Mean±SDs are shown, except for cigarette smoking for which proportions are shown.

Average values of multiple measurements for each childhood risk factor are shown.

LDL: low-density lipoprotein; HDL: high-density lipoprotein; BP: Blood pressure; baPWV: brachial-ankle pulse wave velocity

^¶only in blacks;

^†only in males;

^‡only in females

P values were adjusted for age and (race/sex) where appropriate.
