OP0167 Prevalence of Rheumatic Disease in Latin American Indigenous Population: A Community Based Study

Abstract

BackgroundGLADERPO group (Latin American Study Group on Rheumatic Diseases in Indigenous Peoples) is an organization aimed to conduct studies on indigenous populations with the purpose of closing the gap of information about rheumatic diseases and develop culturally-sensitive interventions.ObjectivesEstimate the prevalence of musculoskeletal disorders and rheumatic diseases in eight Latinoamerican indigenous communities using the COPCORD methodology.MethodsA cross-sectional, house-by-house, community-based census study was performed. Bilingual staff members, who received standardized training, administered a cross-culturally validated version of the COPCORD questionnaire to adult indigenous population with the assistance of bilingual translators. Individuals with musculoskeletal pain, stiffness or swelling in the last 7 days and/or at any point during their lifetime were evaluated by participating physicians (general physicians and rheumatologist) to classify or diagnosed any rheumatic disease according to specific criteria.ResultsWe surveyed 6,155 indigenous people having a mean age of 41.2 years (SD 17.6; range 18 to 105); 3,757 (61.0%) were women. Mean education was 5.0 years (SD 4.1); and 4,668 (75.8%) work for living.MSK pain in the past and during the last 7 days occurred in 2,778 (45.1%; 95% CI 43.8–46.3) and 2,127 individuals (34.5%, 95% CI 33.3–35.7%), respectively. Of these, 1,195 (56.2%, 95% CI 54.1–58.3%) individuals associated pain to trauma. Pain was severe in 15.8% and according to localization, pain originated from the spine (26.7%), the knees (17.6%), shoulders (15.3%), and hands (10.6%) more frequently.Point-prevalence of main rheumatic diseases was: low back pain (LBP) in 821 (13.3%; 95% CI: 12.4–14.2); osteoarthritis (OA) in 598 (9.7%; 95% CI: 8.9–10.4); rheumatic regional pain syndromes in 368 (5.9%; 95% CI: 5.3–6.6); rheumatoid arthritis (RA) in 85 (1.3%; 95% CI: 1.1–1.7); systemic lupus erythematosus in 7 (0.1; 95% CI: 0.004–0.2); nonspecific arthritis in 13 (0.2%; 95% CI: 0.1–0.3); spondyloarthritis in 12 (0.1; 95% CI: 0.1–0.3); and scleroderma in 3 (0.04%; 95% CI: 0.01–0.1).There were marked variations in the prevalence of each rheumatic disease among the different communities, i.e.: RA prevalence was 2.4% in Qom (Argentina) and 0.4% in Mixtecos (Mexico).ConclusionsThe overall prevalence of MSK disorders in indigenous community of Latin-American was 35.4%. Low back pain and OA were the most prevalent rheumatic conditions, but wide variations according to population groups occurred.AcknowledgementNational Council for Science and Technology (CONACYT)- Salud 2001–01–162154 (Mexico).

The Prevalence of Rheumatoid Arthritis in Chile: A Nationwide Study Performed as Part of the National Health Survey

“…Among RA cases in Chile, there was a high frequency of Mapuche ethnicity (22%), which represents more than the usual proportion of this ethnicity in the country (9.9%) 32 , suggesting RA may be more frequent in Mapuche people. A higher prevalence of RA has been found in other indigenous populations 33 . However, these findings are tentative because the total number of RA cases was low and this result could be a random finding.…”

“…Our study is suggestive of a higher risk of RA in subjects with high SES. Findings regarding the risk of developing RA in relation to SES have not been uniform in the past 33,34,35,36 . There are some characteristics in this population that may be related to our findings.…”

Validation of Modified COPCORD Questionnaire Indonesian Version as Screening Tool for Joint Pain and Musculoskeletal Diseases

“…The consideration of COPCORD as a standardized tool, requires validation of certain aspects like diagnostic tests, especially when compared to complete examination conducted by rheumatologist. 24,25 In the other hand, the adaptation and translation into Indonesian questionnaire also have consequences in language and cultural adaptation that may be different from the original. 26 Based on this fact, it is necessary to validate a modified COPCORD questionnaire Indonesian version for screening of joint pain and musculoskeletal diseases in Malang.…”
