Health-related quality of life in community-dwelling older Whites and African Americans

Gender differences in the association between cardiovascular diseases and major depressive disorder among older adults in India

Background

Despite the global disease burden associated with the co-occurrence of cardiovascular diseases (CVDs) and depression, depression remains underdiagnosed and undertreated in the CVD population, especially among older adults in India. As such, this study examines (1) the association between single and multiple CVDs and major depressive disorder among older Indians; (2) whether this association is mediated by older adults' self-rated health and functional limitations; and (3) whether these associations vary for older men and women.

Methods

Data come from the 2017-18 wave 1 of the Longitudinal Ageing Study in India. Multivariable logistic regression is used to explore the association between CVDs and major depressive disorder among older men and women. The Karlson-Holm-Breen (KHB) method is used to examine the mediation effects of self-rated health and functional difficulties in the observed associations.

Results

Overall, 5.08% of the older adults had multiple CVDs. Older women (9.71%) had a higher prevalence of major depressive disorder compared to men (7.50%). Multiple CVDs were associated with greater odds of major depressive disorder after adjusting the potential covariates (adjusted odds ratio [AOR]: 1.49; 95% confidence interval [CI]: 1.10-2.00). Older men with multiple CVDs had a greater risk of major depressive disorder (AOR: 1.64; 95% CI: 1.05-2.57) relative to women with CVDs (AOR: 1.39; 95% CI: 0.93-2.08). The association between multiple CVDs and depression was mediated by self-rated health (34.03% for men vs. 34.55% for women), ADL difficulty (22.25% vs. 15.42%), and IADL difficulty (22.90% vs. 19.10%).

Conclusions

One in five older Indians with multiple CVDs reports major depressive disorder, which is three times more common than the prevalence of depressive disorder in older adults without CVDs. This association is attenuated by self-rated health and functional limitations. Moreover, these associations are more pronounced in older men relative to older women. These findings depart from prior inferences that men with CVDs are less psychologically distressed than their female counterparts. Moreover, the findings underscore the importance of gender-specific approaches to interventions and therapeutics for CVD-related mental health.

The Landscape of Perception: Racial Differences in How Disability Is Viewed Among Older-Adult Cancer Survivors

This paper compares disability perceptions of Black with white older cancer survivors' to document racial disparities in these perceptions and the factors that contribute to them. The data are from a randomly selected tumor registry sample of 321 older adult cancer survivors from an NCI funded study. OLS regression models of disability perceptions, nested by race, examined the effects cancer and non-cancer health factors along with important covariates. Black older adult cancer survivors perceived themselves to be more disabled than did white survivors. Multivariate analyses showed a strong relationship between functional difficulties and disability perceptions for both Black and white survivors. However cancer-related factors such as continuing symptoms of the illness or treatment were relatively more important for Blacks. The findings suggest that race and cancer are both important factors in our understanding of disability in later life. These findings can then inform clinical best practices among minority older adults.

Impacts of Social Participation on Self-Rated Health of Aging Women in China: With a Mediating Role of Caring for Grandchildren

Population aging is a global challenge and the degree of population aging is continuing to deepen in China. Under the active aging policy framework by WHO, great importance has been attached to aging women and participation is emphasized for the well-being of the elderly. This study aimed to investigate the relation between social participation and self-rated health status of aging women in China and whether caring for grandchildren mediated such an association. Adopting data from the 2018 China Health and Retirement Longitudinal Study (CHARLS), this study used Oprobit regression, propensity score matching (PSM), and instrument variable regression to estimate the effects. The result showed that there was a positive association between social participation and self-rated health among aging women in China, and social activities that directly made contributions to others had the most significant impacts on self-rated health. Furthermore, the mediator analysis confirmed that caring for grandchildren played a role between social participation and self-rated health. In conclusion, to deal with population aging challenges, the society should recognize the value of intergenerational care for aging women and the government need to strengthen policy supports to guarantee platforms and opportunities for the elderly to participate in social activities.

Older Korean Americans' concern about Alzheimer's disease: the role of immigration-related factors and objective and subjective cognitive status

Objectives: The present study examined the associations between immigration-related factors and objective and subjective cognitive status with older Korean Americans' concern about developing Alzheimer's Disease (AD). It was hypothesized that (1) AD concern would be associated with immigration-related factors and (2) self-rated cognitive status would mediate the relationship between cognitive performance (Mini Mental State Examination (MMSE) scores) and concern about AD.Method: Using data from the Study of Older Korean Americans (n = 2061, mean age = 73.2; 66.8% female), the direct and indirect effect models were tested.Results: Korean American immigrants with a higher level of acculturation had better cognitive performance, more positive self-ratings of cognitive status, and a lower level of concern about AD. Both poor cognitive performance and negative self-ratings of cognitive status were associated with increased concern about AD. Supporting the mediation hypothesis, the indirect effect of cognitive performance on AD concern through self-rated cognitive status was significant (bias corrected 95% confidence interval for the indirect effect = -.012, -.003).Conclusion: The mediation model not only helps us better understand the psychological mechanisms that underlie the link between cognitive status and AD concern but also highlights the potential importance of subjective perceptions about cognitive status as an avenue for interventions.

Self-rated health as a mediator between physical health conditions and depressive symptoms in older Chinese and Korean Americans

In the present study, we examined self-rated health as a mediator between physical health conditions (chronic diseases and functional disability) and depressive symptoms in older Chinese and Korean Americans. Using harmonized data (N = 5,063) from the Population Study of Chinese Elderly (PINE) and the Study of Older Korean Americans (SOKA), we tested direct and indirect effect models. In both groups, chronic diseases and functional disability were closely associated with negative ratings of health and symptoms of depression. Analyses with the PROCESS macro showed that the effect of chronic diseases and functional disability on depressive symptoms was mediated by self-rated health in both groups; the indirect effect was greater in the Korean American sample than in the Chinese American sample. These findings contribute to the understanding of the psychological mechanisms that underlie the mind–body connection and highlight the potential importance of subjective health assessment as a useful tool for health promotion.

Health-Related Quality of Life of Economically Disadvantaged African American Older Adults: Age and Gender Differences

Background: The association between age and health-related quality of life (HRQoL) is still under debate. While some research shows older age is associated with better HRQoL, other studies show no or negative association between age and HRQoL. In addition, while the association between age and HRQoL may depend on race, ethnicity, gender, and their intersections, most previous research on this link has been performed in predominantly White Middle Class. Objective: To explore gender differences in the association between age and mental and physical HRQoL in a sample of economically disadvantaged African American (AA) older adults. Methods: This cross-sectional survey was conducted in South Los Angeles between 2015 to 2018. A total number of 740 economically disadvantaged AA older adults (age ≥ 55 years) were enrolled in this study, using non-random sampling. This includes 266 AA men and 474 AA women. The independent variable of interest was age. Dependent variables of interest were physical component scores (PCS) and mental component scores (MCS), two main summary scores of the HRQoL, measured using Short Form-12 (SF-12). Gender was the moderator. Socioeconomic status (educational attainment and financial difficulty) were covariates. Linear regression models were used to analyze the data. Results: AA women reported worse PCS; however, gender did not impact MCS. In the pooled sample, high age was associated with better PCS and MCS. In the pooled sample, a significant interaction was found between gender and age on PCS, suggesting a stronger effect of age on PCS for AA men than AA women. In gender-stratified models, older age was associated with better PCS for AA men but not AA women. Older age was similarly and positively associated with better MCS for AA men and women. Conclusions: There may be some gender differences in the implications of ageing for the physical HRQoL of AA older adults. It is unclear how old age may have a boosting effect on physical HRQoL for AA men but not AA women. Future research should test gender differences in the effect of age on physical health indicators such as chronic disease as well as cognitive processes involved in the evaluation of own's health in AA men and women.

The differential impact of discrimination on health among Black and White women

Despite a large body of research examining the impact of discrimination on health, the ways in which perceived discrimination may lead to disparate health outcomes through a sense of self and system consciousness is less understood. The current paper is concerned with both mental and physical health consequences of discrimination, as well as mediating pathways among African American and White women. Indirect effects analyses examine mediating paths from discrimination to health outcomes via structural awareness and self-esteem, using data from the Women's Life Path Study (N = 237). Our findings suggest that discrimination is both directly and indirectly associated with health outcomes for both Black and White women, mediated by individual (self-esteem) and group-level (structural awareness) processes. Evidence from this study indicates that discrimination is associated with heightened structural awareness, as well as lower self-esteem - both of which are related to poorer health. Discrimination negatively affected health across three domains, although the mechanisms varied somewhat for Black and White women. Broad implications of this research for interdisciplinary scholarship on the effects of discrimination on health and health disparities are discussed.

Improving health-related quality of life in older African American and non-Latino White patients

OBJECTIVE

To compare the effect of problem-solving therapy against a health-promotion intervention (dietary practices) on health-related quality of life (HRQOL) and examine if there is a differential effect on non-Latino white patients and African American patients between the two interventions. This paper also explores participant characteristics (problem-solving style and physical functioning) as potential predictors of HRQOL.

METHODS

Secondary analysis of data from a randomized depression prevention trial involving 247 older adults (154 non-Latino white, 90 African American, 3 Asian). Participants were randomly assigned to receive either problem solving therapy for primary care (PST-PC) or coaching in healthy dietary practices (DIET).

RESULTS

Both PST-PC and DIET improved HRQOL over two years and did not differ significantly from each other. African American patients in both conditions had greater improvements in mental health-related quality of life (MHRQOL) compared with non-Latino white patients. In addition, higher social problem-solving and physical functioning were predictive of improved MHRQOL.

CONCLUSION

PST-PC and DIET have the potential to improve health-related quality of life in a culturally relevant manner. Both hold promise as effective and potentially scalable interventions that could be generalized to highly disadvantaged populations in which little attention to HRQOL has been paid.

Response shift recalibration and reprioritization in health-related quality of life was identified prospectively in older men with and without stroke

OBJECTIVES

To prospectively consider evidence for response shift (RS) in health-related quality of life (HRQL) in older men who experienced stroke or remained stroke free. RS is a change in the meaning of self-evaluation; this includes recalibration, reprioritization, and reconceptualization.

STUDY DESIGN

A cohort of 3,983 male World War II Royal Canadian Air Force recruits has been followed since 1948. There were three prospectively determined groups: stroke survivors (n = 168; mean age, 80.1 years); older stroke-free group (n = 254; mean age, 82.8 years); and younger stroke-free group (n = 323; mean age, 74.7 years). The Short Form-36 (SF-36) was used to evaluate HRQL. Longitudinal structural equation models were developed using SF-36 subscales and three latent variables. Measurement invariance over two time points for each of the three groups was evaluated to identify RS.

RESULTS

All RS models had reasonable fit: stroke [root mean square error of approximation (RMSEA), 0.069; 90% confidence interval (CI): 0.052, 0.086], older (RMSEA, 0.055; 90% CI: 0.041, 0.068), and younger (RMSEA, 0.062; 90% CI: 0.051, 0.074). Recalibration of physical function occurred in all three groups. Reprioritization of role limitations due to physical health happened in both stroke-free groups.

CONCLUSION

This study is unique in our ability to prospectively identify RS recalibration and reprioritization in HRQL in aging men with stroke and remaining free of stroke. Changes in the meaning of self-evaluation of HRQL occur not only with stroke but also in men who remain free of stroke.

Correlating perceived arrhythmia symptoms and quality of life in an older population with heart failure: a prospective, single centre, urban clinic study

AIMS AND OBJECTIVES

To determine the relationship between quality of life and perceived self-reported symptoms in an older, ambulatory, urban population living with heart failure.

BACKGROUND

While arrhythmias in older individuals with heart failure are well documented, the association between perceived arrhythmia symptoms and quality of life is not well-defined.

DESIGN

Prospective, cross-sectional single-centre study.

METHODS

A single-centre, prospective study was conducted with heart failure patients recruited from an urban outpatient cardiology clinic in the United States. Fifty-seven patients completed a baseline quality of life survey with 42 of these completing the six-month follow-up survey. Quality of life was evaluated with the SF-36v2(™) and frequency of symptoms with the Atrial Fibrillation Severity Scale. Subjects wore an auto triggered cardiac loop monitor (LifeStar AF Express(®) ) for two weeks to document arrhythmias. Data analysis utilised Spearman's rank correlation and logistic regression.

RESULTS

Baseline and six-month quality of life measures did not correlate with recorded arrhythmias. However, perceptions of diminished general health correlated significantly with symptoms of exercise intolerance, lightheadedness/dizziness, palpitations and chest pain/pressure. By multivariable logistic regression, more severe perceived episodes, symptoms of exercise intolerance and lightheadedness/dizziness were independently associated with diminished quality of life.

CONCLUSION

Quality of life was significantly worse in patients with perceptions of severe arrhythmic episodes and in those with symptoms of dizziness and exercise intolerance.

RELEVANCE TO CLINICAL PRACTICE

The findings of this study indicate that symptomatic heart failure patients suffer from poor quality of life and that interventions are needed to improve quality of life and decrease symptom severity. Nurses who care for heart failure patients play an essential role in symptom evaluation and management and could significantly improve overall quality of life in these patients by carefully evaluating symptomatology and testing interventions and educational programmes aimed at improving quality of life.

Diabetes and depressive symptoms among Korean American older adults: the mediating role of subjective health perceptions

PURPOSE

In recognition of the impact of chronic diseases on mental health and the lack of research on Asian American subgroups, the present study examined subjective perceptions of health as a potential mediator in the association between diabetes and depressive symptoms in Korean American older adults.

METHODS

Multivariate analysis with data from 672 Korean American older adults in Florida explored the mediation model of health perceptions.

RESULTS

The presence of diabetes was associated with negative perceptions of health and elevated symptoms of depression. The proposed mediation model was also supported: negative perceptions of health served as an intervening step between diabetes and depressive symptoms.

CONCLUSIONS

The intervening role of health perceptions yields implications for developing health promotion interventions targeting older individuals with diabetes. Results suggest that even in the presence of chronic health conditions, mental well-being of older adults can be maintained by having optimistic beliefs and positive attitudes towards their own health.

Associations Between Social Relationships and Emotional Well-Being in Middle-Aged and Older African Americans

Social relationships may enhance emotional health in older age. The authors examined associations between social relationships and emotional health using data from the Milwaukee African American sample of the second Midlife Development in the United States (MIDUS II) study, 2005-2006 ( n = 592). Self-reports indicated good, very good, or excellent emotional health, distinguished from fair or poor. Social relationships were measured by relationship type (family or friend), contact frequency, and levels of emotional support and strain. Control variables included demographic characteristics, types of lifetime and daily discrimination, neighborhood quality, and other social factors. In adjusted results, each increase on a family emotional support scale was associated with 118% greater odds of reporting better emotional health (odds ratio [OR] = 2.18, 95% confidence interval [CI] [1.43, 3.32]). Friend emotional support also was associated with better emotional health (OR = 1.59, CI [1.07, 2.34]). Daily discrimination substantially reduced reported emotional health; family and friend support buffered this effect.
