A new study in the influential policy journal Health Affairs gives added credence to the idea that much of what drives health falls outside of the realm of medical care.

What better place to test this theory than in Canada – our northern neighbor with a publicly financed universal health care system. Researchers looked at nearly 15,000 Canadians in the nation’s health system who were free of heart disease and tracked them for at least a decade.  Not surprisingly, people disadvantaged by little education and low income, used the health care system more than those with higher incomes. But more importantly, this increased use of services had no discernable effect on improving their health or cutting their death rates – the ultimate bottom line – when compared with others with higher education, higher income and LESS usage of health care.

It may be helpful to have insurance to get care, but the United States cannot expect that giving people medical care will diminish differences in health outcomes or the likelihood of an early death among disadvantaged people. The authors explicitly warn against relying on universal coverage to eliminate inequalities in health.Continue reading…
