CATCH PHASE III--TRACKING FIELD STUDY SITE

儿童和青少年心血管健康试验 （CATCH）是一项为期7.5年（1987-1995）的多中心随机干预研究 在96所学校试用。 CATCH旨在评估 以学校为基础的多元干预， 小学生（3至5年级）的健康行为， 降低他们随后患心血管疾病的风险。 CATCH是 最大、最全面的小学健康教育研究 项目曾经进行测试的效果纵向 在学校的干预。 在CATCH干预阶段（第二阶段）， 观察到了对中间变量的影响。 主试验 结果仍在分析中。 竞争延续提出 延长4年随访期，以便继续测量 对13到14岁的同龄人进行研究。 CATCH的主要目标 第三阶段：跟踪是双重的。 CATCH将测试以下假设： 维持干预对生理、行为和 青少年早期的心理社会风险因素（第6至第8 等级）。 第二，CATCH III：跟踪将连续观察 心血管危险因素的发生、发展和相互关系 从青春期早期到中期， 的学生。 继续跟踪这一队列将创造机会来评估 青春期前的干预是否可以维持行为和风险 因素水平的变化在青春期早期，众所周知的关键 大多数积极健康行为的衰退期。 这项研究是 旨在扩大对课程和决定因素的理解， 生理、行为和心理社会风险因素 心血管疾病 第三条：追踪将有足够的样本 在重要的人口统计学分组中检查单独的结果， 男性对女性，白人对黑人对西班牙裔。

DESCRIPTION: The Child and Adolescent Trial for Cardiovascular Health (CATCH) is a 7.5 year (1987-1995) multi-site, randomized intervention trial in 96 schools. CATCH was designed to evaluate the effectiveness of a multiple component school- based intervention for promoting healthful behaviors in elementary school children (grades 3 to 5) to reduce their subsequent risk for cardiovascular disease. CATCH is the largest, most comprehensive elementary school health education research project ever undertaken testing the efficacy of longitudinal interventions in schools. During the CATCH intervention phase (Phase II) significant positive effects on intermediate variables have been observed. The main trial outcomes are still under analysis. The competing continuation proposes a four-year extended follow-up period to allow continued measurements on the cohort through ages 13 to 14 years old. The main goals of CATCH Phase III: Tracking are two-fold. CATCH will test the hypothesis of maintenance of intervention effects on physiologic, behavioral, and psychosocial risk factors through early adolescence (6th through 8th grade). Second, CATCH III: Tracking will descriptively observe the onset, development, and inter-correlation of cardiovascular risk factors from early to middle adolescence on a large, ethnically diverse group of students. Continuing to follow this cohort will create the opportunity to assess whether a pre-adolescent intervention can sustain behavioral and risk factor level changes during early adolescence, the well known critical period of decline of most positive health behaviors. The study is intended to broaden the understanding of the course and determinants of physiologic, behavioral, and psychosocial risk factors for cardiovascular disease. CATCH III: Tracking will have adequate sample to examine separate findings among important demographic subgroups such as, males versus females, and Whites versus Blacks versus Hispanics.
