中国健康与养老追踪调查中睡眠时长轨迹与听力损失关联研究OA

OBJECTIVE To investigate the association between sleep duration trajectories and hearing loss among community-dwelling adults using data from the China Health and Retirement Longitudinal Study(CHARLS).METHODS Data were derived from four waves(2011-2018)of the CHARLS.Group-based trajectory modeling(GBTM)was employed to identify distinct sleep duration trajectories over time.Multivariable logistic regression analyses were then performed to evaluate the associations between different sleep duration trajectory groups and hearing loss,adjusting for demographic characteristics and metabolic-related confounding factors.RESULTS Model fit indices decreased with an increasing number of trajectory groups;however,the five-group model showed an average posterior probability(APP)<0.7.Based on overall model performance,a three-trajectory model was selected.Sleep duration patterns were classified as healthy increas sleep trajectory(n=583),persistent short sleep(n=1,175),and fluctuating insufficient sleep(n=1,403).Significant differences in demographic and metabolic characteristics were observed among the three groups.After adjustment for cardiometabolic factors,persistent short sleep was significantly associated with an increased risk of hearing loss(OR=1.321,P<0.05).The association was more pronounced in participants aged≥59 years(OR=1.491,P=0.018),whereas no significant association was observed in those aged<59 years.CONCLUSION Persistent short sleep trajectory is significantly associated with hearing loss,particularly among older adults.Chronic sleep deprivation may represent an important risk factor for age-related hearing loss.
