RESUMO
Hypertension is a growing health problem in children, and it is an important parameter of cardiovascular risk for adults. It is classified as primary (influenced by obesity, sedentary lifestyles and poor-quality food) or secondary to underlying causes. The AAP 2017 guidelines recommend measuring blood pressure every year from the age of three and in children under the age of three only if they have known risk factors. The measurement of infantile hypertension is relatively complicated and instable and, for this reason, ambulatory blood pressure monitoring (ABPM) and multiple office BP measurement (mOBPM), especially in infants who are not collaborating are indicated. High blood pressure may have an adverse effect on the heart, the vessels, the kidney, and the central nervous system so it is important recognize it and act promptly. Hypertension is initially treated with lifestyle changes such as weight loss, a healthy diet, and regular exercise, but, if non-pharmacological interventions have failed, a pharmacological treatment with angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, calcium channel blockers, thiazide diuretics and/or beta blocker may be indicated.
