Adults, obese and otherwise

PIck well and cut back your waste/waist

In my last post I explained the concept and the math behind the body mass index (BMI) approach to evaluating if your weight was normal or not (your BMI is very  well in synch with the most scientific methods of determining body fat percentages). Now I want to expand on that a bit  with some recent statistics and some thoughts on how we can lose weight if we need to. Unfortunately, some of us have lots of extra pounds we should shed if we want to have our best shot at leading long, healthy lives.

The Feb 1, 2012 issue of JAMA had a number of interesting articles on obesity. I've previously mentioned several on childhood and adolescent obesity; today I'd like to zero in on two whose focus is American adults.

Four CDC staffers, led by Katherine Flegal, PhD, published the most recent statistics from a recurring national survey with the daunting acronym NHANES. This national health and nutrition survey (the E stands for examination) started in 1971, but from 1999 on has been released results in two-year cycles. The current article from the National Center for Health Statistics, looking at the 2009-2010 NHANES data had a little good news and lots of bad news.

After 1980, until the turn of the 21st century, the prevalence (scientific term for percentage) of obesity in our population kept zooming up. Now it appears to have leveled off. I guess that's something we should be happy about, except now over 35% of adults in this country are obese. Men and women have about equally high rates of obesity and men have caught up to women in this regard over the last twelve years. Some subsets, by sex and racial groups, are even more likely to be obese or very obese.

The worst news from this article was that no group--men, women, non-Hispanic whites, Hispanics or non-Hispanic blacks--had a decrease in the prevalence of obesity in this most recent data set.

So which exercise and diet should we try?

getting enough exercise is difficult when your joints hurt

Many adults report "No Leisure-Time Physical activity." Overall, more of us are exercising, but the data vary from state to state. Those who have arthritis, fifty million in the US, need special attention or are even more likely to get no exercise. The CDC has worked with the Arthritis Foundation to develop ideas for this huge group. Going back to my review of articles on youngsters, I think for the rest of us, we could begin with simple steps, parking at the far end of the parking lot and substituting some walking for part of our screen time as two examples.

Harvard Medical School's free online HEALTHbeat publication had a review of pros and cons of various diets in its Feb 7, 2012 edition. The bottom line still is if you want to lose weight, you must cut down on your calories. The Mediterranean-style emphasis on fruits and vegetables, unrefined carbohydrates, nuts, seeds and fish may be the most effective in reducing cardiovascular and diabetic risks.

My New Year's Resolution is to keep my weight under 150 pounds. I have to work at it as I like to eat, but most of the time I've stayed away from splurges.

How about you?

Slim down those truckers

Wednesday, November 23rd, 2011

some truckers are relatively slender

I have two series of posts going, but couldn't resist the article I found in the New York Times while riding a recumbent bike in the gym. The title alone, "A Hard Turn: Better Health on the Highway," was enough to grab my attention.

The first story was typical, a trucker driving long hours every day, eating all the wrong foods, getting no exercise, gaining huge amounts of weight. I found the online abstract of a 2007 Journal of the American Dietetic Association article cited: long-haul truckers of necessity eat at truck stops and of 92 such truckers stopping at a Mid-eastern US truck stop nearly 86% were overweight and 56.5% were obese.

One of our family members used to be a truck driver and I've heard his stories of long days spent behind the wheel, eating greasy foods when he stopped. He's slimmer now and in better shape as his current employment allows him more exercise time and a choice of where and what to eat.

Now that insurance costs are rising sharply, the trucking firms are getting involved and the truckers themselves, there's over three million of them in the US, are coming to grips with the issue out of necessity. One group ran a blood-pressure screening clinic for 2,000 truckers at a truck show. Twenty-one were immediately sent to a nearby emergency room; one had a heart attack before reaching the hospital.

drive carefully around trucks like this

Trucks are involved in 400,000 accidents a year and 5,000 fatalities. I just watched a nearly eighteen minute video on how we, as drivers of passenger vehicles, contribute to those accidents; 70% are caused by the drivers of other vehicles (see link below). Yet many of the ones caused by trucker driver error occur because the trucker has a health problem or falls asleep.

Some truckers are taking steps to decrease their weight and its accompanying risks for themselves and those who share the roads with them. A number of companies are helping (and perhaps finding a lucrative new client group). I just looked at a website for "Rolling Strong," and found a gym in my area that offers fitness programs for truckers. Others are joining Weight Watchers, a solid organization that my slender wife has belonged to for many years (she says she was "chunky" in high school) or creating their own programs for fitness: one carries a fold-up bike in his 18-wheeler and uses it whenever he stops for a break. Many are cooking in their trucks or even hiring a trainer.

Others joined the Healthy Truckers Association of America, paying $7.50 a month to belong to an organization that is rapidly growing (see link below to Chicago tribune article). That group now offers truckers a prescription drug card enabling its members to save ~60% on meds.

I applaud all these moves; if I'm on the road with a large truck or a series of them, I'd like their drivers to be in shape and wide awake.

More on Pollan's book: "In Defense of Food"

Friday, December 11th, 2009

I wrote a brief blurb on three excellent books in the diet/lifestyle arena recently, cogitated a bit and decided I needed to spend some more time on each of the triad. Let's start with Pollan's books. I really enjoyed The Omnivore's Dilemma (2006). There he discusses (and he and his family try) four American food chains: food from standard supermarkets, from large-chain supposedly organic stores, from farmers markets and, finally from his attempts to be  a hunter-gatherer. After my wife read the book, we started haunting the farmers markets, bought a bison and a lamb and bought three EarthBoxes.

Our diet changed, although it wasn’t ever “bad.” We cook at home  a lot, use fresh produce whenever possible, eat lots of vegetables and fruits and consume red meat sparingly. After reading Pollan’s latest book, 2008 paperback, In Defense of Food: An Eater 's Manifesto (IDOF),we've gone a lot further. For instance, early in IDOF he comments we should avoid foods that make health claims, because those “food products” aren’t really food.

Pollan’s advice on food products is exceedingly sound: he recommends we avoid those that contain ingredients that are unfamiliar, unpronounceable, more than five in number or contain high-fructose corn syrup. I’ve actually been doing this much of the time for years; I now do it much more frequently.

We live in an age where nutritionists and a huge food industry shape the shopping choices of most Americans. Yet our health statistics don’t reflect the claims made in favor of this or that food product or supplement. It’s time to get back to basics, eat food that isn’t shipped 6,000 miles, ignore the latest diet fads and widen our food choices, including trying plants we’ve ignored previously.

Read IDOF; it’s well worth your time.
