The aim of this study was to identify differences in the prevalence and odds of cognitive impairment, hearing impairment, vision impairment, limitations in activities of daily living (ADLs), and ambulation limitations among three groups of older American adults: high school dropouts, General Educational Development (GED) recipients, and high school graduates. This study used secondary analysis of the nationally representative 2017 American Community Survey. The sample included 20,489 GED recipients, 154,892 high school graduates, and 49,912 high school dropouts. Our findings indicate that there is a gradient in health outcomes among older Americans, with the highest prevalence and odds of cognitive impairment, hearing impairment, vision impairment, ADL limitations, and ambulation limitations among high school dropouts, followed by GED recipients, and the lowest among high school graduates. Although GED recipients have better health outcomes than high school dropouts, there is still a significant disparity in health status between GED recipients and high school graduates.
