Coronavirus outbreak

[DCLane]

@kingrollo - SWMBO, who's a Registered Dietitan and Registered Nutritionist, uses both BMI and skin-fold thickness which gives a better body fat percentage.

Interesting. Maybe as aside but hasn't bmi been discredited as a health indicator ? - from memory it wasn't a good measure for people who had bulked up in the gym , they have a low fat % - but still score poor on BMI.

Theres also the deadly 'skinny fat' who are slightly built and sail though any BMI stats\measurements - but because of thin bones actually have a lot of fat !

The only 2 people I’ve known personally to have Covid bad are very over weight & one was in his 20’s.
To catch it mild you’re unlucky & to have a bad case you’re very unlucky & to die you’re super unlucky. Not even the top scientists can predict how things will be at Christmas time. It’s just the new normal so we must get on with life & stop virtue signalling on social media.

The only two people I know from my family who have died from Covid were thin, caught it in hospital while they were having an operation for something unrelated…..and sadly never came out. Yes, obesity is a risk factor (because of breathing problems) but thin people have died.

Age is a major risk factor too, and many older folks are not obese

Body builders don't make up the majority (or bulk) of those classified as obese

Of course not. They are just one group where BMI would give a misleading reading. Skinny but flabby being another.

The point of what I was saying is that these groups would poor BMI stats but be in good shape health-wise and vice versa for skinny fat.

Whichever, the relationship between high BMI and severity of illness seems to show that BMI is a useful rough and ready guide, even with the outlying groups included.

When I finally realised I needed to shed some weight, my BMI which was then about 82 kilos was a wake up call that much more had to go than the four or five I had envisaged! That would have left me significantly overweight despite fit through cycling.

Surely the only real outliers of BMI are heavily muscled types, certainly everyone I know (good friends) who are BMI 25+ (some 35-40) claim that BMI isn't a good guide to obesity are simply clutching at straws to defend themselves from being classed 'obese'. Most importantly every last one of them just over eats /drinks - I 'can put it away' but not in their league, obviously none of them now have the remotest possibility of working any of it it off after years of overeating.
Incidentally none of them pass the half height as a waist measurement test either.

I was once a BMI denier too, I still overfuel on occasions (so most weekends!) but I can get it back in the week using portion control, and lots of cycling/walking.
My BMI is now 23 from something north of 28 (when realisation dawned), goal is to be around BMI 21.5 so smack in the middle of the range (so lose another 12lbs) but should that loss make me look ill, or stop me riding distance for lack of 'stamina/reserves' then I'll review my weight, but I suspect it will just get rid of my belly. I made excuses for unhealthy lifestyle for years - erm decades!

the complexity is why I have avoided sharing so far.

But advice from senior medics seemed worth sharing

Dozens of Tory MPs defying speaker and refusing to use a mask

 

[lane]

Why is she having to isolate?
Wasn’t she wearing PPE? She didn’t have the NHS App switched on did she?

(sorry for the questions but she shouldn’t be having to isolate if IPC rules followed)

You may be correct and someone on a ride yesterday told me the same. She was wearing a mask. It is quite confusing and I haven't seen the communications she received - one via the app and one by email.

Unfortunately me telling Mrs Lane that I have received advice from a mate on a ride and someone on a cycling forum hasn't cut much ice😄

She seems determined to do the right thing - even if it's the wrong thing. As a result I had to cancel the dentist - which to be honest wasnt much of a disappointment.

 

[midlife]

If it came by email wouldn't that be from test and trace so legal requirement to isolate?

@Andy in Germany shared this on the pingdemic thread which merits sharing on here:

Edit: My subsequent comment on that thread was:
"Would be great if you could find a reference for those percentages, Andy - I think it's an excellent clear message, nevertheless.
Although I think the first pairing should be 100%, and use that as a reference for the rest.
Clearly if the bloke on the right is fully vaccinated the risk of infection drops by 80% (insert other figure as you wish).
This graphic works on the premise the bloke on the left is infected.
ETA: Given the subject of this thread I'd observe that the bloke on the right would be pinged regardless. Perhaps there should be an option on the app to indicate the owner of the phone is masked up (or not)."

 

[Ajax Bay]

I can't be sure - but I thought I read a stat today that 40% of admissions are vaccinated people.???
If true the whole effectiveness of the vaccine must be in doubt.

I seem to be hearing everyday that double jabbed people are going down with covid. Weren't we told it's effectiveness was around 90%.????

I can't believe you indulge in this sort of misinformation. You posts normally have validity.

The hospital where I work there are rumours of redeployment of non clinical staff on a scale that will dwarf that of the first 2 waves.

Rumours. Bound to be some planning going on, for worst case scenarios. Look at the SPI-M modelling and look at the bounds of uncertainty (I shared one of these up thread).

How many people with two jabs and the 2-3 weeks after the second (to build up further protection) actually end up on death's door in ICU? I don't have the numbers, but I do know that people drawing the conclusion that " jabs don't work" need to be quoted in the OED under "Stupidity".

Absolutely - I assume that @kingrollo was trying to get someone to make this point.

For example, your first dose gives you a likely 76% efficacy rising to 82% after the second dose and time for that to take effect. This means that you are a lot less likely to get Covid than if you had not been vaccinated, but you can still get it.

A first dose of any vaccine will not give you 76% effectiveness against infection: more like 32%. But the second dose (14 days after) lifts that to 80+% right enough.
I pointed out that there would be a significant proportion on fully vaccinated in hospital and, tragically some would go on to die, about 6 weeks ago. Maths, innit. (@rt has effectively addressed this)
