Introduction:
The aim of this study was to describe the profile of patients followed up for obstructive sleep apnea syndrome (OSAS) and to identify factors associated with adherence to its treatment in a referral centre in Cotonou.
Method:
This is a retrospective cohort study at the National teaching hospital for tuberculosis and pulmonary diseases and included all patients followed for OSAS from July 2014 to December 2024. Data were collected from patient records.
Results:
A total of 503 patients were included. They were predominantly male (64.1%) and overweight/obese (92.3%) with a mean age of 55.1±11.6 years. Hypertension was the main comorbidity (73.9%). OSAS was moderate to severe in 88.10% of the patients. Compliance was good to average in 70.30% of cases. The severity of OSAS was the only factor associated with good compliance with continuous positive airway pressure (CPAP) treatment (ORa: 2.11, IC95%: 1.21-3.82, P=0.011).
Conclusion:
The majority of patients treated for OSAS in Cotonou were in their fifties, obese and hypertensive. The only factor associated with compliance with CPAP treatment was the severity of the OSAS.
