摘要目的分析综合干预对6～35月龄留守儿童营养不良改善的效果。方法采用类实验设计。数据来源于儿童早期综合发展项目基线和干预后调查。项目于2014—2016年在晋黔两省四县的80个村开展,为6～35月龄儿童及其看护人提供包括营养包补充、婴幼儿喂养咨询指导及回应性照护在内的综合干预。分别选取同省具有相似经济发展水平的一个县为对照县,共选取对照县2个。干预县接受项目干预和常规保健服务,对照县仅接受常规保健服务。于2013年和2016年7～9月分别抽取干预县40个村、对照县43个村,以样本村中全部6～35月龄儿童及其看护人为调查对象进行基线和干预后调查。采用双重差分模型,控制时间变化、基线差异及看护人、留守儿童社会人口学特征,估计干预对留守儿童看护人喂养行为及留守儿童营养改善效果。结果基线期分别纳入干预组695 对、对照组478 对、终末期纳入740对、对照组514 对6～35月龄留守儿童及其看护人样本进行分析。与对照组相比,干预降低了23～29月龄留守儿童发生营养不良的风险(OR:0.30, 95% CI:0.10~0.91)。结论综合干预对23～29月龄留守儿童营养不良状况改善有效。建议结合全国贫困地区营养包提升行动,提高干预依从性,促进留守儿童营养处于适宜水平。

Abstract：Objective To investigate the effects of the integrated interventions on caregivers' feeding practices on the undernutrition status of left-behind children (LBC) aged 6-35months.Methods A quasi-experimental design was applied in our study. Baseline and follow-up surveys of the Integrated Early Childhood Development (IECD) project were used for this study. The IECD project was implemented in 80 villages within four counties in provinces of Shanxi and Guizhou, from 2014 to 2016. The project provided integrated nutritional supplement (also known as Ying Yang Bao [YYB]), feeding consults and responsive healthcare for children aged 6-35 months old. In this study, in each province, the two counties were similar in economic statuses; one was selected as the control group and the other was the intervention group. Standard healthcare was provided for all participants. The intervention group also received the project interventions, additionally. Finally, the intervention group included 40 villages and the control included 43 villages. All children aged of 6-35 months and their caregivers in the selected villages were investigated twice during Jul.-Sep. in 2013 and 2016. Difference-in-difference (DID) model was employed to adjust the baseline difference, time trend and other potential confounding factors between the intervention group and the control group to estimate the effects.Results LBC aged 6-35 months and their caregivers were selected. At the baseline visit, there were 695 parent-child dyads in intervention group, and 478 dyads in control group at baseline. At the follow-up visit, there were 740 dyads in intervention, and 514 dyads in control. According to the DID model, the IECD intervention reduced the risk of undernutrition among the LBC aged 23-29 months (aOR:0.30; 95%CI:0.10, 0.91). However, the effect was not statistically significant among the LBC aged 6-35 months (P>0.05).Conclusion The integrated interventions effectively reduced the undernutrition prevalence for LBC aged 23-29 months old. The current YYB supplement could be used as a platform to improve the interventions for the optimal nutrition of LBC.
