背景。本研究报告了对青春期男性体力活动水平进行为期 9 周干预的结果。方法。参与者是 473 名 10 至 14 岁的休斯顿童子军（42 名士兵），士兵被随机分配到干预或控制条件下。数据收集于 2003 年春季（16 名士兵）和秋季（26 名士兵）两波。干预参与者接受了为期 9 周的部队和互联网计划，以提高身体活动技能、自我效能和目标设定。通过加速度计在基线、干预结束（Post#I）和 6 个月后（Post#2）时评估体力活动。计算久坐、轻度和中度至剧烈体力活动的分钟数。我们进行了重复测量分析，以测试参与者在部队中的各组之间随着时间的推移身体活动的差异。结果。接近显着性（P = 0.051）的三向交互（组 * 时间 * 波）表明春季干预参与者的久坐行为减少了 12 分钟。显着的三向交互作用 (P = 0.011)（组 * 时间 * 波）表明春季干预组的光强度活动增加了 12 分钟。结论。参与“健康生活”徽章计划后，仅春季参与者的久坐行为出现小幅减少，轻度体力活动增加的趋势。对中度至剧烈的体力活动没有影响。 (c) 2005 Elsevier Inc. 保留所有权利。
Background. This study reports the results of a 9-week intervention on the physical activity levels of adolescent males.Methods. Participants were 473 10- to 14-year-old Houston Boy Scouts (42 troops) with troops randomly assigned to intervention or control conditions. Data were collected in spring (16 troops) and fall (26 troop) waves during 2003. Intervention participants received a 9-week troop and Internet program to increase physical activity skills, self-efficacy and goal-setting. Physical activity was assessed at baseline, end of the intervention (Post#I) and post-6 months (Post#2) by accelerometer. Minutes of sedentary, light and moderate to vigorous physical activity were calculated. Repeated measure analyses were performed to test differences in physical activity over time between groups with participants nested in troops.Results. A three-way interaction (group * time * wave) that approached significance (P = 0.051) indicated a 12-min reduction in sedentary behavior among spring intervention participants. A significant three-way interaction (P = 0.011) (group * time * wave) indicated a 12-min increase in light intensity activity among the spring intervention group.Conclusion. Participation in the Fit for Life badge program resulted in a trend towards a small decrease in sedentary behavior and increased light intensity physical activity among spring participants only. There was no effect on moderate to vigorous physical activity. (c) 2005 Elsevier Inc. All rights reserved.
