A population approach to obesity reduction

On studying not quite the right thing (an issue of categories and associations).

a new consideration for epidemiologists trying to study a phenomenon

This article speaks to the contrast Geoffrey Rose drew, but extended beyond the arena of population health. "Real reductions in drug supply and demand will come through improving public health and safety, strengthening anticorruption measures - especially those that combat money laundering - and investing in sustainable development. We also believe that the smartest pathway to tackling drugs is decriminalizing consumption and ensuring that governments regulate certain drugs, including for medical and recreational purposes. "

One person's quest to tackle a rare disease, not typically the subject of social epidemiology. Is there, however, something to learn from his approach?

"The link between air pollution and dementia remains controversial-even its proponents warn that more research is needed to confirm a causal connection and work out just how the particles might enter the brain and make mischief there. But a growing number of epidemiological studies from around the world, new findings from animal models and human brain imaging studies, and increasingly sophisticated techniques for modeling PM2.5 exposures have raised alarms. Indeed, in an 11-year epidemiological study to be published next week in Translational Psychiatry, University of Southern California (USC) researchers will report that living in places with PM2.5 exposures higher than the Environmental Protection Agency's standard of 12 μg/m3 nearly doubled dementia risk in older women. If the finding holds up in the general population, air pollution could account for roughly 21% of dementia cases worldwide,"
