Friction blisters are common among outdoor enthusiasts, yet their causes remain uncertain. This study aimed to compare foot hydration in long-distance hikers with and without blisters, and to assess variability based on age and sex. An observational case-control study involving 86 hikers was conducted. Skin hydration was measured using a corneometer on various foot zones. Data on blister count, footwear, sex, age, and temperature were recorded. The most hydrated zones were the digital area, forefoot, and heel. Higher hydration was found in the blister group (61.6%) compared to the control group (38.4%). A significant relationship between hydration and blisters was observed in the left foot (p = 0.032). Total foot hydration was higher in women (p = 0.007) and inversely related to age (r = -0.333; p = 0.002). Hydration values above 30.40 a.u. in the right foot and 27.37 a.u. in the left foot were linked to blisters with 80% sensitivity. This study highlights the variability in foot hydration and its relationship with blisters. The influence of age and wet socks underscores the complexity of blister formation, emphasizing the need for future research on effective prevention.
摩擦水疱在户外爱好者中很常见，但其成因仍不明确。本研究旨在比较有和没有水疱的长途徒步旅行者的足部水合情况，并评估基于年龄和性别的变异性。进行了一项涉及86名徒步旅行者的观察性病例对照研究。使用角质层水合测定仪在足部不同区域测量皮肤水合情况。记录水疱数量、鞋类、性别、年龄和温度等数据。水合程度最高的区域是趾部、前脚掌和脚跟。水疱组的水合程度较高（61.6%），而对照组为（38.4%）。在左足观察到水合与水疱之间存在显著关系（p = 0.032）。女性的足部总体水合程度较高（p = 0.007），且与年龄呈负相关（r = -0.333；p = 0.002）。右足水合值高于30.40任意单位和左足水合值高于27.37任意单位与水疱相关，敏感性为80%。本研究强调了足部水合的变异性及其与水疱的关系。年龄和湿袜子的影响突出了水疱形成的复杂性，强调了未来进行有效预防研究的必要性。
