Objectives:
Ethnic and racial health disparities have been well-documented in the scholarly literature. In recent years, evidence about time spent in physical (in)activity and its relationship to physical and mental health has also emerged. This study assesses if observed ethnic/racial health differences were associated with differences in time use.
Design:
Our analyses utilized baseline data from 510 Utah women who enrolled in one of two community-based, participatory research intervention studies between 2012 and 2015. The distinct racial/ethnic groups included African immigrants, African Americans, Latinas, Native Hawaiians/Pacific Islanders, American Indians/Alaskan Natives, and rural White, Non-Latina women. In the baseline survey, respondents reported the typical time they spent in paid employment, television/movie viewing, physical activity, food preparation/clean-up, and sleep. Cluster analysis was used to identify seven distinct patterns of time use within these five activities. We related these time use patterns along with race/ethnicity, socio-demographics, and other potentially contributing health-related factors (e.g. smoking status) to two health outcomes: (1) self-reported health status, and (2) depression.
Results:
Our time use clusters revealed heterogeneity by racial/ethnic groups, suggesting that some of the health effects that may have been previously ascribed to group membership should instead be attributed to (un)healthy patterns of time use. In particular, spending too much time in sedentary activities such as watching television/movies and too little time sleeping both linked to poor physical and mental health, independently of racial/ethnic group membership.
Conclusions:
Researchers and policy makers designing culturally sensitive physical activity health-related interventions should consider patterns of time use that are associated with poor health. Programs designed to improve sleep time and reduce sedentary television-viewing time may be as important as interventions designed to increase physical activity time. These broader patterns of time use mediated the relationships between race/ethnicity and physical and mental health for the women in our study.
