Abstract


1.1      Background-

OSA is defined by the presence of repetitive episodes(AHI>5) of upper airway obstruction during sleep. This study aims to assess the polysomnographic characteristics of OSA in young population(<50yrs age).

1.2     Methodology-

A prospective observational study of young population <50 years of age was conducted at department of pulmonary medicine, where all 36 participants underwent polysomnography. In this study we aim to outline the various variables, co-morbidities and AHI severity in this  population.

1.3     Results-

Out of 36 participants in our study population- 33 participants were found to have OSA. It comprised of 33%(n=12) females and 66%(n=24 )males. 55.5%(n=20) participants had severe AHI of which 85%(n=17) were males. 21%(n=25) of the population had an underlying obstructive airway disease. Smokers constituted almost 55%(n=19) of the cases and 65%(n=13) were males. ENT and thyroid disorders were found to be a common in severe and moderate AHI patients (16%,n=15 and 10%,n=9 ) prevailing more in females.

1.4     Conclusion-OSA in young population is an overlooked diagnosis. Average AHI for the study population  was (42.525). Overall, males (66%, n=24) were more prone to develop OSA in young. Female participants reported increased incidence of Asthma, ENT symptoms and hypothyroidism: when compared to men in the same subset. Smoking (55%,n=20) was found to be an independent risk factor for OSA prevalence as well as severity. Chest wall disorders and underlying obstructive airway disease (21%, n=19) predisposed the subjects to develop the condition.
