Objective. To analyze the anthropometric parameters from a representative sample of Spanish adults participating in ANIBES study and the prevalence of general and abdominal obesity. Methods. This cross-sectional study focused on 1655 adults aged 18–64 years. Weight, height, and waist circumference (WC) were evaluated, and body mass index (BMI) and waist to height ratio (WHtR) were calculated. A composite index combining BMI and WHtR was designed to establish five groups with different anthropometric status. Results. The prevalence of overweight (OW) was 35.8% and that of obesity was 19.9%. Obesity (OB) was higher among men (OR 1.725, 1.415–2.104; p=0.000) and each year of age increased the risk of obesity (OR 1.054, 1.045–1.064; p=0.000). The prevalence of abdominal obesity (WHtR ≥ 0.5) was 58.4%. Only 36.1% of the population had an optimal anthropometric situation (BMI
