BACKGROUNDObstructive sleep apnoea (OSA) is a sleep-related breathing disorder characterised by full or partial occlusion of the upper airway during sleep. Obstructive sleep apnoea (OSA) is a common disorder affecting at least 2% to 4% of the adult population and can occur in all age groups.The aim of our study is to assess the usefulness of Berlin, STOP-BANG and Epworth questionnaires in evaluation of obstructive sleep apnoea and to find specificity and sensitivity of Berlin, STOP-BANG and Epworth questionnaires in predicting diagnosis of obstructive sleep apnoea. MATERIALS AND METHODSA cross-sectional study aimed at predicting high risk of OSA based on using three questionnaires in comparison to the objective assessment using the standard overnight attended PSG on all the recruited patients. The study was conducted over 62 patients at the sleep disorders laboratory of pulmonary medicine, Sri Ramachandra University Hospital, Porur, Chennai. Anthropometric measures including body weight, height, body mass index (BMI) and neck circumference (NC) as well as gender were documented for all patients. RESULTSThe incidence of OSA in our study population was 87% of which percentage of population with mild, moderate and severe OSA were 24%, 20.9% and 41.9%. The above results show that the Berlin questionnaire score is a better tool than the STOP-BANG and Epworth score, since the average accuracy of Berlin questionnaire was 66.65. CONCLUSIONThe above results show that the Berlin questionnaire score is a better tool than the STOP-BANG and Epworth score, since the average accuracy of Berlin questionnaire was 66.65. Large prospective studies will be required to help establish the exact role of subjective Berlin, STOP-BANG and Epworth sleep screening questionnaires in evaluating patient with OSA.
Objective Behavioural modification through increasing nutritional awareness, along with customised dietary changes and education about physical inactivity, for obese snorers and mildly sleep apnoeic patients would help improve their quality of life. Methods A one-year prospective interventional study enrolled snorers and/or mild obstructive sleep apnoea sufferers, with 36 patients each in the test group and control group. Nutritional information and tailor-made diet charts were given to the 36 test subjects. The severity of snoring and daytime sleepiness after 6 and 12 months was compared using the Epworth Sleepiness Scale and Thornton Snoring Scale as measures of quality of life. Results Subjective scores on both scales showed highly significant improvement (p ≤ 0.001) in the test group. No significant improvement was seen in the control group. Conclusion Awareness of basic nutrition and customised diet plans help to achieve behavioural modification in the long term, resulting in a better quality of life.
