Physical inactivity, we did some calculations using a recent review of the association of physical inactivity with various diseases and we've come up with numbers that are a bit higher than hypertension and high blood cholesterol. It's a bit higher in women because the prevalence data on physical inactivity suggests that women are somewhat less physically active than men. That physical inactivity burden is with cardiovascular diseases, which is reasonably well-known, that if you're not fit you're more likely to get heart disease, but also with some cancers, and with depression and a few other conditions as well. Comparing men to women, depending on how you look at the figures, the difference between men and women is quite extraordinary. I mean, that sounds extraordinary.
Men die younger than women, and that translates into quite a large differential mortality burden.
When you look at the disability burden, the other component of the DALY, the burden for men and women is almost identical, which is really quite surprising. But I guess it ties in with something that we've seen in health surveys that women seem to have high rates of chronic, non-fatal diseases. That's partly because they're living longer into the ages where osteoarthritis, vision loss, Alzheimer's, are very prevalent. And whereas total life expectancy for men now is about 75.5 years, the disability adjusted life expectancy is 69 years. When you start to look at young people, the major causes of burden of disease are injury, with car accidents and suicides being the primary causes there, and mental disorders.
