Abdominal Breathing for Depression, Anxiety, Heart Rate Variability in Obstructive Sleep Apnea Patients
Condition: Obstructive Sleep Apnea
MeSH terms: Apnea; Sleep Apnea Syndromes; Sleep Apnea, Obstructive; Depression
Study type: Interventional

Summary: 
      The research topic is to explore the effectiveness of abdominal breathing on improving of
      depression, anxiety, and heart rate variability in obstructive sleep apnea patients with
      depressive symptoms. This study method adopts an experimental research design and divided
      into experimental group and control group by random sampling. Experimental group receives
      abdominal breathing training, whereas control group without receiving abdominal breathing
      training.
    

Detailed description: 
      Obstructive Sleep Apnea (OSA) is a common chronic disease with frequent comorbidity of
      depression. When we use sedatives, antidepressants or hypnotics for the treatment of
      depression, these drugs may worsen symptoms of OSA leading to aggravation of original
      depressed moods. Therefore, the research topic is to explore the effectiveness of abdominal
      breathing on improving of depression, anxiety, and heart rate variability among obstructive
      sleep apnea patients with depressive symptoms. This study method adopts an experimental
      research design and divided into experimental group and control group by random sampling.
      Experimental group receives abdominal breathing training, whereas control group without
      receiving abdominal breathing training. The research is conducted with experimental and
      control groups. The effectiveness assessment will use the Beck Depression Inventory (BDI)
      Beck Anxiety Inventory (BAI) and check the heart rate variability (HRV). Both groups received
      the pre-test before the abdominal breathing training. The post-test was carried out at the
      fourth and eighth weeks of training. The experimental group is given abdominal breathing
      training for a total of 8 weeks, with the training in the hospital once a week, 15 minutes
      for each time, in combination with self-training at home under videos guidance for 10 minutes
      per day (10 minutes, for one time or several times accumulated) .The expected result is
      through abdominal breathing, the depression, anxiety, and heart rate variability of OSA
      patients with depressive symptoms can improve, and even with less use of medication.
    

Intervention name(s): Abdominal breathing training
Intervention type(s): Behavioral
Intervention description(s): In the sleep center, it is carried out in a one-on-one manner by the trainer. At home, self-training through abdominal breathing training videos (10 minutes per day, you can accumulate up to 10 minutes in divided doses)
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: This study method adopts an experimental research design and divided into experimental group and control group by random sampling. Experimental group receives abdominal breathing training, whereas control group without receiving abdominal breathing training.
