BACKGROUND
Vitamin D deficiency has been identified as a major public health problem worldwide. Sunlight is the main source of vitamin D and its measurement using dosimeters is expensive and difficult for use in population-based studies. Hence, the aim of this study was to develop and validate questionnaires to assess sunlight exposure in healthy individuals residing in Karachi, Pakistan.
METHODS
Two questionnaires with seven important items for sunlight exposure assessment were developed. Fifty four healthy adults were enrolled based on their reported sunlight exposure (high = 17, moderate = 18, low = 19) from Aga Khan University, Karachi. Over four days, study participants were asked to wear a dosimeter between sunrise and sunset and report time spent and activities undertaken in the sun for questionnaire validation. Algorithm for item weightage was created as an average score based on ultraviolet B percentage received. Blood samples were obtained for serum vitamin D.
RESULTS
The mean time (minutes) spent in sun over 4 days (±SD) was 69.5 (±32) for low, 83.5 (±29.7) for moderate and 329 (±115) for high exposure group. The correlation between average time (minutes) spent in sun over 4 days and mean change in absorbance of UV dosimeters for 4 days was 0.60 (p < 0.01). Correlation between average score and vitamin D levels was found to be 0.36 (p = 0.01) for short term questionnaire score, 0.43 (p = 0.01) for long term questionnaire score in summers and 0.48 (p = 0.01) in winters.
CONCLUSIONS
The sunlight exposure measurement questionnaires were valid tools for use in large epidemiological studies to quantify sunlight exposure.
背景
维生素 D 缺乏已被确定为全球范围内的一个主要公共卫生问题。阳光是维生素 D 的主要来源，使用剂量仪测量其含量既昂贵又难以用于基于人群的研究。因此，本研究旨在开发和验证评估居住在巴基斯坦卡拉奇的健康个体阳光暴露的问卷。
方法
开发了两个包含评估阳光暴露的七个重要项目的问卷。根据阿迦汗大学卡拉奇分校报告的阳光暴露情况（高暴露=17 人，中暴露=18 人，低暴露=19 人），招募了 54 名健康成年人。在四天内，研究参与者被要求在日出和日落之间佩戴剂量仪，并报告在阳光下度过的时间和进行的活动，以验证问卷。根据紫外线 B 百分比创建了项目权重算法。采集血清维生素 D 样本。
结果
在 4 天内（±SD），低暴露组每天平均在阳光下度过的时间（分钟）为 69.5（±32），中暴露组为 83.5（±29.7），高暴露组为 329（±115）。在 4 天内平均每天在阳光下度过的时间（分钟）与紫外线剂量仪平均吸收变化之间的相关性为 0.60（p<0.01）。发现短期问卷评分与维生素 D 水平之间的相关性为 0.36（p=0.01），夏季长期问卷评分的相关性为 0.43（p=0.01），冬季的相关性为 0.48（p=0.01）。
结论
阳光暴露测量问卷是在大型流行病学研究中用于量化阳光暴露的有效工具。
