Obstructive sleep apnea syndrome (OSAS) is a common condition in patients undergoing chronic dialysis and is associated with increased cardiovascular morbidity and mortality. This study aimed to determine the prevalence and risk factors of OSAS in Senegalese dialysis patients. In a cross-sectional study including 128 patients (75 men and 53 women) dialyzed since ≥6 months in four dialysis units. Data were collected during the dialysis session in the units. OSAS was assessed with the Berlin Questionnaire. Factors associated with OSAS risk were identified by multivariate logistic regression. The mean age of patients was 46.8 ± 16.9 ¥16–85 years). OSAS was found in 53 patients (overall prevalence of 41.4%) with predominance among individuals aged ≥50 years (52.6%). Hypertension and diabetes were more frequent in patients with OSAS, while the prevalence of obesity and sedentary was not different. The majority of patients were not aware of their disease before the survey, and none was treated. After multivariate regression analysis, age >50 years [odds ratio (OR) = 1.09, P = 0.02], neck circumference >45 cm (OR= 1.25, P= 0.03), and daytime hypersomnia (OR = 1.18, P= 0.02) were significantly associated with OSAS. This study showed that OSAS is frequent among Senegalese dialysis patients but is usually under-diagnosed. Older age, excessive daytime sleepiness, and neck circumference are the main associated factors.
