Yes, unless they were included on a previous backup or an icloud backup.
You can check which itunes backups you have by going to..
Windows - Edit menu > Preferences > Devices tab
Mac - iTunes menu > Preferences > Devices tab.
Or you can goto settings > icloud > storage and backup > manage storage and then click on your phone to see when the latest backup was done.
Hope this helps.
