不同能量代谢水平对西安市中老年女性体质健康的影响

Level of different energy metabolism on constitution of women in Xi'an City

目的探讨西安市中老年女性不同剩余能量水平与体质健康的关系。方法2011年采用多阶段分层随机抽样的方法,抽取西安市40-60岁650名长住居民进行形态、机能、血生化、心理等指标进行测量;通过问卷调查其营养及体力活动状况,采用四分位数法对剩余能量（SE）进行水平分级,

Objective To analyze the relationship between different level of surplus energy and constitution health among middle-aged and elder females. Methods Multistage stratified random sampling method was used and 650 residents aged 40- 60 years in Xi＇an City were selected for measurement of body shape,function,blood biochemistry and psychology indicators and questionnaire survey of nutritional and physical activity status. The subjects were divided into the following four groups according to surplus energy（ SE） classification by using of quartile method,When SE 〈P25 for the low surplus energy group,P25≤SE P50 for the moderate surplus energy group,P50≤ SE P75 for the high surplus energy group,P75 〈SE for higher surplus energy group. Results Body mass,waist circumference, hip circumference, arm skinfold thickness, abdominal skinfold thickness,leg skinfold thickness,body mass index,waist-hip ratio and body fat rateamong surplus energy groups was statistically significant（ P〈 0. 05 or P 〈0. 01）.Cardiopulmonary function and mental health level of the high energy group and the moderate surplus energy group were better than the low surplus energy group and higher surplus energy group,it was statistically significant（ P 〈0. 05）,and the level of glucose,TG,TC,LDL declined significantly and the level of HDL increased remarkably（ P 〈0. 05）. Conclusion The energy intake of dietary and the energy consumption of physical activity are factors influencing the level of constitution health.
