女性静息能量消耗与肥胖相关指标相关性的研究

目的：分析女性静息能量消耗与肥胖相关指标的关系，比较肥胖女性与正常体质量女性静息能量消耗、公斤体质量静息能量消耗的差异。 方法：选择2004/2008在北京妇产医院内分泌科就诊或体检的健康女性565例，对其进行身高、体质量测量，使用人体代谢仪测定静息能量消耗，计算体表面积、体质量指数、公斤体质量静息能量消耗，按体质量指数肥胖诊断标准，分为两组：肥胖组女性179例，正常体质量女性240例，对其测量结果进行正态性检验、相关性分析和两独立样本秩和检验或t检验。 结果：565例健康女性静息能量消耗为正态性资料，测量值为(5.793±0.940) kJ/d，静息能量消耗与体质量、身高、体质量指数、体表面积呈正相关关系(P < 0.05)，与年龄无明显相关性(P > 0.05)，肥胖组与正常体质量组年龄、身高之间的差异无显著性意义(P > 0.05)，静息能量消耗、公斤体质量静息能量消耗差异均有显著性意义(P < 0.05)。 结论：女性静息能量消耗与其身高、体质量、体质量指数、体表面积存在正相关关系，以体质量指数诊断的肥胖女性静息能量消耗高于正常体质量女性，公斤体质量静息能量消耗肥胖组小于正常体质量组。

Study on the relationship between female resting energy expenditure and obesity-related indicators

OBJECTIVE: To analyze the relationship between female resting energy expenditure and obesity-related indicators, and to compare the differences of resting energy expenditure and resting energy expenditure per kilogram between obese women and normal weight women. METHODS: A total of 565 healthy women who did medical examination or visited Department of Endocrinology in Beijing Obstetrics and Gynecology Hospital between 2004 and 2008 were recruited, their height and weight were measured. Human metabolic apparatus was used to measure resting energy expenditure, then body surface area, body mass index, resting energy expenditure per kilogram were calculated. According to the diagnostic criteria of obesity by body mass index, the 565 cases were divided into two groups: obese group (n=179) and normal body weight group (n=240), and all the measurement results were calculated and did the tests of normality, correlation analysis and two independent samples rank sum test or t test. RESULTS: The resting energy expenditure of 565 healthy women were normality, the result was (5.793±0.940) kJ/d, and resting energy expenditure showed a positive correlation with body weight, height, body mass index and body surface area (P < 0.05), while showed no significant correlation with age (P > 0.05), there was no significant difference of age and height between obese group and normal body weight group (P > 0.05), while a statistical significant difference was found in resting energy expenditure and resting energy expenditure per kilogram between obese group and normal body weight group (P > 0.05). CONCLUSION: There is a positive correlation that female resting energy expenditure with their height, weight, body mass index and body surface area, and the resting energy expenditure of obese women is higher than that of normal body weight women, while resting energy expenditure per kilogram of obese women is lower than that of normal body weight women.
