How Much Exercise Is Enough?

“I’m a minimalist when it comes to exercise. A really small, really intense dose is all that is needed for the vast majority of people to manifest all of the health benefits that exercise can provide. This does not mean that you can then get away with bed rest in the face of this concentrated dose of exercise, I’m not saying that at all. I’m saying that if a person is living a fairly “normal” life with a decent amount of non-exercise activity built into their day, not a lot of “exercise” is needed above that to maximize health markers.”

Why Do Obese People Have More Asthma?

It may be related to leptin, a hormone produced by fat cells (adipocytes).  ScienceDaily has all the details, most pertinent of which is that the study at hand was done in mice.  So not ready for prime time (humans).  Some of the sickest asthmatics I’ve cared for have been morbidly obese.

What Modifiable Factors Contribute to Premature Death in the U.S.?

In 2007, the New England Journal of Medicine published an article by Dr. Steven Schroeder, “We Can Do Better – Improving the Health of the American People.”  At the time, Dr. Schroeder was working in the Department of Medicine, University of California at San Francisco.  He opines that the “determinants of premature death” are a key measure of health status. Here’s a smattering of interesting quotes:

  • Health is influenced by factors in five domains – genetics, social circumstances, environmental exposures, behavioral patterns, and health care. When it comes to reducing early deaths, medical care has a relatively minor role.  [These five domains are his determinants of premature death.]
  • Even if the entire U.S. population had access to excellent medical care – which it does not – only a small fraction of these [early] deaths could be prevented.
  • The United States spends more on health care than any other nation in the world, yet it ranks poorly on nearly every measure of health status.
  • U.S. expenditures on health care in 2006 were an estimated $2.1 trillion, accounting for 16% of gross domestic product.  Few other countries even reach double digits in health care spending.
  • . . . inadequate health care accounts for only 10% of premature deaths . . .
  • The single greatest opportunity to improve health and reduce premature deaths lies in personal behavior [emphasis added].  In fact, behavioral causes account for nearly 40% of all deaths in the United States.
  • Although there has been disagreement over the actual number of deaths that can be attributed to obesity and physical inactivity combined, it is clear that this pair of factors and smoking are the top two behavioral causes of premature death.
  • If the public’s health is to improve, however, that improvement is more likely to come from behavioral change than from technological innovation.

My Comments

Behavioral patterns cause 40% of poor health and premature death.  Since healthcare determines only 10% of health status and premature death, let’s focus our health-promotion attention on the other 90% – behavioral patterns, social circumstances, genetics, and environmental exposure.  Bigger bang for the buck.

Don’t we the people already know what to do to improve our health?  Execution is the problem.

Most of the burden of poor health and premature death falls on the Medicare population, over 65 years old.  Much of this burden is a result of many years of poor health choices, such as obesity, physical inactivity, improper food choices, and smoking.  But who pays the bulk of healthcare costs of those choices?  Not the people who made poor choices, but the younger, working taxpayers.

The U.S. Medicare payroll tax is about 3% of gross compensation, and it’s paid by all working people, even healthy 20-year-olds who are barely making ends meet working at the “call center.”

People will make better lifestyle choices when they bear an immediate and/or direct cost for poor choices.  Let’s figure out how to do that, rather than having distant and unresponsive politicians and bureaucrats take over the healthcare and health insurance industries.

We’re smart enough to solve this problem.  But are we too lazy?

Gals, How Does Your Alcohol Consumption Compare?

“In 2011, more than 13.6 million U.S. adult women binge drank an average of three times a month, Brewer and colleagues reported. During each of those binge sessions, women consumed an average of six drinks, he said.

Bingeing is most common among women ages 18 to 34, and then gradually falls off with age. About 24% of women, ages 18 to 24, and 20% of those, ages 25 to 34, reported bingeing on alcohol.”
