Abstract

Background Scientific information concerning the prevalence of musculoskeletal disorders in indigenous communities in Latin America is virtually absent. As a response to this knowledge gap, the Latin American Study Group of Rheumatic Diseases in Indigenous Peoples (GLADERPO) was created. This project lies within the framework of this regional effort.

Objectives Estimate the prevalence of musculoskeletal (MSK) disorders and rheumatic diseases in the indigenous Maya-Yucateco people using the COPCORD (Community Oriented Program for the Control of Rheumatic Diseases) methodology.

Methods Subjects ≥18 years of age from 13 indigenous Maya-Yucateco communities belonging to the Municipality of Chankom, Yucatán, Mexico. A cross-sectional, house-by-house, analytical community-based census study was performed. Bilingual staff members, who received standardized training, administered a cross-culturally validated version of the COPCORD questionnaire (1) to the adult population of the 13 communities. All cases of MSK pain were reviewed by primary care physicians, and if needed, by a physiatrist or a rheumatologist.

Results 1,522 of 2,442 community residents (63.2%) were surveyed. The mean age was 45.2 years (SD 17.9; range: 18 to 104); 933 (61.3%) were women. The mean years of education was 4.5 years (SD 3.6); 1,454 (95.5%) were employed with a monthly income below 195 US dollars; 1,403 (92.8%) were covered by the National Health Insurance Programme (“Seguro Popular”).

MSK pain during the last 7 days was present in 591 individuals (38.8%, 95% CI 36.3-41.3%). Of these, 210 (13.8%, 95% CI 12.1-15.6%) associated the pain to a traumatic event. Pain intensity was reported as “strong to severe” in 43.4%. Pain was located in the: knees (16.5%), spine (11.8%), shoulders (11.2%), and hands (10.5%).

Case figures and point-prevalence of main rheumatic diseases was: rheumatic regional pain syndromes (RRPS): 167 (10.9%; 95% CI: 9.5-12.6); osteoarthritis (OA): 145 (9.5%; 95% CI: 8.0-11.1); low back pain: 135 (8.8%; 95% CI: 7.4-10.4); fibromyalgia: 29 (1.9%; 95% CI: 1.2-2.7); rheumatoid arthritis (RA): 16 (1.0%; 95% CI: 0.6-1.7); juvenile idiopathic arthritis: 1 (0.06; 95% CI: 0.001-0.3); nonspecific arthritis: 6 (0.4%; 95% CI: 0.1-0.8); multiplex-case families RA: 2 (0.1; 95% CI: 0.01-0.4); and gout: 3 (0.2%; 95% CI: 0.04-0.5).

Conclusions The overall prevalence of MSK disorders in the Maya-Yucateco indigenous community of was 25.6%. RRPS and OA were the most prevalent rheumatic diseases. Remarkably, cases of JIA and multiplex-case families of RA were reported.
