Abstract

Background:Maternal exposure to tobacco smoke in pregnancy is a key modifiable risk factor for baby death and disability. Smoking is linked to preterm birth (birth before 37 weeks’ gestation), stillbirth, and neonatal mortality, as well as to miscarriage, fetal growth restriction, and infant morbidity.

Methodology: Using a prospective cohort design study, 30 pregnant smokers and 34 pregnant non-smokers were recruited between march 2022 and March 2023 from Institute of Dental Sciences, Bhubaneshwar, SOA University.

Results: Thirty pregnant smokers and 34 pregnant non-smokers women were included in this study analysis. No significant difference was observed between the two groups in regards to age, amniotic fluid index, cultural and social status, number of prior miscarriages or placenta grade. Smokers had a greater number of pregnancies and births than non-smokers, with values of 3.0 [95%CI 3.0- 11.0] vs. 2.0 [95%CI 1.0-5.0] p = 0,04; 1.5 [95% CI 0.0- 7.0] vs. 1.0 [0.0 - 4.0] p = 0,04 respectively. Conclusion: It was discovered that placental blood flow had a dose-dependent effect, and resistance indices rose as tobacco smoking exposure increased. In addition, we discovered that readings of COex and urine cotinine increased in correlation with a drop in foetal birth weight.
