Restricted linear association between night sleep duration and diabetes risk in middle-aged and older adults: a 7-year follow-up analysis from the China health and retirement longitudinal study.

Background: A rapid increase in the prevalence of diabetes is an urgent public health concern among older adults, especially in developing countries such as China. Despite several studies on lifestyle factors causing diabetes, sleep, a key contributor, is understudied. Our study investigates the association between night sleep duration and diabetes onset over a 7-year follow-up to fill information gaps. Method: A population-based cohort study with 5437 respondents used 2011-2018 China Health and Retirement Longitudinal Study data. Using self-reported night sleep duration from the 2011 baseline survey, information on new-onset diabetes was collected in follow-up surveys. Baseline characteristics of participants with vs. without new-onset diabetes were compared using Chi-square and Mann-Whitney U tests. Multivariable Cox regression models estimated the independent relationship between night sleep and new-onset diabetes. The addictive Cox regression model approach and piece-wise regression described the nonlinear relationship between night sleep and new-onset diabetes. Subgroup analysis was also performed by age, gender, body measurement index, dyslipidemia, drinking status, smoking, hypertension, and afternoon napping duration. Result: 549 respondents acquired diabetes during a median follow-up of 84 months. After controlling for confounders, night sleep duration was substantially linked with new-onset diabetes in the multivariable Cox regression model. The risk of diabetes is lower for respondents who sleep longer than 5 hours, except for those who sleep over 8 hours [5.1-6h Hazard ratios (HR) [95% confidence intervals (CI)] = 0.71 (0.55, 0.91); 6.1-7h HR = 0.69 (0.53, 0.89); 7.1-8h HR = 0.58 (0.45, 0.76)]. Nonlinear connections were delineated by significant inflection points at 3.5 and 7.5 hours, with a negative correlation observed only between these thresholds. With one hour more night sleep, the risk of diabetes drops 15%. BMI and dyslipidemia were identified as modifiers when only consider the stand linear effect of sleep duration on diabetes. Conclusion: This study establishes a robust association between night sleep and new-onset diabetes in middle-aged and older Chinese individuals within the 3.5-7.5-hour range, offering a foundation for early glycemic management interventions in this demographic. The findings also underscore the pivotal role of moderate night sleep in preventing diabetes, marking a crucial juncture in community medical research.

A meta-narrative review of research traditions on hidden workers in aging population for transdisciplinary implementation research.

Hidden workers are defined as the three vulnerable subgroups of workers: the underemployed, the unemployed, and the discouraged workers. Hidden workers indeed the group with multiple identities; a transitioning retiree, jobseeker, caring for some, who may also have long term health conditions and ethnic minority all at the same time. Designing an intervention for this group necessitates the transdisciplinary knowledge. Transdisciplinary knowledge is crucial because it can inform how the intersectoral challenges might be addressed in interventions, and how the intersectoral implementation design and evaluation on hidden workers might be designed. This paper maps the intellectual landscape of the hidden workers in aging population literature to identify key disciplinary research clusters; and to find out how those research clusters are investigating hidden workers. With the meta-narrative review methodology on studies retrieved from the Web of Science Core Collection, five research clusters were identified: (1) public health approaches to hidden workers, (2) welfare state and aging workforce, (3) older jobseekers, (4) life course perspective, (5) retirement transitions. Each research cluster focuses on different aspects of hidden workers, with varying research questions and rationales. These include conceptualising the determinants of the hidden workers in aging populations and the complex interrelation with public health. Furthermore, we suggest an analytical framework to allow for better understanding between the research traditions based on (1) the chosen socioecological level of analysis, (2) whether the research question is on the determinant for hidden workers or on the outcome of being hidden and (3) the chronosystem (early/middle/later life) timeframe of research question that is addressed. Through this study, we can identify the main issues faced by hidden workers among the older adults and the measures to address these issues as well as opening up a possibility for cross-sectoral policy responses.

Exploring determinants of flourishing: a comprehensive network analysis of retirees in Taiwan.

BACKGROUND: Human flourishing is an emerging concept, extending beyond the conventional boundaries of subjective well-being and evolving into a comprehensive capture of the diverse dimensions of human life within complex societal structures. Therefore, moving away from traditional approaches centered on the single latent construct, this study aims to explore the multiple aspects of human flourishing and the intricate interplay of their contributing factors. METHODS: Data were collected from the Health and Living Environments Survey of Taiwanese Retirees during 2023 (valid sample n = 1,111). Human flourishing was measured using the Secure Flourish Index developed by Harvard University, which includes 12 indicators: (1) life satisfaction, (2) happiness, (3) mental health, (4) physical health, (5) meaning in life, (6) sense of purpose, (7) promoting good, (8) delaying gratification, (9) content relationships, (10) satisfying relationships, (11) financial stability, and (12) material stability. A mixed graphical network analysis was employed to analyze the related determinants, divided into four groups: (a) sociodemographic factors, (b) physical functions and health status, (c) social and family engagement, and (d) community environmental characteristics as nodes. RESULTS: We analyzed 31 variables and identified 133 nonzero edges out of 465 potential connections in the comprehensive network. Results showed that happiness and promoting good were the two most critical indicators influencing retirees' overall flourishing. Different flourishing indicators were also associated with various influential factors. For instance, personal characteristics, especially gender and education, emerged as central factors. Family caregiving negatively affected happiness and financial stability, whereas social engagement was positively associated with life satisfaction and meaning in life. Employment status had mixed effects, negatively associated with life satisfaction but positively associated with mental health. Community environments, such as a sense of community and neighborhood safety, generally enhanced flourishing. However, the accessibility of neighborhood resources was paradoxically associated with material stability, pointing to the complexity of environmental factors in human flourishing. CONCLUSION: This study provides a comprehensive network analysis that reveals intricate connections between personal, behavioral, and environmental factors, offering profound insights for targeted interventions to foster human flourishing.

Nonlinear and threshold effects of built environment on older adults' walking duration: do age and retirement status matter?

Introduction: Walking plays a crucial role in promoting physical activity among older adults. Understanding how the built environment influences older adults' walking behavior is vital for promoting physical activity and healthy aging. Among voluminous literature investigating the environmental correlates of walking behaviors of older adults, few have focused on walking duration across different age groups and life stages, let alone examined the potential nonlinearities and thresholds of the built environment. Methods: This study employs travel diary from Zhongshan, China and the gradient boosting decision trees (GBDT) approach to disentangle the age and retirement status differences in the nonlinear and threshold effects of the built environment on older adults' walking duration. Results: The results showed built environment attributes collectively contribute 57.37% for predicting older adults' walking duration, with a higher predicting power for the old-old (70+ years) or the retired. The most influencing built environment attribute for the young-old (60-70 years) is bus stop density, whereas the relative importance of population density, bus stop density, and accessibility to green space or commercial facilities is close for the old-old. The retired tend to walk longer in denser-populated neighborhoods with better bus service, but the non-retired are more active in walking in mixed-developed environments with accessible commercial facilities. The thresholds of bus stop density to encourage walking among the young-old is 7.8 counts/km2, comparing to 6 counts/km2 among the old-old. Regarding the green space accessibility, the effective range for the non-retired (4 to 30%) is smaller than that of the retired (12 to 45%). Discussion: Overall, the findings provide nuanced and diverse interventions for creating walking-friendly neighborhoods to promote walking across different sub-groups of older adults.

How do patients perceive the retirement of their general practitioner? A qualitative interview study in France.

OBJECTIVES: The perspective of general practitioners' (GPs) on retirement and the factors influencing their attitude towards retirement have been previously investigated. However, while the number of GPs has been declining for many years in France, leading to the emergence of medical deserts, the impact on their patients remains to be explored. The aim of this study was to understand patients' perceptions of their GP's retirement. DESIGN: A semistructured interview-based qualitative study was conducted, using Interpretative Phenomenological Analysis. SETTING: Interviews were conducted in two general practices located in Essonne, Ile-de-France, France, between January and April 2014. PARTICIPANTS: Thirteen women and five men, aged 21-94 years, were included in this study. Exclusion criteria were the non-declaration of the physician as the declared doctor and being under 18 years of age. RESULTS: The GP-patient relationship is a link that is built up over time, over the course of several consultations. Patients choose their GP based on qualities or skills they value. In this way, the physician chosen is unique for their patients; this choice reflects a certain loyalty to their physician. The interaction with the family sphere reinforces this relationship through the multiple links created during care. When a GP retires, this link is broken. Patients' reactions can range from indifference to real grief. CONCLUSION: This study confirms the importance of the link between the GPs and their patients and highlights the need to prepare patients for their GP's retirement.

Physical activity dynamically moderates the impact of multimorbidity on the trajectory of healthy aging over sixteen years.

BACKGROUND: Research examining the healthy aging trajectory of retired older adults with multimorbidity is limited, leaving uncertainties regarding the optimal physical activity (PA) intensity and frequency necessary to sustain healthy aging during retirement. METHODS: Our study investigated the moderating effects of PA on the healthy aging trajectories of retired older adults living with multimorbidity in the United States (US). We utilized data from 1,238 retired individuals aged 50 to 102 who contributed 11,142 observations over 16 years from the Health and Retirement Study (HRS). We employed mixed effects modeling to assess the impact of various classes of multimorbidity on this group and examine how different PA, PA intensities, and PA frequencies influence the disability, physical, and cognitive functioning domains of healthy aging. RESULTS: The results reveal that while outcomes differed significantly, retired older adults in the US attained healthy aging at baseline. However, their ability to maintain healthy aging declined over time, with multimorbidity, especially musculoskeletal and neurological conditions, accelerating this decline. Fortunately, PA, especially light to moderate intensities, is associated with improving healthy aging and moderating the impact of multimorbidity on the disability and cognitive functioning domains of healthy aging. However, the specific moderating effects of PA depend on its frequency, intensity, and chronic conditions. CONCLUSIONS: The significant variability in healthy aging attainment among retired older adults underlies the need to consider these differences when addressing healthy aging issues in the US. Accounting for these variations would aid in evaluating the potential impact of future interventions and contribute to achieving health equity. Fortunately, our dynamic findings facilitate this objective by identifying specific frequencies and intensities of PA tailored to different aspects of multimorbidity and healthy aging. This highlights PA, especially light-to-moderate intensity, as an essential, cost-effective, and amenable strategy for alleviating the impact of multimorbidity on healthy aging.

Mental health status and influencing factors of retired teachers.

Introduction: The wellbeing of retired teachers is often easily overlooked. This study aims to explore the mental health status and influencing factors of retired teachers. Method: From October to December 2022, a convenient sampling survey was conducted on retired teachers using the Symptom Checklist 90 (SCL-90), mainly using the χ2-test and logistic regression analysis. Results: A sampling survey was conducted on 353 retired teachers, with an overall positive detection rate of 16.1%. The five factors with the highest positive detection rate were found to be obsessive-compulsive disorder (30.3%), interpersonal sensitivity (21.5%), paranoia (20.1%), anxiety (19.3%), and others (19.3%). The detection rates for the five factors, namely psychosis, depression, hostility, terror, and somatization, are all below 19%. The data on sex (χ2 = 4.626, P = 0.043), professional title (χ2 = 17.670, P = 0.003), income (χ2 = 9.960, P = 0.041), life satisfaction (χ2 = 27.348, P = 0.000), family relationships (χ2 = 51.451, P = 0.000), and physical health status (χ2 = 50.361, P = 0.000) show that the difference in mental health among retired teachers is statistically significant. The multivariate binary logistic regression analysis revealed that family relationships, life satisfaction, and physical health were important factors leading to mental health problems among retired teachers. Discussion: Retired teachers should cultivate a wide range of interests and hobbies, engage in regular physical exercise, develop healthy living habits, foster a positive family atmosphere, establish harmonious family relationships, promote community cultural construction, strengthen psychological intervention, and prevent psychological diseases.

Inflation, Economic Policy Changes, and Access to Essential Drugs by Retirees in Argentina.

This cross-sectional study investigates whether there are associations between inflation, economic policy changes, and retirees' access to medicines in Argentina.

The association between physical activity intensity and frailty risk among older adults across different age groups and genders: Evidence from four waves of the China Health and Retirement Longitudinal Survey.

"Exercise is the best medicine" is well known, but the optimal dose of physical activity (PA) for males and females across different age groups is still unknown. This study, using data from the four waves of CHARLS, aimed to determine the optimal PA dose that reduces frailty risks among older adults across various age groups and both sexes. We created a frailty index score using 63 health-related variables and used 0.21 as the frailty cut point. Binary logistic regression was used to compare the effect of vigorous, moderate, and light intensity PA under IPAQ criteria on frailty risk. The study found that regardless of whether males or females, the optimal effect of vigorous-intensity PA in reducing the risk of frailty is consistently observed throughout the entire old age career. Moreover, the age groups at which moderate-intensity PA reduces the risk of frailty were from age 70 for males and from age 80 for females. And light-intensity PA had no effect on reducing the risk of frailty. Moderate and vigorous intensity of PA in older adults should be promoted, but guidelines and recommendations must account for optimal associations with PA dose across genders and age groups.

The impact of retirement on blood pressure: evidence from a nationwide survey in China.

INTRODUCTION: The health impact of retirement is controversial. Most previous studies have been based on self-reported health indicators or the endpoints of some chronic diseases (e.g., morbidity or mortality), but objective physiological indicators (e.g., blood pressure) have rarely been used. The objective of this study is to elucidate the health effects of retirement on blood pressure, thereby offering empirical evidence to facilitate the health of retirees and to optimize retirement policies. METHODS: From 2012 to 2015, 84,696 participants of the Chinese Hypertension Survey (CHS) were included in this study. We applied the fuzzy regression discontinuity design (FRDD) to identify retirement's causal effect on systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure. We also explored the heterogeneity in the effects of retirement across different sex and education level groups. RESULTS: Based on the fully adjusted model, we estimated that retirement increased SBP by 5.047 mm Hg (95% CI: -2.628-12.723, P value: 0.197), DBP by 0.614 mm Hg (95% CI: -3.879-5.108, P value: 0.789) and pulse pressure by 4.433 mm Hg (95% CI: -0.985-9.851, P value: 0.109). We found that retirement led to a significant increase in male participants' SBP and pulse pressure as well as a possible decrease in female participants' blood pressure. Additionally, the blood pressure levels of low-educated participants were more vulnerable to the shock of retirement. CONCLUSION: Retirement is associated with an increase in blood pressure level. There is a causal relationship between the increase in blood pressure levels of men and retirement. Policy-makers should pay extra attention to the health status of men and less educated people when adjusting retirement policies in the future.

[Alcohol addiction and old age : state of the art]. / Alcoolodépendance et transition vers l'âge avancé : état des lieux.

The age of retirement until old age are driving on same important changes for physical health, mental health and decreasing social or working environment. The prevalence of alcohol addiction increases in this age group and is often underestimated by caregivers. Retirement is given as a risk factor to develop an alcohol addiction (late onset). It's also a worsening factor, when an alcohol addiction is already present (early onset). The consequences on physical health, mental health and psychosocial problems requires plural skills and coordination between the different stakeholders in the health, social and family sectors in order to find need- adapted solutions and treatments.

La phase de transition entre 55 ans et l'âge avancé amène de nombreux changements pour les personnes concernées, que ce soit au niveau psychique, physique ou socioprofessionnel. Dans le contexte du vieillissement de la population, les prises en charge des personnes souffrant de problèmes d'alcoolodépendance dans cette tranche d'âge prennent plus d'importance et sont souvent sous-estimées. Le passage à la retraite constitue un facteur de risque de développement d'une alcoolodépendance et un facteur d'aggravation quand celle-ci est déjà installée. L'intrication des problèmes (addictologiques, psychiques, somatiques, psychosociaux) exige des compétences plurielles et une coordination entre les différents intervenants des domaines de la santé, du social et de l'entourage familial afin de trouver des solutions adaptées aux besoins de la personne concernée.

Views of aging and mental health - The role of informal care provision: Longitudinal findings of the health and retirement study in the US.

BACKGROUND: Informal care is a common form of social support, which can vary greatly in its intensity. While views of aging have shown to be relevant to mental health before, we aim to analyze whether the association between views of aging and depressive symptoms is influenced by the provision of informal care and its intensity. METHODS: Data of six waves of the Health and Retirement Study in the United States was used. The sample includes up to 41,058 observations pooled over six waves of community-dwelling adults aged ≥50 years. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale (CESD) and attitudes towards own aging (ATOA) with the Philadelphia Geriatric Center Morale Scale (higher score indicates positive attitudes); informal caregiving (no/yes) and caregiving intensity (moderate, intense) were surveyed. Adjusted fixed effects regression analysis with robust standard errors, and with caregiving as moderator variable were calculated. RESULTS: Informal caregiving did not interact with ATOA. However, transitioning into intense caregiving significantly moderated the association between ATOA and depressive symptoms. Lower depressive symptoms were associated with better ATOA and this association was significantly stronger in the intense caregiving condition than in the non-caregiving condition. No significant interaction effects were found between any form of caregiving and subjective age. LIMITATIONS: The possibility of reciprocal effects cannot be excluded. CONCLUSION: Internalized ageism and depressive symptoms are more strongly related among caregivers who provide intense care. Thus, interventions to reduce internalized ageism could be helpful in particular among this vulnerable group of informal caregivers.

Association Between Socioeconomic Inequalities in Pain and All-Cause Mortality in the China Health and Retirement Longitudinal Study: Longitudinal Cohort Study.

BACKGROUND: Few studies focus on the equality of pain, and the relationship between pain and death is inconclusive. Investigating the distribution of pain and potential mortality risks is crucial for ameliorating painful conditions and devising targeted intervention measures. OBJECTIVE: Our study aimed to investigate the association between inequalities in pain and all-cause mortality in China. METHODS: Longitudinal cohort data from waves 1 and 2 of the China Health and Retirement Longitudinal Study (2011-2013) were used in this study. Pain was self-reported at baseline, and death information was obtained from the 2013 follow-up survey. The concentration index and its decomposition were used to explain the inequality of pain, and the association between pain and death was analyzed with a Cox proportional risk model. RESULTS: A total of 16,747 participants were included, with an average age of 59.57 (SD 9.82) years. The prevalence of pain was 32.54% (8196/16,747). Among participants with pain, the main pain type was moderate pain (1973/5426, 36.36%), and the common pain locations were the waist (3232/16,747, 19.3%), legs (2476/16,747, 14.78%) and head (2250/16,747, 13.44%). We found that the prevalence of pain was concentrated in participants with low economic status (concentration index -0.066, 95% CI -0.078 to -0.054). Educational level (36.49%), location (36.87%), and economic status (25.05%) contributed significantly to the inequality of pain. In addition, Cox regression showed that pain was associated with an increased risk of all-cause mortality (hazard ratio 1.30, 95% CI 1.06-1.61). CONCLUSIONS: The prevalence of pain in Chinese adults is concentrated among participants with low economic status, and pain increases the risk of all-cause death. Our results highlight the importance of socioeconomic factors in reducing deaths due to pain inequalities by implementing targeted interventions.

Trend analysis and influencing factors of healthy aging in middle-aged population in China: a longitudinal study based on the China Health and Retirement Longitudinal Study.

OBJECTIVES: This study aimed to assess the trends of healthy aging and investigate its determinants in the middle-aged population. STUDY DESIGN: This was a longitudinal study. METHODS: The sample comprised 3043 participants aged 45-59 years from the China Longitudinal Study of Health and Retirement 2011-2018. We plotted the prevalence across four waves and used ordered logistic models to investigate the determinants of cumulative times of healthy aging. RESULTS: We enrolled 3043 middle-aged people in our study. The prevalence of healthy aging is 28.2% at baseline but subsequently decreased to 19.72% at wave 4. Active socializing consistently ranked the lowest among the five dimensions. Participants with older age (odds ratio [OR] = 0.95, 95% confidence interval [CI] = 0.94-0.97), low monthly income (OR = 0.82, 95% CI: 0.69-0.97) or lived in urban (OR = 0.81, 95% CI: 0.70-0.94) were less likely to have per time increase in healthy aging. Participants with more than primary school degree (OR = 1.79, 95% CI: 1.31-2.46), high life satisfaction (OR = 2.38, 95% CI: 1.86-3.06), and good self-report health (OR = 1.97, 95% CI: 1.66-2.34) were more likely to have healthy aging. CONCLUSION: The number of middle-aged individuals in China who achieved healthy aging is declining and eventually less than one in five, which was far from ideal. Particular attention should be paid to older, women, urban dwellers, individuals with low income, low life satisfaction or poor self-report health. It is urgent to develop public health policies to improve the health and well-being of the middle-aged population.

Managing Career Transitions in Cardiothoracic Surgery.

Transitions during a career in cardiothoracic surgery include transition to practice following residency, multiple transitions over the course of the career, and transition to retirement. Each carries some degree of uncertainty and stress, and early preparation for each transition is key to success. A clear understanding of both professional and personal goals drives decisions and choices along the course of a career. It is crucial to seek legal counsel with expertise in physician employment contracts. Developing collegial and collaborative relationships should be a focus throughout one's career. This article outlines the key elements to successful career progression.

Bridge Employment or Encore Career? Examining Predictors That Distinguish Later-Life Career Transitions.

OBJECTIVES: Bridge employment and encore careers are 2 prevalent retirement pathways that have different goals and outcomes. Yet, "changing jobs in later life" is the shared prequel that blurs the distinction between them in empirical studies. This study proposes a set of criteria-voluntariness of career transition and the duration of work in the posttransition job-to distinguish various retirement pathways and investigates the predictors that distinguish the workers' choice of these pathways. METHODS: I conducted multinomial logistic regression to examine the predictors that distinguish between bridge employment, encore career, and direct workforce exit using the longitudinal sample of respondents with full-time career jobs in the Health and Retirement Study 1992-2020 (HRS, N = 2,038). To examine the predictors that distinguish between bridge employment and encore careers, I conducted logistic regression on the subsample of respondents who chose either bridge employment or encore careers (n = 927). RESULTS: The results show that the accumulated human capital from career jobs, physical and mental health conditions before leaving career jobs, and self-identified retirement status when transitioning to new jobs distinguish the workers' choices of taking on different retirement pathways. DISCUSSION: Maintaining the labor force participation of older workers is an important human resource agenda for policymakers. This study suggests that increasing the number of quality jobs for older workers would promote bridge employment and encore careers by raising the benefits of making career transitions as well as improving older workers' health.

Retirements of professional tennis players in second- and third-tier tournaments on the ATP and WTA tours.

The demands of professional tennis, including physical and psychological aspects, contribute to the frequency of retirements at elite levels of the sport. The aim of this study was to analyze epidemiological patterns and risk factors associated with retirements in previous ATP and WTA Tour tournaments. A retrospective cohort study was conducted. This study focused on previous ATP and WTA Tour tournaments. The ATP database encompassed 584,806 matches, while the WTA database included 267,380 matches. To assess retirements, potential risk factors such as playing surface, tournament category, match round, and player age were analyzed. Incidence rates were calculated for the period between 1978-2019 for men and 1994-2018 for women. The overall incidence rate was 1.56 (95%CI: 1.54, 1.59) and 1.36 (95%CI: 1.33, 1.39) retirements per 1000 games played in male and female competitions, respectively. Retirements increased over the years. Higher incidence rates were observed on hard (1.59 [95%CI: 1.56, 1.63] and 1.39 [95%CI: 1.34, 1.44]) and clay (1.60 [95%CI: 1.57, 1.63] and 1.36 [95%CI: 1.32, 1.41]) compared to grass courts (0.79 [95%CI: 0.65, 0.94] and 1.06 [95%CI: 0.88, 1.27]). Risk factors differed by gender, with tournament category significant in males (IRR: 1.23 [95%CI: 1.19, 1.28] in ITF vs ATP) and match round in females (IRR: 0.92 [95%CI: 0.88, 0.98] in preliminary vs final). This study provides valuable insights for coaches, players, support teams, and epidemiologists regarding retirements and associated risk factors in previous ATP and WTA Tour tournaments, contributing to injury prevention strategies.
