INTRODUCTION Due to the interaction between smoking and the virus and the antiretroviral therapy, the excess health hazard due to smoking is higher in HIV+ patients than in the general population. International studies suggest a higher prevalence of smoking in HIV+ subjects compared to the general population. It was the aim of the study to assess prevalence of smoking, to analyze determinants o...

BACKGROUND Various pivotal stages in smoking behavior can be identified, including initiation, conversion from experimenting to established use, development of tolerance, and cessation. Previous studies have shown high heritability for age of smoking initiation and cessation; however, time-to-event genome-wide association studies aiming to identify underpinning genes that accelerate or delay th...

The present study tested the hypothesis that impulsivity would predict perceptions of positive and negative reinforcement from smoking. The secondary hypothesis was that the relationship between impulsivity and smoking reinforcement expectations would be mediated by the character trait of self-directedness. College students (n=202) who reported smoking cigarettes participated in the survey stud...

INTRODUCTION Cigarette smoking is the single greatest preventable cause of disease and death. Our literature review highlights the increased risk of cigarette smoking and kidney cancer, bladder cancer and prostate cancer. MATERIAL AND METHODS Smoking cessation improves outcomes at all stages of these disease processes, where patients who quit for 10-20 years appear to obtain a similar risk as...

To address the question of whether sex differences in mortality will in the future rise, fall, or stay the same, this study uses relative smoking prevalence among males and females to forecast future changes in relative smoking-attributed mortality. Data on 21 high income nations from 1975 to 2000 and a lag between smoking prevalence and mortality allow forecasts up to 2020. Averaged across nat...

OBJECTIVE To describe a series of cases of tobacco chippers (TCs) who sought assistance for smoking cessation. DESCRIPTION OF CASES We describe the case of three TCs who participated in a free quit-smoking support group. Smokers answered self-administered questionnaires covering sociodemographic data, smoking history, nicotine dependence, perceived health status, and motivational stages. Of t...

Smoking-related behaviors and attitudes of significant others (especially friends and parents) are among the most consistent predictors of adolescent smoking. However, theorists remain divided on whether the behaviors of significant others influence adolescent smoking directly or indirectly, and the relative influence of parental and peer smoking on adolescents' own smoking is still a matter of...
