目的了解中国普通农村老年人低体重率并探讨其影响因素。方法以2010—2012年中国居民营养与健康状况监测普通农村中25 464名年龄在45岁及以上的人群为研究对象来探讨低体重率,对545名低体重者按照1∶2匹配体重正常者来探讨低体重的影响因素。调查内容包括膳食调查、体格检测、身体活动、生活方式及社会经济等因素。结果中国普通农村中老年人低体重率为5.27%,其中男性为5.52%,女性为5.05%。随着年龄的增加中老年人低体重率有增长趋势(P<0.01)。低体重中老年人在能量、总蛋白质、优质蛋白质、脂肪以及水果的摄入量低于体重正常的中老年人(P<0.05),而吸烟和饮酒的比例则高于体重正常者(P<0.05)。多因素条件Logistic回归结果显示,总蛋白质、水果、蔬菜的摄入是中国普通农村中年老年人低体重的保护因素,而不良的生活方式如吸烟是中老年人低体重的危险因素。结论中国普通农村中老年人低体重率处于较高水平,提倡中老年人增加高蛋白质食物、蔬菜和水果的摄入,戒烟限酒,防止低体重的发生。
Abstract：Objective To know the prevalence of low body weight among middleaged and elderly people in general rural areas of China and investigate the influence factors. Methods A total of 25 464 participants who were 45 years old and above from2010-2012 China National Nutrition and Health Surveillance as subjects to investigate the prevalence of low body weight. For 545 low body weight participants,we performed a1∶ 2 case-control study to investigate the influence factors. The content of survey included3-condecutive days-24-hour dietary recall,physical examinations,physical activity and social economic factor. Results The prevalence of low body weight among middle-aged and elderly people was 5. 27%,5. 52% for male and 5. 05% for female. The prevalence of low body weight increased with the age( P < 0. 01). The daily intake of energy,total proteins,high quality proteins,fat and fruits were lower in low body weight than normal body weight among middle-aged and elderly people( P < 0. 01), however, the consumption of smoking and alcohol were higher in low body weight than normal body weight( P < 0. 01). Multivariate conditional Logistic regression analysis showed that the daily intake of total proteins,vegetables and fruits were protective factors and unhealthy lifestyle such as smoking were risk factors among low body weight people. Conclusion The prevalence of low body weight at a higher level among middle-aged and elderly people in general rural areas of China. It is necessary to promote the middle-aged and elderly people to increase the consumption of high-protein foods,vegetables and fruits,quit smoking and control drinking.
