Increased energy intake positively associated with Sleep apnea severity
Increased energy intake regardless of diet macronutrient composition is positively associated with OSA severity according to a recent study published in the Plos One.
Obstructive sleep apnea (OSA) is characterized by upper airway obstruction during sleep, resulting in recurrent oxidative stress and sleep fragmentation. The severity of OSA is determined by the Apnea-hypopnea index (AHI), where a value of 5 to 14.9 breathing disturbances per hour of sleep is considered a mild burden, 15 to 29.9 is considered as moderate, and an AHI of 30 or greater is considered severe. The prevalence of OSA is increasing at an epidemic rate. Approximately 25% of men and 13% of women suffer from OSA worldwide [3]. A recent population-based study in Cyprus estimated that the prevalence of moderate to high risk for OSA is 50% in males and 18% in females The aim of this study was to examine whether individual nutrients (macronutrients, antioxidant vitamins) rather than energy restriction may potentially affect OSA severity in a representative population of Cyprus.
