Abstract
This study included 300 term-newborn (mean standard deviation 37+-3) delivered at Obstetrics and Gynecology department ,Ain-Shams university and was divided into 3 groups:
Group A: 100 term born to actively smoking mothers (smoking cigarettes or shisha)
Group B: 100 term born to non- actively (passively) smoking mothers
Group C: 100 term born to non- actively, non smoking mothers.
This study aimed to evaluate the role of maternal smoking whether (active or passive) on newborn’s birth weight, Length, skull circumferences, chest circumference and mid arm circumference.
Neonates with history of multiple birth or having history of congenital anomalies were excluded ,also mothers who used illicit substances during pregnancy other than tobacco smoke or stopped smoking during pregnancy also were excluded.
Also our study shows significant relations between high socioeconomic levels and maternal smoking also between smoking and cause of hospitalization due to pregnancy complications in form of abortions, preterm labors and abruption placenta.
It also found significant relation ship between maternal smoking and increasing incidence of caesarian sections.
As it showed significant relation between smoking and lower weight gain during pregnancy which affect the weight of their newborns leading to significant increase in the incidence of low birth weight and also significant lower gestational age leading to preterm labors and consequently this increase incidence of NICU admissions of their newborns.
The results showed significant decrease in the anthropometric measures of their newborns (weight, length, head circumference, chest circumference and mid-arm circumference) with dose dependant relationship affecting mainly weight and mid arm circumference.
