Aim:
To evaluate the prevalence of risk for obstructive sleep apnea (OSA) among patients with bipolar disorder (BD).
Methodology:
Eighty-seven patients with BD and 50 matched controls were assessed by using the Berlin questionnaire.
Results:
One-fifth of the patients with BD was found to be at high risk for OSA, compared to the 6% prevalence in the control group. Patients in high risk for OSA were more often females, had significantly higher body mass index, high waist circumference, and comorbid physical illnesses. In terms of pharmacotherapy, there was association of use of antipsychotics with higher risk of OSA at the trend level (p=0.052).
Conclusion:
The prevalence of high risk for OSA is significantly higher among patients with BD and higher prevalence is related to obesity and comorbid physical illnesses.
