<b>OBJECTIVES: </b>To examine the effects of partnering and parenting transitions on smoking continuity in young adults.
</p>

<p>
<b>METHODS: </b>A prospective cohort study was conducted involving 1084 young smokers and former smokers who completed questionnaires at baseline (2004-2006, aged 26-36&nbsp;years) and 5&nbsp;years later.
</p>

<p>
<b>RESULTS: </b>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.
</p>

<p>
<b>CONCLUSIONS: </b>The benefits of partnering were greater for men than women and transition into parenthood was of greater benefit to women.
