The purpose of this review is to summarize the peer-reviewed literature in relation to sunlight exposure assessment and the validity of using sunlight exposure questionnaires to quantify vitamin D status. There is greater variability in personal ultraviolet (UV) light exposure as the result of personal behavior than as the result of ambient UV light exposure. Although statistically significant, the correlation coefficients for the relation between personal report of sun exposure and ambient UV light measured by dosimetry (assessment of radiation dose) are relatively low. Moreover, the few studies to assess the relation between sunlight measures and serum 25-hydroxyvitamin D show low correlations. These low correlations may not be surprising given that personal factors like melanin content in skin and age also influence cutaneous synthesis of vitamin D. In summary, sunlight exposure questionnaires currently provide imprecise estimates of vitamin D status. Research should be directed to develop more objective, nonintrusive, and economical measures of sunlight exposure to quantify personal vitamin D status.

本综述的目的是总结与阳光暴露评估有关的同行评审文献,以及使用阳光暴露问卷量化维生素d状态的有效性。由于个人行为的结果,个人紫外线 (UV) 光暴露比环境紫外线暴露的结果具有更大的可变性。尽管具有统计学意义,但通过剂量测定法 (辐射剂量评估) 测量的个人日晒报告与环境紫外线之间关系的相关系数相对较低。此外,评估阳光测量与血清25-羟基维生素d之间关系的研究很少,但相关性较低。鉴于皮肤和年龄中的黑色素含量等个人因素也会影响皮肤维生素d的合成,因此这些低相关性可能不足为奇。总之,阳光暴露问卷目前提供了不精确的维生素d状况估计。应该进行研究,以开发更客观,非侵入性和经济的日光照射措施,以量化个人维生素d的状况。
