    Abstract:
    AIMS: To assess whether a gender difference exists in adolescent hypertension and its target organ damage and to compare potential confounding factors and target organ damage in hypertensive and normotensive adolescent girls. METHODS: From the Debrecen Hypertension Study, the anthropometric, blood pressure, and laboratory data as well as intima-media thickness (IMT) and left ventricular mass index (LVMI) of 58 hypertensive boys, 56 hypertensive girls, and 30 normotensive girls were analyzed. RESULTS: Both systolic and mean blood pressure values were higher in adolescent hypertensive boys than in girls. This difference was also present when comparing 24-hour average blood pressure values. Plasma concentrations of nitric oxide (NO) and endothelin-1 were not different in the two gender groups. IMT of the carotid arteries were similar in hypertensive boys and girls, but a significantly higher LVMI was detected in boys. A significant difference was detected in anthropometric data (height, weight, and body mass index [BMI]), plasma concentration of NO (lower levels in hypertensives), and IMT in hypertensive and normotensive girls (higher IMT in hypertensive girls). CONCLUSIONS: There is a difference between the severity of hypertension between hypertensive adolescent girls and boys. Hypertensive girls differ from normotensive girls not only in blood pressure values but also in risk factors and subclinical target organ effects. Further studies are needed to explain the gender differences in adolescent hypertension. The potential role of sex hormones in hypertensive teenagers also needs to be clarified in future works.
