Data from: Effectiveness of tailored multichannel interventions on weight loss among adolescents: A Randomized controlled trial

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 that 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, randomized controlled trial. 279 adolescents were recruited
from 8 non-medical colleges in Mansoura University. For
intervention participants, the tailored intervention is designed and
guided by a health belief model and takes into account evidence-based
recommendations. The intervention was designed by a multidisciplinary team
and administered by 10 nurses for 5 months, including five face-to-face
school meetings, five school-based telephone calls, and five WhatsApp text
messages. Control group participants received 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
receive tailored multichannel intervention lose significantly more weight
(Body Mass Index) compared with the control group. Secondary outcomes
include a health belief model.
