Association between parents’ smoking status and tobacco exposure in school-age children: assessment using major urine biomarkers

Abstract Children are at risk of exposure to secondhand smoke. We aimed to evaluate the extent of their exposure to it in relation to their parents’ smoking status by using biomarkers relevant to smoking. We evaluated 847 school-age children (6–12 years) who lived with their parents, using data from...
