How to connect a user to their additional profile data

Here’s the problem:

My client has added an extra profile field (field_id = 72) asking whether the client would like to receive the monthly newsletter. I suppose it’s saved in cscart_profile_fields_data but how will I link it to a user?

So basically what I need is a query that shows me all the users that want to receive the newsletter and those who don’t.

user1 Y

user2 Y

user3 N

user4 Y
