Photosensitivity disorders involve an abnormal skin reaction to sunlight exposure and affect a substantial percentage of the population. No previous studies have directly compared lifestyle attributes between photosensitive and healthy individuals.
To assess the impact of photosensitivity on time spent outdoors in the U.K., holiday behaviour, use of sunscreens and vitamin D supplements, and employment status.
Questionnaires were completed by ambulant photosensitive and healthy adults aged 18-60 years residing in Greater Manchester.
Forty-five adults with moderate-severe photosensitivity and 124 healthy adults completed the questionnaire. This revealed that photosensitive subjects spent significantly less time outdoors in the U.K. on both summer weekdays (P < 0·01) and summer weekends (P < 0·0001) than healthy subjects, took fewer holidays per year (P < 0·05), and spent less time outdoors on a sunny holiday (P < 0·0001). They wore clothing that covered a wider skin area (P < 0·0001), and use of sunscreen was greater (both frequency of application and area covered) in the photosensitive group outside of holiday time (P < 0·0001), but not when on a sunny holiday, as healthy people increased their sunscreen use at this time. Despite the reduced sun exposure, photosensitive subjects were no more likely to take vitamin D supplements than healthy subjects were; they also exhibited a significantly higher rate of unemployment (P < 0·05).
Photosensitivity disorders negatively influence lifestyle including employment status; more attention is required to the socioeconomic impact of these conditions.
光感性疾病涉及到对阳光暴露的异常皮肤反应，影响了相当大比例的人群。以前没有研究直接比较过光感性和健康个体之间的生活方式特征。
评估光感性对英国户外活动时间、度假行为、防晒霜和维生素 D 补充剂使用以及就业状况的影响。
对居住在大曼彻斯特的 18-60 岁的门诊光感性和健康成年人进行问卷调查。
45 名中重度光感性成年人和 124 名健康成年人完成了问卷调查。结果表明，光感性患者在英国夏季工作日（P < 0·01）和夏季周末（P < 0·0001）的户外活动时间明显少于健康对照组，每年度假次数较少（P < 0·05），阳光明媚的度假日户外活动时间也较少（P < 0·0001）。他们穿着覆盖更大皮肤面积的衣服（P < 0·0001），在非度假时间，光感性组的防晒霜使用频率和覆盖面积均大于对照组（P < 0·0001），但在阳光明媚的度假日则不然，因为健康人此时会增加防晒霜的使用。尽管减少了阳光暴露，光感性患者服用维生素 D 补充剂的可能性并不比健康对照组高；他们的失业率也明显更高（P < 0·05）。
光感性疾病对包括就业状况在内的生活方式产生负面影响；需要更多关注这些疾病的社会经济影响。
