In 2001, an electronic medical record system was designed to collect data from smoking cessation services in France. By comparing two periods (2001-2003 and 2004-2006), this study assessed trends in the profile of smokers registered in the database.
A cross-sectional analysis on the 33,219 smokers registered in the database in 2001.
Sociodemographic details, psychological and medical history, and characteristics of tobacco consumption at baseline were examined.
The proportion of young smokers increased from 5.1% to 6.9%, and the proportion of underprivileged smokers increased from 9.3% to 10.9% between 2001-2003 and 2004-2006 (P<0.0001). The medical profile was unchanged, with about 37% of cases with tobacco-related diseases and 31% of cases with past depressive episodes in 2001-2003 and 2004-2006. The main finding was an increase in the mean concentration of carbon monoxide (CO) in expired air [from 18.8 parts per million (ppm) (SD 14.4) to 23.5 ppm (SD 14.1)], despite a decrease in the number of cigarettes smoked per day. The concentration of CO per cigarette also increased from 0.9 (SD 0.9) to 1.3 (SD 1.4).
As the number of cigarettes smoked per day decreased, the increase in mean concentration of CO per cigarette implies that increases in cigarette prices may have led to new smoking habits and/or compensatory smoking.
2001年，设计了一个电子病历系统来收集法国戒烟服务的数据。通过比较两个时期（2001 - 2003年和2004 - 2006年），本研究评估了数据库中登记的吸烟者概况的趋势。
对2001年数据库中登记的33219名吸烟者进行横断面分析。
检查了社会人口统计学细节、心理和病史以及基线时的烟草消费特征。
2001 - 2003年至2004 - 2006年期间，年轻吸烟者的比例从5.1%增加到6.9%，贫困吸烟者的比例从9.3%增加到10.9%（P<0.0001）。医疗概况没有变化，2001 - 2003年和2004 - 2006年约37%的病例患有与烟草相关的疾病，31%的病例有过去的抑郁发作史。主要发现是呼出气体中一氧化碳（CO）的平均浓度增加[从百万分之18.8（ppm）（标准差14.4）增加到23.5 ppm（标准差14.1）]，尽管每天吸烟的数量减少。每支香烟的CO浓度也从0.9（标准差0.9）增加到1.3（标准差1.4）。
随着每天吸烟数量的减少，每支香烟CO平均浓度的增加意味着香烟价格的上涨可能导致了新的吸烟习惯和/或代偿性吸烟。
