    Objectives

    This study estimated the amount of weight change in a biracial cohort of young adults and the separate components attributable to time-related and aging-related changes. as well as identified possible determinants of weight change.

    Methods

    In this population-based prospective study of 18-to 30-year-old African-American and White men and women, body weight and prevalence of overweight were measured from 1985/86 to 1992/93.

    Results

    Average weight increased over the 7 years. increases ranging from 5.2 kg (SE=0.2, n=811) in White women to 8.5 kg (SE=0.3, n=882) in African-American women.

    Significant time-related increases in weight, ranging from 2.0 kg (SE=1.0) in White women to 4.8 kg (SE=1.0, n=711) in African-American men. accounted for 40% to 60% of the average total weight gain.

    Aging-related increases were also significant. ranging from 2.6 kg (SE=0.8, n=944) in White men to 5.0 kg (SE=1.1) in African-American women.

    The prevalence of overweight increased progressively in each group.

    Decreased physical fitness was most strongly associated with weight gain in both sexes.

    Conclusions

    The observed dramatic time-related weight gains. most likely due to secular (period-related) trends, are a serious public health concern.
