  1. Overweight and obesity in the United States : prevalence and trends, 1960-1994.

    Article - En anglais


    To describe the prevalence of, and trends in, overweight and obesity in the US population using standardized international definitions.


    Successive cross-sectional nationally representative surveys, including the National Health Examination Survey (NHES I ; 1960-62) and the National Health and Nutrition Examination Surveys (NHANES 1 : 1971-1974 ; NHANES II : 1976-1980 ; NHANES III : 1988-94).

    Body mass index (BMI : kg/m2) was calculated from measured weight and height.

    Overweight and obesity were defined as follows : Overweight (BMI>25.0) ; pre-obese (BMI 25.0-29.9), class I obesity (BMI 30.0-34.9), class II obesity (BMI 35.0-39.9), and class III obesity (BMI = 40.0).


    For men and women aged 20-74y, the age-adjusted prevalence of BMI 25.0-29.9 showed little or no increase over time (NHES 1 : 30.5%, NHANES 1 : 32.0%, NHANES II : 31.5% and NHANES III : 32.0%) but the prevalence of obesity (BMI = 30.0) showed a large increase between NHANES II and NHANES III (NHES 1 : 12.8% ; NHANES 14.

    I% ; NHANES II, 14.5% and NHANES III, 22.5%). Trends were generally similar for all age, gender and race-ethnic groups.

    The crude prevalence of overweight and obesity (BMI 25.0) for age 20 y was 59.4% for men, 50.7% for women and 54.9% overall.

    The prevalence of class III obesity (BMI = 40.0) exceeded 10% for non-Hispanic black women aged 40-59y.


    Between 1976-80 and 1988-94, the prevalence of obesity (BMI>=30.0) increased markedly in the US. (...)
