BackgroundAffective disorders, especially depressive symptoms, bring such a burden to mortality and morbidity that they are associated with physical and psychological health and quality of life. Nuts, a foodstuff rich in multiple micronutrients, macronutrients, and other useful components, were considered to be a protector against depressive symptoms. Here, we conducted an analysis to examine the relationship between nut consumption and depressive symptoms. @@@ MethodsThe study performed a cross-sectional study to examine whether nut consumption is related to depressive symptoms among 13,626 inhabitants in Tianjin. Nut consumption was assessed using a validated food frequency questionnaire and depressive symptoms was assessed using the Chinese version of 20-item Self-rating Depression Scale (SDS) with four cutoffs (40, 45, 48, and 50) to indicate elevated depressive symptoms. @@@ ResultsThe prevalence of depressive symptoms was 38.7, 19.1, 11.4, and 7.3% for SDS 40, 45, 48, and 50, respectively. After adjustments for potential confounding factors, the odds ratios (95% confidence interval) of having elevated depressive symptoms with SDS 40 by increasing frequency of nut consumption were 1.00 for <once per week (reference), 0.82 (0.75, 0.90) for 1-3 times per week, and 0.82 (0.73, 0.92) for 4 times per week. Similar relations were observed with the use of other cutoffs as a definition of depressive symptoms. @@@ ConclusionThe present study is the first to find that nut consumption is independently associated with depressive symptoms. It is suggested that nut consumption may be beneficial to the prevention of depressive symptoms.
