摘　　要：目的通过分析2010-2012年中国居民营养与健康状况监测中农村老年人群血清25-羟基维生素D[25(OH)D]水平,评价我国农村老年人维生素D(VD)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,调查对象包含中国大陆31个省(直辖市、自治区)的45个普通农村和29个贫困农村中60岁以上老年人,共2754名,放射免疫试剂盒测定25(OH)D,采用中国老年学会骨质疏松委员会制定的VD与成年人骨骼健康应用指南(2014年)标准进行老年人VD营养状况的判定。结果中国农村老年人群血清25(OH)D P_(50)(P_(25)~P75)为23.42(16.88~30.65)ng/ml;普通农村老年人群25(OH)D的水平高于贫困农村,分别为24.16(17.04~31.34)和22.44(16.66~29.84)ng/ml(P=0.0048);男性高于女性,分别为25.08(18.32~32.70)和22.21(15.92~28.55)ng/ml(P<0.0001);居住在南方的老人血清25(OH)D水平高于居住在北方的老人,分别为24.48(18.05~31.00)和21.97(15.90~30.05)ng/ml(P<0.0001)。中国农村老年人VD充足率为63.80%,缺乏率为9.88%,不足率26.33%。普通农村老人VD不足率低于贫困农村,差异有统计学意义(P<0.001)。男性老人VD缺乏、不足率均低于女性,差异有统计学意义(P<0.05)。南方老人VD不足率均低于北方老人,差异有统计学意义(均P<0.0001)。不同年龄、民族、家庭年人均收入的农村老人VD缺乏、不足率差异均无统计学意义(均P>0.05)结论中国农村老年人群存在VD缺乏和不足现象,居住在北方,贫困农村,女性老人发生VD缺乏的风险更高,应采取积极的干预措施。Objective To evaluate the vitamin D status of elderly people residing in rural areas of China by analysing serum 25-hydroxyvitamin D（25（OH）D） levels from the 2010-2012 China National Nutrition and Health Survey（CNNHS）. Methods Multistage stratified cluster sampling method and questionnaire were used in the CNNHS 2010-2012. This survey included 2754 people aged over 60 years old from 45 general rural areas and 29 poor rural areas from 31 provinces of China. The serum 25（OH）D was determined by radioimmunoassay（Diasorin U.S.A）. The vitamin D deficiency was judged by the application guideline for vitamin D and bone health in adult Chinese（2014 Starter Edition）. Results The P（50） of serum 25（OH）D concentration of Chinese rural elderly residents was 23.42（P（25）-P（75）,16.88-30.65） ng/ml. Compared with the 25 OHD level of poor rural elderly（22.44, 16.66-29.84 ng/ml）, the level of general rural elderly was 24.16（17.04-31.34） ng/ml, which was significant higher（P=0.0048）. While the serum 25 OHD concentration of the elderly men（25.08,18.32-32.70ng/ml） was significantly higher than that of the women（22.21,15.92-28.55ng/ml）（P〈0.0001）. The serum 25（OH）D concentration of residents living in south China was 24.48（18.05-31.00）ng/ml, which was also significantly higher than that in north China（21.97, 15.90-30.05ng/ml）（P〈0.0001）. In the Chinese rural elderly residents, the prevalence of vitamin D deficiency, inadequacy and normal status were 9.88%, 26.33%, and 63.73%, respectively. The prevalence of vitamin D inadequacy in poor rural areas was significantly higher than that in general rural areas（P〈0.001）. The prevalence of vitamin D deficiency and inadequacy in females were significantly higher than those in males（P〈0.05）. The prevalences of vitamin D deficiency and inadequacy in north China were also significantly higher than those in south China（P〈0.0001）. However, the prevalence of vitamin D deficiency and inadequacy by age
