Early Stimulation and Nutrition: The Impacts of a Scalable Intervention

Early Childhood Development is becoming the focus of policy worldwide. However, the evidence on the effectiveness of scalable models is scant, particularly when it comes to infants in developing countries. In this paper we describe and evaluate with a cluster-RCT an intervention designed to improve儿童早期发展（Early Childhood Development）正成为全球各国政策关注的焦点。然而，目前关于可规模化干预模式有效性的实证证据仍较为匮乏，针对发展中国家婴幼儿群体的相关研究尤为不足。本文采用整群随机对照试验（cluster-RCT）方法，对一项旨在改善的干预措施进行了描述与评估。
