2010—2012年湖北省不同性别成年居民膳食蛋白质摄入与代谢综合征相关性

Correlation between dietary protein intake and metabolic syndrome in Hubei Province adult residents in 2010-2012

目的探讨湖北省不同性别居民膳食蛋白质摄入与代谢综合征(MS)的相关性。方法数据来自2010—2012年中国居民营养与健康状况监测,采用多阶段分层与人口成比例的整群随机抽样方法,抽取湖北省6个监测点1827名≥18岁成年人,其中男性779名,女性1048名。采用连续3天24小时个人回顾法进行膳食调查;对调查对象进行体检和血糖、血脂检测。采用Logistic回归方法分析不同性别居民膳食蛋白质摄入与MS的危险度(OR)、95%CI。结果调整研究人群基本特征和总能量等混杂因素干扰后,蛋白质供能比例和动物性食物提供蛋白质比例在男性组为MS的危险因素(OR=1.44、1.19和2.03,OR=1.16、2.02和2.08),在女性组与MS无显著性相关(趋势检验P>0.05)。结论膳食蛋白质摄入与MS的相关性存在性别差异。蛋白质供能比例和动物性食物提供蛋白质比例可能为男性MS发生的危险因素。

Objective To explore the correlation between dietary protein intake and metabolic syndrome（MS） among the men and women of Hubei Province. Methods Data were obtained from the 2010 - 2012 Chinese National Nutrition and Health Survey in Hubei Province. Cross-sectional data on 1827 men and women aged 18 years and above was gathered from 6 monitoring sites by multi-stage stratified and Probability Proportionate to Size（PPS） cluster randmn sampling method . All subjects took the dietary survey with the 24-hour recall method for 3 consecutive days, medical examination and blood assay. Prevalence of MS was defined under the diagnostic criteria of Joint Interim Statement （JIS2009）, and the logistic regression was used to explore the possible relationships between dietary protein intake and MS among 18 years old and above adults, when calculating the OR and its 95% CI of MS. Results After adjusting for covariates, increased risks of MS were related with percentage of energy from protein （ OR = 1.44, 95% CI 1.19 -2.03 ） and percentage of protein from animal foods（ OR = 1.16, 95% CI 2.02- 2.08） among men. Meanwhile, no significant correlations were shown between dietary protein intake and MS among women. Conclusion There are gender differences at the correlation between dietary protein intake and MS. Percentage of energy from protein and percentage of protein from animal foods could possibly be the risk factors of MS among men.
