The WHO estimates that half the children in the world are exposed to secondhand smoke. Despite recent smoke free legislation across the country, an estimated 22 percent of children are still exposed in their home environments. These children have increased rates of lower respiratory illnesses, middle ear effusion, asthma, reduced lung function and SIDS. This study aims to evaluate the effectiveness of using a structured tobacco cessation education program, CEASE (Clinical Effort against Secondhand Smoke Exposure), delivered by pediatric residents in the outpatient continuity clinic of a pediatric residency program in reducing the exposure of infants to secondhand smoke. It will also evaluate the efficacy of using a secondhand smoke biomarker, urine cotinine level measurement and feedback as an adjunct to counseling.
