Want to get people to eat more salad and less junk food? Make vegetables cheaper and soda more expensive. It's not exactly a new idea, but a study out Tuesday offers some fresh support for those in favor of using sin taxes and subsidies to steer people toward a more healthful diet. The study , published online by PLoS Medicine, is a meta-analysis of 32 other studies that use statistical modeling to gauge the impact of various tax and subsidy policies. Overall, it found that consumers buy less of something when the price goes up and they buy more of it when the price goes down.

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.

Women, wouldn't you like to know your precise risk of developing breast cancer, ovarian cancer and endometrial cancer? And wouldn't you like to know what changes you could make in your life to reduce that risk? Researchers from the National Cancer Institute would like to help you. They've just published a study in the journal PLOS Medicine that takes a significant step toward that goal. Ruth Pfeiffer , a senior investigator in the National Cancer Institute's Division of Cancer Epidemiology and Genetics, and colleagues focused on the predictive value of more than a dozen variables, including a woman's body mass index , number of children she has, how long she took birth control pills, whether she used hormone therapy to treat symptoms of menopause, family history of gynecological cancers, and use of cigarettes and alcohol.

Before embarking on a medically invasive, expensive and emotionally taxing effort to get pregnant through in vitro fertilization, it sure would be nice to get a good sense of whether it’s likely to work. After all, only about 1 in 4 attempts resulted in a live birth as recently as 2007. So researchers from England and Scotland scoured data from more than 144,000 IVF cycles in the United Kingdom and looked for factors that might predict which couples stood the best chance of having a baby with assisted reproduction and which faced long-shot odds.

The 2009 H1N1 "swine flu" epidemic killed up to 203,000 people across the globe -- a death toll 10 times greater than initially estimated by the World Health Organization, researchers say. In a study published Tuesday in the journal Plos Medicine, epidemiologists used data on respiratory deaths in 20 nations to calculate a global mortality rate for the pandemic. Prior to this research, the WHO counted just 18,631 lab-confirmed cases of H1N1, a viral infection of the airways.

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...

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)

Researchers have discovered a gene mutation that protects people in Southeast Asia against malaria in much the same fashion that a sickle cell trait protects Africans from the disease. But while the sickle cell protects against the frequently lethal form of the disease caused by the parasite Plasmodium falciparum , the newly discovered gene mutation protects against Plasmodium vivax , which is generally thought to be more benign. Malaria causes an estimated 1 million deaths per year worldwide, and at least half the world's population lives in areas at risk for the disease.

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.
