High Stress and BMI Drive Early Puberty via Repurposed Steroid Pathways in Girls

SUMMARY

A study published in the Journal of Clinical Endocrinology & Metabolism reveals that high body mass index (BMI) and psychological stress interact to accelerate the onset of puberty by over seven months. By mapping the "steroid metabolome," researchers from the Institute for Systems Biology and Columbia University found that stress hormones and androgens—not just estrogen—play a primary role in early breast development and prolonged pubertal timing.
