摘　　要：目的采用能量平衡观察法探究我国南方轻体力活动健康成人的总能量消耗量。方法选择符合能量代谢试验条件的34名南方轻体力活动健康成人为研究对象,为其设计和制备三日循环膳食,用称重法准确获得每日膳食实际摄入量,并用化学分析法测得膳食能量平均摄入量,结合试验期间的体重变化,得到我国南方健康成人总能量消耗量。结果采用称重-化学分析法测得膳食能量平均摄入量为(8424±1616)kJ/d[(2013±386)kcal/d],其中男性(9990±798)kJ/d[(2388±191)kcal/d],女性(7032±384)kJ/d[(1681±92)kcal/d]。16天的试验期间体重平均减轻0.02kg,其中男性体重平均增长0.15kg,女性体重平均减轻0.17kg,根据成人能量平衡原理最后计算得出我国南方健康成人总能量消耗量为(8468±1762)kJ/d[(2024±421)kcal/d],其中男性为(9680±1759)kJ/d[(2314±420)kcal/d],女性为(7391±827)kJ/d[(1767±198)kcal/d]。结论我国南方轻体力劳动健康成年男性总能量消耗量约为9680±1759kJ/d[(2314±420kcal/d)],女性约为7391±827kJ/d[(1767±198kcal/d)],与2000年制定的男、女性能量推荐值2400kcal和2100kcal相比,该研究男性测量值比其RNI值低86kcal,女性测量值比其RNI值低333kcal。Objective To measure the energy expenditure of healthy adults engaged in light activities in southern China,and to provide reference database for revising Chinese RNI.Methods Thirty four healthy adults eligible for the energy metabolic experiment were selected.A 3-day recycled dietary prescription was designed.The food intake of all foods per person per meal were weighed and recorded,and the energy intake from diets was determined by chemical analysis.The energy expenditure was calculated by combining the change of body weight and dietary consumption.Results The average energy intake was（8424±1616）kJ/d [（2013±386）kcal/d],which was（9990±798）kJ/d [（2388±191）kcal/d] for men and（7032±384）kJ/d [（1681±92）kcal/d] for women.The average change of body weight of all subjects in 16 days was reduced 0.02kg,the men increased 0.15kg,and the women decreased 0.17kg.According to the energy balance principle,the ultimate energy expenditure of healthy adults in southern China was（8468±1762）kJ/d [（2024±421）kcal/d],the men was（9680±1759）kJ/d [（2314±420）kcal/d],and the women was（7391±827）kJ/d[（1767±198）kcal/d].Conclusions The energy expenditure of healthy adult male engaged in light activities in southern China was 9680±1759kJ/d [（2314±420kcal/d）],and that of female was 7391±827kJ/d[（1767±198kcal/d）].The energy expenditure of men and women measured in this study were 86kcal and 333kcal lower than the Chinese energy RNI（2400kcal and 2100kcal） established in 2000.
