目标:选择孟加拉整合营养项目运作5年以上的地区为实验地区,非营养实验地区为对照地区,比较儿童营养不良的水平,并评价此项目是否减少2岁以下儿童低体重流行的发生。方法:研究孟加拉6个地区的横断面调查,研究人群共有6820个家庭;按照分层整群抽样的方法抽取6—59个月的儿童7183名,通过Z评分的方法测量中等和严重的低体重,消瘦和生长迟缓的程度,并指导母亲的营养知识学习和实践。结果:2388名6—23个月的儿童和6815名6—59个月的儿童具有完整的测量数据,实验地区和对照地区家庭社会经济变量没有显著差别,实验地区母亲照料儿童程度显著优于对照地区。结论:与非项目覆盖地区相比,没有证据证明孟加拉整合营养项目实现了其减轻低体重患病率40%的目标。
Objectives: To select areas where the Bangladesh Integrated Nutrition Project has been operating for more than 5 years as experimental areas and non-nutrition experimental areas as control areas to compare children’s malnutrition levels, and to evaluate whether this project reduces the incidence of low-weight epidemics in children under 2 years of age. METHODS: A cross-sectional survey was conducted in 6 districts in Bangladesh and the study population was 6820 households; 7183 children aged 6-59 months were sampled by stratified cluster sampling; moderate and severe low body weights were measured by the Z-score method. The degree of weight loss and growth retardation, and guide the mother’s nutrition knowledge learning and practice. Results: 2388 children aged 6-23 months and 6815 children aged 6-59 months have complete measurement data. There is no significant difference in family socioeconomic variables between the experimental and control areas. The extent of mother care in the experimental area is significantly better than that of the control group. area. Conclusion: Compared with non-project coverage areas, there is no evidence that the Bangladesh Integrated Nutrition Project achieved its goal of reducing the prevalence of low-weight by 40%.
