ambiguity - are there two meaning?

Other studies, including in the United States, have shown this same pattern, with girls who begin developing earlier than their peers vulnerable to depression in adolescence.

Without context, are there two meaning? :

1. Girls are vulnerable to depression in adolescence.


2. Peers are vulnerable to depression in adolescence.

Put another way: if sentence is

There are girls who begin developing earlier than their peers vulnerable to depression in adolescence.

then is there ambiguity which group is vulnerable to depression in adolescence?
