Abstract：Objective To explore the prevalence of behavioral problems among preschoolers and discuss the related factors which lead to psychological and behavioral problems. Methods With cluster random sampling, the questionnaires, including Achenbach's child behavior checklist (CBCL), behavior style questionnaire (BSQ) and other self-made questionnaire, were used to analyze the behavioral problems and related factors of 1 824 children who aged between 4 and 6 years from 10 kindergartens of Yangpu District in Shanghai. Results The prevalence rate of behavioral problems in the study population was 26.42%, with the rates of 30.39% and 22.11% in the boys and girls, respectively. There was statistically significant difference between them. The first three behavioral problems in the boys were sexual problems, schizoidia, and discipline violation, while those in the girls were obesity, sexual problems, and hyperactivity. High maternal age, the only child, an outgoing father, harmonious family relationship, and easy characteristics type were found to be protective factors in the multivariate Logistic regression. On the other hand, boys, with medical history, chronic somatic disease, traumatic experiences, eating snacks twice or three times per day, a drinking mother, a mother with high school and above diploma, and hard characteristics type were found to be risk factors. Conclusion The study suggests that the incidence of preschool children's behavioral and emotional problems is high, and moreover, the major problem is sexual problems. Preschool children are easily influenced by themselves and their family related factors. The tertiary prevention work of health education and mental health on children with mental health problems should be strengthened.
