Low prevalences of chronic widespread pain & shoulder disorders among the Pima Indians

OBJECTIVE. To establish the prevalence of shoulder disease and

chronic widespread pain in Pima Indians.


sectional analyses of data from 4230 subjects for shoulder

disease and 105 subjects for chronic widespread pain

participating in population surveys

RESULTS. The prevalence of

shoulder disease was 4.4% (95% CI, 3.8-5.1), age-sex adjusted

to the 1980 US census population. This is lower than in a

study of Caucasians [prevalence ratio (PR) = 0.29, 95% CI,

0.20-0.42 for men and PR = 0.55, 95% CI, 0.41-0.73 for women].

Shoulder disease was associated with non-insulin-dependent

diabetes mellitus (PR = 1.67, 95% CI, 1.19-2.36). No chronic

widespread pain was identified (95% CI, 0-3.5%).


Prevalence of these pain syndromes in Pima Indians is lower

than in predominantly Caucasian populations. These findings

suggest that these populations have different pain perception

or different patterns of risk factors for these disorders.
