高原紫外线辐射对执勤官兵皮肤损伤的调查

目的 探讨高原紫外线对人体皮肤的影响及皮损的临床表现。方法 由专业人员在海拔3700 ~ 4786 m武警部队执勤官兵中随机调查1286例，详细记录官兵一般情况、高原入伍时间、累积日照时数及皮肤损伤情况，依据标准做出疾病分类分度诊断，最后进行统计学分析。结果 1286例执勤官兵，皮肤损伤率高达67.5%，其中晒黑798例，占调查对象的62.05%；光老化240例，占18.66%；多形性日光疹176例，占13.69%；晒伤171例，占13.30%。有213例合并2种皮肤损伤，152例合并3种皮肤损伤。晒黑、多形性日光疹和光老化患病率随着执勤官兵高原入伍时间延长而增高，随着累积日照时数增多而增高；晒伤多发生于初上高原的新兵，患病率则随着高原入伍时间延长而降低，随着累积日照时数增多而降低。结论 高原紫外线辐射对执勤官兵皮肤损伤极其严重，亟待寻找有效的防治方法。

Skin damage induced by ultraviolet radiation in high altitude: a survey in officers and soldiers

Objective To characterize the skin damage induced by ultraviolet radiation in officers was observed in 67.5% of the 1286 officers and soldiers:tanning in 62.05%(798/1286),photoaging in 18.66%(240/1286),polymorphous light eruption in 13.69%(176/1286)and sunbum in 13.30%(171/1286).Two hundred and thirteen subjects each had two kinds of skin amage,and 152 subjects each had three kinds of skin damage.With the time of being in the army and cumulative sun-exposure period,the prevalence of tanning,photoaging and polymorphous light eruption increased,while the prevalence of sunburn decreased.Sunburn mostly occurred in newly assigned soldiers.Conclusions The condition of skin damage nduced by ltraviolet radiation iS severe in officers and soldiers working in high altitude,and effective measures are warranted for the prevention and treatment of the skin damage.
