We estimate the effects of the ACA’s Medicaid expansion on health outcomes with a difference-in-differences approach, using restricted geotagged NHANES data from 2007 to 2014. Our results show that the partial Medicaid expansion in 2014 is significantly associated with a decrease of 8.465 mg / dL (4.3%) in total cholesterol and decrease of 5.569 mmHg in systolic blood pressure (4.7%). These are both likely the result of an increase in the use of cholesterol lowering medications, which can affect both of these measures and there is no corresponding increase in blood pressure prescription. Contrastingly, we find no statistically significant effects for diabetes prescriptions or measures.
