To study the status and influential factors of iron deficient anemia (IDA) among infants aged 8 months in Changsha City. Methods: A case-control study was performed in this research. The case group including 105 8-month-old infants definitely diagnosed as IDA based on standardized blood test. Four-times numbers of age- and genger-matched infants without IDA were selected as a control group. Chi-square test and conditional logistic regression was used to analyze the influential factors for IDA. Results: The incidence rate of IDA among infants aged 8 months in Changsha City was 14.7%. The risk factors were as follows: mother with anemia in late pregnancy (OR=3.540, 95% CI 1.898 to 6.601), mixed feeding within 6 months old (OR=1.682, 95% CI 1.099 to 2.574), artificial feeding within 6 months old (OR=4.162, 95% CI 1.343 to 12.896), complementary feeding before 6 months old (OR=1.423, 95% CI 1.022 to 1.982), complementary feeding at or after 7 months old (OR=4.415, 95% CI 2.150 to 9.064), recurrent respiratory tract infections within 8 months old (OR=2.878, 95% CI 1.224 to 6.764), and repeated diarrhea within 8 months old (OR=3.710, 95% CI 1.533 to 8.980). Conclusion: There is certain incidence rate of IDA among infants aged 8 months in Changsha City. To prevent the IDA among infants, we should treat mothers' anemia during pregnancy, advocate scientific feeding, encourage complete breastfeeding until 6 months old, add complementary food timely and reasonably, treat infants suffering from respiratory or digestive diseases actively.
研究长沙市8月龄婴儿缺铁性贫血（IDA）的患病状况及影响因素。方法：本研究采用病例对照研究。病例组为105名经标准化血液检测确诊为IDA的8月龄婴儿。选取4倍数量的年龄和性别匹配的无IDA婴儿作为对照组。采用卡方检验和条件logistic回归分析IDA的影响因素。结果：长沙市8月龄婴儿IDA发病率为14.7%。危险因素如下：母亲孕晚期贫血（OR=3.540，95%CI 1.898至6.601）、6月龄内混合喂养（OR=1.682，95%CI 1.099至2.574）、6月龄内人工喂养（OR=4.162，95%CI 1.343至12.896）、6月龄前添加辅食（OR=1.423，95%CI 1.022至1.982）、7月龄及以后添加辅食（OR=4.415，95%CI 2.150至9.064）、8月龄内反复呼吸道感染（OR=2.878，95%CI 1.224至6.764）、8月龄内反复腹泻（OR=3.710，95%CI 1.533至8.980）。结论：长沙市8月龄婴儿IDA有一定发病率。为预防婴儿IDA，应在孕期治疗母亲贫血，提倡科学喂养，鼓励纯母乳喂养至6月龄，及时合理添加辅食，积极治疗患有呼吸道或消化道疾病的婴儿。
