The chance to earn shopping vouchers offered with a smoking cessation program was a bigger motivator for inner-city pregnant women to quit smoking than was the free quit-smoking program alone (Tappin D et al. BMJ. doi:10.1136/bmj.h134 [published online January 27, 2015]).
A phase 2 superiority trial in Glasgow, Scotland, assigned 306 pregnant women to routine smoking cessation services in addition to offering up to £400 (about $614) of financial incentives: £50 for meeting with a smoking cessation counselor and setting a quit date, £50 for smoking abstinence 4 weeks after the quit date (confirmed by a carbon monoxide breath test), £100 for not smoking after 12 weeks, and a final £200 voucher for abstinence at 34 to 38 weeks’ gestation, verified by cotinine in saliva or urine. The other 303 pregnant women were offered routine smoking cessation services alone. All participants who reported quitting had their smoking status confirmed by cotinine levels in saliva and urine in later pregnancy.
