Even people with a strong genetic predisposition to obesity can offset their risk of being overweight by being physically active, according to a study published Tuesday in the journal PLoS Medicine . British researchers examined the effects of 12 genetic variants associated with a higher risk of obesity among 20,430 people in Britain. Researchers calculated a genetic predisposition score for each volunteer that ranged from 0 to 24, representing the number of obesity-related variants they had inherited.

For most of us living in the developed world, diarrhea is an uncomfortable nuisance -- not a life-threatening event. But each year for more than a million children under the age of 5, it is a killer. It's known that a few simple precautions and treatments can make a difference and save a child. What's been unknown, say researchers led by Christa Fischer Walker of the Johns Hopkins School of Public Health, is whether providing those interventions makes a difference on a large scale, cutting disease and death rates around the globe.

Abilify, the brand name of the drug aripiprazole, is an antipsychotic medication used to treat the acute phase of bipolar disorder as well as the maintenance phase -- the period of time after a patient has improved and the focus turns toward preventing a relapse. This second use of Abilify is the target of a biting review published Tuesday by Dr. Alexander Tsai of Harvard University and Dr. Nicholas Rosenlicht of UC San Francisco. The scientists set out to review data that justify the use of Abilify for the maintenance phase of bipolar disorder -- and found very little.

Want to gauge your risk for developing Type 2 diabetes? Don't just step on the scale - reach for a measuring tape too, a new study suggests. The circumference of your waist can tell you a lot about your chances of getting diabetes, according to a study published Tuesday in the journal PLoS Medicine . Health providers usually rely on body mass index to determine patients' diabetes risk, but adding waist circumference to the equation would...

Treatment drugs can do more than improve the health of people with HIV: If administered early, medications can also reduce the spread of the disease to sexual partners and may help stem the AIDS epidemic. But many logistical hurdles stand in the way of making this strategy feasible, affordable and effective, according to experts writing in Tuesday's edition of the journal PLoS Medicine. The medications in question are antiretroviral therapies, which prevent HIV from multiplying and drastically diminish the amount of virus circulating in the blood.

These days, it's just good to have a job. But remaining gainfully employed can take a toll on health, especially if your work has you up at odd hours and sleeping irregularly. Shift work, say two studies out this week, poses particular problems for women, who appear to be at greater risk of Type 2 diabetes and possibly breast cancer if they maintain work schedules that mess with their internal clocks. Researchers have uncovered a host of links between humans' respect for their circadian rhythms and their health prospects.

It will be an even 20 for Michelle and Jim Bob Duggar, who announced Tuesday that they're expecting their 20th child. The Duggars, stars of their own TLC show, are a source of fascination for some people, since super-sized families aren't the norm the way they were about a century ago. Michelle Duggar, you'll recall, didn't have such an easy time around with her last pregnancy in 2009. Daughter Josie was delivered early when it was discovered that Michelle had preeclampsia and gall bladder problems (Josie is now doing fine)

Multinational food corporations have a growing influence on the health of people around the world, including obesity, and their actions need greater scrutiny, according to an editorial Tuesday in the journal Public Library of Science Medicine. The editorial kicks off the journal's three-week series looking at what it calls “Big Food.” The first articles, and the editorial, criticize not just the food companies but also officials charged with protecting public health. “The big multinational food companies control what people everywhere eat, resulting in a stark and sick irony: one billion people on the planet are hungry while 2 billion are obese or overweight,” the editorial says.

Taking folic acid supplements for a year before conception reduces the risk of very premature birth by at least 50%, researchers reported Monday. Shorter courses of the supplement were not as effective, according to the study of nearly 35,000 women reported in the Public Library of Science journal PLoS Medicine. Folic acid's effectiveness in reducing the risk of neural-tube and other birth defects -- even without such a long course -- is long established.
