Background and aim: Studies have revealed a high prevalence of non-alcoholic fatty liver disease (NAFLD) among adult patients with mental disorders, as well as its associate risk factors, however little is known about these in pediatric population. The aim of the present study is to investigate the prevalence of NAFLD in pediatric inpatients with mental disorder, as well as to explore the risk factors. Methods: In this retrospective study, we included 1156 pediatric inpatients with mental disorder admitted to our hospital between January 2020 and December 2021, including inpatients with schizophrenia, bipolar disorder, depressive disorder and other mental disorders. Relevant clinical data were obtained from the electronic medical records. We calculated the prevalence rate of NAFLD, and compared NAFLD prevalence between gender, mental disorders types, antipsychotics use, and comorbidities. Multivariable logistic regression was used to examine risk factors associated with NAFLD. Results: The prevalence of NAFLD in pediatric inpatients with mental disorders was 7.35% (85/1156). Patients with NAFLD had senior age than those without NAFLD (15.33±1.75 vs 14.21±1.95 year-old, P<0.001). The NAFLD prevalence in participants with schizophrenia (12.11%) was higher than in participants with bipolar disorder (8.45%), depressive disorder (7.06%) and other mental disorders (2.97%)(p=0.002). The NAFLD prevalence was higher in participants who used antipsychotics (8.70%) than those who didn't (5.45%) (p=0.038). Multivariate analysis revealed that senior age, body weight (overweight/obese) and dyslipidemia were independent risk factors for NAFLD in pediatric inpatients with mental disorders. Conclusions: The NAFLD prevalence was is higher in those patients with schizophrenia and receiving antipsychotic medication. Metabolic factors and longer evolution may explain these differences.
