Abstract
Introduction
Sleep apnoea syndrome (SAS) is a frequent and underdiagnosed pathology. Epidemiological studies in sub-Saharan Africa
are few. Our study aimed to determine the prevalence of SAS symptoms in an adult population in Burkina Faso.
Methods
A cross-sectional study whose data collection took place at the Yalgado Ouédraogo Teaching Hospital, from 1 September to 31
October 2014. We randomly enrolled all subjects aged at least 25 accompanying an outpatient t the time of a visit. A strong suspicion of SAS
was established for every combination of ordinary snoring with excessive daytime sleepiness and/or sleep apnoea.
Results
The study included 311 subjects – 181 men and 130 women. The mean (standard deviation (SD)) age was 31.84 (8.25) years and
the average (SD) BMI was 23.14 (3.67) kg/m². The prevalence of excessive daytime sleepiness, snoring and sleep apnoea was 4.5%, 26% and
9.6%, respectively. A strong suspicion of SAS was found in 9.6% of respondents and the risk factors associated with this strong suspicion
were BMI≥25 kg/m² (odds ratio (OR) 2.7; p=0.012), and poor-quality sleep (OR 3.7; p<0.001).
Conclusion
A significant proportion of our sample had symptoms suggestive of SAS. Testing with either respiratory polygraphy or
polysomnography should be proposed to the presumptive cases for early diagnosis and treatment.
