The team looked at data from 5,000 people taking part in the long-term Nurses’ Health Study II and its next generation Growing Up Today Study (GUTS). They were interested in whether the frequency with which a child/teen attended religious services with their parents or prayed/meditated on their own was correlated with their health and mental health as they grew into their 20s. The young people were followed for anywhere from eight to 14 years.

It turned out that those who attended religious services at least once a week as children or teens were about 18% more likely to report being happier in their 20s than those who never attended services. They were also almost 30% more likely to do volunteer work and 33% less likely to use drugs in their 20s as well.
