[Development of a food frequency questionnaire to study diet and non-communicable diseases in adult population].
The study purpose was to develop a food frequency questionnaire (FFQ) to investigate potential relationships between diet and non-communicable diseases. Two hundred adults were selected among attendees at the general outpatient clinic of Heart Institute of São Paulo, Brazil. A 98-food item list was created from 24-hour recalls, based on the weighted contribution of each food to energy intake and 21 nutrients. The questionnaire represented 96.8% of energy and at least 95% of the selected nutrients consumed by the study population. Once adapted and validated, this FFQ could be used in epidemiological studies in adult population.
