What back problems do you experience? I can try to give you some advice! :)

I was diagnosed at the age of 28 purely because someone went into the back of my car resulting in me having to see an orthopaedic consultant because of severe back pain. He turned round and said "oh this injury really isn't going to help your scoliosis" er what? I'd had back pain ever since I could remember but no one ever pointed out until then that actually I'm shorter by an inch on left side due to the severe curvature of my spine. I'm now waiting for major surgery to fuse half of my back.

I was diagnosed as a child 30+ years ago and my spine was 'fused' but the best advice I can give to you is to concentrate on strengthening your core muscles as much as you can now, you'll need them to help keep your spine straight in the future. If you lose those muscles, you'll suffer with pain later on.
