Abstract
BACKGROUND: Obstructive sleep apnea (OSA) is a fairly common problem with adverse health consequences. However, any screening questionnaire is not available in Hindi to screen sleep apnea. MATERIALS AND METHODS: Subjects undergoing video-synchronized in laboratory attended polysomnography were requested to participate in this study. They were screened with the help of Hindi version of Berlin questionnaire (BQ). Outcome of the BQ was tested against the gold standard polysomnography. Descriptive statistics, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of Hindi version were calculated. RESULTS: 38 patients with polysomnography diagnosed OSA and 12 controls were included in this study. Average body mass index (BMI) in the OSA group was 33.12 + 6.66 kg/m(2) whereas in the control group BMI was 25.01 + 4.20 kg/m(2). Average age in the OSA group was 48.9 + 10.2 years whereas the control group was older (56.9 + 12.1 years). Hindi version had sensitivity of 89% and specificity of 58%. PPV of the instrument was 0.87 whereas NPV was 0.63. CONCLUSION: Hindi version of BQ is a valid tool for screening the OSA irrespective of the literacy status of the subjects.
