National social marketing campaigns have been shown to promote smoking cessation in England. There is reason to believe that regional and city-wide campaigns can play a valuable role in reducing smoking prevalence over and above any national tobacco control activity. This study aimed to assess the impact of the London Smoking Cessation Transformation Programme, a multi-component citywide smoking cessation programme, on quit attempts and quit success rates.
Interrupted time-series analyses, using Autoregressive Integrated Moving Average (ARIMA) and generalized additive models (GAM) of population trends in the difference between monthly quit attempts and quit success rates among smokers who made a quit attempt in London versus the rest of England before and during the first year of the programme.
A total of 55 528 past-year adult smokers who participated in a monthly series of nationally representative cross-sectional surveys in England between November 2006 and August 2018. Twelve and a half per cent of smokers lived in London (intervention region) and 87.5% lived in the rest of England (control region).
Monthly prevalence of quit attempts and quit success rates among smokers who made a quit attempt.
The monthly difference in prevalence of quit attempts in London compared with the rest of England increased by 9.59% [95% confidence interval (CI) = 4.35-14.83, P < 0.001] from a mean of 0.04% pre-intervention to 9.63% post-intervention. The observed increase in success rates among those who tried was not statistically significant (B = 4.72; 95% CI = -2.68 to 12.11, P = 0.21); Bayes factors indicated that these data were insensitive. GAM analyses confirmed these results.
The promotion of the London Smoking Cessation Transformation Programme during September 2017 was associated with a significant increase in quit attempts compared with the rest of England. The results were inconclusive regarding an effect on quit success among those who tried.
国家社会营销活动已被证明可促进英格兰的戒烟。有理由相信，区域和全市范围的运动可以在减少吸烟率方面发挥宝贵作用，超出任何国家烟草控制活动的作用。本研究旨在评估伦敦戒烟转型计划（一项多组成分的全市戒烟计划）对戒烟尝试和戒烟成功率的影响。
使用自回归综合移动平均（ARIMA）和人口趋势的广义加性模型（GAM）进行中断时间序列分析，比较在计划实施之前和第一年期间，伦敦吸烟者戒烟尝试和戒烟成功率与英格兰其他地区吸烟者之间每月戒烟尝试和戒烟成功率之间的差异。
共有 55528 名过去一年的成年吸烟者参加了 2006 年 11 月至 2018 年 8 月期间在英格兰进行的一系列全国代表性横断面调查。12.5%的吸烟者居住在伦敦（干预地区），87.5%居住在英格兰其他地区（控制地区）。
每月尝试戒烟的吸烟者戒烟尝试和戒烟成功率的流行率。
与英格兰其他地区相比，伦敦的戒烟尝试每月差异增加了 9.59%（95%置信区间 [CI] = 4.35-14.83，P < 0.001），从干预前的平均 0.04%增加到干预后的 9.63%。尝试戒烟者的成功率增加不具有统计学意义（B = 4.72；95%CI = -2.68 至 12.11，P = 0.21）；贝叶斯因子表明这些数据不敏感。GAM 分析证实了这些结果。
与英格兰其他地区相比，2017 年 9 月期间推广伦敦戒烟转型计划与戒烟尝试显著增加有关。对于尝试戒烟者的戒烟成功率是否有影响，结果尚无定论。
