研究人员调查了提供经济激励措施帮助怀孕吸烟者戒烟的有效性。进行了一项随机对照试验。该干预措施包括常规护理加上高达400英镑（559欧元; 600美元）的奖励，奖励参加专业怀孕戒烟服务并在妊娠34 - 38周戒烟的女性。对照组只接受常规护理，包括面对面讨论吸烟和戒烟，免费尼古丁替代疗法和每周支持电话。背景是苏格兰西部物质匮乏的内城人口。参与者是612名自报怀孕吸烟者，年龄至少16岁，怀孕不到24周。妇女被随机分配到干预组（n = 306）或对照组（n = 306）。随后，分配到对照组的3名妇女撤回了同意，包括同意使用收集的任何数据，从而导致用于主要结局分析的样本量为303。
主要结局是妊娠34 - 38周时戒烟。在妊娠34-38周时戒烟的吸烟者比例，经济奖励组显著高于对照组（22.55%（n = 69）vs8.58%（n = 26），绝对危险度差13.97%;相对危险度2.63，95%可信区间1.73~4.01，P <0.001）。研究人员得出结论，经济激励措施可以有效帮助怀孕吸烟者戒烟。

Researchers investigated the effectiveness of offering financial incentives in helping pregnant smokers to quit. A randomised controlled trial was performed. The intervention consisted of routine care plus incentives of up to £400 (€559; $600) for women who attended specialist pregnancy stop smoking services and were abstinent from smoking at 34-38 weeks’ gestation. The control group received routine care only, which included offers of face to face appointments to discuss smoking and cessation, free nicotine replacement therapy, and weekly support phone calls. The setting was a materially deprived inner city population in the west of Scotland. Participants were 612 self reported pregnant smokers aged at least 16 years who were less than 24 weeks pregnant. Women were randomised to the intervention (n=306) or control (n=306). Consent, including consent to use any data collected, was subsequently withdrawn by three women allocated to the control group, resulting in a sample size of 303 for analysis of the primary outcome.1
The primary outcome was abstinence from smoking at 34-38 weeks’ gestation. The percentage of smokers who were abstinent at 34-38 weeks’ gestation was significantly higher in the financial incentives group than in the control group (22.55% (n=69) v 8.58% (n=26), absolute risk difference 13.97%; relative risk 2.63, 95% confidence interval 1.73 to 4.01; P<0.001). The researchers concluded that financial incentives were effective in helping pregnant smokers quit.
