A number of states are moving to regulate social media use among children and teens.

New York State is the latest with a new law that would allow parents to block their children

from getting social media posts suggested by a platform's algorithm.

About one in five American adolescents report having anxiety and depression, and CDC data show

teenage girls are facing record levels of sadness and suicide risk.

It all comes amid a larger conversation about social media and smartphones.

Stephanie Sigh has more.

On a recent morning in Durango, Colorado, students file into Mountain Middle School.

But before entering, 14-year-old Julia Fernandez shuts off her cell phone and puts it into

her backpack.

So this school has a ban on cell phone use.

How is that going?

I personally agree with the cell phone ban.

We have a lot of people with anxiety and depression, but I feel like it gives

it a pause. A day without a cell phone, it's just a pause in that, because that's not the reason that we have these issues but it is a factor.

Mountain Middle School first enacted the policy in 2013 when Shane Voss

became head of the public charter school.

Where did cell phone use rank in your mind in importance?

I think it was really at the top.

You know, we really wanted to teach students to dedicate their full energy and be present.

And it started with the cell phones.

As it's coming home with you?
