Your Health: June 1

Nursing home residents may be more likely to carry a form of multi-drug-resistant bacteria! Researchers reviewed eight studies on those infections, finding on average, one out of four nursing home dwellers were carriers of them. The team notes people in nursing homes often have health conditions that weaken their immune systems and they are often on prolonged antibiotic use, which contributes to resistance of these drugs. Their work appears in the American Journal of Infection Control.

Preschoolers who can recognize foods, either by name or by logo, may be more likely to be obese. A study in the journal Appetite measured the body mass index (BMI) of more than 200 young children. All were asked to identify 30 different U.S. food brands. Overweight children were able to recognize more of these items than kids of a healthy weight. Further research is needed, as variables such as watching TV or family demographics were not considered.

And finally, research in the Proceedings of the National Academy of Sciences discovered our senses of sight and smell may keep us away from people who are sick. Researchers studied a group of people looking at pictures and videos and examining odor samples of a group of healthy people and those who appeared to be sick -- finding people tended to shy away from those who looked like their immune system was compromised. Study authors say their work provides biological confirmation that survival instincts help us avoid infection.
