Metabolic syndrome and socioeconomic status in France: The French Nutrition and Health Survey (ENNS, 2006-2007)

The main objective was to estimate, in France, the prevalence of metabolic syndrome (MetS) and to investigate the association between socioeconomic position and MetS. The French National Nutrition and Health Survey (ENNS) cross-sectional national multistage sampling was carried out in 2006-2007. Data collection included waist circumference and blood pressure measurements, blood sample and sociodemographic and medication information. The prevalence of MetS was assessed using several definitions, including Joint Interim Statement (JIS). Association with sociodemographic covariates was assessed using logistic regression models. Among the 1,856 participants 18-74 years of age, MetS prevalence was found to vary from 14.6 % (National Cholesterol Education Program definition) to 21.1 % (JIS), with no difference between genders. After adjustment, risk of MetS increased with age in both men and women. In women, MetS risk was inversely associated with education level. Risk of MetS was higher in men born outside France than in French-born males. MetS prevalence appeared to be lower in France than in most industrialised countries. The promoting of public health measures to reduce MetS, for example, lifestyle changes, is of utmost importance, particularly among less favourable socioeconomic categories and among migrants.
