We study influence of electron-electron interaction on statistics of Coulomb blockade peak spacings in disordered quantum dots. It is shown that the interaction combined with fluctuations of eigenfunctions of the Fermi sea enhances the peak spacing fluctuations, in accordance with recent experiments. In addition, account of the spin degrees of freedom leads to a pronounced odd-even structure for weak interaction (e(2)/epsilon much less than upsilon(F)); in the opposite case (e(2)/epsilon greater than or similar to upsilon(F)) this structure is washed out.
