RT Journal Article SR Electronic T1 Association Between Exposure to Secondhand Smoke During Pregnancy and Low Birthweight: A Narrative Review JF Respiratory Care FD American Association for Respiratory Care SP respcare.02798 DO 10.4187/respcare.02798 A1 Abdulrhman M Hawsawi A1 Lawrence O Bryant A1 Lynda T Goodfellow YR 2014 UL http://rc.rcjournal.com/content/early/2014/07/10/respcare.02798.abstract AB Exposure to secondhand smoke (SHS) during pregnancy may have adverse effects on the mother and infant. This study investigates the association of maternal exposure to SHS with low birthweight (LBW) in infants. Smoking during pregnancy has been linked to multiple complications for both mother and infant. To examine association of LBW and environmental tobacco smoke exposure during pregnancy, we reviewed 20 articles. Articles were accessed using the following electronic databases: CINAHL Plus with full text (EBSCO), PubMed, Embase, and MEDLINE. The findings of this review revealed that maternal exposure to environmental smoke is correlated with LBW in infants as well as numerous other adverse effects. The majority of the studies found negative consequences of SHS on the birthweight of infants born to nonsmoking women. Thus, this review helps to confirm the association between maternal exposure to SHS and LBW in infants.
