Measures of height, body weight, waist and hip girths are available from the Allied Dunbar National Fitness Survey and have been used to explore differences between respondents reporting differing levels of habitual physical activity. Body mass index (BMI), waist-to-hip ratio (WHR) and waist-to-height ratio were derived. Physical activity was estimated from a structured interview. The questionnaire permitted a separate estimate of levels of participation in vigorous and moderate intensity activity, as well as total energy expenditure. Each index of body composition was regressed against the measures of physical activity and other lifestyle factors. Relationships between activity and body composition measures were weak with different patterns emerging for men and women. These data suggest that it is doubtful whether changes in body composition brought about by interventions to increase population levels of physical activity will be revealed by measuring BMI. However WHR and waist-to-height ratio indices reflecting the bulk of the intra-abdominal fat stores may prove more informative.
身高、体重、腰围和臀围的测量数据可从联合邓巴国民健康调查中获取,并已用于探究报告不同习惯性身体活动水平的受访者之间的差异。计算得出了体重指数(BMI)、腰臀比(WHR)和腰高比。身体活动通过结构化访谈进行评估。该问卷允许分别估计剧烈和中等强度活动的参与水平以及总能量消耗。将每项身体成分指标与身体活动量和其他生活方式因素的测量值进行回归分析。活动与身体成分测量值之间的关系较弱,男性和女性呈现出不同的模式。这些数据表明,通过测量BMI来揭示因增加人群身体活动水平的干预措施而导致的身体成分变化是值得怀疑的。然而,反映腹部脂肪堆积量的WHR和腰高比指数可能更具信息量。
