Determinants of adherence to the Mediterranean diet among adults in Mediterranean countries: a systematic literature review.

ABSTRACT:

Objective

This study aims to provide an overview of evidence on factors affecting Mediterranean diet (MD) adherence across socio-ecological levels (individual, interpersonal and environmental) in Mediterranean countries, which can be target points for future interventions to promote MD adherence.

Design

A systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines and registered in the Prospero database (CRD42020189337). Literature was searched in PubMed, Web of Science and PsycINFO.

Setting

The MD is one of the healthiest dietary patterns, reducing risk of chronic disease while promoting better health outcomes. However, adherence to the MD remains challenging, even in Mediterranean countries.
