It is shown that within the L-p-Brunn-Minkowski theory that Aleksandrov's integral curvature has a natural L-p extension, for all real p. This raises the question of finding necessary and sufficient conditions on a given measure in order for it to be the L-p-integral curvature of a convex body. This problem is solved for positive p and is answered for negative p provided the given measure is even.
