Is the patient-perceived impact of psoriatic arthritis a global concept? An international study in 13 Arab countries (TACTIC study).

The Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire, a recommended measure of patient-reported impact for psoriatic arthritis (PsA), was initially developed in Europe and may lack universal validity. Recognizing the need for a culturally appropriate tool for Arab patients, this study aimed to TranslAte, CulTurally adapt, and validate the PsAID in ArabIC (TACTIC). The PsAID-12 was translated into Arabic using a rigorous process of double translation, back-translation, and cognitive debriefing. The Arabic version was then validated through a study conducted in 13 Arab countries in 2022. Participants were consecutive literate adult patients diagnosed with PsA and fulfilling the CASPAR criteria. Collected data included PsAID-12, disease activity, and legacy patient-reported outcomes. Psychometric properties, such as internal consistency, construct validity, and test-retest reliability, were examined. Factors associated with high PsAID-12 total scores (> 4) were explored using multivariable binary logistic regression. A culturally adapted Arabic PsAID-12 questionnaire was achieved with minor rephrasing. The validation study included 554 patients from 13 countries (mean age 45 years, 59% females), with a mean PsAID score of 3.86 (SD 2.33). The Arabic PsAID-12 demonstrated excellent internal consistency (Cronbach's α = 0.95), and correlations with other measures ranged from 0.63 to 0.78. Test-retest reliability (N = 138 patients) was substantial (intraclass correlation coefficient, ICC 0.90 [0.86-0.93]; Cohen's kappa 0.80). Factors associated with a high PsAID score were disability (odds ratio, OR 3.15 [2.03-4.89]), depression (OR 1.56 [1.35-1.81]), widespread pain (OR 1.31 [1.12-1.53]), and disease activity (OR 1.29 [1.13-1.47]). Pain and fatigue were identified as the most impactful PsAID-12 domains for PsA patients. The Arabic PsAID is a valid and reliable measure that reflects the priorities of patients with PsA. PsAID scores correlated with disease activity and legacy outcome measures, as expected, indicating PsAID is a consistent measure of PsA impact across cultures. These findings highlight the potential of the Arabic PsAID in improving the care provided to Arabic-speaking patients worldwide.

Peripheral spondyloarthritis: What have we learned?

The peripheral spondyloarthritis (pSpA) entity remains poorly defined in comparison with axial SpA and psoriatic arthritis, as the clinical symptoms have low specificity, the biological markers are virtually lacking, and dedicated randomized controlled trials in this specific indication remain scarce. In addition, clinical similarities between pSpA and psoriatic arthritis (PsA) have been described, partly explained by a resemblance in the pathophysiology of both entities. Thus, diagnosing pSpA can be challenging because of the overlap with other entities and the absence of a specific test or imaging study that can definitively diagnose the condition. The aim of this review is to summarize the current understanding of pSpA, its epidemiology, physiopathology, clinical diagnosis, and classification criteria. In addition, we present patient-reported outcomes used in pSpA clinical studies, available evidence on therapies, and future directions.

What is the best referral strategy for axial spondyloarthritis? A prospective multicenter study in patients with suspicious chronic low back pain.

OBJECTIVE: To assess the value of referral strategies for axial spondyloarthritis (axSpA) in patients with suspicious chronic inflammatory low back pain (LBP), to estimate the value of inflammatory back pain (IBP) for referral, and to identify the predictive factors of the final diagnosis of axSpA in Middle Eastern Arab countries. METHODS: The study was multicentric, prospective, and conducted in LBP first-line clinics (rheumatology, internal, family medicine, orthopedic surgery, neurosurgery, and neurology). Consecutive adult patients aged under 45years were included in case of LBP suspicious of inflammatory nature according to the first-line physician. The rheumatologist's final diagnosis was the gold standard. The diagnostic properties of ten referral strategies (Brandt I, II, III, Hermann, RADAR, RADAR 2/3, MASTER, Braun, CAFASPA, and ASAS) and of IBP were calculated. A multivariable logistic regression identified the clinical predictive factors of axSpA. RESULTS: In 515 referred patients, axSpA was confirmed in 48%, refuted in 43%, and diagnosis remained inconclusive in 9%. The optimal referral strategy was the MASTER (PLR 3.3), which comprises IBP, good response to NSAIDs, positive HLA-B27, and SpA family history. Considering strategies without HLA-B27, the RADAR 2/3 had a PLR of 2.9 (IBP, good response to NSAIDs, any extra-musculoskeletal manifestation). The predictive factors for axSpA were MRI sacroiliitis, positive HLA-B27, high CRP, psoriasis, IBP, and longer symptom duration. Of all patients, 35% were self-referred, 16% were referred by primary care physicians, and 15% by neuro/orthopedic surgeons. CONCLUSION: Optimizing physicians' awareness of these clinical features may enhance referral in axSpA.

ASAS-EULAR recommendations for the management of axial spondyloarthritis: 2022 update.

OBJECTIVES: To update the Assessment of SpondyloArthritis international Society (ASAS)-EULAR recommendations for the management of axial spondyloarthritis (axSpA). METHODS: Following the EULAR Standardised Operating Procedures, two systematic literature reviews were conducted on non-pharmacological and pharmacological treatment of axSpA. In a task force meeting, the evidence was presented, discussed, and overarching principles and recommendations were updated, followed by voting. RESULTS: Five overarching principles and 15 recommendations with a focus on personalised medicine were agreed: eight remained unchanged from the previous recommendations; three with minor edits on nomenclature; two with relevant updates (#9, 12); two newly formulated (#10, 11). The first five recommendations focus on treatment target and monitoring, non-pharmacological management and non-steroidal anti-inflammatory drugs (NSAIDs) as first-choice pharmacological treatment. Recommendations 6-8 deal with analgesics and discourage long-term glucocorticoids and conventional synthetic disease-modifying antirheumatic drugs (DMARDs) for pure axial involvement. Recommendation 9 describes the indication of biological DMARDs (bDMARDs, that is, tumour necrosis factor inhibitors (TNFi), interleukin-17 inhibitors (IL-17i)) and targeted synthetic DMARDs (tsDMARDs, ie, Janus kinase inhibitors) for patients who have Ankylosing Spondylitis Disease Activity Score ≥2.1 and failed ≥2 NSAIDs and also have either elevated C reactive protein, MRI inflammation of sacroiliac joints or radiographic sacroiliitis. Current practice is to start a TNFi or IL-17i. Recommendation 10 addresses extramusculoskeletal manifestations with TNF monoclonal antibodies preferred for recurrent uveitis or inflammatory bowel disease, and IL-17i for significant psoriasis. Treatment failure should prompt re-evaluation of the diagnosis and consideration of the presence of comorbidities (#11). If active axSpA is confirmed, switching to another b/tsDMARD is recommended (#12). Tapering, rather than immediate discontinuation of a bDMARD, can be considered in patients in sustained remission (#13). The last recommendations (#14, 15) deal with surgery and spinal fractures. CONCLUSIONS: The 2022 ASAS-EULAR recommendations provide up-to-date guidance on the management of patients with axSpA.

Peripheral spondyloarthritis and psoriatic arthritis sine psoriase: are we dealing with semantics or clinically meaningful differences?

Diagnosing peripheral spondyloarthritis (pSpA) remains a significant challenge due to the lack of specific disease biomarkers and the overlap with other SpA subtypes, mainly psoriatic arthritis (PsA), which represents a diagnostic challenge particularly in the absence of skin psoriasis (PsA sine psoriase). This narrative review aimed to compare the epidemiology, genetic susceptibility, pathophysiology, classification criteria, disease phenotype and burden, and therapeutic guidelines between patients diagnosed with pSpA and those with PsA sine psoriase, to determine if the two entities should be considered jointly or distinctly. Globally, pSpA appears to be more inclusive compared with PsA sine psoriase Areas of similarities include age of onset, number of joints involved and prevalence of axial involvement. However, patients with pSpA have a male gender predominance, a higher prevalence of HLA-B27, enthesitis and involvement of large joints of the lower limbs, whereas patients with PsA sine psoriase have a higher prevalence HLA-Cw6, dactylitis and involvement of hand distal interphalangeal joints. Therefore, the difference between pSpA and PsA sine psoriase goes beyond semantics. The few dissimilarities should drive scientific efforts to reach a better characterisation of pSpA as an individual disease. Accordingly, randomised clinical trials should target patients with well-defined pSpA to identify effective therapies in this population.

Axial Disease in Psoriatic Arthritis: how can we Define it, and does it have an Impact on Treatment?

The Spondyloarthritis (SpA) represents a group of rheumatic inflammatory entities that share clinical, laboratory and imaging features, including Psoriatic Arthritis (PsA). Axial involvement may occur in up to 50% of patients with PsA (axPsA), causing inflammatory back pain, stiffness and changes on imaging. Whether axial SpA (axSpA) with psoriasis represents a distinct entity than axPsA is a matter of debate, since similarities and differences have been reported in terms of clinical expression and imaging. Patients with radiographically axPsA show lower prevalence of inflammatory b ack pain, lumbar and buttock pain in comparison with axSpA. In addition, imaging features differ between axPsA and axSpA, with less sacroiliitis in axPsA and more asymmetrical, chunky syndesmophytes which are predominant at the cervical spine location. Data on treatment efficacy and management recommendations are extrapolated from studies on axSpA, and only one published randomized clinical trial is dedicated specifically to axPsA to date.

Predictors of not Achieving Remission or Low Disease Activity in Axial Spondyloarthritis Patients from Middle Eastern Countries: A Prospective, Multicenter, Real-world Study.

Objectives: We sought to identify the predictors of not achieving remission or low disease activity (LDA) among axial spondyloarthritis (SpA) patients in four Middle Eastern countries. Methods: In this multicenter prospective real-world study, adult patients with axial SpA diagnosed clinically during January-June 2019, and who met the Assessment of SpondyloArthritis International Society classification criteria for axial SpA, were enrolled from the participating centers of four countries-Lebanon, Oman, Qatar, and the UAE. Patient demographics, disease history, comorbidities, treatment, and compliance data were obtained at baseline. The primary outcome was to determine the percentage of patients who did not achieve the clinical target of remission or LDA as indicated by Ankylosing Spondylitis Disease Activity Score-C-reactive protein (ASDAS-CRP) < 2.1 after a three-month follow-up period. Secondary outcomes were assessing the demographic and clinical characteristics of 'achievers' and 'non-achievers' and to study the predictors of ASDAS-CRP ≥ 2.1 in different clinical subsets. Results: The participants were 309 patients of both sexes, with a median age of 43 years. Women had a slight majority (53.7%). At the end of the study, 72.2% of patients achieved the clinical target of ASDAS-CRP < 2.1. Non-achievers were significantly more likely to have enthesitis, positive human leukocyte antigen B 27 status, psoriasis, peripheral involvement, fibromyalgia, and a lower score on Compliance Questionnaire for Rheumatology (CQR). Multiple regression analysis showed that low CQR score, enthesitis, psoriasis, and family history of SpA were independent predictors of ASDAS-CRP ≥ 2.1. Conclusions: This real-world study suggests that low compliance, positive human leukocyte antigen B 27 status, peripheral involvement, and presence of enthesitis, psoriasis, and fibromyalgia are predictors of not achieving remission or LDA in axial SpA patients.

What is peripheral spondyloarthritis? Identifying proportion, phenotype and burden in post hoc analysis of the ASAS-PerSpA study.

BACKGROUND: Little is known about the prevalence, phenotype, and burden of peripheral spondyloarthritis (pSpA). The objective of the study is to compare the phenotype and burden of disease of pure pSpA to that of pure psoriatic arthritis (PsA), pure axial SpA (axSpA), and combined forms of SpA. METHODS: This is a post hoc analysis of 4,185 patients from the cross-sectional ASAS-Peripheral involvement in SpA (PerSpA) study. Patients were approached in 2 ways: the first approach was based on the rheumatologist's diagnosis (diagnostic approach) and the second one was based on the fulfillment of ASAS or CASPAR classification criteria (classification criteria approach). Demographics, disease phenotype, and burden were compared among pure pSpA, PsA, axSpA, and the combined forms. FINDINGS: The proportion of pSpA was 31.5% of SpA using the classification criteria approach and 10.3% using the diagnostic approach. pSpA was pure (i.e. without axSpA or PsA) in 16.8% of pSpA using the criteria, and in 62.3% using the diagnostic approach. Using classification criteria and diagnostic approach, respectively, pure pSpA patients had a high prevalence of peripheral joint disease (86 and 96%), synovitis (76 and 91%), and enthesitis (57 and 55%), a positive HLA-B27 in 65 and 59%, a high C-Reactive Protein level in 51% and inflammatory back pain in 52 and 42%. However, compared to pure PsA and pure axSpA, they had a significantly higher disease burden, but lower use of biologics using both approaches. INTERPRETATION: The proportion of pSpA varies when using the classification criteria or the diagnostic approach. pSpA occurred in a pure form less frequently than PsA and axSpA and had intermediate features but a higher disease burden. FUNDING: The PerSpA main study has been conducted under the umbrella of ASAS thanks to unrestricted grants from PFIZER, LILLY, ABBVIE, NOVARTIS, UCB, JANSSEN, MERCK.

Root joint involvement in spondyloarthritis: a post hoc analysis from the international ASAS-PerSpA study.

OBJECTIVES: The primary objective was to compare the clinical characteristics of SpA patients with and without root joint disease (RJD+ and RJD-). The secondary objectives were to compare the prevalence of RJD across various SpA subtypes and in different world regions, and to compare the SpA axial severity and SpA burden between RJD+ and RJD-. METHODS: This is a post hoc analysis of the Assessment of Spondyloarthritis International Society PerSpA study (PERipheral involvement in SpondyloArthritis), which included 4465 patients with SpA [axial (axSpA), peripheral (pSpA), PsA, IBD, reactive and juvenile] according to the rheumatologist's diagnosis. RJD was defined as the 'ever' presence of hip or shoulder involvement related to SpA, according to the rheumatologist. Patient characteristics were compared between RJD+ and RJD-. Multivariable stepwise binary logistic regression analyses were conducted to identify factors associated with 'RJD', 'hip' and 'shoulder' involvement. RESULTS: RJD was significantly associated with the SpA main diagnosis (highest in pSpA), a higher prevalence of HLA-B27 positivity, enthesitis, tender and swollen joints, CRP, conventional synthetic DMARDs, loss of lumbar lordosis and occiput-wall distance >0. RJD was more prevalent in Asia, and occurred in 1503 patients (33.7%), with more hip (24.2%) than shoulder (13.2%) involvement. Hip involvement had a distinct phenotype, similar to axSpA (including younger age at onset, HLA-B27 positivity), whereas shoulder involvement was associated with features of pSpA (including older age at onset). CONCLUSION: RJD+ SpA patients had a distinctive clinical phenotype compared with RJD-. Hip involvement, based on the rheumatologist's diagnosis, was more prevalent than shoulder involvement and was clinically distinct.

Individual-level and country-level socio-economic factors and health outcomes in spondyloarthritis: analysis of the ASAS-perSpA study.

OBJECTIVES: The aim of this study was to investigate the association between individual-level and country-level socio-economic (SE) factors and health outcomes across SpA phenotypes. METHODS: Patients with axial SpA (axSpA), peripheral SpA (pSpA) or PsA from the ASAS-perSpA study (in 23 countries) were included. The effect of individual-level (age, gender, education and marital status) and country-level [e.g. Gross Domestic Product (GDP)] SE factors on health outcomes [Ankylosing Spondylitis Disease Activity Score (ASDAS) ≥ 2.1, ASDAS, BASFI, fatigue and the Assessment of SpondyloArthritis international Society Health Index (ASAS-HI)] was assessed in mixed-effects models adjusted for potential confounders. Interactions between SE factors and disease phenotype were tested. A mediation analysis was conducted to explore whether the impact of country-level SE factors on ASDAS was mediated through biologic/targeted synthetic (b/ts) DMARD uptake. RESULTS: In total, 4185 patients (61% males, mean age 45) were included (65% axSpA, 25% PsA, 10% pSpA). Female gender [ß= 0.14 (95% CI: 0.06, 0.23)], lower educational level [ß = 0.35 (0.25, 0.45)) and single marital status [ß = 0.09 (0.01, 0.17)] were associated with higher ASDAS. Living in lower GDP countries was also associated with higher ASDAS [ß = 0.39 (0.16, 0.63)], and 7% of this association was mediated by b/tsDMARD uptake. Higher BASFI was similarly associated with female gender, lower education and living alone, without the effect of country-level SE factors. Female gender and lower educational level were associated with worse ASAS-HI, while more fatigue was associated with female gender and higher country-level SE factors [lower GDP, ß = -0.46 (-0.89 to -0.04)]. No differences across disease phenotypes were found. CONCLUSIONS: Our study shows country-driven variations in health outcomes in SpA, independently influenced by individual-level and country-level SE factors and without differences across disease phenotypes.

Identification of clinical phenotypes of peripheral involvement in patients with spondyloarthritis, including psoriatic arthritis: a cluster analysis in the worldwide ASAS-PerSpA study.

OBJECTIVE: To identify clusters of peripheral involvement according to the specific location of peripheral manifestations (ie, arthritis, enthesitis and dactylitis) in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), and to evaluate whether these clusters correspond with the clinical diagnosis of a rheumatologist. METHODS: Cross-sectional study with 24 participating countries. Consecutive patients diagnosed by their rheumatologist as PsA, axial SpA or peripheral SpA were enrolled. Four different cluster analyses were conducted: one using information on the specific location from all the peripheral manifestations, and a cluster analysis for each peripheral manifestation, separately. Multiple correspondence analyses and k-means clustering methods were used. Distribution of peripheral manifestations and clinical characteristics were compared across the different clusters. RESULTS: The different cluster analyses performed in the 4465 patients clearly distinguished a predominantly axial phenotype (cluster 1) and a predominantly peripheral phenotype (cluster 2). In the predominantly axial phenotype, hip involvement and lower limb large joint arthritis, heel enthesitis and lack of dactylitis were more prevalent. In the predominantly peripheral phenotype, different subgroups were distinguished based on the type and location of peripheral involvement: a predominantly involvement of upper versus lower limbs joints, a predominantly axial enthesitis versus peripheral enthesitis, and predominantly finger versus toe involvement in dactylitis. A poor agreement between the clusters and the rheumatologist's diagnosis as well as with the classification criteria was found. CONCLUSION: These results suggest the presence of two main phenotypes (predominantly axial and predominantly peripheral) based on the presence and location of the peripheral manifestations.

Prevalence and distribution of peripheral musculoskeletal manifestations in spondyloarthritis including psoriatic arthritis: results of the worldwide, cross-sectional ASAS-PerSpA study.

OBJECTIVES: To characterise peripheral musculoskeletal involvement in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), across the world. METHODS: Cross-sectional study with 24 participating countries. Patients with a diagnosis of axial SpA (axSpA), peripheral SpA (pSpA) or PsA according to their rheumatologist were included. The investigators were asked which diagnosis out of a list of six (axSpA, PsA, pSpA, inflammatory bowel disease-associated SpA, reactive arthritis or juvenile SpA (Juv-SpA)) fitted the patient best. Peripheral manifestations (ie, peripheral joint disease, enthesitis, dactylitis and root joint disease), their localisation and treatments were evaluated. RESULTS: A total of 4465 patients were included (61% men, mean age 44.5 years) from four geographic areas: Latin America (n=538), Europe plus North America (n=1677), Asia (n=975) and the Middle East plus North Africa (n=1275). Of those, 78% had ever suffered from at least one peripheral musculoskeletal manifestation; 57% had peripheral joint disease, 44% had enthesitis and 15% had dactylitis. Latin American had far more often peripheral joint disease (80%) than patients from other areas. Patients with PsA had predominantly upper limb and small joint involvement (52%).Hip and shoulder involvement was found in 34% of patients. The prevalence of enthesitis ranged between 41% in patients with axSpA and 65% in patients with Juv-SpA. Dactylitis was most frequent among patients with PsA (37%). CONCLUSION: These results suggest that all peripheral features can be found in all subtypes of SpA, and that differences are quantitative rather than qualitative. In a high proportion of patients, axial and peripheral manifestations coincided. These findings reconfirm SpA clinical subtypes are descendants of the same underlying disease, called SpA.

Prevalence and pattern of comorbidities in chronic rheumatic and musculoskeletal diseases: the COMORD study.

Increased risk of comorbidities has been reported in Rheumatic and Musculoskeletal Diseases (RMD). We aimed to evaluate the prevalence and pattern of comorbidities in RMD patients nationwide, to identify multimorbidity clusters and to evaluate the gap between recommendations and real screening. Cross-sectional, multicentric nationwide study. Prevalence of comorbidities was calculated according to six EULAR axes. Latent Class Analysis identified multimorbidity clusters. Comorbidities' screening was compared to international and local recommendations. In 769 patients (307 RA, 213 OA, 63 SLE, 103 axSpA, and 83 pSA), the most frequent comorbidities were cardiovascular risk factors and diseases (CVRFD) (hypertension 36.5%, hypercholesterolemia 30.7%, obesity 22.7%, smoking 22.1%, diabetes 10.4%, myocardial infarction 6.6%), osteoporosis (20.7%) and depression (18.1%). Three clusters of multimorbidity were identified: OA, RA and axSpA. The most optimal screening was found for CVRF (> = 93%) and osteoporosis (53%). For malignancies, mammograms were the most optimally prescribed (56%) followed by pap smears (32%) and colonoscopy (21%). Optimal influenza and pneumococcus vaccination were found in 22% and 17%, respectively. Comorbidities were prevalent in RMD and followed specific multimorbidity patterns. Optimal screening was adequate for CVRFD but suboptimal for malignant neoplasms, osteoporosis, and vaccination. The current study identified health priorities, serving as a framework for the implementation of future comorbidity management standardized programs, led by the rheumatologist and coordinated by specialized health care professionals.

Structural progression in axial spondyloarthritis.

Functional disability in axial spondyloarthritis is related to the structural progression caused by the disease, thus largely contributing to its global burden and still representing a major challenge in management. Diagnosis at an early inflammatory stage of the disease is the hallmark for a better disease control and management. The natural history of axial spondyloarthritis is now better understood with imaging studies and long-term follow-up data, with some predictive factors for structural progression being identified. Non-steroidal anti-inflammatory drugs are still considered as the first line treatment for axial spondyloarthritis, however, their impact on structural progression is conflicting. Recent data on biologic disease-modifying anti-rheumatic drugs, such as tumor necrosis factor inhibitors have shown significant retardation of radiographic damage after several years of treatment, while first data with interleukin-17 inhibitors were also positive. Novel emerging drugs are being evaluated with promising results on halting disease progression. This review summarizes the predictors of radiographic progression in patients with axial spondyloarthritis as well as the current evidence on the effect of available treatments on structural progression.

OBJECTIVES: Musculoskeletal ultrasound has evolved throughout the last decade. This procedure allows accurate corticosteroid injections guidance. Precision is much higher than the infiltration performed blindly or under fluoro- scopy. The purpose of our approach is to describe our tech- nique in ultrasound-guided infiltration of the shoulder with an overview of the results. MATERIAL AND METHOD: 123 cases of ultrasound-guided infiltration of the shoulder were selected in our institution from July 2011 to June 2012. They are divided into sub-acromial sub-deltoid bursitis, biceps tenosynovitis, acromioclavicular osteoarthritis, adhesive capsulitis and cal- cific tendinosis lavage and aspiration. RESULTS: The infiltra- tion technique and the sonographic appearance in each con- dition are described. The rate of improvement is estimated between 70 and 80%. CONCLUSION: The ultrasound-guided infiltration provides an accurate and minimally invasive thera- peutic option before any surgery. Recovery and socio-profes- sional integration prove to be optimal and fast.

Prevalence and predictors of vitamin D inadequacy amongst Lebanese osteoporotic women.

In Middle-Eastern countries, more particularly in Lebanon, the incidence of vitamin D deficiency has been found to be surprisingly high in schoolchildren and young individuals. However, the prevalence and risk factors for vitamin D inadequacy amongst Lebanese osteoporotic women seeking medical health care has never been studied. We analysed vitamin D-inadequacy risk factors among the 251 Lebanese postmenopausal osteoporotic women (from both Muslim and Christian communities) who participated in a vitamin D international epidemiological study. Vitamin D inadequacy prevalence (25-hydroxyvitamin D (25(OH)D) , 30 ng/ml) was 84.9%. 25(OH)D was negatively correlated with BMI (r 20.41; P<0.001) and positively correlated with educational level (r 0.37; P<0.001) and self-reported general health (r 0.17; P<0.01). No significant correlation was found with age and no seasonal variation was observed. There was no significant correlation between 25(OH)D and sun exposure index or vitamin D-rich food consumption. However, 25(OH)D strongly correlated with vitamin D supplement intake (r 0.48; P<0.0001). Muslim community participants had lower 25(OH)D levels compared with their Christian counterparts (P<0.001). They also had higher BMI, lower educational level and vitamin D supplement consumption and followed more frequently a dress code covering the arms (P<0.0001 for all variables). In a multivariate model, in Muslims, inadequate vitamin D supplements and a dress code covering the arms are the independent predictors of 25(OH)D inadequacy (P<0.001 for both variables). However, in Christians, the predictors are inadequate vitamin D supplements, high BMI and low educational level (P<0.001; P=002 and P=0.02 respectively). There is an urgent need to increase vitamin D supplement use in Middle-Eastern osteoporotic women, more particularly in those from the Muslim community.
