Das analysed data extracted from the 2005-2006 and 2010-2011 waves of the National Social Life, Health and Aging Project (NSHAP). 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.
