Nutrition literacy in Vietnamese pregnant women: a cross-sectional study.

Inadequate nutrition intake during pregnancy elevates the risk of adverse health outcomes during pregnancy, with potential long-term repercussions for both mother and child, extending to subsequent generations. Current initiatives to improve individual dietary habits emphasize promoting nutrition literacy (NL), which encompasses the ability to access, comprehend, and use basic nutrition information and services necessary for making appropriate nutrition decisions. However, there were limited data on the NL of pregnant women in Vietnam. Therefore, this study aims to explore the NL levels of Vietnamese pregnant women and examine the factors related to their NL. A total of 360 Vietnamese pregnant women participated in the study from May to September 2023. A validated questionnaire (Nutrition Literacy Assessment Instrument for Pregnant Women, NLAI-P), assessing the knowledge, behavior and skill, was applied. A general linear model with univariate linear regression analysis was conducted to identify predictor factors of NL. The findings revealed that 70.3% of participants had inadequate NL. Among the three dimensions, nutrition knowledge was particularly low, with no respondents achieving an adequate level and 94.7% scoring at an inadequate level. High household monthly income, age, normal prepregnancy weight and indoor work were statistically associated with higher NL scores. This study highlights the limited NL among Vietnamese pregnant women. Increasing NL is crucial for supporting their optimal healthy diet, enhancing the health of pregnant women and their offspring and future generations.
