NCT06385782

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • changes in HRV

    Before and after the expedition to Antarctica, we conducted comparative analyses of HRV data.

    members in Antarctica at Zhongshan Station in the 38th CSEA from December 2021 to April 2023

Study Arms (2)

outdoor groups

Outdoor work time is more than 2 hours

Other: Antarctic environment

indoor groups

Outdoor work time is less than 2 hours

Other: Antarctic environment

Interventions

. 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.

Study Population

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.

You may qualify if:

  • Team members are volunteers selected through interviews, followed by detailed medical and psychological examinations, and are made up of scientific and logistical staff.

You may not qualify if:

  • People with physical or mental illness
