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 (ƞ2p = 0.03, p = .03), positive life perspective (ƞ2p = 0.04, p = .01), and global lifestyle (ƞ2p = 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.
This instrument is useful as an evaluation tool for health-promoting lifestyles and as an instrument for testing the effectiveness of health-promoting programs.
The ALP Portuguese version is a psychometrically reliable, valid, and useful measurement instrument for assessing health-promoting lifestyles in adolescence. The ALP is cross-culturally validated and can decisively contribute to a better understanding of adolescent health promotion needs. Additional research is needed to evaluate the instrument's predictive validity, as well as its clinical relevance for practice and research.
Aim: This paper describes the design and rationale of multicenter practice-based research that aims to develop and evaluate an innovative mobile health (mHealth) intervention programme directed to promote healthy behaviours and prevent adolescent obesity.Design: This study is designed as a non-randomized controlled trial with a threearm structure.Methods: Twelve to 16 years old participants will be recruited from schools, with access to the Internet and smartphone/tablet devices. The intervention group will be invited to engage in the TeenPower mHealth programme and divided into two subgroups: Group A (additionally engaged in a structured school-based intervention programme) and Group B (only engaged in the mHealth programme). The mHealth app includes educational resources, self-monitoring, social support, interactive training modules and motivational tools. The control group will only follow the structured school-based intervention programme. The intervention length will be 3 months, including the direct support of an interdisciplinary team (nursing, nutrition, sports, psychology, among others). This research was approved and funded in August 2017.
Discussion:The positive evaluation of the intervention programme will stimulate the inclusion of technologies in the promotion of salutogenic behaviours and obesity prevention.Impact: Adolescent obesity reached epidemic proportions. It is urgent to find effective prevention strategies to induce change at the individual, family and community level. If effective, this protocol can be used by health and exercise professionals in improving community interventions tailored to teenagers.
Adolescent obesity is a major health problem. The need for effective adolescent weight management programs is of high clinical and public health relevance. This study evaluates the effectiveness of an e-therapeutic platform (Next.Step), aiming to promote weight management skills and the adoption of health-promoting lifestyles. This nonrandomized clinical trial with control group uses a sample of 94 adolescents who attended a paediatric obesity clinic. The experimental group was invited to access the platform Next.Step during 24 weeks, in addition to the standard treatment program. The control group followed the standard treatment protocol and joined a waiting list. Overall, the outcomes of the e-therapeutic program were not substantially better than those obtained with a traditional kind of intervention despite the intervention being associated with an improved health responsibility score (d = 0.51; p = 0.014). Several predictors of the Next.Step effectiveness were found.Conclusion: Although the e-therapeutic program led to a significant increase in health responsibility, inconclusive results were found regarding the program effectiveness compared to the standard multidisciplinary intervention. The lack of significant differences between groups may be due to the reduced rates of program adherence and the high dropout rate.
What is Known:
• Adolescent obesity has reached epidemic proportions, and standard treatment programs have been unable to achieve the desired adherence so far.
• Internet-based programs have already shown positive results in the adult obese population, but information is scarce regarding adolescents.
What is New:
• This study assesses the effectiveness of a structured case management program including communication technologies on both the behavioural change and the health of obese adolescents.
• The e-therapeutic program led to an increase in health responsibility.
The results of this research will promote reflection on new approaches directed to treat adolescent obesity and on the promotion of healthy behaviours. We expect to gather empirical evidence of the intervention programme effectiveness. The expectations lie on the population health gains, empowerment in decision-making and adoption of healthier lifestyles.
