Virtual Education Protocol for Sustainable Lifestyle Modifications

Family-based digital interventions have been shown to be effective in helping children and families adopt healthier lifestyles. This study aims to assess the efficacy of virtual educational programs in promoting lifestyle modification, with a focus on improving dietary habits, increasing physical activity, and reducing tobacco use among families in Isfahan, Iran.

This study was carried out in two stages from 2023 to 2024. The initial phase involved a comprehensive review of the existing literature, alongside consultations with health experts, to standardize and develop intervention programs tailored to the cultural context of Iranian society. The second phase was a randomized intervention survey conducted in parallel and double-blind (participants and statistics specialist) manner in two groups. Eligible participants included families registered at health centers, with at least one child aged 6-15 years and access to the internet and electronic devices. Participants were randomly assigned to either the intervention or control group. In the intervention group, each family member received virtual educational content via a website or mobile app. The program was delivered weekly for the first 8 weeks, followed by biweekly sessions for the next 8 weeks. The content focused on improving dietary habits, increasing physical activity, and reducing tobacco use and smoking exposure. The control group received no educational interventions but was given access to the recorded sessions after the study concluded. Participants were followed up at 2- and 6-month post-intervention.

The primary outcomes include changes in body mass index (BMI), physical activity levels in both children and parents, dietary habits, smoking status, and exposure to indoor air pollutants. Conclusions: The rigorous design, incorporating cultural adaptation and a double-blind randomized controlled trial with follow-up assessments, provides a strong methodological framework for evaluating the effectiveness of virtual health interventions in a specific cultural context.
