About this trial
The goal of this prospective cohort study is to study patients referred for sleep study by in-lab polysomnography in the Jordan University Hospital and the Jordan Hospital or with an at-home sleep study kit. The main aims are:
* To prospectively obtain demographic and clinical information of patients referred for a sleep study. * To determine the diagnostic value of facial discoloration as potential marker for obstructive sleep apnea to increase detection rate for the condition. * To establish a correlation between obstructive sleep apnea and vasovagal symptoms with resulting increased smoking tendency and study the effect of treatment on the disorders. * To determine the association between timing of appearance of obstructive sleep apnea symptoms and initiation of smoking.

Trial outcomes
Primary outcomes
Clinical association between obstructive sleep apnea and presence of facial pigmentation
Number of patients with a confirmed diagnosis of OSA by in-lab polysomnography or at-home sleep study and the presence of pigmentation on the face.
Clinical association between obstructive sleep apnea and severity of facial pigmentation
Grade of facial pigmentation in comparison with normal skin tone as low, moderate, or high in patients with a confirmed diagnosis of OSA by in-lab polysomnography or at-home sleep study.
Relation between obstructive sleep apnea and vasovagal symptoms
Presence of vasovagal symptoms in patients with a confirmed diagnosis of OSA by in-lab polysomnography or at-home sleep study.
Relation between obstructive sleep apnea and resulting smoking tendency due to vasovagal symptoms

Relation between obstructive sleep apnea and the effect of treatment on vasovagal symptoms
Presence of vasovagal symptoms after patients with a confirmed diagnosis of OSA by in-lab polysomnography or at-home sleep study receive treatment
Relation between obstructive sleep apnea and the effect of treatment on smoking habits
Frequency of smokers after patients with a confirmed diagnosis of OSA by in-lab polysomnography or at-home sleep study receive treatment
