Slow walking at 45 'a sign of faster ageing'

I wondered what people on here made of this latest bit of research reported today on the BBC.

I can't see that anyone else has posted this, but I may be wrong? Apologies if this is posted on another thread somewhere.
Here is another link as I now see it is widely reported in the press.

Here is the actual study https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2752818

At 45 my walking speed was pretty fast. Of course it's not so great now I have a problem with my stamina - call it ME/CFS or what you will, though I am not severe, and if anything have improved somewhat. I have underactive thyroid so of course that is one aspect that affects stamina, quite apart from if there is another labelled differently. I am also 67 but my husband at 73 is a lot faster than I am and can walk distances and up hills with ease.

What does this mean for those with ME/CFS then? Do we have a sign of faster ageing, and does it confirm that our brains are ageing too? I have seen many discussions over the years as to whether we have dementia or what, if our brains don't work properly with this condition. At this stage they seem to be possibly linking it back to childhood development of the brain though, so maybe not relevant if the walking speed has changed due to illness in midlife. How would they know what was what though?

Well since you ask I saw it and thought it looked like another load of nonsense from KCL.

"This study found that a slow walk is a problem sign decades before old age," said Prof Terrie E Moffitt, lead author from King's College London and Duke University in the US.

I pity anyone who has a perfectly good reason to walk slowly not related to any of the things they were looking at in the study.

The researchers said measuring walking speed at a younger age could be a way of testing treatments to slow human ageing.

A number of treatments, from low-calorie diets to taking the drug metformin, are currently being investigated.

It would also be an early indicator of brain and body health so people can make changes to their lifestyle while still young and healthy, the researchers said.

Looks like a prelude to more patient-blaming.

And the researchers found they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were three.

The children who grew up to be the slowest walkers (with a mean gait of 1.2m/s) had, on average, an IQ 12 points lower than those who were the fastest walkers (1.75m/s) 40 years later.

That just looks so fishy to me, but I can't be bothered looking into it in more detail, as reports like this are two-a-penny on the BBC website and I've only got so much time and energy. Sorry if that's a cop-out, but this article is near the bottom of my "things to be angry about" list so it just won't get done.
 
On the bright side @TiredSam it doesn't ACTUALLY mention people with ME or Chronic Fatigue Syndrome!

I think the problem is that even if they have discovered something regarding a link with neurocognitive function in childhood, that must surely be just a group of people with this issue, not everyone. After all, you may be taking medication that affects the brain that slows things up.

My son for instance was on long term medication for Tourette Syndrome and schizophrenia for 10 years, and should have been reviewed long before the 7 year point when I suggested to the psych that it was about time she looked at it. Since then he has been weaned off most of it. I have noted that he is mentally a lot brighter now as a result. Anyway just one example where this may not fit.

I noticed that it was KCL but the study was done in New Zealand.

By all means ignore the BBC connection as it is reported also in papers like the Independent and The Mail and often in those reports it gets sensationalised, but it's worth looking at the study maybe itself which I have linked to. It doesn't appear to relate to psychology in any way, but is more to do with neurological science.

I saw this study on my Twitter feed the other day. I've been a fast walker my entire life, even with ME, so I tirer much quicker. If I walk slow I lose my balance.

Same here - even today (I'm classed mild most of the time) I walk faster than most other people. It's just that if I do more than about half a mile I then suffer for days afterwards.

I'd assume that one of the factors that influences "gait speed" is BMI/obesity, and to the degree that being overweight influences longevity, that might be the more relevant factor.

There's debate whether the biggest problem with being overweight is yo-yo weight from going on weight loss campaigns repeatedly to try to achieve a weight that the bodies of many people who are overweight cannot sustain long-term.

Kaiser Health News likes the correlation between weight and disease, but I don't find value in that because I see people who do everything right and can't loose the weight.

Obesity stigma and yo-yo dieting, not BMI, are behind chronic health conditions, dietitian claims (Kaiser Health News)

Yo-yo dieting is dangerous even if you're not overweight (American Heart Association)

Someone wrote to me (in passing) about this study and I wrote more in reply than I intended.

So, getting more out of my spoons, I’m sharing my reply here too. [ETA: adding some extra spacing for ease of reading]

The walking speed study is about using walking speed as a metric for assessing health/illness at a younger age than previously.

It has been used for a while as a quick gauge for health/illness in aging people, and now it turns out to be a fairly good indicator of health status in younger people (from what I can see 45 is the first age in the large cohort study when a walking test is done so that’s why the test mentions 45yrs).
It indicates a range of things like heart disease, injuries, fitness and major illnesses. And can pick up on a range of things which might be hard to find in a blood test (eg brain difficulties) or just looking at someone (because walking quickly uses a lot of different things from balance to vision to coordination etc).
It’s not really a new idea, just a suggestion that we can use it to indicate when people of all ages need extra help. (I too use it with you: on days when I see you walking slower it tends to mean you’re not feeling well and it might be worth finding out why.)

I’m just mentioning it because your comments seem to forget that correlation is not causation. But the study is very much intended to be about correlation.

Tests that don’t require expensive equipment, blood draws or even access to medical facilities are valuable in countries like New Zealand which have publicly funded health care and may also be very valuable to places where access can be difficult.
That’s the value of the study. Not to say it’s better to be a fast walker but to say that if you have trouble reaching a good maximum speed then you may need some help. That you may need assessment to see if what is slowing you down is remediable.
Because early detection is more efficient for everyone involved.
 
I’m not saying that that’s what the media will take from it. Nor what those running the study might morph it into but it is what the study says it was trying to do.
I sincerely hope they stick to that.

I feel a lot less comfortable with the predictions from younger ages. I’d need to know a lot more about what they controlled for.
