Age Problem, OSA
Conditions
Brief summary
By clinical record review, this retrospective study aims to compare the different age groups of patients with obstructive sleep apnea, who were diagnosed and treated in Taipei Veterans General Hospital, Taiwan.
Detailed description
This retrospective study aims to compare the characteristics of patients with obstructive sleep apnea (OSA). Patients with sleep problem and received a prior polysomnography at Taipei Veterans General Hospital during Jan. 1, 2016 to Dec. 31, 2017 will be enrolled. Obstructive sleep apnea (OSA) is defined by an apnea-hypopnea index(AHI) at least 5/hr with compatible symptoms. Their clinical record will be reviewed and data including demography, polysomnography, comorbidities and details related to upper airway structure will be collected. The charactereistics would be compared with Student's t tests, Mann-Whitney U tests, or Chi square tests if appropriated.
Interventions
OTHERAge
Age\<40 years old is chosen as the cutoff value.
OTHEROSA
The diagnosis of OSA (obstructive sleep apnea) relies on polysomnographic data showing an apnea-hypopnea index at least 5/hr with compatible symptoms.
