The purpose of this study was to determine racial/ethnic differences in midlife women's sleep-related symptoms, relationships between their physical activity and sleep-related symptoms, and specific factors associated with their sleep-related symptoms in each racial/ethnic group. This was a secondary analysis of the data from 542 midlife women in the United States. The data were analyzed using descriptive statistics, χ2 tests, analysis of variance, hierarchical multiple linear regression analyses, and logistic regression analyses. The findings indicated that physical activities could improve midlife women's sleep-related symptoms, but the types of physical activities and racially/ethnically different factors associated with sleep-related symptoms need to be considered.
