🩺 Age of first period is an indicator of future health

The timing of first menstruation may reveal long-term health risks. A Brazilian study highlights surprising links between puberty and certain adult pathologies.


This research, presented at the annual Endocrine Society meeting, analyzes the consequences of early or late puberty. The results show clear correlations with metabolic, cardiovascular and reproductive disorders.

Differential risks depending on age of first period

Women who had their first period before age 10 show increased risk of obesity, diabetes and hypertension. These associations persist into adulthood, according to data collected from 7,623 Brazilian women.

Late menstruation, after age 15, appears paradoxically protective against obesity. However, it may increase the likelihood of menstrual disorders and certain heart conditions.

This study, part of the ELSA-Brazil project, combines clinical exams and medical imaging. It confirms trends observed in wealthy countries, but with specificities unique to Latin American populations.

Towards more targeted preventive medicine

The authors suggest integrating this biological indicator into health assessments. A simple question about age at first period could help identify at-risk patients.

The University of São Paulo team advocates for tailored health education campaigns. Affected young girls could benefit from enhanced medical monitoring.

This approach is particularly relevant in developing countries. Healthcare systems could thus anticipate certain chronic diseases using an easily accessible marker.
