Children of men who smoked during puberty may age faster: Study
Study shows offspring of fathers who smoked at age 15 or younger age 9 to 12 months biologically faster, with greater effects if offspring also smoked, researchers say.
- Research shared on September 29, 2025, at the ERS Congress in Amsterdam indicates that individuals whose fathers smoked during their early teenage years may experience accelerated biological aging.
- Researchers explored whether paternal smoking during puberty alters sperm epigenetic material, potentially causing faster biological ageing in future offspring.
- The study examined blood samples from 892 people aged 7 to 50 across Europe and Australia to assess DNA markers of ageing called epigenetic clocks.
- Results showed people whose fathers started smoking at 15 or younger had biological ages 9 to 15 months older than their chronological ages, especially if they had smoked themselves.
- Experts urged stronger prevention of adolescent smoking as it causes diseases and harm that can persist across generations, stressing the need to keep children from starting smoking.
