Table 4 Mediation analysis for the relationship between dietary patterns and depression

dietary patterns	Model	1 p _value	2 p _value	3 p _value	OR(95%CI)
Healthy dietary pattern	Folate	0.028	0.10	< 0.001	0.4 (0.25–0.66)
Healthy dietary pattern	Vitamin B12	0.028	0.17	< 0.001	0.995 (0.993–0.998)
Unhealthy dietary pattern	Folate	0.020	0.30	< 0.001	0.5 (0.35–0.72)
Unhealthy dietary pattern	Vitamin B12	0.020	0.60	< 0.001	0.995 (0.993–0.998)

Model 1: Logistic regression model for studying the relation between depression and quartiles of dietary patterns
Model 2: Logistic regression model for studying the relation between quartiles of healthy dietary pattern and depression with mediation variables
Model 3: Logistic regression relationship between mediation variables and depression
All of 3 models were adjusted for job, education, marital status, children number, smoking and hookah use, depression history, unemployment history in the past 5 year, tragic events in the past 6 months and the whole lifetime, energy intake, physical activity and dietary patterns
