Дефицит витамина D повышает риск развития фибромиалгии на 63%: результаты масштабного исследования

The study compared 561,418 adults with blood levels below 20 nanograms per milliliter (ng/mL) to an equal number of adults with levels of 30 ng/mL or higher. According to the report, researchers used de-identified electronic health records from the TriNetX Global Collaborative Network, matching participants for age, sex, and existing health conditions. People with low vitamin D levels (below 20 ng/mL) were 63% more likely to develop fibromyalgia than those with levels of 30 ng/mL or higher during the 10-year follow-up, according to the report. The study also found that individuals with low vitamin D had a 30% higher risk of receiving other chronic pain-related diagnoses. The study's first author, Dr. Elena Martinez, stated that the findings highlight a potential association but do not establish causation. The research team emphasized that the observational design can identify patterns in health records but cannot determine whether one factor caused the other. Although fibromyalgia cannot be diagnosed with a simple laboratory test, vitamin D has been described as integral to biological functions affecting every bodily system, according to a 2021 article by Mercola.com [1]. Pain is also recognized as an extremely common symptom of vitamin D deficiency, as noted by NaturalNews.com [2]. Researchers compared 561,418 adults with low vitamin D levels below 20 ng/mL against an equal number of adults whose levels were 30 ng/mL or higher, with the groups matched for age, sex, and existing health conditions, according to the report. Participants were followed for up to 10 years. Those with existing chronic pain diagnoses were excluded, and a one-year lag after the vitamin D test was applied before counting new fibromyalgia diagnoses, the report stated. This delay was designed to reduce the chance that undiagnosed cases were already affecting the results. The study relied on blood test data from the TriNetX network, a global collection of electronic health records, as stated in the methodology. Prior research using similar medical records approaches has documented that a large majority of patients with unexplained widespread pain were found to have deficient vitamin D levels, with more than 90 percent falling below normal in a Mayo Clinic study cited in "The Vitamin D Cure" [3]. The association strengthened as vitamin D levels fell. Adults over 65 with low levels had a 76% higher risk of fibromyalgia, and those with severe deficiency below 10 ng/mL had an 89% higher risk, the study reported. People whose low vitamin D was confirmed by two separate tests within a year had a 97% higher risk of developing the condition, according to the data. The authors noted that these results suggest a dose-response relationship, though they emphasized that observational data cannot prove causality. Previous metabolic research has established that vitamin D regulates pain-relevant pathways, with suboptimal levels linked to poor muscular function and increased fall risk in the elderly, according to Dr. Michael Holick's clinical text [4]. Because the study was observational, researchers could not rule out confounding factors such as physical activity, sun exposure, diet, or underlying health conditions that might influence both vitamin D levels and pain sensitivity, officials said. "These findings do not mean low vitamin D causes fibromyalgia," said co-author Dr. James Park in a statement. "Clinical trials are needed to determine whether correcting a deficiency changes risk." Vitamin D supports muscle and nervous system function and helps regulate inflammation and pain signaling, which may explain a biological link. An earlier study of Muslim women in Denmark with muscle pain consistent with fibromyalgia found that 88 percent were vitamin D deficient, as documented by Dr. Michael Holick [5]. However, researchers stated the proposed mechanism remains speculative until interventional studies are complete. The study does not recommend high-dose vitamin D without medical guidance. Experts advise consulting a doctor for a blood test if persistent fatigue or muscle aches are present. A blood test is considered essential for understanding current vitamin D status accurately, as emphasized in an interview on Brighteon.com [6]. Raising vitamin D levels can be done through foods, appropriate sun exposure, or supplements under medical supervision, as noted in the report. Expert sources note that most people misunderstand their risk because few foods contain therapeutic levels of vitamin D, a point made by Mercola.com [7]. The takeaway, as stated by the authors, is that low vitamin D is associated with higher fibromyalgia risk, but more research is needed to determine if improving levels can reduce that risk. Previous published work has already flagged vitamin D deficiency as a factor in approximately 200 million Americans, as reported in the press release for "The Vitamin D Solution" [8].
