Volunteers sought for sleep study

The Grand Forks Human Nutrition Research Center is seeking men and women age 51 and older to be part of the magnesium nutrition and sleep behavior study. Participants can earn up to $300 for participating.

This study will determine if the amount of magnesium in diet and body is associated with sleep patterns, and to identify factors (gender, health, diet, body composition, physical activity, depression) that may affect the relationship between magnesium nutrition and sleep.

To be eligible, participants should have sleep complaints but not taking sleep medications. They must not be morbidly obese and currently not taking high amounts of magnesium through supplements (100 milligrams a day or more). This study is open to non-smokers and smokers.

Participants will take a supplement (placebo or 300 milligrams of magnesium) every day for seven weeks; visit the Nutrition Center 13 times over eight weeks; wear a small physical activity monitor attached to wrist band or small belt for five consecutive days three times during study (total 15 days); complete questionnaires; and have blood drawn four times.
