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.
