摘　　要：目的 测定长沙市20-29岁青年基础代谢率.方法 2015年4—5月在长沙市招募研究对象.纳入标准：年龄20-29岁;身高：男性164-180 cm,女性154-167 cm;身体健康;在过去1年内没有参加规律性体育锻炼的习惯.最终纳入81名符合条件的研究对象（男性43名,女性38名）.测量研究对象的基础代谢率、静卧代谢率和静坐代谢率,并将基础代谢率实测值与Schofield公式（修正）计算值进行比较.结果 男性基础代谢率、静卧代谢率和静坐代谢率分别为（166.10±22.09）、（174.22±24.56）和（179.54±23.35）kJ·m-2·h-1,女性分别为（137.70±20.04）、（149.79±19.25）和（167.78±26.02）kJ·m-2·h-1,男性3个指标均高于女性（P值均〈0.001）;Schofield公式（修正）计算的男女基础代谢率值分别为（160.83±3.93）和（140.29±4.18）kJ·m-2·h-1,实测值与Schofield公式（修正）计算值差异均无统计学意义（P均〉0.05）.结论 长沙市20-29岁青年基础代谢率处于全国平均水平,Schofield公式（修正）对长沙市20-29岁青年的基础代谢率预测效果较好.Objective To determine the basal metabolic rate （BMR） of young adults aged between 20-29 years old in Changsha. Methods We recruited volunteers to join in our research project from April to May, 2015. All recruited volunteers must meet the inclusion criteria： aged 20-29 years old, height between 164-180 centimeters in males and 154-167 centimeters in females , in good health condition, and with no habit of regular physical exercise in last year. Finally, 81 qualified volunteers were selected as research objects, including 43 males and 38 females. The BMR, resting lying metabolism rate and resting sitting metabolism rate of the subjects were detected, and the determined BMR was compared with the calculated results from the adjusted Schofield equation. Results The BMR , resting lying metabolism rate and resting sitting metabolism rate among males were （166.10±22.09）, （174.22±24.56）, and （179.54±23.35） kj · m-2 · h-1, respectively, which were all higher than those among females were （137.70 ± 20.04）, （149.79 ± 19.25）, and （167.78 ± 26.02） kj · m- 2 · h- 1, respectively, （P〈0.001）. The BMR of males and females calculated from the adjusted Schofield equation were （160.83±3.93）, and （140.29±4.18） kj · m-2 · h-1, respectively, and there was no significantly statistical difference found between the determined BMR and the calculated results from Schofield equation （adjusted） classified by sex, all P values〉0.05. Conclusion The BMR of young adults aged 20-29 years old in Changsha was in the national average level, and the adjusted Schofield equation displayed fine accuracy in predicting BMR of young adults aged 20-29 years old in Changsha.
