Factors related to the severity of obstructive sleep apnea in the elderly
[Objective]To investigate the factors related to the severity of obstructive sleep apnea(OSA)in elderly patients.[Methods]The patients receiving polysomnosis monitoring were divided into non-elderly group(age＜65 years,n=37)and elderly group(age ≥65 years,n=43).OSA severity was determined by the apnea hypopnea index(AHI),and each group was further divided into two subgroups:mild to moderate OSA(5＜AHI＜30)and severe OSA(AHI≥30).In the older group,geriatric assessments were performed to analyze physical and neuropsychiatric function.[Results]BMI of OSA patients in non-senile group and senile group was positively correlated with AHI,while age was only correlated with AHI in senile group.In the elderly group,BMI and age of patients with severe OSA were higher than those with mild-moderate OSA.There were no significant differences in physical strength,cognitive function,apathetic scale,depression scale or activities of daily living between mild to moderate OSA and severe OSA subgroups(P＞0.05).Binary logistic regression analysis showed that male,body mass index,and age were independent risk factors for severe OSA in the elderly group.[Conclusion]Aging increases the severity of OSA in elderly patients,and this relationship is independent of physical activity and neuropsychiatric status.
