ObjectiveBody fatness and fat distribution are widely accepted as coronary heart disease risk factors. In this study, we have evaluated the contribution of generalized adiposity, assessed by body mass index (BMI), to carotid atherosclerosis, in participants with or without metabolic syndrome (MetS).MethodsWe have analysed 840 female and 1002 male participants in a regional Cardiovascular Disease Prevention Campaign. Blood glucose and lipids were analysed by standard methods. According to BMI, calculated as weight (in kilograms)/height (in square metres), participants were divided into normal weight (BMI <25 kg/m2), overweight (BMI between 25 and 29.9 kg/m2) and obese (BMI>29.9 kg/m2). Carotid atherosclerosis was evaluated by echo Doppler.ResultsBlood pressure, waist circumference, triglycerides and glucose were significantly higher, and high-density lipoprotein was lower, in overweight and obese participants, compared with normal weight. MetS was more frequent among obese and overweight than normal-weight participants (51.7 vs. 21.5 vs. 9.8%, respectively). The prevalence of carotid atherosclerosis was 45.29% in participants with MetS, significantly higher than in participants without MetS (33.04%, P<0.0001), but it was similar across the three weight categories. Furthermore, in multiple regression analyses BMI was not significantly associated with carotid atherosclerosis.ConclusionThe present findings suggest that increasing body weight favours the clustering of coronary heart disease risk factors. Overweight and obesity, however, do not independently associate with carotid atherosclerosis.
