Invited Commentary: Explaining the Relationship Between Attending Worship Services and Mortality-A Brief Excursion Into the Contribution of Social Relationships in Religious Institutions.

In this issue of the Journal, VanderWeele et al. (Am J Epidemiol. 2017;000(00):000-000) report that more frequent attendance at worship services is associated with a lower mortality risk. However, the underlying processes that might explain this relationship were not discussed fully. A problem arises because the potentially beneficial association between attending worship services and mortality risk may be due to a number of different factors. At least part of the explanation may be found by turning to social relationships that arise in religious institutions. Within this context, there are potentially important benefits of providing social support to others. Support can be provided in several ways that involve potentially important health-related associations. In this commentary, I briefly examine the possible relationships between religious social support systems and other dimensions of congregational life and health. In-depth conceptual analyses are needed to move research in religious involvement and mortality to the next level.
