Although many school-based diet and physical activity interventions have been designed and evaluated, relatively few have been tested for the after-school setting. After-school day-care programmes at either elementary schools or private locations provide a ready-made opportunity for health programmes that may be difficult to incorporate into an already-full school day. The purpose of this paper is to report on a pilot study of an after-school adaptation of the CATCH (Coordinated Approach To Child Health) elementary school programme called the CATCH Kids Club (CKC).
The CKC was pilot-tested and formatively evaluated in 16 Texas after-school programmes: eight in El Paso and eight in Austin (four intervention and four reference sites each). Evaluation consisted of direct observation of moderate to vigorous physical activity during play time, self-reported food intake and physical activity, and focus group interviews with after-school programme staff.
Students responded well to the physical activity and snack components and were less interested in the five-module education component. Routine staff training was a key variable in achieving proper implementation; the ideal would be a full day with repeated follow-up model teaching visits. Staff turnover was a logistic issue, as was programme leader readiness and interest in conducting the programme. Strong and significant effects were observed for the physical activity but not for the education component. The results of the physical education component suggest it is feasible, effective and ready for larger-scale evaluation or dissemination.
尽管已经设计并评估了许多以学校为基础的饮食和体育活动干预措施，但针对校外环境进行测试的相对较少。小学或私立场所的校外日托项目为健康项目提供了一个现成的机会，而这些项目可能难以纳入已经排满的学校日程。本文的目的是报告一项针对名为“儿童健康协调方法”（CATCH）小学项目的校外改编版——“CATCH儿童俱乐部”（CKC）的试点研究。
CKC在德克萨斯州的16个校外项目中进行了试点测试和形成性评估：埃尔帕索有8个，奥斯汀有8个（每个地区各有4个干预站点和4个对照站点）。评估包括在玩耍时间直接观察中度至剧烈的体育活动、自我报告的食物摄入量和体育活动，以及与校外项目工作人员进行焦点小组访谈。
学生们对体育活动和零食部分反应良好，对五个模块的教育部分兴趣较低。常规的工作人员培训是实现正确实施的关键变量；理想的情况是进行一整天的培训，并进行多次后续的示范教学访问。人员流动是一个后勤问题，项目负责人开展该项目的准备情况和兴趣也是如此。观察到体育活动部分有强烈且显著的效果，但教育部分没有。体育教育部分的结果表明，它是可行、有效的，并且已经准备好进行更大规模的评估或推广。
