Abstract

Abstract

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.
