Abstract
The purpose of this study was to estimate the prevalence of diabetes in Oregon's adult Medicaid population and to compare the level of diabetes-related preventive care with the state's general population. Responses to telephone interviews conducted in 1999 among 2,770 randomly selected adult Medicaid beneficiaries and 7,229 Oregon residents were compared. Diabetes prevalence among adult Medicaid recipients (11.1% [95% Cl, 9.9% to 12.2%]) was more than twice that in the general population (4.7% [95% Cl, 4.2% to 5.3%]). During the year prior to the interview, adults with diabetes in the Medicaid and general populations reported performing the following preventive care, respectively: > or = 2 diabetes care visits (80%, 77%); foot examination (74%, 74%); dilated eye examination (73%, 68%); influenza vaccine (65%, 61%); self-monitored blood glucose daily (63%, 61%); pneumococcal vaccine (51%, 47%); regular aspirin use (48%, 53%); and awareness of Hemoglobin A1c (34%, 39%). Although the reported prevalence of diabetes in Oregon's Medicaid population is high, the prevalence of diabetes preventive care activities was similar to the state's general population. Nonetheless, specific services in both populations could be improved.
