More guns and less education is a prescription for poor health

Within the span of one week, my state of Kansas was headlined in two pieces in the New York Times, unusual for a small state. Unfortunately, neither was meant to be complimentary. “What’s the matter with Kansas Schools?” by David Sciarra and Wade Henderson appeared as an op-ed on January 8, 2014, and “Keeping Public Buildings Free of Guns Proves Too Costly for Kansas Towns”, by Steve Yaccino, was a news article (middle of the main section but top of the web page!) on January 12. Both are political and social issues; for example, the thrust of the “guns” article is that Kansas municipalities (like Wichita) that want to keep guns out of public buildings (like the library) are financially stymied by the cost of the security requirements the legislature has put in place in areas where carrying guns is not permitted. Like abortion (and neither of these pieces addresses Kansas’ virulent anti-abortion laws), guns are a very hot-button issue that inflames deep-seated passion in places like Kansas, and so is (sometimes) education. I will, however, focus my comments on the health impacts of these laws.

First, guns. Guns are, very simply, bad for people’s health. (Obviously, even when used as “intended”, for hunting, they are bad for some animals’ health, but this is not my focus.) Having guns around increases the risk of death or injury from them. Having guns intended for hunting stored locked and unloaded is the safest, but this doesn’t work for guns intended for self-defense since that renders them less available for that purpose. Carrying guns on your person, in your car, in public, on the street, and into businesses, public buildings, schools, and health care settings increases the risk. This is not what gun advocates, and concealed-carry advocates believe. Their idea is that there are bad guys out there carrying guns, either criminals who might want to rob you or crazy people who might want to shoot up your school or post office, and that carrying a gun allows one to protect oneself, and possibly others, by shooting down the perpetrator before more damage can be done. Thus, it protects your health, and that of others.

Nice idea, but completely unsupported by the facts.  Guns kill lots of people, injure many more, and virtually never save lives. This is the case even when used by police, and even more true when use of guns by police officers is excluded. It is true despite the widely-publicized, often repeated on the internet, and frequently invented stories about a virtuous homeowner shooting an armed robber. I have no doubt that such cases occur, but with such rarity as to be smaller than rounding error on the number of deaths and serious injuries inflicted by guns.  Suicides and homicides are among the leading causes of death in the US, most are caused by guns, and almost none of the homicides are “justifiable manslaughter” from a person protecting him/herself from an armed invader. The mere presence of easy-to-access guns in the environment increases dramatically the risk of successful suicide (see my blog, Suicide: What can we say?, December 12, 2013, with data from David Hemenway’s “Private Guns, Public Health”[1]). In addition, the number of “accidental” deaths (where someone other than the intended victim was shot, or someone was shot when the intent was “just” to threaten or show off, or by complete accident, sometimes when an unintended user – say a child – gets hold of a loaded gun) from guns is way ahead of any other method of harm (knives, bats, etc.)

When we go beyond having guns to carrying guns in public places, the data is less well collected. However, the trope of the heroic law-abiding, gun-carrying citizen drawing down on the evildoer in a public place, like say a movie theater or the waiting room of your clinic, is a terrifying thought. First of all, almost none of them are Bat Masterson or Wyatt Earp or Annie Oakley (except maybe in their own minds) and the idea that they will hit who they are aiming at is wishful thinking; the rest of the folks are caught in a gunfight. It is scary enough when this involves police officers, but if half the waiting room pulls out pieces, the results will be, um, chaotic. Harmful. Not to mention what happens when the police show and don’t know who to shoot at (maybe if you are a gun-toting good guy you can wear a white hat…).

So, having guns around, and the more easily they are available, is absolutely harmful to the health of the population, and generally you as an individual. If people, including legislators, and Kansas legislators in particular, want to encourage gun carrying for other reasons, they should at least be aware of and acknowledge the health risks. But what about education? The cuts in state education will, quite likely, harm the education of children (or if, as the article notes, the state Supreme Court forces the legislature to fund K-12, the education of young adults since the money will likely come from higher education), but what about health?

There is a remarkable relationship. More education leads to better health. Better educated people are healthier. The relationship is undoubtedly complex, because better educated people also have better jobs and higher incomes, which is also associated with health. This is addressed with great force in a recent policy brief “Education: It Matters More to Health than Ever Before”, by the Virginia Commonwealth University Center for Society and Health sponsored by the Robert Wood Johnson Foundation; for example, while lifespan overall in the US continues to increase, for white women with less than 12 years of education, it is currently decreasing! The RWJ site also includes an important interview with Steven Woolf, MD MPH, Director of the Center. “I don’t think most Americans know that children with less education are destined to live sicker and die sooner,” Dr. Woolf says. He discusses both the “downstream” benefits of education: “getting good jobs, jobs that have better benefits including health insurance coverage, and higher earnings that allow people to afford a healthier lifestyle and to live in healthier neighborhood,” and the “upstream” issues, “factors before children ever reach school age, which may be important root causes for the relationship between education and health. Imagine a child growing up in a stressful environment,” that increase the risk of unhealthy habits, poor coping skills and violent injuries.

In several previous blogs I have cited earlier work by Dr. Woolf, one of the nation’s most important researchers on society and health, notably in "Health in All" policies to eliminate health disparities are a real answer, August 18, 2011. I included this graph, in which the small blue bars indicate the deaths averted by medical advances (liberally interpreted) and the purple bars represent the potential deaths that could be averted if all Americans had the death rates of the most educated. I also included a link to the incredible County Health Calculator (http://chc.humanneeds.vcu.edu) which allows you to look at any state or county, find out how the education or income level compares to others, and use an interactive slider to find out how mortality and other health indicators would change if the income or education level were higher or lower.

In the US, the quality of one’s education is very much tied to the neighborhood you live in, since much of school funding is from local tax districts and wealthier communities have, simply, better schools. (This last is completely obvious to Americans, but not necessarily to foreigners. A friend from Taiwan was looking at houses and was told by the realtor that a particular house was a good value because it was in a good school district. She called us an asked what that meant; “In Taiwan, all schools are the same; they are funded by the government. No one would choose where to live based on the school.”) This difference could be partially compensated for by state funding for education, which is why cuts in this area are particularly harmful, including to our people’s health. In fact the most effective investment that a society can make in the health of its people is in the education of its young.

An educated population is healthier. Wide availability and carrying of guns decreases a population’s health. Unfortunately, the public’s health seems to carry little weight in these political decisions.

Health Disparities

Etiologic Agent	# deaths per year
Tobacco use	400,000
Diet/activity	300,000
Alcohol	100,000
Microbial agents	90,000
Toxic Agents	60,000
Firearms	35,000
Sexual behaviors	30,000
Motor vehicles	25,000
Illicit use of drugs*	20,000

What are some of the components of the social determinants of health? They include, certainly, housing, food, warmth, education, the overall treatment of women and especially the education of women. There is evidence that greatest determinant of the quality of a society, and especially its economic standing, is related to the education of women. Let us take the example of “food deserts”. 2.3 million (2.2%) of continental US households are more than a mile from a supermarket and do not have access to a vehicle. There are food deserts not far from me in Kansas City, KS. In a community called “the Argentine”, largely populated by Mexican Americans, it can take more than two hours on 3 buses to reach the supermarket. It could be faster to walk, but hard to carry back groceries. In fact, the inability to carry much on any one trip can lead to fresher food, but this requires availability of stores. In an article in the NY Times (July 31, 2011), Russell Shorto describes “The Dutch way: bicycles and fresh bread”; riding bicycles everywhere not only provides great exercise, but the limited carrying capacity means that the bread – and other food – is fresh daily.

The unequal distribution of the social determinants of health is a major cause of health disparities, as demonstrated in the slides from Dr. Jones, and in a few from Dr. Woolf.  The latter shows us a list of the 9 most common etiologies of death, from tobacco use (400,000 deaths per year) through illicit drugs (20,000, and not including the use of “licit”, legally prescribed, drugs). Seen this way, by root cause (that is “tobacco”, “diet and activity”, “alcohol”) as opposed to medical diagnosis (like “heart disease”, “cancer”, “liver disease”) we get a clearer picture of the true role of social determinants. Only one on the list, (#4, microbial agents) is even considered part of “traditional” medicine. Dr. Woolf also demonstrates the tremendous impact that education has on health with data from the University of California San Francisco (UCSF) Center for Health Disparities that show that 26.7% of those with less than a HS education describe themselves as having “fair” or “poor” health, compared with 5.8% of college graduates, a five-fold difference! The racial and gender difference in age-adjusted mortality rates is also dramatic; the death rate for black males is coming down, but still far exceeds white males and black and white females (and, although the rates for women are lower than for men, they are much higher for black women than for white women).

In a provocative “thought experiment” published in the American Journal of Public Health, “Giving everyone the health of the educated: an examination of whether social change would save more lives than medical advances”[1], Dr. Woolf and his colleagues demonstrate that even if we attribute all current and recent reduction in mortality to medical advances (nowhere near true; most are due to the types of societal change generally characterized as “public health”, such as clean water, sanitation, and cleaner air), eliminating the disparities that exist on the basis of educational level would dwarf that change, as shown in this graphic.

The County Health Calculator produced by Woolf and colleagues from Virginia Commonwealth University, and available free on line,  allows one to look at the socioeconomic status (measured as percent of people with income s >200% of poverty) and education (measured as percent of people with at least some college) for every state and county, and compare it to the other states or counties within a state. A neat “slider” feature allows you to change these rates (e.g., make the rate the same as the best or worst) and see what the change in deaths would be. For Harris County, Texas (Houston) , if 5% more people attended some college and 5% more had an income higher than twice the federal poverty level we could expect to save 1,200 lives, prevent 12,200 cases of diabetes, and eliminate $97.8 Million in diabetes costs every year.

Bradley and Taylor, in an Op-Ed piece in the NY Times, “To fix health care, help the poor”, NY Times, (12/8/11) cite their research challenging the simplicity of the notion that the US spends far more per capita on health care than other developed countries. While true on its face, the US spends far less on social services that might decrease the need  for health care; when lumped together, the difference decreases, although the US stands out as being one of very few countries where almost all health+social services spending is on medical care. [2]

A major way to address social determinants and health disparities is the implementation of “health in all” policies, for such things as

·         Land use (what is the density? Are there open spaces? How is space used?)

·         Built environment (are distances to schools and shopping walkable? Are there facilities for exercise?)

·         Transportation (can people get to the store or the park?)

·         Agriculture (what about antibiotic and drug use in raising livestock? How about the conditions of farmworkers, including exposure to pesticides?)

·         Environmental Justice (are there toxins in the environment? Lead? Who is exposed to “brownfields” and do their children have higher rates of cancer? )

·         Health policies (smoking in public places)

·         Taxes (do these encourage or discourage the building of a healthful society?)

Although these areas are outside of traditional medicine, physicians can be involved in addressing them; they are (like Dr. Henry A. Withers, for whom this lecture is named) community leaders who have great moral authority.
