Summary

The Quebec Family Study (QFS) is an observational study that was planned to investigate the role of genetic factors in physical fitness, body composition, risk factors for common disease and health-related behaviour.

Detailed description

The Quebec Family Study was an observational study with three cycles of data collection between 1978 and 1992. During the first cycle of data collection (Phase 1: 1978-1982), a total of 1,650 subjects from 375 families were recruited.

During the third cycle (Phase 3: 1998-2002), 204 subjects from phase 1 were tested a third time, 113 subjects from phase 2 were tested a second time and 194 new subjects from 44 families were recruited.
