Our findings demonstrate lower rates of CPAP acceptance among older patients aged > 75 years. To date, the few observational studies examining the effect of age on CPAP acceptance have reported conflicting results. Rezaie et al examined predictors of CPAP acceptance among a cohort of patients from Iran and found that age was not associated with CPAP acceptance. Simon-Tuval et al reported a higher mean age among CPAP acceptors in a population in Israel. In Tai-wanese cohorts, Huang et al13found that CPAP acceptance was greater among patients aged < 55 years, while Yang et al found that CPAP acceptance was higher among patients aged 65 years.
