Background: Metabolic syndrome is becoming an important public health problem in affluent societies. Aim: To identify factors associated to metabolic syndrome in a Southern Chilean city. Material and methods: Using a case control design, 200 participants, aged 35 to 70 years with at least three criteria for metabolic syndrome according to the National Cholesterol Education Program (NCEP_ATPIII) and 200 subjects with less than three criteria, were studied. Both groups were compared in terms of ethnic background, educational level, family history of diabetes and coronary artery disease, menopausal status, smoking, stress and depression, physical activity, changes in body mass index in the last five years and diet. Results: Among subjects aged more than 54 years, among males and among overweight individuals, having a Mapuche origin was a risk factor with odds ratios (OR) of 7.2, 88 and 3.9 respectively. Among subjects aged more than 54 years, among women and among overweight individuals, a family history of diabetes was a risk factor with OR of 17.7, 3.2 and 3.9 respectively. Among subjects aged more than 54 years and among women a change in body mass index of more than three points was a risk factor with OR of 12.5 and 7.4, respectively. Depression also was a risk factor among subjects aged more than 54 years (OR 3.3). Regular consumption of wine was a protective factor among participants of more than 54 years, with an OR of 0.17. Conclusions: The risk factors for metabolic syndrome detected in this group of participants, were having a Mapuche origin, a family history of diabetes mellitus and depression. Wine consumption was associated with a lower risk.
