May 7 2024University of Colorado Anschutz Medical Campus As part of the University of Colorado Department of Medicine's annual Research Day, held on April 23, faculty member Christine Swanson, MD, MCR, described her National Institutes of Health-funded clinical research on whether adequate sleep can help prevent osteoporosis.
How bone density and sleep change over time In people's early- to mid-20s, they reach what is called peak bone mineral density, which is higher for men than it is for women, Swanson said. This peak is one of the main determinants of fracture risk later in life. "And it's not just sleep duration and composition that change. Circadian phase preference also changes across the lifespan in both men and women," Swanson said, referring to people's preference for when they go to sleep and when they wake up.
"This rhythmicity is likely important for normal bone metabolism and suggests that sleep and circadian disturbance could directly affect bone health," she said.
