This national study was set up to collect information from older American adults (aged 57-85 at baseline). Participants completed questionnaires in their homes in which they were asked about how often they attended religious services, and whether they had a clergy member in their core social network. Information was also gathered about participants' weight and health, while saliva and blood samples were collected and later examined. > From the analysis of over 1000 men, Das found that men with higher levels of the sex hormones testosterone and dehydroepiandrosterone (DHEA) in their bodies had weaker religious ties.
