Antisocial personality disorder and related factors of adolescents in multi-ethnic areas of China: A cross-sectional study

Background: Antisocial personality disorder (ASPD) has a high incidence and does serious harm to society and families. Although it has received widespread attention, there is no research on the relationship between ASPD and ethnic groups. Therefore, our goal is to study the prevalence, potential risk factors and ethnic correlation of ASPD among adolescents in multi-ethnic areas of China. Methods: We collected a sample of 2571 adolescents in China using a cross-sectional study. SPSS22.0 software was used with chi-square test for univariate analysis, logistics regression for multivariate regression analysis, to explore the distribution of ASPD and the relationship between social demographic factors. Results: The positive rate of ASPD screening among adolescents in multi-ethnic areas in China is 24.2% (95%CI:22.5~25.8). Univariate chi-square test showed that gender, age, educational background, nationality, subjective family economic situation, single-child family, father's education level and mother's education level were related to the positive rate of ASPD screening, and the difference was statistically significant. Further logistics regression analysis showed that male (OR=3.541,95%CI: 2.915-4.301), Lisu nationality (OR=1.750,95%CI: 1.259-2.433) and single-child family (OR=,95%CI: 1.028-1.776) were independent risk factors for ASPD. Age ≥ 19 (OR=0.394,95%CI：0.219~0.712) and educational background of senior high school (OR=0.451,95%CI：0.311~1.106) are protective factors of ASPD. Conclusions: High positive rate of ASPD screening among adolescents in multi-ethnic areas of China. Gender, age, educational background, nationality, subjective family economic situation, single-child family, father's education level and mother's education level are the influencing factors of ASPD. Male, Lisu nationality and single-child family were independent risk factors for positive ASPD screening, while age ≥ 19 years old and high school education were protective factors for ASPD.
