Appropriate nutrient intake is essential for maintaining health and resisting disease. The current study investigated the association between household income quintile and nutrient intake using data from KNHANES 2019. A total of 5088 South Korean adults were analyzed. The estimated average requirement cut-point method, extended to handle participants with intakes higher than the tolerable upper level, was utilized to determine the need for dietary modification. The suitability of overall vitamin, overall mineral, and individual nutrient intake was evaluated by logistic regression analysis. Subgroup analysis was performed on overall mineral intake suitability. None of the individual nutrients had an intake ratio of over 70%, with the ratio being under 30% for some nutrients. The intake of iron, phosphorus, vitamin B9, and vitamin C had a significant upward trend as household income rose. A subgroup analysis revealed sex differences in the trends of overall mineral intake. The results revealed that some nutrients are not consumed appropriately in the Korean population. Furthermore, they suggest that household income is significantly associated with the intake of overall minerals and several individual nutrients. These results suggest that nutritional assistance is required for certain vulnerable groups, and provide supplementary data for appropriate interventions or further research.
适当的营养摄入对于维持健康和抵抗疾病至关重要。本研究利用 2019 年韩国国民健康营养调查（KNHANES）的数据，调查了家庭收入五分位数与营养素摄入之间的关系。共分析了 5088 名韩国成年人。采用扩展到可处理摄入量高于可耐受上限的估计平均需求量切点法来确定饮食调整的需求。通过逻辑回归分析评估了整体维生素、整体矿物质和个别营养素摄入的适宜性。对整体矿物质摄入适宜性进行了亚组分析。没有一种营养素的摄入量比例超过 70%，有些营养素的摄入量比例低于 30%。随着家庭收入的增加，铁、磷、维生素 B9 和维生素 C 的摄入量呈显著上升趋势。亚组分析显示，整体矿物质摄入趋势在性别方面存在差异。结果表明，韩国人群中某些营养素的摄入并不合理。此外，这些结果表明家庭收入与整体矿物质和一些个别营养素的摄入显著相关。这些结果表明，某些弱势群体需要营养援助，并为适当的干预措施或进一步研究提供补充数据。
