摘要
目的了解中国农村老年人维生素A水平及影响因素。方法采用随机抽样方法选取2015年中国成人慢性病与营养监测生物样本库的农村老年人血清样本,共纳入3134名60岁以上农村老年人作为研究对象。采用问卷调查收集研究对象基本信息,利用高效液相色谱法分析仪测定调查对象血清中维生素A含量,依据WHO推荐的标准判定人群维生素A营养状况,应用多因素Logistic回归模型探讨中国农村老年人维生素A缺乏与影响因素的关联性。结果血清维生素A含量[M(P25,P75)]为1.92(1.50,2.45)μmoL/L。经加权后的维生素A缺乏率为0.99%,边缘缺乏率为4.38%。西部地区维生素A边缘缺乏率显著高于东部和中部地区,80岁及以上人群显著高于其他年龄,消瘦者显著高于其他,已婚者显著低于未婚/离婚/丧偶者。多因素Logistic回归模型分析显示,性别、年龄和体质指数对维生素A营养状况的影响具有统计学意义(P<0.05)。结论 2015年中国农村老年人维生素A营养状况较好,缺乏率较低。
OBJECTIVE To analyze the level of vitamin A and its influencing factors of Chinese rural elderly. METHODS The serum samples of the rural elderly were selected by random sampling method from the biological sample bank of Chinese Adults Nutrition and Chronic Diseases Surveillance in 2015(CANCDS2015). The basic information of the subjects was collected by questionnaire survey. High performance liquid chromatography(HPLC) method was used to determine the vitamin A nutritional status of the population according to the standard recommended by WHO. Multiple logistic regression analysis was explored the relationship between vitamin A status with the potential relevant factors. RESULTS A total of 3134 elderly from Chinese rural were included in this study. The serum vitamin A concentration(M(P25,P75))was 1.92(1.50,2.45)μmoL/L. The prevalence of vitamin A deficiency was 0.99%(95%CI 0.64%-1.34%), and the prevalence of vitamin A marginal deficiency was 4.38%(95%CI 3.65%-5.10%). The prevalence of vitamin A marginal deficiency was significantly higher in elderly lived in western region than that lived in eastern and central regions of China. The serum vitamin A adequacy rate of rural elderly who were 80 years old and above or thin was relatively low(P<0.05). Married elderly had significant lower vitamin A deficiency rate. The result from multivariate logistic regression model analysis showed that gender, age and body mass index had significant effects on vitamin A nutritional status of Chinese urban elderly(P<0.05). CONCLUSION The nutritional status of vitamin A in rural elderly in China was better, and the deficiency rate was lower.
