We examined social ecological predictors of health care utilization among Latina young adults during their initial year after immigration to the United States. Participants were 530 Latinas (ages 18-23) who immigrated to Miami-Dade County, Florida, 11.5 months before assessment. We used multiple logistic regression to test predictors of health care usage. Approximately 36% utilized care. Dimensions of marianismo differentially associated with usage. Usage also was more likely for participants who reported more social network attachment, better health, greater neighborhood cohesion, and possessed a job and health insurance. Findings inform interventions to increase health care usage globally among women after immigration.
