Objectives: The objective of this study was to examine the effect of nursing intervention based on Nel Noddings care theory on self-management behavior and symptomatic improvement in school-age asthmatic children in China. Methods: In this study, a sample of 100 school-aged children suffering from asthma was chosen, and divided into two groups: observation group and control group. Both groups received routine nursing but the observation group was combined with nursing intervention based on Nel Noddings theory.Results:The total scores of social psychologies, daily life, disease medicine and self-management in the observation group before intervention were similar to those in the control group. The self-management scores of the observation group after intervention were higher than those of the control group. The improvement time of wheezing and cough in the observation group was shorter than that in the control group. The total number of complete compliance and partial compliance in the observation group was higher than that in the control group. Conclusion: The application of nursing intervention based on Nel Noddings care theory to the nursing of school-age asthmatic children can improve the self-management ability of children, promote the recovery of cough, wheezing and other symptoms, and is of great significance to improve the compliance and nursing effect of children, with high popularization and application value.
