What this trial studies
This randomized trial tests a combined approach in real-world pediatric clinics to help parents quit smoking and address unmet social needs using a health navigator. Eligible participants are parents or guardians of children under 18 with at least one social risk, recruited from two Montreal-area centers. Participants are randomized to receive a structured smoking cessation intervention plus health navigation to resolve social barriers, versus usual care. The study aims to measure quit rates and changes in child secondhand smoke exposure, alongside engagement with social services. Enrollment targets 1,000 participants over 2.5 years.
Why it matters
Potential benefit: If successful, the program could improve child health by reducing secondhand smoke exposure and helping families access social supports.
How similar studies have gone: Prior work shows mixed success with integrated behavioral and social support approaches; this trial tests a combined strategy in a real-world setting.
