【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(P0.0001);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(P0.0001)。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(P0.001)。男性老人VD缺乏、不足率均低于女性,差异有统计学意义(P0.05)。南方老人VD不足率均低于北方老人,差异有统计学意义(均P0.0001)。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P0.05)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。
[Abstract]:Objective to analyze the serum levels of 25-hydroxyvitamin D (25-hydroxyvitamin D) in the rural elderly population in China from 2010 to 2012. Methods from 2010 to 2012, the nutritional status of Chinese residents with vitamin D (VD) was assessed by a cluster random sampling method with multistage stratification and population proportion. The survey included 2754 elderly people aged over 60 in 45 ordinary rural areas and 29 poor rural areas in 31 provinces (municipalities and autonomous regions) in mainland China. The radioimmunoassay kit was used to determine the nutritional status of the elderly in rural China, using the criteria of VD and adult bone health (2014), which were formulated by the Osteoporosis Committee of the Chinese Academy of Geriatrics, to determine the nutritional status of the elderly. The level of serum 25 OHG / D was 23.42 / 16.88 / 30.65 ng / ml / ml, and the level of 25OHH / D in the elderly was higher than that in the poor rural areas. The levels of serum 25OH1D in the elderly living in the south were higher than those in the north, respectively (24.16 / 17.04 / 31.34) and 22.44 / 16.66 / 29.84 ng / ml / ml / ml / ml / ml respectively, respectively, and 25.08 / 18.32 / 32.70 for men and 28.55 ng / ml / ml / ml / ml for those living in the north, respectively, and the levels of serum 25OH1D in the elderly living in the south were significantly higher than those in the northern part of the country. The VD adequacy rate was 63.80%, the deficiency rate was 9.88, and the deficiency rate was 26.33%. The VD deficiency rate of the ordinary rural elderly was lower than that of the poor rural areas (P 0.001), the difference was statistically significant (P 0.001). The VD deficiency rate of the male elderly was lower than that of the female, and the VD deficiency rate of the elderly was lower than that of the female. The difference was statistically significant (P 0.05). The VD deficiency rate of the elderly in the south was lower than that in the north, and the difference was statistically significant (P 0.0001). The VD of the rural elderly with different age, nationality and family per capita income was short of VD. There was no significant difference in deficiency rate (P0.05). Conclusion there is a lack of VD and deficiency among the elderly population in rural China. The risk of VD deficiency among the elderly living in the north and poor rural areas is higher than that among the female elderly. Therefore, active intervention measures should be taken.
