I'd imagine it has more to do with independence than with hobbies. Educated women get jobs that pay well and can do whatever they please, they don't have to rely on a husband and stay at home. IIRC, it's strongly correlated to income (which of course is closely coupled to education), and I'm pretty sure that poor women do not have more children because they're bored or don't know what else to do.
