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 mess..., Study design: Randomized controlled trial

## Description of the data and file structure

Dataset Title: Weight Management Intervention Study – Baseline, 2-Month, and 5-Month Follow-Up Data

## 1. General Description

This dataset contains participant-level data from a weight management intervention study conducted among university students. Data were collected at three time points:

* Baseline (pre-intervention)
* 2 months post-intervention
* 5 months post-intervention

The dataset includes demographic characteristics, anthropometric measures, and questionnaire-based variables derived from health belief model constructs, self-efficacy scales, and behavioral assessments related to diet and physical activity.

All data are anonymized. Participants are identified only by unique study codes.

## 2. File Structure

The datas..., All data included in this dataset was collected in accordance with applicable ethical standards for research involving human participants. Prior to data collection, ethical approval was obtained from the appropriate institutional review board (IRB), and all participants provided informed consent to participate in the study. As part of the consent process, participants were explicitly informed that their data may be shared in a fully de-identified form for research and publication purposes, including deposition in a public data repository.
To ensure participant privacy and confidentiality, the dataset has been thoroughly de-identified prior to submission. All direct identifiers have been removed, including names, student identification numbers, contact information, and any other uniquely identifying personal details. Indirect identifiers that could potentially enable re-identification (such as highly specific demographic or contextual variables) have been carefully reviewed and either ge...,
