背景资料：激励青少年与技术选择健康（TM）（匹配）已提供了八年的北卡罗来纳州中学高肥胖患病率。方法：七年级教师在两所学校提供匹配的教训，在2009年，与一个控制学校。2013年，学生们重新测量并完成了一项健康行为调查。结果包括BMI、BMI z评分（zBMI）、体重类别和自我报告的行为。比较采用t检验（连续测量），Fisher精确检验（分类测量）和线性混合模型（组间趋势）。结果：在原始参与者中，MATCH组104/189（55%）和对照组117/173（68%）进行了重新测量。在对照组中，保留参与者的基线BMI较低，白色百分比较高。在所有参与者中，MATCH组zBMI降低（平均变化为-0.15，SD = 0.60），对照组zBMI升高（平均变化为0.04，SD = 0.52）;组间p = 0.02。在所有超重亚组的混合模型中，MATCH的zBMI随时间呈下降趋势，与对照组有显著差异（斜率MATCH-0.0036 vs对照组0.0009; p = 0.01）。对于体重类别的变化：MATCH组肥胖发生率（13%）低于对照组（39%）; MATCH组超重缓解至健康体重（40%）高于对照组（26%）。MATCH参与者自我报告的频率较低的摄入量的甜味饮料和零食和小时的平日电视时间比control students.Conclusions：MATCH参与可以导致长期预防肥胖相比，控制，差异自我报告的健康行为的变化，以支持一个潜在的机制，观察到的BMI差异。
Background: Motivating Adolescents with Technology to CHOOSE Health (TM) (MATCH) has been provided for eight years in North Carolina middle schools with high obesity prevalence.Methods: Seventh grade teachers in two schools delivered MATCH lessons in 2009, with one control school. In 2013 students were remeasured and completed a health behavior survey. Outcomes include BMI, BMI z-score (zBMI), weight category, and self-reported behaviors. Comparisons used t tests (continuous measures), Fisher's exact test (categorical measures), and linear mixed models (trend between groups).Results: Of original participants, 104/189 (55%) of MATCH and 117/173 (68%) of control were remeasured. In the control group, retained participants had lower baseline BMI and were higher percent white. Among all participants, zBMI decreased in MATCH (mean change -0.15 with SD = 0.60) and increased in control (mean change 0.04 with SD = 0.52); between groups p = 0.02. In mixed models for the all overweight subgroup, MATCH had a downward trend in zBMI over time that was significantly different from control (slope MATCH -0.0036 versus control 0.0009; p = 0.01). For shifts in weight category: incidence of obesity was lower in MATCH (13%) versus control (39%); remission of overweight to healthy weight was greater in MATCH (40%) versus control (26%). MATCH participants self-reported lower frequency of intake of sweetened beverages and snacks and hours of weekday TV time than control students.Conclusions: MATCH participation can result in long-term prevention of obesity compared to control, with differences in self-reported health behavior changes to support an underlying mechanism for the observed BMI differences.
