Health Insurance for All #insurance
The prospect of universal health coverage for all Americans is
weighing heavily on lawmakers right now. But, if the current proposals
pass Congress, Americans may be looking at an even “weightier” problem.
New economic research suggests that having health insurance actually
makes people fat, and that, in turn, increases health care spending.
A working paper recently published by the National Bureau of Economic
Research (NBER) discovered that Americans who have any type of health
insurance coverage, either public or private, are more likely to gain
weight and be obese. According to the
research, Americans with private insurance had increases in body mass
index (BMI) of 1.3 points, and those with public insurance had BMI
increases of 2.1 points. (Both of these findings were statistically
significant.)
The healthcare costs associated with obesity are overwhelming, and
account for nearly $150 billion annually in the United States, roughly
half of which is already funded by Medicare and Medicaid. This
translates to an additional $1400 per year in medical costs for an obese
person compared to a normal-weight individual. Remarkably, the cost of
treating obesity-related conditions and diseases has risen faster than
the incidence of obesity itself. The cost has nearly doubled in the last
decade, while the incidence of obesity has only increase by 37%. Today,
obesity-related costs account for 9.1% of total medical spending.
Economists have long shown that workers with employer-sponsored
health coverage, as well as all tax-paying Americans, pay the costs
associated with obesity through increased taxes, decreased wages, or
increased insurance premiums. Now, the authors of the NBER paper
actually call health insurance an “economic subsidy for obesity.” The
authors assert that people with health insurance are less
health-conscious and less attentive to weight gain since they believe
health insurance will cover the costs of their weight-related maladies.
The authors offer weak evidence that better insurance coverage begets
greater weight gain, and risk-adjusted health insurance deters weight
gain. Other economists have come to different conclusions using
different economics models and estimations, but most agree that obesity
needs to be addressed before medical costs can ever be contained.
Rather than making healthier lifestyles available to all Americans,
will universal health coverage create a moral hazard in matters of body
weight? The authors of the NBER paper think so. Instead, they contend
that providing incentives for healthy behaviors and lifestyle choices
will improve social welfare more than providing blanket coverage for
everyone. If the latter becomes reality, the United States may need a
mighty big blanket.
