The poor cooking methods of take-out foods and fast foods caused a large accumulation of unhealthy ingredients in the body, including fat, salt, and sugar ( 1, 5). In recent years, fast foods, take-out foods, and prepackaged foods have become increasingly popular, with a rapid increase in the consumption rate of them ( 1– 3), among which, the consumption rate of prepackaged foods in China has reached 59.8% ( 4). Future research should focus on better understanding the motivations of residents to use nutrition labeling and the opportunity to use nutrition labeling in real-life shopping settings. The KAP model is suitable for explaining residents' use of nutrition labeling in the region. It could be explained that nutrition knowledge was the prerequisite for label reading behavior, and attitude was the intermediary effect.Ĭonclusion: The nutrition knowledge and nutrition labeling knowledge of respondents hardly directly support the practice of nutrition labeling, but it can influence the use behavior by forming a positive attitude. Attitude played a greater role as an indirect effect between knowledge and behavior, while trust limits residents' practice of nutrition labeling and then affects their practice. Based on the KAP structural equation model (SEM), residents' nutrition knowledge will directly affect their attitude toward nutrition labeling. Univariate analysis showed that women had higher knowledge scores than men ( p < 0.05), and young people had higher scores than older adults ( p < 0.05), and the difference was significant. Most residents had a positive attitude toward nutrition labeling, but the awareness rate was only 32.7% and the utilization rate was 38.5%. The average score of community residents' nutrition knowledge was 7.48 ± 3.24, and the passing rate was 19.4%. Results: According to the principle of sample size estimation, a total of 636 individuals were investigated, with the ratio of male to female being 1:1.2. This study adopted the structural equation modeling approach to analyze a survey of Chinese individuals through the cognitive processing model, interrelated nutrition knowledge, nutrition label knowledge, attitude, and practice. Methods: We carried out a cross-sectional study from May 2022 to July 2022 in the “Community Health Service Center”, and each “Community Service Station” in Yinchuan use a self-designed questionnaire and convenience sampling to evaluate resident nutrition labeling KAP status. Our study used a structural equation model based on the KAP theory to analyze the interaction mechanisms among knowledge, attitude, and practice and aimed to evaluate the relationships among nutrition knowledge, attitude, and practice of residents, which can provide the basis of policy formulation for nutrition education and behavior intervention. However, the public awareness of this measure is not clear. The promotion of nutrition labeling in the community can effectively help residents to choose healthy foods, which plays an important role in the prevention of chronic diseases. Objective: Unhealthy foods were a major contributor to the occurrence of chronic non-communicable diseases. 2Ningxia Key Laboratory of Environmental Factors and Chronic Disease Control, Yinchuan, Ningxia, China.1School of Public Health and Management, Ningxia Medical University, Yinchuan, Ningxia, China.
