摘要：Background: Mother’s nutrition during lactation is a factor affecting the quality and quantity of their milk. The present study aimed to investigate the direct and indirect effects of macronutrients on the amount of their energy intake.Method: This cross-sectional study was conducted in Khorramabad, and the target population included lactating mothers with a lactation period of 12 months or less. Using the dietary record (DR) in three days, the participants’ nutritional status and food intake were assessed. For distinguishing the importance of variables based on their direct and indirect effects on energy, non-parametric path analysis was employed.Results: The median level of energy intake was 1719.60 calories. Carbohydrates and proteins had the strongest and weakest effects on energy intake, respectively; and the strongest indirect effect was observed in fiber, MUFA, and Isoleucine.Conclusion: Considering the path coefficients related to direct and indirect effects and the effect of each macronutrient on the amount of energy intake, lactating mothers should be informed with the help of intervention programs about the importance of having proper nutrition to receive adequate nutrients and energy.
