Exploration of the association between dietary fiber intake and depressive symptoms in adults

Dietary fibre intake and depression in adults

This 2018 cross-sectional study assessed 16,807 adults (aged 20 years and over) on dietary consumption (obtained through two 24-hr dietary recall interviews) and depressive symptoms (using the Patient Health Questionnaire) with the aim of exploring the association between dietary fibre intake and the risk of developing depression. Results showed that dietary intakes of total, cereal, vegetable, and fruit fibre were inversely associated with depressive symptoms in unadjusted model and multivariate-adjusted model 1. Also, in multivariate-adjusted model 2, when the highest quintile was compared to the lowest quintile with respect to total, cereal, vegetable, and fruit fibre intakes, the odds ratios of depressive symptoms were 0.59, 0.90, 0.58 and 0.64, respectively. While dose-responses analyses revealed the non-linear association between total fibre consumption and depression risk, the relationships with cereal, vegetable and fruit fibre intake were found to be linear. While further larger prospective studies are required to confirm these findings, Xu et al. (2018) and their results suggest inverse associations between consumption of total fibre, vegetable fibre, and fruit fibre with depressive symptoms.
