Barriers and enablers to implementing a smoke-free home and car during pregnancy: a qualitative study among expectant Israeli fathers.

Secondhand smoke exposure during pregnancy is a significant cause of negative health effects. Interventions among expectant fathers that focus on creating a smoke-free home and car may be effective because pregnancy has been identified as a "window of opportunity" that generates a strong motivation and creates a sense of urgency to change smoking behavior, while being considered more achievable than smoking cessation. Interventions might be effective if they focus on strengthening the parental responsibility among expectant fathers and emphasize the benefits of a smoke-free home and car, while maintaining male autonomy and increasing skills to effectively implement a smoke-free home and car.
