Using data from the Behavioral Risk Factor Surveillance System, this study describes trends in the prevalence of overweight between 1987 and 1993 : Methods.
Data were examined from 33 states participating in an ongoing telephone survey of health behaviors of adults (n=387 704).
Self-reported weights and heights were used to calculate sex-specific prevalence estimates of overweight for each year from 1987 to 1993.
Time trends were evaluated with the use of linear regression.
Between 1987 and 1993, the age-adjusted prevalence of overweight increased by 0.9% per year for both sexes (from 21.9% to 26.7% among men and from 20.6% to 25.4% among women).
The increasing linear trend was observed in all subgroups of the population but was most notable for Black men (1,5% per year) and men living in the Northeast (1.4% per year).
Secular changes in smoking and leisure-time physical activity did not entirely account for the increase in overweight.
The prevalence of overweight among American adults increased by 5% between 1987 and 1993.
Efforts are needed to explore the causes of this adverse trend and to find effective strategies to prevent obesity.
