Midlife Satisfaction Disparities by Sexual Orientation: Findings from the Health and Retirement Study.

Midlife is a pivotal stage shaping healthy aging, and sexual minorities may face more challenges in midlife than heterosexual individuals, due to cumulative social, economic, and health disadvantages. Yet, few studies have examined how life satisfaction in midlife varies by sexual identity. Using data from the 2016 Health and Retirement Study (N=3,630), we conducted logit regressions and Karlson-Holm-Breen (KHB) decomposition analysis to examine how health-related, socioeconomic, and sociopsychological factors contribute to disparities in life satisfaction across sexual orientation groups The results show that bisexual individuals, but not gay or lesbian individuals, reported significantly lower life satisfaction than their heterosexual peers because of their poorer health status and behaviors, fewer social resources, and lower socioeconomic status.

Marital Status and Happiness During the COVID-19 Pandemic.

Objective: This study examines the long-observed marital advantage in happiness during the COVID-19 pandemic.

Background: The COVID-19 pandemic may have altered the marital advantage in happiness due to changes in social integration processes. However, this has not been explored in previous studies.

Perceived Discrimination and Incident Dementia Among Older Adults in the United States: The Buffering Role of Social Relationships.

Objectives: Recent studies have found that perceived discrimination as a chronic stressor predicts poorer cognitive health. However, little research has investigated how social relationships as potential intervening mechanisms may mitigate or exacerbate this association. Using a nationally representative sample of U.

Reconstruction of exposure to methylene diphenyl-4,4'-diisocyanate (MDI) aerosol using computational fluid dynamics, physiologically based toxicokinetics and statistical modeling.

Objectives: This study employed computational fluid dynamics (CFD), physiologically based toxicokinetics (PBTK), and statistical modeling to reconstruct exposure to methylene diphenyl-4,4'-diisocyanate (MDI) aerosol. By utilizing a validated CFD model, human respiratory deposition of MDI aerosol in different workload conditions was investigated, while a PBTK model was calibrated using experimental rat data. Biomonitoring data and Markov Chain Monte Carlo (MCMC) simulation were utilized for exposure assessment.

Unpacking Intersectional Inequities in Flu Vaccination by Sexuality, Gender, and Race-Ethnicity in the United States.

Health care research has long overlooked the intersection of multiple social inequalities. This study examines influenza vaccination inequities at the intersection of sexuality, gender, and race-ethnicity. Using data from the 2013 to 2018 National Health Interview Survey (N = 166,908), the study shows that sexual, gender, and racial-ethnic identities jointly shaped flu vaccination.
