ALT) and C-reactive protein and decreased HDL cholesterol. After adjustment, non-Hispanic Blacks had lower CAP and non-Hispanic Asians had higher CAP. In multivariate-adjusted analysis, liver stiffness in the upper quartile was associated with male sex, increased age, BMI, diabetes, hepatitis C virus positivity, ALT and CAP. Lower stiffness among Non-Hispanic Asians was not significant after adjustment for BMI. DXA trunk and extremity fat mass were positively related to both CAP and liver stiffness with multivariate adjustment (P.001 for each). Results were similar with CAP and liver stiffness as continuous characteristics.In the United States population, increased anthropometric and DXA body composition measures were associated with higher CAP and liver stiffness. Racial-ethnic differences observed merit further research to elucidate the burden of obesity and liver health disparities.

Aim This study investigated the relationship between birth physique and cardiovascular risk factors in Japanese urban residents aged 40 years and more. Methods A self-administered questionnaire on birth physique was performed among 624 individuals (165 men and 459 women) who participated in the KOBE study. We examined whether self-reported birth physique and available recorded birth weights matched for 72 participants. Then the association between birth physique and risk factors for all participants was examined by gender. Body size at birth in the questionnaire (large, medium, small) was set as an exposure and laboratory values from the baseline survey (2010-2011) were used as outcomes. Results Mean (standard deviation) recorded birth weight of 72 participants was 3665 (318), 3051 (300), and 2653 (199) g, in the large, medium, and small group, respectively. In the analysis for all participants, odds ratio for having both hypertension and impaired glucose tolerance were significantly higher in the small versus large birth weight group, which was 7.42 (95% CI 1.75-31.50) for men and 4.44 (95% CI 1.14-17.30) for women after adjusting for age, body mass index, smoking/alcohol/exercise habits, and menstrual status in women. Similar results were observed in participants with recorded birth weight. Conclusions The present study indicates that individuals with small physique at birth might be at higher risk for hypertension and impaired glucose tolerance in middle age compared to those with large birth weight.

Purpose Secretory carcinoma (SC) of the salivary gland, formerly known as mammary analogue secretory carcinoma, is an uncommon and fairly newly described, low grade malignant neoplasm of the salivary gland. Given the small number of cases reported in the literature to date, treatment guidelines are scarce. This study aimed to describe the clinical characteristics of SC, discuss prior management strategies, and provide recommendations for future treatment. Methods We performed a systematic review of all the cases of SC reported in the literature since it was first recognized in 2010. Using Pubmed, Crossref, and Google Scholar, we identified all articles reporting cases of SC. Results We identified 657 cases of SC in 109 articles. In addition, we provided 2 new cases, for a total of 659 cases in 110 articles. To our knowledge, this is the largest review of cases of SC in the literature to date. We summarized the clinical characteristics of SC, as well as the nodal status, clinical management, recurrence rate, and death rate. Conclusions SC occurs on average in middle age (with a large age range), presents most often initially as localized disease without metastasis, and has a low but not insignificant recurrence rate. Deaths have been reported. The generalized recommendations for treatment of SC are in line with those of other low-grade salivary gland malignancies.

Background The high rate of obesity, ownership of smartphones, and online search for nutrition and dieting information among African American women (AAW) provide a unique opportunity to develop cost-effective, accessible, and acceptable mHealth weight management programs for them. Furthermore, they should participate in the development and evaluation of these programs. Objective To explore ideal components of a culturally relevant mHealth weight management program for AAW and to examine how these components may vary by age group. Design Twelve focus group triads were conducted with AAW in north central Florida. The framework method was used to manage, organize, synthesize, and analyze data themes by age groups: 18 to 29 (young), 30 to 50 (middle age), and 51+ (older). Participants/setting Thirty-six smartphone owners who expressed a desire to lose weight were recruited through several community partnerships. Results Based on body mass index (BMI), young women were classified as overweight (BMI 26.23 ± 6.7), middle-aged women as obese (BMI30.72 ± 8.31), and older women as obese (BMI 31.03 ± 5.67). Most searched online for dieting information within the past 12 months. Five overarching themes for designing mHealth weight management programs were identified: (1) holistic program that goes beyond dieting; (2) social media integration for support and sense of community; (3) self-monitoring app; (4) two-way text messaging; and (5) programs of varying lengths and meaningful incentives. Conclusion AAW were receptive to mHealth weight management programs, which may be appealing during and after the COVID-19 pandemic. Holistic programs of 4 to 6 weeks that addressed stress eating, had a social media component, and included a few educational texts per week may be appealing to AAW.

Background: Urgent action is required to identify socially acceptable alcohol reduction options for heavy-drinking midlife Australian women. This study represents innovation in public health research to explore how current trends in popular wellness culture toward ‘sober curiosity’ (i.e., an interest in what reducing alcohol consumption would or could be like) and normalising non-drinking could increase women’s preparedness to reduce alcohol consumption. Methods: Qualitative interviews were undertaken with 27 midlife Australian women (aged 45–64) living in Adelaide, Melbourne and Sydney in different social class groups (working, middle and affluent-class) to explore their perceptions of sober curiosity. Results: Women were unequally distributed across social-classes and accordingly the social-class analysis considered proportionally the volume of data at particular codes. Regardless, social-class patterns in women’s preparedness to reduce alcohol consumption were generated through data analysis. Affluent women’s preparedness to reduce alcohol consumption stemmed from a desire for self-regulation and to retain control; middle-class women’s preparedness to reduce alcohol was part of performing civility and respectability and working-class women’s preparedness to reduce alcohol was highly challenging. Options are provided for alcohol reduction targeting the social contexts of consumption (the things that lead midlife women to feel prepared to reduce drinking) according to levels of disadvantage. Conclusion: Our findings reinstate the importance of recognising social class in public health disease prevention; validating that socially determined factors which shape daily living also shape health outcomes and this results in inequities for women in the lowest class positions to reduce alcohol and related risks.

Summary Background An understanding of whether early-life depression is associated with physical multimorbidity could be instrumental for the development of preventive measures and the integrated management of depression. We therefore aimed to map out the cumulative incidence of physical multimorbidity over adulthood, and to determine the association between the presence of depressive symptoms during early adulthood and the development of physical multimorbidity in middle age. Methods In this observational cohort study, we used pooled data from the 1958 National Child Development Study (NCDS) and the 1970 British Cohort Study (BCS). Cohort waves were pooled in each decade of adult life available (when cohort members were aged 26 years in the BCS and 23 years in the NCDS [baseline]; 34 years in the BCS and 33 years in the NCDS [age 34 BCS/33 NCDS]; 42 years in the BCS and NCDS [age 42 BCS/NCDS]; and 46 years in the BCS and 50 years in the NCDS [age 46 BCS/50 NCDS]). We included participants who had completed the nine-item Malaise Inventory at baseline, and did not have a history of physical multimorbidity, any physical multimorbidity at baseline, or the presence of depressive symptoms before the development of physical multimorbidity. The presence of depressive symptoms was determined using the nine-item Malaise Inventory (cutoff score ≥4). Physical multimorbidity was defined as having at least two measures of any of the following ten self-reported groups of long-term conditions: asthma or bronchitis; backache; bladder or kidney conditions; cancer; cardiovascular conditions; convulsions or epilepsy; diabetes; hearing conditions; migraine; and stomach, bowel, or gall conditions. Cumulative incidence (with 95% CI) of physical multimorbidity was calculated for each decade considered after baseline, with physical multimorbidity being assessed as both a dichotomous and categorical variable. The association between depressive symptoms and the development of physical multimorbidity was assessed using adjusted relative risk ratios (with 95% CIs). Findings Analyses included 15 845 participants, of whom 4001 (25·25%; 95% CI 24·57–25·93) had depressive symptoms at baseline and 11 844 (74·75%; 74·07–75·42) did not. The cumulative incidence of physical multimorbidity (dichotomous) ranged over the study period from 2263 (18·44%; 95% CI 17·75–18·14) of 12 273 participants at age 34 BCS/33 NCDS, to 4496 (42·90%; 41·95–43·85) of 10 481 participants at age 46 BCS/50 NCDS, and was consistently higher in participants with depressive symptoms at baseline. The adjusted relative risk of physical multimorbidity was higher in participants with depressive symptoms than in those without and remained stable over the study period (adjusted relative rate ratio 1·67, 95% CI 1·50–1·87, at age 34 BCS/33 NCDS; 1·63, 1·48–1·79, at age 42 BCS/NCDS; and 1·58, 1·43–1·73, at age 46 BCS/50 NCDS). Interpretation The presence of depressive symptoms during early adulthood is associated with an increased risk of the development of physical multimorbidity in middle age. Although further research about the drivers of this relationship is needed, these results could help to enhance the integrated management of individuals with depressive symptoms and the development of preventive strategies to reduce the effect and burden of physical multimorbidity.

There is sometimes a divergence between brain atrophy and impairments in cognitive function. The present study aimed to assess the relationship between cognitive function and the grey-matter brain healthcare quotient (GM-BHQ), which represents brain volume as a deviation value. In addition, we aimed to investigate lifestyle factors that can help maintain cognitive function despite brain atrophy. A total of 1,757 adults included in a Japanese MRI brain screening cohort underwent MRI. We classified the participants into two age groups: under 65 years old (young adult/middle age group) and over 64 years old (elder group). The GM-BHQ was more strongly correlated with cognitive function in the young adult/middle age group than in the elder group (p .01). Regression analysis revealed that years of education was associated with the maintenance of cognitive function despite brain atrophy (p .05). In conclusion, our findings suggest that the relationship between brain volume and cognitive function becomes more obscure with age.

Background: Clinical and psychosocial profiles of persons living with mental illness (PMI) in non-hospital settings in India have not been adequately studied. Aim: This study describes the profile of PMI living in non-hospital settings by focussing on variables like functioning and social networks. Method: Residents of all available residential facilities in one district area were surveyed and descriptive data was obtained. Socio occupational functioning was assessed using the Social and Occupational Functioning Scale (SOFS) and social network was measured by modified Lubben Social Network Scale-6 (LSNS-6). Results: A total of nine centres housing 491 residents (7–128) were surveyed via field visits. The mean age of the residents was 49 ± 14.0 years. Fifty per cent of them were never married, 22% were separated or widowed. Almost half of the people had psychotic disorders, while diagnosis could not be delineated in a quarter of the population. Almost half the people reached the facilities with the help of their families, while 40% were brought by police or volunteers who found them wandering. Impairment in socio-occupational functioning was only mild in 90% of residents, while 60% did not contact relatives or friends in the past 3 months. Conclusion: PMI living in non-hospital residential facilities were on average in their middle age and were deficient in marital bonds and other social support. They had reached the centres with the help of extended family or by police/volunteers who rescued them from wandering status. Nevertheless, most of them had only mild to moderate levels of impairment, and their functional capacity was good for independent living in the community with support. Hence, newer models of supported housing that provide greater community reintegration, like independent shared housing within regular neighbourhoods, can be tried. In persons with residual family ties, providing continuous community-based support may help re-establish family integration.

INTRODUCTION The prevalence of hypertension (HTN) is increasing in the middle-aged population, but few studies have examined the prevalence and risk factors associated with hypertension in this age group. AIM To estimate the prevalence of HTN and its associated demographic risk factors in the middle-aged population (30-59 years) of Iran. METHODS In this cross-sectional study, 4112 middle-aged people from five provinces of the country were selected by multi-stage sampling and entered into the study. HTN or high blood pressure (HBP) was defined as systolic blood pressure ≥ 140 mmHg and diastolic blood pressure ≥ 90 mmHg. The relationship between demographic risk factors and the prevalence of HTN was assessed by multivariate logistic regression in Stata software version 14. RESULTS The prevalence of HTN was 17.8% (95% CI 16.5-19.0) and was higher in women than men (19.1% vs. 16.5%). The prevalence of HTN in three studied age groups including 30-39, 40-49 and 50-59 years were 7.2, 18.7 and 38.0%, respectively. The frequency of HTN in urban residents was higher than rural residents (18.4% vs. 15.6%). The chance of developing hypertension in urban residents (OR 1.25), overweight (OR 3.94) and obese persons (OR 7.54) was higher. CONCLUSIONS Hypertension has a relatively high prevalence in the middle-aged Iranian population. According to our results, age, living in urban regions, being illiterate, overweight and obesity are independent risk factors for HBP. It seems that the administration of prevention programs in general population especially in younger ages based on existing risk factors is a necessity.

Purpose To describe health-related quality of life (HRQoL) using the Wound-Quality of Life (Wound-QoL) questionnaire for those individuals referred to an academic medical center wound clinic. Design Prospective, descriptive study. Subjects and setting One hundred eleven participants receiving care in an academic medical center wound clinic in the Southeastern United States. The sample comprised 67 males (60.4%) and 44 females (39.6%) with wounds of 6 major etiologies. Methods From June 2019 through May 2020, a convenience sample of 111 individuals completed the Wound-QoL questionnaire at the initial visit to the wound clinic. The Wound-QoL questionnaire is a valid and reliable tool consisting of 17 questions related to wound-QoL measured on a 5-point Likert scale, ranging from 0 (not at all affected) to 4 (very much affected). The questions are assigned to the 3 subscales: "body," "psyche," and "everyday life." The Wound-QoL individual items, subscales, and the total wound score (TWS) were calculated as mean values of the item scores, ranging from 0 to 4, where higher values correspond to decreased HRQoL. The TWS is defined as the sum of the 17 item responses, with values ranging from 0 to 68. Descriptive and parametric statistics were used to analyze the data from the Wound-QoL questionnaire. Results The mean TWS was approximately 3 points higher for Whites (n = 84) than for Blacks (n = 27) (32.42, SD = 17.96 vs 29.51, SD = 19.39), but this difference was not significant (P = .473). An independent-samples t test of TWS versus sex was not significant (P = .446). The TWS by age category was significant (P = .015), showing differences in mean scores based on age category. We found that the youngest (ages 17-39 years) and oldest (ages 70-98 years) participants were less bothered by their wounds in almost all respects than those in the middle age range (ages 40-69 years). The individual item means varied between 0.84 and 2.72, out of a possible range of 0 to 4. The highest means were for items on the emotional subscale with means from 1.93 to 2.72. Analysis of variance was used to examine the TWS and the 3 subscales over the 6 wound types; none were found to be significant (TWS: P = .454, body: P = .722, psyche: P = .452, everyday life: P = .087). Conclusion Wound-QoL questionnaire scores indicated that the greatest impact of a wound on HRQoL was on the emotional subscale. These 4 items are related to the individual expressing worry, fear, unhappiness, or frustration with wound healing. The Wound-QoL questionnaire may be used to evaluate the impact the wound has on the individual's HRQoL.

Background Depression imposes immense public health burden, demonstrating an urgent need of the identification of modifiable risk factors. Only a few cohort studies have analyzed the association between Mediterranean dietary pattern (MDP) and depression but with mixed results. We examined the impact of MDP on clinically ascertained depression in a large population-based dataset. Methods In 1991/92, detailed information on diet, using a food frequency questionnaire, and potential confounding factors (body weight, height, educational attainment, smoking, previous diabetes and hypertension, and physical activity) was collected, in a random sample of 49,261 Swedish women aged 29-49. Adherence to MDP was calculated. Clinical depression was extracted from the National Patient Register. Study participants were followed up through 2012. Results During an average follow-up of 20.4 years, 1677 incident cases of depression were diagnosed. We observed a lower risk of depression for medium (score 4-5) and high (6-9) adherence to MDP, compared with low (0-3) adherence (Medium: hazard ratio (HR) = 0.90, 95% confidence interval (CI) = 0.81-1.00; High: HR = 0.82, 95%CI = 0.71-0.94). Per unit increase of adherence, the risk of depression was reduced by 5% (HR = 0.95, 95%CI = 0.92-0.98). The association became stronger when restricting to severe form of depression (HR = 0.51, 95%CI = 0.33-0.76). The HRs were higher from age 50 onward both over the first and the second 10-year follow-up period, compared with before age 50, indicating stronger association with increasing age. Results remained after extensive sensitivity analyses. Conclusion Higher adherence to a Mediterranean diet at middle age was associated with a lower risk of depression later in life among Swedish women.

Midlife aerobic exercise may significantly impact age-related changes in the cerebro- and cardiovascular regulations. This study investigated the associations of midlife aerobic exercise with dynamic cerebral autoregulation (dCA), cardiovagal baroreflex sensitivity (BRS), and central arterial stiffness. Twenty middle-aged athletes (MA) who had aerobic training for >10 yr were compared with 20 young (YS) and 20 middle-aged sedentary (MS) adults. Beat-to-beat cerebral blood flow velocity, blood pressure (BP), and heart rate were measured at rest and during forced BP oscillations induced by repeated sit-stand maneuvers at 0.05 Hz. Transfer function analysis was used to calculate dCA and BRS parameters. Carotid distensibility was measured by ultrasonography. MA had the highest peak oxygen uptake (V̇o(2peak)) among all groups. During forced BP oscillations, MS showed lower BRS gain than YS, but this age-related reduction was absent in MA. Conversely, dCA was similar among all groups. At rest, BRS and dCA gains at low frequency (∼0.1 Hz) were higher in the MA than in MS and YS groups. Carotid distensibility was similar between MA and YS groups, but it was lower in the MS. Across all subjects, V̇o(2peak) was positively associated with BRS gains at rest and during forced BP oscillations (r = 0.257∼0.382, P = 0.003∼0.050) and carotid distensibility (r = 0.428∼0.490, P = 0.001). Furthermore, dCA gain at rest and carotid distensibility were positively correlated with BRS gain at rest in YS and MA groups (all P < 0.05). These findings suggest that midlife aerobic exercise improves central arterial elasticity and BRS, which may contribute to cerebral blood flow (CBF) regulation through dCA. NEW & NOTEWORTHY Middle-aged athletes (MA) showed intact dynamic cerebral autoregulation (dCA) during sit-stand maneuvers when compared with young (YS) and middle-aged sedentary (MS) adults. Conversely, MA showed the significant attenuation of age-related carotid distensibility and baroreflex sensitivity (BRS) impairments. In MA and YS groups, BRS was positively associated with dCA gain at rest and carotid distensibility. Our findings suggest that midlife aerobic exercise improves BRS by reducing central arterial stiffness, which contributes to CBF regulation through dCA.

Serum urate levels have been shown to be correlated with risk for incident cardiovascular disease (CVD) events among middle-aged or older adults. However, serum urate trajectory during young adulthood and its association with CVD events has been understudied. Using serum urate measurements collected at baseline and 10, 15, 20 years after baseline from 3563 Coronary Artery Risk Development in Young Adults (CARDIA) participants [mean age 25.1±3.6 (18–30) years at baseline (Year 0, 1985–86); 46.3% African American; 56.1% female], we determined sex-specific serum urate trajectories using SAS PROC TRAJ. We estimated hazard ratios (HR) for incident CVD events (coronary heart disease, heart failure, and stroke) occurring after the Year 20 exam through 2017. We identified 3 serum urate trajectories by sex, including low-stable (n=1251), moderate-stable (n=1761), and high-increasing (n=551). Over a median 10.6 years of follow-up, 157 incident CVD events occurred. Participants among the high-increasing trajectory group had 2.89 (95% confidence interval, 1.88–4.43) times greater risk for CVD compared to the low-stable trajectory group. The association was attenuated after adjustment for blood pressure levels during young adulthood. In conclusion, high-increasing serum urate trajectory during young adulthood was associated with incident CVD by middle age, and the association may be explained by blood pressure levels during the exposure period.

Introduction The prevalence of stroke in SCD patients was reported to be around 4%; however, the pediatric category was among the higher risk group for stroke compared to young and middle age adults. Furthermore, the risk of OSA increases in SCD children. The objective of this study is to calculate the prevalence of stroke in children with SCD with and without obstructive sleep apnea. Method This is a cross-sectional study held at two major tertiary hospitals in Jeddah, Saudi Arabia. Inclusion criteria included patients aged between 2 and 18 at the time of enrollment with confirmed SCD. The primary outcome of the study was at least one documented episode of stroke over the last 3 years. OSA was assessed using PSQ. Results A total of 150 children with SCD were included in the study. The mean age was 9.6 (±4.3). Most of the sample (85.3%) were sickle-cell anemia with HbSS. Children who were positive for OSA were at higher odds of having a stroke [OR 2.97; 95% CI 1.13-7.75 (P = 0.02)]. The relationship between OSA and stroke was not significant in the multivariant analysis. Conclusion Patients who had OSA had a higher prevalence of stroke compared to non-OSA patients by 16% with almost three times higher odds. The difference was statistically significant in bivariant but not multivariant analysis. The rate of hospitalization, emergency visit, and blood transfusion were not affected by OSA status. Screening for OSA in high-risk patients such as SCD children and early management could prevent the risk of SCD complications.

Objectives Age differences in affective experience across adulthood are widely documented. According to the circumplex model of affect consists of 2 aspects—valence (positive vs negative) and arousal (low activation vs high activation). Prior research on age differences has primarily focused on the valence aspect. However, little is known about age differences in daily affect of high and low arousal. Method The present study examined age differences in daily dynamics (i.e., mean levels, variability, and inertia) of negative affect (NA) and positive affect (PA) of high and low arousal in a sample of 492 adults aged 21–91. Participants completed daily affect ratings for 21 consecutive days. Results Age was negatively and linearly related to mean levels of both high-arousal and low-arousal NA. Both high-arousal and low-arousal PA mean levels showed increases after middle age. Further, age was related to lower variability in both NA and PA regardless of arousal. Additionally, high-arousal NA inertia showed a linear decrease with age, whereas low-arousal PA inertia showed an inverted-U pattern with age. After controlling for mean levels of affect, the associations between age and affect variability remained significant, whereas the associations between age and affect inertia did not. Discussion The affective profile of older age is characterized by lower mean levels of NA, higher mean levels of PA, lower affect variability, and less persistence in high-arousal NA and low-arousal PA in daily life. Our results contribute to a nuanced understanding of which affective processes improve with age and which do not.

As aging women take relatively high counts of medications and nutritional supplements, each addition to their supplements roster increases the likelihood of experiencing adverse health outcomes. Given these public health implications, we isolate the effects of chronological age and old age stereotypes in driving up the number of nutritional supplements taken by middle age and older women in the United States. We use multiple models that converge on the finding that middle age women, but not older women, who highly endorse negative old age stereotypes take more supplements than their age peers who fail to highly endorse negative old age stereotypes.

ObjectivesThe risk of suicide among UK military veterans remains unclear. Few recent studies have been undertaken, and most studies found no clear evidence of increased risk. We used data from the Trends in Scottish Veterans Health cohort to investigate suicides up to 2017 in order to examine whether there have been any changes in the long-term pattern of veteran suicides since our earlier study to 2012, and to compare trends in the risk of suicide among veterans with matched non-veterans.MethodRetrospective cohort study of 78 000 veterans and 253 000 non-veterans born between 1945 and 1995, matched for age, sex and area of residence, using survival analysis to examine the risk of suicide in veterans in comparison with non-veterans overall and by subgroup, and to investigate associations with specific mental health conditions.ResultsUp to 37 years of follow-up, 388 (0.5%) veterans and 1531 (0.6%) non-veterans died from suicide. The risk of suicide among veterans did not differ from non-veterans overall. Increased risk among early service leavers was explained by differences in deprivation, and the previously reported increased risk in female veterans is now confined to older women. Suicide was most common in the fifth decade of life, and around 20 years postservice. A history of mood disorder or post-traumatic stress disorder was non-significantly more common in veterans.ConclusionsVeterans are not at increased risk of suicide overall. The highest risk for both men and women is in middle age, many years after leaving service.

To further understand psychopathy within a Developmental and Life-Course Criminology perspective, the current article investigates the stability and change in psychopathy from childhood to middle age. The Cambridge Study in delinquent development is a prospective longitudinal study of 411 males, where psychopathy was coded based on contemporanously collected data from young people and in adulthood. Psychopathy in middle age was assessed in a medical interview. The findings indicate a high degree of stability of psychopathy across the life-course. To explain stability and change, childhood factors that might predict this were investigated. Few factors were related to stability and change across the life-course. Poor supervision, poor housing, a large family, and having a convicted father were associated with any change. A depressed mother was associated with a later decrease in psychopathy. This investigation has implications not only for the downward extension of psychopathy to childhood, but also for the understanding of the development of criminal and antisocial behavior.

Introduction The demands of parenthood may limit the pursuit of moderate-to-vigorous intensity physical activity (MVPA), establish inactivity patterns into middle age, and lead to long-term poorer health and well-being. The purpose of this study was to examine the efficacy of a couple-based planning skills intervention to support MVPA from baseline (~2 months after birth) up to 6 months later in first-time parents. Study design Randomized trial. Participants 264 parents (132 couples) at the 2-month point of parenting their first child. Intervention Couples were randomized to either an education control (n=58 couples) or an education plus planning condition (n=74 couples). Main outcome measures MVPA was assessed via accelerometry and self-report at baseline, 6 weeks, 3 months, and 6 months. Health-related fitness (aerobic fitness, muscular strength, flexibility) and BMI tests were conducted at baseline and 6 months. Rolling recruitment was between 2014 and 2017. Results The accelerometry results had large amounts of missing data that were not missing at random, so only self-reported MVPA was analyzed. Dyadic multilevel modeling conducted in 2020 showed that mothers’ MVPA had a significant quadratic pattern over time that was similar for both conditions, and BMI decreased while strength and flexibility increased. Fathers did not have significant outcomes. Participants who were not meeting MVPA guidelines at baseline responded to the education plus planning condition with increased MVPA (father B=1.31, mother B=1.14, p Conclusions Mothers may be more responsive than fathers to MVPA interventions in early parenthood. Already active parents likely have little to be gained from additional intervention. Future research is needed to effectively promote MVPA during fatherhood and identify novel ways to sustain PA past the early response to an intervention.

Background Delirium is a distressing neurocognitive disorder recently linked to sleep disturbances. However, the longitudinal relationship between sleep and delirium remains unclear. This study assessed the associations of poor sleep burden, and its trajectory, with delirium risk during hospitalization. Methods About 321 818 participants from the UK Biobank (mean age 58 ± 8 years [SD]; range 37–74 years) reported (2006–2010) sleep traits (sleep duration, excessive daytime sleepiness, insomnia-type complaints, napping, and chronotype—a closely related circadian measure for sleep timing), aggregated into a sleep burden score (0–9). New-onset delirium (n = 4 775) was obtained from hospitalization records during a 12-year median follow-up. About 42 291 (mean age 64 ± 8 years; range 44–83 years) had repeat sleep assessment on average 8 years after their first. Results In the baseline cohort, Cox proportional hazards models showed that moderate (aggregate scores = 4–5) and severe (scores = 6–9) poor sleep burden groups were 18% (hazard ratio = 1.18 [95% confidence interval: 1.08–1.28], p < .001) and 57% (1.57 [1.38–1.80], p < .001), more likely to develop delirium, respectively. The latter risk magnitude is equivalent to 2 additional cardiovascular risks. These findings appeared robust when restricted to postoperative delirium and after exclusion of underlying dementia. Higher sleep burden was also associated with delirium in the follow-up cohort. Worsening sleep burden (score increase ≥2 vs no change) further increased the risk for delirium (1.79 [1.23–2.62], p = .002) independent of their baseline sleep score and time lag. The risk was highest in those younger than 65 years at baseline (p for interaction Conclusion Poor sleep burden and worsening trajectory were associated with increased risk for delirium; promotion of sleep health may be important for those at higher risk.

Background: Individuals with left ventricular (LV) hypertrophy and elevated cardiac biomarkers in middle age are at increased risk for the development of heart failure with preserved ejection fraction. Prolonged exercise training reverses the LV stiffening associated with healthy but sedentary aging; however, whether it can also normalize LV myocardial stiffness in patients at high risk for heart failure with preserved ejection fraction is unknown. In a prospective, randomized controlled trial, we hypothesized that 1-year prolonged exercise training would reduce LV myocardial stiffness in patients with LV hypertrophy. Methods: Forty-six patients with LV hypertrophy (LV septum >11 mm) and elevated cardiac biomarkers (N-terminal pro-B-type natriuretic peptide [>40 pg/mL] or high-sensitivity troponin T [>0.6 pg/mL]) were randomly assigned to either 1 year of high-intensity exercise training (n=30) or attention control (n=16). Right-heart catheterization and 3-dimensional echocardiography were performed while preload was manipulated using both lower body negative pressure and rapid saline infusion to define the LV end-diastolic pressure-volume relationship. A constant representing LV myocardial stiffness was calculated from the following: P=S×[Exp {a (V–V 0 )}–1], where “P” is transmural pressure (pulmonary capillary wedge pressure – right atrial pressure), “S” is the pressure asymptote of the curve, “V” is the LV end-diastolic volume index, “V 0 ” is equilibrium volume, and “a” is the constant that characterizes LV myocardial stiffness. Results: Thirty-one participants (exercise group [n=20]: 54±6 years, 65% male; and controls (n=11): 51±6 years, 55% male) completed the study. One year of exercise training increased max by 21% (baseline 26.0±5.3 to 1 year later 31.3±5.8 mL·min –1 ·kg –1 , P P =0.0004), whereas there was no significant change in max in controls (baseline 24.6±3.4 to 1 year later 24.2±4.1 mL·min –1 ·kg –1 , P =0.986). LV myocardial stiffness was reduced (right and downward shift in the end-diastolic pressure-volume relationship; LV myocardial stiffness: baseline 0.062±0.020 to 1 year later 0.031±0.009), whereas there was no significant change in controls (baseline 0.061±0.033 to 1 year later 0.066±0.031, interaction P =0.001). Conclusions: In patients with LV hypertrophy and elevated cardiac biomarkers (stage B heart failure with preserved ejection fraction), 1 year of exercise training reduced LV myocardial stiffness. Thus, exercise training may provide protection against the future risk of heart failure with preserved ejection fraction in such patients.

Fibrosing alopecia in a pattern distribution (FAPD) is a unique entity which presents clinicopathological characteristics of both male/female pattern androgenetic alopecia (AGA) and lichen planopilaris (LPP). This entity was first reported in 2000 and its criteria was recently proposed. Etiopathogenesis of FAPD has been speculated to be immunological destruction involving miniaturized hair follicles but still remains elusive. To date, few Asian FAPD cases have been reported in the literature. In this study, Japanese FAPD cases were identified based on the aforementioned criteria and analyzed to delineate clinicopathological characteristics. By retrospectively revisiting medical records and clinical photographs, 24 Japanese cases comprising 17 women and seven men were diagnosed as FAPD. All male patients had disease onset by their early 30s, whereas most female patients had developed the condition in middle age or later. Their initial diagnoses prior to the diagnostic confirmation of FAPD were mostly LPP. Based on the clinical phenotypes, the cases were categorized into AGA and LPP types. These subtypes were characterized by foremost trichoscopic and histopathological findings of AGA or LPP, respectively. Unlike previously reported cases, our patients tended to manifest hair loss in both vertex and frontal to mid-scalp with minimal regression of anterior hairline, manifesting unique "parachute" pattern, which has been reported as a representative characteristic of East Asian AGA in the literature. Anti-inflammatory therapies seemed to be effective to deter hair loss but insufficient to achieve improvement. Further accumulation of the cases is necessary; however, these findings may provide additional pathophysiological insights into FAPD and highlight uniqueness of the etiology and clinical phenotype of Japanese FAPD putatively influenced by racial predispositions.

ObjectivesTo determine the association between moderate-to-vigorous intensity physical activity (MVPA) trajectories (course over age and time) through the adult life course and onset of metabolic disease (diabetes and dyslipidaemia).MethodsWe analysed prospective community-based cohort data of 5115 participants in the Coronary Artery Risk Development in Young Adults study, who were black and white men and women aged 18–30 years at baseline (1985–1986) at four urban sites, collected through 30 years of follow-up. Individualised MVPA trajectories were developed for each participant using linear mixed models.ResultsLower estimated MVPA score at age 18 was associated with a 12% (95% CI 6% to 18%) higher odds of incident diabetes, a 4% (95% CI 1% to 7%) higher odds of incident low high-density lipoprotein (HDL) and a 6% (95% CI 2% to 11%) higher odds of incident high triglycerides. Each additional annual 1-unit reduction in the MVPA score was associated with a 6% (95% CI 4% to 9%) higher annual odds of diabetes incidence and a 4% (95% CI 2% to 6%) higher annual odds of high triglyceride incidence. Analysing various MVPA trajectory groups, participants who were in the most active group at age 18 (over 300 min/week), but with sharp declines in midlife, had higher odds of high low-density lipoprotein and low HDL incidence, compared with those in the most active group at age 18 with subsequent gains.ConclusionGiven recent trends in declining MVPA across the life course and associated metabolic disease risk, young adulthood is an important time period for interventions to increase and begin the maintenance of MVPA.

Despite the growing body of evidence on lung function trajectories over the life course and their risk factors, the literature has not been systematically synthesized. Publications related to lung function trajectories were identified from PubMed, EMBASE and CINAHL databases. Two authors independently identified publications for inclusion according to predefined selection criteria. Studies that modelled lung function trajectories and reported associated exposures were included. Meta-analyses could not be conducted due to heterogeneity in the exposures and methods used to model lung function trajectories. Nine publications were eligible for inclusion of which four used group-based trajectory modelling to model lung function trajectories, while five used latent profile analysis. Studies with repeated lung function measurements over the life course identified more trajectories than others. Only one study spanning from childhood to middle age reported catch-up trajectory. The following childhood risk factors for subnormal lung function trajectories were observed in at least across two studies: low birth weight, early wheezing, asthma, allergic sensitization, eczema, allergic rhinitis, lower respiratory tract infections, family history of asthma and second-hand smoke exposure. Adult active asthma and personal cigarette smoking were observed to be associated with accelerated decline lung trajectories. Our review identified 10 risk factors associated with the growth, catch-up, reduced plateau and decline trajectories of lung function. Intervention directed at childhood asthma and infections, and tobacco smoke exposure at all ages would help promote lung health and prevent subnormal lung function trajectories.

The purpose of this study was to investigate whether long-term television viewing patterns, a common sedentary behavior, in early to mid-adulthood is associated with gray matter brain volume in midlife and if this is independent of physical activity. We evaluated 599 participants (51% female, 44% black, mean age 30.3 ± 3.5 at baseline and 50.2 ± 3.5years at follow-up and MRI) from the prospective Coronary Artery Risk Development in Young Adults (CARDIA) study. We assessed television patterns with repeated interviewer-administered questionnaire spanning 20years. Structural MRI (3T) measures of frontal cortex, entorhinal cortex, hippocampal, and total gray matter volumes were assessed at midlife. Over the 20years, participants reported viewing an average of 2.5 ± 1.7h of television per day (range: 0-10h). After multivariable adjustment, greater television viewing was negatively associated with gray matter volume in the frontal (β = - 0.77; p = 0.01) and entorhinal cortex (β = - 23.83; p = 0.05) as well as total gray matter (β = - 2.09; p = 0.003) but not hippocampus. These results remained unchanged after additional adjustment for physical activity. For each one standard deviation increase in television viewing, the difference in gray matter volume z-score was approximately 0.06 less for each of the three regions (p

Recent studies have reported on an association between endurance sport, atrial enlargement and the development of lone atrial fibrillation in younger, male cohorts. The atrial morphology and function of middle‐aged, physically‐active males and females have not been well studied. We hypothesized that middle‐aged males would demonstrate larger left atrium (LA) and right atrium (RA) volumes compared to females, but atrial function would not differ. LA and RA volume and function were evaluated at rest in healthy adults, using a standardized 3.0Tesla cardiac magnetic resonance protocol. Physical activity, medical history, and maximal oxygen consumption (V˙O2peak) were also assessed. Physically‐active, middle‐aged men (n = 60; 54 ± 5 years old) and women (n = 30; 54 ± 5 years old) completed this study. Males had a higher body mass index, systolic blood pressure, and V˙O2peak than females (p

The pulsatile stress in the microcirculation may contribute to development or progression of chronic kidney disease. However, there is no prospective data confirming whether pulsatile stress in early life affect renal function in middle age. The authors performed a longitudinal analysis of 1738 participants aged 6–15 years at baseline, an ongoing Adolescent Prospective Cohort with a follow‐up of 30 years. The authors evaluated the association between pulsatile stress in childhood and adult subclinical renal damage (SRD), adjusting for related covariates. Pulsatile stress was calculated as resting heart rate × pulse pressure. Renal function was assessed with estimated glomerular filtration rate (eGFR) and urine albumin‐to‐creatinine ratio (uACR). The results showed that pulsatile stress in childhood was associated with adult SRD (Relative Risk, 1.43; p = .032), and the predictive value of combined pulse pressure and heart rate for SRD was higher than either of them alone. The high pulsatile stress in childhood increased the risk of adult SRD in males (RR, 1.92; p = .003), but this association was not found in females (RR, 0.91; p = .729). Further, the participants were categorized into four groups on the basis of pulsatile stress status in childhood and adulthood. Male patients with high pulsatile stress during childhood but normal pulsatile stress as adults still had an increased risk of SRD (RR, 2.04; 95% CI, 1.18–3.54), while female patients did not (RR, 0.96; 95% CI, 0.46–1.99). The study demonstrated that high pulsatile stress in childhood significantly increased the risk of adult SRD, especially in males. Adequate control of pulse pressure and heart rate from childhood, in the long‐term, is very important for preventing kidney damage.

Background: The number of people living with dementia is rising globally due to population aging. Mass media campaigns which aim to reduce the risk of people developing dementia have been conducted across many countries, but few have reported evaluation findings. Objective: The present study investigated the impact of the Your Brain Matters dementia risk reduction campaign in Australia. Methods: The campaign was evaluated by observational cross-sectional surveys of 1000 Australian adults aged 18–75 years before and 24 months after delivery. The national campaign utilized multiple media channels to promote messages about the importance of brain health and reducing the risk of dementia. Dementia risk reduction knowledge, confidence, intentions and actions were measured at baseline and follow-up, and analyzed 2019–2020. Results: Earned television and radio were the most common exposure channels. The proportion of people who understood that it is beneficial to take action to reduce dementia risk before middle age increased (54.1% to 59.4%, OR 1.20 95% CI: 1.01–1.44). There was also an increase (28.5% to 32.8%, OR 1.30, 95% CI: 1.07–1.59) in the proportion who reported taking action to improve brain health. There was no improvement in knowledge about vascular risk factors, or confidence to reduce personal dementia risk. Conclusion: The findings showed some receptivity and positive responses to messages about the benefits of taking action to reduce the risk of dementia. The campaign demonstrated the potential for generating news coverage about this issue, which should highlight the preventive benefits of vascular health behaviors.

Objective Coronavirus disease 2019 (COVID-19) has disproportionally affected communities of color. We aimed to determine what factors are associated with COVID-19 testing and test positivity in an underrepresented, understudied, and underreported (U3) population of mothers. Methods This study included 2996 middle-aged mothers of the Boston Birth Cohort (a sample of predominantly urban, low-income, Black and Hispanic mothers) who were enrolled shortly after they gave birth and followed onward at the Boston Medical Center. COVID-19 testing and test positivity were defined by the SARS-CoV-2 nucleic acid test. Two-probit Heckman selection models were performed to identify factors associated with test positivity while accounting for potential selection associated with COVID testing. Results The mean (SD) age of study mothers was 41.9 (±7.7) years. In the sample, 1741 (58.1%) and 667 (22.3%) mothers were self-identified as Black and Hispanic, respectively. A total of 396 mothers had COVID-19 testing and of those, 95 mothers tested positive from March 2020 to February 2021. Among a multitude of factors examined, factors associated with the probability of being tested were obesity (RR = 1.27; 95% confidence interval (CI): 1.08–1.49); and presence of preexisting chronic medical conditions including hypertension, asthma, stroke, and other comorbidities (coronary heart disease, chronic kidney disease, and sickle cell disease) with a corresponding RR = 1.40 (95% CI: 1.23–1.60); 1.29 (95% CI: 1.11–1.50); 1.44 (95% CI: 1.23–1.68); and 1.37 (95% CI: 1.12–1.67), respectively. Factors associated with higher incident risk of a positive COVID-19 test were body mass index, birthplace outside of the USA, and being without a college-level education. Conclusions This study demonstrated the intersectionality of obesity and social factors in modulating incident risk of COVID-19 in this sample of US Black and Hispanic middle-aged mothers. Methodologically, our findings underscore the importance of accounting for potential selection bias in COVID-19 testing in order to obtain unbiased estimates of COVID-19 infection.

Contemporary conceptualizations of mindfulness refer to paying attention to the present moment with an open and nonjudgmental attitude. Empirical research is increasingly focusing on mindfulness as a dynamic and multifaceted state that can fluctuate across situations and time. The present study aimed to extend existing knowledge by using experience-sampling methodology to examine state-level mindfulness, pleasant/unpleasant event occurrence, and affective well-being in the everyday lives of middle-aged and older adults. A community-based sample of 157 participants aged 53-86 (M = 69.36, SD = 5.80) was recruited in May-June 2020. Participants completed assessments of multidimensional state mindfulness, hassle and uplift occurrence, and positive and negative affect on their smartphones, four times a day over 10 consecutive days. (Total observations: 4,761; M = 30.32, SD = 8.78.) Multilevel models indicated that the state mindfulness-facets present-moment attention and nonjudgmental acceptance were predictive of greater affective well-being in older adulthood. Furthermore, nonjudgmental acceptance appeared to buffer affective reactivity to daily hassles, and importantly, this effect was stronger at older ages. Mindful states did not appear to provide any further boost to uplift-related mood. The findings suggest that occasions characterized by relatively high present-moment attention and nonjudgmental acceptance may contribute to enhanced emotional well-being in later adulthood. Furthermore, adopting a nonevaluative and accepting orientation toward momentary experiences may be a psychological strategy that has particular utility for mitigating emotional reactivity to daily stressors with increasing age. Future research should investigate multidimensional state mindfulness and affective well-being for middle-aged and older adults participating in mindfulness-based interventions.

Understanding gender differences in human cognitive development may contribute to understanding the gender differences in outcomes in cognitive ageing. However, evaluation of this topic has been hindered by a lack of representative, longitudinal data from different aged cohorts measured on the same cognitive tests. Gender differences in cognitive abilities were evaluated in three population-based cohorts (baseline age-span 20 to 76, 52% female, 94% Caucasian, 5% Asian and 1% other ethnic background, baseline N = 7,485), initially drawn from the electoral role in Australia where voting is compulsory, that were assessed four times over 12 years on measures of verbal memory, processing speed, working memory, verbal ability, and reaction time. Linear mixed models showed that within each cohort, women had better verbal memory and men had better working memory and faster reaction times. Verbal ability and processing speed showed variable gender differences in the young and middle-aged cohorts but no difference in the oldest cohort. In young and middle age, there were no gender differences in rates of change in verbal memory, processing speed, reaction time, verbal ability, or working memory. In old age, the gender differences were only observed in rates of change in verbal memory. Women showed more verbal memory decline between the 8-year and 12-year follow-ups than men, despite retaining higher average memory performance than men. We conclude that from ages 20-76, gender differences in cognitive abilities are stable except for faster memory ageing among women in the eighth decade.

Introduction Mid-life dietary patterns are associated with Alzheimer's disease (AD) risk, although few controlled trials have been conducted. Methods Eighty-seven participants (age range: 45 to 65) with normal cognition (NC, n = 56) or mild cognitive impairment (MCI, n = 31) received isocaloric diets high or low in saturated fat, glycemic index, and sodium (Western-like/West-diet vs. Mediterranean-like/Med-diet) for 4 weeks. Diet effects on cerebrospinal fluid (CSF) biomarkers, cognition, and cerebral perfusion were assessed to determine whether responses differed by cognitive status. Results CSF amyloid beta (Aβ)42/40 ratios increased following the Med-diet, and decreased after West-diet for NC adults, whereas the MCI group showed the reverse pattern. For the MCI group, the West-diet reduced and the Med-diet increased total tau (t-tau), whereas CSF Aβ42 /t-tau ratios increased following the West-diet and decreased following the Med-diet. For NC participants, the Med-diet increased and the West-diet decreased cerebral perfusion. Discussion Diet response during middle age may highlight early pathophysiological processes that increase AD risk.

Objectives: A growing number of life course studies are examining the influence of earlier life experiences on morbidity, disability, and mortality in mid-old age.Method: Drawing from the social pathway model, this study expands the life course literature by utilizing data collected over 35 years from the National Longitudinal Survey of Youth, 1979 Cohort, spanning four life course phases (childhood, young adulthood, middle adulthood, and late-middle adulthood). Through structural equation analyses with a phantom model, we estimated depressive symptoms in late middle age as a result of pathway effects starting with childhood socio-economic status (SES) which effect young adulthood and middle adulthood. The multi-pathway life course model includes three potential mediators of middle adulthood: health risk behaviors, social activity, and negative life events.Results: We found limited support for a direct effect of childhood SES disadvantage on depressive symptoms in middle age. Instead, much of the effects of childhood SES on later-year depressive symptoms appear to be mediated by SES in young adulthood. Further, the long-term pathway is mediated through the influence of health risk behaviors and negative life events in middle adulthood.Conclusion: Our findings do not propose this chain is permanent and irreversible; rather, this study highlights the possibility that interventions focused on promoting health behaviors and improving living conditions for people from socioeconomically disadvantaged backgrounds could help reduce the instance of depression in middle age and health outcomes along the life course could be improved.

AIM Little is known about the link between obesity and loneliness as well as perceived social isolation. Therefore, the objective of this longitudinal study is to clarify whether the onset and the end of obesity is associated with changes in perceived social isolation as well as loneliness (stratified by sex) in older age. METHODS Longitudinal data were used from wave 5 (year 2014) and 6 (year 2017) of the German Ageing Survey - a nationally representative sample of community-dwelling individuals aged ≥40 years in Germany. Established tools were used to quantify loneliness and perceived social isolation. A body mass index ≥30 kg/m2 was used to classify individuals as being obese. Asymmetric fixed effects regressions were used. RESULTS Regressions showed that the end of obesity was associated with decreases in perceived social isolation among women (β = -0.24, P = 0.01), but not in men (with significant sex differences). The onset of obesity was not associated with changes in perceived social isolation. Neither the beginning of obesity nor the end of obesity was associated with changes in loneliness. CONCLUSIONS Our findings emphasize the importance of overcoming obesity for women in the second half of life. As most of the existing studies were conducted in Germany, studies from other countries are of importance to understand this association better. Geriatr Gerontol Int 2021; 21: 836-841.
