Volunteers with and without sleep apnea needed for study

July 09, 2009

An estimated 20 million Americans have a form of sleep apnea, with most not knowing it. Researchers at Penn State Milton S. Hershey Medical Center are looking for volunteers - with and without apnea - to help study this problem.

Sleep apnea is a condition where a person stops breathing while sleeping. Relaxed muscles in the throat cause snoring and can prevent air from getting to the lungs. Breathing can stop for a short time, typically more than 10 seconds in those with apnea. Those with apnea usually have interrupted sleep, which contributes to daytime fatigue, and they usually do not know they stopped breathing throughout the night.

Researchers are studying the influence of continuous positive airway pressure, or CPAP, on sleep apnea, sleepiness and fatigue, and hormonal changes. Volunteers may be eligible if they are either a postmenopausal woman or nonobese man between the ages of 45 and 65, and a normal sleeper or one who snores and stops breathing while asleep. Those with sleep apnea should not currently be using CPAP.

A free medical assessment and compensation is provided.

This study is directed by Dr. Alexandros Vgontzas, Penn State Hershey Psychiatry. This research study has been approved by the Institutional Review Board, under federal regulations, at the College of Medicine, Penn State Hershey Medical Center.
