Is it just the young men whose mental health is declining? I'd go a generation earlier and see how things start to get pretty bad. A lot of kids these days don't hang out in person, they are hanging out virtually while laying down in their beds or in comfortable chairs in front of their consoles or computers playing video games online. This is quite unealthy way to grow up. A lot of teenagers, male or female are also undetachable from their cellphones and social media too. This is also a very unhealthy way to grow up.
