About this study

Official title: Age and Sleep Apnea Syndrome: Clinical Features and Outcomes

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AgeOther

    Age<40 years old is chosen as the cutoff value.

  • OSAOther

    The diagnosis of OSA (obstructive sleep apnea) relies on polysomnographic data showing an apnea-hypopnea index at least 5/hr with compatible symptoms.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Apnea-hypopnea index(AHI)

    Counts of apnea/hypopnea events per hour

    Measured: through study completion, an average of 1 year

Secondary outcomes (6)
  1. Body mass index(BMI)

    The body mass divided by the square of the body height.

    Measured: through study completion, an average of 1 year

  2. Posterior airway space (PAS)

    The diameter from supramentale to gonion.

    Measured: through study completion, an average of 1 year

  3. Number of participants with comorbidities

    Self-reported comorbidities including cardiovascular disease, stroke, hypertension, diabetes mellitus, hyperlipidemia, lung disease, anxiety, depression.

    Measured: through study completion, an average of 1 year

  4. Sleep efficiency

    The ratio of the total time spent asleep (total sleep time) in a night compared to the total amount of time spent in bed.

    Measured: through study completion, an average of 1 year

  5. arousal index

    The number of arousals and awakenings as a frequency per hour of sleep.

    Measured: through study completion, an average of 1 year

  6. oxygen desaturation index

    The number of times per hour of sleep that the blood's oxygen level drop by 4% from baseline.

    Measured: through study completion, an average of 1 year
