Abstract
ObjectiveTo investigate the prevalence of anemia and related risk factors for pregnant women in China.
MethodBased on Chinese National Nutrition and Health Surveillance 2010-2012, a total of 3 501 pregnant women were investigated from 150 counties of 31 provinces, municipalities and autonomous regions in China, using a multi-stage stratified cluster randomization sampling method. General information of pregnant women, health status, and food intake during the gestation, was collected through a questionnaire investigation. 6 ml fasting venous blood was collected for the determination of hemoglobin concentration. Data were analyzed using multiple logistic regression to investigate the prevalence of anemia and the related influencing factors.
ResultsThe 605 of 3 501 pregnant women had anemia. The prevalence of anemia was 17.2%; and mild anemia accounted for about 61.0% (369/605). Compared with the pregnant women living in the large cities, the OR (95%CI) of those living in the poor rural areas was 1.46 (1.08-1.98). Compared with the pregnant women living in the south area of China, the OR (95%CI) of those living in the north area of China was 1.39 (1.15-1.68); Compared with the pregnant women in the first trimester, the OR (95%CI) of those in the second trimester and the third trimester were 1.79 (1.33-2.43) and 2.11 (1.56-2.85), respectively. The OR (95%CI) of pregnant women who had used folic acid supplementation within the 6 months prior to gestation was 0.76 (0.63-0.93) compared with those who had not used.
ConclusionFrom 2010 to 2012, the epidemic characteristics of anemia was mild for the pregnant women in China, and pregnant women residential areas, periods of pregnancy and whether to take folic acid were related to anemia.
