Contingency Management for Controlling Secondhand Smoke Exposures Among Asthmatic Children

The impact of continued cigarette usage is profoundly felt not only upon the primary smoker, but also among children where SHSe is linked with asthma exacerbations. Children with caregivers who are active smokers are more likely to utilize acute healthcare resources and miss more days of school due to asthma symptoms. Issues of pediatric smoke exposure are notably higher among low-income populations. This particular group has a greater amount of financial strain that increases their desire to cease smoking but is among the least successful at accomplishing this task. Aggressive marketing campaigns by cigarette companies have specifically targeted the urban poor but similar techniques by public health officials, though on a much diminished scale, have yet to completely counter the hold that this addictive product has on members of lower socioeconomic status. One approach that has demonstrated efficacy in reducing smoking in resistant populations emphasizes financial incentives. Incentives may provide a substitute for the gratification derived from nicotine if they are properly structured. This proposal applies a contingency management schema among caregivers of pediatric asthmatics and a member of their caregiver's social network - both of whom are likely major contributors to the child's total secondhand smoke exposure. A pilot two-arm randomized-control trial will be employed over a 6-month time interval.The study population will consist of the primary caregiver and a selected member of their social network, both of who are known active smokers, and contemplating smoking cessation; both individuals spend time (either indoors or outdoors) with the asthmatic child. We will recruit 50 caregiver-child-social network triads among a population of children diagnosed with uncontrolled, persistent asthma and routinely exposed to high levels of SHSe. Caregivers and members of their social network who are both active smokers will be randomized to receive standard smoking cessation strategies (n=25 triads) with or without financial incentives (n=25 triads). SHSe will be measured directly using salivary cotinine levels from children and home air nicotine levels. Caregiver and social network member smoking behaviors will be measured by nicotine biomarkers; both test results will be the basis for incentive payments. Asthma control will be evaluated using validated questionnaires and review of the participant's electronic health record.
