摘　　要：目的观察使用防晒霜和采取衣物遮挡不同防晒方式对日光紫外线的防护效果,为指导公众科学防晒提供数据支持。方法选择78名受试者,按意愿分为使用防晒霜组(62人)和对照组(16人)。通过观察受试者9 d的日光暴露前后各部位皮肤颜色的变化,评价不同防晒方式的防护效果。结果与各自日光暴露前相比,两组受试者暴露后的左、右脸颊皮肤颜色指标ITA°均降低(P<0.05),右上臂皮肤颜色指标ITA°军训前后没有差异(P>0.05)。日光暴露前后,防晒霜使用组受试者左、右脸颊皮肤颜色变化指标ITA°差值均小于对照组(P<0.05)。日光暴露前后,两组受试者右上臂皮肤颜色变化指标ITA°差值均小于各自右脸颊的皮肤。结论在实际日常情况下,使用防晒霜方式仅能减缓但无法避免肤色变黑;衣物遮挡的防晒效果优于使用防晒霜。Objective To observe the protective effect of using sunscreen and covering with clothing against solar ultraviolet,and to provide a data support for guiding the public in with scientific sun protection.Methods Seventy-eight subjects were selected and divided by preference into sunscreen use group(n=62)and control group(n=16).The protective effect of different sun protection behaviors was evaluated by observing the changes in skin color at each site before and after 9 days of sunlight exposure.Results The skin color index individual typology angle(ITA°)at the left and right cheeks significantly decreased after sunlight exposure in both groups(P<0.05),and there was no significant change in ITA°at the right upper arm after military training(P>0.05).The change in ITA°at the left and right cheeks after sunlight exposure in the sunscreen use group was significantly smaller than that in the control group(P<0.05).The change in ITA°at the right upper arm after sunlight exposure was smaller than that at the right cheek in both groups.Conclusion In actual daily situations,the use of sunscreen only slows but does not prevent the darkening of the skin color;covering with clothing is better than using sunscreen for sun protection.
