摘　　要：目的利用2015年中国成人慢性病与营养监测数据,分析中国育龄女性锌营养状况及影响因素。方法采用多阶段分层与人口成比例的整群随机抽样方法,在全国31个省(直辖市、自治区)302个监测点中抽取1818名18-49岁育龄女性作为调查对象。通过电子问卷收集调查对象的基本信息,采用电感耦合等离子体质谱仪检测调查对象的血清锌浓度,依据国际锌营养顾问组(International Zinc Nutrition Consultative Group,IZiNCG)推荐的血清锌缺乏标准进行判定,应用多因素Logistic回归模型分析中国育龄女性锌缺乏的影响因素。结果我国育龄女性血清锌浓度中位数为1030.8μg/L,汉族血清锌浓度高于少数民族(P<0.05);血清锌缺乏率为5.03%,农村血清锌缺乏率高于城市(P<0.05),少数民族血清锌缺乏率高于汉族(P<0.05);多因素logistic回归模型显示,相对于城市育龄女性,农村育龄女性血清锌缺乏风险较高,OR值为2.08(P<0.05)。结论中国育龄女性血清锌缺乏率总体较低,在农村育龄女性中该问题更为突出。[营养学报,2020,42(6):531-536]Objective To analyze the zinc nutrition status and its influencing factors in Chinese women of childbearing age using the China Adult Chronic Disease and Nutrition Surveillance(2015)Data.Methods Using the multi-stage(2015)stratified and population proportional cluster random sampling method,1818 women aged 18 to 49 years were selected from 302 monitoring sites in 31 provinces,municipalities or autonomous regions in China.The basic information of the subjects was collected by electronic questionnaires,and their serum zinc concentrations were detected by inductively coupled plasma mass spectrometry(ICP-MS)according to the standard for serum zinc deficiency recommended by the International Zinc Nutrition Consultative Group(IZiNCG).The influencing factors of zinc deficiency in Chinese women of childbearing age were analyzed by the multivariate logistic regression model.Results The median serum zinc concentration of chinese women of childbearing age was 1030.8μg/L.The serum zinc concentration of Han population was higher than that of ethnic minoritie(P<0.05).The rate of serum zinc deficiency was 5.03%,higher in rural areas than in urban areas(P<0.05),and higher among ethnic minorities than among Han populations(P<0.05).The multivariate logistic regression model showed that rural women of childbearing age had higher risk of serum zinc deficiency than urban ones(OR value was 2.08)(P<0.05).Conclusion The overall rate of serum zinc deficiency in Chinese women of childbearing age is relatively low.Rural women should pay more attention to the zinc nutrition.[ACTA NUTRIMENTA SINICA,2020,42(6):531-536]
