In overweight and obese men, higher testosterone levels are associated with poorer sleep quality, according to a new study.

"This finding could have clinical relevance in the context of the recent increase in testosterone prescriptions in middle-aged men, as poor sleep quality has been linked to increased risk of diabetes and hypertension," said Eve Van Cauter, PhD, the study's senior investigator. She is director of the University of Chicago Sleep, Metabolism and Health Center, where the study took place.

With three of four U.S. men now overweight or obese, the researchers wanted to determine which factors influence sleep quality in this population. Overweight and older age can contribute to obstructive sleep apnea (OSA), a condition in which breathing repeatedly stops and starts during sleep and which disrupts sleep.
