The Effects of Two Influential Early Childhood Interventions on Health and Healthy Behaviour
研究评估了佩里学前项目和卡罗来纳初学者项目两项美国早期儿童干预对成年后健康和健康行为的长期影响，发现对男孩效果更显著，且改善童年特质的作用超过提高成年社会经济地位的作用。
This paper examines the long-term impacts on health and healthy behaviors of two of the oldest and most widely cited U.S. early childhood interventions evaluated by the method of randomization with long-term follow-up: the Perry Preschool Project (PPP) and the Carolina Abecedarian Project (ABC). There are pronounced gender effects strongly favoring boys, although there are also effects for girls. Dynamic mediation analyses show a significant role played by improved childhood traits, above and beyond the effects of experimentally enhanced adult socioeconomic status. These results show the potential of early life interventions for promoting health.
