Disability, Health Insurance and Psychological Distress among US Adults: An Application of the Stress Process

The association of current exclusive e-cigarette use and dual use of e-cigarettes and cigarettes with psychological distress among U.S. adults

This observational study examines the association of current e-cigarette use and dual use of e-cigarettes and cigarettes (dual use) with psychological distress among U.S. adults. We differentiate dual use based on the smoking frequency and compare the relationship between dual use and psychological distress to that of exclusive cigarette smoking with the same smoking frequency. Using data from the 2015-2018 National Health Interview Surveys, we analyzed adults aged 18+ (N = 55,780) who currently use e-cigarettes or/and cigarettes and have no history of using other tobacco products, and adults who never used any tobacco. Multinomial logistic regression models estimate the association of current e-cigarette use and dual use with psychological distress severity (no/mild, moderate, and severe).In the sample, 15.3% and 2.9% of adults experienced moderate and severe psychological distress. Compared to never tobacco users, current exclusive e-cigarette users and dual users who smoke daily had higher odds of moderate and severe psychological distress. Dual users who smoke nondaily had higher odds of moderate, but not severe psychological distress than never tobacco users. Compared to exclusive daily smokers, dual users with daily smoking had higher odds of moderate and severe psychological distress. Compared to exclusive nondaily smokers, dual users with nondaily smoking had higher odds of moderate but not severe psychological distress. Our findings suggest that exclusive e-cigarette use is associated with psychological distress severity. Dual use is associated with higher odds of psychological distress severity compared to never tobacco users and exclusive cigarette smoking, and this association differs by smoking frequency.

Disability, Discrimination, and Mental Health during the COVID-19 Pandemic: A Stress Process Model

Drawing on data from a community survey with a sizeable subsample of people with physical, intellectual, and psychological disabilities in the Intermountain West region of the United States (N = 2,043), this investigation examined the association of social stressors stemming from the COVID-19 pandemic with ableism or disability-related discrimination. We further assessed the significance of these associations for variation by disability status in psychological well-being with a moderated mediation analysis. Study findings provide clear evidence that greater pandemic-related stressor exposure was associated with greater discrimination, which in turn increased the psychologically distressing aspects of the pandemic for people with disabilities relative to people without disabilities. This set of findings challenges us to think about how we engage in research concerning ableism and the proliferation of macro-level stressors such as those associated with the COVID-19 pandemic. The findings also support the application of a minority stress model in addressing mental health contingencies among people with disabilities-in this case, in examining the pandemic's psychological impact.

Machine-Learning-Aided Self-Powered Assistive Physical Therapy Devices

An expanding elderly population and people with disabilities pose considerable challenges to the current healthcare system. As a practical technology that integrates systems and services, assistive physical therapy devices are essential to maintain or to improve an individual's functioning and independence, thus promoting their well-being. Given technological advancements, core components of self-powered sensors and optimized machine-learning algorithms will play innovative roles in providing assistive services for unmet global needs. In this Perspective, we provide an overview of the latest developments in machine-learning-aided assistive physical therapy devices based on emerging self-powered sensing systems and a discussion of the challenges and opportunities in this field.

Depression, functional disability, and accessing health care among older Ghanaians and South Africans: a comparative study based on WHO study on global ageing and adult health (SAGE)

OBJECTIVES

The study explored the association and variabilities between mild depression, functional disability, and healthcare access among older Ghanaians and South Africans.

METHOD

The data used in this study was based on the Cross-sectional wave 1 (2007-2010) data from WHO's Study on Global Ageing and Adult Health (SAGE). Using multiple binary logistic regression, responses from a sample of 4558 Ghanaians and 3076 South Africans were analyzed to investigate hypothesized patterns.

RESULTS

The proportion of mild depression (MD) is 6.0 % and 7.53% for older Ghanaians and older South Africans, respectively. At 95% Confidence Interval, increased severity (mild and high levels) of functional disability are associated with increased odds of MD in Ghanaian and South African older adults. Apart from South African older adults, older Ghanaians in the study who do not receive healthcare when needed have increased odds of MD than those who do. Sociodemographic and socioeconomic factors are also associated with MD.

DISCUSSION

An untreated, persistent MD may lead to worse conditions with fatal outcomes. Since mental health care is lacking in both countries, this study may inform policies directed towards support for formal and informal long-term care, and healthcare access to reduce the risks of depression.

The Compounded Burden of Poverty on Mental Health for People with Disabilities

Using 2008-2017 National Health Interview Survey data (N = 127,973), we investigated the relationship between income and psychological distress, measured by the Kessler 6 (K6) Scale (range 0-24), net of education, employment, and other sociodemographic characteristics. Regression models allowed the association to differ by disability status and number of disabilities. Lower income predicted higher psychological distress for those with and without disabilities. However, the adverse association was stronger among people with disabilities. Compared to those with incomes at least four times the poverty threshold, poor individuals with disabilities scored 2.81 (95% CI = 2.55,3.67) points higher on the K6 Scale versus 0.58 (95% CI = 0.48,0.69) points higher for those without disabilities. Differences in associations by number of disabilities were not statistically significant. Nonetheless, those with multiple disabilities were still at increased risk of distress because they were disproportionately poor. People with disabilities who are poor are particularly disadvantaged and should be prioritized in outreach efforts.

Private Insurance and Mental Health among Older Adults with Multiple Chronic Conditions: A Longitudinal Analysis by Race and Ethnicity

Older adults with multiple chronic conditions have a higher risk than those without multiple conditions of developing a mental health condition. Individuals with both physical and mental conditions face many substantial burdens. Many such individuals also belong to racial and ethnic minority groups. Private insurance coverage can reduce the risks of developing mental illnesses by increasing healthcare utilization and reducing psychological stress related to financial hardship. This study examines the association between private insurance and mental health (i.e., depressive symptoms and cognitive impairment) among older adults in the United States with multiple chronic conditions by race and ethnicity. We apply a multivariate logistic model with individual fixed-effects to 12 waves of the Health and Retirement Study. Among adults with multiple chronic conditions in late middle age nearing entry to Medicare and of all racial and ethnic groups, those without private insurance have a stronger probability of having depressive symptoms. Private insurance and Medicare can mediate the risk of cognitive impairment among non-Hispanic Whites with multiple chronic conditions and among Blacks regardless of the number of chronic conditions. Our study has implications for policies aiming to reduce disparities among individuals coping with multiple chronic conditions.

FUNCTIONAL LIMITATION AND DEPRESSIVE SYMPTOMATOLOGY: CONSIDERING PERCEIVED STIGMA AND DISCRIMINATION WITHIN A STRESS AND COPING FRAMEWORK

This study examines whether perceived stigma and discrimination moderate the associations between functional limitation, psychosocial coping resources, and depressive symptoms among people with physical disabilities. Using two waves of data from a large community study including a representative sample of persons with physical disabilities (N=417), an SEM-based moderated mediation analysis was performed. Mediation tests demonstrate that mastery significantly mediates the association between functional limitation and depressive symptoms over the study period. Moderated mediation tests reveal that the linkage between functional limitation and mastery varies as a function of perceived stigma and experiences of major discrimination and day-to-day discrimination, however. The implications of these findings are discussed in the context of the stress and coping literature.
