"Study Reveals U.S. Girls Starting Periods Earlier, Irregular Cycles Persist"

A new study reveals that girls in the U.S. are getting their first periods about six months earlier on average than in the 1950s and '60s, with more girls starting menstruation before age 9. Factors such as obesity, stress, and endocrine-disrupting chemicals are likely contributing to this trend. Early menstruation is linked to several health risks, including higher chances of cardiovascular disease and certain cancers. Parents are advised to prepare for earlier menstruation by promoting healthy diets, regular physical activity, and adequate sleep for their children.
