For half of the world’s population, puberty and the body’s changing hormones means the beginning of periods. For many females, starting their period is a rite of passage that typically occurs around middle school, but the cycle may start much earlier for some, particularly children of color.

According to a new study published in JAMA, menarche — the first period — has occurred steadily earlier and earlier for generations since the 1950s. Researchers examined data collected from 71,341 U.S.-based females born between 1950 and 2005. They observed “significant” trends toward earlier menarche in non-Hispanic Black, Asian, and mixed-race individuals compared with non-Hispanic whites.

“This is important because early menarche and irregular periods can signal physical and psychosocial problems later in life,” lead author Dr. Zifan Wang, a postdoctoral research fellow at Harvard University, told CNN about the study’s findings.

“These trends, he added, “may contribute to the increase in adverse health outcomes and disparities in the U.S.”
