Secondhand smoke exposure (SHSe) is a known cause of many adverse health effects in adults and children. Increasingly, SHSe assessment is an element of tobacco control research and implementation worldwide. In spite of decades of development of approaches to assess SHSe, there are still unresolved methodological issues; therefore, a multidisciplinary expert meeting was held to catalogue the app...

BACKGROUND Environmental tobacco smoke (ETS) in the home continues to be a major health risk for children around the world. Measuring ETS is a central feature of clinical and epidemiological studies, with children's exposure often assessed through parental estimates. The authors examined the relationship between parent-reported estimates of children's exposure to ETS and children's urinary coti...

High-level occupational radon exposure is an established risk factor for lung cancer. We assessed the long-term association between residential radon and lung cancer risk using a prospective Danish cohort using 57,053 persons recruited during 1993-1997. We followed each cohort member for cancer occurrence until 27 June 2006, identifying 589 lung cancer cases. We traced residential addresses fro...

Japan has put forward a conceived model named Air Pollution Prevention Alliance between Japan and China. This article analyzes the background and causations of air environmental pollution problems in China, and the efforts that Chinese government...

We propose that in utero exposure to tobacco smoke products places a newborn at risk for persistent pulmonary hypertension of the newborn (PPHN). To test this hypothesis, infants with PPHN were identified. Healthy newborns of similar ethnicity were identified as a comparison group. Cord blood cotinine concentrations and maternal questionnaires were obtained. The number of women exposed to tobac...

KEY FINDINGS Data from the National Health and Nutrition Examination Survey, 1999-2010. From 1999 to 2010, the percentage of children without asthma exposed to environmental tobacco smoke (ETS) decreased from 57.3% to 44.2%, while children with asthma showed no change, with 57.9% exposed to ETS in 1999-2002 and 54.0% exposed in 2007-2010. In 2007-2010, a higher percentage of children with asthm...

It is now well established that children's exposure to environmental tobacco smoke (ETS) results in substantial public health and economic impacts. Children are more likely than adults to suffer health effects from ETS exposure, and the home is the most important site of such exposure. Although the responsibility and authority of the community and health professionals to protect children from h...
