【摘要】 目的探讨1991～2006年湖北省中老年居民膳食结构特点及变化趋势。方法利用"中国居民健康与营养调查"的资料,选取1991、1993、1997、2000、2004和2006年调查中45岁健康中老年居民作为研究对象。以能量、蛋白质、脂肪等营养素的摄入量占推荐摄入量(RNI)的百分比及谷类食物和动物性食物提供的能量和蛋白质在摄入的总能量和蛋白质中所占的比例作为营养素摄入和膳食状况评价的指标。结果 2006年,城区、郊区、县城优质蛋白在总蛋白中所占比例均达到推荐摄入比例,但1991～2006农村居民动物性食物及豆类来源优质蛋白增幅较小,2006年优质蛋白在总蛋白质中比例仅为28.5%,低于推荐摄入比例。城区中老年居民每日脂肪功能比例偏高,其中1993、1997、2000及2006年的比例为31.3%、34.2%、35.5%和36.9%,均高于推荐摄入比例30%的上限;城区、郊区、县城及农村食用油脂消费量四个地区几乎全部超过中国居民膳食指南中平衡膳食宝塔每天最大消费30克的水平。结论 1991～2006年城区、郊区和县城中老年居民动物性食物消费量显著提高,植物性食物的消费量下降,农村居民的膳食构成变化相对平缓,总体膳食质量仍然较差。蛋白质和能量的摄入量基本已经满足需要,农村居民优质蛋白质摄入有待进一步提高。应控制我省城区居民食物中脂肪的摄入量,并有效改善城区、郊区、县城及农村居民食用油脂的过高摄入状况。更多还原

【Abstract】 Objective To investigate the characteristics and the changing trend of Dietary pattern of Hubei residents aged 45 and over during 1991～2006.Methods The study is baesd on date collected in 1991,1993,1997, 2000,2004 and 2006 in China Health and Nutrition Survey.The sample was aged 45 and over old residents.Take the percentage of energy,protein and fat intake in their recommended intake(RNI),and the proportion of energy,protein from cereal and animal food and protein in the total energy and protein intake.as indicators of nutrient intake and dietary changes.Rsults In 2006,the percentage of high-quality protein in total protein was in the framework of recom- mended intake level in urban,suburban and the county.From 1991 to 2006,high-quality protein from beans and animal food of rural residents increase slowly,the proportion of which in total protein was only 28.5%and lower than the recommended intake.Compared with the upper ratio of recommended intake level(30%),the proportion of energy from fat intake of Middle-aged and old residents in urban areas was relatively higher,which in 1993,1997,2000 and 2006 was 31.3%.The amount of edible oils and fats consumption exceeded 30 grams per day level in urban,suburban, county,and rural areas rural,which was recommended by the balanced diet tower of Dietary Guidelines for Chinese residents.Conclution From 1991 to 2006,animal food consumption of urban,suburban and county middle-aged and old residents significantly increased,at the same time,the consumption of plant food declined.Change in diet pattern of rural residents is relatively moderate,the overall food quality is still poor in rural.Protein and energy intake has meet the basic needs in different region.high-quality protein intake of rural residents need to be further improved.City residents should be controlled in fat food intake,and the high intake of edible oils and fats situation should be effectively improved in the urban,suburban,county,and rural residents.更多还原
