(May 28, 2008 - Insidermedicine) From Atlanta - The epidemic of childhood obesity may have finally hit a plateau. According to data collected between 1999 and 2006, the rates of overweight or obese children have not increased since 1999. The researchers point out that 32% of American schoolchildren are still overweight or obese, and thus represent an entire generation that could be struggling with weight-related health issues in the years to come.

From Boston - A molecule derived from a bacteria may lead to the treatment of inflammatory bowel diseases like ulcerative colitis and Crohn's disease. Research published in Nature shows that a polysaccharide produced by Bacteroides fragilis, a typical gut bacterial strain, protected rats with a form of inflammatory bowel disease. The polysaccharide works by stimulating interleukin-10, a natural anti-inflammatory agent, which dampens the immune system.

And finally from Hong Kong - Exposure to second hand smoke early in life raises the risk for both respiratory and other types of infections, according to research published in Tobacco Control. In a study of over 7,400 children, those who lived in the household of someone who smoked near them frequently within the first 3 months of life were at risk for developing respiratory infections and meningitis. Exposure during the first 6 months of life raised the risk by 45%.
