Sommaire de l'article

PURPOSE
This study examines whether adherence to the Mediterranean Diet (MD) measured by several dietary indexes was associated with incident depressive symptoms in a large French cohort.

METHODS
The study sample consisted of 3523 participants from the Supplémentation en Vitamines et Minéraux Antioxydants (SU.VI.MAX) cohort who had at least three dietary records at baseline during the first 2 years of follow-up (1994-1996), free of depression at the beginning of the study (1996-1997) and available Center for Epidemiologic Studies Depression Scale (CES-D) data at the end of follow-up (2007-2009). The rMED was computed. Incident depressive symptoms were defined by a CES-D score ≥17 for men and ≥23 for women in 2007-2009. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using multivariable logistic regression models. Several sensitivity analyses were performed.

RESULTS
In the present study, 172 incident cases of depressive symptoms were identified during the follow-up (mean = 12.6 years). After adjustment for a wide range of potential confounders, adherence to the rMED score (continuous variable) was significantly associated with incident depressive symptoms in men (OR 0.91; 95% CI 0.83-0.99; p = 0.03), but not in women. Use of the Literature-Based Adherence Score to the Mediterranean Diet (LAMD) and the classic MD score (MDS) provide similar findings.

CONCLUSIONS
In the current study, higher adherence to the Mediterranean Diet at midlife was associated with a lower risk of incident depressive symptoms, particularly in men, increasing scientific evidence for a beneficial role of Mediterranean Diet on health. Further investigations in particular among women are needed.
