After adjustment of the confounding variables, legume consumption had no significant association with depression (P = ۰.۷۲), anxiety (P = ۰.۱۷), and stress (P = ۰.۸۹). However, a significant association was found between moderate legume consumption and depression (OR: ۰.۵۲; ۹۵% CI: ۰.۳۰–۰.۹۰; P = ۰.۰۱).
