[Prevalence of obesity and cardiovascular comorbidity associated in patients included in the IBERICAN study]

To analyse the prevalence of obesity and its association with other cardiovascular risk factors and cardiovascular disease in a sample of patients from the (Identification of the Spanish population at cardiovascular and renal risk) IBERICAN study.

Analysis of the inclusion visit of the first 5,013 patients of the IBERICAN longitudinal, observational, and multicentre study in which individuals aged 18 to 85 years were included in Primary Care Clinics in the different regions of Spain. In this work obesity was defined as a body mass index ≥ 30kg/m².

The prevalence of obesity was 35.7% (95% CI: 35.0-36.4%), of which 36.6% were men and 34.9% were women (P=0.214), and significantly increasing with age (0.001). The obesity had the associated higher prevalence of hypertension (62.8% vs. 39.4%, P<001), dyslipidaemia (56.9% vs. 47.1%, P<0.001), sedentary lifestyle (40.6% vs. 24.6%, P<.001), diabetes (27.5% vs. 14.8%, P<.001), hyperuricaemia (23.6% vs. 12.7%, P<.001), subclinical organ injury (33.7% vs. 26.5%, P<.001) and cardiovascular disease (21.2% vs. 15.3%, P<.001). The multivariate analysis showed that the variables associated with obesity were: arterial hypertension (P<.001), hyperuricemia (P<.001), sedentary lifestyle (P<.001), diabetes mellitus (P<0.001), age (P<0.001), low educational level (P<0.001) and lower consumption of tobacco (P<0.001).

The analysis of the IBERICAN study shows that approximately one third of the analysed population meets criteria of obesity and cardiovascular risk factors. Target organ damage and cardiovascular disease were more frequent in obese patients.
