Body fat and smoking are linked, UK study finds

Women and girls whose grandfathers or great-grandfathers started smoking cigarettes at a young age tend to have more body fat, according to a new British study that used data from a project decades-long multi-generational research project called “Children of the 90s.

The new study from the University of Bristol asked researchers to test whether exposure of men to certain chemicals before the conception of an offspring could have effects on said offspring, in this case, if smoking prepubescent by the Male ancestors would affect participants in “Kids of the 90s,” which encompasses thousands of topics.

The original cohort of the “Children of the 90’s” study consisted of 14,000 pregnant women who agreed to participate in the research along with their children and grandchildren. The project has just celebrated its 30th anniversary.

Previous research in 2014 found that if a father started smoking regularly before he reached puberty, measured in this case at age 11, then his sons, but not his daughters, had more body fat than expected.

However, the new research determined, through analysis of previous male generations (grandfathers and great-grandfathers) of study participants of 90s children, that women also had higher body fat. high if their grandfathers or great-grandfathers had started smoking before the age of 13. compared to those who started smoking later in childhood, between the ages of 13 and 16. No effects were seen in male offspring, according to the study.

“This research brings us two important results. First, that before puberty, a boy’s exposure to particular substances can have an effect on subsequent generations. Second, one of the reasons children become overweight may not have to do with their current diet and exercise so much as it does with the lifestyle of their ancestors or the persistence of associated factors over time. years,” said the study’s lead author, Jean Golding, in a release.

“If these associations are confirmed in other data sets, this will be one of the first human studies with appropriate data to begin to examine these associations and to begin to unpack the origin of potentially important intergenerational relationships,” said she continued.

Further research will be needed to confirm the study results in other long-term studies and to extend investigations to other conditions that affect multiple generations.
