We compared smoking initiation and cessation in Quebec versus the rest of Canada as possible underpinnings of the continued higher cigarette smoking prevalence in Quebec.
Data were drawn from the Canadian Community Health Survey (CCHS). We compared average and sex-stratified prevalence estimates of (1) current cigarette smoking in persons aged 15 years and older; (2) past-year initiation of cigarette smoking in those aged 12 to 17 and 18 to 24 years; and (3) past-year cessation in adults aged 25 years and older in Quebec versus the other nine Canadian provinces in each two-year CCHS cycle from 2007/08 to 2017/18.
The prevalence of current smoking decreased from 25% to 18% among adults aged 15 years and older in Quebec from 2007/08 to 2017/18, and from 22% to 16% in the rest of Canada. Initiation among those aged 12 to 17 years decreased from 9% to 5% in Quebec, and from 7% to 3% in the rest of Canada. Neither initiation among people aged 18 to 24 (at 6% and 7%, respectively) nor cessation among adults aged 25 and older (approximately 8%) changed over time in Quebec or in the rest of Canada. In each two-year CCHS cycle, past-year initiation among those 12 to 17 years of age was consistently higher in Quebec than in the rest of Canada, but there were no substantial or sustained differences in initiation among people aged 18 to 24 or in past-year cessation. Findings were similar when stratified by sex.
Higher levels of smoking initiation among youth aged 12 to 17 years could be a proximal underpinning of the continuing higher prevalence of smoking in Quebec versus the rest of Canada.
我们比较了魁北克省和加拿大其他地区的吸烟起始和戒烟情况，以了解为什么魁北克省的香烟吸烟率持续居高不下。
数据来自加拿大社区健康调查（CCHS）。我们比较了 2007/08 至 2017/18 年每两年一次的 CCHS 周期中，魁北克省和加拿大其他九个省份 15 岁及以上人群中（1）当前吸烟的平均和性别分层流行率估计值；（2）12 至 17 岁和 18 至 24 岁人群中过去一年的吸烟起始率；（3）25 岁及以上成年人过去一年的戒烟率。
从 2007/08 年到 2017/18 年，魁北克省 15 岁及以上成年人的当前吸烟率从 25%降至 18%，而加拿大其他地区则从 22%降至 16%。12 至 17 岁人群的起始率从 9%降至 5%，加拿大其他地区则从 7%降至 3%。18 至 24 岁人群的起始率（分别为 6%和 7%）和 25 岁及以上成年人的戒烟率（约 8%）在魁北克或加拿大其他地区均未随时间变化。在每个两年一次的 CCHS 周期中，12 至 17 岁人群的过去一年起始率在魁北克省一直高于加拿大其他地区，但在 18 至 24 岁人群或过去一年戒烟率方面，并没有实质性或持续的差异。按性别分层的结果相似。
12 至 17 岁青少年吸烟起始率较高可能是魁北克省与加拿大其他地区相比，吸烟率持续居高不下的一个近因。
