Cross-sectional study performed in 2006-2007 with the main objective of assessing food consumption, physical activity, sedentary lifestyle and nutritional status of children (3-17 years) and adults (18-74 years) residing in metropolitan France. The secondary objectives were to describe the prevalence of diabetes (diagnosed or undiagnosed), metabolic diseases, hypertension, dyslipidemia, the nutritional risk factors for such diseases, and the medical and dietary treatments used by the adults included in the study. The study sample was randomly selected via a 3-steps random drawing: 3 115 adults and 1 675 children were enrolled over a period of 1 year, which minimised the effect of seasonal changes in behaviours, in particular those related to diet and physical activity. Data on socio-demographic characteristics, life conditions, smoking, physical activity, sedentary lifestyle, drug use and medical history were collected using questionnaires which were either self-administrered or completed during face-to-face interviews. The study also used three 24-hour food recalls randomly spread over a period of 15 days. A clinical check-up and biological tests were also part of the investigation and consisted in measuring weight and height (in children and adults), waist and hip circumference, blood pressure, total cholesterol, HDL, LDL, triglycerides, haemoglobin, ferritin, glycemia, creatinine, folate and vitamin D (in adults).
