Compared to nonsmokers, mothers who smoke during pregnancy tend to produce infants who have what characteristic?

Mothers who smoke during pregnancy are associated with producing infants who have lower birth weights. This outcome is primarily due to the harmful effects of nicotine and other chemicals present in cigarette smoke, which can restrict blood flow to the placenta and impede fetal growth. Additionally, smoking can lead to complications such as placental abruption or placenta previa, both of which can contribute to lower birth weights.

Low birth weight is a crucial indicator of neonatal health and is linked to increased risks of developmental problems and other health complications later in life. The impact on birth weight is well-documented, establishing a clear connection between maternal smoking and reduced fetal growth. Thus, lower birth weights in infants born to mothers who smoke aligns with established research and clinical findings in obstetrics.
