Abstract: Objective To analyze the influencing factors for children's non-organic anorexia, so as to provide reference for improving parents′ cognition and reducing the incidence of children's non-organic anorexia. Methods A total of 122 children aged 1 - 6 yearsfromSeptember 2019 to December 2020 were included in the study, of whom 61 children with non-organic anorexia were selected as theanorexia group and 61 children with normal physical examination were selected as the control group. A survey was completed by the families of the children by questionnaire. Univariate analysis was used to collect data, and multivariate Logistic analysis was used for the determinants additionally. Results Non-organic anorexia was influenced by factors such as temperament type (χ²=34.444), feeding patterns(χ²=7.935), age of adding supplementary food(t=7.201),eating duration (χ²=5.638), chase or tease during feeding (χ²=4.753), selective or picky eating (χ²=4.848), snack (χ²=4.560), hemoglobin level (t=4.282), trace elements, feeding caregivers(χ²=8.531), caregiver's education level(χ²=8.531),education mode(χ²=5.025), forced feeding(χ²=8.505) and parenting knowledge (χ²=5.026) (P<0.05). Multivariate Logistic regression analysis showed that the later time for adding complementary food (OR=6.922, 95%CI: 2.757 - 17.379,P＜0.001) and feeding duration≥40min (OR=4.582, 95%CI: 1.041 - 20.161, P=0.044) were independent risk factors for non-organic anorexia. Conclusions Non-organic anorexia in children is influenced by many factors. Timely addition of complementary foods, rational diet, creation of a good eating environment for children and popularization of scientific feeding knowledge can reduce the prevalence of non-organic anorexia nervosa in children.
