Abbreviations: AMS, acute mountain sickness; BMI, body mass index. Data are presented as mean ± SD.
a n = number of children
b BMI = weight in kilograms divided by the square of the height in meters.
c In the menstruation section, the total population represents female subjects (86).
d Chi-square test was used to determine differences in categorical variable between the AMS and non-AMS groups. Mann-Whitney U-test was used to determine differences in numerical variables (body weight, body height, BMI) between the two groups.
¶ p < 0.05 indicates that AMS incidence was significantly higher in males than in females.
* p < 0.05 indicates a significant difference between the AMS and non-AMS groups.
