Obesity in Castile and Leon, Spain: epidemiology and association with other cardiovascular risk factors.

A cross-sectional study of obesity in a random sample of 4012 individuals aged ≥ 15 years in Castile and Leon, Spain, was carried out. The prevalence of obesity (i.e. a body mass index ≥ 30 kg/m²) and abdominal obesity (i.e. a waist circumference > 102 cm in males or > 88 cm in females) was determined and associations between both types of obesity and other cardiovascular risk factors were investigated. The overall prevalence of obesity was 21.7% (95% confidence interval [CI], 20.3%-23.2%): it was higher in women, at 23.2% (95% CI, 20.9%-25.5%), than in men, at 20.4% (95% CI, 18.0%-22.7%). The prevalence of abdominal obesity was 36.7% (95% CI, 34.6%-38.9%): again it was higher in women, at 50.1% (95% CI, 47%-53.1%) than in men, at 22.8% (95% CI, 20.3%-25.2%). Associations were found between obesity and all classic cardiovascular risk factors, except smoking. The 10-year Systematic Coronary Risk Evaluation (SCORE) and Framingham risk scores were higher in obese individuals.
