Does having kids make dads fat?

Matt Richtel rediscovered a study that I did with Truls Ostbye and colleagues at Duke nearly a decade ago that found that having children was associated with an increased risk of obesity for men in middle age (a 4% increase in chance of being obese per child for men, versus 7% per child for women; controlling for other factors). It is important to note that this is an association that was found as part of a project that was looking at obesity interventions targeted to at-risk mothers after childbirth, including considering hormonal explanations. An impact of children on obesity in dads would seem to be explained by social phenomena as opposed to a direct biological explanation (I think; there are likely indirect effects, like lack of sleep that could have biological impacts).

I personally can identify with the “garbage disposal” theory that Richtel lays out:

It’s in the middle of shoving the rest of the pasta shells into my mouth that I realize how far I’ve backslid. I play garbage pail at dinner (proudly, hate to waste that extra bite), and when I’m making a good-night snack for one of my kids, I usually make one more for myself. A few days ago, I considered eating a piece of mozzarella my daughter had dropped. Onto the pavement. At the zoo.
