Introduction: The STOP-BANG questionnaire is a simple screening tool for obstructive sleep apnoea (OSA) which has been validated for use in Asian populations. The original cut-off values for neck circumference were defined based on Caucasian populations. This study aims to validate the neck circumference component of the STOP-BANG score in Asians. Methods: A retrospective analysis of all patients suspected of having OSA who underwent a diagnostic polysomnography at a tertiary sleep centre in Singapore over the course of 1 year was conducted. Neck circumference was measured and correlated to the presence of OSA. A receiver operating curve was performed to obtain the optimal cut-off value for screening OSA in Asian patients. Results: 591 Asian subjects with OSA were analysed. The optimal neck circumference predictive for OSA was found to be 39 cm in males and 35 cm in females, with a sensitivity of 83.4% and 84.6% respectively. The existing STOP-BANG cut-off of 40 cm had 71% and 32% sensitivity in Asian males and females, respectively. Conclusion: The STOP-BANG cut-off value for neck circumference for screening for sleep apnoea in Asian males can be maintained at 40 cm, but the neck circumference value used for screening Asian females should be lowered to 35 cm.

Obstructive sleep apnea (OSA) is a common public health issue. If left untreated, OSA may cause a large health economic burden from cardiovascular complications particularly stroke. The diagnosis of OSA can be made by polysomnography, but its availability is limited in the developing countries in Asia. STOP-BANG questionnaire is a good screening tool but may need some adjustment for Asian population. STOP-BANG stands for: Snoring history, Tired during the day, Observed stop breathing while sleep, High blood pressure, body mass index (BMI) more than 35 kg/m2, Age more than 50 years, Neck circumference more than 40 cm and male Gender. We compared clinical features in STOP-BANG questionnaire between 42 OSA induced hypertension patients and 82 healthy control subjects in the Faculty of Medicine, Khon Kaen University, Thailand. The best cutoff point for the BMI and the neck circumference were 24.5 kg/m2 and 36 cm, respectively. The sensitivity and specificity of the BMI cutoff point were 97.2% and 91.40, while those of the neck circumference were 94.7% and 82.9%. In conclusion, the appropriate cutoff points of BMI and neck circumference for Thai STOP-BANG questionnaire were 25 kg/m2 and 36 cm.

Introduction and Aim: Prehypertension and obesity are the important cardio metabolic risk factors for developing metabolic syndrome. Neck circumference (NC) is an effective marker and screening tool for obesity. It gives a quick assessment of the upper body fat distribution. Early detection of obesity and prehypertension can increase the longevity of the individual. Hence, we aimed at evaluating the association of NC with prehypertension and obesity in young adults.   Materials and Methods: A cross sectional study where 150 Paramedical students were screened for prehypertension and fifty students were identified as pre-hypertensives (n=50). Routine anthropometric measurements were taken. NC was measured. The correlation of NC with body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) was calculated. The prevalence and percentage distribution of obesity using NC in prehypertensive was calculated. The association of NC with obesity and prehypertension was demonstrated.   Results: The prevalence of obesity in prehypertensive students was 58%. The distribution of obesity using NC was 61% in males and 55% in females. Further, the association of NC with BMI (r=0.53,p=<0.0001), SBP(r=0.52,p=<0.0001) and DBP (r=0.44, p=<0.0001) was calculated using Pearson’s correlation and was statistically significant.   Conclusion: There was an increased prevalence of obesity among pre-hypertensives with a male predisposition. The study also establishes a statistically significant and strong correlation of NC with BMI, SBP and DBP. NC can be used as an effective screening tool to assess obesity and prehypertension.

SUMMARY INTRODUCTION: Currently there has been significant growth in the number of patients with suspected obstructive sleep apnea (OSA) referred to sleep clinics. In this sense, screening and stratification methods of the severity of this pathology have become increasingly relevant. OBJECTIVE: To evaluate the performance of the NoSAS and STOP-Bang scores in the screening of OSA in a sleep clinic. METHODS: Prospectively, for 12 months, all patients referred by primary care physicians to our sleep unit for clinical evaluation and who underwent in-lab polysomnography (PSG), also completed the NoSAS score (Neck circumference, Obesity, Snoring, Age, Sex) and STOP-Bang (Snoring, Tiredness, Observed apnea, Pressure (high blood), BMI, Age, Neck circumference, Gender). A ROC (receiver operating characteristic) analysis was used to find the scores that simultaneously maximize sensitivity and specificity for each diagnosis. RESULTS: Of the 294 individuals included, 84% had OSA, of which 28.8% were mild, 34.8% moderate, and 36.4% were severe. USING THE NOSAS SCORE FOR PREDICTING OSA, MODERATE TO SEVERE OSA, AND SEVERE OSA, THE ROC AREA WAS: 0.770 (95% CI: 0.703-0.837), p<0.001, sensitivity of 57.5%, and specificity of 83.0% for a score of 12; 0.746 (95% CI: 0.691-0.802), p<0.001, sensitivity of 68.2% and specificity of 75.4% for a score of 13; 0.686 (95% CI: 0.622-0.749), p<0.001, sensitivity of 71.1% and specificity of 58.3% for a score of 13, respectively. USING THE STOP-BANG SCORE FOR PREDICTING OSA, MODERATE TO SEVERE OSA, AND SEVERE OSA, THE ROC AREA WAS: 0.862 (95% CI: 0.808-0.916), p<0.001, sensitivity of 68.4% and specificity of 85.1% for a score of 5; 0.813 (95% CI: 0.756-0.861), p<0.001, sensitivity of 77.3% and specificity of 66.1% for a score of 5; 0.787 (95% CI: 0.732-0.841), p<0.001, sensitivity of 70.0% and specificity of 79.9% for a score of 6, respectively. CONCLUSIONS: The ROC area was consistently high for both scores confirming the diagnostic ability of the NoSAS and STOP-Bang questionnaires for all OSA severities. Thus, our results suggest that these questionnaires may be a powerful tool for the screening and stratification of patients in the diagnosis of OSA. Overall, the diagnostic ability of the STOP-Bang was higher than the NoSAS.
