Acute mountain sickness (AMS) is commonly found among people traveling above 2500 m. We investigated whether the occurrence of AMS is related to differences in individual physical fitness and BMI in subjects 11-13 years of age.
This study was conducted at Xue Mountain, Taiwan (elevation of 3886 m) between June 13, 2011 and June 17, 2011. Subjects were asked to ascend from Taipei City (25 m) to the summit (3886 m) over 3 days and 2 nights. Gender, age, weight, height, and fitness index (determined using a 3-minute step test) were recorded at sea level before ascent. The Lake Louise AMS score was used to record symptoms and diagnose AMS.
A total of 179 subjects (mean age: 11.8 years; 102 males, 77 females) were included in the analysis. A total of 44.7% of subjects were diagnosed with AMS. Male gender (p = 0.004) and elevated body mass index (BMI) (p < 0.001) were each associated with the development of AMS. However the physical fitness index was comparable in subjects with and without AMS (67.8 ± 10.1 vs. 68.0 ± 9.3, p = 0.9).
This study shows that both BMI and male gender were associated with the development of AMS in 11-13 year old children. Physical fitness was not associated with the occurrence of AMS.
急性高原病（AMS）常见于海拔2500米以上旅行的人群中。我们调查了11至13岁受试者中AMS的发生是否与个体身体素质和体重指数（BMI）的差异有关。
本研究于2011年6月13日至2011年6月17日在台湾雪山（海拔3886米）进行。受试者被要求在3天2夜内从台北市（海拔25米）攀登至山顶（海拔3886米）。在登山前海平面高度记录性别、年龄、体重、身高和身体素质指数（通过3分钟台阶试验测定）。使用路易斯湖AMS评分记录症状并诊断AMS。
共有179名受试者（平均年龄：11.8岁；男性102名，女性77名）纳入分析。共有44.7%的受试者被诊断为AMS。男性（p = 0.004）和体重指数升高（BMI）（p < 0.001）均与AMS的发生有关。然而，有AMS和无AMS的受试者身体素质指数相当（67.8±10.1对68.0±9.3，p = 0.9）。
本研究表明，BMI和男性性别均与11至13岁儿童AMS的发生有关。身体素质与AMS的发生无关。
