As a follow up on the descendant study from China, your link shows that children with a mother that experienced childhood famine have an average BMI that is higher by ~1. Children with fathers who experienced childhood famine actually have a lower BMI. This study doesn't control for the obvious cultural and behavioral implications of a parent living through the famines, although epigenetic connections have been proposed elsewhere [0] Here [1] is another study from China That shows that simply having an obese parent is the single biggest factor in a developing childhood obesity, and nearly doubles the obesity risk. I didnt bother digging up a study, but this link[2] says that in the USA, a child with 1 obese parent has a 50% chance of being obese (absolute, not increased hazard ratio!) If both parents are obese, a child has an 80% chance of being obese! This makes a lot of intuitive sense to me. I would expect the modeled behavior, status, household food, and parenting to have a huge impact on children. This naturally overshadows the interesting but tiny impact of epigenetic transmission. https://pmc.ncbi.nlm.nih.gov/articles/PMC8648067/ https://pmc.ncbi.nlm.nih.gov/articles/PMC8648067/ https://link.springer.com/content/pdf/10.1186/s12199-021-00973-x.pdf https://link.springer.com/content/pdf/10.1186/s12199-021-009... https://www.ucsfbenioffchildrens.org/conditions/obesity#:~:text=A%20child%20with%20one%20obese,80%20percent%20chance%20of%20obesity https://www.ucsfbenioffchildrens.org/conditions/obesity#:~:t....
