Abstract:
Objective To explore the related factors of anemia during pregnancy and provide scientific evidence for the primary prevention of anemia during pregnancy.Methods The pregnant women (≤ 12 pregnant weeks) who received the first pregnancy care in a local medical institution in Hunan province from June 2013 to November 2014 were included in this cohort study,and for them anemia had been excluded by physical examination.Baseline survey and follow up till childbirth were conducted for them.A queue-based nested case-control study (1 ∶ 2) was conducted (380 pregnant women with anemia detected in this study as case group,760 pregnant women without anemia randomly selected and matched by age,habitual residence during pregnancy as control group.And t test,x2 test and logistic regression analysis were conducted to identify related factors of anemia during pregnancy.Results Multivariate logistic regression analysis indicated that low family annual income level (net income) (OR=2.08,95％CI:1.22-3.59),low educational level (OR=2.09,95％CI:1.22-3.59),pre-pregnancy perm/hair dye (OR=2.23,95％ CI:1.63-3.05),early pregnancy vomiting (OR=2.51,95％ CI:1.56-4.03) were the risk factors for anemia during pregnancy.Intake of vitamin and trace element supplements (OR=0.69,95％ CI:0.50-0.94),frequent meat,fish,shrimp,egg intakes (OR=0.68,95％CI:0.49-0.92),frequent soy milk,milk intakes (OR=0.51,95％CI:0.27-0.95) were the protective factors for anemia during pregnancy.Conclusion A number of factors,such as family annual income level,education level,poisonous and harmful material contact,pregnancy reaction,nutrition,are related to the incidence of anemia during pregnancy,it is necessary to take preventive measures to reduce the incidence of anemia during pregnancy.
