Abstract: "Context The
prevalence of obesity and overweight increased in the United States between
1978 and
1991. More recent reports have suggested continued increases but are based on
self-reported data. Objective To
examine trends and prevalences of overweight (body mass index [BMI] greater
than or equal to 25) and obesity (BMI; greater than or equal to 30), using
measured height and weight data. Design, Setting, and Participants
Survey of 4115 adult men and women conducted in 1999 and 2000 as part of the
National Health and Nutrition
Examination Survey (NHANES), a nationally representative sample of the US
population. Main Outcome Measure Age-adjusted prevalence of overweight,
obesity, and extreme obesity compared with prior surveys, and sex-, age-, and
race/ethnicity-specific estimates. Results The age-adjusted prevalence
of obesity was 30.5% in 1999-2000 compared with 22.9% in NHANES III
(1988-1994; P<.001). The prevalence of overweight also increased
during this period from 55.9% to 64.5% (P<.001). Extreme obesity
(BMI; greater than or equal to 40) also increased significantly in the
population, from 2.9% to 4.7% (P=.002). Although not all changes were
statistically significant, increases occurred for both men and women in all
age groups and for non-Hispanic whites, non-Hispanic blacks, and Mexican
Americans. Racial/ethnic groups did not differ significantly in the prevalence
of obesity or overweight for men. Among women, obesity and overweight
prevalences were highest among non-Hispanic black women. More
than half of non-Hispanic black women aged 40 years or older were obese and
more than 80% were overweight. Conclusions The increases in the
prevalences of obesity and overweight previously observed continued in
1999-2000. The potential health benefits from reduction in overweight and
obesity are of considerable public health importance."
