... unicipality of Ain Fakroun, 12 urban districts are drawn. In each household 1-4 between 18 and 75 people were randomly. In total 273 households corresponding to a set of 1091 people surveyed. For recruiting, the anthropometric measurements are made, arterial pressions, blood samples are taken, anticoagulants in heparinized tubes, on fasting subjects, intended for a lipid profile and blood glucose. In addition, data collections were carried out through an interview. Results: The data results are shown that; more than 1/3 of the population is excess weight (BMI > 25 kg/m²). The prevalence increased significantly (p = 0.0014) among young adults and then gradually decreases with age and fall markedly among seniors over 60 years. The frequency of overweight patients is 36.41%; it is relatively identical in both sexes. However, the proportion of obese is predominant (60.98%) with obesity class I predominant in both sexes while severe obesity (BMI ≥ 40 kg/m²) is more common in women. The result on the association between BMI and vascular risk factors reinforce conventional notions. Conclusion: The descriptive point of view at men as well at women, the overweight seems due to social, biological and environmental factors.
