摘　　要：目的分析2010—2012年中国农村老年人群血清视黄醇水平,评价中国农村老年人维生素A的营养状况。方法 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样,调查对象为中国内地31个省(直辖市、自治区)的45个普通农村和30个贫困农村中60岁及以上老年人,共2413名。采用问卷调查收集调查对象基本情况,高效液相色谱法测定血清视黄醇水平。按照WHO推荐标准进行老年人血清视黄醇营养状况的判定,比较不同特征老年人血清视黄醇水平,及其维生素A缺乏率、边缘缺乏率差异。结果中国农村老年人群总体血清视黄醇的P50(P25~P75)为1.88(1.45~2.45)μmol/L;其中普通农村老年人群血清视黄醇水平低于贫困农村,分别为1.86(1.44~2.41)μmol/L和1.92(1.46~2.48)μmol/L(χ~2=5.1428,P=0.0233);男性高于女性,分别为1.97(1.48~2.54)μmol/L和1.82(1.42~2.33)μmol/L(χ~2=22.3383,P<0.0001)。农村老年人维生素A缺乏、边缘缺乏率分别为2.28%、6.30%;其中普通农村老年人维生素A缺乏率、边缘缺乏率分别为2.79%和6.84%,均高于贫困农村(分别为1.53%和5.51%),地区间差异无统计学意义。男性老年人维生素A缺乏率和边缘缺乏率分别为2.18%和5.37%,女性老年人维生素A缺乏率和边缘缺乏率分别为2.38%和7.21%,性别间差异无统计学意义。60~69岁老年人维生素A缺乏率和边缘缺乏率分别为1.93%和5.87%,70~79岁老人缺乏率和边缘缺乏率分别为3.17%和6.20%,≥80岁缺乏率和边缘缺乏率分别为1.47%和11.74%。3个年龄段老年人的维生素A缺乏率差异无统计学意义,边缘缺乏率差异有统计学意义(χ~2=7.3858,P=0.039)。结论中国农村老年人群存在维生素A缺乏,其中80岁以上老年人边缘性缺乏较高。Objective To assess population by analyzing the serum retinol the vitamin A status of Chinese rural levels of Chinese rural elderly residents elderly in 2010 -2012. Methods Data were from the Chinese National Nutrition and Health Survey in 2010 -2012. Using the multistage stratified cluster sampling method, serum samples from the elderly residents aged above 60 years old （including） , were obtained from 45 general rural and 30 poor rural. The basic situation of the survey object was collected by the questionnaire survey. The concentration of serum retinol was determined by high performance liquid chromatography （HPLC）. The vitamin A deficiency （VAD） was judged by the related standard recommended by WHO. A total of 2 413 elderly residents were included in the study. The levels of serum retinol and the prevalence of vitamin A deficiency and marginal vitamin A deficiency were also compared. Results The level of serum retinol for rural elderly residents was 1.88 （ 1.45 - 2.45） μmol/L. The serum retinol level of poor rural resident was （ 1.92 （ 1.46 - 2.48 ） μmol/L） , which was significant for the ordinary rural residents （ 1.86（ 1.44 - 2.41 ） μmol/L） （χ^2 = 5. 1428, P = 0. 0233）. The serum retinol of male elderly （ 1.97 （ 1.48 - 2.54） ） was statistically higher than female（ 1.82 （ 1.42 - 2.33 ） ） （χ^2= 22. 3383, P 〈 0. 0001 ）. The prevalence of VAD among Chinese rural elderly residents was 2.28% , 2.79% for ordinary rural residents and 1.53% for poor rural residents. The marginal VAD rate of Chinese rural elderly residents was 6. 30% , 6.84% for ordinary rural residents and 5.51% for poor rural residents. The prevalence of VAD and marginal VAD for male was 2.18% and 5.57% , respectively. The prevalence of VAD and marginal VAD for female was 2.38% and 7.21%, respectively. No statistically difference was observed between different genders. The prevalence of VAD was 1.93%, 3.17% and 1.47% for different age groups （60 - 69, 70 -79 and above 80 years old�
