Introduction: Deficiency of vitamin D is proved around the world. It's highly prevalent in the United States, Europe, Australia,
Turkey, India, and Lebanon. In Saudi Arabia the situation is no better. There is an increased prevalence of vitamin D deficiency
between Saudi Arabs (both males and females). Since UV light radiation is the ultimate source of vitamin D3, The correlation
between vitamin D deficiency and UV light exposure is very significant. Starting with this, Vitamin D deficiency is highly
prevalent in the medical community as they spend most of their times indoor with a limited exposure. Only few studies have
been done to evaluate the status of vitamin D in the medical students' and no studies regarding the evaluation of the daily
exposure to UV light among medical students.
Objective: This study is conducted in order to measure the amount of UV light the KSU female medical students are exposed
to during the day in the university campus. In addition, to determine the level of daily activities of KSU female medical
students relevant to UV light exposure.
Methodology: A cross sectional study was conducted at King Saud University, Collage of Medicine among 309 female medical
students representing different medical academic years. Questionnaire was distributed among the students and physical
measurement of UV light density was carried out. The data were collected by the investigators and entered in the database and
analyzed using the Statistical Package for Social Sciences (SPSS).
Result: The highest amount of UV radiation was found in the 5th year classroom which reached 700 μW/cm2. Third year
students have the highest level of UV exposure compared to other students (896.91±488.99). Eighty percent (80.2%) of the
participated students in our study claimed to have vitamin D deficiency. Sun exposure and consumption of vitamin D rich-diet
Conclusion: The findings of the present study call for action at the university level to increase female medical student exposure
to UV light by providing gardens where students can spend time in and increase the number of windows in each class. Also
increase the awareness of female medical students to the affect of their life style on their VD level. We also recommend supplying
the most favorable food with fortified vitamin D. We recommend similar study involving larger population sample which is
more representative considering gender variation and including doctors, inters and nurses. Also recommend similar study in
other work field with different life style to study the affect of their UV light exposure on their vitamin D level.
