There are few studies of community growth promotion as a means of addressing malnutrition that are based on longitudinal analysis of large-scale programmes with adequate controls to construct a counterfactual. The current study uses a difference in difference comparison of cohorts to assess the impact on the proportion of underweight children who lived in villages receiving services provided by the Senegal Nutrition Enhancement Project between 2004 and 2006. The project, designed to extend nutrition and growth promotion intervention into rural areas through non-governmental organisation service providers, significantly lowered the risk of a child having a weight more than 2 sd below international norms. The odds ratio of being underweight for children in programme villages after introduction of the intervention was 0.83 (95% CI 0.686, 1.000), after controlling for regional trends and village and household characteristics. Most measured aspects of health care and health seeking behaviour improved in the treatment relative to the control.
很少有基于大规模项目的纵向分析且有适当对照以构建反事实的研究，将促进社区发展作为解决营养不良问题的一种手段。本研究采用队列差异比较法，评估2004年至2006年期间，塞内加尔营养改善项目为村庄提供服务对体重不足儿童比例的影响。该项目旨在通过非政府组织服务提供者将营养和生长促进干预扩展到农村地区，显著降低了儿童体重超过国际标准2个标准差以上的风险。在控制了区域趋势以及村庄和家庭特征后，干预实施后项目村庄儿童体重不足的比值比为0.83（95%置信区间0.686, 1.000）。与对照组相比，治疗组在大多数衡量的医疗保健和就医行为方面都有所改善。
