Abstract

Aims: This study was conducted to determine nutritional literacy's effect on pregnant women’s psychological well-being.
Methods: This descriptive cross-sectional study was conducted between December 2023 and June 2024 with 302 pregnant women. R programing language 4.1.3, G*Power 3.1, and SPSS-22 were used in the study.
Results: In this study, the model established by hierarchical regression analysis was significant and usable (F(2,299)=22,019, p=0.001). Religious health fatalism and food literacy levels explain 12.8% (R2=0.128) of the total variance in psychological well being. In the regression model, when the t-test results regarding the significance of the regression coefficient were examined, it was determined that the increase in the level of religious health fatalism (t=5.583, p<0.001) and the decrease in the level of food literacy (t=-4.810, p<0.001) caused a statistical increase in the level of "psychological well-being". In the machine-learning prediction, health fatalism was determined as the most important variable for predicting psychological well-being.
Conclusion: In this study, health fatalism and nutrition literacy affected psychological well-being. Detailed studies on psychological well-being in pregnant women are recommended.
