A longitudinal analysis of diet quality scores and the risk of incident depression in the SUN project
Background: Some studies have pointed out that several dietary patterns could be associated with a reduced risk of depression among adults. This association seems to be consistent across countries, cultures and populations. The objective of the study was to compare and to establish the type of rel...

| description | Background: Some studies have pointed out that several dietary patterns could be associated with a reduced risk
of depression among adults. This association seems to be consistent across countries, cultures and populations. The
objective of the study was to compare and to establish the type of relationship between three diet quality scores
and depression in the SUN (Seguimiento Universidad de Navarra) Cohort study.
Methods: We performed a dynamic cohort study based on Spanish university graduates free of depression at baseline.
Dietary intake was repeatedly assessed at baseline and after 10 years of follow-up with a validated semi-quantitative foodfrequency
questionnaire. Three previously described diet quality scores: Mediterranean Diet Score (MDS), Pro-vegetarian
Dietary Pattern (PDP) and Alternative Healthy Eating Index-2010 (AHEI-2010) were built. Participants were classified as having
depression if they reported a new clinical diagnosis of depression by a physician or initiated the use of an antidepressant
drug during follow-up. Time-dependent Cox regression models with cumulative averages of diet and restricted cubic splines
were used to estimate hazard ratios of depression according to quintiles of adherence to the MDS, PDP and AHEI-2010.
Results: One thousand and fifty one incident cases of depression were observed among 15,093 participants from the
SUN Cohort after a median follow-up of 8.5 years. Inverse and significant associations were observed between the three
diet quality scores and depression risk. The hazard ratios and 95 % confidence intervals for extreme quintiles (fifth versus
first) of updated adherence to MDS, PDP and AHEI-2010 were 0.84 (0.69–1.02), 0.74 (0.61–0.89) and 0.60 (0.49–0.72),
respectively. The dose–response analyses showed non-linear associations, suggesting that suboptimal adherence
to these dietary patterns may partially be responsible for increased depression risk.
Conclusions: Better adherence to the MDS, PDP and AHEI-2010 was associated with a reduced risk of depression
among Spanish adults. However, our data suggested a threshold effect so that although the risk of depression was
reduced when comparing moderate versus lower adherence, there was not much extra benefit for the
comparison between moderate and high or very high adherence. |
