摘　　要：目的 探究广州市孕中期妇女营养素补充剂使用率及使用量情况并进行评估。方法 2017年3月―2018年11月在广州市某医院纳入常规产检的孕20~28周孕妇,采用经信效度检验的问卷面对面收集孕妇过去1个月的营养素补充剂及食物摄入情况,根据相应成分表分别计算各营养素摄入量,其中营养素总摄入量等于补充剂来源摄入量加食物来源摄入量。结果 1 035名孕妇中,孕中期营养素补充剂使用率为80.2%;大部分孕妇使用复合类补充剂;各营养素中钙(76.2%)和叶酸(51.6%)补充率最高。除铜外,其余营养素食物摄入量均存在一定比例的孕妇未达到平均需要量(estimated average requirement, EAR)、推荐摄入量(recommended nutrient intake, RNI)或适宜摄入量(adequate intake, AI),特别是维生素B6、叶酸和钙;进一步纳入营养素补充剂摄入量分析发现使用组营养素总摄入量达到EAR、RNI/AI的比例均有所提高,且使用组总摄入情况优于未使用组(如使用组孕妇钙总摄入量达到RNI的比例为61.4%,而未使用组仅为8.8%)。结论 广州市孕中期妇女营养素补充剂使用率整体处于较高水平,孕中期孕妇仅靠食物难以完全满足营养素需求,合理使用营养素补充剂可改善营养素摄入情况。Objective To estimate the use of nutrient supplements among women in the second trimester of pregnancy in Guangzhou City. Methods A total of 1 035 pregnant women(20-28 weeks’ gestation) were recruited in a hospital in Guangzhou from March 2017 to November 2018. A validated food frequency questionnaire was used to assess nutrient supplement and food intakes in the past month, based on which the daily nutrient intake was calculated. We also calculated the total nutrient intake by summing up the nutrient intake from supplements and food. Results Among all the pregnant women, 80.2% used nutrient supplements during the second trimester, and most of them used compound supplements. Among various nutrients, the utilization rates of calcium(76.2%) and folic acid(51.6%) were highest. There were a certain proportion of pregnant women whose nutrient intake from food(except copper) did not reach the estimated average requirement(EAR) and recommended intake(RNI)/adequate intake(AI), especially for vitamin B6, folic acid, and calcium. When nutrient intake from supplement was included, we found that the proportion of total nutrient intake reaching EAR and RNI/AI increased in pregnant women who used supplements, which was significantly higher than that in those who did not(For example, the proportion of total calcium intake reaching RNI was 61.4% in pregnant women who used supplements, but only 8.8% in those who did not). Conclusions The utilization rate of nutrient supplements among pregnant women in the second trimester in Guangzhou is relatively high. Nutrient intake from food can’t fully meet the needs of most pregnant women. Nutrient supplements should be used appropriately to improve their nutritional status.
