Washington: Measuring sodium in a child's urine may help doctors identify those at risk of having high blood pressure, according to a new study.
Researchers screened 19 children, ages 10 to 19, and found that of the eight who retained sodium seven had high blood pressure.
The inability to properly excrete sodium in the body can occur during stress, such as when kids get nervous while in a doctor's office, so the children were asked to provide a urine sample before and after their visit to a physician.
Sodium retention increases fluid in the blood vessels, which can impact blood pressure. High blood pressure can develop over time if the body can't properly regulate sodium, and is a serious risk factor for heart disease and stroke.
"Hypertension is no longer an adult disease," said Gregory Harshfield, study senior researcher and director of the Institute of the Georgia Prevention Center at the Medical College of Georgia at Georgia Regents University, Augusta.
"The results of this test could also provide useful information that could help pediatricians better manage and treat hypertension in their patients," Harshfield said.
The study was presented at a meeting of the American Heart Association in New Orleans.
