There have been similar studies on male fitness level at the time of conception.
There is growing scientific evidence in human and animal studies that should inspire every father-to-be to start exercising more and eating healthier before conceiving a baby. A wide range of studies have found that fathers who are obese at the time of conception pass on a predisposition to their children and grandchildren to be overweight, to develop diabetes, or both.

Most of those high-level epigenetics findings are on shaky ground.
Even if true that their children had higher rates of obesity this could easily be due to nurture - e.g. those Mothers could've been more likely to stock up on food at home and feed their children more due to the trauma, with the methylation explanation being post-hoc.

>Other studies have looked at the effect of famine. When mothers were exposed to famine during pregnancy, as was the case in Holland in 1944 and 1945, their children had a higher incidence of obesity and coronary disease compared to mothers not exposed to famine. The higher risks were traced to reduced DNA methylation of a gene producing an insulin-like growth factor. Such epigenetic effects can be inherited over several generations. >Exposure of parents to cocaine may affect memory.
I can't find evidence of it, but it seems reasonable to extrapolate that long term life style choices will also affect epigenetics for the better.
