项目摘要

Abstract Inadequate physical activity and poor diet quality contribute to the high overweight/obesity (OW/O) prevalence in adolescents, aged 12-19 years, indicating a need to intervene at or before age 12. Compared with other adolescents, underserved (minority; low socioeconomic status) adolescents in urban areas exhibit more unhealthy behaviors that increase their risk for obesity and related cardiovascular disease (CVD). Guided by Self-Determination Theory and the Information-Motivation-Behavioral Skills Model, the novel 16-week Guys/Girls Opt for Activities for Life (GOAL) intervention includes 3 components: 1) After-school GOAL Club: 26 120-minute events (2 days/week) for boys and girls that incorporate physical activity and healthy eating and cooking; 2) Three parent-adolescent dyad meetings to empower dyads about physical activity and healthy eating and cooking; and 3) GOAL social networking website so parents can motivate each other to help their adolescents increase physical activity and diet quality. The purpose of this 5-yr group randomized trial (unit of assignment is school) is to evaluate the effect of GOAL on decreasing CVD risk factors (high % body fat, OW/O, low CV fitness), improving quality of life (QOL); and increasing motivation, self-efficacy, and social support to increase MVPA and diet quality among underserved adolescents (5th–7th grade) having BMI z-score ≥0. The long-term goal is to improve the CV health of underserved adolescents to decrease health disparities, a major priority of NHLBI. Eighteen schools will be randomly assigned to receive either GOAL (n=9) or usual school offerings control (n=9) condition. Forty dyads of boys (n=20) and girls (n=20) in each school and one parent per adolescent who is willing to serve as a support person will be enrolled (720 dyads total). Analysis will be based on the intention-to-treat principle. Aims are to evaluate effect of the GOAL intervention, compared to control, on: (1) Improving % body fat (primary outcome) by ≥2.5% between intervention and control adolescents with a BMI z-score ≥0 from baseline (0 months) to 4 months (immediate post-intervention) and to 13 months post-baseline (9-mon. F/U); (2) Increasing secondary proximal outcomes among adolescents: MVPA (via accelerometers; min/hr) and diet quality (healthy eating index based on 3 24-hr dietary recalls) from 0 to 4 months; (3) Improving secondary distal outcomes: CV fitness (Progressive Aerobic CV Endurance Run, [15- or 20-m shuttle run]) from 0 to 4 months; and BMI, OW/O percentage, & QOL from 0 to 4 months and to 13 months; and (4) Increasing social support, self-efficacy, and motivation with evaluation of any mediating effect on adolescent PA and diet quality. An exploratory aim (parents) is to evaluate any effect of GOAL, compared to control, on: (1) Improving parents’ perceived family nutrition and PA, MVPA (via accelerometers), and diet quality (fruit-vegetable-fiber screener) from 0 to 4 months; and (2) Reducing parents’ % body fat and BMI from 0 to 4 months and to 13 months.

抽象的体育锻炼不足和饮食质量差会导致高超重/肥胖症（OW/O）患病率在12-19岁的青少年中，表明需要在12岁或12岁之前进行干预。青少年，服务不足（少数民族；社会经济地位低）城市的青少年暴露了更多不健康的行为增加了其肥胖和相关心血管疾病（CVD）的风险。指导自决理论和信息动机 - 行为技能模型，小说16周男孩/女孩选择生命活动（目标）干预包括3个组成部分：1）课后目标俱乐部： 26个120分钟的事件（2天/周），用于纳入体育锻炼和健康饮食和健康的男孩和女孩烹饪; 2）三个父母青少年会议，以增强有关体育锻炼和健康的二元组饮食和烹饪； 3）目标社交网站，以便父母可以互相激励以帮助他们青少年提高体育锻炼和饮食质量。这个5年组随机试验的目的（单位任务是学校）是评估目标对降低CVD危险因素的影响（高体脂，百分比， OW/O，低简历健身），改善生活质量（QOL）；增强动力，自我效能和社会支持BMI Z分数的服务不足的青少年（5至7年级）的支持以提高MVPA和饮食质量 ≥0。长期目标是改善服务不足的青少年的简历健康，以减少健康差异， NHLBI的主要优先级。十八所学校将被随机分配接受目标（n = 9）或往常学校产品控制（n = 9）条件。每所学校中的四十个男孩（n = 20）和女孩（n = 20），一个愿意担任支持人员的每个青少年的父母将被招募（共有720个二元组）。分析将基于意向性原则。目的是评估目标干预的效果，比较控制：（1）在干预和对照之间将％脂肪％（主要结果）提高≥2.5％ BMI Z分数≥0的青少年，从基线（0个月）到4个月（立即干预后）和至基线后13个月（9个月。F/U）；（2）增加青少年的次要近端结果： MVPA（通过加速度计；最小/小时）和饮食质量（基于3 24小时饮食召回的健康饮食指数） 0到4个月；（3）改善次要远端结果：CV健身（进行性有氧CV耐力运行， [15或20米的班车运行]）从0到4个月；和BMI，OW/O百分比，＆QOL从0到4个月 13个月; （4）通过评估任何调解，提高社会支持，自我效能和动力对青春期PA和饮食质量的影响。探索目的（父母）是评估目标的任何影响，与对照相比，ON：（1）改善父母感知的家庭营养和PA，MVPA（通过加速度计），和饮食质量（可蔬菜纤维筛选器）从0到4个月；（2）减少父母的体内脂肪％和 BMI从0到4个月到13个月。
