Abstract：
Dietary behavior is a pivotal modifiable determinant in reducing the occurrence of obesity/overweight and chronic non-communicable diseases. Improving the dietary behavior of rural residents in China is imminent due to the poor performance of their dietary behavior. Nutrition knowledge and health literacy are considered as elements that are linked intimately to healthy dietary behaviors but lack research in the Chinese setting.
The study is designed to explore the relationship between nutritional knowledge, health literacy and dietary behaviors and to analyze the performance under different demographic characteristics.
A face-to-face survey of 400 rural residents on their nutrition knowledge, functional health literacy and dietary intake of five food categories consisting of 32 items was conducted based on a validated questionnaire. Descriptive analysis, difference test including ANOVA, t-test and non-parametric test, and multivariate linear regression were used for data analysis.
The results indicate that declarative nutrition knowledge, individuals\' information application capacity, and dietary behaviors, especially the intake of fruits, dairy and beans, and vegetable are not ideal and requires improvement. Male, elder, low-income, unmarried, and low-education populations performed significantly worse and were the high-risk group. Procedural nutrition knowledge, information access capacity, information understanding capacity, and information application capacity have remarkable effects on better dietary behavior.
This study provides evidence-based guidance for prioritizing information and populations for healthy dietary interventions.

摘要：
■饮食行为是减少肥胖/超重和慢性非传染性疾病发生的关键可改变的决定因素。由于我国农村居民的饮食行为表现不佳,改善其饮食行为迫在眉睫。营养知识和健康素养被认为是与健康饮食行为密切相关的要素，但在中国环境中缺乏研究。
■该研究旨在探索营养知识之间的关系，健康素养和饮食行为,并分析不同人口学特征下的表现。
■对400名农村居民的营养知识进行面对面调查，基于经过验证的问卷，对包括32项的5种食物类别进行了功能健康素养和饮食摄入。描述性分析,包括方差分析在内的差异检验，t检验和非参数检验，并采用多元线性回归进行数据分析。
■结果表明，陈述性营养知识，个人信息应用能力，和饮食行为，尤其是水果的摄入，奶制品和豆类,蔬菜并不理想，需要改进。男性,长者,低收入,未婚,低教育人群的表现明显更差,是高危人群.程序性营养知识，信息访问能力，信息理解能力，和信息应用能力对更好的饮食行为有显著影响。
■本研究为确定健康饮食干预的信息和人群的优先次序提供了循证指导。
