Measuring prenatal secondhand smoke exposure in mother-baby couplets.

Introduction

Pregnant women often underreport their smoking status and extent of secondhand smoke (SHS) exposure. Biomarker confirmation is the recommended method to assess smoking behaviors and SHS exposure in both mothers and infants.
