Objective: To investigate the relationship between coarse grains intake and the score of knowledge, attitudes and practices (KAP), and to detect the possible related factors for the KAP scores. Method: The information of the residents was obtained from trained investigators using face-to-face interviews, including residents' general characteristics, KAP related coarse grains. The data were entered into EpiData version 3.1 and analyzed by IBM SPSS Statistics 25.0. Result: 374 residents from 4 communities in Zhengzhou participated the study, in which 71.1%, 87.2%, 13.9% and 76.0% of the interviewees' total KAP score, knowledge score, attitude score and practices score were unqualified, respectively. Significant positive associations were found between total KAP score and whole grain intake, tuber intake and beans and their products intake (r_s = 0.402, r_s = 0.228, r_s = 0.216, respectively; P < 0.01). Multivariate logistic regression analysis showed that he KAP scores of coarse grain were significantly related to the age, education level and occupation (all P <0.05). Conclusion: The residents have a low level of nutritional knowledge and consumption practice. According to the relationship between coarse grain intake level and KAP scores, in view of the current nutritional status of the residents，the relevant departments should mainly guide the young residents on the nutrition of coarse grains, especially tubers，and in view of the long-term development for national health, they could add the knowledge of coarse grain nutrition to the curriculum of primary and secondary schools.
