Abstract
Objectives: The objectives of this study were to assess serum 25OHD level among healthy Saudi population of Qassim region, besides socio- demographic characters, dietary habits, sun exposure and common symptoms of vitamin D deficiency were also evaluated.
Subjects and Methods: One hundred and eighty healthy males and females subjects above the age of 18 years were randomly selected from five primary health care centers of Qassim region. A predesigned structured questionnaire was administered by the doctor working in Primary Health Care Center and blood sample was obtained for measuring vitamin D (serum 25 OHD) level. Vitamin D sufficiency was defined as serum level of 25 OHD 30ng/ ml or above. A level ranging 20 to 29 ng/ml was considered as vitamin D insufficiency, whereas below 20ng/ml as vitamin D deficiency.
Results: Out of 180 study participants, 51(28.3%) subjects were vitamin D deficient, 71 (39.4%) were vitamin insufficient and 58 (32.2%) had normal vitamin D level. Commonest symptom of vitamin D deficiency was bone pain (20%) and fatigue (11.1%).
Conclusion: Vitamin D inadequacy is a major public health problem in Saudi population. The prevalence of vitamin D deficiency/ insufficiency among healthy Saudi population residing in Qassim region is 67.8%. If the issue is not urgently addressed it could lead to serious health consequences.
