Assessment of the relationship between Vitamin D level and non-specific musculoskeletal system pain: A Multicenter Retrospective Study (Stroke Study Group) [Vitamin D Düzeyi ile Non-spesifik Kas İskelet Sistemi Ağrıları Arasındaki İlişkinin Değerlendirilmesi: Çok Merkezli Retrospektif Bir Çalışma (İnme Çalışma Grubu)]

Objective: In this study, it was aimed to evaluate the relationship between vitamin D level and pain severity, localization and duration in atients with non-specific musculoskeletal pain.Materials and Methods: Patients who applied to physical medicine and rehabilitation outpatient clinics due to non-specific muscle pain in 19centers in Turkey were retrospectively screened. Three thousand four hundred fourpatients were included in the study, whose pain level wasdetermined by visual analog scale (VAS) and the painful region, duration of pain and vitamin D level were reached. D group was found to beD deficient (group 1) when 25 (OH)D level was 20 ng/mL or less and group D 2 (vitamin D deficiency) was higher than 30 ng/mL (group 3).The groups were compared in terms of pain duration, localization and severity. In addition, the correlations of pain localization, severity andduration with vitamin D levels were examined.Results: D vitamin deficiency was detected in 2202 (70.9%) of 3 thousand four hundred and four registered patients, and it was foundthat vitamin D deficiency in 516 (16.6%) and normal vitamin D in 386 (12.4%). The groups were similar in terms of age, body mass index,income level, duration of complaint, education level, family type and working status between groups in terms of VAS, pain localization and duration scores (p>0.05). Conclusion: Our study shows that vitamin D deficiency in patients with nonspecific musculoskeletal pain is not associated with the severity and duration of pain. © Copyright 2017 by the Turkish Osteoporosis Society
