BACKGROUND/AIMS Smoking is widely acknowledged as the single most important risk factor for chronic obstructive pulmonary disease (COPD). However, the risk of COPD in nonsmokers exposed to secondhand smoke remains controversial. In this study, we investigated the association of secondhand smoke exposure with COPD prevalence in nonsmokers who reported never smoking. METHODS This study was base...

T science is clear: Secondhand tobacco smoke causes premature death and disease in children and adults who don’t smoke—and there is no safe exposure level, U.S. Surgeon General Dr. Richard H. Carmona warned in a comprehensive new report. In a return to a public health issue last addressed in a 1986 surgeon general’s report, the nation’s top physician found significant progress in the campaign t...

Heart disease is the leading cause of death in the United States, according to the Centers for Disease Control and Prevention (CDC). An American has a coronary event (heart attack) nearly every 25 seconds, resulting in death about every minute. Smoking is the leading risk factor for heart disease. Evidence suggests that exposure to secondhand smoke also can result in adverse health effects, inc...

INTRODUCTION During the past 30 years, local and state tobacco use control laws in the United States have helped reduce smoking prevalence and exposure to secondhand smoke, but progress among low socioeconomic populations has been slow. Implementing smoke-free housing policies in affordable housing may help address this issue. The purpose of our study was to assess how such policies affect smok...

Due to their relatively homogeneous lifestyle and living environment, the Amish offer a novel opportunity to study the health associations of tobacco smoke exposure, particularly secondhand smoke. We hypothesized that secondhand smoke exposure is associated with worse pulmonary and cardiometabolic health. We examined cross-sectional data on 3568 Amish study participants, including tobacco use a...

It is indicated that children are involuntarily exposed to secondhand smoke from adults, mainly at their home environment. This study aimed at describing the effectiveness of the school-based intervention to decrease the in-home smoking situation of adults so as to decrease children's exposure to secondhand smoke at home during the year 2011-2012 in a rural district in Hanoi, Viet Nam. This sch...
