Effectiveness of Tailored Multichannel Interventions on Weight Loss Among Adolescents: A Randomized Controlled Trial

Summary

overweight among adolescents is a public health issue. However, several weight loss interventions were developed and conducted for adolescents. These interventions are often not adequately tailored to the needs of this vulnerable target group. Besides, these interventions proposed one channel is adequate to deliver the message to adolescents.

The proposed study aims to evaluate the effectiveness of tailored multichannel interventions on weight loss among adolescents.

The proposed study is a prospective, cluster-randomized controlled trial. 279 adolescents will be recruited from 8 non-medical colleges in Mansoura University. The 8 colleges will be randomly assigned to 4 colleges for the tailored multichannel nursing intervention or 4 colleges as a control group. For intervention participants, the tailor-based intervention will be designed and guided by a health belief model and take into evidence-based recommendations. The intervention will be designed by a multidisciplinary team and will be administered by 8 nurses for 5 months, including five face-to-face school meetings, five school-based telephone calls, and five WhatsApp text messages. Control group participants will receive 2 non-tailored face-to-face sessions. The primary outcome is the mean difference in weight loss between groups. The proposed study hypothesizes that the participants who will receive tailored multichannel intervention will lose significantly more weight (Body Mass Index) compared with the control group. Secondary outcomes include a health belief model.

Tailored Multichannel interventions

To ensure the feasibility of the intervention, the intervention will be designed by an interdisciplinary team including academic researchers from different specialties (experts in the fields of community health, psychiatry health, and nutrition), as well as 3 research assistants. The designing process for each individual in the intervention group involved the following 4 subsequent steps: (1) intervention nurses assess HBM constructs, which are used to collect data on each unique perception regarding overweight(Saghafi-Asl et al., 2020). (2) data are reviewed, identified, and summarized by the interdisciplinary team; (3) the interdisciplinary team then creates an intervention plan based on the summarized needs and (4) the intervention plan will be shared with the participant to ensure collaboration. The intervention will adopt the strategies of the Diabetes Prevention Program (DDP) (The Diabetes Prevention Program (DPP), 1996).
