# Multimorbidity and Functional Impairments in Chronic Life Stressors: Evidence From the Health and Retirement Study

## TL;DR

This study explores how chronic life stressors in older adults are linked to health issues like multiple chronic conditions and functional impairments.

## Contribution

The study identifies specific associations between multimorbidity, functional impairments, and exposure to chronic life stressors in older adults.

## Key findings

- Older adults with three or more chronic conditions are 2.68 times more likely to experience severe chronic life stressors.
- Individuals with difficulties in daily living tasks have a 2.34 times higher risk of severe chronic life stressor exposure.
- Women and those aged 65–74 are more likely to experience severe chronic life stressors compared to other groups.

## Abstract

Chronic Life Stressors (CLS) significantly impact the well-being of older adults, yet their health-related determinants remain underexplored. This study examines associations between multimorbidity, functional impairments, and CLS exposure. Using logistic regression models, we analyzed cross-sectional data from 2,822 older adults in the 2020 Health and Retirement Study. CLS was assessed across seven domains: physical-emotional stress, substance use in the family, work-related stress, financial strain, housing instability, strained relationships, and caregiving burden and was categorized as no exposure, moderate exposure (1–2 stressors), and severe exposure (3+ stressors). Multimorbidity was defined as having up to seven chronic conditions. Functional impairments included difficulties with Instrumental Activities of Daily Living (IADL) and mobility limitations. Older adults ≥75 years had lower odds of severe CLS than those aged 65–74. Women had a significantly higher risk of severe CLS exposure (OR = 1.20) than men. African American individuals had lower odds of moderate CLS (OR = 0.61) but no significant difference in severe CLS. Hispanic ethnicity was not significantly associated with CLS. Multimorbidity significantly predicted CLS; Individuals having three or more chronic conditions were 2.68 times more likely to report severe CLS exposure, and those with two conditions were 2.55 times more likely to report severe CLS exposure. Individuals with IADL difficulties had a 2.34 times increased risk of severe CLS, while those with mobility limitations had 2.07 times higher odds of severe CLS exposure. These findings underscore the need for targeted interventions to address multimorbidity and functional limitations, reducing the burden of CLS in aging populations.
