[Effect of children's oral health cognition and behavior on oral health status].

PURPOSE: To investigate the current status of oral health cognition behavior and oral health status of children, and to provide countermeasures for the prevention and treatment of oral diseases in children. METHODS: A total of 387 primary school students in the urban area of Shanghai from December 2018 to February 2019 were surveyed using Children's Oral Health Questionnaire and child oral health impact profile（COHIP）. SPSS 24.0 software package was used to conduct statistical analysis of the results through descriptive, univariate and multivariate analysis. RESULTS: The cognition of oral health of children aged 6-9 years old in Shanghai urban area was generally good, but their oral health behavior was average. The caries rate of 387 children reached 57.4%, and the oral health status was not good. Correlation analysis and regression analysis showed that children's oral health behavior was positively correlated with oral health cognition（r=0.260，P<0.05）, and negatively correlated with positive and negative effects of oral health status（r=-0.333，-0.181，P<0.05）, while children's oral health cognition had no significant effect on their oral health status（P>0.05）. CONCLUSIONS: The better the oral health behavior habits of children, the greater the positive impact on oral health status; the development of oral health education for children requires more attention to the cultivation of oral health behavior patterns.
