Aim: To evaluate the effectiveness on lifestyle change of an mHealth intervention to promote healthy behaviours in adolescence (TeenPower) and to analyse the predictors of the mHealth intervention effectiveness.
Design: This study is designed as a non-randomized controlled trial with a two-arm structure.
Methods: Adolescents of 12-16-year old were recruited from three school districts, with access to the Internet and smartphone/tablet devices. The intervention group was invited to engage in the mHealth intervention (TeenPower) for 6 months in addition to a school-based intervention. The control group only followed the school-based intervention. A repeated measures factorial ANOVA was used and the main effectiveness outcome was the lifestyle change measured by the adolescent lifestyle profile.
Results: The outcomes of the mHealth intervention (TeenPower) show a significant effect on nutrition (ƞ2 p = 0.03, p = .03), positive life perspective (ƞ2 p = 0.04, p = .01), and global lifestyle (ƞ2 p = 0.02, p = .05), with a dropout rate of 62.1%. The analysis of the effectiveness predictors of the mHealth intervention suggested that older adolescents tended to show a significant increase in the rates of stress management (r = .40; p < .05).
Conclusions: Although the considerable dropout rate, the mHealth intervention presented significant impact on multiple lifestyle domains, providing support for the effectiveness of mHealth interventions for health promotion as an add-on to standard interdisciplinary interventions.
Impact: Adolescents must have the necessary and appropriate knowledge for the correct and responsible decision-making regarding their health and lifestyle. Innovative strategies (mHealth intervention) were used to promote healthy behaviours. This study evaluates the effectiveness of an mHealth intervention (TeenPower) specifically designed for adolescents. We found a significant impact in several lifestyle domains such as health responsibility, nutrition, positive life perspective, and global lifestyle.
目的: 评价促进青少年健康行为的移动医疗(mHealth)干预对生活方式改变的作用,并分析移动医疗(mHealth)干预有效性的相关因素。 设计: 该研究被设计为一项非随机对照试验(两组结构)。 方法: 从三个学区招募了12岁~16岁的青少年,他们可以使用互联网和智能手机/平板电脑设备。除接受学校干预外,干预组还接受为期6个月的移动医疗(mHealth)(TeenPower)。对照组仅接受学校干预。采用因素方差分析(factorial ANOVA)重复测量,并且主要影响结果是青少年生活方式发生变化。 结果: 移动医疗(mHealth)干预(TeenPower)的结果显示对营养(ƞ2 p = 0.03, p = .03)、积极生活观(ƞ2 p = 0.04, p = .01)和全球生活方式(ƞ2p = 0.02, p = .05)有显著影响,退学率为62.1%。对移动医疗(mHealth)干预有效性相关因素的分析表明,年龄稍大的青少年的心理压力管理率有显著提高的趋势(r=.40;p<.05)。 结论: 尽管退学率相当高,但移动医疗(mHealth)干预对多个生活方式领域产生了重大影响,支持移动医疗(mHealth)干预作为附加的标准跨学科干预手段对促进健康的有效性。 影响: 青少年必须具备必要和适当的知识,能够作出与其健康生活方式相关的正确且负责任的决定。创新策略(mHealth干预)用于促进健康行为。该研究评估了专为青少年设计的健康干预(TeenPower)的有效性。我们发现,该等干预在诸如健康责任、营养、积极生活观和全球生活方式等生活方式领域有着重大影响。.
