People who go to church live longer. Here’s why
by Tyler J VanderWeele, Spectator:
Over the last 20 years, research has gradually accumulated suggesting that religious service attendance is associated with better physical and mental health. For example, research articles have indicated that regular religious service attendance is associated with a 30 per cent reduction in depression, a five-fold reduction in the likelihood of suicide, and a 30 per cent reduction in mortality, over 16 years of follow-up.
There have been a number of prior studies on religious service attendance and longevity. Many of these had been criticised for poor methodology, for instance allowing the possibility of reverse causation — ie, that only those who are healthy can attend services, so that attendance isn’t necessarily influencing health.
Papers recently published out of Harvard University have tried to address this concern by using repeated measurements of service attendance and health over time to control for whether changes in health preceded changes in service attendance. The associations between religious service attendance and longevity, suicide and depression were all robust. Results indicated that compared with women who never attended religious services, women who attended more than once a week had a 33 per cent lower mortality risk during the study period. Those who attended weekly had a 26 per cent lower risk and those who attended less than once a week had a 13 per cent lower risk. (The data comes from women who worked as nurses in the US, most of whom identified as Catholic or Protestant, so most of the religious services would be at churches. However, the definition encompassed a range of different places of worship.)
