Objectives: The primary objective was to correlate aortic intima-media thickness (aIMT) measured at L1-L2 with birth weight in neonates born at ≥35 week of gestation. The secondary objective was to compare aIMT in small for gestational age (SGA) and appropriate for gestational age (AGA) babies in this cohort. Methods: Prospective observational study enrolling 200 newborns. aIMT was measured on day 3 of life using 10-12 MHz ultrasound probe. Relevant maternal and baby details were collected and analyzed. Results: Mean (SD) aIMT was 0.43 (0.15) mm. There was a negative correlation between aIMT and birthweight (r= -0.64). Mean (SD) aIMT in AGA was significantly lesser than in SGA babies (0.36 (0.11) vs. 0.64 (0.08) mm; P
