Abstract
Purpose
Post-partum depression (PPD) is a mood disorder that affects 20-40 per cent of women in their post-delivery period worldwide. The purpose of this paper is to compare dietary intakes of energy, macronutrients, cholesterol, saturated fatty acids (SFAs), mono-unsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), some micronutrients and antioxidants in PPD patients with healthy controls.
Design/methodology/approach
This case-control study was conducted on 163 women in postpartum period (81 PPD and 82 non-PPD) using Edinburgh questionnaire for the diagnosis of PPD. Dietary nutrients intake was assessed using 147-item semi-quantitative food frequency questionnaire (FFQ). Portion sizes of food items were converted to grams per day. Logistic regression models were used to estimate the association between tertiles of dietary intakes with the odds ratio (OR) of PPD.
Findings
According to the fully adjusted model, highest tertile compared to lowest tertile dietary intake of SFAs [OR = 0.01; 95 per cent confidence interval (CI) = 0.00, 0.01, p = 0.001], MUFAs (OR = 0.01; 95 per cent CI = 0.00, 0.02, p < 0.001), total fats (OR = 0.01; 95 per cent CI =0.00, 0.01, p < 0.001) and cholesterol (OR = 0.06 ; 95 per cent CI = 0.01, 0.08, p < 0.001), thiamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), riboflavin (OR = 0.10; 95 per cent CI = 0.02, 0.39, p < 0.001), pyridoxine (OR = 0.03; 95 per cent CI =0.01, 0.32, p < 0.001), folate (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), cobalamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001) , selenium (OR = 0.79 ; 95 per cent CI =1.36, 3.32, p < 0.001), iron (OR =0.68; 95 per cent CI = 0.24, 0.94, p < 0.001) and iodine (OR = 0.36; 95 per cent CI =1.10, 1.38, p < 0.001) had a protective effect on the incidence of PPD. Furthermore, higher intake of vitamin A and beta-cryptoxanthin can increase the incidence of PPD (OR =114.29; 95 per cent CI =17.85, 118.12, p < 0.001) and (OR = 4.85; 95 per cent CI = 1.49, 15.69, p = 0.015), respectively.
Originality/value
PPD may have destructive effects on the relationship between mother and infant. Results of previous studies demonstrated nutrients are required for the synthesis of neurotransmitters and have biochemical role in the nervous system.

Abstract
Purpose
This paper aims to introduce a novel structure for the physical internet (PI)–enabled sustainable supplier selection and inventory management problem under uncertain environments.
Design/methodology/approach
To address hybrid uncertainty both in the objective function and constraints, a novel interactive hybrid multi-objective optimization solution approach combining Me-based fuzzy possibilistic programming and interval programming approaches is tailored.
Findings
Various numerical experiments are introduced to validate the feasibility of the established model and the proposed solution method.
Originality/value
Due to its interconnectedness, the PI has the opportunity to support firms in addressing sustainability challenges and reducing initial impact. The sustainable supplier selection and inventory management have become critical operational challenges in PI-enabled supply chain problems. This is the first attempt on this issue, which uses the presented novel interactive possibilistic programming method.
