摘　　要：目的 分析1989-2011年广西城乡18～65岁城乡居民膳食维生素A摄入状况及变化趋势. 方法 利用1989-2011年“中国健康与营养调查”9轮调查数据,选取广西18～65岁城乡居民作为研究对象.以膳食总维生素A、胡萝卜素和视黄醇每日平均摄入量作为维生素A摄入状况的评价指标,分析1989-2011年广西城乡居民膳食维生素A摄入状况、视黄醇占总维生素A摄入的比例及总维生素A达到推荐摄人量（RNI）比例的人群分布变化趋势. 结果 1989-2011年间,广西城乡居民膳食总维生素A、胡萝卜素、视黄醇摄入呈上升趋势,膳食总维生素A从1989年的789.07μgRE/d上升至2011年的1 306.57 μgRE/d;视黄醇在总维生素A摄人中的比例,2006年以前城乡呈上升趋势,2006年后城乡呈下降趋势,城乡差距逐步缩小;膳食维生素A大于等于90％RNI的人群比例从1989年的40.9％上升到2011年的 70.0％;膳食维生素A达到80％RNI、60％ RNI、小于60％ RNI的人群比例分别从1989年的6.6％、15.1％、30.4％下降到2011年的5.1％、8.3％、15.2％. 结论 23年间,广西城乡居民膳食维生素A、胡萝卜素、视黄醇呈上升趋势,城乡摄入差别在缩小,但农村维生素A摄入不足的人群高于城镇,需根据城乡维生素A摄入的异同点制定相应干预措施.Objective To analyze dietary vitamin A intake and its changing trends among urban and rural residents aged 18-65 years in Guangxi from 1989 to 2011.Methods Urban and rural residents aged 18-65 years in Guangxi were enrolled in the study.The analysis used individual level,consecutive 3 d dietary recall data from 9 rounds of the China Health and Nutrition Surveys in 1989-2011.The average daily dietary intakes of vitamin A,carotene and retinol were selected as the evaluation indexes.The status of dietary vitamin A intake,retinol proportion,ratio of population who had achieved the recommended nutrient intake （RNI） and the changing trends in the residents were analyzed.Results Dietary intakes of total vitamin A,carotene and retinol of the residents in Guangxi showed an increasing tendency from 1989 to 2011.The total dietary vitamin A went up to 1,306.57 μgRE/d in 2011 from 789.07 μgRE/d in 1989.The proportion of retinol intake in total vitamin A had a turning point in 2006.It increased from 1989 to 2006,but decreased after 2006,and the disparities between urban and rural areas were gradually narrowing.The proportion of population with dietary vitamin A intake which was ≥ 90% RNI went up to 70.0% in 2011 from 40.9% in 1989.The proportions of populations with dietary vitamin A intakes up to 80% RNI,60% RNI and below 60% RNI decreased from 6.6%,15.1%,and 30.4% in 1989 to5.1%,8.3%,and 15.2% in2011,respectively.Conclusions The intakes of dietary vitamin A,carotene and retinol show an increasing trend in urban and rural residents in Guangxi in the 23 years between 1989 and 2011.The intake disparities between urban and rural areas are narrowing; however,the prevalence of vitamin A deficiency in rural population is higher than that in urban population.It is necessary to develop target intervention measures based on the situation of vitamin A intake in urban and rural areas.
