芜湖市城区2~6岁幼儿园儿童2006-2015年血红蛋白水平及贫血状况分析

目的 了解芜湖市城区2~6岁幼儿园儿童血红蛋白水平及贫血状况，为防治儿童贫血提供科学依据。方法 于2006-2015年采用随机整群抽样，选取城区6~8所幼儿园适龄儿童为调查对象，测定其身高、体重、血红蛋白等。结果 分析6 468人，贫血患病率为5.9%，其中男、女性为6.0%、5.9%;2006、2010、2015年患病率分别为5.5%、7.5%、4.4%，差异有统计学意义(P<0.01);不同年龄段儿童贫血患病率为3.7%~29.5%，随年龄增加有降低趋势(P<0.05);贫血儿童与正常儿童在体重、身高、体质指数、发育迟缓率、肥胖率方面差异均有统计学意义(P均<0.05)。结论 儿童贫血近年来有所改善，但仍不容乐观，低龄儿童需重视贫血防治，贫血影响生长发育，应采取综合措施防治儿童贫血。
