13 Dec Osteoporosis risk heightened among sleep apnoea patients
Sleep apnoea is a condition that causes brief interruptions in breathing during sleep. Obstructive sleep apnoea, the most common form, occurs when a person’s airway becomes blocked during sleep. If sleep apnoea goes untreated, it can raise the risk for stroke, cardiovascular disease and heart attacks.
“Ongoing sleep disruptions caused by obstructive sleep apnoea can harm many of the body’s systems, including the skeletal system,” said one of the study’s authors, Kai-Jen Tien, MD, of Chi Mei Medical Centre in Tainan, Taiwan. “When sleep apnoea periodically deprives the body of oxygen, it can weaken bones and raise the risk of osteoporosis. The progressive condition can lead to bone fractures, increased medical costs, reduced quality of life and even death.”
The retrospective cohort study used records from Taiwan’s single-payer National Health Insurance program to track treatment of 1,377 people who were diagnosed with obstructive sleep apnoea between 2000 and 2008. During the course of the next six years, researchers compared the rate of osteoporosis diagnosis in this group of obstructive sleep apnoea patients to 20,655 people comparable in age and gender who did not have the sleep disorder.
Researchers found the incidence of osteoporosis was 2.7 times higher among patients with sleep apnoea than their counterparts, after adjusting for age, gender, other medical problems, geographic location and monthly income. Women and older individuals faced increased risk of developing the bone condition.
“As more and more people are diagnosed with obstructive sleep apnoea worldwide, both patients and health care providers need to be aware of the heightened risk of developing other conditions,” Tien said. “We need to pay more attention to the relationship between sleep apnoea and bone health so we can identify strategies to prevent osteoporosis.”
Other authors of the study include: Yu-Li Chen, Shih-Feng Weng, Chien-Wen Chou, Chwen-Yi Yang and Jhi-Joung Wang of Chi Mei Medical Center, and Yuan-Chi Shen of Kaohsiung Chang Gung Memorial Hospital in Kaohsiung, Taiwan.
The study, “Obstructive Sleep Apnoea and Risk of Osteoporosis: A Population-Based Cohort Study in Taiwan,” was published online, ahead of print.
