Objective To describe the relationship between weight status and prevalence of health conditions by severity of overweight and obesity in the US population. Design and Setting Nationally representative cross-sectional survey using data from the Third National Health and Nutrition Examination Survey (NHANES III), which was conducted in 2 phases from 1988 to 1994. Participants A total of 16 884 adults, 25 years and older, classified as overweight and obese (body mass index [BMI] >=25 kg/m2) based on National Institutes of Health recommended guidelines.

A graded increase in the prevalence ratio (PR) was observed with increasing severity of overweight and obesity for all of the health outcomes except for coronary heart disease in men and high blood cholesterol level in both men and women. With normal-weight individuals as the reference, for individuals with BMls of at least 40 kg/m2 and who were younger than 55 years, PRs were highest for type 2 diabetes for men (PR, 18.1 ; 95% confidence interval [Cl], 6.7-46.8) and women (PR, 12.
