目的和方法：在糖尿病预防计划（DPP）队列中，使用不同时间范围的问卷对来自美国27个中心的3234名年龄> 25岁的糖耐量受损（IGT）超重个体进行休闲体力活动评估。这三份问卷是可修改的活动问卷（MAQ：过去一年），低水平体力活动回忆（LOPAR;过去7天）和第三次全国健康和营养检查调查（NHANES 111;过去一个月）。结果：三种问卷所测得的休闲活动量之间存在显著相关，但MAQ与NHANES III之间的相关性更强（男性：rho = 0.52：女性：rho = 0.49：P < 0.01）比LOPAR和任何一种测量（男性：rho = 0.20，MAQ。0.24对于NHANES妇女：rho = 0。最大允许值为10，0。13为NHANES）。在DPP中，肥胖和葡萄糖耐量指标与MAQ和NHANES测定的活动水平显著相关。但不是LOPAR。由NHANES III问卷确定的DPP参与者的活动水平通常高于符合DPP资格标准的个人报告的活动水平，这些人是NHANES队列的一部分，具有相似的年龄，体重指数和种族或民族。如果DPP参与者比IGT个体的全国样本更活跃，当在不太活跃或不太积极的人群中使用DPP生活方式干预时，这将对翻译产生影响。最后，活动水平与MAQ和LOPAR之间的弱关系可能是由于它们包含不同的时间范围和不同的休闲活动组成部分。
Purpose and Methods: Leisure physical activity was assessed using questionnaires with different time frames in the Diabetes Prevention Program (DPP) cohort of 3234 overweight individuals aged > 25 yr with impaired glucose tolerance (IGT) from 27 centers across the United States. The three questionnaires were the Modifiable Activity Questionnaire (MAQ: past year), the Low-Level Physical Activity Recall (LOPAR; past 7 d), and the Third National Health and Nutrition Examination Survey (NHANES 111; past month). This provided the opportunity to examine the relationship between the three activity measures and to compare activity levels of the DPP sample with that of a national sample with IGT.Results: Leisure activity determined by the three questionnaires significantly correlated with each other, although the correlations between MAQ and NHANES III were stronger (men: rho = 0.52: women: rho = 0.49: P < 0.01) than between LOPAR and either measure (men: rho = 0.20 for MAQ. 0.24 for NHANES women: rho = 0. 10 for MAQ, 0. 13 for NHANES). In the DPP, measures of obesity and glucose tolerance were significantly correlated with activity levels determined by MAQ and NHANES. but not LOPAR. Activity levels in DPP participants determined by the NHANES III questionnaire were generally higher than those reported by individuals meeting DPP eligibility criteria who were part of the NHANES cohort for similar age, body mass index, and race or ethnicity.Conclusion: If the DPP participants were more active than a national sample of individuals with IGT, this would have implications for translation when using the DPP lifestyle intervention in less active or less motivated populations. Finally, the weak relationship between activity levels obtained with MAQ and LOPAR may result from the fact that they encompass different time frames and different components of leisure activity.
