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.

摘要 体力活动不足和饮食质量差是超重/肥胖(OW/O)高患病率的原因 在12-19岁的青少年中，表明需要在12岁或之前进行干预。与其他 服务不足(少数民族；社会经济地位较低)的青少年在城市地区表现出更多 不健康的行为会增加肥胖和相关心血管疾病(CVD)的风险。指导原则 自我决定理论和信息动机行为技能模型，小说《16周》 男孩/女孩选择生活活动(目标)干预包括3个组成部分：1)课后目标俱乐部： 为男孩和女孩举办的26项120分钟的活动(每周2天)，包括体力活动和健康饮食，以及 烹饪；2)三次亲子两栖会议，让双亲了解体育活动和健康 吃饭和做饭；以及3)目标社交网站，这样父母就可以相互激励，帮助他们 青少年增加体力活动和饮食质量。这项为期5年的随机分组试验的目的 任务是评估目标对降低心血管疾病危险因素(高百分比体脂， W/O，低CV适合度)，提高生活质量(QOL)；以及增加动力、自我效能和社交 支持在有BMI z-Score的服务不足的青少年(5-7年级)中提高MVPA和饮食质量 ≥0。长期目标是改善未得到充分服务的青少年的简历健康，以减少健康差距， NHLBI的一个主要优先事项。18所学校将被随机分配到目标学校(n=9)或正常学校 学校提供控制(n=9)情况。每所学校40对男生(n=20)和女生(n=20)和1 每个愿意担任支持人员的青少年的父母将被录取(总共720个二元组)。分析 将以意向治疗原则为基础。目的是评价目标干预的效果，比较 为了控制：(1)在干预和对照之间，提高体脂百分比(主要结果)≥2.5% 体重指数z-≥为0的青少年，从基线(0个月)到4个月(干预后立即)，到 基线后13个月(9个月F/U)；(2)青少年的次级近期结局增加： MVPA(通过加速计；分钟/小时)和饮食质量(基于3个24小时饮食召回的健康饮食指数) 0-4个月；(3)改善次要远端结果：CV适合性(渐进式有氧CV耐力跑， [15米或20米穿梭])0至4个月；0至4个月及以下的BMI、OW/O百分比及生活质量 13个月；(4)增加社会支持、自我效能感和动机，并对任何中介进行评估 对青少年PA和饮食质量的影响。探索性目标(父母)是评估目标的任何效果， 与对照组相比，在以下方面：(1)改善父母的家庭营养和PA、MVPA(通过加速计)、 和饮食质量(水果-蔬菜-纤维筛选器)从0到4个月；(2)降低父母的体脂百分比和 体重指数0~4个月和13个月。
