TOPLINE:
Indicators of early bone loss were significantly higher in adults with severe obstructive sleep apnea (OSA) than in those with mild or moderate OSA and controls.
METHODOLOGY:
- The researchers enrolled 90 men aged 30-59 years who were patients at a single sleep and respiratory center between August 2017 and February 2019; the average age was 47.1 years, and the average body mass index was 25.7 kg/m2.
- The study population included 25 individuals with mild OSA, 21 with moderate OSA, 34 with severe OSA, and 10 controls without OSA.
- Bone loss was assessed using high-resolution peripheral quantitative computed tomography and blood samples. The researchers collected information on metabolic and inflammatory bone turnover indicators, as well as bone geometric parameters, bone microstructure parameters, and measures of bone mineral density (BMD).
TAKEAWAY:
- Total volumetric bone mineral density was significantly lower in patients with OSA than in controls and significantly different among OSA groups, as were the meta trabecular volumetric BMD, trabecular thickness (Tb.Th), and cortical thickness (Ct.Th).
- Differences in bone microstructure between patients with OSA and controls were most evident in measures of Tb.Th and Ct.Th.
- No significant differences appeared in blood bone turnover indicators or inflammation indicators among the groups.
IN PRACTICE:
“A study with a larger sample is necessary to further assess the relationship and mechanisms between OSA and osteoporosis,” the researchers wrote.
SOURCE:
The lead author on the study was Yixian Qiao, MD, of the Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China. The study was published online in BMC Pulmonary Medicine.
LIMITATIONS:
The cross-sectional design, small sample size, and inability to control for several key confounders such as nutritional status and amount of exercise, as well as the exclusion of women and elderly individuals, limited the findings.
DISCLOSURES:
The study was supported by the National Key Research and Development Projects of China. The researchers had no financial conflicts to disclose.
