To determine the prevalence of smoking and the frequency of smoking cessation counseling among patients at a university hospital, as well as to compare smokers and former smokers in terms of smoking history.
A cross-sectional study involving 629 patients at the Federal University of Paraná Hospital de Clínicas, located in the city of Curitiba, Brazil.
Of the 629 patients, 206 (32.7%) were male, 76 (12.1%) were smokers, 179 (28.5%) were former smokers, and 374 (59.5%) were nonsmokers. The mean age of the patients was 49.9 ± 15.0 years (range, 18-84 years). Of the 76 smokers and 179 former smokers, 72 (94.7%) and 166 (92.7%), respectively, were questioned about tobacco use. Smoking history and degree of nicotine dependence were higher among the former smokers (p = 0.0292 and p = 0.0125, respectively). Gender, age at smoking initiation, physician inquiry about tobacco use, and smoking cessation counseling were comparable between the two groups. The smoking cessation rate was 0.70. The prevalence of heavy smoking varied by gender and by age bracket, being higher in males and in the 41-70 year age bracket.
The smoking prevalence in this group of patients was lower than that reported for patients at another university hospital, for adults in Curitiba, and for adults in Brazil. The smoking cessation rate was higher in these patients than in the general population of Curitiba. Smokers and former smokers differed regarding age, smoking history, and degree of nicotine dependence. Heavy smoking and a moderate or high degree of nicotine dependence were not obstacles to smoking cessation.
确定某大学附属医院患者的吸烟流行率和戒烟咨询频率，并比较吸烟者和曾经吸烟者的吸烟史。
这是一项在巴西库里提巴市联邦大学临床医院进行的 629 例患者的横断面研究。
在 629 例患者中，206 例（32.7%）为男性，76 例（12.1%）为吸烟者，179 例（28.5%）为曾经吸烟者，374 例（59.5%）为不吸烟者。患者的平均年龄为 49.9 ± 15.0 岁（范围 18-84 岁）。在 76 名吸烟者和 179 名曾经吸烟者中，分别有 72 名（94.7%）和 166 名（92.7%）被询问了吸烟情况。曾经吸烟者的吸烟史和尼古丁依赖程度更高（p = 0.0292 和 p = 0.0125）。两组间的性别、吸烟起始年龄、医生询问吸烟情况和戒烟咨询并无差异。戒烟率为 0.70。重度吸烟的流行率因性别和年龄组而异，男性和 41-70 岁年龄组更高。
与另一所大学附属医院、库里提巴市成年人和巴西成年人相比，该组患者的吸烟流行率较低。与库里提巴市的一般人群相比，这些患者的戒烟率更高。吸烟者和曾经吸烟者在年龄、吸烟史和尼古丁依赖程度方面存在差异。重度吸烟和中度或高度尼古丁依赖并不是戒烟的障碍。
