Abstract

Highlights: More than 29% of Iranian adolescent girls have mild to severe depressive symptoms. Factor analysis was used to identify three major dietary patterns: Healthy, Traditional and Western patterns. Adherence to a healthy dietary pattern is associated with a lower probability of having depressive symptoms among Iranian adolescent girls. There were no significant associations between the Traditional and Western dietary patterns and depression symptoms. Abstract: There is growing interest on the impact of diet on depressive disorders. However, there are limited data on the association between dietary patterns and depression symptoms among Iranian adolescents. The aim of this study was to evaluate the association between dietary patterns and depression score among Iranian adolescent girls. Data were obtained from 750 adolescent girls, who were recruited from several schools using a random cluster sampling. Dietary data were collected using a valid and reliable food frequency questionnaire (FFQ). Beck's depression inventory (BDI-II) was used to assess depression severity score. The prevalence of girls diagnosed with depression was 29.1%. Three major dietary patterns were identified in the study based on factor analysis: "Healthy", "Traditional" and "Western". The multivariate-adjusted odds ratio of having depressive symptoms was 0.55 (95% confidence intervals, 0.34–0.89) for the highest versus lowest quartile of the healthy dietary pattern score. However, there were no significant associations between the Traditional and Western dietary patterns and depression symptoms. Our results indicate that adherence to a Healthy dietary pattern characterized by high intakes of fruits, vegetables, fish and dairy products is associated with a lower probability of having depressive symptoms among Iranian adolescent girls.
