(1) Background: Improving nutrition literacy is crucial for maintaining a healthier state of the elderly to achieve healthy ageing. Therefore, it is necessary to develop a Nutrition Literacy Questionnaire for the Chinese Elderly (NLQ-E). (2) Methods: an NLQ-E was developed according to the core components of nutrition literacy for the elderly. Internal consistency, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to validate the reliability and validity of the NLQ-E. A cross-sectional study of 1490 elderly people was used to analyze the application of the NLQ-E. (3) Results: The NLQ-E was constructed with 3 domains (knowledge and understanding, healthy lifestyle and dietary behavior and skill), with a total of 25 questions. The overall NLQ-E had acceptable reliability and validity (Cronbach's α = 0.678, χ/DF = 4.750, RMSEA = 0.045, PCFI = 0.776 and PNFI = 0.759). The average nutrition literacy score of the subjects in this cross-sectional study was 65.95 (65.95 ± 10.93). The OR between the nutrition literacy score and multimorbidity was 0.965 (95% CI: 0.954, 0.976); (4) Conclusions: We developed and validated the NLQ-E and found that the nutrition literacy level of the Chinese elderly was generally low. This study is of great value to improve the nutrition literacy of the elderly and effectively prevent nutrition-related chronic diseases and multimorbidity.
（1）背景：提高营养素养对于老年人保持更健康的状态以实现健康老龄化至关重要。因此，有必要为中国老年人开发一个营养素养问卷（NLQ-E）。（2）方法：根据老年人营养素养的核心要素，制定 NLQ-E。采用内部一致性、探索性因子分析（EFA）和验证性因子分析（CFA）对 NLQ-E 的信度和效度进行验证。采用横断面研究对 1490 名老年人进行分析。（3）结果：NLQ-E 由 3 个领域（知识与理解、健康生活方式和饮食行为与技能）组成，共 25 个问题。NLQ-E 的总体信度和效度可接受（Cronbach's α = 0.678，χ/DF = 4.750，RMSEA = 0.045，PCFI = 0.776，PNFI = 0.759）。该横断面研究中，受试者的平均营养素养得分为 65.95（65.95 ± 10.93）。营养素养得分与多种慢性病的比值比（OR）为 0.965（95%CI：0.954，0.976）；（4）结论：我们开发并验证了 NLQ-E，发现中国老年人的营养素养水平普遍较低。本研究对于提高老年人的营养素养，有效预防营养相关慢性病和多种慢性病具有重要价值。
