OBJECTIVES: To describe the burden of anemia at 6 to 11 months and the change in anemia prevalence after 1 year of multi-micronutrient supplementation. METHODS: We analyzed hemoglobin concentration twice in 569 children. First when they were 6 to 11 months old and second after 1 year (at ages 18-23 months). All children were given a lipid-based micronutrient formulation daily for a year. RESULTS: The prevalence (95% CI) of anemia at 6 to 11 months was 65% (61%-68%) and decreased to 25% (21%-28%) after 1 year. Among the 367 infants with anemia at baseline, 29% continued to be anemic during follow-up. There were also 18% infants who developed anemia during follow-up out of 202 infants with normal hemoglobin concentration at baseline. CONCLUSIONS: The anemia prevalence was substantially reduced after 1 year with micronutrient supplementation. However, even after 1 year of multimicronutrient supplementation, one-fourth of toddlers had anemia which merits further integrated research and comprehensive intervention.
目的:描述6至11个月龄时贫血的负担以及补充多种微量营养素1年后贫血患病率的变化。 方法:我们对569名儿童的血红蛋白浓度进行了两次分析。第一次是在他们6至11个月大时,第二次是在1年后(18至23个月龄)。所有儿童每天服用基于脂质的微量营养素制剂,为期一年。 结果:6至11个月龄时贫血的患病率(95%CI)为65%(61%-68%),1年后降至25%(21%-28%)。在基线时患有贫血的367名婴儿中,29%在随访期间仍患有贫血。在基线时血红蛋白浓度正常的202名婴儿中,也有18%在随访期间出现贫血。 结论:补充微量营养素1年后,贫血患病率大幅降低。然而,即使在补充多种微量营养素1年后,仍有四分之一的幼儿患有贫血,这值得进一步开展综合研究和全面干预。
