Ethnic differences were noted in nutritional habits at baseline, as indexed by the overall DASH adherence score (F(1,166) =3.82, p = 0.05). Ethnicity remained significantly associated with overall DASH adherence at 16 weeks (β = −0.39, t (138) =−3.29, p<0.002), with poorer post-treatment adherence in African Americans than whites.
