【摘要】：目的研究膳食蛋白质摄入量与不同条件分布下体质指数(BMI)及腰围之间的关系。方法收集"中国健康与营养调查(CHNS)"项目2011年十二省成年居民的膳食调查与体格测量数据。按性别分层后,采用分位数回归分析居民膳食蛋白质摄入量与BMI及腰围的关系。结果研究对象为18岁及以上成年人11 800名,其中成年男性5623(47.7%)名,平均年龄为(51.5±15.1)岁,成年女性6177(52.3%)名,平均年龄为(51.9±15.0)岁,男、女性的膳食蛋白质摄入量分别为(1.1±0.4)和(1.0±0.4)g/kg BW。男、女性在腰围、能量、蛋白质摄入量、碳水化合物摄入量、活动水平、教育程度、吸烟、饮酒及工作状态上差异均有统计学意义(P0.05),而在年龄、BMI、脂肪摄入量及城市农村比例上男、女性别差异均无统计学意义。按性别分层调整混杂因素后分位数回归分析结果显示,膳食蛋白质摄入量在不同性别的各百分位数BMI及腰围的条件分布下回归系数均有统计学意义(P0.05),回归系数平行性检验P0.05。结论不同条件分布下,膳食蛋白质摄入量与BMI及腰围存在负向相关,且呈现趋势性,对于高BMI和高腰围人群,蛋白质摄入量的影响程度更大。
[Abstract]:Objective to study the dietary protein intake and different conditions of distribution of body mass index (BMI) and the relationship between the waist. "Methods Chinese health and Nutrition Survey (CHNS) survey and physical measurement data dietary project 2011 Twelve adult residents. When stratified by sex, by analysis of the relationship between dietary protein intake and waist circumference and BMI regression quantile. The object of the study is over 18 years old and 11800 adults, including 5623 adult male (47.7%), mean age (51.5 + 15.1) years old, female 6177 (52.3%), mean age (51.9 + 15) years old, male, female dietary protein intake (1.1 respectively. + 0.4) and (1 + 0.4) g/kg BW. in male, female waist circumference, energy, protein intake, carbohydrate intake, activity level, education level, smoking, drinking and working condition, there were statistically significant differences (P0.05), and in the age , BMI, fat intake and the proportion of city rural male, female. There were no significant differences in gender stratification after adjustment for confounding quantile regression analysis showed that the dietary protein intake in different gender different percentile BMI and waist circumference to next conditional distribution coefficients were statistically significant (P0.05), the regression coefficient in parallel test of P0.05. distribution under the conditions of different conclusions, there are negative correlation between dietary protein intake and BMI and waist circumference, and presents the trend of high BMI and high waist, the crowd, the influence degree of protein intake is greater.
