CIMTd, difference in carotid intima-media thickness; WHO, World Health Organization.

Excluding residuals >2 or <−2.

^†

Adjusted for child’s age at CIMT scan, sex, BMI, systolic blood pressure, asthma status, race/ethnicity, delivery mode, maternal pregnancy complications, income, and study area.

^‡

Sample excluding the 33 children without data on gestational age from birth records.

^§

WHO growth charts: sex-specific birth weight of healthy newborns.
