Yep.  According to medical life-expectancy statistics (not to mention quality-of-life), they'd actually be much better off if the dad were an alcoholic bum like a high percentage of First Nations parents but the kids weren't fat.  The years taken off by PTSD and substance addiction are dwarfed by the years taken off by being a landwhale and having T2 diabetes when you're still a child.  To the point that fat kids are why the US national life expectancy will decrease.
