Does sleep disturbance mediate the relationship between perceived racism and depressive symptoms? Context: To examine the effects of racism on sleep disturbance and depression and to examine whether sleep disturbance mediates the effects of racism on depression. Cross-sectional questionnaire study. Community. 168 Hispanic-American immigrants, 45% female, average age 33 years, average length of time living in the United States was 5 years. The Perceived Racism Scale for Latinos, the Pittsburgh Sleep Quality Index, and the Center for Epidemiologic Studies-Depression (CES-D) Scale. Using hierarchical linear regression analyses, perceived racism was related to increased sleep disturbance (b=.21, P<.01) and higher levels of depressive symptoms (b=.24, P<.01). When sleep disturbance was included in the regression equation, perceived racism was no longer a significant predictor of depressive symptoms (b=.10, nonsignificant), indicating that sleep disturbance mediated the relationship between perceived racism and depressive symptoms.
