First Dibs on Diabetes for Elder Sibs?

First-born kids may have a greater risk for future type 2 diabetes. Researchers studied 85 children between the ages of 4 and 11 and found that though first-borns were thinner and taller than younger siblings, they were also 21 percent less insulin sensitive and had higher blood pressure. The finding is important because decreased insulin sensitivity is tied to type 2 diabetes. The study's authors say changes that occur to the uterus after a first pregnancy and result in better nutrient flow for subsequent babies might explain the difference.
