The research, from the Children of the 90s study at the University of Bristol, found that, on average, that the sons whose father smoked from a young age, had 5kg to 10kg more body fat than their peers by the time they reached their teenage years.
Those behind the findings suggest this could indicate that exposure to tobacco smoke before the start of puberty may lead to metabolic changes in the next generation.
Interestingly, the effect was not found to the same degree in daughters.
Other factors were also taken into account for the study, such as genetic factors and the father's weight, but none of these explained the change. In fact, the fathers who started smoking before the age of 11 tended to have a lower Body Mass Index (BMI) on average.
The study claims that the effect was not seen in the sons of men who started smoking after the age of 11, suggesting that the period before the start of puberty is a particularly sensitive time for environmental exposures.
Of the 9,886 fathers who took part in the research, 54% (5,376) were smokers at some time – and of these men, 3% (166) reported smoking regularly before the age of 11. When measured at the ages of 13, 15 and 17, the sons of the men in the latter category had the highest BMIs at each time point, when compared with the sons of men who had started smoking later or who had never smoked. Specifically, the boys had higher levels of fat mass (recorded using whole-body scans), ranging from an extra 5kg to 10kg between the ages of 13 and 17.
The findings have been published in the European Journal of Human Genetics, and senior author, Professor Marcus Pembrey, said: "This discovery of trans-generational effects has big implications for research into the current rise in obesity and the evaluation of preventative measures. It is no longer acceptable to just study lifestyle factors in one generation.
"We are probably missing a trick with respect to understanding several common diseases of public health concern by ignoring the possible effects of previous generations."
Professor David Lomas, Chair of the Medical Research Council (MRC), who funded the research, added: "Population studies have provided a wealth of information about health and disease, including first identifying the link between smoking and cancer more than 60 years ago.
"This research clearly demonstrates that such studies have so much more to give, which is why it's vital that the future potential of cohorts and the studies they make possible is not jeopardised by the proposed EU data regulations."

Men Who Smoke At A Younger Age 'Have More Obese Sons'
A new study has claimed that men who started smoking regularly before the age of 11 had sons who were more likely to be obese.The research, from the Children of the 90s study at the University of Bristol, found that, on average, that the sons whose father smoked from a young age, had 5kg to 10kg more body fat than their peers by the time they reached their teenage years.
Those behind the findings suggest this could indicate that exposure to tobacco smoke before the start of puberty may lead to metabolic changes in the next generation.
