Vitamin D Deficiency and Musculoskeletal Pain: Prevalence and Risk Factors
Vitamin D deficiency is highly prevalent among individuals with musculoskeletal pain across various populations, including adolescents, adults, and the elderly. Studies consistently report a high rate of vitamin D deficiency in patients presenting with chronic, non-specific, or widespread musculoskeletal pain, with prevalence rates ranging from 59% to over 90% in different cohorts Nilachandra2016Çidem2017Sertpoyraz2019+3 MORE. Risk factors for deficiency include limited sun exposure, older age, female sex, and certain seasons, particularly winter and early spring Çidem2017Sertpoyraz2019Heath2006.
Association Between Vitamin D Deficiency and Musculoskeletal Pain
Research shows a significant association between vitamin D deficiency and musculoskeletal pain, especially chronic widespread pain. Large-scale studies indicate that while vitamin D deficiency is not a strong independent predictor of regional musculoskeletal pain after adjusting for confounding factors, severe deficiency remains linked to chronic widespread pain Xie2024Yılmaz2017. This relationship is observed in both general and specific populations, such as elderly women and healthcare workers Sertpoyraz2019Elsheikh2018.
Clinical Manifestations: Pain, Muscle Weakness, and Functional Impact
Vitamin D deficiency can manifest as muscle aches, non-specific musculoskeletal pain, and muscle weakness. These symptoms are commonly reported in both adolescents and adults with low vitamin D levels Nilachandra2016Nagarjunakonda2017Heath2006. In elderly women, deficiency is associated with pain predominantly in the lower and upper back, as well as reduced functional capacity and increased risk of falls Sertpoyraz2019Heath2006. The presence of vitamin D receptors in muscle and nervous tissue supports the biological plausibility of these symptoms Yılmaz2017Nagarjunakonda2017Heath2006.
Response to Vitamin D Supplementation
Several studies report that vitamin D supplementation can lead to significant improvement in musculoskeletal pain for many patients with deficiency Nilachandra2016Heath2006Abbasi2012. However, not all patients respond equally, and the degree of pain relief may depend on achieving sufficient serum vitamin D levels. Non-responders may have other underlying causes for their pain or may not reach adequate vitamin D concentrations despite supplementation Nilachandra2016Abbasi2012.
Confounding Factors and Limitations
While the association between vitamin D deficiency and musculoskeletal pain is well-documented, pain is often multifactorial. Studies highlight that factors such as psychological health, comorbidities, and lifestyle also play important roles in pain perception and persistence Xie2024Nilachandra2016. Therefore, vitamin D deficiency should be considered as one of several possible contributors to musculoskeletal pain, rather than the sole cause.
Recommendations for Clinical Practice
Given the high prevalence of vitamin D deficiency in patients with musculoskeletal pain, routine assessment of vitamin D status is recommended, especially in at-risk groups such as the elderly, women, and those with limited sun exposure Çidem2017Sertpoyraz2019Heath2006+1 MORE. Supplementation should be considered for those found to be deficient, with monitoring to ensure adequate serum levels are achieved Heath2006Abbasi2012.
Conclusion
Vitamin D deficiency is common among individuals with musculoskeletal pain and is particularly associated with chronic widespread pain and muscle weakness. While supplementation can improve symptoms in many cases, musculoskeletal pain is often influenced by multiple factors. Assessing and correcting vitamin D deficiency should be part of a comprehensive approach to managing musculoskeletal pain, especially in high-risk populations Xie2024Nilachandra2016Yılmaz2017+7 MORE.
