ENERGY EXPENDITURE DURING DEVELOPMENT OF CHILDHOOD OBESITY

超过四分之一的美国儿童超重或肥胖。这项研究的目的是确定为什么有些孩子会肥胖，而有些孩子不会。本研究的主要目的是：1。确定变肥胖的儿童与不变肥胖的儿童相比是否有更低的能量消耗（根据无脂肪量调整）。2. 根据儿童的总能量消耗来确定他们的能量需求。该研究包括以下变量的测量：使用双标记水的总能量消耗，静息代谢率，使用双能x线吸收仪的身体成分，人体测量和使用多次24小时回忆法的饮食摄入量。佛蒙特州的研究是伯明翰阿拉巴马大学纵向队列研究的一部分。所有佛蒙特州的孩子都接受了测试。目前正在汇编和编制这些数据，以便进行统计分析。佛蒙特州的数据将与居住在阿拉巴马州伯明翰及周边地区的白人和非裔美国儿童的数据相结合。

Over one-quarter of all American children are overweight or obese. This study was designed to determine why some children become obese and others do not. The major aims of the study are: 1. To determine if children who become obese have lower energy expenditures (adjusted for fat free mass) in comparison with children who do not become obese. 2. To determine energy requirements for children based on their total energy expenditure. The study included measurement of the following variables: total energy expenditure using doubly labeled water, resting metabolic rate, body composition using dual energy x-ray absorptiometry, anthropometry, and dietary intake using the multiple-pass 24-hour recall. The Vermont portion of the study is part of a larger longitudinal cohort study based at the University of Alabama in Birmingham. All Vermont children have been tested. The data are now being compiled and prepared for statistical analysis. The Vermont data will be combined with data from both Caucasian and African-American children residing in Birmingham, Alabama and the surrounding area.
