Pender’s health promotion model guided this descriptive/correlational study exploring the relationship between religiosity and health-promoting behaviors of pregnant women at Pregnancy Resource Centers (PRCs). A consecutive sample included women who knew they were pregnant at least 2 months, could read/write English, and visited PRCs in eastern Pennsylvania. Participants completed self-report surveys that examined religiosity, demographics, pregnancy-related variables, services received at PRCs, and health-promoting behaviors. Women reported they “sometimes” or “often” engaged in health-promoting behaviors, Hispanic women reported fewer health-promoting behaviors than non-Hispanic women, and women who attended classes at the centers reported more frequent health-promoting behaviors than those who did not attend classes. In separate multiple linear regressions, organized, non-organized, and intrinsic religiosity and satisfaction with surrender to God explained additional variance in health-promoting behaviors above and beyond what Hispanic ethnicity and attending classes at the PRCs explained in pregnant women at PRCs.
