Study links snoring to hypertension
NEW YORK (CNN) -- Snoring may contribute to high-blood pressure, according to a new study.
Researchers studied sleep and cardiovascular information on 6,132 people who were at least 40 years old. Suspension of breathing -- often while snoring -- induces stress, and stress increases the risk of hypertension, researchers said.
Doctors at the Johns Hopkins School of Hygiene and Public Health in Baltimore and other participants in the study found that the risk of high-blood pressure increased with the severity of the apnea, or suspension of breathing.
"We found that there's evidence of sleep apnea and high-blood pressure both in younger and older individuals, both in men and women, and both in white, African Americans and native Americans and other groups," said Dr. F. Javier Nieto of Johns Hopkins.
Accompanying the report, published this week in the Journal of the Americal Medical Association, was an editorial written by Dr. Clifford W. Zwillich of the Veterans Affairs Medical Center in Denver.
He said treating apnea was not realistic approach to reducing hypertension.
Apnea may be caused by dysfunction of the brain center controlling respiration or by obstruction of the airway. The AMA Family Medical Guide noted that the obstructive form of apnea is more common in overweight people.
