The mean arterial blood (MAP) pressure is considered to be a useful index in the adult to detect the development of hypertension during pregnancy. Even though pregnant teenagers are considered to be at the highest risk for this disorder, MAP standards have not been developed for this age group. Therefore, the MAPs of one hypertensive and one normotensive pregnant adolescent were reviewed and compared with MAP adult standard values that are predictive of future pregnancy-induced hypertension.

The second trimester MAP of the hypertensive adolescent was similar to the adult standard that is indicative of hypertension. Her elevated MAP could have been recognized before an increase in the systolic and diastolic blood pressure values. The normotensive adolescent exhibited no such rise in her second trimester MAP. The use of the MAP during the second trimester of adolescents' pregnancies should be explored further to anticipate and potentially minimize the adverse effects of pregnancy-induced hypertension for young gravidas.
