Association of the Mediterranean Dietary Pattern With the Incidence of Depression

Diet mediterrania dapat mengurangi risiko depresi karena  diduga berhubungan dengan reaksi inflamasi, vaskuler dan metabolisme.

 

Peneliti dari Spanyol melakukan desain kohort terhadap >10.000 orang dewasa sehat sejak tahun 1999 sampai sekarang.

Setelah median follow-up selama 4,4 tahun ternyata mereka yang paling patuh mengikuti pola diet mediterrania mempunyai risiko lebih rendah untuk terjadinya depresi secara signifikan.

Bahan makanan yang paling berpengaruh adalah buah, kacang2an, rasio MUFA:SAFA, dan polong2an

 

Disimpulkan bahwa diet mediterrania mempunyai fungsi protektif terhadap depresi

Association of the Mediterranean Dietary Pattern With the Incidence of Depression-The Seguimiento Universidad de Navarra/University of Navarra Follow-up (SUN) Cohort. Almudena Sanchez-Villegas, Miguel Delgado-Rodriguez, Alvaro Alonso, et al.

 

Context  Adherence to the Mediterranean dietary pattern (MDP) is thought to reduce inflammatory, vascular, and metabolic processes that may be involved in the risk of clinical depression.

Objective  To assess the association between adherence to the MDP and the incidence of clinical depression.

Design  Prospective study that uses a validated 136-item food frequency questionnaire to assess adherence to the MDP. The MDP score positively weighted the consumption of vegetables, fruit and nuts, cereal, legumes, and fish; the monounsaturated- to saturated-fatty-acids ratio; and moderate alcohol consumption, whereas meat or meat products and whole-fat dairy were negatively weighted.

Setting  A dynamic cohort of university graduates (Seguimiento Universidad de Navarra/University of Navarra Follow-up [SUN] Project).

Participants  A total of 10 094 initially healthy Spanish participants from the SUN Project participated in the study. Recruitment began on December 21, 1999, and is ongoing.

Main Outcome Measure  Participants were classified as having incident depression if they were free of depression and antidepressant medication at baseline and reported a physician-made diagnosis of clinical depression and/or antidepressant medication use during follow-up.

Results  After a median follow-up of 4.4 years, 480 new cases of depression were identified. The multiple adjusted hazard ratios (95% confidence intervals) of depression for the 4 upper successive categories of adherence to the MDP (taking the category of lowest adherence as reference) were 0.74 (0.57-0.98), 0.66 (0.50-0.86), 0.49 (0.36-0.67), and 0.58 (0.44-0.77) (P for trend <.001). Inverse dose-response relationships were found for fruit and nuts, the monounsaturated- to saturated-fatty-acids ratio, and legumes.

Conclusions  Our results suggest a potential protective role of the MDP with regard to the prevention of depressive disorders; additional longitudinal studies and trials are needed to confirm these findings.
