PEMCS = Prenatal Exposure to Maternal Cigarette Smoking; BMI=Body Mass Index; WC = Waist Circumference; TBF=Total Body Fat; VF=Visceral Fat,
i
Puberty stage is based on a an 8-item self report measure of physical development 27.
ii
Analyzed with a χ2-statistic
iii
Relative VF is visceral fat volume divided by total body fat
