Older smokers are often not encouraged to quit smoking due to the erroneous idea that it is too late for such interventions.
To compare smoking cessation rates among older and younger treatment seekers, and to evaluate whether age is an obstacle to smoking cessation.
Smokers (n = 987) were submitted to the same behavioural programme plus pharmacotherapy at the Smoking Cessation Clinic of Hospital Sao Lucas, in Porto Alegre, Brazil, from July 2004 to June 2009. Quit rates were evaluated at 2, 6 and 12 months. Abstinence was confirmed by exhaled carbon monoxide < 10 ppm. Volunteers were grouped by age <60 and ≥ 60 years.
Abstinence rates (± SD) in the younger group were respectively 57.1% (± 1.9), 46.8% (± 2.1) and 43.5% (± 2.7) at 2, 6 and 12 months of follow-up. Rates for the ≥ 60 year group were respectively 67.4% (± 4.3), 52.3% (± 5.4) and 53.3% (± 5.4; log rank test, P = 0.073). The difference was also not statistically significant using Cox regression (adjusted HR 0.90, 95%CI 0.66-1.22, P = 0.48).
In this real-world setting, treatment for smoking cessation led to similar abstinence rates in older and younger smokers. These results may have implications for clinical practice and smoking cessation policies for low- and middle-income countries such as Brazil.
由于存在这种错误观念，即对于此类干预措施来说已经为时过晚，因此往往不鼓励老年吸烟者戒烟。
比较老年和年轻治疗寻求者的戒烟率，并评估年龄是否是戒烟的障碍。
2004 年 7 月至 2009 年 6 月，巴西阿雷格里港圣卢卡斯医院的戒烟诊所将吸烟者（n=987）纳入相同的行为方案加药物治疗。在 2、6 和 12 个月时评估戒烟率。通过呼气一氧化碳<10 ppm 来确认是否戒烟。志愿者根据年龄<60 岁和≥60 岁进行分组。
年轻组在 2、6 和 12 个月随访时的戒烟率（± SD）分别为 57.1%（±1.9）、46.8%（±2.1）和 43.5%（±2.7）。≥60 岁组的相应戒烟率分别为 67.4%（±4.3）、52.3%（±5.4）和 53.3%（±5.4；对数秩检验，P=0.073）。使用 Cox 回归分析时，差异也无统计学意义（调整后的 HR 0.90，95%CI 0.66-1.22，P=0.48）。
在这种现实环境中，戒烟治疗在老年和年轻吸烟者中导致了相似的戒烟率。这些结果可能对巴西等中低收入国家的临床实践和戒烟政策具有意义。
