OBJECTIVE To examine the risk of breast cancer associated with passive and active smoking and to explore risk heterogeneity among studies. METHODS We conducted this study in Iran during the year 2006. Fifteen published studies on smoking and breast cancer met the defined criteria. Pooled odds ratio (OR) estimates for female breast cancer were calculated. The active and passive smokers were co...

Male schizophrenia patients are known to have a heavier smoking pattern compared with the general population. However, the mechanism for this association is not known, though hypothesis that smoking could alleviate symptomatology of schizophrenia and reduce side effects of antipsychotics has been suggested. The aims of this study were to validate the heavier smoking pattern among male schizophr...

Although clinic-based studies have used biochemical validation to estimate the percentage of pregnant women who deny smoking but are actually smokers, a population-based estimate of nondisclosure of smoking status in US pregnant women has not been calculated. The authors analyzed data from the 1999–2006 National Health and Nutrition Examination Survey and estimated the percentage of 994 pregnan...

BACKGROUND Studies suggest that tailored materials are superior to nontailored materials in supporting health behavioral change. Several trials on tailored Internet-based interventions for smoking cessation have shown good effects. There have, however, been few attempts to isolate the effect of the tailoring component of an Internet-based intervention for smoking cessation and to compare it wit...

BACKGROUND Smoking cessation programs are well established in the West, but reports on smoking cessation clinics (SCCs) from China are lacking. On the basis of the Hong Kong experience and with strong support from Guangzhou Health Bureau, we established the first SCC in Guangzhou, China. The objective was to describe the characteristics of smokers, measure quit rates and examine predictors of s...

BACKGROUND Hookah smoking is growing in popularity especially among women but little is known about the determinants influencing on hookah smoking initiation. In order to address this emerging health risk, a qualitative study was conducted to explore the factors that contribute in the first hookah smoking trial by women. METHODS This qualitative study was conducted during 2012 to 2013 in Tehr...

INTRODUCTION Use of online social networks for smoking cessation has been associated with abstinence. Little is known about the mechanisms through which the formation of social ties in an online network may influence smoking behavior. Using dynamic social network analysis, we investigated how temporal changes of an individual's number of social network ties are prospectively related to abstinen...

Quitting cigarette smoking benefits smokers at any age (1). Individual, group, and telephone counseling and seven Food and Drug Administration-approved medications increase quit rates (1-3). To assess progress toward the Healthy People 2020 objectives of increasing the proportion of U.S. adults who attempt to quit smoking cigarettes to ≥80.0% (TU-4.1), and increasing recent smoking cessation su...

BACKGROUND The prevalence of cigarette smoking in the United States has decreased, but current rates remain above nationally set objectives. A family history of lung cancer may motivate adult smokers to quit and contribute to further reductions in smoking prevalence. METHODS We surveyed adult smokers (N = 838) interviewed as part of the 2005 Health Information National Trends Survey. We exami...

BACKGROUND Patients with lung cancer with mutations in EGF receptor (EGFR) tyrosine kinase have improved prognosis when treated with EGFR inhibitors. We hypothesized that EGFR mutations may be related to residential radon or passive tobacco smoke. METHODS This hypothesis was investigated by analyzing EGFR mutations in 70 lung tumors from a population of never and long-term former female smoke...
