Objective Adolescence is a critical period for development of depression, and understanding of behavioural risk factors is needed to support appropriate preventative strategies. We examine associations between adolescent diet quality and depressive symptoms, cross-sectionally and prospectively, in a large community cohort, adjusting for behavioural and psychosocial covariates. Design Prospective community-based cohort study (ROOTS). Setting Secondary schools in Cambridgeshire and Suffolk, UK. Subjects Study participants (n=603) who completed 4-day diet diaries at age 14 and reported depressive symptoms (Moods and Feelings Questionnaire (MFQ)) at ages 14 and 17. Results Diet data were processed to derive a Mediterranean Diet Score (MDS) and daily servings of fruits and vegetables, and fish. At age 14, a negative association between fruit and vegetable intake and MFQ score was seen in the unadjusted cross-sectional regression model (β= -0.40 (95%CI -0.71;-0.10)), but adjustment for behavioural covariates, including smoking and alcohol consumption, attenuated this association. Fish intake and MDS were not cross-sectionally associated with MFQ score. No prospective associations were found between MDS, fruit and vegetable intake or fish intake and later MFQ score. Conclusions Diet quality was not associated with depressive symptoms in mid-adolescence. Previously reported associations in this age range may be due to confounding. Further longitudinal studies are needed which investigate associations between adolescent diet and depression across different time frames and populations, ensuring appropriate adjustment for covariates.
