Association of dietary phytochemical index and mental health in women: A cross-sectional study
This 2019 study focused on the possible relationship between dietary phytochemical index (DPI) and symptoms of depression, anxiety and psychological distress among 488 Iranian women (aged 20-50). The DPI was estimated using the formula: (daily energy derived from phytochemical-rich foods (kJ)/total daily energy intake (kJ))×100. Questionnaires were used to assess diet (validated and reliable FFQ) and symptoms of depression, anxiety and psychological distress (validated depression, anxiety, stress scales). The study participants were recruited from health centres in the south of Tehran, and averaged 31·9 (sd 7·7) years in age. Signs of depression, anxiety and psychological stress were seen in 34·6, 40·6 and 42·4 % (respectively) of the studied population. Results showed women in the highest tertile of DPI had 78%, 67% and 70% lower risks in developing depression, anxiety and psychological stress, respectively, compared with those in the lowest tertile. Although this study showcases the significant association between DPI and mental health in Iranian women, prospective studies are required for further confirmation.
