Genes Tying Early Sex to Shorter Lifespan, Higher Frailty

Summary

Story summary

Kaixian Wang, lead researcher at Shandong University, found that genes for earlier sexual debut shorten lifespans and raise frailty.
The genes correlated with shorter lifespans, higher frailty index scores and lower healthy-aging scores.
Four mediators—frailty, depression, COPD and ADHD—each explained over 20 % of the negative aging effect.
The authors called the modest rise in self-rated health a statistical artifact and urged education and screenings for early initiators.
