The correct answer seems most likely to be prevention.
Taking action to avoid disease, injury, and other negative health outcomes would be in the form of prevention. If you are trying to avoid these things one of the best ways to do that would be to focus on educating people on how to prevent getting to a stage where they have ended up with a disease or injury or some other negative health outcome. Prevention can be key in enabling people to live healthier and less risky lifestyles.
