Food choices that shape human diets and health are influenced by various socio-economic factors. Vietnam struggles to meet many nutrition targets where links between food choice and diet have not been widely explored. This study assesses the food choice motives, based on a 28-item food choice questionnaire (FCQ), and the diet quality of 603 adults in three sites (urban, peri-urban, and rural) in northern Vietnam. We assess diet quality using the Diet Quality Index-Vietnam (DQI-V) which consists of variety, adequacy, moderation, and balance components. Using factor analysis, we grouped FCQ items into five factors: health focus, sensory appeal, mood ethics, convenience, and familiarity. The structural equation modeling indicates that food choice motives significantly impact the DQI-V and its components but in different directions. The results show that sensory appeal has a positive association with the overall DQI-V score, while having a negative impact on the variety component. Findings present a potential trade-off issue for interventions and policies related to food products. Nutrition knowledge is positively associated with all elements of diet quality across all three study sites. Vietnamese agrobiodiversity could be better utilized to increase dietary diversity. Differentiated policies are necessary to address the poor dietary diversity and adequacy in northern Vietnam.
塑造人类饮食和健康的食物选择受到多种社会经济因素的影响。越南在实现许多营养目标方面面临困难，食物选择与饮食之间的联系尚未得到广泛探讨。本研究基于一份包含28个项目的食物选择问卷（FCQ）评估了越南北部三个地区（城市、城郊和农村）603名成年人的食物选择动机和饮食质量。我们使用越南饮食质量指数（DQI-V）评估饮食质量，该指数由多样性、充足性、适度性和平衡性组成。通过因子分析，我们将FCQ项目分为五个因子：健康关注、感官吸引力、情绪伦理、便利性和熟悉度。结构方程模型表明，食物选择动机对DQI-V及其组成部分有显著影响，但方向不同。结果表明，感官吸引力与DQI-V总分呈正相关，而对多样性部分有负面影响。研究结果为与食品相关的干预措施和政策提出了一个潜在的权衡问题。营养知识与所有三个研究地点的饮食质量的所有要素均呈正相关。越南的农业生物多样性可以得到更好的利用，以增加饮食多样性。需要制定差异化政策来解决越南北部饮食多样性和充足性差的问题。
