婴幼儿的血红蛋白水平与母亲贫血的关系

目的探讨≤3岁婴幼儿血红蛋白水平与母亲贫血的关系,为改善婴幼儿和母亲的贫血状况提供科学依据。方法采用多阶段分层整群随机抽样的方法,样本均来自同一家庭中的母子(女),调查对象一一配对。为了保证婴幼儿和乳母的调查人数,在样本地区适当补充了调查人数。结果城乡≤3岁儿童的贫血患病率分别为26．9％(94／350)和32．4％(594／1835),3岁及以下贫血儿童的出生体重(3266±579)g低于非贫血儿童(3310±501)g;贫血儿童出生体重<2500 g的比例显著高于非贫血儿童,调查时贫血儿童未断奶率显著高于非贫血儿童。血红蛋白水平<100g/L的婴幼儿占7．6％(166／2185),血红蛋白水平<110g／L的婴幼儿占24．9％(544／2185)。贫血母亲和非贫血母亲养育的3岁及以下城乡儿童的血红蛋白水平分别为(115．6±17．4)g／L、(115．2±16．7)g／L和(123．3±14．9)g/L、(122．2±15．3)g/L,差异有统计学意义(P<0．001),非贫血母亲3岁及以下儿童的血红蛋白曲线向右偏移。母亲血红蛋白水平越高,其子女的血红蛋白水平曲线向右偏移越明显。结论≤3岁儿童的血红蛋白水平与母亲的血红蛋白水平相关。

Association between hemoglobin level of children < or = 3 years and anemia of their mother

OBJECTIVE: To study the relationship between the hemoglobin level of children < or = 3 years and anemia of their mothers. METHODS: Multi-steps cluster sampling was adopted. In order to ensure sufficient number of babies and young children and postpartum in this survey, additional subjects were included in the sample. The subjects in study were collected in the same family. RESULTS: The average anemia prevalence of children < or = 3 years was significant different between urban and rural (26.9%, 94/350 and 32.4%, 594/1835, P < 0.05) areas. The birth weight of anemia children < or = 3 years was significant lower than noanemia children (P < 0.05); the incidence of low birth weight of anemia children < or = 3 years was significant higher than noanemia children (P < 0.05); the percentage of Hb < 100 g/L and < 110 g/L were 7.6% (166/2185) and 24.9% (544/2185); the Hb levels of children fed by anemia mother and noanemia mother were significantly different (115.6 +/- 17.4) g/L, (115.2 +/- 16.7) g/L and (123.3 +/- 14.9) g/L, (122.2 +/- 15.3) g/L, P < 0.001. CONCLUSION: There should be significant relation between the Hb level of children < or = 3 years and anemia of their mother.
