Table 3 Adjusted odds ratios for newborn macrosomia and low birth weight for women exposed and non-exposed to SHS stratified by BMI

From: The independent effects of second hand smoke exposure and maternal body mass index on the anthropometric measurements of the newborn

Newborn measurement Non-obese Underweight Obese
BMI = 18-29.99 BMI < 18 BMI ≥ 30
