Life satisfaction components and all-cause and cause-specific mortality: A large prospective cohort study. J Affect Disord 2024; 350:916-925. [PMID: 38244788 DOI: 10.1016/j.jad.2024.01.148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/10/2024] [Accepted: 01/14/2024] [Indexed: 01/22/2024]
Abstract
BACKGROUND Which life satisfaction components could be a target of positive psychological interventions for longevity is largely unknown. We aimed to investigate association of the composite measure of life satisfaction and its individual components with mortality. METHODS This cohort study included UK Biobank participants who responded to questions concerning five components of life satisfaction at baseline. We generated a composite score representing overall life satisfaction, ranging from 0 (lowest) to 5 (highest). The outcomes were all-cause and cause-specific mortality. We used multivariable Cox regression to estimate hazard ratios (HR) for the associations of interest. RESULTS Among 165,842 eligible participants, 12,261 all-cause deaths were observed over a median of 12.9-year follow-up. Overall life satisfaction was inversely associated with all-cause mortality (adjusted HR 0.94 [95% CI: 0.93-0.95] per 1 score increment). Health satisfaction showed the strongest association with all-cause mortality, with a fully adjusted HR of 0.52 (95% CI: 0.49-0.55) for high/extreme satisfaction and 0.63 (95% CI: 0.59-0.66) for moderate satisfaction, compared with unsatisfaction (P-trend<0.001), independent of other satisfaction components, regardless of physical health and sociodemographics. The association for family, friendship, work and financial satisfaction was attenuated when adjusted for other life satisfaction components. Similar findings were observed for cause-specific mortality. LIMITATIONS Observational study with single baseline measurement of life satisfaction precludes the ability to establish causal relationship. CONCLUSIONS Higher overall life satisfaction was associated with lower mortality. As the major contributor to lower mortality regardless of physical health and sociodemographics, health satisfaction could be an important target of positive psychological interventions for longevity.

Grip strength affects the association between platelet count and disability-free survival: Evidence from the China Health and Retirement Longitudinal Study. Arch Gerontol Geriatr 2023; 112:105026. [PMID: 37062186 DOI: 10.1016/j.archger.2023.105026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 04/01/2023] [Accepted: 04/10/2023] [Indexed: 04/18/2023]
Abstract
BACKGROUND AND AIMS Previous studies found elevated platelet count (PLT), especially long-term persist high or increased PLT was associated with less likelihood disability-free survival (DFS). However, whether grip strength affects the relationship between them is still not elucidated. METHODS A total of 6252 participants were recruited in the analysis based on the China Health and Retirement Longitudinal Study. The primary outcome was DFS, evaluated by a composite endpoint based on the first occurrence of either disability (having difficulty in at least one of the 6 activities of daily living: namely, dressing, bathing, continence, eating, getting into or out of bed, and toileting) or all-cause mortality. RESULTS The association of PLT with primary outcome was significantly modified by grip strength (pinteraction = 0.022). The rates of primary outcome were significantly lower among participants with lower baseline PLT in participants with normal grip strength (multivariable odds ratio [OR], 0.67; 95% confidence interval [CI], 0.54-0.84; ptrend < 0.001), but not in those with low grip strength (multivariable OR, 1.70; 95% CI, 0.88-3.15; ptrend = 0.135), for the lowest quartile vs the highest quartile. Adding baseline PLT (quartiles or continuous) to a model containing conventional risk factors significantly improved risk reclassification for primary outcome among those with normal grip strength (most of p < 0.05). CONCLUSION An inverse dose-response association of PLT with DFS was found among participants with normal grip strength, but not among those with low grip strength. Low grip strength might weaken the benefit of low PLT on DFS among middle-aged and older Chinese.

Front Psychiatry 2023; 14:1092971. [PMID: 37032944 PMCID: PMC10073436 DOI: 10.3389/fpsyt.2023.1092971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Accepted: 02/27/2023] [Indexed: 04/11/2023] Open
Abstract
Background Although a significant amount of literature has examined the association between childhood adversity and adverse health outcomes, which may be affected by sleep duration and life satisfaction. However, this relationship has not been researched in the Chinese population. This study aimed to assess the association between childhood adversity and health outcomes, with sleep duration and life satisfaction as mediators. Methods A total of 14,693 subjects aged 45 and over from the 2018 China Health and Retirement Longitudinal Study (CHARLS) were included. Taking childhood adversity as the independent variable, the health level of middle-aged and older individuals as the dependent variable, and sleep time and satisfaction as the mediating factors, Mplus 8.0 software was used to establish a structural equation model (SEM) to analyze the link between childhood adversity and health level and to explore the mediating effect of target mediators between childhood adversity and health level. Results In this study, childhood adversity was positively associated with depression symptoms, activities of daily living (ADL), and the number of chronic diseases (r = 0.116, 0.026 and 0.050, respectively, P < 0.001). Associations between adverse childhood experiences (ACEs) and depressive symptoms, ADL, and number of chronic diseases were mediated by sleep duration and life satisfaction, respectively. Conclusion Adversity experienced in childhood can affect the health status of middle-aged and older people. By ensuring adequate sleep and improving life satisfaction, health outcomes can be improved, and the negative effects of childhood adversity can be reduced.

Abstract
OBJECTIVES The aim of the study was to investigate the association between mental symptoms and incident functional disability among middle-age and older adults in South Africa. METHODS Longitudinal data from two consecutive population surveys (2014/2015-2018/2019) in Agincourt, South Africa, were analysed. RESULTS In total, 298 of 3813 participants without functional disability in wave 1 (8.8%) had functional disability in wave 2. The prevalence of baseline functional disability was 9.1%. In the fully adjusted models for people without functional disability at baseline, depressive symptoms (AOR: 1.74, 95% CI: 1.08-2.80) among men and lower life satisfaction among men (AOR: 0.86, 95% CI: 0.80-0.93) and among women (AOR: 0.90, 95% CI: 0.83-0.98) increased the odds of incident functional disability. Posttraumatic stress disorder symptoms, poor sleep quality, restless sleep, and loneliness were not significantly associated with incident functional disability. CONCLUSIONS Depressive symptoms among men and lower life satisfaction among both sexes were independently associated with incident functional disability in ageing rural South Africans.

Abstract
Background This study examines correlates of disabilities related to ADL, IADL, mobility, and frailty in men and women with a nationally representative sample of older adults living in the community. Methods A total of 10,898 noninstitutionalized Taiwanese nationals aged 65 years and older enrolled in the 2001 (N = 2,064), 2005 (N = 2,727), 2009 (N = 2,904), and 2013 (N = 3,203) National Health Interview Survey (NHIS) were analyzed. Results The prevalence of mobility disabilities and frailty in older adults in Taiwan decreased during the past decade (\documentclass[12pt]{minimal}

Exercise, social engagement, and tea and coffee intake were found to be associated with lower levels of all types of disabilities in both men and women. In addition, a diet based on carbohydrates, falls, depressive symptomatology, lung and metabolic diseases were risks for most of the disabilities under consideration. Gender-specific independent correlates included: being married (OR = 0.63, 95%CI: 0.40–0.98), eggs/beans/fish/meat consumption (OR = 0.35, 95% CI = 0.16–0.80); depressive symptoms, obesity and cataracts, which were associated with higher IADL (OR = 3.61, 1.63, and 1.18, respectively) and frailty limitations (OR = 10.89, 1.27, and 1.20, respectively) in women. Cognitive impairment was found to be an important correlate for ADL limitations in men (OR = 3.64, 95%CI: 2.38–5.57). Conclusions Exercise, social participation and diet (more tea and coffee intake and lower carbohydrates) were correlates for lower levels of disability. Some gender-specific correlates were also identified, including associations of disability with depressive symptoms, obesity, and cataracts that were more distinct in women, and lower levels of disability which were especially significant in men who were married, eat more eggs, beans, fish, and meat, and those free from cognitive impairment.
