Abstract

Objectives: The present study evaluated the association between plant-based diet index (PDI) and psychological symptoms, including depressive symptoms, stress, and anxiety among Iranian women diagnosed with migraine headaches.

Methods: A cross-sectional study was conducted on 262 patients with migraine (aged 20-50 years; body mass index, 18.5-30 kg/m²). Three versions of the PDI were calculated: overall PDI, healthy PDI (hPDI), and unhealthy PDI (uPDI) based on dietary data collected via a 168-item food frequency questionnaire (FFQ). Psychological symptoms, including depressive symptoms, anxiety, and stress, were assessed using the Depression, Anxiety, Stress Scale-21 (DASS-21) questionnaire.

Results: After adjustment for potential confounders, patients in the highest tertile of the PDI showed a lower risk of depressive symptoms [odds ratio (OR) = 0.41, 95% confidence interval (CI): 0.22, 0.77]. Furthermore, inverse associations were evident between the PDI score and the risk of stress (OR = 0.46, 95% CI: 0.24, 0.85).

Discussion: Higher adherence to a plant-based eating pattern is associated with a reduced risk of psychological symptoms. However, future longitudinal studies and clinical trials should replicate our observations and delineate the underlying mechanisms driving these associations.

期刊介绍： Nutritional Neuroscience is an international, interdisciplinary broad-based, online journal for reporting both basic and clinical research in the field of nutrition that relates to the central and peripheral nervous system. Studies may include the role of different components of normal diet (protein, carbohydrate, fat, moderate use of alcohol, etc.), dietary supplements (minerals, vitamins, hormones, herbs, etc.), and food additives (artificial flavours, colours, sweeteners, etc.) on neurochemistry, neurobiology, and behavioural biology of all vertebrate and invertebrate organisms. Ideally this journal will serve as a forum for neuroscientists, nutritionists, neurologists, psychiatrists, and those interested in preventive medicine.
