Descripción detallada
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 second cycle (Phase 2: 1989-1997), 385 subjects from 105 phase 1 families were retested and an additional 372 subject from 74 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.

Población de estudio
The QFS cohort is a mixture of random sampling and ascertainment through obese individuals.
In Phase 1 of the study, subjects were randomly selected from French-Canadian families living in the Quebec city area, In Phases 2 and 3 of the study, families with a least one obese parent and one obese offspring were recruited.
