Secular trends in the relationship of body mass index (BMI) and skinfold thickness to educational and income levels were examined for white and black men aged 18-34 y over the period 1960-80 with data from three successive national surveys: NHES Cycle I, NHANES I, and NHANES II. Statistical models were fitted to assess the variability in mean BMI over time within levels of education or income. There were few secular changes in mean BMI. In both white and black men a secular change from a slight positive association between mean BMI and education to a negative association was characterized chiefly by an increase in mean BMI at the lowest educational level. A slight positive association between income level and mean BMI persisted almost unchanged over this period. Mean BMI was similar for black and white men. These findings are compared and contrasted with those from a similar study for young women.
利用来自三次连续全国性调查（国家健康检查调查第一轮、国家健康与营养检查调查第一轮和国家健康与营养检查调查第二轮）的数据，研究了1960年至1980年期间18至34岁白人男性和黑人男性中体重指数（BMI）及皮褶厚度与教育水平和收入水平之间关系的长期趋势。采用统计模型来评估教育水平或收入水平内平均BMI随时间的变化情况。平均BMI几乎没有长期变化。在白人男性和黑人男性中，平均BMI与教育之间从轻微正相关到负相关的长期变化主要表现为最低教育水平下平均BMI的增加。在此期间，收入水平与平均BMI之间的轻微正相关几乎保持不变。黑人男性和白人男性的平均BMI相似。将这些发现与一项针对年轻女性的类似研究结果进行了比较和对比。
