This study analyzed the dietary education status and needs of 283 Vietnamese marriage migrant women in Korea from February 3 to 28, 2025, focusing on dietary adaptation factors. Overall, 20.8% of participants engaged in education, primarily in the complete-assimilation and assimilation-separation categories. The internet was the main source of dietary information, utilized by 65.4% of respondents, while those in the integrated-separation and marginalized categories more frequently accessed support from multicultural family centers. The primary challenges in managing family dietary life included educating children about healthy eating habits and, for those in the assimilation-separation category, adjusting family meal preferences. The dietary education content experienced by participants included traditional Korean dietary practices, fermented foods, and Korean cooking practices. Reasons for non-participation were primarily childcare or household responsibilities (29.5%) and busy work schedules (27.7%). In terms of family dietary education needs, topics such as healthy eating and health, healthy eating for families, and food hygiene and safety management all received scores above 4.0. For children's dietary education needs, all topics also scored above 4.0, with the complete-assimilation group ranking highest for education on children's Korean dietary practices and culture, while the passive-adaptation group ranked lowest in both areas. The importance-satisfaction analysis (ISA) identified food hygiene and safety management, as well as Korean cooking practices, as areas needing maintenance, while understanding Korean culinary culture was highlighted as a priority for improvement. This finding indicates the necessity for tailored, practice-based, bilingual programs.

This study investigated nutrition quotient (NQ) scores of 283 Vietnamese marriage migrant women and their children in Korea and analyzed the influence of maternal dietary adaptation factors on children's dietary quality. The survey was conducted from February 3, 2025 to February 28, 2025. Based on the acculturation theory, mothers were classified into five dietary adaptation types: complete-assimilation, mixed assimilation-separation, integrated-separation, marginalization, and passive-adaptation. Among preschoolers, the complete-assimilation type had the highest total scores of balance (89.0) and practice (83.4), the lowest score of moderation (30.8), and the highest overall NQ-P score (77.8). Among preschool children, the passive-adaptation type showed the lowest total scores for all domains except moderation. In school-age children, the mixed assimilation-separation type had the highest total scores, while the passive-adaptation type had the lowest scores across all domains except moderation. Among mothers, the complete-assimilation type had the highest total scores in balance (88.0), moderation (66.1), and practice (89.6) domains with, the highest overall NQ-A score (82.1), while the passive-adaptation type had the lowest total scores in all domains except moderation. These results confirm that maternal dietary adaptation can affect children's dietary quality highlighting the importance of dietary education and support for mothers during this stage.
