The aim of this study was to survey pregnant smokers' interest in different types of smoking cessation support. Interest in cessation support was assessed via telephone interviews with women identified as smokers at their first antenatal visit. Of 206 pregnant smokers interviewed, 87% (179/206) reported wanting to stop smoking, of whom 69% (124/179) expressed an interest in receiving help with stopping. Interest was highest for behavioural support (82%, 102/124) and self-help materials (77%, 95/124). There was a significant preference for individual versus group appointments, for 'buddying' among those not in professional/managerial occupations versus those in professional/managerial occupations, and for behavioural support among non-Caucasians versus Caucasians. These findings highlight the high level of interest expressed in support with stopping smoking among pregnant smokers. Smoking cessation services may benefit through offering a range of interventions for pregnant smokers, through considering ethnic and occupational status, and through routinely offering individual appointments.
