What this trial studies

This intervention aims to reduce secondhand tobacco smoke exposure in homes by implementing an evidence-based program designed for families with children. The study utilizes a cluster randomized controlled trial design, enrolling 416 participants from households in the Metropolitan Area of Barcelona, where at least one adult smokes and smoking is permitted indoors. The intervention follows a structured five-step approach to encourage families to establish smoke-free environments. Participants are recruited through local student family associations, ensuring a community-focused approach to public health.

Who should consider this trial

Good fit: Ideal candidates are families with children under 18 years old where at least one adult is a smoker and allows smoking in the home.

Not a fit: Patients who do not have children or do not live with a smoker will not benefit from this intervention.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce secondhand smoke exposure among children, leading to improved health outcomes.

How similar studies have performed: Previous studies have shown success with similar smoke-free home interventions, indicating a promising approach to reducing secondhand smoke exposure.
