Substantial evidence demonstrates that marriage is associated with better health outcomes and lower mortality risk. Some evidence suggests that there are gender and race/ethnicity differences between the marriage-health benefits association. However, previous studies on marriage and health have mainly focused on non-Hispanic White-Black differences. Limited information is available regarding the roles of Hispanics. The present study examined marital status, gender, and the differences between non-Hispanic Whites, non-Hispanic Blacks, and Hispanics, in health outcomes. A retrospective cohort analysis of 24,119 Hispanic, NH White, and NH Black adults admitted to a large hospital was conducted. A total of 16,661 patients identified as either married or single was included in the final analyses. Consistent with the broader literature, marriage was associated with beneficial hospital utilization outcomes. With respect to differences in these benefits, results suggest that married patients, Hispanic patients, and women, were less likely to experience in-hospital mortality. Similar effects were observed in aggregated length of stay with married Hispanic women hospitalized nearly 2 days less than their single counterparts (6.83 days and 8.66 days, respectively). These findings support existing literature that marriage is associated with health benefits, add to the emerging research of a Hispanic survival advantage, and broaden the understanding of marriage and health in terms of differences by racial/ethnicity.
