3、stand changes over time in the characteristics and treatment of children with ADHD seen at specialty psychiatric clinics in China.Methods:For each year from 2000 through 2011,250 charts of patients who made their initial visit to the Child and Adolescent Psychological Counseling Clinic of the Shangh

4、ai Mental Health Center were randomly selected.Among the 3000 selected patients,998(33%)had a diagnosis of ADHD.Results:About 80%of the ADHD patients were male and the majority of them fell ill prior to the age of seven.The mean(sd)age at the time of first attendance at the clinic was 10.0(2.6)years

5、 and the mean duration of illness at the time of the initial visit was 2.9(1.2)years;both of these values decreased significantly over time.About 20%of them were non-residents of Shanghai and about 11%had comorbid psychiatric diagnoses(primarily depression and tic disorder);both of these proportions

6、 increased significantly over time.Among the 576(58%)who visited the clinic more than once,77%were treated with central nervous system stimulants,but the proportion administered behavioral treatments(either solely on in combination with medications)increased significantly over time.Conclusion:ADHD r

9、ment of this disabling condition.1.IntroductionAttention-Deficit/Hyperactivity Disorder(ADHD)was first recognized as a distinct condition in the late 1960s.Over the last two decades there have been several improvements in the diagnostic criteria for the disorder and in the interventions available to

10、 treat the condition.1-3 In China,in parallel with the recent rapid development of child and adolescent psychiatry,ADHD has been recognized as one of the most common psychiatric disorders among children.4,5 To describe secular trends in the characteristics of ADHD treatment in China,the current pape

12、Figure 1.Data were abstracted from the case records of patients who sought treatment from January 2000 to December 2011 at the Child and Adolescent Psychological Counseling Clinic of the Shanghai Mental Health Center at the Shanghai Jiao Tong University School of Medicine.Two hundred and fifty patie

13、nts first treated in the clinic during each of the twelve years from 2000 to 2011 were randomly selected from all patients first treated in each year using computer-generated random numbers.As shown in Table 1,a total of 998(33.3%)of the 3000 medical records identified were for children diagnosed wi

14、th ADHD.236 Shanghai Archives of Psychiatry,2013,Vol.25,No.43.Results 3.1 Characteristics of the identified ADHD patientsThe characteristics of the ADHD patients over the 12 years considered are shown in Table 2.Over the 12-year-period the proportion of patients with the ADHD diagnosis varied from a

15、 low of 26.4%in 2005 to a high of 46.8%in 2006.Thus,there were significant variations in the proportion of patients with the diagnosis over the 12 years(2=44.68,df=11,p0.001).However,there was no clear increasing or decreasing trend in the proportion of patients with the ADHD diagnoses over time(2tr

16、end=0.02,p=0.877).Only 2 of the 998 ADHD patients(0.2%)received inpatient treatment and both had comorbid conditions(one had conduct disorder and the other had an eating disorder);in comparison to this,4.1%(82/2002)of the non-ADHD patients received inpatient treatment.Among children diagnosed with A

17、DHD over the 12-year period considered,836 were males and 162 were females,which results in a male:female ratio of 5.2:1.This gender ratio did not vary significantly over the 12 years assessed(2=14.88,df=11,p=0.109).These patients included 800 from Shanghai and 198 from other cities or provinces,whi

18、ch results in an overall ratio of local to non-local patients of 4:1.This local:non-local ratio varied significantly over the 12 years from a high of 25.1:1 in 2001 to a low of 1.8:1 in 2008(2=40.96,df=11,Medical charts of children treated at the Child and Adolescent Psychological Counseling Clinic

24、onThe information abstracted from the charts included the gender,age,residence(Shanghai v.elsewhere),duration of symptoms at the time of the initial visit,diagnosis(at the time of the final visit),number of clinic visits,type of treatment(medication alone v.non-pharmacological methods v.both pharmac

25、ological and non-pharmacological methods),and clinical status at the time of the last recorded visit.The diagnoses reported in the charts were made by an attending level(or higher)psychiatrist using the American Psychiatric Associations Diagnostic and Statistical Manual of Mental Disorders 4th Editi

26、on(DSM-IV).7 To maintain the anonymity of the collected data,patients names,addresses and contact information were not included in the extracted information.2.3 Statistical methodsA database created using EXCEL was analyzed using SPSS statistical software.Proportions of patients with different chara

27、cteristics in the 12 years considered were assessed using Chi-square tests and trends in changes over these 12 years were assessed using Chi-square for trend analyses.The age of first treatment at the clinic,the duration of illness(reported by the accompanying family member),and the estimated age of

28、 onset were not normally distributed,so we used Mann-Whitney rank tests to assess changes in these values from the first six-year period(2000 through 2005)to the second six-year period(2006 through 2011)considered in the analysis.237 Shanghai Archives of Psychiatry,2013,Vol.25,No.4p0.001);the propor

29、tion of local patients from Shanghai decreased significantly over time(2trend=15.26,p0.001).Among the 998 patients with ADHD,the mean(sd)age of first treatment at our clinic was 10.0(2.6)years,the mean duration of illness(as reported by the parents)at the time of first treatment at our clinic was 2.

30、9(1.2)years and,thus,the estimated mean age of onset was 7.1(2.3)years.The age at the time of the first attendance at the clinic of patients seen in the second five-year period(2006-2011)(median=9.2 year,interquartile range=7.6-11.5 years)was significantly younger than that of patients seen in the f

31、irst five-year period(2001-2005)(median=10.2 years,interquartile range=7.9-12.4 years;Mann-Whitney U=4.69,p0.001).In parallel with this earlier age of attendance at our clinic over time,the duration of illness at the time of coming to the clinic decreased over time:the median(interquartile range)dur

32、ation of illness at the time of first clinic visit among patients first seen from 2000 through 2005 was 4.0(1.0-6.0)years while that of patients seen from 2006 through 2011 was 3.0(1.0-5.0)years(Mann-Whitney U=3.80,p0.001).The estimated age of onset did not vary significantly over time.Overall,576 o

33、f the 998 ADHD patients(57.7%)had an onset of illness prior to 7 years of age,397(39.8%)first fell ill from 7 to 12 years of age,and 25(2.5%)first fell ill after the age of 12.Among these 998 patients,10.6%(106 individuals)had comorbid psychiatric conditions.The proportion of patients with comorbid

34、conditions varied over the 12 years from a low of 6.5%in 2002 to a high of 25.4%in 2011(2=20.94,df=11,p=0.034);there was a significantly increasing trend in the proportion of patients with comorbid diagnoses(2trend=4.05,p=0.044).The specific comorbid diagnoses in the ADHD patients are shown in Table

35、 3.The most common comorbid diagnoses were tic disorders and mood disorders(primarily depression);these two disorders accounted for 75.5%(80/106)of all comorbid conditions recorded.Increases in the proportion of patients with a comorbid mood disorder over time was the main factor that lead to the in

36、crease in the proportion of patients with any comorbid condition over time.3.2 Care-seeking and treatment of ADHD patientsAmong the 998 patients,42.3%(n=422)only made a single visit to the clinic;57.7%(n=576)made two or more visits(15.0%made two visits,8.4%made three visits and 34.3%made more than t

37、hree visits).The proportion of patients with multiple visits varied from a low of 29.5%in 2000 to a high of 89.4%in 2005.There is statistically significant variation in the proportion of patients with Table 2.Characteristics of patients treated at the Child and Adolescent Psychological Counseling Cl

44、ADHD patients who made multiple visits to the clinic that had comorbid diagnoses(70/576,12.2%)was higher than the proportion of ADHD patients who only made a single clinic visit that had comorbid diagnoses(36/422,8.5%),but this difference was not statistically significant(2=3.37,p=0.067).The proport
