Abstract
- OBJECTIVE: Various studies have suggested that obstructive sleep apnea (OSA) affects bone metabolism. One of the most significant factors is hypoxia which induces certain transcription factors that stimulate bone osteoclastic activity. It also induces respiratory acidosis and oxidative stress which enhances bone resorption. Leptin and melatonin secretions are regulated by the circadian system which is affected due to sleep fragmentation in OSA. Other comorbidities associated with OSA such as vitamin D deficiency, hypogonadism, obesity, and insulin resistance are indirect mechanisms that affect bone mineral density (BMD). MATERIAL AND METHODS: This is a prospective case–control study. All patients having symptoms of sleep-related breathing disorder (excluding post-menopausal females or patients with known case of osteoporosis or any other clinical illness which is a direct cause of osteoporosis) attending the Sleep Out Patient Department (OPD) were screened for OSA as per the STOPBANG questionnaire scoring system. Participants having score >2 constituted the final study population and were subjected to the polysomnography test. Participants with an apnea-hypopnea index (AHI) > 5 in polysomnography were considered as cases and those with AHI
