Mysterious Effects of Smoking May Surface Even 3 Generations Later, Study Finds

The discovery – which scientists claim is one of the "first human demonstrations of transgenerational effects of an environmental exposure across four generations" – suggests ancestral exposures to things like tobacco smoke may have consequences that linger within families undetected for entire generations.



"If these associations are confirmed in other datasets, this will be one of the first human studies with data suitable to start to look at these associations and to begin to unpick the origin of potentially important cross-generation relationships," says epidemiologist Jean Golding from Bristol University in the UK.



In 2014, Golding and fellow researchers assessed data from the Avon Longitudinal Study of Parents and Children (aka, the 'Children of the 90s' study), an observational study of pregnant women and their families, which began in the early 1990s and was initially led by Golding.



The 2014 analysis of questionnaire data from the Children of the 90s study revealed that the sons of fathers who started smoking before they were 11 years old were more likely to have a higher body mass index (BMI) in adolescence, with increased average waist circumference and whole-body fat mass.

Looks like a case of more useless research in search of grant monies. Studies that conclude with "may" are usually shite IMO.

Hmm. Nothing to do with poverty (poor food), chronic stress (poverty, violent parenting), etc., reflected by the fact that the fathers must self-medicate with cigarettes.

The moral of the story is If the sons started smoking when they were 11 like their fathers. they wouldn’t have gotten so fat.

But instead of looking at the smoking. Next time look at what was the fathers metabolism, health, stress and other lifestyle factors at 11 years of to have the need to smoke.

Correlation doesn’t equal causation, I have just heard ray talk about the side effects of vaccines not popping up for a couple of generations and haidut brings up the study of mice being afraid of the smell of cat urine for up to 14 generations after being terrorized by a cat and smelling the urine.
