Religious Attendance and Physical Health in Later Life: A Life Course Approach.

Existing research on the life course origins of adult health has extensively examined the influence of childhood socioeconomic conditions, family structure, and exposure to trauma. Left unexplored are the potential long-term health effects of sociocultural exposures, such as religiosity at earlier phases of the life course. Integrating life course models of health with literature on the health-protective effects of adult religiosity, we consider how adolescent and midlife religiosity combine to structure the physical health profiles of adults past age 50. Using more than 35 years of representative data from the National Longitudinal Survey of Youth 79 (NLSY79), we found that the stability of frequent religious practice over time was associated with better health composite scores and lower disease burden. Causal mediation analyses revealed that part of this association is driven by a lower risk of smoking for consistent, frequent attenders. Adulthood religiosity also mediated the relationship between frequent early-life religious attendance and health.
