| Objective Studies in recent years have indicated that at least 11%-16% of children and adolescents suffer from one or more mental disorders,and studies in our country have also indicated that 17.5% of the overall prevalence is in the group of children and adolescents aged 6-16 years in our country,but only some of them are diagnosed and treated.Official data in China also point to an increasing trend in the proportion of children and adolescents hospitalized for mental illness.In recent years,the state has been paying more attention to the mental health of children and adolescents,and has issued several documents to strengthen the identification and treatment of mental disorders in children and adolescents.However,domestic and international surveys on mental disorders in children and adolescents are mostly prevalence surveys at the social level,and rarely involve the situation of children and adolescents who are hospitalized due to mental disorders.However,from a clinical point of view,the hospitalization rate of mental disorders may be more indicative of the severity of the disorders.This study mainly investigated the proportion of hospitalization,length of stay,age of admission,and gender share of major mental disorders in children and adolescents to provide reference for early intervention of the disorders and the distribution of medical resources in hospitals.Methods This study screened 5807 patients less than or equal to 18 years old in the child and adolescent wards of Anhui Provincial Mental Health Center from 2001 to2022,and the top four(83.1%)disorders were included based on the disorders they suffered,namely schizophrenia(SCZ)(37.2%),depressive disorder(DD)(20.3%),bipolar disorder(BD)((11.0%),and childhood emotional disorder(CED)(14.6%),and the percentage of hospitalization,length of stay,age of admission,and gender share were analyzed for each disease.The year of the novel coronavirus epidemic was also used as the selected time point to compare the change in hospitalization before and after the time point.Results 1.In terms of the proportion of hospitalizations,there was a significant downward trend in the proportion of hospitalizations for schizophrenia from2001-2022(Tj-t=26.5,z=-5.021,P<0.001),with Kendall’s τ-b correlation coefficient(rτ=-0.772,P<0.001).There was a significant upward trend in the proportion of hospitalizations for depressive disorders(Tj-t=202.0,z=4.882,P<0.001),Kendall’s τ-b correlation coefficient(rτ=0.752,P<0.001).There was no significant change in the proportion of hospitalizations for bipolar disorder(Tj-t=147.5,z=1.805,P=0.071).There was a significant upward trend in the proportion of hospitalizations for childhood emotional disorders(Tj-t=198.5,z=4.809,P<0.001),with Kendall’s τ -b correlation coefficient(rτ=0.768,P<0.001).2.In terms of length of stay,schizophrenia was significantly longer than the other three disorders(χ~2=667.640,P<0.001),whereas there was no significant difference between depressive disorders,bipolar disorder,and childhood emotional disorders.There was a decreasing trend in length of stay for schizophrenia(Tj-t=65.0,z=-2.835,P=0.004)and Kendall’s τ-b correlation coefficient(rτ=-0.441,P=0.004).There was no significant trend in length of stay for depressive disorders(Tj-t=20.5,z=0.524,P=0.600).There was no significant trend in length of stay for bipolar disorder(Tj-t=113.0,z=-0.141,P=0.888).There was no significant trend in length of stay for childhood emotional disorders(Tj-t=13.5,z=-0.943,P=0.345).3.In terms of age at admission,there was no significant trend in age at admission for schizophrenia(Tj-t=123.0,z=0.423,P=0.672).There was a significant downward trend in age at admission for depressive disorders(Tj-t=2.0,z=-3.336,P=0.001)and Kendall’s τ-b correlation coefficient(rτ=-0.889,P=0.001).There was a significant upward trend in age at admission for bipolar disorder(Tj-t=181.0,z=3.697,P<0.001),Kendall’s τ-b correlation coefficient(rτ=0.570,P<0.001).There was no significant trend in age at admission for childhood emotional disorders(Tj-t=13.0,z=-1.043,P=0.297).4.In terms of gender prevalence,there was a significant upward trend in the gender prevalence of hospitalizations for schizophrenia(Tj-t=180.0,z=3.667,P<0.001)and Kendall’s τ-b correlation coefficient(rτ=0.564,P<0.001)for females.There was a significant upward trend in female inpatients with depressive disorders(Tj-t=33.0,z=3.128,P=0.002),Kendall’s τ-b correlation coefficient(rτ=0.833,P=0.002).There was no significant trend in female inpatients with bipolar disorder(Tj-t=118.0,z=0.142,P=0.887).There was an upward trend in female inpatients with childhood emotional disorder(Tj-t=32.0,z=2.919,P=0.004)and Kendall’s τ-b correlation coefficient(rτ=0.778,P=0.004).5.Around the selected time points,the None of the four diseases showed a trend in the hospitalization percentage that was again higher than the original.In terms of length of stay,the length of stay for schizophrenia and childhood emotional disorders showed a decreasing trend from the increasing trend before the time point,while the decreasing trend for depressive disorders and bipolar disorders showed a decreasing increase.In terms of age at admission,there was an increasing trend in the age at admission for schizophrenia and bipolar disorder,while there was a moderating trend in the age at admission for depressive disorders and childhood emotional disorders.In terms of admission gender,the proportion of females with schizophrenia and bipolar disorder showed an increasing trend to a decreasing trend,while the proportion of females with depressive disorder and childhood emotional disorder showed a moderating trend to an increasing trend.Conclusion Although there is a significant downward trend in the percentage of schizophrenia hospitalizations,it remains the main psychiatric disorder in children and adolescents.It should be noted that there is a significant increasing trend of depressive disorders and childhood emotional disorders.In addition,the proportion of female patients in hospitalization is increasing,which requires continuous attention.The impact of novel coronavirus on hospitalization needs to be further studied. |
