Minimal Supersymmetric Higgs Boson Decay Rate in O(\alpha_s^2) Perturbative QCD

A short presentation of the results of the analytical evaluation of the O(\alpha_s^2) QCD contributions in the fermionic decay rates of the neutral CP-odd minimal supersymmetric Higgs particle is made. The corrections due to the nonvanishing quark masses are included. The results are presented both in terms of running and pole quark masses.
