Creation protection is generally used when a page is constantly created and deleted over and over. If this isn't true for your categories and they are still unwanted, you should look into developing a clear policy in terms of the categories used on the wiki instead of protecting pages. It sounds to me that you have more of a routine maintenance issue (involving deleting pages) than mass repetitive vandalism.

If you meant how to protect a page from being created, delete the page, copy the name of the page and replace it with the current page name in the URL then add add  to the end of the URL to bring up the protect options. For example, delete Category:Divorced and then go here. I can't explain that any better as it's as straightforward as possible.

If you are still confused, please be specific about what you need help with.
