从1960年至1980年对美国人口进行的四次全国健康检查调查的数据进行了分析，以确定长期趋势肥胖的白色和黑人青少年和年轻人的性别。在1960年至1962年的第一次调查中，使用第50、75和85次调查确定的分界点将体重指数分为四个级别。这些体重类别的加权比例的人进行了测定，并开发了统计模型来描述长期趋势和种族的影响。在12-17岁的白色或黑人青年中没有发现一致的长期趋势。在18-34岁的白色或黑人年轻男性中没有发现肥胖的显著长期趋势。无论是白色和黑人成年女性，有显着的长期增长的成年女性的比例在每个连续较重的类别的身体质量指数。这些增加是相同的白色和黑人成年女性的对数赔率规模，但黑人成年女性已经显着较重的第一次调查。这种竞争效应持续了整个时间间隔。
Data from four National Health Examination Surveys conducted of the US population from 1960 to 1980 were analyzed to determine secular trends in obesity for white and for black adolescents and young adults of both sexes. Body mass index was categorized into four levels using cut points determined by the 50th, 75th, and 85th percentiles at the first survey in 1960–1962. The weighted proportions of persons in these body mass categories were determined, and statistical models were developed to describe secular trend and race effects. No consistent secular trends were found for white or black youths aged 12–17 years. No significant secular trends in obesity were found for white or black young males aged 18–34 years. Both for white and for black adult females, there were significant secular increases in the proportion of adult females in each of the successively heavier categories of body mass index. These increases were identical for white and for black adult females on the log-odds scale, but black adult females were already significantly heavier at the first survey. This race effect persisted throughout the entire time interval.
