A cross-sectional study carried out in 2006-2007, whose primary objective was to describe the dietary intake, physical activity and sedentary lifestyle, and nutritional status of children (aged 3-17) and adults (aged 18-74) living in mainland France. Its secondary objectives were to describe the prevalence of diabetes, metabolic syndrome, arterial hypertension and dyslipidemia, both known and unknown, as well as their nutritional risk factors and their nutritional and medication management in the adults included in the study.
The sample of people to be included was randomly selected using a three-stage sampling design: 3115 adults and 1675 children were included over one year to take into account the seasonality of behaviours, particularly diet and physical activity.
Socio-demographic data, living conditions, smoking habits, physical activity and sedentariness, medication use, medical history, etc. were collected by means of questionnaires, either face-to-face or completed by the participants themselves. The dietary survey consisted of 3 24-hour recalls, randomly distributed over 15 days. A clinical and biological nutritional assessment completed the dietary survey. For children, this consisted of weight and height measurements. For adults, the examination included measurements of weight, height, waist and hip circumferences, blood pressure and biological markers (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, hemoglobin, ferritin, blood glucose, creatinine, folate, vitamin D).
