ABSTRACT
OBJECTIVES:
Exposing children to secondhand tobacco smoke (SHS) causes significant harm and occurs predominantly through smoking by caregivers in the family home. We report a trial of a complex intervention designed to reduce secondhand smoke exposure of children whose primary caregiver feels unable or unwilling to quit smoking.DESIGN:
An open-label, parallel, randomised controlled trial.SETTING:
Deprived communities in Nottingham City and County, EnglandPARTICIPANTS:
Caregivers resident in Nottingham City and County in England who were at least 18 years old, the main caregiver of a child aged under 5 years living in their household, and reported that they were smoking tobacco inside their home.INTERVENTIONS:
We compared a complex intervention combining personalised feedback on home air quality, behavioural support and nicotine replacement therapy for temporary abstinence with usual care. MAINOUTCOMES:
The primary outcome was change in air quality in the home, measured as average 16-24 hours levels of particulate matter of < 2.5 µm diameter (PM2.5), between baseline and 12 weeks. Secondary outcomes included changes in maximum PM2.5, proportion of time PM2.5 exceeded WHO recommended levels of maximum exposure of 25 µg/mg3, child salivary cotinine, caregivers' cigarette consumption, nicotine dependence, determination to stop smoking, quit attempts and quitting altogether during the intervention.RESULTS:
Arithmetic mean PM2.5 decreased significantly more (by 35.2 %; 95% CI 12.7% to 51.9 %) in intervention than in usual care households, as did the proportion of time PM2.5 exceeded 25 µg/mg3, child salivary cotinine concentrations, caregivers' cigarette consumption in the home, nicotine dependence, determination to quit and likelihood of having made a quit attempt.CONCLUSIONS:
By reducing exposure to SHS in the homes of children who live with smokers unable or unwilling to quit, this intervention offers huge potential to reduce children's' tobacco-related harm. TRIAL REGISTRATION NUMBER ISRCTN81701383.This trial was funded by the UK National Institute for Health Research (NIHR) RP-PG-0608-10020.Palavras-chave
