Our sample consists of two unique groups of men recruited in the 1930's and 1940's:

 

1. Harvard Cohort - Grant Study

The participants for this study were chosen when they were around 19 years old. It is a group of 268 Caucasian men from the Harvard classes of 1939-1944. 

 

2. Boston Cohort - Glueck Study

456 Caucasian men from the neighborhoods of Boston were selected at ages between 11-16 by Harvard Law School professors Sheldon and Eleanor Glueck.
