Researchers at U-M C.S. Mott Children's Hospital say increasing rates of childhood obesity and overweight in the United States may be contributing to an earlier onset of puberty in girls. In a study published this month in Pediatrics, they found that higher body mass index (BMI) score in girls as young as age 3, and large increases in BMI between 3 years of age and first grade are associated with earlier puberty.

   Researchers from the Monell Center have for the first time attempted to count the number of genes that contribute to obesity and body weight. The findings suggest that over 6,000 genes -- about 25 percent of the genome -- contribute to help determine an individual's body weight. This high degree of complexity suggests that a quick fix to the obesity problem is unlikely.

   A common virus may cause obesity in some people, according to new evidence in a controlled laboratory study. Scientists showed that infection with human adenovirus-36, long recognized as a cause of respiratory and eye infections in humans, transforms adult stem cells obtained from fat tissue into fat cells. The study, which might lead to new treatments for obesity, will be reported in August at the American Chemical Society national meeting in Boston.
