摘　　要：目的调查和分析中国南方轻体力劳动成人维持能量零平衡的膳食能量摄入水平。方法随机抽样选择32名从事轻体力劳动的南方健康成人(18～45岁)作为研究对象,在2个月内取相等间隔时间观察所选对象进餐情况和体重变化(使观察日覆盖星期一到星期天)。通过食物称重法准确记录各对象食堂内用餐情况,并用24小时回顾法收集各对象食堂外所摄入食物。用《中国食物成分表2002》计算各对象平均每天实际能量摄入量,并结合体重变化,使用能量平衡原理进行校正。结果总体对象维持能量零平衡的能量平均摄入量为(8.895±1.535)MJ/d,其中男性(10.070±1.150)MJ/d,女性(7.719±0.765)MJ/d。结论通过连续2个月内相等间隔时间称重记录进餐所有食物的净摄入量和体重变化来分析轻体力劳动成人能量零平衡时的能量摄入量,该方法简便经济、有效可行。Objective Using an energy zero balance method to investigate and analyze the level of dietary energy intake of healthy adults in southern China,in order to provide basic data for revising Chinese energy DRIs.Methods A total of 32 healthy adults engaged in light physical activities were recruited randomly.The food intake of each subject including meals and snacks was weighed and made records at same days intervals in a period of 2 month（covering Monday to Sunday of a week）.The energy intake was calculated and adjusted with the change of body weight according to the energy balance principle.Results The average total energy intake of subjects in energy zero balance was（8.895±1.535）MJ/d,（10.070±1.150）MJ/d for male and（7.719±0.765）MJ/d for female.Conclusion The energy intake of healthy adults at zero balance could be measured at same days intervals within a 2 month period.The method was convenient,economical,available and practicable.
