Preventing obesity and cardiovascular disease at early ages is important; however, few effective interventions for early adolescents have been reported. In this study, low-income, culturally diverse students from an urban middle school (n = 60) received four classroom interventions with the use of a combined Health Promotion/Transtheoretical Model to control fat in diet and increase physical activity. A control group (n = 57) received the usual classroom education. Pretest percentage fat in diet was regressed on demographics, access to low-fat foods, perceived self-efficacy, benefits/barriers, and stage of change with results as proposed by the model [F(9,64) = 5.77; p =.000; adjusted R(2) = 0.35]. Posttest percentage fat in food was significantly less for the intervention group as compared with the control group (t = 2.06; df, 115; p =.04).
在早年预防肥胖和心血管疾病很重要；然而，针对青少年早期的有效干预措施鲜有报道。在本研究中，来自一所城市中学的低收入、文化背景多样的学生（n = 60）接受了四项课堂干预，采用健康促进/跨理论模型相结合的方法来控制饮食中的脂肪并增加体育活动。一个对照组（n = 57）接受常规课堂教育。根据人口统计学、获取低脂食品的机会、自我效能感、益处/障碍以及模型所提出的变化阶段，对饮食中脂肪的预测试百分比进行回归分析，结果为[F(9,64) = 5.77；p =.000；调整后R(2) = 0.35]。与对照组相比，干预组食物中脂肪的后测试百分比显著更低（t = 2.06；自由度，115；p =.04）。
