Healthy, Wealthy, and Wise

Just about everyone and his economist mother has researched the ways in which socioeconomic status correlates with health. In the United States, the fraction of people in ‘excellent’ or ‘very good’ health in the top income quartile hovers at around 40 percentage points above that in the bottom quartile. It doesn’t take long to come up with all sorts of theories for this: varying access to health care, poor behavioral habits on the part of the poor, differing environmental factors, differing exposure to stressful events. But no one quite knows for sure.

Anyway, a new RAND paper by James P. Smith looks at this problem in greater detail, trying to figure out which aspects of socioeconomic status actually matter for health. For instance, he looks at the stock market gains during the 1990s—when many people became unexpectedly wealthy—and suggests that income and wealth gains, by themselves, do not decrease the chance of disease onset. This may not be an ideal sample set, though, since those who gained in the stock market were already fairly well-off.

On the other hand, education correlates remarkably well with better health; perhaps in part, Smith suggests, because people with higher levels of education can better manage complicated treatment regiments. An experiment involving a diabetes treatment seems to suggest just that. (Programs that forced patients to stick to the regiment had large health-effects on the less-educated.) But as always, proving causation is another matter—why are educated people, apparently, better at self-management? Maybe they’re more likely to have jobs with more free time. Nevertheless, the “education effect” really is so significant, and persists even into old age.

Two other findings. First, Smith points out that the link between socioeconomic status and health may exist, in part, because the latter causes the former. The onset of a serious chronic disease, after all, really does take a pair of fists to a person’s job and salary. So perhaps the “health gap” causes socioeconomic inequality, rather than the other way around. Second, and more importantly, a growing body of research suggests that economic circumstances during childhood seem to have a serious bearing on health later on in life. Still, no one knows exactly why, although theories abound. The importance of nutrition in the womb is one. Interesting fact: In the olden days, and even among current adults, life expectancy varied significantly with the season of birth. In the northern hemisphere, for instance, 50-year-olds who were born in October and November—and hence, whose mothers had access to cheap and plentiful fruits, vegetables, and eggs during pregnancy—could expect to live about 3/4 of a year longer than those born in the spring. I don’t know if that’s still true for people growing up today, but it might be.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
