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.

Condition or disease Intervention/treatment
OSA Age Problem Other: Age Other: OSA

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.

Group/Cohort Intervention/treatment
Young adult, without OSAS
20<=Age<40 years old, apnea-hypopnea index(AHI)<5
 Other: Age
Age<40 years old is chosen as the cutoff value.
Young adult, with OSAS
20<=Age<40 years old, AHI>=5
 Other: Age
Age<40 years old is chosen as the cutoff value.

Other: OSA
The diagnosis of OSA (obstructive sleep apnea) relies on polysomnographic data showing an apnea-hypopnea index at least 5/hr with compatible symptoms.
older adult, without OSAS
Age>=40 years old, AHI<5
older adult, with OSAS
Age>=40 years old, AHI>=5

Primary Outcome Measures :
  1. Apnea-hypopnea index(AHI) [ Time Frame: through study completion, an average of 1 year ]
    Counts of apnea/hypopnea events per hour


Secondary Outcome Measures :
  1. Body mass index(BMI) [ Time Frame: through study completion, an average of 1 year ]
    The body mass divided by the square of the body height.

  2. Posterior airway space (PAS) [ Time Frame: through study completion, an average of 1 year ]
    The diameter from supramentale to gonion.

  3. Number of participants with comorbidities [ Time Frame: through study completion, an average of 1 year ]
    Self-reported comorbidities including cardiovascular disease, stroke, hypertension, diabetes mellitus, hyperlipidemia, lung disease, anxiety, depression.

  4. Sleep efficiency [ Time Frame: through study completion, an average of 1 year ]
    The ratio of the total time spent asleep (total sleep time) in a night compared to the total amount of time spent in bed.

  5. arousal index [ Time Frame: through study completion, an average of 1 year ]
    The number of arousals and awakenings as a frequency per hour of sleep.

  6. oxygen desaturation index [ Time Frame: through study completion, an average of 1 year ]
    The number of times per hour of sleep that the blood's oxygen level drop by 4% from baseline.
