Partnering and parenting transitions associate with changing smoking status: a cohort study in young Australians
To examine the effects of partnering and parenting transitions on smoking continuity in young adults.
A prospective cohort study was conducted involving 1084 young smokers and former smokers who completed questionnaires at baseline (2004–2006, aged 26–36 years) and 5 years later.
233/570 (40.9%) smokers quit and 58/514 (11.3%) former smokers resumed smoking during follow-up. For partnering transitions, compared with remaining not partnered, the likelihood of quitting was higher among men who became (RR 2.84 95% CI 1.62, 4.98) or stayed (RR 2.12, 95% CI 1.18, 3.80) partnered and women who became partnered (RR 1.50, 95% CI 1.03, 2.18). People who became (RR 0.14, 95% CI 0.03, 0.58) or stayed (RR 0.51, 95% CI 0.27, 0.95) partnered had a lower risk of resuming smoking than their continuously not partnered peers. For parenting transitions, having a first child born increased women’s probability of quitting smoking relative to remaining childless (RR 1.74, 95% CI 1.30, 2.33), while having additional children did not.
The benefits of partnering were greater for men than women and transition into parenthood was of greater benefit to women.
