While earlier menarche trends have been noted in the US, there\u2019s limited data on differences based on sociodemographic factors and body mass index (BMI). Additionally, the time from menarche to cycle regularity is another aspect with health implications that hasn\u2019t been studied much.\n</p><p>Results showed a decrease in the mean age at menarche over time, with more people experiencing early menarche and fewer reaching regularity within 2 years. The trend toward earlier menarche was stronger among certain racial and ethnic minority groups and those with low socioeconomic status.\n</p><p>Exploratory analysis suggested that BMI explained a significant portion of the temporal trend in age at menarche.
