# Differential Impact of Natural Disasters on Mental Health Across Racial and Ethnic Groups

## TL;DR

This study finds that natural disasters have a stronger negative impact on mental health for older Black individuals compared to older White individuals, highlighting the need for targeted mental health support.

## Contribution

The study provides novel evidence on racial disparities in mental health outcomes following natural disaster exposure using a large, nationally representative sample.

## Key findings

- Natural disaster exposure is associated with higher depression and anxiety levels in older adults.
- Older Black individuals show significantly higher mental health impacts compared to older White individuals.
- The association between disaster exposure and mental health is not significant for older Hispanic individuals.

## Abstract

Natural disasters are increasing in both frequency and severity, affecting 224.1 million people globally each year. These events have profound consequences for public health and well-being, as exposure to natural disasters has been found to be associated with poor mental health outcomes. The adverse impact of natural disasters may vary across racial and ethnic groups due to their differences in socioeconomic status, trauma exposure, and access to healthcare. However, existing literature primarily focuses either on a single racial and ethnic group or broadly on affected populations, limiting our understanding of how natural disaster exposure affects mental health across diverse racial and ethnic groups. This study examines whether lifetime experience of natural disasters is associated with poor mental health and whether the impact differs across racial and ethnic groups, utilizing data from the 2010/2012 Health and Retirement Study (N = 13,817). A series of weighted ordinary least squares regression models were estimated, adjusting for sociodemographic characteristics. The results indicate that natural disaster exposure is associated with higher levels of depression and anxiety, with a greater impact observed among older Blacks (depression: β=.52, p<.001; anxiety: β=.19, p<.001) compared to older Whites (depression: β=.11, p<.05; anxiety: β=.07, p<.001). The association was not significant among older Hispanics (depression: -.20, p=.45; anxiety: .02, p=.82). Our findings align with previous research indicating greater vulnerability to natural disasters among racial and ethnic minorities. They underscore the need for tailored policy and intervention strategies for these communities, such as culturally informed mental health care and disaster preparedness and response plans.
