Relation of exposure to secondhand tobacco smoke during pregnancy and early childhood with adolescents body composition and cardiometabolic health: a cohort study

Exposure to secondhand tobacco smoke (SHS) is a worldwide public health problem and children are a particularly vulnerable population due to their anatomical, physiological, and behavioral characteristics. Cotinine concentrations in saliva, blood, and hair have become the most widely used biomarkers...
