We consider weighted anchored and ANOVA spaces of functions with first order mixed derivatives bounded in Lp. Recently, Hefter, Ritter and Wasilkowski established conditions on the weights in the cases p = 1 and p = ∞ which ensure equivalence of the corresponding norms uniformly in the dimension or only polynomially dependent on the dimension. We extend these results to the whole range of p ∈ [1, ∞]. It is shown how this can be achieved via interpolation. MSC: 65D30,65Y20,41A63,41A55
