The Influence of Work Environment on Vitamin D Levels A among Radiologists in Jeddah and Yanbu-Saudi Arabia: A Comparative Study

Objectives: The aims of the study were to compare level of vitamin D deficiency between radiologists and a control group of non-radiologists. A dark, daylight-deprived work environment may increase the risk for radiologists having vitamin D deficiency. Materials and Methods: A comparative study containing a total of 66 participants divided into two groups (radiologist group) and (non radiologist group). This study was done in Jeddah and Yanbu industrial city. Result: The study revealed that the distribution of the Non-Radiologist according to vitamin D level signified as Normal level, Deficiency, severe Deficiency; 91.7 %, 41.3 % and 37.5 %respectively. the distribution of Radiologist according to vitamin D level signified as Normal level, Deficiency, severe Deficiency; 8.3 %, 58.7 % and 62.5 %respectively. A comparison between females and males radiologists on their vitamin D levels, Females radiologists were 21 participants, while the males radiologists were only 12 participants. It reveals 5 participants of Females suffer from severe vitamin D deficiency ( less than 10 Ng/ml) by a percentage of 15.1 %, while in males were 0 %. and 15 of females had vitamin D deficiency ( 10-29 Ng/ml) by a percentage of 45.4 %, while in males vitamin D deficiency were 36.4 %, and 3.0 % of females were normal (30-100 Ng/ml), while it was 0 % in males. Increasing of age increases the risk of vitamin D deficiency, radiologists who are age between (18-29) only 3.0 % of them had severe vitamin D deficiency ( less than 10 Ng/ml), while radiologists age between ( 30-49) 12.1 % of them had severe vitamin D deficiency. Radiologists who works 12 hours a day has high severe vitamin D deficiency (
