Abstract
Background
There are over 350 million people living in the world who experience the symptoms of depression. The World Health
Organisation estimates that depression will become the leading cause of disability-adjusted life years by 2030. Emerging
evidence in nutritional psychiatry suggests that dietary intake is a potentially important risk factor for depression. There
have been several meta-analyses and systematic reviews on the role of dietary patterns in depression, with conflicting
results. This study aimed to synthesise and provide a weighting of the current evidence across all such studies.
Methods
Two independent researchers: searched CINAHL, MEDLINE, Proquest, PsycINFO, and Scopus for meta-analyses and
systematic reviews on ‘dietary patterns’ and ‘depression’, selected 16 relevant publications, summarising 213 original studies, assessed the methodological quality of studies using the AMSTAR
Preliminary findings
Of the 16 included publications (10 meta-analyses & 6 systematic reviews), evidence was found across high-quality studies for healthy dietary patterns association with decreased risk of depression, in particular, Mediterranean dietary patterns. Evidence was also found for the association between unhealthy dietary patterns and the increased risk of depression. Analysis is ongoing to assess the weight of the evidence for each of the dietary pattern outcomes.
