Background. The aim was to evaluate the effects of a 12-week, Facebook-delivered lifestyle counselling intervention, with or without physical activity self-monitoring, on physical activity and body mass index (BMI) in overweight and obese 13-16-year-old adolescents. Methods. Three-arm randomized controlled trial. Participants (n = 46) were randomly assigned to intervention and control groups: one group received Facebook-delivered lifestyle counselling and monitoring of their physical activity (Fb + Act, n = 15), whereas a second experimental group received the same Facebook-delivered lifestyle counselling without self-monitoring (Fb, n = 16) and a third group served as the control group (n = 15). Objective and self-reported physical activity assessment were used. Nonparametric statistical tests were used. Results. There were no significant intervention effects in terms of changes in physical activity levels or BMI from baseline to the 12-week postintervention measurements between the intervention and control groups. The Fb + Act group had lower sedentary time on weekdays compared to the control group during postintervention measurements (p = 0.021), but there was no interaction between time and group. Conclusions. Interventions were not effective at increasing physical activity in overweight and obese adolescents. Before implementing such interventions, more evaluations on their effectiveness are needed. This trial is registered with ClinicalTrials.gov identifier NCT02295761 (2014-11-17).
背景。本研究旨在评估一项为期12周、通过脸书提供的生活方式咨询干预措施（有无身体活动自我监测）对13至16岁超重和肥胖青少年身体活动及体重指数（BMI）的影响。方法。三臂随机对照试验。参与者（n = 46）被随机分配至干预组和对照组：一组接受通过脸书提供的生活方式咨询及身体活动监测（Fb + Act，n = 15），而另一实验组接受相同的通过脸书提供的生活方式咨询但无自我监测（Fb，n = 16），第三组作为对照组（n = 15）。采用客观及自我报告的身体活动评估方法。使用非参数统计检验。结果。从基线到干预后12周测量，干预组和对照组在身体活动水平或BMI变化方面无显著干预效果。干预后测量期间，Fb + Act组工作日久坐时间低于对照组（p = 0.021），但时间与组间无交互作用。结论。干预措施在增加超重和肥胖青少年身体活动方面无效。在实施此类干预措施之前，需要对其有效性进行更多评估。本试验已在ClinicalTrials.gov注册，标识符为NCT02295761（2014 - 11 - 17）。
