Detailed Description
High blood pressure is a condition that normally affects adults, but can affect young children and adolescents, as well. High blood pressure in children is most commonly caused by unhealthy lifestyle or family history, but it can also be due to disease, such as kidney or heart disease. When a person has high blood pressure, the heart must work harder to pump blood throughout the body. If left untreated, high blood pressure can eventually cause damage to the heart, kidneys, and eyes. Recent studies have linked high blood pressure in children to deficits in brain functioning. However, more information is needed to confirm this connection and to determine the effectiveness of antihypertensive treatments in restoring brain function. This study will determine the effect of high blood pressure on brain functioning in children and adolescents. The study will also determine the effect of an antihypertensive treatment plan, involving a combination of diet, weight loss, increased exercise, and if needed, blood pressure medication, on brain function in children and adolescents receiving treatment for high blood pressure.
Participation in this study will last 12 months and will involve children with high blood pressure and children with normal blood pressure. Information on participants' medical history and sleep patterns, as well as parent's income and education level, will be collected. Participants with suspected high blood pressure will then undergo 24-hour blood pressure monitoring using an ambulatory blood pressure cuff. Afterwards, participants who are determined to have high blood pressure will undergo an echocardiogram of the heart. These participants will soon return to the General Clinical Research Center (GCRC) to undergo additional testing, which will include measurements of height, weight, and body mass index; a urine sampling; and a blood draw.
Before beginning potential treatment, both healthy and high blood pressure participants will complete a series of thinking and learning tests that will take about 90 minutes. Parents of participants will also be asked to answer a 10-minute questionnaire about their child's behavior and emotions. Participants with high blood pressure will then start a 12-month antihypertensive treatment plan, which will involve a combination of diet, weight loss, increased exercise, and if needed, blood pressure medication. A digital blood pressure cuff will be provided to participants for at-home blood pressure monitoring. During the treatment period, a study nurse will call participants every 1 to 2 weeks for the first 3 months and monthly for the remaining 9 months to check on blood pressure readings and to refill medications. Participants will be seen at the GCRC once every 3 to 4 months to monitor and adjust treatment as needed. Healthy participants will undergo no study treatment during the treatment phase.
Upon completion of the 12 months of treatment, all participants will undergo repeat thinking and learning tests, and parents of participants will complete repeat questionnaires. Participants with high blood pressure will also repeat the 24-hour blood pressure monitoring test.

Experimental: 1
Children with high blood pressure who will receive treatment for high blood pressure
|
Participants who are identified as having high blood pressure will be given by a pediatric nephrologist a 12-month treatment plan for their high blood pressure.
The treatment plan will include a combination of diet, weight loss, increased exercise, and if needed, blood pressure medication.
Participants receiving medication treatment will be treated with a calcium channel blocker and/or ACE inhibitor.

No Intervention: 2
Children with normal blood pressure who will undergo no treatment
