The great British booze rip off

From the Morning Advertiser:

UK consumers currently pay about 40% of the entire level of alcohol duty across the whole European Union.

This is a striking claim. I had heard that the British pay 40 per cent of all the beer tax in the EU, but I didn't realise that the same was true of all other alcoholic drinks.

Nevertheless, a check of the numbers in this EU document shows that it is true. The figures break down like this:

Spirits

EU total: €14.5 billion
UK total: €3.7 billion
UK percentage: 25%

Wine

EU total: €6 billion
UK total: €4 billion
UK percentage: 67%

Beer

EU total: €10
UK total: €4 billion
UK percentage: 40%

Sparkling wine

EU total: €1 billion
UK total: €460 million
UK percentage: 43%

Intermediate ('alcopops')

EU total: €700 million
UK total: €406 million
UK percentage: 58%

All alcohol

EU total: €31.2 billion
UK total: €12.5 billion
UK percentage: 40%


This is a rip off of British drinkers on an epic scale. The UK—which drinks less than the EU average—has 12 per cent of the EU population but pays 40 per cent of alcohol taxes. Pound for pound, we are paying more than three times as much alcohol duty than the EU average.

The exploitation of wine drinkers is particularly ruthless (most EU countries don't levy alcohol duty on wine at all), but every type of drink is subject to exceptionally high rates of tax. No wonder the European Commission thinks the British government can afford to give it another £1.7 billion.

Couch potatoes

From the Telegraph:

Couch potato lifestyles could kill the welfare state, landmark report warns

Couch potato lifestyles have left the UK with one of the lowest levels of activity in the western world, and without change, the welfare state could collapse, health officials have warned.

If the welfare state is so fragile that it can be brought down by people sitting about, perhaps we need a better system?

The welfare state won't be brought down under the weight of couch potatoes, however. This is just the latest scare story about obesity/smoking/drinking etc. bringing the NHS to "the brink of collapse". As I'm sure you know by now, obese people have lower heathcare costs than non-obese people.

At least Public Health England—for it is they—are talking about physical inactivity.

Officials warned that the UK population is now 20 per cent less active than it was in the 1960s...
The report by Public Health England says the typical lifestyle in Britain, with long hours spent in desk jobs, high levels of car travel and evenings spent watching TV or playing computer games is endangering the health of most of its population.
It warns: “Social, cultural and economic trends have removed physical activity from daily life. Fewer of us have manual jobs. Technology dominates at home and work, the two places where we spend most of our time. It encourages us to sit for long periods – watching TV, at the computer, playing games or using mobile phones and tablets. Over-reliance on cars and other motorised transport is also a factor.”

Indeed. I have been saying this recently on this blog and in an IEA report. If Public Health England conceded that calorie consumption has also been falling, we might get closer to understanding the real cause of the obesity 'epidemic'.

Michael Blastland gave a superb talk at the Battle of Ideas on Sunday in which he questioned why 'public health' folk tend to focus on diet, but not on exercise. He concluded that it is because there is no industry to attack and no legislation to campaign for. This, I think, is absolutely true. The public health lobby are one club golfers. If they can't blame industry for all the troubles of the world, they don't know what to do.

On a slightly related note, I am reminded of an anecdote in the great Petr Skrabanek's The Death of Humane Medicine which illustrates the yearning of epidemiologists to explain every premature death by reference to lifestyle.

When death strikes 'before its time', the victim's lifestyle becomes the subject of scrutiny. Death does not just happen. Something or somebody must be blamed. Obituarists casually search for snippets from the dead person's way of life which would 'explain' the timing and the mode of death.
When a 33-year-old friend of an epidemiologist suddenly died of a heart attack, without having any 'risk factors', the epidemiologist was greatly puzzled and so were his medical colleagues. 'The heart attack should not have occurred in this patient', was the verdict of experts. But it did. It was not fair. Was he a secret smoker? Had he used too much salt at home, even though he appeared to be shunning it in the hospital canteen? Then, finally, one doctor solved the mystery - the young man was a 'couch potato'.

Good cop/bad cop - how the BBC frames the debate on sugar

The BBC wants to know when if you've stopped beating your wife.


Last night the BBC broadcast Trust Me, I'm a Doctor. It featured a segment about sugar that was a nice example of how the media can narrow the terms of a debate while pretending to be neutral.

It started by showing some of the hysterical claims about sugar being 'the new tobacco' before declaring that it would be presenting the views of two scientists who held wildly differing opinions about the subject.

"To find out more, I've invited a couple of leading experts whose research has led to contradictory headlines..."

One of these experts was Simon Capewell of the anti-sugar pressure group Action on Sugar.

The other was Mike Rayner from the, er, anti-sugar pressure group Action on Sugar.

Only Capewell (bad cop) was introduced as being from Action on Sugar and it is simply not true that their research "has led to contradictory headlines". Both of them think that sugar is the leading cause of obesity, both of them think that the government should intervene in people's diets and both of them want sugar taxes. Rayner's research focuses on what a jolly good thing it would be if we taxed sugar and fizzy drinks. Capewell entirely agrees.

The main differences between the two is that Rayner (good cop) believes he is doing the Lord's work and he would like to broaden food taxation to go beyond sugar to deal with the whole diet:

"I don't care whether it's hot or cold, whether you got it from a takeaway or a shop - I'd like us to tax all unhealthy foods from butter to biscuits."

You can watch extended interviews of Capewell and Rayner by clicking on the links. Rayner certainly comes across as the saner and more thoughtful of the pair—and so he is—but this is because he rejects the garbage about sugar being addictive and/or toxic (which Capewell virtually admits he has to spout in order to get the attention of politicians).

Only in the fruity world of 'public health' can this be considered a meaningful difference. From Rayner's perspective, it is more reasonable to tax calories as calories rather than demonise sugar per se, but that is still a patently extreme point of view. And yet this guy is being wheeled out as the voice of reason!

I won't fisk Capewell's interview, although I am tempted. I hope that anyone who watches it will spot his duplicity and evasiveness when answering questions, as well as the eagerness of the presenter to help him out (to a laughable degree when the topic turns to addiction). Rayner got a slightly rougher ride, but there was no acknowledgement of the role of physical inactivity in causing obesity, nor was there any recognition of the fact that per capita sugar consumption is the same today as it was a hundred years ago. Both sides agree that sugar is the villain and the government needs to act, preferably with taxes.

By only showing us the devil and the deep blue sea, the BBC managed to make Rayner look like the good cop and Capewell the bad cop, but it was like a debate between a Marxist-Leninist and a Maoist, or a Hayekian against a Friedmanite. The shades of disagreement might seem significant to those who have already picked a side, but they are meaningless for those who want to see the bigger picture.

The effect—and, I assume, the intention—was to shift the debate from 'what's going on?' to 'what shall the government do?'

Heart miracles: Is the truth emerging?

If there is one pseudo-scientific claim that illustrates the credulity of the media and the duplicity of the public health movement better than any other, it is the idea that smoking bans lead to dramatic reductions in heart attack incidence.

It is now ten years since the British Medical Journal published Stanton Glantz's notorious 'Helena Miracle' study which claimed that the heart attack rate fell by 40 per cent after a small town in Montana banned smoking in pubs and restaurants. Numerous copycat studies followed, typically involving thinly populated towns and regions which, because of the small number of heart attacks that take place each month, are given to large fluctuations in hospital admissions.

From the outset, the most plausible explanation for the heart miracle phenomenon was that activist-researchers were scouring hospital records for unusual declines in heart attack admissions that roughly coincided with 'smokefree' laws. With so many smoking bans being enacted, it was inevitable that they would coincide with a blip in admissions now and again.

But when whole nations bring in smoking bans, the rate of decline has typically been zero or in the low single digits, ie. in line with the long term trend. (The most notable exception was a study of Scotland which claimed a 17% decline—a finding that is totally inconsistent with official NHS data.)

Having written about this for the five years, I was pleased to see some sanity rear its head in the American Journal of Medicine in January. A study by Basel et al.—which I have only just become aware of it thanks to Klaus in Denmark—looks at rates of acute myocardial infarction (heart attacks) in Colorado after a statewide smoking ban went into effect in 2006. This is of particular interest since two widely touted heart miracle studies have involved small pockets of Colorado. A 2006 study of Pueblo, Colorado claimed that there was a 27% decline in heart attacks when it went 'smokefree' in 2003 and a 2006 study of Greeley, a small town in Colorado, also claimed a 27% decline.

The researchers looked at the data for the whole of Colorado before and after its strict statewide smoking ban came into force. They looked first at total admissions for acute myocardial infarction and then they excluded the eleven towns and counties that already had smoking bans in place. In both instances, they found no effect from the ban.

We did not observe a significant decrease in acute myocardial infarction hospitalization rates in Colorado after enactment of a comprehensive statewide smoking ordinance. Even after removal of geographic regions where preexisting smoking ordinances were under enforcement, no statistically significant reduction in acute myocardial infarction hospitalizations was detectable. This contrasts with a number of prior studies, including local smoking ordinance studies in Pueblo and Greeley, Colorado, and adds to a growing literature that the cardioprotective effect of smoking bans may be less than initially suggested.


This finding is important and telling, but the study is also worth reading for its discussion of the existing literature. It is clear that heart miracles are confined to small, obscure towns in a way that can only be described as suspicious. (I have inserted hyperlinks to each study mentioned below.)

Overall, a review of published research shows that acute myocardial infarction RR reduction appears inversely related to sample size. For example, small studies in Bowling Green, Ohio, and Helena, Montana, found dramatic RR reductions (39% and 40%, respectively) but also had few acute myocardial infarction counts (58 acute myocardial infarctions in Bowling Green, 64 acute myocardial infarctions in Helena) and relatively small study populations (30,052 and 68,140, respectively). Studies in Greeley and Pueblo, Colorado, and Graubünden, Switzerland, found less dramatic RR reductions (27%, 27%, and 22%, respectively), corresponding to somewhat larger study populations (∼86,000, 147,751, and 188,000, respectively).


As the authors note, these large declines in small communities (which are not just implausible, but mathematically impossible), contrast sharply with evidence from large communities and whole nations.

...one national study used Medicare Provider Analysis and Review files and national death records; a nonsignificant reduction in acute myocardial infarction-related (RR, −4.1; 95% CI, −9.4 to 1.3) and all-cause (RR, −0.7, 95% CI, −2 to 0.6) mortality was observed 1 year after smoking ordinance enactment. In this study, researchers evaluated all possible pairs of ordinance and nonordinance hospitals and recorded the change in acute myocardial infarction incidence post-ordinance. They found that RR reductions of 10% or greater were common, but that RR increases of 10% or greater were equally as common; taken in aggregate, the mean was near zero.

Another study examined 74 cities geographically distributed across the United States that were affected by smoke-free legislation. Individual cities showed wide variation in acute myocardial infarction incidence after ordinance enactment, with risk ratios ranging from −36% to +54%; however, the mean risk ratio for the 74 cities was 0.97 (95% CI, 0.96-1.02).

... A study performed in Christchurch, New Zealand after a countrywide smoke-free ordinance, found a 0% RR reduction in acute myocardial infarction with an approximate population size of 350,000. Countrywide studies with larger population bases provide concordant findings. In England, a 2.4% RR reduction was observed (population of 50 million). In Italy, a 4% RR reduction was observed (population of 58 million). In France, a 0% RR reduction was observed (population of 63 million). Finally, in a study examining the US Medicare population in states with a smoke-free ordinance versus those without, a 0% RR reduction was demonstrated (population of 30 million).

In the case of the English study, the heart attack rate fell at exactly the same rate after the smoking ban as it had been doing before the smoking ban. After dressing this up with some superficial computer modelling, Anna Gilmore—for it was her—relied on nothing more than a post hoc ergo propter hoc assumption. A similar claim, though never published, was made about Wales.

The authors attribute much of the heart miracle phenomenon to publication bias. That is likely to be a part of it, although I think that researcher bias and selection bias played more of a part.

These analyses support the hypothesis that small study populations may be more likely to find dramatic changes in acute myocardial infarction incidence, whereas increasing the study sample size attenuates the magnitude of the reduction. Also, review of the studies in aggregate reveals data asymmetry that suggests the potential for publication bias or heterogeneity not entirely explained by a random-effects meta-analysis. The presence of publication bias may explain why small sample size studies have tended to report large decreases in acute myocardial infarction incidence, whereas relatively few small sample studies have shown no effect.


The whole heart miracle scam has, in my view, been built on two simple tricks:

Firstly, dredging the data for any town that saw a large decline (in percentage terms) in heart attacks at around the time of a smoking ban. Nobody decided to do a study of Helena, Montana or Bowling Green, Ohio before the bans took place. The decision to focus on such obscure places came about only once it was clear that they were anomalous (not unlike Derren Brown's horse-racing trick). They were then presented to the media with the implication that they had been randomly selected.

Secondly, although less frequent, studies of larger populations have portrayed rather small declines in the heart attack rate as being the result of a smoking ban, without acknowledging that that there had been a secular decline of the same magnitude long before the ban was enacted. As the authors of the above study note, the secular decline is simply ignored in such cases.

That's really all there is to it. The 'public health' lobby has been selling this lemon to the public for ten years while describing sceptics, such as Michael Blastland (the creator of BBC's excellent More or Less series), as 'denialists' and 'dissidents'. The American Journal of Medicine study won't be enough to set the record straight in the public's mind—it received no media coverage, naturally—but it is further ammunition for those who do not believe in the 'noble lie'.


Henry Hill on public health

This, from Henry Hill at Conservative Home, is well worth reading...

The most important thing to bear in mind is that public health has no regard for individual choice. As a movement which measures its success largely in averaged outcomes and national statistics, its focus is not on minimising harm to third parties or helping individuals to make informed choices – although it will employ those arguments – but on controlling people to force its desired outcomes.

Boris’ quaint notion that there is no justification in preventing him lying on the grass with a cigar because he was harming nobody but himself will cut no ice with the public health movement. It’s bad for his health, so it should be stopped. Many, probably most, public health activists make no secret of their intention to prohibit tobacco.

But their ambitions are not limited to tobacco. Some months ago there was an outbreak of press hysterics about sugar, the ‘new nicotine’. This should have surprised nobody. There was always going to be a ‘new nicotine’, just as when sugar taxes have tripled the price of a Yorkie bar and we’re drinking cola from olive-green ‘plain cans’ with pictures of clogged arteries on them there would be a ‘new sugar’.

For years it has suited both sides of the public health debate to pick on cigarettes. Lovers of booze, food, or idleness could pretend that there was some particular wickedness in tobacco that warranted making a special case of it, whilst public health activists could establish useful precedents to wield against fresh targets when the time came.

Come that time has.

Were there really 9.6 million alcohol-related hospital admissions last year?

Mark Wadsworth has spotted that the number of alcohol-related hospital admissions have risen rather sharply in the last couple of years. In fact 'risen sharply' is an understatement. 'Rocketed into the stratosphere' might be a better way of putting it.

BBC, 26 May 2011: The number of alcohol-related hospital admissions in England has topped 1m for the first time, according to official statistics.

From The Daily Mirror, yesterday:

Heavy boozers are putting the NHS under “intolerable strain” and risk sparking a health crisis which will cost the country billions, a charity claimed yesterday. Alcohol Concern said 9.9 million NHS admissions in England – including hospital patients and clinic and A&E visits – were related to alcohol last year...


The Office for National Statistics is the usual port of call when looking up alcohol-related hospital data. Their latest figures for England tell us the following:

In 2012/13, there were an estimated 1,008,850 admissions related to alcohol consumption where an alcohol-related disease, injury or condition was the primary reason for hospital admission or a secondary diagnosis. Of the estimated 1,008,850 alcohol related admissions:

65% (651,010) were due to conditions which were categorised as partly attributable chronic conditions

6% (60,830) were for conditions categorised as partly attributable acute conditions

The figure of 1,008,850 admissions is considerably higher than it was a decade ago for various reasons, but it is lower than it was in 2011/12, 2010/11 and 2009/10.

Similar data from Scotland show that there were 35,926 alcohol-related discharges in 2012/13. Feel free to look up the figures for Wales and Northern Ireland, but it's quite obvious that the total number for the UK is nowhere near 9 or 10 million. It is an order of magnitude lower at just over one million. To put that in context, England's NHS deals with 125 million hospital admissions every year and alcohol-related admissions make up 1.4 per cent of the total.

There are various ways of inflating the number of alcohol-related admissions, such as widening the range of 'alcohol-related' illnesses and including admissions which are only partially related to alcohol. However, these techniques have all been exhausted and the ONS figures includes the widest range of admissions that can conceivably be described as alcohol-related.

The majority of admissions are not wholly, or even necessarily mainly, attributed to alcohol use. Most relate to chronic diseases such as hypertension and breast cancer. These figures are not calculated by doctors and nurses making assessments of patients. Instead, the system of alcohol-attributable fractions is used. This assumes that a certain percentage of admissions for each disease were caused by drinking. Chronic illnesses (which typically require many visits to hospital to treat) make up the majority:


Of the 1,008,850 admissions in 2012/13,

- around 711,840 admissions were for reasons that are partly attributable to alcohol consumption (i.e. the attributable fraction associated with the diagnosis (either primary or secondary) most strongly associated with alcohol consumption was less than 1)

- over half (57%) of these partly attributable admissions were for hypertensive diseases (ICD-10 codes I10 – I15), accounting for approximately 404,650 admissions. Admissions with other partly attributable diseases, injuries or conditions were much lower in comparison

- second highest condition in this category was cancer (ICD-10 codes C00 – C15, C18 – C22, C32 and C50 ) with 83,510 admissions (Table 4.1).

It is worth noting the various conditions that people are admitted for and the way they are categorised because the unwary newspaper reader might assume that all, or most, of the alcohol-related admissions are injuries, accidents and overdoses that take place on a Friday or Saturday night in 'Binge Britain'. That's hardly surprising when even the Morning Advertiser uses photos like this to illustrate the story.


But where does the 9.6 million (some papers reported 9.9 million) figure come from? The source is the temperance group Alcohol Concern who have been working their buddies in the pharmaceutical industry to produce a nifty website which supposedly allows users to see how many alcohol-related admissions there are each year in each area of the country.

They explain their methodology as follows:

The inpatient admissions and A&E attendances data in this map are for 2012/13. Estimates for outpatient attendances are based on benchmarks from the Birmingham Heavy Drinkers Project (1997 to 2004), The General Lifestyle Survey (2009) and the number of high risk drinkers taken from Local Alcohol Profiles (LAPE) (2005) estimates.

No more details are available but they have clearly derived estimates based on some (fairly old) data and some unexplained assumptions.

You would only bother coming up with estimates from a computer model if the real figures were not available. But here's the thing. The ONS has detailed hospital admission data for exactly the same areas that Alcohol Concern make guesstimates for. And what a difference there is between the ONS's figures and Alcohol Concern's estimates.

In Barnsley in 2012/13, for example, the ONS says there were 900 alcohol-related hospital admissions (600 were partly attributed to alcohol, 300 were wholly attributed to alcohol). Alcohol Concern says there were 46,992.

The difference between 900 and 46,992 is non-trivial to put it mildly.

To take another example from my neck of the woods, Alcohol Concern reckons there were 128,922 alcohol-related hospital admissions in West Sussex in 2012/13. The ONS says there were 14,210.

Alcohol Concern reckons there were 52,092 admissions in Brighton and Hove. The ONS says there were 4,640.

Alcohol Concern says there were 48,745 alcohol-related hospital admissions in Westminster. The ONS says there were 3,360.

These are massive discrepancies and Alcohol Concern make no attempt to explain why their figures are ten to fifty times higher than the ONS's. On the contrary, their press release implies that theirs are the official figures.

Since the ONS is a reputable organisation using official NHS records and a transparent methodology, I am inclined to think that their figures are much closer to the truth than those of a partisan pressure group.

Still, it got an enormous amount of newspaper coverage so well done Alcohol Concern. But be careful—one day a journalist might actually bother doing some basic fact-checking.

Leaked document shows WHO's hard line on e-cigarettes

I've received what appears to be the WHO's draft text about e-cigarette regulation (from this week's top secret FCTC meeting in Moscow).



Apologies for the poor quality of the image. You can click to enlarge, but this is what it says (all strikes and underlines are in the original. ENDs are 'Electronic Nicotine Delivery Systems', a daft term that only 'public health' people use for e-cigarettes):

(a) [preventing the initiation of ENDS by non-smokers and youth]

(b) minimize as far as possible potential health risks to ENDS users and protecting non-users from exposure to their emissions; non-users

(c) prohibit prevent unproven health claims from being made about ENDS the promotion of ENDS by any means that are false, misleading, deceptive or likely to create an erroneous impression about their characteristics, health effects, hazards or emissions; and

(d) protect existing tobacco control efforts activities from all commercial and other vested interests of the tobacco industry that produces and sells related to ENDS, including interests of the tobacco industry with measures similar to those considered in Article 5.3.

3. The Parties are invited to consider banning or regulating ENDS including as tobacco products, medicinal products or consumer products [or other categories as appropriate] taking into account a high level of protection for human health with special attention to vulnerable groups such as pregnant women.

Urges Parties to consider banning or restricting advertising, promotion and sponsorship of ENDs.

5. Invites Parties and WHO to comprehensively monitor the use of ENDS among smokers and non-smokers especially among youth including the relevant questions in all appropriate surveys on risk factors for non-communicable diseases...

The various deletions suggest that this may not be the finished article. Nevertheless, assuming that it is genuine and current, it is important to note that the WHO's position is to urge countries to ban the marketing of e-cigarettes. It would also like them to ban them entirely or regulate them as tobacco or medicinal products (which, of course, they are not).

Moreover, the WHO is also considering rolling out Article 5.3 to e-cigarette companies. Article 5.3 says that tobacco companies shouldn't be involved in setting public health policy. Anti-smoking cranks like to pretend that (a) it is a law (it isn't in most, if not all, countries), and (b) that it stops governments having any meetings with the tobacco industry or anyone who is vaguely connected to the tobacco industry. Some politicians have fallen for this lie. Extending Article 5.3 to e-cigarette companies would be a very bad idea as governments urgently need to hear from people who know what they're talking about with this emerging technology.

Finally, you will note the reference to 'protecting non-users from exposure' to e-cigarette vapour. This assumes that there is something in the vapour that non-users need to be protecting from, but there is no credible evidence for this. Clearly, the aim here is to encourage bans on e-cigarette use indoors (and, if pocket dictators like Lord Darzi have their way, outdoors too).

I stress again that the above may not be the final text, but if it bears any resemblance to the finished draft, it looks like the WHO will be recommending advertising bans, inappropriate regulation (up to and including prohibition), indoor bans on use and the exclusion of e-cigarette companies from the dialogue. Not quite the light touch we were led to believe would be the outcome of COP6.
