To evaluate the relationship of body composition with physical activity and other anthropometric factors, a group of 437 healthy Chinese men and women were recruited. Body composition was measured using the bioelectric impedance technique. Levels of physical activity (LPA) were classified as light, moderate and heavy. Anthropometric factors evaluated included body mass index (BMI), ponderal index (PI), waist-to-hip ratio (WHR), triceps skinfold thickness (TSF), mid-arm circumference, mid-forearm circumference, arm muscle circumference (AMC) and arm muscle area (AMA). Sex was found to be highly associated with body composition, with females having a higher percentage of body fat and males having a higher percentage of body lean mass. This gender difference was independent of age, physical activity or other anthropometric factors. An increased level of physical activity was associated with higher body lean mass and lower body fat. Sex, LPA, TSF, PI and WHR were all entered into the regression equations to estimate body composition. Sex and physical activity have an independent effect on body composition and the commonly used estimators for adiposity and fat distribution such as BMI, PI, TSF and WHR are closely correlated with body composition.
为评估身体成分与身体活动及其他人体测量学因素之间的关系，招募了437名健康的中国男性和女性。使用生物电阻抗技术测量身体成分。身体活动水平（LPA）分为轻度、中度和重度。评估的人体测量学因素包括体重指数（BMI）、体质指数（PI）、腰臀比（WHR）、肱三头肌皮褶厚度（TSF）、上臂中部周长、前臂中部周长、上臂肌肉周长（AMC）和上臂肌肉面积（AMA）。发现性别与身体成分高度相关，女性的体脂百分比更高，男性的瘦体重百分比更高。这种性别差异独立于年龄、身体活动或其他人体测量学因素。身体活动水平的提高与更高的瘦体重和更低的体脂相关。将性别、LPA、TSF、PI和WHR全部纳入回归方程以估计身体成分。性别和身体活动对身体成分有独立影响，常用的肥胖和脂肪分布估计指标如BMI、PI、TSF和WHR与身体成分密切相关。
