Diabetes in Hawaii: Estimating prevalence from insurance claims data

Objectives. The purpose of this study was to determine the prevalence of diabetes mellitus in Hawaii from insurance claims data. Methods. Information from two major health plans covering approximately 66% of the state's population was used to estimate prevalence rates by sex, age group, and geographic area. Weighted multiple linear regression was applied to identify predictors of diabetes prevalence. Results. The statewide diabetes prevalence was estimated at 43.8 per 1000 persons. The ethnic composition of the population and rural residence partially explained the geographic variation in diabetes prevalence. Conclusions. Insurance claims data may be a useful tool for population-based diabetes surveillance.
