You know the old cliché: Age is only a number. Well now there’s a study that suggests that it’s true; and that age alone isn’t the best predictor of health. I wanted to share some of the study’s findings because, at a time when we are assaulted daily with horrendous and dispiriting news on all fronts, this should give many of us a reason to smile.
Here’s what a large-scale study by a multi-disciplinary team of researchers at the University of Chicago found: psychological well-being, sensory function, mobility and health behaviors are essential parts of an overall health profile that predicts mortality better than age alone. (Italics mine.)
Rather than focus on medical issues, such as heart disease, cancer, diabetes, high blood pressure and cholesterol levels, these researchers came up with a different model of health that considers psychological, social and physical factors, such as mobility. It paints a different picture of how vulnerable – or not — we might actually be.
Demographer and study co-author Prof. Linda Waite said that “some people with chronic disease are revealed as having many strengths that lead to their reclassification as quite healthy, with low risks of death and incapacity.” On the other hand, though, some people considered healthy might have significant vulnerabilities that could affect their mortality or incapacity within five years.
What contributes to those vulnerabilities? Social isolation, as if we hadn’t guessed this before, undermines people’s health. So does poor mental health, like the depression that can accompany social isolation. Poor mental health is said to affect one in eight older adults. Poor sleep patterns, heavy drinking, having a poor sense of smell and walking slowly also undermine health. By contrast, being socially engaged helps keep us healthy, as does staying physically active. Mobility, in fact, is one of the “best markers of well-being,” according to the study.
And here is a not-so-fun fact: Breaking a bone after age 45 is a “major marker for future health issues,” the study concluded.
Among the more interesting – and counterintuitive – findings:
• Cancer itself is not related to other conditions that undermine health.
• Obesity seems to pose little risk to older adults with excellent physical and mental health.
• Older men and women have different patterns of health and well-being during aging (and yes, women tend to live longer).
The study, part of the National Social Life, Health, and Aging Project, supported by the National Institute on Aging of the National Institutes of Health, surveys a representative sample of 3,000 people aged 57 to 85, done by the independent research organization NORC at the University of Chicago.

So let’s get together with our friends and family, take a walk (being careful not to trip and break a bone) and raise a toast (though not too many) to our health. Let’s make sure we can smell the roses. Literally. And on a more serious note, let’s pay attention to what our communities are doing to help ease elders’ loneliness and isolation.
