Prevalence and associated factors of anemia in children aged from 6 months to 5 years old in monitoring points of Guizhou province

Abstract

Objective To understand the prevalence of anemia among children aged 6 months to 5 years old in Guizhou Province, providing a scientific basis for anemia intervention.

Methods A total of 853 children aged 6 months to 5 years old and their families were chosen through a multi-stage stratified cluster sampling method. All the participants were surveyed with relevant questionnaires and hemoglobin testing. Unconditional logistic regression analysis was used to explore the associated factors.

Results The anemia rate among 853 children aged 6 months to 5 years old in Guizhou was 14.9%, among which mild, moderate and severe anemia accounted for 70.08%, 29.13% and 0.79%, respectively, and the detection rate of anemia decreased with the growth of age ( χ ² = 27.87, P <0.01). Logistic regression analysis showed that anemia was negatively correlated with regular growth monitoring. Children with complementary food supplements after 6 months old were less likely to develop anemia than children with complementary food supplements younger than 4 months; Compared with 6-12-month-old group, older children were less likely to develop anemia; Delayed weaning increased the risk for childhood anemia.

Conclusion The prevalence of anemia among children aged 6 months to 5 years old in monitoring area of Guizhou province is still alerting. Introducing scientific feeding practice to parents, regular growth monitoring, deep cooperation among the government, medical institutions and the family, are vital parts in effectively reducing childhood anemia.

【摘要】 目的 了解贵州省监测点6月~5岁儿童贫血状况及其影响因素，为儿童贫血改善提供科学依据。 方法 采用多阶段分层整群抽样方法对贵州省监测点853名6月 ~5岁儿童进行实验室检测血红蛋白含量，对家属进行相关问卷 调査; 采用非条件Logistic回归分析探讨儿童贫血的影响因素。 结果 6月~5岁儿童贫血率为14.9%，其中轻度、中度、重 度贫血分别占70.08%，29.13%及0.79%，且贫血率有随年龄增加而降低的趋势 ( χ = 27.87， P<0.01)。Logistic回归分析显 示，儿童贫血发生率与其是否定期监测儿童生长发育和辅食添加月龄大于6月呈负相关（ OR值分别为0.34，0.19);相较于 6~<12月龄组，其他髙月龄组儿童更不易发生儿童贫血（ OR值分别为0.23，0.09，0.07，0.07); 儿童断奶月龄与发生儿童贫 血正相关（ OR = 1.27)。 结论 贵州省监测点6月~5岁儿童贫血率偏髙。应教育家长科学喂养，注意儿童体检，促进政府、 医疗机构和家庭的合作，以达到有效降低儿童贫血率的目标。
