How Medicaid affects adult health
Study: Health insurance helps lower-income Americans avoid depression, diabetes, major financial shocks.
“We find decreases in rates of depression, and we continue to find reduced financial hardship,” said MIT economist Amy Finkelstein. “However, we were unable to detect a decline in the incidence of diabetes, high blood pressure, or high cholesterol.”
Enrollment in Medicaid helps lower-income Americans overcome depression, get proper treatment for diabetes, and avoid catastrophic medical bills, but does not appear to reduce the prevalence of diabetes, high blood pressure and high cholesterol, according to a new study with a unique approach to analyzing one of America’s major health-insurance programs.
The study, a randomized evaluation comparing health outcomes among more than 12,000 people in Oregon, employs the same research approach as a clinical trial, but applies it in a way that provides a window into the health outcomes of poor Americans who have been given the opportunity to get health insurance.
“What we found was that Medicaid significantly increased the probability of being diagnosed with diabetes, and being on diabetes medication,” says Amy Finkelstein, the Ford Professor of Economics at MIT and, along with Katherine Baicker of Harvard University’s School of Public Health, the principal investigator for the study. “We find decreases in rates of depression, and we continue to find reduced financial hardship. However, we were unable to detect a decline in the incidence of diabetes, high blood pressure, or high cholesterol.”
