Background: Although there are more than 200 peaks higher than 3000 m in the Taiwan Alps, no data on the incidence of acute mountain sickness (AMS) are available. This study investigated the incidence of AMS in Jade Mountain climbers. Methods: The study was performed at the entrance of Jade Mountain, the highest peak (3952 m) in Taiwan. A standardized form was used to collect information. All the recorders had previously been trained in the management of high altitude illness. The Lake Louise consensus was used for the diagnosis of AMS. Results: There were 93 trekkers (18 females and 71 males) who were surveyed. Four records with incomplete data were excluded, leaving 89 records for analysis. The ages ranged from 20-68 yr, with an average age of 41.1 ± 11.2 SD. All subjects had a home residence below 1 km. The most common high altitude symptoms were headaches. Some 25 trekkers (27%) met the diagnoses of AMS. The most common site of the AMS cases feeling their worst symptoms was in the midway overnight hut, and not on the summit. The lower the O2 saturation recorded at the entrance (2659 m) of Jade Mountain, the higher the score of the Lake Louise Acute Mountain Sickness Score (LLAMSS). Conclusions: Acute mountain sickness is a common problem in Taiwan summit climbers. In our study, 27% of the Jade Mountain trekkers met the diagnosis of AMS; however, the incidence of AMS was lower than that of other studies at similar altitudes.
