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)

In a finding likely to reignite debate over proposed new limits on abortion, British researchers have found that years ago, women who terminated a pregnancy increased their risk of giving birth prematurely in subsequent pregnancies, but that with modern procedures the danger has all but vanished. The researchers suggest the shift is the result of a growing use of oral medication to induce or aid in abortion, and a decline in surgical abortions that may injure a woman's cervix. The study looked at 732,719 first births by women in Scotland between 1980 and 2008 and found that during the early 1980s, women who'd had one abortion or more had a higher rate of preterm births during later pregnancies.

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...

This November, voters in San Francisco are expected to weigh in on a controversial topic: whether parents should be allowed to circumcise their baby boys. The proposition, backed by members of an anti-circumcision group that calls its members "intactivists," has ignited heated debate. It's hardly a new issue. Historians have found evidence of circumcision dating to ancient Egypt. Since then, the practice has gone in and out of public favor for myriad reasons, including hygiene, religion, cultural norms and beliefs about masculinity.

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.

With $3 billion in new pledges, world leaders say they believe that an ambitious goal to stop deaths from malaria by 2015 is finally within reach. A plan billed as the most comprehensive ever to tackle the mosquito-borne disease, which kills nearly 1 million people each year, was unveiled last week at a United Nations gathering of heads of government, global health leaders and philanthropists.

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.

The twin plagues of economic hardship and low academic attainment turn out to be an inflammatory problem, not just for society but for the human bodies beset by them. And for many, including those in minority groups who disproportionately experience stunted economic and academic prospects, high rates of Type 2 diabetes are the common result, a new study says. The new research, based on a long-running study of British government workers, offers a partial explanation for a trend that is firmly established in industrialized democracies -- that where calories are plentifully available, those clinging to the lower rungs of the economic ladder are most likely to develop Type 2 diabetes.
