The age at which a girl has her first interval can provide priceless clues about her long-term danger for situations like weight problems, diabetes, coronary heart illness and reproductive well being points, in accordance with a examine being introduced Sunday at ENDO 2025, the Endocrine Society’s annual assembly in San Francisco, Calif.
The Brazilian examine discovered that each early and late menarche—the age when ladies first get their interval—are linked to completely different well being dangers. Girls who had their first interval earlier than age 10 had been extra prone to develop weight problems, hypertension, diabetes, coronary heart issues and reproductive points like pre-eclampsia later in life. Girls who began their interval after age 15 had been much less prone to be overweight however had a better danger of menstrual irregularities and sure coronary heart situations.
“We now have evidence from a large Brazilian population that confirms how both early and late puberty can have different long-term health impacts,” mentioned examine writer Flávia Rezende Tinano of the College of Sao Paulo in Sao Paulo, Brazil.
“While early menarche increases the risk for multiple metabolic and heart problems, late menarche may protect against obesity but increase certain heart and menstrual issues. Most women can remember when they had their first period, but they might not realize that it could signal future health risks. Understanding these links can help women and their doctors be more proactive about preventing conditions like diabetes, high blood pressure and heart disease.”
Tinano mentioned the examine is without doubt one of the largest of its type in a growing nation, offering priceless knowledge on a subject that has largely been studied in wealthier international locations. “It highlights how early and late puberty can affect a woman’s long-term health, especially in underrepresented populations like those in Latin America,” she mentioned.
The examine was a part of the Brazilian Longitudinal Research of Grownup Well being (ELSA-Brazil) and evaluated knowledge from 7,623 ladies ages 35 to 74. The age of their first interval was categorized as early (lower than 10 years previous), typical (ages 10 to fifteen) or late (older than 15). They assessed the ladies’s well being by way of interviews, bodily measurements, lab exams and ultrasound imaging.
The examine is titled, “Early and Late Age at Menarche and their Distinct Cardiometabolic and Reproductive Outcomes: The Brazilian Longitudinal Study of Adult Health,” and it is going to be introduced on Sunday, July 13.
“Our findings suggest that knowing a woman’s age at her first period can help doctors identify those at higher risk for certain diseases,” Tinano mentioned. “This information could guide more personalized screening and prevention efforts. It also emphasizes the importance of early health education for young girls and women, especially in developing countries.”
