Abstract

This study aims to assess the effectiveness of mobile health (Health) applications in facilitating a 5% reduction in body weight among obese and overweight adults. Obesity and overweight conditions pose significant health risks, including cardiovascular diseases, type 2 diabetes, and other metabolic disorders. Traditional weight loss interventions often face challenges such as limited accessibility, adherence issues, and high costs. In contrast, Health applications offer a promising solution by providing convenient, accessible, and cost-effective tools for weight management. The study employs a randomized controlled trial design, enrolling obese and overweight adults aged 18-65 years. Participants are randomly assigned to either the intervention group, which utilizes a designated Health application for weight management, or the control group, which receives standard care or alternative interventions. The Health application incorporates features such as personalized dietary recommendations, physical activity tracking, behavior modification strategies, social support networks, and progress monitoring.

Primary outcomes include changes in body weight, body mass index (BMI), waist circumference, and other relevant anthropometric measures. Secondary outcomes comprise improvements in dietary habits, physical activity levels, self-efficacy, and quality of life. Data collection involves baseline assessments followed by periodic followups over a predetermined intervention period. Statistical analyses will compare outcomes between the intervention and control groups, utilizing appropriate methods such as t-tests, chi-square tests, or regression analyses. Subgroup analyses may explore factors influencing intervention effectiveness, such as age, gender, baseline BMI, and adherence levels. Additionally, process evaluation components assess user engagement, satisfaction, and usability of the Health application. Findings from this study will contribute valuable insights into the effectiveness and feasibility of Health applications as a tool for promoting weight loss among obese and overweight adults. Results will inform healthcare providers, policymakers, and stakeholders in optimizing interventions for combating the global obesity epidemic and improving public health outcomes.
