Smoking, Fractures And Ligament InjuriesCigarette smoking, which causes over 8.6 million illnesses annually in the U.S., has been shown to have harmful effects on a variety of orthopedic conditions. Studies have shown that the numerous toxins contained in cigarette smoke can undermine fracture and ligament repair following injury. In addition, smokers have higher rates of hip fracture, fracture healing problems and bone infections and smoking has been shown to impair soft tissue........Go to the Rheumatology news blog (Added on 11/7/2006 4:41:46 AM)

Children's Belly Fat Increases More Than 65 PercentAbdominal obesity increased more than 65 percent among boys and almost 70 percent among girls between 1988 and 2004. The finding of growing girth is significant because abdominal obesity has emerged as a better predictor of cardiovascular disease and type 2 diabetes risk than the more usually used Body Mass Index, a weight to height ratio that can sometimes be misleading.
As the first nationally representative study to document the increase........Go to the Weight watcher's blog (Added on 11/6/2006 4:32:15 AM)
