An oxidation will result in a net decrease in the number of CH bonds, or a net increase in the number of CO bonds or equivalent. All of these events affect the oxidation state of the carbon, and this ties back to the concept of oxidation that I originally learned in high school: keeping track of the gaining and losing of electrons.
