Utilizing Biomarker Feedback Documenting Child Exposure to Tobacco Toxins to Promote Smoke-Free Homes: Study Protocol for a Randomized Clinical Trial
ABSTRACT
Background:
Background:
Exposure to second-hand smoke (SHS) early in life increases the risk of SIDS, asthma and respiratory illnesses. Since children’s primary exposure to SHS occurs in the home, these most vulnerable members of our society are not fully protected by recent increases in the adoption of smoking bans in public spaces. Although exposure to SHS is a readily addressed cause of excess morbidity, few low-income homes strictly enforce smoking restrictions.
Objective:
Objective:
To test a novel approach to motivate the adoption of home smoking restrictions (HSR) and to eliminate child SHS exposure by providing parents with objective, biomarker documentation of child exposure to tobacco toxins.
Methods:
Methods:
From 2011 to 2013, 195 low-income, female smokers with children ≤ 10 years old, residing in their homes were recruited into a two-arm randomized clinical trial. Participants were assigned to one of two groups: Biomarker Feedback (n = 98) vs. Health Education, (n = 97). In-home assessments were administered at baseline, week 16 and week 26. Child urine nicotine, cotinine and NNAL (a metabolite of the known tobacco carcinogen, NNK), an objective measure of home SHS exposure (i.e., passive nicotine dosimeter) and a surface sample of residual (ie, third-hand) tobacco smoke were collected at all three time points. Primary outcome was dosimeter-verified, complete home smoking restrictions at 6-months post-randomization. Secondary outcomes included parental self report of smoking behavior change and child urine biomarker change.
Results:
Results : Data collection and analyses are complete and results are being interpreted.
Conclusions:
Discussion: The study protocol describes the development of a novel community-based controlled trial designed to examine the efficacy of biomarker feedback documenting a child’s exposure to enviornmental tobacco smoke on parental smoking behavior change.
