目的分析通过给家长提供贫血等营养健康信息的方式解决贫困农村学生贫血问题的可行性,探索提高贫困学生血红蛋白水平的新思路。方法在陕西省9个贫困县42个农村学校中,随机选取12所学校进行信息干预,对这些学校四年级学生的家长进行儿童贫血方面知识的培训,其他学校作为对照组。通过对比干预前后干预组和对照组间血红蛋白水平的差异,分析健康信息干预对提高贫困地区学生血红蛋白水平、减少贫血率的作用。结果贫困农村地区学龄儿童贫血率较高,为21.6%;寄宿学生和12岁及以上学生表现更为严重,贫血率分别为25.6%,38.5%。家长健康信息干预对提高贫困农村非寄宿学生血红蛋白水平有一定效果,非寄宿学生血红蛋白水平均增加1.2 g/L;但对寄宿学生的效果不显著。结论贫困农村学生贫血问题较严重,通过信息干预虽然能部分解决非寄宿学生贫血问题,但如何解决寄宿学生的贫血问题需要进一步探索。
Objective To analyze the feasibility of providing anemia and other nutritional health information to parents in poor rural areas and probe into ways to improve the hemoglobin level of poor students. Methods Twelve schools were randomly selected from 42 rural schools in 9 poverty-stricken counties of Shaanxi Province for information intervention. Parents of fourth-grade students in these schools were trained in knowledge about childhood anemia. Other schools served as control group. By comparing the differences of hemoglobin levels between the intervention group and the control group before and after intervention, the effect of health information intervention on improving hemoglobin level and reducing the anemia rate in poor areas was analyzed. Results The incidence of anemia among school-age children in impoverished rural areas was high (21.6%). Boarding students and students aged 12 and over were even more severely affected with anemia rates of 25.6% and 38.5%, respectively. Parental health information intervention had some effect on improving hemoglobin level of non-native rural students in poor rural areas. The hemoglobin level of non-boarding children increased by 1.2 g / L, but not significant for boarding students. Conclusion The problem of anemia in poor rural students is more serious. Although information intervention can partially solve the problem of anemia in non-boarding students, how to solve the problem of anemia in boarding students needs to be further explored.
