目的探讨辅食营养补充品对婴幼儿血红蛋白(Hb)和贫血的改善作用。方法通过基线调查从浙江省温州、嘉善、余杭三地随机选取4~30个月婴幼儿292名,测定身长、体重及血红蛋白水平。随机分成两组,在保留其家庭习惯的辅助食物添加的前提下,干预组每天添加营养包1包,对照组采取空白对照,随访3个月后再次测量身长、体重和血红蛋白。结果随访3个月后,干预组与对照组儿童身长、体重增长情况无明显差异(P﹤0.05);干预组儿童Hb增加高于对照组,贫血率明显下降,差异有统计学意义(P﹤0.05)。结论添加辅食营养补充品可以改善婴幼儿的血红蛋白,降低其贫血发生率。
Objective To investigate the effects of supplementary food supplement on hemoglobin (Hb) and anemia in infants and young children. Methods A total of 292 infants from 4 to 30 months were randomly selected from Wenzhou, Jiashan, Yuhang, Zhejiang Province through baseline survey to measure body length, body weight and hemoglobin. The patients were randomly divided into two groups. One packet of nutrition packs was added to the intervention group on a day-by-day basis, while the control group was given blank control. After three months of follow-up, the body length, body weight and hemoglobin were measured again. Results After 3 months of follow-up, there was no significant difference in body height and weight gain between the intervention group and the control group (P <0.05). The Hb level in the intervention group was higher than that in the control group, and the anemia rate was significantly decreased (P < 0.05). Conclusion Supplementary dietary supplements can improve hemoglobin in infants and young children and reduce the incidence of anemia.
