The Role of Obesity in US Mortality

Recently there was a public debate between a physician and the Governor of New Jersey on the subject of weight. The Governor, pictured below, famously ate a donut on the David Letterman Show, eliciting this: “I’m worried he may have a heart attack. I’m worried he may have a stroke,” former White House physician Connie Mariano, M.D. said in an interview with CNN.

The media event continued with a press conference at which Governor Christie told the doctor to shut up, and a follow-up phone call in which he put the point more strongly. Nonetheless, he admitted that: “I have been remarkably healthy. My doctor continues to warn me my luck is going to run out relatively soon. So, believe me, it is something that I am very conscious of,”

There were suggestions that the doctor was diagnosing him long-distance, which is generally a breach of medical ethics if not common sense. I take that as political spin–the doctor was simply citing well-known demographic facts. For example, you only need to look at a recent study of the impact of obesity on longevity on 50-year-olds.

Researchers at the University of Pennsylvania applying statistical analysis to mortality figures were able to tease out the role of obesity.

In the United States, they concluded, obesity contributes to a loss of 1.5-2.0 years of life to men and women at age 50.

That conclusion is even more astounding when you consider that it is an average: many people lose considerably more than 2 years of life because they weigh too much: eating too much and exercising too little.

I confess that I do not like having a President who smokes. I also do not want a President who is morbidly obese. If Governor Christie represents everyman, then everyman needs to exercise more and eat less, beginning with less donuts.
