Prenatal exposure to cocaine may alter autonomic nervous system functi
on resulting in hypertension. Blood pressure was measured oscillometri
cally in a convenience sample of cocaine-exposed (n=32) and nonexposed
(n=23) children, aged 8 to 26 months, by examiners unaware of exposur
e status. The exposed and nonexposed groups did not differ in systolic
pressure (mean +/-SD 102.3 +/-9.9 mmHg vs 101.8 +/-8.1, respectively)
, diastolic pressure (45.7 +/-13.6 vs 51.7 +/-10.6), or pulse rate (11
3.0 +/-19.7 vs 119.1 +/-19.4). Prenatal exposure to cocaine does not a
ppear to be associated with elevated blood pressure in young children.
