目的了解广东省惠州市城区6个月~5岁儿童血红蛋白(hemoglobin,Hb)水平及贫血状况,为制定相应预防措施提供依据。方法对13 966例6个月~5岁儿童的Hb值、贫血情况进行分析比较。结果惠州市城区6个月~5岁儿童总的贫血患病率为14.66%(2048/13 966),6个月~组最高,占该组儿童26.89%(1008/3749),各年龄段贫血发生率差异有统计学意义(P<0.01),随年龄增长有下降趋势。6个月~5岁儿童Hb平均含量为(122.49±11.34)g/L,6个月~组Hb水平最低,Hb含量随年龄增长逐渐升高。儿童贫血以轻度为主,占94.43%;同年龄Hb水平及贫血患病率性别差异均无统计学意义(P>0.05)。结论惠州市城区儿童贫血发病率与2012年全国调查的平均水平基本相符;贫血好发年龄为婴儿期,接近全国农村贫血发病率。应重点加强早期儿童喂养、营养及饮食行为问题的指导与监测,继续推进婴儿贫血防治工作。
Objective To understand the levels of hemoglobin (Hb) and anemia in children aged 6 months to 5 years old in Huizhou City, Guangdong Province, and to provide evidence for the development of appropriate preventive measures. Methods Hb values and anemia in 13 966 children aged 6 months to 5 years were analyzed and compared. Results The prevalence of total anemia in children aged 6 months to 5 years in Huizhou city was 14.66% (2048/13 966), the highest in 6 months ~ 26.89% (1008/3749) of children in this group, with anemia in all age groups The difference was statistically significant (P <0.01), with the increase of age there is a downward trend. The average level of Hb in children from 6 months to 5 years old was (122.49 ± 11.34) g / L, the level of Hb was the lowest in 6 months and increased gradually with the increase of age. Children with mild anemia, accounting for 94.43%; the same age Hb level and the prevalence of anemia gender differences were not statistically significant (P> 0.05). Conclusion The incidence of anemia in urban areas of Huizhou City basically matches the average of the national survey in 2012. The age of onset of anemia is infancy, which is close to the incidence of anemia in rural China. Should focus on early childhood feeding, nutrition and diet behavior guidance and monitoring, continue to promote the prevention and treatment of infant anemia.
