title: [Trends in prevalence of continuous positive airway pressure treatment for adults from 2006 to 2010].
abstract: BACKGROUND
  The aim of this study was to evaluate the evolution from 2006 to 2010 of the prevalence of continuous positive airway pressure treatment for the beneficiaries of two regional health care insurance funds (17 and 43).
  
  
  METHODS
  One million forty-eight thousand four hundred and thirty beneficiary-years were analyzed from 2006 to 2010. The prevalence of continuous positive airway pressure treatment was tested with regard to the effect of the year of delivery. A logit regression was used to adjust for potentially confounding differences in age and gender, which were included as covariates. The prevalence of alternative treatments and of controls of reimbursement benefits implemented by the funds are evaluated too during the same period.
  
  
  RESULTS
  Continuous positive airway pressure treatment annual prevalence was 6.34/1000. A significant annual increase of prevalence from 2006 to 2008 was followed by a slowing of the rate of growth starting from 2008. In the same time for fund 43, obesity surgery rose from 41.85/100,000 to 55.44/100,000 and mandibular osteotomy surgery rose from 0.97/100,000 to 4.78/100,000. For fund 17 mandibular advancement devices rose from 10.72/100,000 to 21,08/100,000. The two funds started a reinforced inspections of reimbursement benefits for continuous positive airway pressure treatment in 2008.
  
  
  CONCLUSIONS
  The dynamics of continuous positive airway pressure treatment have to be considered in the context of policies introduced and trends in the application of alternative treatments in each fund.
