Correlates of subjective health in older adults: a meta-analysis

Unraveling the temporal interplay of slow-paced breathing and prefrontal transcranial direct current stimulation on cardiac indices of autonomic activity

The neurovisceral integration model proposes that information flows bidirectionally between the brain and the heart via the vagus nerve, indexed by vagally mediated heart rate variability (vmHRV). Voluntary reduction in breathing rate (slow-paced breathing, SPB, 5.5 Breathing Per Minute (BPM)) can enhance vmHRV. Additionally, prefrontal transcranial direct current stimulation (tDCS) can modulate the excitability of the prefrontal region and influence the vagus nerve. However, research on the combination of SPB and prefrontal tDCS to increase vmHRV and other cardiac (heart rate (HR) and blood pressure) and peripheral (skin conductance) indices is scarce. We hypothesized that the combination of 20 min of SPB and prefrontal tDCS would have a greater effect than each intervention in isolation. Hence, 200 participants were divided into four groups: active tDCS with SPB, active tDCS with 15 BPM breathing, sham tDCS with SPB, and sham tDCS with 15 BPM breathing. Regardless of the tDCS condition, the 5.5 BPM group showed a significant increase in vmHRV over 20 minutes and significant decreases in HR at the first and second 5-min epochs of the intervention. Regardless of breathing condition, the active tDCS group exhibited higher HR at the fourth 5-min epoch of the intervention than the sham tDCS group. No other effects were observed. Overall, SPB is a robust technique for increasing vmHRV, whereas prefrontal tDCS may produce effects that counteract those of SPB. More research is necessary to test whether and how SPB and neuromodulation approaches can be combined to improve cardiac vagal tone.

Age and Sex Differences in the Genetic Architecture of Measures of Subjective Health: Relationships With Physical Health, Depressive Symptoms, and Episodic Memory

OBJECTIVES

Subjective health (SH) is not just an indicator of physical health, but also reflects active cognitive processing of information about one's own health and has been associated with emotional health measures, such as neuroticism and depression. Behavior genetic approaches investigate the genetic architecture of SH, that is, genetic and environmental influences on individual differences in SH and associations with potential components such as physical, cognitive, and emotional health. Previous twin analyses have been limited by sex, sample size, age range, and focus on single covariates.

METHODS

The current analysis used data from 24,173 adults ranging in age from 40 to 90 years from the international Interplay of Genes and Environment across Multiple Studies consortium to investigate the genetic architecture of 3 measures of SH: self-rated health, health compared to others, and impact of health on activities. Independent pathways model of SH included physical health, depressive symptoms, and episodic memory, with age, sex, and country included as covariates.

RESULTS

Most or all of the genetic variance for SH measures were shared with physical health, depressive symptoms, and episodic memory. Genetic architecture of SH differed across measures, age groups (40-65, 66-90), and sexes. Age comparisons indicated stronger correlations with all 3 covariates in older adults, often resulting from greater shared genetic variance.

DISCUSSION

The predictive value of SH has been amply demonstrated. The higher genetic contributions to associations between SH and its components in older adults support the increasing conceptualization with age of SH as an intuitive summation of one's vital reserve.

Fuel poverty and mental health in a COVID-19 context

Fuel poverty is a widespread problem which affects people's health and has serious economic and social repercussions. Mental health has been adversely affected by the COVID-19 pandemic and appears to be particularly influenced by fuel poverty. We analyze this relationship while highlighting the unequal vulnerability of individuals in the population. We first built a novel database of 4194 representative observations of the French adult population. We then used a conditional mixed-process model to quantify the causal effect of fuel poverty on mental health using instrumental variables to overcome potential endogeneity. We prove the robustness of this causal effect by providing different sensitivity tests. Our results show that being fuel poor decreases the mental health score by 6.3 points out of 100. Fuel poverty also increases the depression score by 5.35 points, the anxiety score by 6.48 points, and decreases the social health score by 6.82 points. Our results show that tackling energy poverty can lead to positive spillover effects to improve mental health. Mitigation policies to provide energy-efficient housing should also become a priority to address climatic and economic hazards in the long term because they imply co-benefits in health.

A longitudinal study on self-rated health changes in disabled older people

There is a growing demand for quality healthcare for senior citizens among the disabled older population, considering their rising numbers. This study examines the longitudinal change in the health status of disabled older people and determines its effects on social exclusion and differences based on age at disability onset. The analysis was performed using a multilevel growth model on the health data for disabled older people (≥60 years) derived from the Korea Welfare Panel Study (KWePS). The following findings were observed based on the stated model: (1) The Self-Rated Health (SRH) of disabled older people increased over time, with significant individual differences in the initial status and growth rate; (2) The domains of economic and social network exclusion were associated with changes in the health status of disabled older people; and (3) The longitudinal effects of social exclusion on SRH changes in disabled older people varied according to the age at disability onset. Based on these results, strategies and implications for the development of health-promoting interventions for disabled older people were presented.

Daily general discrimination predicts changes in trait negative affectivity: A 30-year cohort longitudinal study using a random-intercept cross-lagged panel model

OBJECTIVE

Increasing evidence indicates discrimination is an emerging risk factor for reducing psychological well-being. Negative affectivity is a personality trait that has been associated with discrimination. Yet, few studies to date have examined the longitudinal relationship between discrimination and personality. The current study addresses this gap by examining how general discrimination and negative affectivity influence each other longitudinally.

METHOD

The Midlife in the United States (MIDUS) dataset was used for the current study. The MIDUS sample (N = 4244) was predominately white (90.7%), 52% female, and had an average age of 46 years old. Individuals completed follow-up measures 10 and 20 years after baseline. Data were analyzed using a random-intercept cross-lagged panel model.

RESULTS

Individuals that scored higher on trait negative affectivity also tended to score higher on perceived daily discrimination. We found general perceived discrimination at age 55 unidirectionally predicted changes in negative affectivity around retirement age, but not from age 45 to 55. In contrast, negative affectivity did not significantly predict increases in perceived discrimination at any timepoint.

CONCLUSION

Our results indicate that perceived discrimination has pernicious impacts on well-being up to a decade later and may do so by increasing an individual's tendency to experience negative emotions (i.e., negative affectivity).

Dementia and mortality in older adults: A twin study

INTRODUCTION

Dementia predicts increased mortality. We used case-control and co-twin control models to investigate genetic and shared environmental influences on this association.

METHODS

Case-control design, including 987 twins with dementia and 2938 age- and sex-matched controls in the Swedish Twin Registry. Co-twin control design, including 90 monozygotic (MZ) and 288 dizygotic (DZ) twin pairs discordant for dementia. To test for genetic and environmental confounding, differences were examined in mortality risk between twins with dementia and their matched or co-twin controls.

RESULTS

Twins with dementia showed greater mortality risk than age- and sex-matched controls (HR = 2.02 [1.86, 2.18]). Mortality risk is significantly elevated but attenuated substantially in discordant twin pairs, for example, comparing MZ twins with dementia to their co-twin controls (HR = 1.48 [1.08, 2.04]).

DISCUSSION

Findings suggest that genetic factors partially confound the association between dementia and mortality and provide an alternative hypothesis to increased mortality due to dementia itself. Highlights We studied dementia and mortality in twin pairs discordant for dementia. People without dementia outlived people with dementia. Identical twins with dementia and their co-twin controls had similar survival time. Findings suggest genotype may explain the link between dementia and mortality.

Negative work-to-family spillover stress and heightened cardiovascular risk biomarkers in midlife and older adults

OBJECTIVES

The current study aimed to investigate the health implications of negative work-to-family spillover on cardiovascular risk biomarkers.

METHODS

In a large-scale cross-sectional dataset of working or self-employed midlife and older adults in the United States (N = 1179), we examined five biomarkers linked to cardiovascular risk, including high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, triglyceride, interleukin-6, and C-reactive protein. Negative work-to-family spillover, measured using a four-item self-reported questionnaire, was included into our model to study its association with these cardiovascular risk biomarkers.

RESULTS

Our findings indicate a significant association between negative work-to-family spillover and cardiovascular risk biomarkers - higher triglycerides (β = 0.108, p < .001), interleukin-6 (β = 0.065, p = .026), and C-reactive protein (β = 0.067, p = .022), and lower HDL cholesterol (β = -0.104, p < .001). The associations on triglycerides (β = 0.094, p = .001) and HDL cholesterol (β = -0.098, p < .001) remained significant even after controlling numerous control variables of demographics, medication, health-status, and health-related behaviors. The findings were also consistent against slight variations in the analytic method and adjustment for multiple comparisons.

CONCLUSIONS

The current study supports the premise that spillover of work-related tensions into family life is associated with objective physiological changes that contribute to cardiovascular risk.

Sex Differences in the Relationship Between Emotional Support and Self-rated Health among Chinese Elderly

PURPOSE

This study aimed to explore sex differences in the association between emotional support and self-rated health among the elderly.

DESIGN

This was a cross-sectional survey based on the sub-project of China's National Basic Public Health Service Project-Health Management Services for the Elderly.

SETTING

Participants were recruited from ten rural townships in Jingyuan County, Gansu Province, Northwestern China.

SUBJECTS

1405 subjects aged 60 or above.

METHODS

Emotional support (consisting of 5 items) and self-rated health (evaluated by EQ-VAS) were investigated in this study. Multiple linear regression was conducted to consider the potential relationship.

RESULTS

The frequency of children visit and the number of providers of emotional support were positively associated with self-rated health among older women (β = 1.13, 95%CI = 0.25-2.02; β = 1.80, 95%CI = 1.01-2.58), whereas the number of close friends had a positive association with self-rated health among older men (β = 1.11, 95%CI = 0.20-2.01). The number of close relatives and the frequency of seeking emotional support were not found to be associated with self-rated health among both older men and older women.

CONCLUSION

The study has found that the relationship between emotional support and self-rated health was differed by sex, calling attention to the need for sex-specific interventions.

The relationship between depressive mood and subjective health in centenarians and near-centenarians: a cross-sectional study from Korean centenarian cohort

BACKGROUND

With the rapid increase in population longevity, more clinical attention is being paid to the overall health of long-lived people, especially centenarians. Subjective health, which is the perception of one's health status, predicts both mortality and declining physical function in older adults. The purpose of this study was to investigate the factors related to subjective health among centenarians and near-centenarians (ages ≥95) living in a rural area of South Korea.

METHODS

A total of 101 participants were enrolled from four different regions (Gurye, Gokseong, Sunchang, and Damyang), known as the Longevity Belt in Korea. Variables assessing physical and mental health, including the results of blood tests, were examined. Factors associated with good subjective health were identified with logistic regression analysis.

RESULTS

Fifty-six participants (59.6%) were subjectively healthy among the centenarians and near-centenarians. Logistic regression analysis revealed that depressive mood was the only factor associated with subjective health and was negatively correlated. The regression model explained 39% of the variance in subjective health.

CONCLUSIONS

These findings emphasize the importance of mental health at very advanced ages. Because depressive mood negatively correlates with subjective health, more attention is needed to prevent and manage mood symptoms of people of advanced ages, including centenarians.

Bidirectional Links of Daily Sleep Quality and Duration With Pain and Self-rated Health in Older Adults' Daily Lives

BACKGROUND

Sleep and health perceptions, such as self-ratings of pain and health are closely linked. However, the temporal ordering of such associations is not well understood, and it remains unclear whether sleep quality and sleep duration show similar or differential associations with health perceptions.

METHODS

We used ecological momentary assessment data from 123 young-old (66-69 years, 47% women) and 47 old-old adults (84-90 years, 60% women). Across 7 consecutive days, participants reported their sleep quality and sleep duration each morning and rated their momentary pain and health 6 times per day. We applied dynamic structural equation models to examine bidirectional links of morning reports of sleep quality and duration with daily levels of self-rated pain and health.

RESULTS

In line with the hypotheses, results showed that when participants reported better sleep quality than what is typical for them, they reported less pain and better self-rated health on the day that followed. Longer sleep duration was not linked with subsequent pain or self-rated health. On days when people rated their health as better than usual, they reported better sleep quality but not longer sleep duration the following night. These associations were not moderated by age, gender, or chronic pain.

CONCLUSION

Findings suggest that in old age, sleep quality is more relevant for health perceptions than sleep duration. Associations between sleep quality and self-rated health seem to be bidirectional; daily pain was linked to prior but not subsequent sleep quality.

Associations Between Childhood Victimization, Adult Victimization, and Physical Health Among Sexually Diverse Adults at Different Stages of Life

Purpose: Research examining health disparities in sexually diverse populations is quite variable. The purpose of the present article was to shed light on the conflicting findings pertaining to minority stress and health by examining the potential impact of age, childhood victimization, and different measurements of health. Methods: The present research used data from the Generations Study, a questionnaire study of sexually diverse adults (ages 18-60) surveyed between 2016 and 2019. We modeled direct and indirect links among (1) childhood exposure to physical or sexual abuse, (2) adult exposure to victimization or harassment, and (3) adult physical health status, assessed both subjectively and objectively. Participants were 1398 sexually diverse adults (e.g., lesbian, gay, bisexual); the present work only utilizes wave one of the data collected in 2016. Results: We found that both childhood abuse and adult harassment/victimization predicted sexually diverse adults' health status, but these associations only manifested as diagnosable disease outcomes among adults over 50. Associations between childhood abuse and adult health were partly attributable to the fact that abuse-exposed children were disproportionately exposed to harassment and victimization as adults. Conclusion: Our research makes a novel contribution to our understanding of the health effects of stigma by pinpointing the multiple, cascading pathways through which adversity relates to health.

The temporal relationship between depressive symptoms and self-rated health across adulthood

Objective: Depressive symptoms have been found to relate to diminished self-rated health (SRH), which is a reliable index of general health. Despite such associations, there is limited research examining the bidirectional temporal relationship between these variables. The current study is the first to investigate the longitudinal relationship between depressive symptoms and SRH utilizing a cross-lagged panel analysis in a sample that spans adulthood (ages 18-93).Method: Data from the Virginia Cognitive Aging Project were used to examine the temporal relationship between depressive symptoms and SRH in a cross-lagged panel analysis using structural equation modeling.Results: A bidirectional temporal relationship, which was not moderated by age, was established between depressive symptoms and SRH.Conclusion: This article is the first to demonstrate that depressive symptoms and SRH influence each other reciprocally over time across adulthood, even after controlling for relevant variables. Considering the ubiquity and ramifications of depressive symptoms among American adults, these results highlight the importance of investigating mechanisms that could elucidate the link between the variables in question.

Psychological distress and health perception in patients with a previous myocardial infarction or stroke: a national cross-sectional study

BACKGROUND

While understanding the impact of mental health on health perception improves patient-centered care, this relationship is not well-established in patients with cardiovascular disease (CVD). We examined the relationship between psychological distress and health perception in patients with a previous myocardial infarction (MI) and/or stroke.

METHODS

We extracted data for patients with a previous MI and/or stroke from the 2019 National Health Interview Survey (NHIS). Health perception was self-reported. Presence and severity of anxiety and depression were estimated using the Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-8 (PHQ-8). Binary analyses of anxiety/depression, multivariable logistic regressions controlling for confounders, and univariable analyses of confounders and anxiety/depression severity were performed.

RESULTS

Of 31,948 individuals for whom data on MI/stroke was available, 1235 reported a previous MI and 1203 a previous stroke. The odds of positive perceived health status were lower for individuals with anxiety/depression compared to those without anxiety/depression in both post-MI (anxiety OR 0.52, 95% CI = 0.32-0.85, P < 0.001; depression OR 0.45, 95% CI = 0.29-0.7, P < 0.001) and post-stroke groups (anxiety OR 0.61, 95% CI = 0.39-0.97, P < 0.001; depression OR 0.37, 95% CI = 0.25-0.55, P < 0.001) upon multivariable analyses. Increasing severity of anxiety/depression was also associated with worse perception of health status upon univariable analysis.

CONCLUSION

Among patients with a previous acute CVD event, those with psychological distress have worse perception of their health status. Understanding the range of patient health perceptions can help physicians provide more patient-centered care and encourage patient behaviors that may improve both CVD and mental health outcomes.

Health-related quality of life is impaired in bleeding disorders of unknown cause: results from the Vienna Bleeding Biobank

Background

Bleeding disorder of unknown cause (BDUC) is a diagnosis of exclusion after extensive investigation of coagulation and platelet function and is commonly seen among patients with mild-to-moderate bleeding disorders. Despite increasing awareness among treating physicians, little is known about the health-related quality of life (HrQoL) in BDUC.

Objectives

To investigate HrQoL in patients with BDUC in comparison to the general population and patients diagnosed with other established bleeding disorders.

Methods

Patients with mild-to-moderate bleeding disorders from the Vienna Bleeding Biobank, a prospective cohort study, were contacted via mail and phone to complete the 36-Item Health Survey Questionnaire form.

Results

In total, 333/657 (50.7%) patients completed the 36-Item Health Survey Questionnaire. Patients with BDUC (n = 207, 62%) had significantly impaired HrQoL both in physical (47.8 vs 49.2) and mental health parameters (42.9 vs 51.0) compared to the general population (n = 2914, 56% females), which remained after adjustment for sex and age in multivariable linear regression. The impairment in HrQoL, compared to patients with von Willebrand disease, platelet function defects, or mild clotting factor deficiencies, did not prevail after adjustment for age and sex. In patients with BDUC, age and the presence of at least 1 comorbidity were associated with impaired physical health but not sex or bleeding severity. Of all analyzed bleeding symptoms, only joint bleeding was associated with impaired physical health and gastrointestinal bleeding with mental health in BDUC.

Conclusion

The impairments in HrQoL in patients with BDUC emphasize the burden of BDUC on mental and physical well-being, encouraging early recognition and better counseling of patients with BDUC.

The relationship between frailty and social participation: focus on subjective health

OBJECTIVE

Active participation of the older adults in the society is crucial; however, frailty prevents social participation. Meanwhile, many older adults participate daily in social activities, even with frailty. This study aims to examine whether older adults with frailty have lower social participation than those without frailty in Japan. We also investigated whether older adults with frailty and higher subjective health participate in society to the same extent as the general older population. This study included 1,082 Japanese individuals aged 65 years and older participating in the online survey. Participants answered questions on social participation, frailty, subjective health, and demographics.

RESULTS

Participants in the robust group had higher social participation rates than those in the frailty and pre-frailty groups. Meanwhile, frail older participants with higher subjective health had similar social participation as the robust participants. Many older adults acquire frailty despite their individual effort. Meanwhile, improving subjective health may be effective, even with frailty. The relationship between subjective health, frailty, and social participation is primitive and further studies are needed.

Walking activity increases physical abilities and subjective health in people with seven different types of disabilities

Introduction

People with disabilities have a great risk of physical inactivity, which causes several diseases, dependency, and long-term care. Walking helps to increase physical activity, which leads to better overall health and independence. However, less research attention has focused on walking for people with disabilities, and even fewer studies have been considered for different types of disabilities. The present study aimed to demonstrate how walking distance was associated with people with seven different types of disabilities- including visual, hearing, physical/mobility, intellectual, learning, autism, and emotional/behavioral disabilities-in terms of their physical abilities and subjective health.

Methods

A total of 378 participants (aged 13-65) were gathered from seven national organizations in Thailand. A survey questionnaire on aspects of physical abilities (i.e., walking distance or manually rolling wheelchair distance; body balance; weightlifting; exercise duration and frequency); and subjective health (i.e., health status and satisfaction) was completed online by all participants.

Results

The walking distance was partially positive and associated with exercise duration, weightlifting, exercise frequency, and health status (all p values < 0.001), as well as body balance and health satisfaction (p = 0.001 and 0.004, respectively), after controlling for age, sex, and types of disability. This demonstrated that increasing the amount of distance walked could well lead to a more positive body and mind.

Discussion

The present study suggests that the possibility of having a walk and/or encouraging people with disabilities to walk for greater distances can have a significant impact on both their physical and subjective health outcomes.

Social and moral psychology of COVID-19 across 69 countries

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

The relationship between pre-surgery self-rated health and changes in functional and mental health in older adults: insights from a prospective observational study

BACKGROUND

Elective surgeries are among the most common health stressors in later life and put a significant risk at functional and mental health, making them an important target of research into healthy aging and physical resilience. Large-scale longitudinal research mostly conducted in non-clinical samples provided support of the predictive value of self-rated health (SRH) for both functional and mental health. Thus, SRH may have the potential to predict favorable adaptation processes after significant health stressors, that is, physical resilience. So far, a study examining the interplay between SRH, functional and mental health and their relative importance for health changes in the context of health stressors was missing. The present study aimed at addressing this gap.

METHODS

We used prospective data of 1,580 inpatients (794 complete cases) aged 70 years or older of the PAWEL study, collected between October 2017 and May 2019 in Germany. Our analyses were based on SRH, functional health (Barthel Index) and self-reported mental health problems (PHQ-4) before and 12 months after major elective surgery. To examine changes and interrelationships in these health indicators, bivariate latent change score (BLCS) models were applied.

RESULTS

Our analyses provided evidence for improvements of SRH, functional and mental health from pre-to-post surgery. BLCS models based on complete cases and the total sample pointed to a complex interplay of SRH, functional health and mental health with bidirectional coupling effects. Better pre-surgery SRH was associated with improvements in functional and mental health, and better pre-surgery functional health and mental health were associated with improvements in SRH from pre-to-post surgery. Effects of pre-surgery SRH on changes in functional health were smaller than those of functional health on changes in SRH.

CONCLUSIONS

Meaningful changes of SRH, functional and mental health and their interplay could be depicted for the first time in a clinical setting. Our findings provide preliminary support for SRH as a physical resilience factor being associated with improvements in other health indicators after health stressors. Longitudinal studies with more timepoints are needed to fully understand the predictive value of SRH for multidimensional health.

Age Matters: The Moderating Effect of Age on Styles and Strategies of Coping with Stress and Self-Esteem in Patients with Neoplastic Prostate Hyperplasia

The aim of this study was to analyze coping mechanisms and their psychological aspects during the treatment of neoplastic prostate hyperplasia. We have analyzed strategies and styles of coping with stress and self-esteem of patients diagnosed with neoplastic prostate hyperplasia. A total of 126 patients were included in the study. Standardized psychological questionnaires were used to determine the type of coping strategy by using the Stress Coping Inventory MINI-COPE, while a coping style questionnaire was used to assess the type of coping style by using the Convergence Insufficiency Symptom Survey (CISS). The SES Self-Assessment Scale was used to measure the level of self-esteem. Patients using adaptive strategies of coping with stress in the form of active coping, seeking support and planning had higher self-esteem. However, the use of maladaptive coping strategies in the form of self-blame was found to cause a significant decrease in patients' self-esteem. The study has also shown the choice of a task-based coping style to positively influence one's self-esteem. An analysis related to patients' age and coping methods revealed younger patients, up to 65 years of age, using adaptive strategies of coping with stress to have a higher level of self-esteem than older patients using similar strategies. The results of this study show that older patients, despite the use of adaptation strategies, have lower self-esteem. This group of patients should receive special care both from family and medical staff. The obtained results support the implementation of holistic care for patients, using psychological interventions to improve patients' quality of life. Early psychological consultation and mobilization of patients' personal resources may allow patients to change stress coping methods towards more adaptive forms.

Health trajectories across the work exit transition in the 1990s, 2000s, and 2010s: the role of working conditions and policy

PURPOSE

We examined health trajectories of Dutch older workers across their exit from the workforce in the 1990s, 2000s, and 2010s, testing the hypothesis that pre-post-exit health trajectories of workers with favourable and unfavourable working conditions increasingly diverged over time due to policy measures to extend working life.

METHODS

The Longitudinal Aging Study Amsterdam includes baseline samples in 1992/1993, 2002/2003 and 2012/2013 with two 3-year follow-up waves each. Selected respondents were aged 55 years and over who exited from a paid job within the first or second 3-year interval, up to and including the statutory retirement age (N = 522). Pre-post-exit trajectories were modelled using Generalized Estimating Equations with outcomes self-rated health and physical limitations and determinants physical demands, psychosocial demands, and psychosocial resources.

RESULTS

Average work exit age rose from 60.7 in the 1990s to 62.9 in the 2010s. On average, self-rated health decreased somewhat over successive periods and did not show pre-post-exit change; average physical limitations increased substantially both over successive periods and from pre- to post-exit. No support is found for our hypothesis. However, regardless of work exposures, we found sharp pre-post-exit increases in physical limitations in the 2010s.

CONCLUSION

Although these findings provide no support for our hypothesis of diverging health trajectories over time based on work exposure, they show that exiting at a higher age is linked to poorer pre- and post-exit health and to pre-post-exit increases in physical limitations, suggesting greater health care costs in the near future.

Changes in Tangible Social Support Over Time Among Older Adults Receiving Long-Term Services and Supports

The purpose of this study was to examine changes in and predictors of perceived tangible social support over a 2-year period among older adults new to LTSS. Linear mixed effects models were used to model repeated measures of tangible social support as a function of LTSS type [NH, AL, HCBS], personal, clinical, and health-related quality of life variables. AL residents reported greater initial tangible social support, but NH and HCBS residents improved more over time. Predictors of increased tangible social support over time included greater positive affect, sense of aesthetics, education, satisfaction with family relationships, and total number of close friends and family. Decreased tangible support over time was associated with greater depressive symptoms. Findings indicate the positive influence of NH and HCBS services on perception of tangible social support, and the importance of addressing depressive symptoms and assisting with the maintenance of important relationships.

How do individual, social, environmental, and resilience factors shape self-reported health among community-dwelling older adults: a qualitative case study

BACKGROUND

While older adults are living longer, they often face health challenges, including living with multiple chronic conditions. How older adults respond and adapt to the challenges of multimorbidity to maintain health and wellness is of increasing research interest. Self-reported health, emerging as an important measure of health status, has broad clinical and research applications, and has been described as a predictor of future morbidity and mortality. However, there is limited understanding of how individual, social, and environmental factors, including those related to multimorbidity resilience, influence self-reported health among community-dwelling older adults (≥ 65 years).

METHODS

Informed by the Lifecourse Model of Multimorbidity Resilience, this explanatory case study research explored older adults' perceptions of how these factors influence self-reported health. Data were generated through semi-structured telephone interviews with community-dwelling older adults.

RESULTS

Fifteen older adults participated in this study. Four key themes, specific to how these older adults describe individual, social, environmental, and multimorbidity resilience factors as shaping their self-reported health, were identified: 1) health is a responsibility - "What I have to do"; 2) health is doing what you want to do despite health-related limitations - "I do what I want to do"; 3) the application and activation of personal strengths - "The way you think", and; 4) through comparison and learning from others - "Looking around at other people". These themes, while distinct, were found to be highly interconnected with recurring concepts such as independence, control, and psychological health and well-being, demonstrating the nuance and complexity of self-reported health.

CONCLUSIONS

Findings from this study advance understanding of the factors that influence assessments of health among community-dwelling older adults. Self-reported health remains a highly predictive measure of future morbidity and mortality in this population, however, there is a need for future research to contribute additional understanding in order to shape policy and practice.

Relationship between the Engel Coefficient, Life Satisfaction, and Subjective Health for Senior Citizens in Korea: Moderating Effect of COVID-19

The purpose of this study was to explore the determinants of life satisfaction for Korean senior citizens. Subjective health and the Engel coefficient were used as the explanatory variables. This research also aimed to examine the moderating effect of Coronavirus disease 2019 (COVID-19) on the relationship between the Engel coefficient and life satisfaction for Korean senior citizens. Archival data (Korean longitudinal study of aging) were used for this work. The study period is 2018 and 2020; the number of observations was 3879. Multiple linear regression analysis was performed to test the research hypotheses. To examine further, this research performed additional analyses: sub-sample analysis, median split, and independence tests. The results indicated that the Engel coefficient is negatively associated with life satisfaction, while subjective health is positively related to life satisfaction. Moreover, Korean senior citizens' life satisfaction was higher during the COVID-19 pandemic. This research provides information for building policy for senior Korean citizens.

Subjective health perception prioritizes psychological well-being over physical function in advanced ALS: A multigroup structural equation modeling analysis

BACKGROUND

Despite declining physical function, individuals with ALS report relative preservation of overall health perception, or health-related quality of life (HRQoL). This paradoxical finding is attributed to psychological adaptation to deficits.

OBJECTIVE

The aim of this cross-sectional study was to examine reprioritization of factors that determine HRQoL with disease progression.

METHODS

As standard care, patients with ALS self-reported ALSFRS-R (measure of bulbar, motor, and respiratory function), PHQ-9 (measure of depression), and EQ-5D-3L (utility index that includes a visual analog scale asking about health perception [EQ-VAS]). ALS was staged by the FT9 method and classified into early (stages 0-2) and late (stages 3-4) disease. Multigroup structural equation modeling was used to evaluate weights of physical (PHY) and psychological well-being (PSY) for early and late disease, on EQ-VAS (as a measure of overall HRQoL).

RESULTS

There were 578 patients (mean age 61.5 ± 11.9, 59% male) with ALS: 423 (73%) early and 155 (27%) late disease. A measurement model was established with good model fit (RMSEA = 0.076, CFI = 0.943, SRMR = 0.045). In adjusted models, standardized weights of PHY and PSY on HRQoL in early disease were 0.34 (standard error = 0.06) and 0.24 (0.06) respectively, whereas for late disease they were 0.39 (0.07) and 0.42 (0.07). Importantly, PHY and PSY were significantly correlated in early but not in late disease.

CONCLUSIONS

Our study found health perception is more representative of psychological well-being and less representative of physical function across the disease progression. Greater allocation for psychological health would be the most effective strategy to maximize subjective health status as ALS advances.

Authentic leader(ship) development and leaders' psychological well-being: an outcome-wide analysis

Purpose

Despite a fast-growing interest in leadership development programs, there is limited research on the impacts of leadership development and a narrow focus on professional competencies as outcomes. The authors’ aim was to test whether authentic leadership development (ALD), an identity-based leadership development approach, is associated with positive changes in leaders' psychological well-being.

Design/methodology/approach

In a large sample of leaders (N = 532) from five different ALD programs, the authors conducted a pre-registered outcome-wide analysis and tested within-person changes in key indicators of psychological well-being and explored individual differences moderating these changes.

Findings

Results showed significant increases in self-concept clarity, sense of purpose in life and personal growth about two to three weeks after the programs ended. Changes in stress and health were not consistent. These changes did not differ across socio-demographic status (gender, age), work-related factors (leadership, industry and tenure) and most personality factors (extraversion, agreeableness, openness to experience). Those with high emotional variability experienced greater improvements in some outcomes of well-being while individuals with higher income and conscientiousness (who had high baseline self-concept clarity) experienced smaller improvements. Longer follow-up assessments were associated with smaller changes.

Originality/value

As one of the most comprehensive assessments of ALD outcomes to date, this study shows the potential of ALD for improving outcomes beyond leadership skills, the well-being of leaders, highlighting the return on value in leadership development and pointing to learning and development as a workplace well-being intervention.

Factors associated with subjective state of health in college students

Although the COVID-19 pandemic has been deeply painful, it has provided a rare opportunity to study the behavioral responses of individuals in adapting to an unprecedented life event. An analysis of participants' subjective health ratings during the COVID-19 pandemic was conducted by utilizing data from a survey of college students across seven universities in the US. In this study, we challenged the unidimensional factors to the subjective wellbeing by considering all multiplicative associations of those factors. Considering the interaction terms is especially important as not considering those impacts might obscure our understanding regarding the real associations. It was found that while higher screen hours, BMI, and various negative feelings are negatively associated with higher subjective health, higher family income, social class, and students' and their mothers' educations are associated with a higher subjective well-being. However, the impacts of the majority variables are interactive. For instance, the impact of mother's education varies based on the genders of students, or the impact of screen hours differs based on family income. In addition, the degree students limit of exercise at home or gym changes based on the negative feeling they experience during the pandemic. Remarkably, during the pandemic while irrationally limiting exercise at home was associated with a lower subjective health, limiting exercise at gym was positively associated with the response.

Pathways to healthy aging - Exploring the determinants of self-rated health in older adults

OBJECTIVE

The decade 2021-2030 has been declared the Decade of Healthy Aging by the United Nations General Assembly, underlining that health is central to the experience of older age and the opportunities that aging brings. Self-rated health (SRH) appears consistent with the state of objective health, and therefore can serve as a simple core indicator of healthy aging. SRH can be affected by psychological and lifestyle factors, and by the developmental and sociodemographic context, which can directly and indirectly influence subjective health status. The aim of the present study was to establish the structure of the relationships between SRH, health-related behavior, subjective wellbeing, developmental tasks attainment and sociodemographic factors in the late-life period.

METHODS

The study group consisted of 340 Polish retired seniors, aged 61 to 94 (M = 70.75, SD = 6.48): 88 men (25.9 %) and 252 women (74.1 %). The respondents completed the following measures: 10-point numerical scale for SRH, Health-Related Questionnaire for Seniors, Satisfaction with Life Scale, Developmental Tasks Questionnaire for Seniors and a sociodemographic survey.

RESULTS

The group demonstrated a medium level of SRH and other variables. SHR was positively correlated with health-related behavior, wellbeing, developmental tasks attainment and perceived economic status, and negatively with age. Structural equation model revealed that health-related behavior, wellbeing, age and economic status have a direct influence on SRH. Developmental tasks attainment was found to predict health behavior, although no direct relationship with SRH was found.

CONCLUSIONS

A broader understanding of healthy aging is achieved by considering the context of its factors. Psychological interventions should promote a healthy lifestyle and adapt it to the late life period to promote health among seniors.

Self-reported health and the well-being paradox among community-dwelling older adults: a cross-sectional study using baseline data from the Canadian Longitudinal Study on Aging (CLSA)

Background

Self-reported health is a widely used epidemiologic measure, however, the factors that predict self-reported health among community-dwelling older adults (≥65 years), especially those with multimorbidity (≥2 chronic conditions), are poorly understood. Further, it is not known why some older adults self-report their health positively despite the presence of high levels of multimorbidity, a phenomenon known as the well-being paradox. The objectives of this study were to: 1) examine the factors that moderate or mediate the relationship between multimorbidity and self-reported health; 2) identify the factors that predict high self-reported health; and 3) determine whether these same factors predict high self-reported health among those with high levels of multimorbidity to better understand the well-being paradox.

Methods

A cross-sectional analysis of baseline data from the Canadian Longitudinal Study on Aging was completed (n = 21,503). Bivariate stratified analyses were used to explore whether each factor moderated or mediated the relationship between multimorbidity and self-reported health. Logistic regression was used to determine the factors that predict high self-reported health in the general population of community-dwelling older adults and those displaying the well-being paradox.

Results

None of the factors explored in this study moderated or mediated the relationship between multimorbidity and self-reported health, yet all were independently associated with self-reported health. The ‘top five’ factors predicting high self-reported health in the general older adult population were: lower level of multimorbidity (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.74-0.76), female sex (OR 0.62, CI 0.57-0.68), higher Life Space Index score (OR 1.01, CI 1.01-1.01), higher functional resilience (OR 1.16, CI 1.14-1.19), and higher psychological resilience (OR 1.26, CI 1.23-1.29). These same ‘top five’ factors predicted high self-reported health among the subset of this population with the well-being paradox.

Conclusions

The factors that predict high self-reported health in the general population of older adults are the same for the subset of this population with the well-being paradox. A number of these factors are potentially modifiable and can be the target of future interventions to improve the self-reported health of this population.

Awareness of age-related change, chronological age, subjective age and proactivity: An empirical study in China

An aging workforce and the increasing value placed on employees' proactivity are two important features of current workplaces. We address the extent to which this proactivity is affected by age and aging. The study has two objectives. First, it aims to validate the concept of awareness of age-related change (AARC) in the Chinese context. Second, it compares the explanatory power of AARC with that of chronological age and subjective age in predicting three types of proactivity: task proactivity, development proactivity and organization proactivity. We used the ten-item AARC instrument in a survey of teachers (n = 421, mean age = 41.0) in China, and validated its content by comparing the responses of a subsample of these teachers (n = 33, mean age = 42.5) to questions asked in a semi-structured interview. This confirmed the validity of the instrument's content, and its applicability beyond North America and Europe, in a Chinese context. We then show that awareness of positive and negative age-related changes (AARC-Gains and AARC-Losses) are, respectively, positively and negatively associated with the three types of proactivity, and that they are better predictors than chronological age and subjective age. The research adds weight to challenges to negative age stereotyping--that older employees are set in their ways and less proactive--and to claims about the value of AARC for measuring aging, by showing that this factor can predict outcomes beyond health and the concerns of older adults.

The effects of health shocks on family status: do financial incentives encourage marriage?

This paper asks whether marriage decisions of unmarried mature couples are driven by the prospect of financial advantages for the later widowed after one partner has suffered a serious health shock. We hypothesize that, in contrast to traditional marriage models, such health shocks may induce unmarried couples to obtain economic benefits, such as survivors' pensions in particular, through marriage in advance of one partner's death. This question has not yet been studied empirically. Hazard models capturing unobserved effects are applied to longitudinal data of the German Socioeconomic Panel. It turns out that the probability of marriage after male partners' health shocks can increase significantly depending on the amount of expected survivors' pensions for the (likely) surviving female partners. In contrast, an increased probability of marriage after health shocks to women (depending on the expected financial benefits to men) was not found. These findings are supported by various robustness checks. Economic and political implications are discussed and the results are placed in an international context.

Behavioral and Mental Responses towards the COVID-19 Pandemic among Chinese Older Adults: A Cross-Sectional Study

The novel COVID-19 pandemic spread quickly and continuously influenced global societies. As a vulnerable population that accounted for the highest percentage of deaths from the pandemic, older adults have experienced huge life-altering challenges and increased risks of mental problems during the pandemic. Empirical evidence is needed to develop effective strategies to promote preventive measures and mitigate the adverse psychological impacts of the COVID-19 pandemic. This study aimed to investigate the behavioral responses (i.e., preventive behaviors, physical activity, fruit and vegetable consumption) and mental responses (i.e., depression and loneliness) towards the COVID-19 pandemic among Chinese older adults. A further aim was to identify the associations among demographics, behavioral responses, and mental responses. Using a convenience sampling approach, 516 older adults were randomly recruited from five cities of Hubei province in China. Results of the cross-sectional survey showed that 11.7% of participants did not adhere to the WHO recommended preventive measures, while 37.6% and 8.3% of participants decreased physical activity and fruit–vegetable consumption respectively. For mental responses, 30.8% and 69.2% of participants indicated significantly depressive symptoms and severe loneliness, respectively. Participants’ behavioral and mental responses differed significantly in several demographics, such as age group, living situation, marital status, education levels, household income, medical conditions, and perceived health status. Demographic correlates and behavioral responses could significantly predicate the mental response with small-to-moderate effect sizes. This is the first study to investigate the characteristics of behavioral and mental responses of Chinese older adults during the COVID-19 pandemic. Research findings may give new insights into future developments of effective interventions and policies to promote health among older adults in the fight against the pandemic.

Association between physical limitations and depressive symptoms among Indian elderly: marital status as a moderator

BACKGROUND

Depression among the elderly is well-documented and associated with socio-economic factors, physical and mental health conditions. Few studies have focused on older adults' physical limitations and depressive symptoms. However, very little is known about marital status' role in such associations, especially in India. The present study examines the association between physical limitations and self-reported depressive symptoms and moderating role of marital status in such association separately for men and women.

METHODS

The present study used data from the Longitudinal Ageing Study in India (LASI) wave 1, 2017-2018, a nationally and state representative longitudinal large-scale survey of ageing and health. For the present research, a total sample of 20,806 older adults aged 60+ years was selected after excluding missing values. Along with descriptive statistics, binary logistic regression analysis and interaction effect of marital status were applied to examine the association between physical limitations (functional limitations and mobility difficulty) with the depressive symptoms separately for men and women.

RESULTS

About 58, 50, and 45% elderly reported having depressive symptoms and had difficulty in 2+ ADLs, 2+ IADLs, and 2+ mobility difficulties, respectively. By the marital status, the prevalence of depressive symptoms was higher among currently unmarried than currently married, irrespective of type and number of physical limitations. The unadjusted, marital and multivariate-adjusted association suggested that elderly with more than two ADLs, IADLs, and mobility difficulty had higher odds of depressive symptoms. The gender stratified interaction effect of marital status and physical limitations on depressive symptoms indicated that currently unmarried elderly, particularly unmarried older women with 2+ ADLs (OR = 2.85; CI 95% = 1.88-3.09), 2+ IADLs (OR = 2.01; CI 95% = 1.74-2.31) and 2+ mobility difficulty (OR = 2.20; CI 95% = 1.86-2.60) had higher odds of depressive symptoms. However, such association was only valid for unmarried men having mobility difficulty.

CONCLUSION

The study highlights that the elderly with physical limitations such as ADLs, IADLs, and mobility difficulty require attention and care. Although married elderly are less likely to have depressive symptoms even with all the mentioned physical limitations, unmarried women are more vulnerable to have depressive symptoms with physical limitations.

Using Machine Learning to Predict Frailty from Cognitive Assessments

This paper explores the relation between cognitive and physical aspects of the human body from a machine learning standpoint. We propose to use performance on cognitive assessments to predict frailty of elderly adults with different regression and classification models. We propose a preprocessing scheme with oversampling and imputation to overcome the challenge of an imbalanced data distribution on the existing dataset. We validate the capability of classification models to predict frailty on patients given cognitive input data and provide evidence that machine learning models depend on clinically-defined thresholds.

Self-rated health and incident dementia over two decades: Replication across two cohorts

This prospective study examined the association between self-rated health and incident dementia in two large cohorts of middle-aged and older adults. Participants were drawn from the Health and Retirement Study (HRS, N = 13,839, Mean Age = 64.32, SD = 9.04) and the English Longitudinal Study of Ageing (ELSA, N = 4649, Mean Age = 64.44, SD = 9.97). Self-rated health and covariates were assessed at baseline in 1998 and 2002, and cognitive status was tracked for up to 21 years in HRS and 17 years in ELSA, respectively. Controlling for demographic factors, poorer self-rated health was associated with higher risk of incident dementia in HRS (HR: 1.18, 95%CI: 1.12-1.24, p < .001) and ELSA (HR: 1.38, 95%CI: 1.23-1.55, p < .001). These associations remained significant when diabetes, hypertension, smoking, physical inactivity, depressive symptoms, personality, and polygenic risk for Alzheimer's Disease were included as additional covariates or when cases occurring within the first ten years of follow-up were excluded from the analyses. There was no replicable evidence that age, sex, education, race or ethnicity moderated the association. Self-rated health is a long-term, replicable predictor of incident dementia that is independent of genetic, clinical, and behavioral risk factors.

Are there gender differences in the trajectories of self-rated health among chinese older adults? an analysis of the Chinese Longitudinal Healthy Longevity Survey (CLHLS)

BACKGROUND

Self-rated health (SRH) is a good predictor of morbidity and mortality. Extensive research has shown that females generally report poorer SRH than males but still tend to live longer. Previous studies used cross-sectional or pooled data for their analyses while ignoring the dynamic changes in males' and females' SRH statuses over time. Furthermore, longitudinal studies, especially those that focus on older adults, typically suffer from the incompleteness of data. As such, the effect of dropout data on the trajectories of SRH is still unknown. Our objective is to examine whether there are any gender differences in the trajectories of SRH statuses in Chinese older adults.

METHODS

The trajectories of SRH were estimated using the pattern-mixture model (PMM), a special latent growth model, under non-ignorable dropout data assumption. We analyzed the Chinese Longitudinal Healthy Longevity Survey (CLHLS) data of 15,613 older adults aged 65 years and above, collected from 2005 to 2014.

RESULTS

The results demonstrated the effect of non-ignorable dropout data assumptions in this study. The previous SRH score was negatively associated with the likelihood of dropping out of the study at the next follow-up survey. Our results showed that both males and females in China perceive their SRH as decreasing over time. A significant gender difference was found in the average SRH score (female SRH was lower than male SRH) in this study. Nonetheless, based on the results obtained using the PMM, there are no gender differences in the trajectories of SRH at baseline as well as in the rate of decline among the total sample. The results also show that males and females respond to SRH predictors similarly, except that current drinking has a more pronounced positive effect on males and healthcare accessibility has a more pronounced positive effect on females.

CONCLUSIONS

Our results suggest that missing data have an impact on the trajectory of SRH among Chinese older adults. Under the non-ignorable dropout data assumptions, no gender differences were found in trajectories of SRH among Chinese older adults. Males and females respond to SRH predictors similarly, except for current drinking habit and healthcare accessibility.

Older immigrants perceived health after migration to the United States: Influence of age and level of acculturation

OBJECTIVES

To determine the age-related differences in the association between level of acculturation and perceptions about change in health status after migration in mid- to late-life immigrants.

DESIGN

Cross-sectional study.

SETTING

Nationally representative cohort of legal U.S. immigrants.

PARTICIPANTS

Legal immigrants ≥50 years of age.

MEASUREMENTS

The outcome was perceived change in health status, determined by the survey question, "compared with your health right before you most recently came to the United States to live, would you say that your health is better now, about the same or worse?" The main predictor included age group (50-64, 65-74, and ≥75 years) and secondary variable of interest was level of acculturation. Analyses were adjusted for demographic characteristics, medical, and functional comorbidities.

RESULTS

Immigrants age ≥75 years were more likely to report worse health after migration [RRR 1.93, 95% CI (1.17, 3.17), p < 0.01] compared with immigrants of 50-64 years, but this difference was not statistically significant in the adjusted model. Acculturation level was associated with increased likelihood of reporting worse health status, [RRR 2.10, (1.02, 4.35), p < 0.05] for somewhat acculturated and [RRR 2.55, (1.10, 5.88), p < 0.05] for most acculturated, compared with participants who were not acculturated.

CONCLUSION

The oldest immigrant group (≥75 years) was more likely to report worse health after migration, but this association was no longer significant after accounting for acculturation level and other covariates. Future work should be undertaken to identify specific health needs across older immigrant age groups and identify acculturative stressors that negatively impact health.

Age- and time-varying associations between subjective health and episodic memory in older adults

OBJECTIVE

There are positive correlations between subjective health reports and episodic memory performance in older adults. However, previous studies have not evaluated the scope of such complex relationships, nor the potentially nonlinear magnitude of these correlations across age and time. We employed multiple subjective heath indices to evaluate the scope and nonlinearity of such relationships with memory performance.

METHOD

We utilized a cross-sectional (N = 2,783 at baseline) and longitudinal sample (N = 311) of healthy older adults aged 65 and older from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study. We used time-varying effects modeling (TVEM) to assess potential differences in relationship magnitudes between memory and three subjective health subscales (general health, role physical function, and physical function, from the Short Form Health Survey; SF-36) across five years.

RESULTS

Episodic memory positively predicted all subjective health measures cross-sectionally and longitudinally in our sample. TVEM revealed the relationships between all subjective health measures and episodic memory were stable across age. While role physical function and physical function maintained stable relationships with episodic memory across time, general health became increasingly coupled with memory five years following baseline.

DISCUSSION

Together, our findings highlight stable and varying relationships between episodic memory and multiple subjective health indicators across metrics of time in older adults.

Development of a Nomogram for Predicting Depression in the Elderly Using Patient Health Questionnaire-9 among a Nationwide Sample of Korean Elderly

This cross-sectional study developed a nomogram that could allow medical professionals in the primary care setting to easily and visually confirm high-risk groups of depression. This study analyzed 4011 elderly people (≥60 years old) who completed a health survey, blood pressure, physical measurement, blood test, and a standardized depression screening test. A major depressive disorder was measured using the Korean version of the Patient Health Questionnaire (PHQ-9). This study built a model for predicting major depressive disorders using logistic regression analysis to understand the relationship of each variable with major depressive disorders. In the result, the prevalence of depression measured by PHQ-9 was 6.8%. The results of multiple logistic regression analysis revealed that the major depressive disorder of the elderly living alone was significantly (p < 0.05) related to monthly mean household income, the mean frequency of having breakfast per week for the past year, moderate-intensity physical activity, subjective level of stress awareness, and subjective health status. The results of this study implied that it would be necessary to continuously monitor these complex risk factors such as household income, skipping breakfast, moderate-intensity physical activity, subjective stress, and subjective health status to prevent depression among older adults living in the community.

Pessimistic health and optimistic wealth distributions perceptions in Germany and the UK: evidence from an online-survey

Background

Inequalities in health and wealth distributions are becoming pressing societal problems in many countries. How these inequalities are perceived and to what degree perceptions are aligned with actual distributions, is important for trust in public health services, social and economic policies, and policymakers. This study aims to assess perceived and desired levels of inequality in health and wealth in Germany and the UK.

Methods

The online-survey was filled out by 769 volunteers (322 from Germany, 447 from the UK), recruited from an existing commercial panel (Prolific Academic) or via Facebook advertisements in 2019. Perceived and ideal national health and wealth distributions were assessed and compared to actual health indicators (i.e. days absent from work, number of visits to general practitioners (GPs) and self-rated health), and actual wealth distributions with t-tests.

Results

A pronounced gap emerged between the estimated, ideal and actual inequality. Both samples strikingly underestimated the proportion of (very) good health in the national distribution by a factor of ~ 2.3 (participants estimated that 34% of the German and 36% of the UK population respectively are very healthy or healthy, while the actual proportion in the population was 75% in Germany and 84% in the UK, P < 0.001 for all). Moreover, actual health distributions were much closer to the desired than the perceived health distributions (78% of German and 72% of UK participants ideally being very healthy or healthy). A reversed pattern of results emerged for wealth in both samples, with wealth inequality being strikingly worse than desired and inequality being underestimated by a factor ~ 1.7 (P < 0.001 for all). Results were consistent across demographic groups.

Conclusions

Respondents in both Germany and the UK have profoundly negative misperceptions regarding the distribution of health, which contrasts with starkly positive misperceptions regarding the distribution of wealth, indicating that the public is healthier but poorer than they think. More importantly, from a public health perspective, a high level of consensus emerged, with both healthy and wealthy participants misperceiving health and wealth distributions.

Associations between self-rated health and depressive symptoms among older adults: Does age matter?

OBJECTIVE

It has been suggested that self-rated health (SRH), a construct of overall subjective health, is predicted by depressive symptoms. However, depressive symptoms were also found to predict SRH. The present study aimed to simultaneously examine these alternatives as well as test the potential moderating role of age.

METHODS

Data concerning self-reported measures from two consecutive waves of the Survey of Health, Aging and Retirement in Europe (SHARE) were examined by using a longitudinal cross-lagged panel analysis.

RESULTS

The model that included the effects of both paths, i.e. from SRH to depressive symptoms and from depressive symptoms to SRH, demonstrated better fit than models including one or no cross-lagged paths. However, the longitudinal effect of SRH on depressive symptoms was stronger than the longitudinal effect of depressive symptoms on SRH, particularly among adults aged 65-79. The longitudinal effect of depressive symptoms on SRH was stronger among individuals aged 80 and older, compared with younger ages.

CONCLUSIONS

Bidirectional effects may exist between SRH and depressive symptoms among adults aged 50 and older. Special attention should be paid to the unique effects of SRH on depressive symptoms in the years following retirement and also to depressive symptoms on SRH among the old-old.

Family caregivers' distress responses to daily behavioral and psychological symptoms of dementia: The moderating role of relationship quality

OBJECTIVES

Behavioral and psychological symptoms of dementia (BPSD) are associated with distress among caregivers of persons with dementia (PWD), but less is known about how relationship quality may buffer this association. This study examines the association between daily BPSD and daily perceived distress among family caregivers and the moderating role of relationship quality.

METHODS

Data were from 173 family caregivers of PWD from the Daily Stress and Health study. Relationship quality was assessed at the baseline interview; then on each of the 8 following consecutive days, caregivers reported frequency of daily BPSD (six domains) and their respective distress (calculated as daily distress sum and daily distress mean scores) through daily evening phone interviews at home. A 2-level multilevel model approach was employed to differentiate within-person (WP) and between-person (BP) effects.

RESULTS

Greater daily BPSD occurrence was associated with higher daily distress (sum and mean scores) at WP and BP levels. However, relationship quality moderated the association between daily BPSD occurrence and daily distress sum scores at both WP and BP levels. Caregivers who reported better relationship quality with the PWD had lower levels of daily distress sum scores in response to daily BPSD occurrence, compared to their counterparts with poorer relationship quality.

CONCLUSIONS

This study revealed that relationship quality attenuated the effect of daily BPSD occurrence on caregivers' distress. Future dementia caregiver education and support programs should consider building relationship quality into the personalized program design to improve caregiver mental health and well-being.

The bidirectional relationship between sense of purpose in life and physical activity: a longitudinal study

People with a greater sense of purpose in life may be more likely to engage in physical activity. At the same time, physical activity can contribute to a sense of purpose in life. The present research tests these hypotheses using a cross-lagged panel model in a nationally representative, longitudinal panel of American adults (N = 14,159, M_age = 68). An increase in sense of purpose in life was associated with higher physical activity four years later, above and beyond past activity levels. Physical activity was positively associated with future levels of sense of purpose in life, controlling for prior levels of purpose in life. Results held in a second national panel from the US with a nine-year follow-up (N = 4,041, M_age = 56). The findings demonstrate a bidirectional relationship between sense of purpose in life and physical activity in large samples of middle-aged and older adults tracked over time.

Health congruence paradox in older adults: Contribution of cognition and relational visits

The health congruence paradox can have important implications for those working with older adults as older adults' health understanding may be vague or directed toward health concerns other than those medically identified. Objective health was measured as diagnosed conditions from medical records. Two measures of subjective health were obtained through relational visits of university students, 1) health concerns older adults reported on a visit survey, 2) health concerns students reported during casual conversation. The results showed that community dwelling older adults with lower cognitive functioning ability were more susceptible to the health congruence paradox on the subjective measure of the survey report. Qualitative analysis of health concerns from subjective measures found older adults most concerned about health conditions impacting daily functioning, such as mobility and cognition, but not diagnosed hypertension. This mixed methods study confirmed the importance of understanding older adults' subjective health with measures easily obtained through relational visits with university students.

Effects of healthcare access and financial status on self-rated health among adults living alone in South Korea

Assessments of the overall health status of people living alone are important for developing health promotion programs and delivering appropriate health services. In the context of universal social health insurance system of South Korea, the relationship between failure to access health-care and self-rated health among adults living alone has given little attention. In addition, the influence of objective financial status on self-rated health in adults living alone has not explored so far. The sample of the present study comprised 4,852 adults who participated in the cross-sectional 2015 Korea National Health and Nutrition Examination Survey. The main finding was that the unmet health-care needs resulting from the inability to access health-care services during the previous 12 months was independently associated with fair or poor self-rated health, especially for women living alone. Having an income below the subsistence level was significantly associated with fair or poor self-rated health among women living alone. The findings of this study demonstrate the need for policies enabling appropriate delivery of health-care services, especially for women living alone. It is necessary to provide community-based monitoring programs related to general health for women living alone with a household income below the minimum cost-of-living.

Stigma associated with parental depression or cancer: Impact on spouse and offspring's cortisol levels and socioemotional functioning

Stress associated with caring for a mentally ill spouse can adversely affect the health status of caregivers and their children. Adding to the stress of caregiving is the stigma often placed against spouses and children of people with mental illness. Contrary to mental illness, many physical disorders such as cancer may be less stigmatized (expect pulmonary cancer). In this study, we measured externalized and internalized stigma, as well as psychological (depressive symptoms and stressful life events) and physiological (basal salivary cortisol levels) markers of stress in 115 spouses and 154 children of parents suffering from major depressive disorder, cancer, or no illness (control group). The results show that spouses and children from families with parental depression present significantly more externalized stigma than spouses and children from families with parental cancer or no illness, although we find no group differences on internalized stigma. The analysis did not show a significant group difference either for spouses or their children on depressive symptomatology, although spouses from the parental depression group reported greater work/family stress. Finally, we found that although for both spouses children the awakening cortisol response was greater on weekdays than on weekend days, salivary cortisol levels did not differ between groups. Bayes factor calculated on the null result for cortisol levels was greater than 100, providing strong evidence for the null hypothesis H0. Altogether, these results suggest an impact of stigma toward mental health disorder on psychological markers of stress but no impact of stigma on physiological markers of stress. We suggest that these results may be due to the characteristics of the families who participated in the present study.

The Relationship between Life Course Socioeconomic Conditions and Objective and Subjective Memory in Older Age

While objective memory performance in older adults was primarily shown to be affected by education as indicator of life course socioeconomic conditions, other life course socioeconomic conditions seem to relate to subjective memory complaints. However, studies differ in which life course stages were investigated. Moreover, studies have explored these effects in an isolated way, but have not yet investigated their unique effect when considering several stages of the life course simultaneously. This study, therefore, examined the respective influence of socioeconomic conditions from childhood up to late-life on prospective memory (PM) performance as an objective indicator of everyday memory as well as on subjective memory complaints (SMC) in older age using structural equation modeling. Data came from two waves of the Vivre-Leben-Vivere aging study (n=993, Mage=80.56). The results indicate that only socioeconomic conditions in adulthood significantly predicted late-life PM performance. PM performance was also predicted by age and self-rated health. In contrast, SMC in older age were not predicted by socioeconomic conditions at any stage of the life course but were predicted by level of depression. In line with the cognitive reserve hypothesis, present results highlight the significance of education and occupation (adulthood socioeconomic conditions) for cognitive functioning in later life.

Developing a Predictive Model for Depressive Disorders Using Stacking Ensemble and Naive Bayesian Nomogram: Using Samples Representing South Korea

This study provided baseline data for preventing depression in female older adults living alone by understanding the degree of their depressive disorders and factors affecting these depressive disorders by analyzing epidemiological survey data representing South Koreans. To achieve the study objective, this study explored the main risk factors of depressive disorders using the stacking ensemble machine technique. Moreover, this study developed a nomogram that could help primary physicians easily interpret high-risk groups of depressive disorders in primary care settings based on the major predictors derived from machine learning. This study analyzed 582 female older adults (≥60 years old) living alone. The depressive disorder, a target variable, was measured using the Korean version of Patient Health Questionnaire-9. This study developed five single predictive models (GBM, Random Forest, Adaboost, SVM, XGBoost) and six stacking ensemble models (GBM + Bayesian regression, RandomForest + Bayesian regression, Adaboost + Bayesian regression, SVM + Bayesian regression, XGBoost + Bayesian regression, GBM + RandomForest + Adaboost + SVM + XGBoost + Bayesian regression) to predict depressive disorders. The naive Bayesian nomogram confirmed that stress perception, subjective health, n-6 fatty acid, n-3 fatty acid, mean hours of sitting per day, and mean daily sleep hours were six major variables related to the depressive disorders of female older adults living alone. Based on the results of this study, it is required to evaluate the multiple risk factors for depression including various measurable factors such as social support.

Diverging ideas of health? Comparing the basis of health ratings across gender, age, and country

BACKGROUND

Self-rated health (SRH) is arguably the most widely used generic health measurement in survey research. However, SRH remains a black box for researchers. In our paper, we want to gain a better understanding of SRH by identifying its determinants, quantifying the contribution of different health domains to explain SRH, and by exploring the moderating role of gender, age groups, and the country of residence.

METHOD

Using data from 61,365 participants of the fifth wave (2013) of the Survey of Health, Ageing and Retirement in Europe (SHARE) living in fifteen European countries, we explain SRH via linear regression models. The independent variables are grouped into five health domains: functioning, diseases, pain, mental health, and behavior. Via dominance analysis, we focus on their individual contribution to explaining SRH and compare these contributions across gender, three age groups, and fifteen European countries.

RESULTS

Our model explains SRH rather well (R² = .51 for females/.48 for males) with functioning contributing most to the appraisal (.20/.18). Diseases were the second most relevant health dimension (.14/.16) followed by pain (.08/.07) and mental health (.07/.06). Health behavior (.02/.01) was less relevant for health ratings. This ranking held true for almost all countries with only little variance overall. A comparison of age groups indicated that the contribution of diseases and behavior to SRH decreased over the life-course while the contribution of functioning to R² increased.

CONCLUSION

Our paper demonstrates that SRH is largely based on diverse health information with functioning and diseases being most important. However, there is still room for idiosyncrasies or even bias.

Importance of Personality for Objective and Subjective-Physical Health in Older Men and Women

Objective and subjective health generally have a positive relationship, although their association may be moderated by factors such as gender and personality. We aimed to analyze the association between personality and objective (metabolic syndrome (MetS)) and subjective-physical health in older men and women. For this purpose, in 138 participants (53.6% women, Mage = 66.85), neuroticism, conscientiousness, extraversion, openness, and agreeableness (NEO Five Factor Inventory), subjective-physical health (Short Form Health Survey, SF-36), and MetS (employing waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, and glycated hemoglobin) were assessed. Logistic regression analysis was performed to analyze whether personality was associated with MetS. Moreover, hierarchical regression analyses were conducted to analyze the relationship between personality or MetS, and subjective-physical health. Finally, gender and personality moderation analyses were performed with PROCESS. Results showed that higher neuroticism was associated with an increased likelihood of MetS, whereas higher neuroticism and lower extraversion were associated with lower subjective-physical health. Moreover, the negative relationship between MetS and subjective-physical health was stronger in individuals with low conscientiousness. Regarding gender differences, only in women, higher extraversion was related to a decreased likelihood of MetS, and MetS was related to lower subjective-physical health. In conclusion, higher neuroticism is the main vulnerability health factor, whereas to a lesser extent extraversion and conscientiousness are protective factors. Furthermore, the association between objective and subjective health is not direct, but it may vary depending on personality and gender.
