flag Fathers who smoked during puberty may accelerate their children's biological aging by up to a year, a study finds.

flag A study presented at the European Respiratory Society Congress finds that people whose fathers smoked during puberty may age faster biologically, with offspring showing a nine-month to one-year biological age increase on average. flag The research, led by Dr. Juan Pablo López-Cervantes, analyzed blood samples from 892 individuals using epigenetic clocks to measure biological aging. flag The effect was strongest when fathers began smoking at age 15 or younger and increased if the participants themselves smoked. flag No significant link was found for maternal smoking before pregnancy. flag Researchers suggest smoking during adolescence may alter sperm epigenetics, potentially passing accelerated aging effects to children. flag The findings highlight long-term health risks, including higher disease risks, and underscore the need for stronger youth tobacco and vaping prevention efforts despite declining traditional smoking rates.
