Differences by sex in actinic keratosis distribution

This study characterizes the distribution of actinic keratoses (AKs) by sex, age, and income using a cross-sectional chart review of 1,415 patients at the University of Cincinnati Medical Center (2012–2021). AK locations were recorded across nine body sites, revealing sex-specific patterns: men had more AKs on the scalp and ears, while women had more on the chest, back, abdomen, arms, and legs. Age and income quartiles showed no significant differences in AK distribution. Findings suggest behavioral and sociological factors influence UV exposure patterns, informing prevention efforts.

本研究通过对辛辛那提大学医学中心（2012-2021年）1,415名患者的横断面图表回顾，对日光性角化病（AK）的性别、年龄和收入分布进行了特征描述。AK的发生位置在九个身体部位被记录，揭示了性别特定的模式：男性在头皮和耳朵上出现更多AK，而女性则更多见于胸部、背部、腹部、手臂和腿部。年龄和收入四分位数在AK分布上未显示出显著差异。研究结果提示，行为和社会学因素影响着紫外线暴露模式，从而为预防工作提供了信息。
