Brief Summary

Environmental tobacco smoke (ETS0, also known as secondhand smoke, is the combination of smoke given off by the burning end of a tobacco product and the smoke exhaled by the smoker. Children exposed to ETS are at an increased risk of sudden infant death syndrome (SIDS), ear infections, colds, pneumonia, bronchitis and more severe asthma. ETS can also slow the growth of children's lungs and can cause them to cough, wheeze and fell breathless. The purpose of this study is to determine the effectiveness of a motivational interviewing-based program in reducing ETS exposure and improving lung health among children who are enrolled in a Head Start program and whose households include a smoker.

Outcome Measures

Primary Outcomes (1)

  • Air Nicotine Levels

    Air nicotine levels were an indicator of child's exposure to environmental tobacco smoke (ETS)

    Measured at Baseline, 3, 6 and 12 months

Secondary Outcomes (4)

  • ETS Reduction, as Measured by Child's Cotinine Levels

    Measured at Baseline, 3, 6 and 12 months

  • Respiratory Function of Child by Self Report of Parent

    Measured at Baseline, 3, 6, and 12 months

  • Health Care Utilization by Child- Self Report From Parent/Caregiver

    Measured at baseline and 3, 6 and 12 months

  • Number of Participants Who Report Endorsing a Home Smoking Ban

    Measured at baseline, 3, 6 and 12 months

Study Arms (2)

Behavioral

EXPERIMENTAL

Motivational Interviewing Intervention Plus Education Caregivers will receive a home-based motivational interviewing intervention for ETS reduction plus an educational program for ETS reduction.

Behavioral: Motivational Interviewing Intervention for ETS Reduction

Education Only

ACTIVE COMPARATOR

Caregivers will receive only educational program for ETS reduction.

Behavioral: Educational Program for ETS Reduction

Interventions

The intervention is designed to motivate caregivers to reduce a child's ETS exposure by establishing a complete home and car smoking ban and by considering smoking cessation. Caregivers will receive 2 home visits \& 2 telephone session, both with a health counselor. Caregivers will be provided with feedback on air nicotine levels and child salivary cotinine levels. The main target for the intervention will be the primary caregiver of the child because the primary caregiver is ultimately responsible for protecting the child from ETS exposure. Any and all household members may participate in the intervention visits but are not required to do so.

Behavioral

An Environmental Protection Agency-based educational program that will consist of information about reducing tobacco smoke exposure.
