【摘要】：目的:了解南京市40~60岁成年人不同活动状态下能量消耗的相关因素。方法:招募南京市40~60岁男女性成年人110名,测量其身高、体重,并计算体重指数(body mass index,BMI)与体表面积(body surface area,BSA),通过双能X线体成分扫描仪获得体成分信息。观察其在能量代谢舱内生活11 h期间,处于平躺、运动、上网、睡眠、静息代谢状态的能量消耗。分析年龄、性别、体重、身高、BMI、体成分等指标对不同活动状态能耗的影响。结果:(1)男性受试者基础代谢为(2 036.25±226.45)kcal/d,女性受试者基础代谢为(1 673.21±173.37)kcal/d,差异有统计学意义(P0.01);不同年龄段受试者基础代谢相近,差异没有统计学意义(P0.05)。去除去脂体重(fat-free mass,FFM)的影响后发现,不同活动状态下女性的能耗高于男性且有统计学意义(P0.01);但不同年龄段受试者能耗差异没有统计学意义(P0.05)。(2)男女受试者不同活动状态的能耗与FFM、体重、BSA、BMI和体脂含量等指标存在显著相关(P0.01)。对各相关因素进行多元回归分析后发现,性别、FFM、体脂含量对能耗的影响有统计学意义(P0.05)。结论:南京市40~60岁成年人不同活动状态下的能量消耗主要受到FFM和体脂含量的影响。
[Abstract]:Objective: to investigate the related factors of energy expenditure in 40 ~ 60 years old adults in Nanjing. Methods: 110 male and female adults aged 40 ~ 60 years were recruited and their height and weight were measured. Body mass index (BMI) and body surface area (BMI) were calculated. Body composition information was obtained by dual-energy X-ray body composition scanner. During 11 hours of living in the energy metabolism chamber, they were lying flat, exercising, surfing the net and sleeping. Energy consumption in resting metabolic states. Analysis of age, sex, body weight, Results: the basal metabolism of male subjects was 2 036.25 卤226.45 kcal / d, and that of female subjects was 1 673.21 卤173.37 kcal / d, the difference was statistically significant (P0.01). The difference was not statistically significant (P 0.05). After removing the effect of fat-free FFM, it was found, The energy consumption of female was higher than that of male in different activity state, but there was no significant difference in energy consumption between male and female subjects in different age group (P0.05. 2) the energy consumption and FFM, body weight, BMI and body fat content of male and female subjects in different activity states were not statistically significant. There was a significant correlation between the indexes (P 0.01). The multivariate regression analysis showed that, The effect of body fat content on energy consumption was statistically significant (P 0.05). Conclusion: the energy consumption of 40 ~ 60 year old adults in Nanjing is mainly affected by FFM and body fat content.
