Abstract
Objective: Early detection of high blood pressure in children with family history of hypertension that can not be determined during rest, is important for early treatment and prevention of complications. Exercise test is a noninvasive and inexpensive method that can detect the increases in blood pressure due to exercise. Therefore, the aim of this study is to determine the differences in blood pressure response to exercise test between children with family history of hypertension and children without a risk factor and to evaluate the exercise recommendation in the light of these findings. Material and Methods: This study enrolled 60 normotensive aged 8-16 years. Thirty children with family history of hypertension formed the disease group while thirty without family history formed the control group. Echocardiography, resting blood pressure measurement and exercise test were performed. Results: Mean ages of the children in disease and control groups were 12.0±2.8 years and 11.7±1.8 years, respectively (p=0.58; CI:-0.88-1.55). Resting systolic blood pressure was significantly higher in the disease group compared to the control group (99.5±6.7 mmHg and 95.3 ± 8.0, mmHg respectively; p=0.03; CI=0.38-8.02). Mean diastolic blood pressures were not different among the groups (p=0.53; CI=-1.51-2.91). Maximal heart rate during exercise test was significantly higher in the disease group compared to the control group (181.5±20.3/min and 170.4±22.7/min, respectively; p=0.05; CI=0.01-22.3). Mean maximal systolic and diastolic blood pressures during exercise test children in disease and control groups were 147.8 ± 18.5 mmHg, 80.7±12.2 mmHg and 151.5±20.4 mmHg, 79.4±16.1 mmHg respectively. Blood pressures during exercise test were not significantly different between the groups (p= 0.47; p=0.72). Conclusion: The results of this study demonsrate that systolic and diastolic blood pressure responses of the normotensive children with and without family history of hypertension to exercise are not different. Also no complications were observed children during exercise test. Therefore, it was thought that exercise restriction is not required in children with family history of hypertension.
