Diabetes Screening Among Immigrants: A Population-Based Urban Cohort Study

RESULTSdScreening rates were slightly higher in the immigrant versus the general population (76.0 and 74.4%, respectively; P , 0.001), with the highest rates in people born in South Asia, Mexico, Latin America, and the Caribbean. Immigrant seniors (age $65 years) were screened less than nonimmigrant seniors. Percent yield of new diabetes subjects among those screened was high for certain countries of birth (South Asia, 13.0%; Mexico and Latin America, 12.1%;Caribbean, 9.5%) and low among others (Europe, Central Asia, U.S., 5.1–5.2%). The number of physician visits was the single most important predictor of screening, and many high-risk ethnic groups required numerous visits before a test was administered. The proportion of diabetes that remained undiagnosed was estimated to be 9.7% in the general population and 9.0% in immigrants.
