Nutritional literacy (NL) has a critical influence on food choices. The objective of the present study was to examine the association of NL with nutrition label use.
A cross-sectional study was conducted in Bengbu, China. In total, 955 adults were interviewed using a questionnaire designed for the present study to collect information on demographics, lifestyle, nutrition label use, and NL. Binary logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) for nutrition label use and its predictive variables.
In total, 40.4% of the participants reported looking at nutrition label when purchasing prepackaged foods. NL was significantly positively associated with nutrition label use and specifically with checking nutrition facts table, purported nutrition benefits and purported health benefits. In terms of specific facets of NL, nutrition knowledge, applying skills, and critical skills were associated with nutrition label use. After stratification by monthly income and education, the association between NL and nutrition label use was discovered only in individuals with low monthly income. Additionally, nutrition knowledge was associated with nutrition label use only in adults with high education level, whereas applying skills were associated with nutrition label use only in those with low education level.
The use of nutrition label remains low among Chinese community residents, especially the purported nutritional benefits and purported health benefits. NL is positively associated with nutrition label use, especially with respect to functional and critical NL, with differences based on socioeconomic status. The findings highlight the need for NL interventions targeting individuals with different levels of education and income to encourage use of nutrition label in China.
营养素养对食物选择具有关键影响。本研究的目的是探讨营养素养与营养标签使用之间的关联。
在中国蚌埠进行了一项横断面研究。总共对955名成年人进行了访谈，使用为本研究设计的问卷收集有关人口统计学、生活方式、营养标签使用和营养素养的信息。采用二元逻辑回归模型计算营养标签使用及其预测变量的比值比（OR）和95%置信区间（CI）。
总共40.4%的参与者报告在购买预包装食品时会查看营养标签。营养素养与营养标签使用显著正相关，特别是与查看营养成分表、声称的营养益处和声称的健康益处相关。就营养素养的具体方面而言，营养知识、应用技能和批判性技能与营养标签使用相关。按月收入和教育程度分层后，仅在月收入低的个体中发现营养素养与营养标签使用之间存在关联。此外，营养知识仅在高学历成年人中与营养标签使用相关，而应用技能仅在低学历人群中与营养标签使用相关。
中国社区居民中营养标签的使用率仍然较低，尤其是声称的营养益处和声称的健康益处方面。营养素养与营养标签使用呈正相关，特别是在功能性和批判性营养素养方面，且因社会经济地位存在差异。研究结果凸显了针对不同教育和收入水平的个体进行营养素养干预的必要性，以鼓励在中国使用营养标签。
