Data from the 1996 National Survey on Sun Exposure & Protective Behaviors (4,023 respondents) were analyzed to identify independent predictors of sunburn among adult Canadians.
Multivariate models predicting sunburn odds were developed using unconditional logistic regression. Backward elimination model selection was used to identify independent predictors of sunburn.
Nonbehavioral characteristics found to predict sunburn were younger age, male sex, light skin color, nonblack hair color, and birthplace in North America or Europe. Behavioral predictors of sunburn included high awareness of the UV Index, working outdoors in the summer, longer leisure time in the sun, forgetfulness about protecting oneself from the sun, and seeking a tan. Sun avoidance between 11 AM and 4 PM was associated with lower odds of sunburn, while seeking shade when outside and use of protective clothing showed nonsignificant associations with lower sunburn odds. Sunscreen use was found to have a nonsignificant positive association with sunburn.
These findings highlight risk factors to be considered in the targeting of sunburn reduction strategies to high-risk groups and suggest that sun avoidance, seeking shade, and use of protective clothing may be effective in preventing sunburn.
对1996年全国阳光暴露与防护行为调查（4023名受访者）的数据进行分析，以确定成年加拿大人晒伤的独立预测因素。
使用无条件逻辑回归建立预测晒伤几率的多变量模型。采用向后消除模型选择法来确定晒伤的独立预测因素。
发现可预测晒伤的非行为特征包括年龄较小、男性、浅肤色、非黑色头发颜色以及在北美或欧洲出生。晒伤的行为预测因素包括对紫外线指数的高度认知、夏季户外工作、在阳光下休闲时间较长、忘记采取防晒措施以及追求晒黑。上午11点至下午4点避免晒太阳与较低的晒伤几率相关，而在户外时寻找阴凉处和使用防护服与较低的晒伤几率之间的关联不显著。发现使用防晒霜与晒伤之间存在不显著的正相关。
这些发现突出了在针对高危人群制定减少晒伤策略时应考虑的风险因素，并表明避免晒太阳、寻找阴凉处和使用防护服可能有效地预防晒伤。
