目的：本研究的目的是评估结合计步器和电子邮件支持的校本干预(方案X)对青少年身体活动、久坐行为和健康饮食的影响。方法：采用随机对照试验评估方案X的干预效果。在为期6个月的研究期间，6所学校(N=124名参与者；平均年龄14.1+/-8岁)被随机分配到干预或对照条件下。在基线和6个月随访时测量客观记录的体力活动(平均步数/天)、自我报告的久坐行为和饮食习惯，并用重复测量方差分析和卡方检验评估干预效果。结果：干预组的步数增加了956 4107步/天(男孩)和999 1999步/天(女孩)。重复测量方差分析显示，男孩(F=7.4，p=.01，d=.80)和女孩(F=29.6，p=.80)按时间分组交互作用显著
Purpose: The objective of this study was to evaluate the impact of a school-based intervention (Program X) incorporating pedometers and e-mail support on physical activity, sedentary behavior, and healthy eating in adolescents.Methods: A randomized control trial was used to evaluate the impact of the Program X intervention. Six schools (N = 124 participants; mean age 14.1 +/- .8 years) were randomized to intervention or control conditions for the 6-month study period. Objectively recorded physical activity (mean steps/day), self-reported sedentary behavior, and dietary habits were measured at baseline and at 6-month follow-up and intervention effects were assessed using repeated-measures analysis of variance and chi(2) tests.Results: Participants in the intervention group increased their step counts by 956 4107 steps/day (boys) and 999 1999 (girls). Repeated-measures analysis of variance revealed significant group-by-time interactions for boys (F = 7.4, p = .01, d = .80) and girls (F = 29.6, p
