Soda Habit May Prompt Early Puberty in Girls, Study Suggests

TUESDAY, Jan. 27, 2015 (HealthDay News) — Girls who consume a lot of sugary drinks may enter puberty earlier than girls who don’t, Harvard researchers report.
Among nearly 5,600 girls aged 9 to 14 who were followed between 1996 and 2001, the researchers found that those who drank more than 1.5 servings of sugary drinks a day had their first period 2.7 months earlier than those who drank two or fewer of these drinks a week.
This finding was independent of the girls’ body mass index (a height-weight ratio that measures body fat), how much food they ate, or whether they exercised or not, the researchers noted.
“Starting periods early is a risk factor for depression during adolescence and breast cancer during adulthood. Thus, our findings have implications beyond just starting menstruation early,” said study first author Jenny Carwile, a postdoctoral associate at the Harvard School of Public Health, in Boston.
The researchers found that the average age at the first period among girls who consumed the most sugary drinks was 12.8 years, compared with 13 years for those drinking the least.
The reasons why sugary drinks might bring on menstruation early are not clear, she said. “We think it may have to do with the effects of consuming a highly sugared food,” Carwile said.
