### Perspectives of mHealth in Obesity Control  
Healthcare providers recognize the potential of mHealth technologies to enhance obesity management by improving patient engagement, facilitating behavior change, and providing continuous support outside of clinical settings [18; 19; 21]. Those with positive outcomes from mHealth tools are more likely to adopt them, viewing them as complementary to traditional methods, offering remote monitoring and virtual support [70; 71]. However, some remain cautious due to concerns about increased workload, workflowdisruption, and the need for clinical evidence on their effectiveness and safety [14; 19; 76]. Overall, attitudes are increasingly positive as technology evolves and evidence accumulates, supporting wider adoption in clinical care. Individuals with obesity find mHealth tools convenient, offering accessible tracking, goal-setting, and support. These tools empower users through self-monitoring, behavior tracking, and personalized interventions, fostering autonomy and informed decision-making [20; 36; 63; 65]. Features like gamification, social support, and virtual coaching increase user engagement and adherence [10; 11; 18; 19; 20; 21; 22]. However, barriers such as technical challenges, privacy concerns, and usability issues need to be addressed to maximize effectiveness [30; 34; 46]. Stakeholders identify several barriers to the widespread use of mHealth for obesity control, including usability issues, data privacy concerns, and regulatory uncertainty [14; 16; 21; 23; 27]. Limited evidence on effectiveness and cost-effectiveness contributes to hesitancy, while the digital divide exacerbates health disparities, limiting access for underserved populations [23; 45; 46]. Integrating mHealth into existing healthcare systems requires overcoming logistical challenges such as resistance to change and insufficient provider training [61; 74; 76; 79; 80]. Perceptions of mHealth's effectiveness vary among stakeholders. Healthcare providers generally view mHealth as an effective complement to traditional methods [16; 24; 41; 45], while some patients prefer traditional approaches [22; 27]. Policymakers and insurers emphasize the need for evidence-based approaches to ensure efficacy and cost-effectiveness [23; 46; 81]. Researchers are key in evaluating mHealth, though the evidence base remains evolving [16; 18; 23; 24; 46]. Ethical concerns about data privacy, security, and informed consent are critical in mHealth applications for obesity control. Stakeholders advocate for robust data protection measures and transparency in data practices to build trust and ensure privacy [10; 18; 19; 23]. Fairness and equity in data collection are essential to address health disparities [13; 18; 19; 23]. Healthcare systems and policies must support the integration of mHealth into obesity management by developing clear regulatory frameworks, reimbursement policies, and clinical guidelines [46; 62; 67; 80; 81]. Interoperability among platforms and training for healthcare providers are also necessary to ensure effective adoption [20; 41; 80; 81]. Collaboration among policymakers, healthcare providers, technology developers, and patients is crucial to advancing mHealth integration. mHealth holds potential to reduce disparities in obesity treatment access by extending healthcare services to underserved populations, regardless of geographic or socioeconomic factors [61; 62; 81]. Tailoring tools to diverse needs enhances effectiveness, and the cost-effectiveness of mHealth compared to traditional interventions is a key advantage [19]. mHealth can support continuity of care by enabling communication across different care settings [69], further promoting self-management and improving outcomes for individuals with obesity. Innovations in mHealth for obesity control, such as personalized interventions, AI, wearable sensors, and remote monitoring, offer new opportunities to enhance behavior change and monitoring [7; 11; 13; 14].
