ObjectiveTo estimate urban prevalence of rheumatic musculoskeletal (MSK) disorders and compare to an earlier rural regional study.MethodsWe screened 8145 adults from a preselected urban locality in Pune, India, for MSK pain in a cross-sectional house-to-house survey (Stage I) over 20 weeks. The World Health Organization-International League of Associations for Rheumatology (WHO-ILAR) Community Oriented Program for Control of Rheumatic Diseases (COPCORD) Bhigwan model was used. Thirty trained community volunteers completed Phases I and II questionnaires, concurrent with rheumatology evaluation (Phase III). Clinical diagnosis was based on standard diagnosis/classification criteria. Point prevalence rates from our survey and the earlier Bhigwan village (Pune district) survey were standardized (adjusted age-sex to India population census 2001) and are reported for osteoarthritis (OA), rheumatoid arthritis (RA), seronegative spondyloarthritis (SSA), and inflammatory arthritis (IA).ResultsOne thousand one hundred fifty-two urban cases (65% women) were identified (14.1%, 95% confidence interval 13.4, 14.9). The self-reported pain sites (Phase II) were hip (0.4), knees (6.3), ankle (1.9), feet (0.7), shoulders (2), hands (1.3), wrist (1.2), neck (1.9), upper back (1.7), low back (5.5), thigh (1.5), calf (1.4), and sole (0.8); corresponding rural sites being hip (1.1), knees (13.7), ankle (7), feet (1.6), shoulders (7.9), hands (6.3), wrist (6.9), neck (6.8), upper back (8.4), low back (12.6), thigh (4.8), calf (7.1) and sole (2.2). OA disorders, soft tissue rheumatism (STR) and ill-defined aches and pains were predominant in both surveys; < 10% reported IA. The major disorders among urban cases were OA (4), STR (1.2), RA (0.2, ACR criteria 1988), undifferentiated IA (0.3), SSA (0.3), and gout (0.06); corresponding rates in Bhigwan were OA (6.3), STR (3.8), RA (0.5), undifferentiated IA (0.8), SSA (0.3), and gout (0.1). Infections were conspicuously absent.ConclusionWhile similar in spectrum, standardized prevalence rates of self-reported pain sites and rheumatic MSK disorders were significantly lower in the urban (current Pune COPCORD surveys) versus rural (Bhigwan) community, and in both communities aches and pains that are poorly understood by modern science were predominant.
