A recent study found that men who more strongly endorse traditional masculine norms experience higher stress and are less likely to seek mental health help, emphasizing the need to address gender-specific barriers and promote positive masculine traits.

Similar words, both would work. Look them up if you’re interested. Exponent connotes more of a “believer” to me, whereas the proponent is an advocate.
TIL. Thanks!
