A total of 805 sunbathing Caucasians were interviewed about sunprotection behaviour and self-assessed burning tendency. Sixty-seven percent of the interviewed sunbathers used one or more sunscreen factors. Sunscreen-users and nonusers were exposed to the sun 206 min and 197 min (P = 0.186), respectively. The sunscreen users were exposed to a marginally higher UV dose than non-sunscreen users, 4.8 SED versus 4.5 SED (P = 0.0348). The rate of sunscreen users was significantly higher among subjects who stated that they always were sunburnt in the spring when not using a sunscreen than subjects who stated that they never were sunburnt in the spring when not using a sunscreen (P = 0.0001). However, when comparing subjects that always burn in the spring and subjects that never burn in the spring, we found no significant difference between level of the sun-protection factor (P = 0.11) nor the duration of sun exposure (P = 0.967), nor to which UV doses the subjects were exposed (P = 0,562). Furthermore we found that the interviewed sunbathers interpreted to "be sunburnt" as more severe than "to turn red". Public campaigns recommend the use of sun protection cream when sunbathing without using other sun protective strategies; however, the use of sun protection cream is inadequate among sunbathers. More education is required to persuade those with more sun-sensitive skin to use a higher protection-factor, to reduce sun exposure at times when UV radiation is most intense, and to reduce the duration of exposure.
共对805名进行日光浴的白种人就防晒行为和自我评估的晒伤倾向进行了访谈。67%的受访日光浴者使用了一种或多种防晒措施。使用防晒霜者和未使用者晒太阳的时间分别为206分钟和197分钟（P = 0.186）。使用防晒霜者所接受的紫外线剂量略高于未使用防晒霜者，分别为4.8个最小红斑量和4.5个最小红斑量（P = 0.0348）。在表示春天不使用防晒霜时总是会晒伤的受试者中，使用防晒霜者的比例显著高于表示春天不使用防晒霜时从不晒伤的受试者（P = 0.0001）。然而，在比较春天总是晒伤的受试者和春天从不晒伤的受试者时，我们发现防晒系数水平（P = 0.11）、晒太阳时长（P = 0.967）以及受试者所接受的紫外线剂量（P = 0.562）之间均无显著差异。此外，我们发现受访的日光浴者将“晒伤”理解为比“变红”更严重。公共宣传活动建议在进行日光浴时使用防晒霜，而不采用其他防晒策略；然而，日光浴者中防晒霜的使用并不充分。需要开展更多教育，以说服皮肤对阳光更敏感的人使用更高防晒系数的产品，在紫外线辐射最强时减少日晒时间，并缩短暴露时长。
