Introduction: To examine the effects of opium dependence and cigarette smoking on semen quality and sperm parameters, the semen quality of men who abuse opiates and/or smoke cigarettes was investigated in a retrospective study. Methods: Male partners of 1325 infertile couples attending the infertility clinic for intrauterine insemination (IUI) procedure were divided into non-smoking non-op...
BACKGROUND It can be assumed that resettlers (ethnic German immigrants from the Former Soviet Union) show similar smoking patterns as persons in their countries of origin at the time of migration. We analysed how the smoking prevalence among resettlers differs from that among the general population of Germany and whether the prevalence differs between groups with increasing duration of stay. ...
OBJECTIVE A positive association between the number of cigarettes smoked per day and obesity has been reported, whereas how other smoking-related indices, such as pack-years and duration of smoking, are related with obesity has been less investigated. We analyzed the age-adjusted cross-sectional association between smoking and obesity in a general Japanese population. METHODS We used data fro...
This study considers the extent to which daily consumption of cigarettes in young adults varies by age at first cigarette and duration of smoking. Data come from a random sample of 21- to 30-year-old members of a large HMO in the Detroit area. Daily cigarette consumption by current smokers varied by duration of daily smoking: the longer the duration, the higher the number of cigarettes smoked. ...
Investigators typically analyze cigarette smoking using smoking duration and intensity (number of cigarettes smoked per day) as risk factors. However, odds ratios (OR) for categories of intensity either adjusted for, or jointly with, duration of smoking may be distorted by differences in total pack-years of exposure to cigarette smoke. To study effects of intensity, we apply a linear excess OR ...

Effects of Cumulative Smoking Exposure and Duration of Smoking Cessation on Carotid Artery Structure
BACKGROUND The purpose of this study was to assess the relationship of smoking duration with respiratory symptoms and history of chronic obstructive pulmonary disease (COPD) in the South Carolina Behavioral Risk Factor Surveillance System survey in 2012. METHODS Data from 4,135 adults aged ≥45 years with a smoking history were analyzed using multivariable logistic regression that accounted fo...
A smoker's risk of disease and death from cigarettes is related directly to the duration of smoking. The present study compared duration of smoking between a state-level population of Anglo versus highly acculturated Latino ever-smokers (N = 6,100). Kapla-Meier analysis was used to obtain weighted median smoking duration. Weighted Cox proportional hazard models were used to evaluate the relativ...
