Abstract
Objective: This study aimed to investigate the impact of SHS exposure on fetal biometry and umbilical artery flow at 24 – 28 weeks of gestation. Methods: This cross-sectional study included 110 pregnant women, divided into a study group (55 passive) smokers and a control group (55 non-passive smokers). Serum cotinine levels were measured using ELISA. Fetal biometry (biparietal diameter, head circumference, abdominal circumference, and femur length) and umbilical artery flow (pulsatility and resistance indices) were assessed via ultrasound and Doppler ultrasonography. Group comparisons were con
