This article doesn’t mention anything about the eating habits in these households. What about the health and weight status of the parents (I guess the mother in this case)? If they already had bad eating habits and wrong lifestyle choices in place, I don’t think it would make much of a difference if the mothers worked all the time or not. I agree with you that they should have done a study on the fathers as well, not just the mothers in order for this experiment to be more accurate. I see stay home moms who make horrible choices for them and their kids when it comes down to diet, nutrition and healthy lifestyles. With the moms gone most of the day (assuming the dads are not around as well), it might be providing the kids with the freedom to eat bad foods and of course the negative effect that has on their mental and psychological state as well.
