To investigate anemia rate and to analyze related factors in maternal women in Taicang of Jiangsu province. 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. Age of the 11 930 pregnant women was (27.0±4.5) years old, and the (50) ((25)-(75)) of BMI at the first trimester was 21.4 (19.6-23.7) kg/m(2). 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 ( (95): 1.28 (1.07-1.53)), body mass index(BMI) <18.5 kg/m(2) at the first trimester ( (95): 1.14 (1.00-1.29)), non-local residence ( (95): 1.35 (1.20-1.52)), education of middle school and lower ( (95): middle school: 1.24 (1.05-1.47), primary school: 1.36 (1.01-1.82)), occupation of housewife or farmer ( (95): housewife: 1.21 (1.06-1.38), farmer: 1.21 (1.03-1.44)). Anemia at 42 days postpartum was associated with multipara ((95): 1.59 (1.12-2.27)), anemia at the first trimester ((95): 3.26 (1.92-5.55)), no folic acid supplementation at the first trimester ((95): 1.34 (1.00-1.80)), and hemorrhage≥500 ml during 24 h postpartum ((95): 2.26 (1.02-4.97)). 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.
调查江苏省太仓市孕产妇贫血率并分析相关因素。2014 - 2016年期间，江苏省太仓市有13278名孕妇在25家医院进行产前检查并分娩。我们排除了1179名妊娠12周后登记的孕妇、144名孕期未检测血红蛋白的孕妇以及25名孕周记录错误的孕妇。最终，对11930名孕妇的数据进行了分析。从妇幼保健电子病历系统中，我们获取了这些孕妇的基本信息、血红蛋白水平以及孕期和产后的相关数据。描述了贫血率，并使用多因素非条件logistic回归分析确定了与贫血相关的因素。11930名孕妇的年龄为(27.0±4.5)岁，孕早期BMI的中位数((25) - (75))为21.4(19.6 - 23.7)kg/m²。孕期贫血率为37.2%(4434/11930)。孕早期、孕中期和孕晚期的贫血率分别为5.5%(276/5035)、24.4%(1802/7377)和47.8%(3328/6966)。产后42天贫血率为19.9%(680/3418)。多因素非条件logistic回归显示，孕期贫血与产前登记时孕妇年龄<21岁((95%CI):1.28(1.07 - 1.53))、孕早期体重指数(BMI)<18.5kg/m²((95%CI):1.14(1.00 - 1.29))、非本地户籍((95%CI):1.35(1.20 - 1.52))、初中及以下文化程度((95%CI):初中:1.24(1.05 - 1.47)，小学:1.36(1.01 - 1.82))、家庭主妇或农民职业((95%CI):家庭主妇:1.21(1.06 - 1.38)，农民:1.21(1.03 - 1.44))有关。产后42天贫血与多胎妊娠((95%CI):1.59(1.12 - 2.27))、孕早期贫血((95%CI):3.26(1.92 - 5.
