Are nasty people more at risk from stroke and heart attack?

People who are antagonistic, competitive and aggressive may be at greater risk of having a heart attack or stroke. Researchers from the National Institute on Aging in Baltimore studied 5,614 Italians from Sardinia who ranged in age from 14 to 94. The participants answered a standard personality questionnaire that included six facets of agreeableness: trust, straightforwardness, altruism, compliance, modesty and tender-mindedness. The researchers then measured the thickness of their carotid (neck) arteries – the thicker people’s arteries the greater their risk of stroke or heart attack. Those who scored highest for antagonistic traits had greater thickening of their neck arteries and three years later they continued to be at more risk – especially if they were manipulative and quick to express anger. Those who scored in the bottom 10% of agreeableness and were the most antagonistic had a 40% greater risk of arterial thickening. In general men had more thickening of their arterial walls than women but if women were antagonistic they had the same risk as men. The researchers also measured the participants’ blood pressure, cholesterol and blood sugar and used statistical tools to take these variables ‘out of the equation’ in their analysis.

Troubled children stay troubled, poorer at greater risk

Behavioural problems in late childhood and early adolescence carry on into later adolescence and young adulthood and children from disadvantaged backgrounds are more at risk. Researchers from the University of Washington in Seattle studied 800 children and young adults between the ages of 10 and 24. Children from low-income backgrounds were twice as likely to report having had early sexual intercourse (by age 11) and early delinquency (by age 10) than those from middle-income backgrounds although children from middle-income backgrounds were 1.5 times more likely to say they started drinking early. Far from it being a phase that children grew out of those children who showed an early and frequent involvement with risky sex, delinquency and alcohol use showed an increase in long-term crime, drink problems and risky sex in young adulthood.

Can a Statin Neutralize the Cardiovascular Risk of Unhealthy Dietary Choices?

The title of this post is the exact title of a recent editorial in the American Journal of Cardiology (1). Investigators calculated the “risk for cardiovascular disease associated with the total fat and trans fat content of fast foods”, and compared it to the “risk decrease provided by daily statin consumption”. Here’s what they found:

The risk reduction associated with the daily consumption of most statins, with the exception of pravastatin, is more powerful than the risk increase caused by the daily extra fat intake associated with a 7-oz hamburger (Quarter Pounder®) with cheese and a small milkshake. In conclusion, statin therapy can neutralize the cardiovascular risk caused by harmful diet choices.

Routine accessibility of statins in establishments providing unhealthy food might be a rational modern means to offset the cardiovascular risk. Fast food outlets already offer free condiments to supplement meals. A free statin-containing accompaniment would offer cardiovascular benefits, opposite to the effects of equally available salt, sugar, and high-fat condiments. Although no substitute for systematic lifestyle improvements, including healthy diet, regular exercise, weight loss, and smoking cessation, complimentary statin packets would add, at little cost, 1 positive choice to a panoply of negative ones.

Wow. Later in the editorial, they recommend “a new and protective packet, “MacStatin,” which could be sprinkled onto a Quarter Pounder or into a milkshake.” I’m not making this up!

I can’t be sure, but I think there’s a pretty good chance the authors were being facetious in this editorial, in which case I think a) it’s hilarious, b) most people aren’t going to get the joke. If they are joking, the editorial is designed to shine a light on the sad state of mainstream preventive healthcare. Rather than trying to educate people and change the deadly industrial food system, which is at the root of a constellation of health problems, many people think it’s acceptable to partially correct one health risk by tinkering with the human metabolism using drugs. To be fair, most people aren’t willing to change their diet and lifestyle habits (and perhaps for some it’s even too late), so frustrated physicians prescribe drugs to mitigate the risk. I accept that. But if our society is really committed to its own health and well-being, we’ll remove the artificial incentives that favor industrial food, and educate children from a young age on how to eat well.

I think one of the main challenges we face is that our current system is immensely lucrative for powerful financial interests. Industrial agriculture lines the pockets of a few large farmers and executives (while smaller farmers go broke and get bought out), industrial food processing concentrates profit among a handful of mega-manufacturers, and then people who are made ill by the resulting food spend an exorbitant amount of money on increasingly sophisticated (and expensive) healthcare. It’s a system that effectively milks US citizens for a huge amount of money, and keeps the economy rolling at the expense of the average person’s well-being. All of these groups have powerful lobbies that ensure the continuity of the current system. Litigation isn’t the main reason our healthcare is so expensive in the US; high levels of chronic disease, expensive new technology, a “kitchen sink” treatment approach, and inefficient private companies are the real reasons.

If the editorial is serious, there are so many things wrong with it I don’t even know where to begin. Here are a few problems:

  1. They assume the risk of heart attack conveyed by eating fast food is due to its total and trans fat content, which is simplistic. To support that supposition, they cite one study: the Health Professionals Follow-up Study (2). This is one of the best diet-health observational studies conducted to date. The authors of the editorial appear not to have read the study carefully, because it found no association between total or saturated fat intake and heart attack risk, when adjusted for confounding variables. The number they quoted (relative risk = 1.23) was before adjustment for fiber intake (relative risk = 1.02 after adjustment), and in any case, it was not statistically significant even before adjustment. How did that get past peer review? Answer: reviewers aren’t critical of hypotheses they like.
  2. Statins mostly work in middle-aged men, and reduce the risk of heart attack by about one quarter. The authors excluded several recent unsupportive trials from their analysis. Dr. Michel de Lorgeril reviewed these trials recently (3). For these reasons, adding a statin to fast food would probably have a negligible effect on the heart attack risk of the general population.
  3. “Statins rarely cause negative side effects.” BS. Of the half dozen people I know who have gone on statins, all of them have had some kind of negative side effect, two of them unpleasant enough that they discontinued treatment against their doctor’s wishes. Several of them who remained on statins are unlikely to benefit because of their demographic, yet they remain on statins on their doctors’ advice.
  4. Industrial food is probably the main contributor to heart attack risk. Cultures that don’t eat industrial food are almost totally free of heart attacks, as demonstrated by a variety of high-quality studies (4, 5, 6, 7, 8, 9). No drug can replicate that, not even close.

I have an alternative proposal. Rather than giving people statins along with their Big Mac, why don’t we change the incentive structure that artificially favors the Big Mac, french fries and soft drink? If it weren’t for corn, soybean and wheat subsidies, fast food wouldn’t be so cheap. Neither would any other processed food. Fresh, whole food would be price competitive with industrial food, particularly if we applied the grain subsidies to more wholesome foods. Grass-fed beef and dairy would cost the same as grain-fed. I’m no economist, so I don’t know how realistic this really is. However, my central point still stands: we can change the incentive structure so that it no longer artificially favors industrial food. That will require that the American public get fed up and finally butt heads with special interest groups.

Teenage internet ‘addicts’ at higher risk of depression

Teenagers who are compulsive internet users are more likely to be depressed. Researchers from the School of Medicine in Sydney and Sun-Yat-Sen University in China studied over 1,000 teenagers – who had an average age of 15 – and asked them about their internet use. They found that 6% of the sample felt depressed, moody and anxious when they were not on the internet. Nine months later the teenagers were examined again for signs of anxiety and depression; the ‘pathological’ internet users were two-and-a-half times more likely to show signs of depression.

Diet and ADHD – is junk food a risk factor?

Researchers from the Telethon Institute for Child Health Research in Perth, Australia, have been looking into the links between diet and Attention Deficit Hyperactivity Disorder (ADHD) and have found that children who eat a healthier diet are less likely to develop it. The researchers looked into the diets of 1,800 teenagers and classified them into ‘healthy’ diets – high in fresh fruit, vegetables, whole grains, fish, omega-3 fatty acids, folate and fibre – and ‘Western’ ones which featured more takeaways, sweets and junk food and were higher in total fat, saturated fat, sugar and salt. Having a ‘Western’ diet was found to be linked to a greater risk of ADHD.

Schizophrenics at greater risk in hospital

People with schizophrenia are already known to suffer from worse health than the rest of the population and now a new study from the Johns Hopkins Bloomberg School of Public Health suggests that they may also be more at risk when they go into hospital for treatment. The researchers used data from 2002-2007 which covered 269,387 hospitalizations of people with schizophrenia and 37,092,651 hospitalizations of unaffected people. They found that patients with schizophrenia were more likely to have complications such as pressure sores, infections, blood infections, respiratory failure or pneumonia after surgery, deep vein thrombosis or pulmonary embolism. The researchers put the disparity down to the difficulties people with schizophrenia have in communicating with other people, the fact that nurses and doctors might ignore them if they complained and put this down to their mental-health problem, and the side effects of the drugs that people take for their schizophrenia.

Daughters of alcoholic mums most at risk

Scientists know that the children of alcoholics are at a greater risk of developing mental-health problems but the effects of gender on this process are not really known. Researchers from Yale University used information from the National Epidemiological Survey on Alcohol and Related Conditions to study 40,374 people with and without a history of paternal or maternal alcoholism. They found that the greatest risk was experienced by daughters whose mothers were alcoholics who were more likely to smoke and drink heavily and to suffer from mania and schizoid personality disorder.

Teenage suicide raises the risk of adult wife beating

Boys who try to kill themselves before the age of 18 are much more likely to beat their wives and girlfriends later in life. Researchers from the Oregon Social Learning Center in Eugene studied 153 males from high-crime neighbourhoods who were assessed annually from the ages of 10 to 32. The researchers found that 58% of the participants who tried to kill themselves as children went on to beat their girlfriends/wives compared to 23% among those who had not tried to commit suicide. The association held true even after taking factors such as aggression, depression, substance abuse and a family history of abuse were

PTSD raises dementia risk

Military veterans with post-traumatic stress disorder (PTSD) could be more likely to develop dementia. PTSD often occurs in soldiers coming back from war zones and it is estimated that as many as 17% of veterans coming back from Iraq and Afghanistan have it while between 10-15% of Vietnam veterans had PTSD symptoms 15 years or longer after their return. Researchers from the University of California, San Francisco studied 181,093 veterans, aged 55 or older, over a seven-year period from 2000 to 2007. Over that time 31,107 of them developed dementia. The veterans with PTSD had a 10.6% risk of developing dementia, compared to a 6.6% risk for those without the condition. The study took into account demographic variables and other medical and psychiatric illnesses. PTSD has previously been linked to a range of other medical conditions and declines in cognitive performance.

IQ and suicide risk

Having a low IQ in early adulthood is linked to a higher risk of suicide – at least in men. Researchers from the Wellcome Trust studied 1.1 million men in Sweden who all took IQ tests when they did their national service. Over the next 24 years at least 18,000 of them had had to go to hospital at least once after trying to kill themselves. Even after allowing for age and socioeconomic status men with lower IQ scores were increasingly likely to have attempted suicide at least once, with the most common method being poisoning. The researchers can only speculate on the reasons for this link but two theories are that people with higher IQs have a greater capacity for problem solving and that they find it easier to talk about their problems with other people.
