As people around the globe continue to get fatter, diabetes rates will continue to rise and insulin supplies will be in short supply, a study warns. By 2030, an estimated 79 million adults with Type 2 diabetes are expected to need insulin. But if current quantities remain level, as many as 40 million sufferers could be left without it, said a report in the journal The Lancet Diabetes and Endocrinology.

Children move less starting at age 6

Most experts believe that physical activity declines as children reach adolescence, but a new study has found that the decline begins as early as age 6. Researchers measured physical activity at ages 6, 8 and 11 in 600 European children wearing activity trackers. The scientists found that average time spent in physical activity declined by about 75 minutes a day by the time the children were 11. The study, in Pediatrics, found that at age 11, the children were spending an average of almost two more hours a day in sedentary behavior — essentially, sitting still — than they were at 6. Only 63 percent of 11-year-olds were getting the recommended 60 minutes a day of moderate to vigorous exercise, compared with 82 percent of 6-year-olds.
