Evaluating the risk of obstructive sleep apnea in type 2 diabetic patients, and its associations
2015
OBJECTIVE: To assess the prevalence of high risk of Obstructive Sleep Apnoea (OSA) in Type 2 diabetics. To identify risk associations of OSA with obesity, sleep quality, daytime sleepiness and Acanthosis Nigricans. DESIGN AND METHODS: A cross sectional study was done in the diabetic wards of health facilities governed by three Regional Health Authorities in Trinidad. OSA risk was assessed by the Snoring, Tiredness, Observed Apnea, high blood Pressure (STOP) u Body mass index, Age, Neck circumference and Gender (BANG) questionnaire. Sleep quality and daytime sleepiness were also assessed by the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale respectively. Bioimpedance analysis was also done using a stadiometer and standard bioimpedance scale. RESULTS: A total of 281 diabetic patients and 147 non-diabetic patients were interviewed throughout Trinidad. Females made up the majority of the sample, 67% of the diabetics and 66% of the non diabetics. The prevalence of OSA was found to be 73.2% in type 2 diabetics. Non diabetics had an OSA prevalence of 39.5%. Results from a binary regression showed that having diabetes increased the probability of oHigh Risk of OSAo by 93.1%. CONCLUSION: The prevalence of high risk of OSA in Trinidad was high in type 2 diabetic patients, and has strong correlations with obesity and Acanthosis Nigricans.
