Abstract:

In this study, we examined rates of insomnia and co-occurring unhealthy alcohol use in a national sample of women Veterans age 50?years and older. We further explored associations between sociodemographic measures, insomnia-related clinical characteristics, and unhealthy alcohol use, and analyzed whether women with insomnia were more likely to report unhealthy alcohol use. Study aims were evaluated using national Veterans Health Administration (VA) electronic health records data from VA''s Corporate Data Warehouse. Data were extracted for women Veterans = 50?years old with = 1 VA primary care visit in each study year (2018: 3/11/18-3/10/19; 2020: 3/11/20-3/10/21; 2022: 3/11/22-3/10/23). Cases of insomnia were identified via diagnostic codes and prescription medications for insomnia. Unhealthy alcohol use was identified via Alcohol Use Disorders Identification Test-Consumption screening scores indicating unhealthy alcohol use. Annual sample sizes ranged from 240,420-302,047. Over the study timeframe, insomnia rates (diagnosis or medication) among women = 50?years old ranged from 18.11-19.29%; co-occurring insomnia and unhealthy alcohol use rates ranged from 2.02-2.52%. Insomnia and unhealthy alcohol use rates were highest among women aged 50-59?years old. Depression and physical health comorbidities were consistently associated with insomnia; associations by race and ethnicity were less consistent. Compared to women without insomnia, women Veterans with either concurrent or unremitting insomnia were more likely to endorse unhealthy alcohol use. Findings signal a potential need for assessment and preventative efforts aimed at addressing insomnia and unhealthy alcohol use among women Veterans.
