The data being reported are part of an epidemiologic study of health and disease in an entire community, Tecumseh, Michigan. Approximately 1,300 males age 16-65 were classified into three groups on the basis of their habitual leisure and occupational physical activity. A blood sample was drawn one hour after a glucose challenge and analyzed for glucose concentration. A measure of body fatness (sun of four skinfolds) was also available on the men. Glucose concentration of the three physical activity groups was compared by analyses of variance within narrow age group. There was no significant relationship between glucose tolerance and habitual physical activity. There was a slight, but in some age groups significant, relationship between glucose tolerance and body fatness. The population was then divided within each age group into subgroups (thirds) by sum of skinfolds. The analysis was repeated in each age-fatness group. Glucose tolerance was better in the active men but only among the leanest subgroup of subjects.
所报告的数据是对密歇根州蒂康赛德整个社区健康与疾病进行的一项流行病学研究的一部分。大约1300名年龄在16至65岁之间的男性，根据他们习惯性的休闲和职业体力活动被分为三组。在进行葡萄糖耐量试验一小时后采集血样，并分析葡萄糖浓度。这些男性还进行了身体脂肪含量的测量（四项皮褶厚度之和）。通过在狭窄年龄组内进行方差分析，比较了三个体力活动组的葡萄糖浓度。葡萄糖耐量与习惯性体力活动之间没有显著关系。葡萄糖耐量与身体脂肪含量之间存在轻微但在某些年龄组中显著的关系。然后，在每个年龄组内，根据皮褶厚度之和将人群分为亚组（三等分）。在每个年龄-脂肪组中重复进行分析。活跃男性的葡萄糖耐量较好，但仅在最瘦的亚组受试者中如此。
