In July 2007, legislation banning smoking in public places was introduced in England. This study investigates the impact of this legislation on smoking in Bury.
A postal survey was undertaken before the implementation of the legislation. The survey was repeated 3 months after the smoking ban. Smoking prevalence was then compared. Participants were randomly selected using the PCT database of people registered with general practitioners. In the baseline and second survey, 3500 questionnaires were sent to participants. In the baseline survey 59.5% responded. In the second survey 56.3% responded.
Results were standardized to age and gender bands from Bury's population. The baseline survey found that the standardized prevalence of smoking before the ban was 22.4% and after it was 22.6%. The proportion of smokers reporting that on average they smoked 20 cigarettes a day or greater fell from 27.6 to 21.8% (P = 0.044).
The study found that in Bury the smoking ban did not have a substantial impact on smoking prevalence but had an impact on the proportion of heavy smokers. The measurement of smoking prevalence before the change in legislation can be used to assess its long-term impact on smoking habits in Bury.
2007年7月，英国出台了在公共场所禁烟的法律。本研究调查了该法律对伯里地区吸烟情况的影响。
在该法律实施前进行了一次邮寄调查。在禁烟令实施3个月后重复进行了该调查。然后比较吸烟率。使用全科医生注册人员的初级保健信托数据库随机选择参与者。在基线调查和第二次调查中，向参与者发送了3500份问卷。在基线调查中，59.5%的问卷得到回复。在第二次调查中，56.3%的问卷得到回复。
结果根据伯里地区人口的年龄和性别分组进行了标准化。基线调查发现，禁烟前的标准化吸烟率为22.4%，禁烟后为22.6%。报告平均每天吸烟20支及以上的吸烟者比例从27.6%降至21.8%（P = 0.044）。
该研究发现，在伯里地区，禁烟令对吸烟率没有重大影响，但对重度吸烟者的比例有影响。在立法变更前对吸烟率的测量可用于评估其对伯里地区吸烟习惯的长期影响。
