Background: Obstructive sleep apnoea (OSA) is a common medical condition which has long been recognized as a major contributor to morbidity and mortality in developed countries but that remains underdiagnosed, particularly in rural communities. This study aimed to assess the prevalence of adults who have a high risk of obstructive sleep apnoea in a sample of adults living in Ejigbo, a rural community in south western Nigeria.
Methods: This was a community-based cross-sectional descriptive study done to assess the prevalence of high risk of obstructive sleep apnoea in adult residents of the community using the STOP-BANG questionnaire. Data collected include socio-demographic characteristics, anthropometric measurements and blood pressure. A blood sample was also taken for lipid profile. Factors associated with a high risk of obstructive sleep apnoea were identified.
Results: The study involved 257 participants out of which 88 (34.2%) had a high risk of OSA. Risk of obstructive sleep apnoea was significantly associated with male sex (p<0.001), age (p<0.001), body mass index (BMI) (p=0.001), neck circumference (p<0.001), cigarette smoking (p=0.039) and low density lipoprotein (p=0.043).
Conclusion: Obstructive sleep apnoea is relatively common in the study area. This calls for urgent preventive measures to stem the tide and mitigate the associated morbidity and mortality.
