...looked at all sorts of biological markers that could potentially play a role in linking depression and heart disease," says Dr. Mary Whooley, an internist at the VA Medical Center in San Francisco, and lead author of the new study. "We measured all of those, and found that they did not explain the association. All we needed to do was to ask the patient how much they were exercising to be able to explain the link...
Whooley's team studied the depressed group further. Researchers systematically adjusted for each potential risk factor to figure out whether it was mediating the link between depression and heart disease. Physiological factors, such as serotonin levels or CRP, for example, appeared not to have much impact. But when researchers adjusted for physical activity - that is, when they analyzed the data by assuming identical levels of exercise in both depressed and non-depressed patients - the difference in heart disease risk between the groups disappeared. Indeed, inactivity among the depressed patients gave them a 44% greater risk of having a heart event...
...from the Middle East. Given America's checkered standing in the region, it's an alarming figure. In order to avoid being held hostage by fluctuations in the price of crude, the authors recommend developing sustainable energy infrastructures-an endeavor that will also help to suppress climate change. "The link between carbon-intensive activities and changes in the world's climate is now well established, and the consequences will be felt across the hemisphere," the authors write, noting that if "current human activity remains unchanged," the resulting "ecological shocks" could wreak havoc on Central America, the Caribbean, and the southeastern...
