Not specifically about weight and body image issues, but Kaitlin Hopkins did a TED talk a few years ago about addressing mental health in performing arts majors, and students in general.

Knowing that this is directly addressed as part of the Texas State program, we specifically asked other programs how they handle and address mental health during our final visits before selecting a program back in 2017. It was not necessarily a deciding factor, but I think it is an important question to ask if for no other reason than to let all performing arts programs know this is something parents and students care about, so these programs should think about it, too.
