Fathers’ tobacco use linked to metabolic changes in their children

Why it matters: Paternal smoking may seed diabetes risk in the next generation.
- The Endocrine Society published the study linking paternal nicotine to offspring metabolic changes.
- Raquel Chamorro‑Garcia, Ph.D. (UC Santa Cruz) reports lower insulin in female pups and altered liver function in male pups of nicotine‑exposed fathers.
- CDC data underscore the urgency, with 40.1 million Americans living with diabetes, a disease that could be amplified by paternal smoking.
- Male smokers emerge as a key prevention target, as they use tobacco more often than women.
- Female offspring showed reduced fasting glucose and insulin, while male offspring displayed liver dysfunction, hinting at sex‑specific effects.
A mouse study published by The Endocrine Society shows that fathers’ nicotine exposure reprograms offspring metabolism—lowering insulin and glucose levels and altering liver function—pointing to a hidden paternal pathway that could elevate diabetes risk in the next generation.
