Moderators of the association between regular smoking exposure and motivation and attempts to quit: a repeat cross-sectional study.
Abstract
AIMS: To estimate the associations between regular exposure to smoking by other people and motivation and attempts to quit among current smokers. To examine whether socio-demographic and other factors moderate these associations. DESIGN: A repeat nationally representative cross-sectional survey. Data were collected monthly between November 2014 and February 2019. SETTING: England. PARTICIPANTS: Current smokers aged ≥ 16 years from the Smoking Toolkit Study (N=15,136). MEASUREMENTS: Participants were asked whether other people regularly smoke in their presence, how motivated they were to quit, and whether they had made a quit attempt in the past year. Moderators assessed were occupation-based social grade, housing tenure, urges to smoke, high-risk alcohol consumption, and disability. Adjusted analyses included moderators, socio-demographic (age/sex/ethnicity/sexual orientation/marital status/children in household) and seasonal (quarter/year) confounders. FINDINGS: Current smokers who were regularly exposed to other people smoking in their presence were less likely to be highly motivated to quit (odds ratio = 0.88 [95%CI 0.80-0.97]), but were no less likely to have made a quit attempt in the past year (OR 1.04 [0.97-1.13], Bayes Factor (BF) = 0.05). The inverse relationship between regular smoking exposure and motivation to quit was moderated by urges to smoke, such that exposure was only associated with a reduction in motivation among those without strong urges to smoke (OR 0.83 [0.75-0.93] versus OR 1.04 [0.86-1.26]; p = .048). None of the other factors significantly moderated the association with motivation to quit, and none moderated the relationship between regular smoking exposure and quit attempts. All non-significant interactions, except social grade (BF = 1.44) with quit attempts, had Bayes Factors that supported the hypothesis of no moderation (BF range: 0.12-0.21). CONCLUSIONS: Among current smokers in England, regular exposure to other smokers appears to be associated with lower motivation to quit in people without strong urges to smoke, yet there appears to be no association with quit attempts in the previous year. Social grade, housing tenure, high-risk alcohol consumption and disability do not moderate these associations.
