Prevalence of musculoskeletal disorders and rheumatic diseases in an Argentinean indigenous Wichi community.

OBJECTIVE: To estimate the prevalence of musculoskeletal disorders (MSK) and rheumatic diseases in an indigenous Wichi population in Argentina. METHODS: This is a cross-sectional, community-based study using the Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) methodology in ≥ 18-year-old subjects. Validated surveys were conducted by trained interviewers. Subjects with MSK pain (positive cases) were evaluated by internists and rheumatologists for diagnosis and treatment. RESULTS: A total of 648 interviews were performed (90.4% of the census population). Mean age was 37.5 years (SD 14.8), and 379 (58.5%) were female. The mean years of education was 7.0 (SD 3.7); 552 subjects (85.2%) were covered by the public health care system. A total of 216 (33.3%) subjects had MSK pain in the last 7 days. Rheumatic disease prevalence was as follows: mechanical back pain (19.0%), rheumatic regional pain syndrome (5.2%), osteoarthritis (3.2%), rheumatoid arthritis (RA) (3.2%), inflammatory back pain (1.2%), undifferentiated arthritis (0.3%), Sjögren syndrome (0.15%), and fibromyalgia (0.15%). RA patients included 19 (90.5%) women and 9 (42.9%) with RA family history. One hundred percent were seropositive and 66.7% showed radiologic erosions. The mean of Disease Activity Score [DAS-28 (ESR)] at the time of diagnosis was 5.1 (SD 1.5) and the Health Assessment Questionnaire Disability Index (HAQ-DI) was 0.8 (SD 0.4). CONCLUSION: RA prevalence was 3.2%, one of the highest reported using the COPCORD methodology in indigenous and non-indigenous peoples in Latin America, with a high percentage of family cases. Pain and functional capacity were the variables allowing patients' early referral to a specialist. Key Points • The RA prevalence was 3.2%, one of the highest reported using COPCORD methodology in indigenous and non-indigenous peoples in Latin America. • The patients with RA had high percentage of familiar history of RA. • The pain and functional capacity were the variables associated with a diagnosis of any rheumatic disease and should be considered for early referral. • The mean of the delay in the diagnosis was 5.8 years. In this community, the lack of the "migration health" phenomenon may be a social determinant that negatively impacts their health.

Experiencia sobre el proceso de salud-enfermedad-atención en pacientes con artritis reumatoidea pertenecientes a la comunidad Wichí de Misión Chaqueña "El Algarrobal", Salta / Experience on the health-disease-care process in patients with rheumatoid arthritis belonging to the Wichí community of Mission Chaqueña "El Algarrobal", Salta

Introducción: se ha reportado que la prevalencia de artritis reumatoidea (AR) en la comunidad Wichí representa la más alta informada por el Grupo Latinoamericano para el Estudio de las Enfermedades Reumáticas en los Pueblos Originarios (GLADERPO). El objetivo de este estudio fue describir la experiencia sobre el proceso de salud-enfermedad-atención de pacientes con AR de la comunidad Wichí de Misión Chaqueña "El Algarrobal", Salta. Materiales y métodos: estudio narrativo. Diseño de corte etnográfico. Se realizaron entrevistas semi-estructuradas y observaciones registradas. Se utilizaron guías de entrevistas y observación. Los aspectos incluidos fueron: concepción del proceso salud-enfermedad, percepción de la AR en la vida diaria, el acceso al sistema de salud, utilización de recursos tradicionales y de medicina tradicional. Resultados: se realizaron 10 entrevistas. Los aspectos más relevantes fueron la concepción del proceso salud-enfermedad asociado al trauma social pasado y al concepto de voluntad Wichí. Se evidenció la combinación de estrategias para mejorar el dolor (biomedicina, medicina tradicional y acompañamiento religioso). Además, se observó una relación unidireccional con el sistema de salud. Conclusiones: la AR es una enfermedad con un impacto negativo en la comunidad Wichí. Se requieren otras actividades, desde otras disciplinas, para mejorar el acceso al sistema de salud y la continuidad de los tratamientos.

Introduction: the prevalence of rheumatoid arthritis (RA) in the Wichí community has already been published, representing the highest reported by the Grupo Latinoamericano para el Estudio de las Enfermedades Reumáticas en los Pueblos Originarios (GLADERPO). The objective was to describe the experience of the health-disease-care process of patients with RA from the Wichí community of Misión Chaqueña "El Algarrobal", Salta. Materials and methods: study with ethnographic design. Semi-structured interviews and recorded observations were conducted. Interview and observation guides were used. The aspects included were: conception of the health-disease process; perception of RA in daily life, access to the health system, use of traditional resources and traditional medicine. Results: ten interviews were conducted. The most relevant aspects were the conception of the health-disease process, associated with past social trauma and the concept of "Wichí good will". The combination of strategies to improve pain (biomedicine, traditional medicine and religious accompaniment) was evidenced. In addition, a unidirectional relationship with the health system was observed. Conclusions: RA is a disease with a negative impact on the Wichí community. Other activities from other disciplines are necessary to improve access to the health system and continuity of treatment.
