【摘要】：目的:探讨长沙市8月龄婴儿缺铁性贫血状况及其影响因素。方法:采用病例对照研究,将8月龄规范化血常规检测明确诊断为缺铁性贫血的105例婴儿纳入病例组,按1:4个体匹配,发生1个新病例的同时选取4例同一街道、同一性别按相同标准诊断未发生缺铁性贫血的婴儿作入对照组,收集相关资料,运用χ2检验、条件logistic回归分析婴儿缺铁性贫血发生的影响因素。结果:长沙市8月龄婴儿缺铁性贫血发生率为14.7%。8月龄婴儿发生缺铁性贫血的危险因素包括:母亲孕晚期贫血(OR=3.540,95%CI:1.898~6.601)、6月龄内混合喂养(OR=1.682,95%CI:1.099~2.574)、6月龄内人工喂养(OR=4.162,95%CI:1.343~12.896)、6月龄前添加辅食(OR=1.423,95%CI:1.022~1.982)、7月龄及以后添加辅食(OR=4.415,95%CI:2.150~9.064)、8月龄内反复呼吸道感染(OR=2.878,95%CI:1.224~6.764)、8月龄内反复腹泻(OR=3.710,95%CI:1.533~8.980)。结论:长沙市8月龄婴儿缺铁性贫血仍有一定的发生率,应改善母亲孕期贫血,提倡科学喂养,鼓励纯母乳喂养至6月龄,并及时合理添加辅食,积极治疗罹患呼吸系统和消化系统疾病的患儿,预防婴儿缺铁性贫血的发生。
[Abstract]:Objective: to investigate the status and influencing factors of iron deficiency anemia in 8-month-old infants in Changsha. Methods: 105 infants with iron deficiency anemia diagnosed by standardized blood routine test at the age of 8 months were included in the case group by case-control study. According to 1:4 individual matching, 4 cases of the same street were selected at the same time. Infants diagnosed without iron deficiency anemia according to the same sex were enrolled into the control group. The relevant data were collected and the influencing factors of iron deficiency anemia were analyzed by 蠂 2 test and conditional logistic regression. Results: the incidence of iron deficiency anemia in 8-month-old infants in Changsha was 14.7%. The risk factors of iron deficiency anemia in 8-month-old infants included maternal anemia in the third trimester of pregnancy (OR=3.540,95%CI:1.898~6.601). Mixed feeding within 6 months of age (OR=1.682,95%CI:1.099~2.574), artificial feeding within 6 months of age (OR=4.162,95%CI:1.343~12.896), supplementary feeding (OR=1.423,95%CI:1.022~1.982) before 6 months of age, Supplementary food (OR=4.415,95%CI:2.150~9.064), recurrent respiratory tract infection (OR=2.878,95%CI:1.224~6.764) and recurrent diarrhea (OR=3.710,95%CI:1.533~8.980) were added at and after 7 months of age. Conclusion: there is still a certain incidence of iron deficiency anemia in 8-month-old infants in Changsha City. Anemia during pregnancy should be improved, scientific feeding should be advocated, exclusive breastfeeding should be encouraged to the age of 6 months, and supplementary food should be added in a timely and reasonable manner. Actively treat children with respiratory and digestive diseases to prevent iron deficiency anemia in infants.
