Religion, in both its personal and institutional forms, is a significant force influencing the health of populations across the life course. Decades of research have documented that expressions of faith and the practice of spiritual pursuits exhibit significantly protective effects for physical and mental health, psychological well-being, and population rates of morbidity, mortality, and disability. This finding has been observed across sociodemographic categories, across nations and cultures, across specific disease outcomes, and regardless of one’s religious affiliation. A salutary religious effect on health and well-being is especially apparent among older adults, but is also observed across generations and age cohorts. Moreover, this association has been persistently found for various religious indicators, including attendance at worship services, prayer and other private practices, subjective feelings of religiosity, and numerous measures of religious behaviors, attitudes, beliefs, and experiences. Finally, a protective or primary preventive effect of religion has been observed in clinical, epidemiologic, social, and behavioral studies, regardless of research design or methodology.
Faith-based organizations also have contributed to the health of populations, in partnerships or alliances with medical institutions and public health agencies, many of these dating back many decades. Examples include congregational health promotion and disease prevention programs and community-wide interventions, especially targeting the health and well-being of older congregants and those in less well-resourced communities, as well as faith–health partnerships in healthcare delivery, public health policymaking, and legislative advocacy for healthcare reform. Religious denominations and institutions also play a substantial role in global health development throughout the world, individually and in partnership with national health ministries, transnational medical mission organizations, and established nongovernmental agencies. These efforts focus on a wide range of goals and objectives, including building public health infrastructure, addressing ongoing environmental health needs, and responding to acute public health challenges and crises, such as infectious disease outbreaks. Constituencies include at-risk populations and cohorts throughout the life course, and programming ranges from perinatal care to maternal and child healthcare to geriatric medicine.
