You ask if this is more common in young women. I think that it is more common in young women, but I think that it is not necessarily connected to gender. Instead, I think that it is connected to power relations.
I think that learned helplessness is connected to having little or no power. In many cultures, this applies to women. However, it can also apply to racial or ethnic minorities and to people who do not have very much money.
I believe that people who have little power get used to acting in helpless ways. In some cases, it becomes pathological.
