Abstract

Objective To analyze the influencing factors of acute mountain sickness（AMS） in young male athletes who had moved to high-altitude areas and then trained at even higher altitudes. Methods A total of 245 245 young male athletes who had moved to an altitude of 3200 meters were analyzed. The incidence of AMS was observed after one week of training at an altitude of 4200 meters. The difference in various indicators between the AMS group and the non -AMS group were compared, and the influencing factors of AMS were explored. Results Among the 245 young male athletes, 26 experienced AMS symptom score ≥5 points, accounting for 10. 6%. There was no statistical difference in age, smoking history, or body mass index （BMI）between the two groups. The exposure time of high altitude and the arterial oxygen saturation in AMS group was significantly lower. The Self-Rating Depression Scale (SDS) score and Self-Rating Anxiety Scale (SAS) score were significantly higher in the AMS group than those in the non-AMS group. The score of the Connor-Davidson Resilience Scale (CD-RISC) in the AMS group was significantly lower than that in the non-AMS group, with statistically significant differences (P < 0.05). Multivariate logistic regression analysis showed that the occurrence of AMS symptoms was related to high-altitude residence time, blood oxygen saturation, SDS score, and SAS score. Conclusions The incidence of AMS in young male athletes who have moved to an altitude of 3200 m and then trained at an altitude of 4200 m is relatively low. The occurrence of AMS symptoms is related to high-altitude residence time, blood oxygen saturation, SDS score and SAS score.
