Chest
Clinical Investigations: AsthmaReduction of Environmental Tobacco Smoke Exposure in Asthmatic Children: A 2-Year Follow-up
Section snippets
Design
Original Study: A three-group repeated measures design was employed in the initial study. Ninety-one families with at least one parent who smoked cigarettes and a child (6 to 17 years) with asthma who was exposed to at least one of the parent's cigarettes per day were recruited from among patients at four of the largest pediatric allergy medical centers in San Diego. Screening forms obtained from the medical centers were reviewed and eligible families were invited to participate in a study of
RESULTS
The counseling group included an outlying data point at baseline (25 cigarettes per day), and the control group included two outliers at baseline (30 and 40 cigarettes per day). Distributions of the exposure variables were moderately skewed at most measurement points. Outlying cases were retained in the data set, and dependent variables for all analyses were transformed using natural logarithms (after adding a value of 1 to all scores to remove zero values). Means of these logs of target
DISCUSSION
These ETS data demonstrate an initial reactivity among participants in all groups, followed by a greater decrease in exposure in the counseling group. This was followed by stabilization or slight increase for the control subjects and sustained or slightly decreased exposure for the counseling group, but general stability during the 6- to 12-month initial follow-up period. The overall effect was maintained throughout the entire 30-month period even in the context of the observed change

Randomized Trial to Reduce Air Particle Levels in Homes of Smokers and Children
2018, American Journal of Preventive MedicineCitation Excerpt :Up to $50 total (for all coaching sessions) was added with IRB approval, when it became clear that four coaching visits were difficult to complete. Coaching was guided by previous SHS reduction research and the Behavioral Ecological Model, with emphasis on reducing particle concentrations in the home, while targeting reductions in SHS-related particles specifically.24,32–34 The coaching emphasized the protection of children from SHS exposure in the home and did not require smoking cessation.
Prenatal Versus Postnatal Tobacco Smoke Exposure and Intensive Care Use in Children Hospitalized With Bronchiolitis
2016, Academic PediatricsCitation Excerpt :In a variety of clinical settings, the effectiveness of parental education and counseling programs on reducing children's TSE was not clearly demonstrated.21 However, among studies of parents of children with respiratory illnesses, 4 of 13 studies showed significant effects on child health outcomes22,23 and/or smoking cessation.24,25 Studies that showed efficacy primarily used intensive counseling or motivational interviewing methods, which may hold the greatest potential for reducing the morbidity associated with TSE in children.
Providing coaching and cotinine results to preteens to reduce their secondhand smoke exposure: A randomized trial
2011, ChestCitation Excerpt :Families assigned to the control group were unaware of specific coaching procedures and continued in the study with measurement visits and cohort retention phone calls only. Individualized coaching (analogous to athletic coaching) and cotinine feedback for SHSe reduction were guided by previous research21–23 and the Behavioral Ecological Model,25,26 with emphasis on reinforcing change in adolescents' avoidance of SHSe. TCs in the coaching group were told that the goal was to help them reduce/eliminate their SHSe.
Sensitivity to secondhand smoke exposure predicts smoking susceptibility in 8-13-year-old never smokers
2011, Journal of Adolescent HealthCitation Excerpt :Combined with evidence of possible desensitization to SHSe over time, and differences in sensitivity as a function of parent education and racial/ethnic background, these results suggest that the children and preteens under 12 years may be an ideal time for targeted prevention strategies, including educating parents about the harmful effects of SHSe on their children and counseling them to assist in reducing the child's exposure to SHS [36–40].
