    Abstract:
    Hypertension is an increasing disease in children and the risk of endothelial damage and target organ damage increases in the presence of additional risk factors such as obesity. In our study, the effect of hypertension on early atherosclerotic changes and target organ damage in children was investigated. Twenty four-hour ambulatory pulse wave analysis was performed by oscillometric method in 71 children aged 8-18 years, 17 of whom were diagnosed with primary hypertension without obesity, 18 had both primary hypertension and obesity, and 16 had renal hypertension. Twenty healthy normotensive children were included as the control group. Carotid intima-media thickness (CIMT) and Left Ventricular Mass Index were measured. Central systolic blood pressure (cSBP), central diastolic blood pressure (cDBP), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were higher in the primary hypertension group compared to controls (p = 0.001, p = 0.005, p = 0.001, p = 0.009, respectively), cSBP was higher in the renal hypertension group than the control group (p = 0.018). There was no difference between the groups in terms of pulse wave analysis parameters, CIMT, or left ventricular mass index (p > 0.05). Pulse wave velocity was positively correlated with SBP, DBP, cSBP, cDBP (p < 0.001). Augmentation index was positively correlated with DBP and cDBP (p = 0.01, p = 0.002, respectively). Our findings show that high blood pressure is associated with arterial stiffness and target organ damage beginning in childhood. The detection of early atherosclerotic vascular changes using pulse wave analysis allows to take necessary precautions such as lifestyle changes to prevent target organ damage in hypertensive children.
