Interior Doors Sticking in the Winter

We have several interior doors that only stick or won't completely close in the winter. We also get cracks in the drywall mud above the doors so I think something else is going on besides just humidity changes in the door and frame. This is a wood framed house with wood trusses and a metal standing seam old-fashioned roof. I remember hearing a DIY radio show discussing the issue but I can't remember the solution. I think it had something to do with the wooden trusses in the attic. Any information is appreciated.
