Early Puberty Tied to Women’s Type 2 Risk
The age at which a girl first gets her period may predict her future diabetes risk. Researchers studied more than 15,000 middle-aged women from eight European countries who were asked when they started their periods. Those who menstruated earliest—between the ages of 8 and 11—had a 70 percent greater risk of developing type 2 diabetes in adulthood than those who began menstruating at an average age of 13. When the women’s adult body mass indexes (a ratio of weight to height) were taken out of the equation, early menstruation was linked to a 42 percent greater risk of developing type 2 diabetes. The researchers surmise that an early onset of puberty somehow directly affects adult diabetes risk, regardless of weight.
