The silent epidemic of loneliness: identifying the antecedents of loneliness using a lagged exposure-wide approach.

BACKGROUND: A large and accumulating body of evidence shows that loneliness is detrimental for various health and well-being outcomes. However, less is known about potentially modifiable factors that lead to decreased loneliness. METHODS: We used data from the Health and Retirement Study to prospectively evaluate a wide array of candidate predictors of subsequent loneliness. Importantly, we examined if changes in 69 physical-, behavioral-, and psychosocial-health factors (from t0;2006/2008 to t1;2010/2012) were associated with subsequent loneliness 4 years later (t2;2014/2016). RESULTS: Adjusting for a large range of covariates, changes in certain health behaviors (e.g. increased physical activity), physical health factors (e.g. fewer functioning limitations), psychological factors (e.g. increased purpose in life, decreased depression), and social factors (e.g. greater number of close friends) were associated with less subsequent loneliness. CONCLUSIONS: Our findings suggest that subjective ratings of physical and psychological health and perceived social environment (e.g. chronic pain, self-rated health, purpose in life, anxiety, neighborhood cohesion) are more strongly associated with subsequent loneliness. Yet, objective ratings (e.g. specific chronic health conditions, living status) show less evidence of associations with subsequent loneliness. The current study identified potentially modifiable predictors of subsequent loneliness that may be important targets for interventions aimed at reducing loneliness.

Who Benefits From Helping? Moderators of the Association Between Informal Helping and Mortality.

BACKGROUND: While informal helping has been linked to a reduced risk of mortality, it remains unclear if this association persists across different levels of key social structural moderators. PURPOSE: To examine whether the longitudinal association between informal helping and all-cause mortality differs by specific social structural moderators (including age, gender, race/ethnicity, wealth, income, and education) in a large, prospective, national, and diverse sample of older U.S. adults. METHODS: We analyzed data from the Health and Retirement Study, a national sample of U.S. adults aged >50 (N = 9,662). Using multivariable Poisson regression, we assessed effect modification by six social structural moderators (age, gender, race/ethnicity, wealth, income, and education) for the informal helping (2006/2008) to mortality (2010-2016/2012-2018) association on the additive and multiplicative scales. RESULTS: Participants who reported ≥100 hr/year of informal helping (vs. 0 hr/year), had a lower mortality risk. Those who engaged in 1-49 hr/year most consistently displayed lower mortality risk across moderators, while those who engaged in 50-99 and ≥100 hr/year only showed decreased mortality risk across some moderators. When formally testing effect modification, there was evidence that the informal helping-mortality associations were stronger among women and the wealthiest. CONCLUSIONS: Informal helping is associated with decreased mortality. Yet, there appear to be key differences in who benefits from higher amounts of informal helping across social structural moderators. Further research is needed to evaluate how the associations between informal helping and health and well-being are patterned across key social structural moderators.

Informal helping has been associated with a decreased mortality risk, but it remains unclear if this association persists across different levels of key social structural moderators. We examined whether the longitudinal association between informal helping and all-cause mortality differs across age, gender, race/ethnicity, wealth, income, and education, in a large sample of older U.S. adults from the Health and Retirement Study (N = 9,662). Participants who reported ≥100 hr/year of informal helping (vs. 0 hr/year), had a lower mortality risk. Those who engaged in 1­49 hr/year most consistently displayed lower mortality risk across moderators, while those who engaged in 50­99 and ≥100 hr/year only showed decreased mortality risk across some moderators. There was evidence that the informal helping­mortality associations were stronger among women and the wealthiest when testing effect modification. While informal helping was associated with decreased mortality, there appear to be key differences in who benefits from higher amounts of informal helping across social structural moderators. Further research is needed to evaluate how the associations between informal helping and health and well-being differ across important social structural factors.

Informal Helping and Subsequent Health and Well-Being in Older U.S. Adults.

BACKGROUND: Growing evidence suggests that informal helping (unpaid volunteering not coordinated by an organization or institution) is associated with improved health and well-being outcomes. However, studies have not investigated whether changes in informal helping are associated with subsequent health and well-being. METHODS: This study evaluated if changes in informal helping (between t0;2006/2008 and t1;2010/2012) were associated with 35 indicators of physical, behavioral, and psychosocial health and well-being (at t2;2014/2016) using data from 12,998 participants in the Health and Retirement study - a national cohort of US adults aged > 50. RESULTS: Over the four-year follow-up period, informal helping ≥ 100 (versus 0) hours/year was associated with a 32% lower mortality risk (95% CI [0.54, 0.86]), and improved physical health (e.g., 20% reduced risk of stroke (95% CI [0.65, 0.98])), health behaviors (e.g., 11% increased likelihood of frequent physical activity (95% CI [1.04, 1.20])), and psychosocial outcomes (e.g., higher purpose in life (ß = 0.15, 95% CI [0.07, 0.22])). However, there was little evidence of associations with various other outcomes. In secondary analyses, this study adjusted for formal volunteering and a variety of social factors (e.g., social network factors, receiving social support, and social participation) and results were largely unchanged. CONCLUSIONS: Encouraging informal helping may improve various aspects of individuals' health and well-being and also promote societal well-being.

Are all domains of life satisfaction equal? Differential associations with health and well-being in older adults.

PURPOSE: Growing evidence documents strong associations between overall life satisfaction and favorable health and well-being outcomes. However, because most previous studies have assessed satisfaction with one's life as a whole, we know little about whether specific domains of life satisfaction (e.g., satisfaction with family life, income) might be responsible for longitudinally driving better health and well-being. METHODS: Data were from 13,752 participants in the Health and Retirement Study-a prospective and nationally representative cohort of US adults aged > 50. We evaluated if positive changes in seven individual domains of life satisfaction (between t0; 2008/2010 and t1; 2012/2014) were associated with 35 indicators of physical, behavioral, and psychosocial health and well-being (at t2; 2016/2018). RESULTS: Most domains of life satisfaction were associated with psychological outcomes: satisfaction with family and non-work activities showed the largest associations (sometimes double in magnitude) with subsequent psychological factors, followed by satisfaction with financial situation and income. Further, some domains showed associations with specific physical health outcomes (e.g., mortality, number of chronic conditions, physical functioning limitations), health behaviors (e.g., sleep problems), and social factors (e.g., loneliness). CONCLUSIONS: As countries seek innovative and cost-effective methods of enhancing the health and well-being of our rapidly aging populations, findings from our study suggest that some domains of life satisfaction have a substantially larger influence on health and well-being outcomes than others. Individual domains of life satisfaction might be novel targets for interventions and policies seeking to enhance specific facets of health and well-being.

Early-life stress, depressive symptoms, and inflammation: the role of social factors.

OBJECTIVE: To identify modifiable, social factors that moderate the relationship between early-life stress (ELS) and health outcomes as measured by depressive symptoms and inflammation. METHODS: Data were from 3,416 adults (58.28% female), ages 36 - 97 (Mage = 68.41; SDage = 10.24) who participated in the 2006 wave of the Health and Retirement Study, a nationally representative sample of older adults in the United States. This study used hierarchical regression analyses to first test the main effects of ELS on depressive symptoms and inflammation (high-sensitivity C-reactive protein). Four social factors (perceived support, frequency of social contact, network size, and volunteer activity) were assessed as moderators of the ELS-depression and ELS-inflammation relationships. RESULTS: There was a small, positive association between ELS and depressive symptoms (B = 0.17, SE = 0.05, p = .002), which was moderated by social contact and perceived support. Specifically, ELS was only associated with elevated depressive symptoms for participants with limited social contact (B = 0.24, SE = 0.07, p < .001) and low perceived support (B = 0.24, SE = 0.07, p < .001). These associations remained after accounting for potential confounds (age, body-mass index, adulthood stress, and marital status). CONCLUSIONS: Increased social contact and perceived support may be protective for individuals at a higher risk of developing depressive symptoms as a result of ELS. Future interventions may benefit from leveraging these social factors to improve quality of life in adults with ELS.

The positive influence of sense of control on physical, behavioral, and psychosocial health in older adults: An outcome-wide approach.

Accumulating research indicates robust associations between sense of control and salutary health and well-being outcomes. However, whether change in sense of control is associated with subsequent outcomes has been under-evaluated. Participants (N = 12,998) were from the Health and Retirement Study-a diverse, nationally representative, and longitudinal sample of U.S. adults aged >50 years. We examined how increase in sense of control (from t0:2006/2008 to t1: 2010/2012) was associated with better outcomes on 35 indicators of: physical-, behavioral-, and psychosocial-health (t2:2014/2016). We used multiple logistic-, linear-, and generalized-linear regression models and controlled for sociodemographic characteristics, personality traits, sense of control, and all outcomes in the pre-baseline wave (t0:2006/2008). During the 4-year follow-up, people in the highest (vs. lowest) quartile of sense of control, conditional on prior sense of control, had reduced risk of mortality and improved physical-health outcomes (lower risk of: stroke, lung disease, physical limitations, cognitive impairment, chronic pain and higher self-rated health). Sense of control was related to better health-behaviors (increased physical activity, reduced sleep problems), higher psychological well-being (positive affect, life satisfaction, optimism, purpose, personal-, health-, financial-mastery), lower psychological distress (depression, hopelessness, negative affect, perceived constraints), decreased loneliness, and increased contact with friends. Sense of control was unrelated to other physical health indicators (diabetes, hypertension, heart disease, cancer, arthritis, overweight/obesity), health behaviors (binge drinking, smoking), and social factors (living with spouse/partner, frequency of contact with children and other family). These findings underscore the importance of sense of control as a potential intervention target for fostering physical-, behavioral-, and psychosocial-health.

Volunteering in Young Adulthood: Complex Associations With Later Health and Well-Being Outcomes.

PURPOSE: To investigate whether changes in volunteering from adolescence to young adulthood are associated with subsequent health and well-being outcomes in adulthood. DESIGN: Longitudinal cohort study. SETTING: National Longitudinal Study of Adolescent to Adult Health. SUBJECTS: U.S. adults from Wave IV (2008/2009; N = 12,234) and Wave V (2016-2018; N = 9,971). MEASURES: Any volunteering and nine types of volunteering (independent variables) and 41 health and well-being outcomes (dependent variables) using an outcome-wide approach with multiple linear-, logistic-, and generalized linear regressions. RESULTS: Volunteering in young adulthood was associated with better health behaviors (e.g., 34% decreased risk of binge drinking, 95% CI [0.54, 0.81]) and improved psychosocial and civic outcomes (e.g., lower depressive symptoms (ß = -0.08, 95% CI [-0.14, -0.02]) in adulthood. Volunteering showed little evidence of associations with other health and well-being outcomes (e.g., loneliness, (ß = -0.04, 95% CI [-0.09, 0.01])). Assessing volunteering by organization types showed a range of positive and negative outcomes. For example, volunteering in hospitals/nursing homes was associated with a 36% increased risk of high cholesterol (95% CI [1.06, 1.73]) and volunteering with political clubs was associated with a 52% increased risk of an anxiety diagnosis (95% CI [1.13, 2.05]). CONCLUSION: Our findings suggest more work is needed to determine the conditions under which volunteering is health promoting and to minimize potential adverse effects associated with some types of volunteering.

Reduced Epigenetic Age in Older Adults With High Sense of Purpose in Life.

Psychosocial risk factors have been linked with accelerated epigenetic aging, but little is known about whether psychosocial resilience factors (eg, Sense of Purpose in Life) might reduce epigenetic age acceleration. In this study, we tested if older adults who experience high levels of Purpose might show reduced epigenetic age acceleration. We evaluated the relationship between Purpose and epigenetic age acceleration as measured by 13 DNA methylation (DNAm) "epigenetic clocks" assessed in 1 572 older adults from the Health and Retirement Study (mean age 70 years). We quantified the total association between Purpose and DNAm age acceleration as well as the extent to which that total association might be attributable to demographic factors, chronic disease, other psychosocial variables (eg, positive affect), and health-related behaviors (heavy drinking, smoking, physical activity, and body mass index [BMI]). Purpose in Life was associated with reduced epigenetic age acceleration across 4 "second-generation" DNAm clocks optimized for predicting health and longevity (false discovery rate [FDR] q < 0.0001: PhenoAge, GrimAge, Zhang epigenetic mortality index; FDR q < 0.05: DunedinPoAm). These associations were independent of demographic and psychosocial factors, but substantially attenuated after adjusting for health-related behaviors (drinking, smoking, physical activity, and BMI). Purpose showed no significant association with 9 "first-generation" DNAm epigenetic clocks trained on chronological age. Older adults with greater Purpose in Life show "younger" DNAm epigenetic age acceleration. These results may be due in part to associated differences in health-related behaviors. Results suggest new opportunities to reduce biological age acceleration by enhancing Purpose and its behavioral sequelae in late adulthood.

Reduced epigenetic age in older adults who volunteer.

BACKGROUND: Volunteering is associated with improved health and well-being outcomes, including a reduced risk of mortality. However, the biological mechanisms underlying the association between volunteering and healthy aging and longevity have not been well-established. We evaluated if volunteering was associated with reduced epigenetic age acceleration in older adults. METHODS: We evaluated associations between volunteering and age acceleration, measured by 13 DNA methylation (DNAm) "epigenetic clocks" in 4011 older adults (Mage=69 years; SDage=10 years) who participated in the Health and Retirement Study. We assessed 9 first-generation clocks (Horvath, Hannum, Horvath Skin, Lin, Garagnani, Vidalbralo, Weidner, Yang, and Bocklandt, which predict chronological age) and 4 second-generation clocks (Zhang, PhenoAge, GrimAge, and DunedinPoAm, which predict future disease or longevity). We quantified the total associations between volunteering and DNAm age acceleration as well as the extent to which these associations might be attributable to potential confounding by individual demographics (e.g., race), social demographics (e.g., income), health factors (e.g., diabetes), and health behaviors (e.g., smoking). RESULTS: Volunteering was associated with reduced epigenetic age acceleration across 6 epigenetic clocks optimized for predicting health and longevity (False Discovery Rate [FDR] q < 0.0001 for epigenetic clocks: PhenoAge, GrimAge, DunedinPoAm, Zhang mortality, Yang mitotic; FDR q < 0.01: Hannum). These associations were mostly independent of demographic and health factors, but substantially attenuated after adjusting for health behaviors. CONCLUSION: Volunteering was associated with reduced epigenetic age acceleration in 6 of 13 (mostly second-generation) epigenetic clocks. Results provide preliminary evidence that volunteering might provide health benefits through slower biological aging and implicate health behaviors as one potential mechanism of such effects.

Are loneliness and social isolation equal threats to health and well-being? An outcome-wide longitudinal approach.

The detrimental effects of loneliness and social isolation on health and well-being outcomes are well documented. In response, governments, corporations, and community-based organizations have begun leveraging tools to create interventions and policies aimed at reducing loneliness and social isolation at scale. However, these efforts are frequently hampered by a key knowledge gap: when attempting to improve specific health and well-being outcomes, decision-makers are often unsure whether to target loneliness, social isolation, or both. Filling this knowledge gap will inform the development and refinement of effective interventions. Using data from the Health and Retirement Study (13,752 participants (59% women and 41% men, mean [SD] age = 67 [10] years)), we examined how changes in loneliness and social isolation over a 4-year follow-up period (from t0:2008/2010 to t1:2012/2014) were associated with 32 indicators of physical-, behavioral-, and psychosocial-health outcomes 4-years later (t2:2016/2018). We used multiple logistic-, linear-, and generalized-linear regression models, and adjusted for sociodemographic, personality traits, pre-baseline levels of both exposures (loneliness and social isolation), and all outcomes (t0:2008/2010). We incorporated data from all participants into the overall estimate, regardless of whether their levels of loneliness and social isolation changed from the pre-baseline to baseline waves. After adjusting for a wide range of covariates, we observed that both loneliness and social isolation were associated with several physical health outcomes and health behaviors. However, social isolation was more predictive of mortality risk and loneliness was a stronger predictor of psychological outcomes. Loneliness and social isolation have independent effects on various health and well-being outcomes and thus constitute distinct targets for interventions aimed at improving population health and well-being.

What makes life purposeful? Identifying the antecedents of a sense of purpose in life using a lagged exposure-wide approach.

Aims: Prior research documents strong associations between an increased sense of purpose in life and improved health and well-being outcomes. However, less is known about candidate antecedents that lead to more purpose among older adults. Methods: We used data from 13,771 participants in the Health and Retirement Study (HRS) - a diverse, national panel study of adults aged >50 in the United States, to evaluate a large number of candidate predictors of purpose. Specifically, using linear regression with a lagged exposure-wide approach, we evaluated if changes in 61 predictors spanning physical health, health behaviors, and psychosocial well-being (between t0;2006/2008 and t1;2010/2012) were associated with purpose four years later (t2;2014/2016) after adjustment for a rich set of baseline covariates. Results: Some health behaviors (e.g., physical activity ≥1x/week [ß = 0.14, 95% CI: 0.09, 0.19]), physical health conditions (e.g., stroke [ß = -0.25, 95% CI: -0.40, -0.10]), and psychosocial factors (e.g., depression [ß = -0.21, 95% CI: -0.27, -0.15]) were associated with subsequent purpose four years later. However, there was little evidence that other health behaviors, physical health conditions, and psychosocial factors such as smoking, drinking, or financial strain, were associated with subsequent purpose. Conclusions: Several of our candidate predictors such as volunteering, time with friends, and physical activity may be important targets for interventions and policies aiming to increase purpose among older adults. However, some effect sizes were modest and contrast with prior work on younger populations, suggesting purpose may be more easily formed earlier in life.

Pathways to reduced overnight hospitalizations in older adults: Evaluating 62 physical, behavioral, and psychosocial factors.

As our society ages and healthcare costs escalate, researchers and policymakers urgently seek potentially modifiable predictors of reduced healthcare utilization. We aimed to determine whether changes in 62 candidate predictors were associated with reduced frequency, and duration, of overnight hospitalizations. We used data from 11,374 participants in the Health and Retirement Study-a national sample of adults aged >50 in the United States. Using generalized linear regression models with a lagged exposure-wide approach, we evaluated if changes in 62 predictors over four years (between t0;2006/2008 and t1;2010/2012) were associated with subsequent hospitalizations during the two years prior to t2 (2012-2014 (Cohort A) or 2014-2016 (Cohort B)). After robust covariate-adjustment, we observed that changes in some health behaviors (e.g., those engaging in frequent physical activity had 0.80 the rate of overnight hospital stays (95% CI [0.74, 0.87])), physical health conditions (e.g., those with cancer had 1.57 the rate of overnight hospital stays (95% CI [1.35, 1.82])), and psychosocial factors (e.g., those who helped friends/neighbors/relatives 100-199 hours/year had 0.73 the rate of overnight hospital stays (95% CI [0.63, 0.85])) were associated with subsequent hospitalizations. Findings for both the frequency, and duration, of hospitalizations were mostly similar. Changes in a number of diverse factors were associated with decreased frequency, and duration, of overnight hospitalizations. Notably, some psychosocial factors (e.g., informal helping) had effect sizes equivalent to or larger than some physical health conditions (e.g., diabetes) and health behaviors (e.g., smoking). These psychosocial factors are mostly modifiable and with further research could be novel intervention targets for reducing hospitalizations.

Sense of Purpose in Life and Subsequent Physical, Behavioral, and Psychosocial Health: An Outcome-Wide Approach.

PURPOSE: Growing evidence indicates that a higher sense of purpose in life (purpose) is associated with reduced risk of chronic diseases and mortality. However, epidemiological studies have not evaluated if change in purpose is associated with subsequent health and well-being outcomes. DESIGN: We evaluated if positive change in purpose (between t0; 2006/2008 and t1;2010/2012) was associated with better outcomes on 35 indicators of physical health, health behaviors, and psychosocial well-being (at t2;2014/2016). SAMPLE: We used data from 12,998 participants in the Health and Retirement study-a prospective and nationally representative cohort of U.S. adults aged >50. ANALYSIS: We conducted multiple linear-, logistic-, and generalized linear regressions. RESULTS: Over the 4-year follow-up period, people with the highest (versus lowest) purpose had better subsequent physical health outcomes (e.g., 46% reduced risk of mortality (95% CI [0.44, 0.66])), health behaviors (e.g., 13% reduced risk of sleep problems (95% CI [0.77, 0.99])), and psychosocial outcomes (e.g., higher optimism (ß = 0.41, 95% CI [0.35, 0.47]), 43% reduced risk of depression (95% CI [0.46, 0.69]), lower loneliness (ß = -0.35, 95% CI [-0.41, -0.29])). Importantly, however, purpose was not associated with other physical health outcomes, health behaviors, and social factors. CONCLUSION: With further research, these results suggest that sense of purpose might be a valuable target for innovative policy and intervention work aimed at improving health and well-being.

Identifying pathways to religious service attendance among older adults: A lagged exposure-wide analysis.

We used prospective data (spanning 8 years) from a national sample of older U.S. adults aged > 50 years (the Health and Retirement Study, N = 13,771) to evaluate potential factors that lead to subsequent religious service attendance. We applied a lagged exposure-wide epidemiologic design and evaluated 60 candidate predictors of regular subsequent religious service attendance. Candidate predictors were drawn from the following domains: health behaviors, physical health, psychological well-being, psychological distress, social factors, and work. After rigorous adjustment for a rich set of potential confounders, we observed modest evidence that changes in some indices of physical health, psychological well-being, psychological distress, and social functioning predicted regular religious service attendance four years later. Our findings suggest that there may be opportunities to support more regular religious service attendance among older adults who positively self-identify with a religious/spiritual tradition (e.g., aid services for those with functional limitations, psychological interventions to increase hope), which could have downstream benefits for various dimensions of well-being in the later years of life.

Identifying pathways to increased volunteering in older US adults.

While growing evidence documents strong associations between volunteering and improved health and well-being outcomes, less is known about the health and well-being factors that lead to increased volunteering. Using data from 13,771 participants in the Health and Retirement Study (HRS)-a diverse, longitudinal, and national sample of older adults in the United States-we evaluated a large range of candidate predictors of volunteering. Specifically, using generalized linear regression models with a lagged exposure-wide approach, we evaluated if changes in 61 predictors spanning physical health, health behaviors, and psychosocial well-being (over a 4-year follow-up between t0; 2006/2008 and t1; 2010/2012) were associated with volunteer activity four years later (t2; 2014/2016). After adjusting for a rich set of covariates, certain changes in some health behaviors (e.g., physical activity ≥ 1x/week), physical health conditions (e.g., physical functioning limitations, cognitive impairment), and psychosocial factors (e.g., purpose in life, constraints, contact with friends, etc.) were associated with increased volunteering four years later. However, there was little evidence that other factors were associated with subsequent volunteering. Changes in several indicators of physical health, health behaviors, and psychosocial well-being may predict increased volunteering, and these factors may be novel targets for interventions and policies aiming to increase volunteering in older adults.

Associations Between Satisfaction With Aging and Health and Well-being Outcomes Among Older US Adults.

Importance: Researchers and policy makers are expanding the focus from risk factors of disease to seek potentially modifiable health factors that enhance people's health and well-being. Understanding if and to what degree aging satisfaction (one's beliefs about their own aging) is associated with a range of health and well-being outcomes aligns with the interests of older adults, researchers, health systems, and politicians. Objectives: To evaluate associations between changes in aging satisfaction and 35 subsequent health and well-being outcomes. Design, Setting, and Participants: This cohort study used data from the Health and Retirement Study, a national, diverse, and longitudinal sample of 13 752 US adults older than 50 years, to evaluate if changes in aging satisfaction (between combined cohorts from 2008 and 2010 and 4 years later, in 2012 and 2014) were subsequently associated with 35 indicators of physical, behavioral, and psychosocial health and well-being in 2016 and 2018. Statistical analysis was conducted from July 24, 2020, to November 6, 2021. Exposure: Aging satisfaction. Main Outcomes and Measures: A total of 35 physical (eg, stroke), behavioral (eg, sleep problems), and psychosocial (eg, depression) outcomes were evaluated using multiple linear and generalized linear regression models. Data from all participants, irrespective of how their levels of aging satisfaction changed from the prebaseline to baseline waves, were incorporated into the overall estimate, which was conditional on prior satisfaction. Results: During the 4-year follow-up period, participants (N = 13 752; 8120 women [59%]; mean [SD] age, 65 [10] years; median age, 64 years [IQR, 56-72 years]; 7507 of 11 824 married [64%]) in the highest (vs lowest) quartile of aging satisfaction had improved physical health (eg, 43% reduced risk of mortality [risk ratio, 0.57; 95% CI, 0.46-0.71]), better health behaviors (eg, 23% increased likelihood of frequent physical activity [risk ratio, 1.23; 95% CI, 1.12-1.34]), and improved psychosocial well-being (eg, higher positive affect [ß = 0.51; 95% CI, 0.44-0.58] and lower loneliness [ß = -0.41; 95% CI, -0.48 to -0.33]), conditional on prebaseline aging satisfaction. Conclusions and Relevance: This study suggests that higher aging satisfaction is associated with improved subsequent health and well-being. These findings highlight potential outcomes if scalable aging satisfaction interventions were developed and deployed at scale; they also inform the efforts of policy makers and interventionists who aim to enhance specific health and well-being outcomes. Aging satisfaction may be an important target for future interventions aiming to improve later-life health and well-being.
