Still does tend to come from

仍然是中上阶层占大多数
the middle-upper classes, though not exclusively.

但也不绝对
You certainly see people from poor families

你可以看到出身贫寒的人
who present with anorexia nervosa.

患有厌食症
I assume because of the link to economic state,

由此我认为经济状况与此相关
tends still to be Caucasian in this country,

美国白种人是患病主流人群
but again, not exclusively,

但也要强调并非只有白种人
all racial and ethic groups can get this.

所有人种民族都有可能得这种病
The folks who develop anorexia nervosa: are they sick?

得了神经性厌食的他们真的是病了吗
Do they look strange or peculiar prior to illness onset?

患病期间病人会行为异常或者反复发病吗
Probably not much as best we know,

就我们目前所知的情况真不多
it's very hard to know for sure, but probably not much.

要确证这些很难而且所知也甚少
