Female resting energy expenditure and obesity-related indicators / 中国组织工程研究

ABSTRACT

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 kilogrem 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 cdtada 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) k J/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 end 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.
