Abstract

OBJECTIVES:

This study tested the efficacy of coaching to reduce environmental tobacco smoke (ETS) exposure among asthmatic Latino children.

DESIGN:

After asthma management education, families were randomly assigned to no additional service (control condition) or to coaching for ETS exposure reduction (experimental condition).

SETTING:

The study was conducted in San Diego, California.

PARTICIPANTS:

Two hundred four Latino children (ages 3-17 years) with asthma participated.

INTERVENTION:

Approximately 1.5 hours of asthma management education was provided; experimental families also obtained 7 coaching sessions ( approximately 45 minutes each) to reduce ETS exposure.

OUTCOME MEASURES:

Reported ETS exposure and children's urine cotinine were measured.

RESULTS:

Parents in the coached condition reported their children exposed to significantly fewer cigarettes than parents of control children by 4 months (postcoaching). Reported prevalence of exposed children decreased to 52% for the coached families, but only to 69% for controls. By month 4, mean cotinine levels decreased among coached and increased among control children. Cotinine prevalence decreased from 54% to 40% among coached families, while it increased from 43% to 49% among controls. However, cotinine levels decreased among controls to the same level achieved by coached families by the 13-month follow-up.

CONCLUSIONS:

Asthma management education plus coaching can reduce ETS exposure more than expected from education alone, and decreases in the coached condition may be sustained for about a year. The delayed decrease in cotinine among controls is discussed.
