Abstract:
Objective:To investigate anemia rate and to analyze related factors in maternal women in Taicang of Jiangsu province.
Methods:There were 13 278 pregnant women who had prenatal care and gave birth in 25 hospitals during 2014-2016 in Taicang of Jiangsu Province. We excluded 1 179 women who registered after 12 weeks of gestation, 144 women who did not test hemoglobin during gestation, and 25 women whose gestational weeks were incorrect. Finally, data from 11 930 pregnant women were analyzed. From the electronical medical record system of maternal and child health care, we obtained basic information of these pregnant women, their hemoglobin levels and related data during gestation and postpartum. Anemia rate was descripted, and factors associated with anemia were identified using multiple unconditional logistic regression.
Results:Age of the 11 930 pregnant women was (27.0±4.5) years old, and the P50 (P25-P75) of BMI at the first trimester was 21.4 (19.6-23.7) kg/m2. The anemia rate during gestation was 37.2% (4 434/11 930). The anemia rate was 5.5% (276/5 035), 24.4% (1 802/7 377), and 47.8% (3 328/6 966) at the first, second and third trimesters, respectively. Anemia rate at 42 days postpartum was 19.9% (680/3 418). Multiple unconditional logistic regression indicated that anemia during gestation was related with maternal age <21 years old at prenatal registration (OR (95%CI): 1.28 (1.07-1.53)), body mass index(BMI) <18.5 kg/m2 at the first trimester (OR (95%CI): 1.14 (1.00-1.29)), non-local residence (OR (95%CI): 1.35 (1.20-1.52)), education of middle school and lower (OR (95%CI): middle school: 1.24 (1.05-1.47), primary school: 1.36 (1.01-1.82)), occupation of housewife or farmer (OR (95%CI): housewife: 1.21 (1.06-1.38), farmer: 1.21 (1.03-1.44)). Anemia at 42 days postpartum was associated with multipara (OR(95%CI): 1.59 (1.12-2.27)), anemia at the first trimester (OR(95%CI): 3.26 (1.92-5.55)), no folic acid supplementation at the first trimester (OR(95%CI): 1.34 (1.00-1.80)), and hemorrhage≥500 ml during 24 h postpartum (OR(95%CI): 2.26 (1.02-4.97)).
Conclusion:Anemia rate was low for maternal women in Taicang of Jiangsu Province. The factors associated with gestational anemia included pregnant women's age, BMI, local or non-local residence, occupation, and education. The factors associated with postpartum anemia included multipara, anemia at the first trimester, no folic acid supplementation at the first trimester, and hemorrhage 24 h postpartum.
