Mobile Health Interventions for Pediatric Obesity Management

Mobile health (mHealth) interventions harness smartphones, tablets and text messaging to support the prevention and management of obesity in children and adolescents. These approaches encompass a range of digital tools, including apps for self-monitoring dietary intake and physical activity, chatbots for tailored nutritional education, gamified platforms to enhance engagement, and parent-oriented programmes that deliver real-time feedback and goal-setting prompts. Many interventions integrate behaviour change techniques such as self-monitoring, personalised feedback, social support networks and motivational incentives to foster sustained engagement. Parental involvement and culturally adapted content are key to reaching younger age groups, while integration into primary care pathways and schools can enhance scalability. Despite promising short-term improvements in dietary habits, screen time and moderate-vigorous activity, evidence for sustained reductions in body mass index (BMI) or BMI z-score remains mixed. Ongoing challenges include maintaining user adherence, tailoring content to diverse populations, ensuring data privacy and securing robust, long-term clinical outcomes. The global rise in smartphone penetration offers unprecedented opportunities to deliver cost-effective, scalable interventions for paediatric obesity management, although rigorous evaluation of effectiveness and implementation strategies is essential to inform policy and practice.

Technical terms

mHealth: Delivery of health services and information via mobile devices to support monitoring, education and behaviour change.

BMI z-score: A standardised measure of a child’s body mass index relative to age- and sex-matched population norms.

Behaviour change technique (BCT): A discrete, evidence-based method used to alter health behaviours, such as goal-setting or self-monitoring.

Self-monitoring: The regular tracking of one’s own behaviours (for example, dietary intake or physical activity) to increase awareness and facilitate change.

Gamification: The incorporation of game-like elements—points, levels or challenges—into interventions to boost user motivation and engagement.
