  1. -: The variable was not included in the multivariable analysis. Significant predictors (P < 0.1) of breast milk macronurtrients composition in bivariate analyses were included as cofounding factors in the multivariable linear regression model. Lactation period, educational level and occupation were included in the multivariable linear regression model of associations between dietary patterns and protein concentration. Lactation period were included in the multivariable linear regression model of associations between dietary patterns and fat concentration. Lactation period and parity were included in the multivariable linear regression model of associations between dietary patterns and lactose concentration. Lactation period and family economic status were included in the multivariable linear regression model of associations between dietary patterns and total dry matter and energy concentration
