OBJECTIVE--To estimate the prevalence of diagnosed diabetes among American
Indians and Alaska Natives served by the IHS. RESEARCH DESIGN AND
METHODS--This was a cross-sectional study of the 1987 IHS national
outpatient data base. RESULTS--Prevalence rates of diagnosed diabetes
determined from the IHS outpatient data base were consistent with recent
studies of diabetes in different IHS areas. IHS-wide, age-adjusted
prevalence was 69/100,000, or 2.8 times the U.S. rate. There was
considerable variation in prevalence rates of diabetes throughout the
country, with rates ranging from 15.3/100,000 in Alaska to 119.2/100,000 in
southern Arizona. CONCLUSIONS--This study documented the high prevalence of
diabetes among American Indians and Alaska Natives and the wide variation
in rates between different tribal groups. This study also demonstrated the
feasibility of using an outpatient data base to estimate rates of disease
that have uniform methods of diagnosis and result in frequent clinic
visits.
