Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Extreme changes in the Antarctic environment can cause emotional and autonomic dysfunction. In this study, volunteers from the Antarctica stations in China provided scale scores and heart rate variability (HRV) data, which were used to assess the autonomic nervous system. Enroll twenty-two members from Zhongshan Station and the Great Wall Station who are overwintering. Using the Generalized Anxiety Disorder (GAD-7) scale, the Patient Health Questionnaire-9 (PHQ-9) scale, and the SF-36 quality of life scale to evaluate the individual's general physical and mental health. Analyze HRV and other associated parameters.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study was a prospective observational study. We selected 12 members in Antarctica at the Great Wall Station of the 37th Chinese Antarctic Scientific Expedition (CSEA) from March 2021 to April 2022. And 10 members in Antarctica at Zhongshan Station in the 38th CSEA from December 2021 to April 2023. There were 22 members in total. Team members are volunteers selected through interviews, followed by detailed medical and psychological examinations, and are made up of scientific and logistical staff. According to the different work content of the scientific expedition team members, and taking the average outdoor working time of 2 hours/day as the node, the scientific expedition team members are divided into outdoor groups (n=12) and indoor groups (n=10). Participants will be assessed on the day they enter the Antarctic station and leave. Assessments include HRV, SF-36 quality of life questionnaire, Patient Health Questionnaire-9 (PHQ-9) scale and Generalized Anxiety Disorder (GAD-7) scale. This study approved by the local ethics committee of Shanghai Tenth People's Hospital, and conformed to the Declaration of Helsinki and its later amendments.
