Effectiveness of Mobile Health Applications for Cardiometabolic Risk Reduction in Urban and Rural India: A Pilot,...

Area of Science:

• Digital Health
• Cardiometabolic Health
• Public Health Interventions

Background:

• Limited data exists on mHealth effectiveness for cardiometabolic risk factors.
• Personalized healthcare delivery via mHealth technology shows potential.
• High prevalence of diabetes risk in South Asian populations necessitates innovative solutions.

Purpose of the Study:

• To assess the effectiveness of mobile health applications (apps) in reducing cardiometabolic risk factors.
• To evaluate mHealth app efficacy in adults aged 25-60 years in urban and rural India.
• To investigate impacts on weight, blood pressure, and lifestyle behaviors.

Main Methods:

• Pilot randomized controlled trial conducted in Tamil Nadu, India.
• Recruited smartphone users (25-60 years) at high risk for diabetes.
• Evaluated four mHealth apps for cardiometabolic risk reduction; analyzed weight loss using intention-to-treat analysis.

Main Results:

• Significant body weight reduction observed in the intervention group (-2.40 kg urban, -1.19 kg rural).
• Improvements noted in body mass index, waist circumference, blood pressure, and fasting blood sugar (FBS).
• Positive changes in dietary and physical activity behaviors were reported compared to controls.

Conclusions:

• mHealth interventions demonstrate efficacy in reducing diabetes risk.
• Mobile health apps can significantly improve cardiometabolic health markers.
• Interventions positively influenced lifestyle behaviors in South Asian populations.
