CARDIOVASCULAR RISK REDUCTION IN TENTH GRADERS

心血管疾病开始于生命早期，但可能会被预防或推迟 通过为年轻人设计的初级预防方案。建议数 研究将开发、实施和测试以学校为基础的多组件 针对15岁高中生的健康行为改变计划。四 学校将被随机分配到干预和控制条件下。 干预将在两个队列中向青少年提供(从1到2 从84年9月开始，C2从85年9月开始)。班杜拉的社会学习模式， 强调技能发展和绩效，将提供 为我们的干预提供理论依据。 拟议的项目旨在确定(1)建筑的方法 自我调节能力，让学生养成健康的生活方式 行为，(2)减少心血管危险因素行为和 增加健康行为；(3)降低危险因素变量。这个 计划将由一系列模块组成，旨在(1)介绍 大学生对健康生活理念和养成健康的价值 生活方式；(2)帮助学生获取有关健康的具体信息 各种风险因素行为和做法的风险/收益；(3)帮助 学生获得认知和行为技能以改变自己 行为和影响家庭和社会环境；(4)提供 在实践中使用这些技能来增强感知的能力 他们成功地做出改变的能力；以及(5)在 发明和使用“抵抗”技能来对抗诱因回归 旧习惯，因此，改善维护和推广 新技能。 自我报告措施将包括：健康习惯调查，感知 自我效能感、食物频率清单和体力活动清单。 生理测量将包括皮褶厚度、静息血液 压力、阶梯测试和呼出空气一氧化碳。

Cardiovascular disease begins early in life but may be prevented or delayed by primary prevention programs designed for young people. The proposed research will develop, implement, and test a school-based multicomponent health behavior change program for 15-year old high school students. Four schools will be randomly assigned to intervention and control conditions. The intervention will be delivered to adolescents in two cohorts (Cl to begin in 09/84 and C2 to begin in 09/85). Bandura's social learning model, emphasizing skills development and performance, will provide the theoretical unterpinnings for our intervention. The proposed project is designed to indentify methods for (1) building self-regulatory skills to enable studenst to develop healthy lifestyle behaviors, (2) decreasing cardiovascular risk factor behaviors and increasing healthy behaviors, and (3) to lower risk factor variables. The program will be comprised of a series of modules designed to (1) introduce students to healthy living concepts and the value of adopting healthy lifestyles; (2) help students acquire specific information on the health risk/benefits of a variety of risk factor behaviors and practices; (3) help students to acquire cognitive and behavioral skills for changing their own behavior and influencing family and social environments; (4) provide practice in the use of these skills to bolster perceived competence in their ability to make changes successfully; and (5) provide practice in the invention and use of "resistance" skills to combat inducements to return to old habits and in consequence, to improve maintenance and generalization of new skills. Self-report measures will include: health habits survey, perceived self-efficacy, food frequency checklist, and physical activity checklist. Physiological measures will include skinfold thickness, resting blood pressure, step test, and expired air carbon monoxide.
