Will You Have Regrets on Your Death Bed?

A palliative care nurse asked dying patients what they would have done differently when they had the chance:

1. I wish I’d had the courage to live a life true to myself, not the life others expected of me.

2. I wish I hadn’t worked so hard.

3. I wish I’d had the courage to express my feelings.

4. I wish I had stayed in touch with my friends.

5. I wish that I had let myself be happier.

Read the rest. While you still have your health and time.

Do Vegetarians Live Longer?

They do if they’re Seventh Day Adventists living in Loma Linda, California, according to a report at MedPageToday.

As far as I know, I don’t know any Seventh Day Adventists. They may not be like the rest of us. For instance, about half of them consider themselves vegetarians. That percentage in the general U.S. population would be much lower. In the study at hand, the largest group of vegetarians (29%) were lacto-ovo vegetarians: they eat dairy  and eggs. Only 8% were vegans.

I wonder if Adventists tend to marry and breed with each other (like Mormons), thereby concentrating longevity genes?

The SDA’s of Loma Linda constitute on of the longevity hot spots identified in Dan Beuttner’s Blue Zones book.

Slower is better than faster.

Lots of other variables to consider, obviously.

Why Does the U.S. Rank Poorly In Longevity?

In the news once again is the poor ranking of the U.S. in terms of longevity compared to other developed countries.  As always, this will spark discussion about what can be done to improve our ranking.

The New England Journal of Medicine in 2007 published an article looking at the determinants of premature death (and poor health, by implication).  Here are some quotations from the article:

  • 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 the article author’s 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.
  • . . . 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.

Parker here again.

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.

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

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?

U.S. Life Expectancy: Overall Versus Type 1 Diabetes

Type 1 diabetics diagnosed in childhood and born between 1965 and 1980 have an average life expectancy of 68.8 years.  That compares to a lifespan average of 53.4 years for those born earlier, between 1950 and 1964.  The figures are based on Pittsburgh, PA, residents and published in a recent issue of Diabetes.

Elizabeth Hughes, one of the very first users of insulin injections, lived to be 73.  She started on insulin around 1922.

Average overall life expectancy in the U.S. is 78.2 years—roughly 76 for men and 81 for women.

Don’t be too discouraged if you have diabetes: you have roughly a 50:50 chance of beating the averages, and medical advances will continue to lengthen lifespan.

Huge U.S. Study Confirms Health and Longevity Benefits of the Mediterranean Diet

This is a reprint of the very first blog post I ever did, from December 24, 2007, at my old Advanced Mediterranean Diet Blog.  

We now have results of the first U.S. study on mortality and the Mediterranean dietary pattern.  380,000 people, aged 50-71, were surveyed on their dietary habits and scored on their conformity to the Mediterranean diet.  They were visited again 10 years later.  As you would expect, some of them died.  12,105 to be exact: 5985 from cancer, 3451 from cardiovascular disease, 2669 from other causes.  However, the people with the highest adherence to the Mediterranean diet had better survival overall, and specifically better odds of avoiding death from cardiovascular disease and cancer.  Compared to the people with low conformity to the Mediterranean diet, the high conformers were 15-20% less likely to die over the 10 years of the study.  The study authors, funded by the National Institutes of Health, noted eight similar studies in Europe and one in Australia with similar results.

Nothing to do with this post…I just like this picture

Once again, my promotion of the Mediterranean diet is vindicated by the scientific literature.  I’m not aware of any other diet that can prove anywhere near this degree of health benefit.  If you are, please share

Fat or Fit: Which Is Healthier?

Men live longer if they improve or maintain their fitness level over time, according to research out of the Cooper Clinic in Dallas, Texas. Part of that improved longevity stems from reduced risk of death from cardiovascular disease such as heart attack and stroke.

Compared with men who lose fitness with aging, those who maintained their fitness had a 30% lower risk of death; those who improved their fitness had a 40% lower risk of death. Fitness was judged by performance on a maximal treadmill exercise stress test.

Body mass index over time didn’t have any effect on all-cause mortality but was linked to higher risk of cardiovascular death. The researchers, however, figured that losses in fitness were the more likely explanation for higher cardiovascular deaths. In other words, as men age, it’s more important to maintain or improve fitness than to lose excess body fat or avoid overweight.

Mediterranean Diet Prolongs Life in Alzheimer Disease

A small scientific study of New York Alzheimer patients demonstrated significant increase in lifespan in those who had the highest adherence to the Mediterranean diet.  192 community-based individuals were followed for an average of 4.4 years (up to 13.6 years).  They were divided into three groups of Mediterranean diet adherence: low, medium, and high.  Compared to the people with low adherence, the others lived between 1 and 4 years longer.  Those with highest adherence lived the longest, suggesting a dose-response effect like we would see with many drugs.  No other diet has demonstrated this effect.

This same research group had previously reported that the Mediterranean diet lowered the risk for developing Alzheimer Disease in the first place.

Unfortunately, they did not report on whether the Mediterranean diet helped preserve brain function.  Prolongation of life by itself may be more of a curse than a blessing in advanced Alzheimer Disease.
