OBJECTIVETo investigate the prevalence of attention deficit hyperactivity disorder (ADHD) and behavior problems among school-age children in Shenzhen City of Guangdong.

METHODSA total of 10553 students in Grades 1-6 from different primary schools in Shenzhen City were assessed by Conners Parent Symptom Questionnaire (PSQ) and Conners Teacher Rating Scale (TRS). Children showing abnormalities according to PSQ or TRS were further assessed according to the diagnostic standard for ADHD as laid out in the diagnostic and statistical manual for mental disorders- 4th edition (DSM-Ⅳ).

RESULTSA total of 8193 PSQ and TRS assessments were completed. The children were aged from 7 to 13 years. The total prevalence rate was 7.60% by PSQ and 5.59 % by TRS. Four hundred and forty-two children were diagnosed having ADHD by DSM-Ⅳ, with a prevalence rate of 5.39%. There were significant differences in the prevalence rate of ADHD among children aged 7 to 13 years (χ2=21.613, P<0.05). In children aged 7 to 9 years, the prevalence rate was higher (above 6%). The prevalence rate of ADHD in boys was significantly higher than in girls (6.65% vs 3.12%; P<0.05). Impulsion and hyperactivity (79.6%), learning (60.6%) and conduct disorders (52.0%) were the main behavioral problems in children with ADHD. The prevalence of learning disorders was higher in girls than in boys. Conclusions The prevalence rate of ADHD in children from primary schools in Shenzhen City is 5.39%, and it is higher in children aged 7 to 9 years. Boys have a higher prevalence rates of ADHD than girls. Impulsion and hyperactivity, learning and conduct disorders are common problems in children with ADHD.

PURPOSE: Our purpose was to investigate psychological problems and clinical outcomes in children with psychogenic non-epileptic seizures (PNES). MATERIALS AND METHODS: We retrospectively reviewed the data of 25 patients who were diagnosed with PNES between 2006 and 2012. RESULTS: Twenty-five children with PNES, aged 8 to 19 years (mean 13.82), were referred to psychiatrists for psychiatric assessment. On their initial visit, 72% of patients had comorbid psychological problems, including depression, anxiety, conduct disorder, adjustment disorder, Attention Deficit Hyperactivity Disorder, schizophrenia, and bipolar disorder. Among these, depression was the most frequent (36%). Predisposing and triggering factors included familial distress (40%), social distress (24%), and specific events (20%). The following treatment was advised based on the results of the initial psychological assessment: 3 patients regularly visited psychiatric clinic to assess their clinical status without treatment, nine underwent psychotherapy, and 13 received a combination of psychotherapy and psychopharmacological therapy. At the mean follow-up of 31.5 months after diagnosis, 20 patients (80%) were event-free at follow-up, three (12%) showed reduced frequency, and two (8%) experienced persistent symptoms. CONCLUSION: The outcomes of PNES in children are much better than those in adults, despite a high rate of psychological comorbidities.

OBJECTIVETo explore risk factors and protective factors of sensory integrative dysfunction (SID) among preschool and school children in Beijing, and to identify potential risk factors of SID.

METHODSThree hundred and ten kindergarten children were investigated twice in 1993 and 1999 by "The Child Sensory Integration Check List" and "General Information Questionnaire". A nested case-control study was carried out by single variable and multivariate conditional logistic regression analysis to find out the risk factors of SID.

RESULTSIn the SID incidence group, the risk factors of SID were edema during pregnancy (OR = 7.06), paternal age (OR = 1.28), suffering from diseases before 3 years old (OR = 1.13), while the protective factor was family support network during school age (OR = 0.54). In the SID self-recovery group, the risk factors of SID were suspected attention-deficit hyperactivity disorder (ADHD) among maternal cousins (OR = 3.02), social ethos (OR = 1.69), consistency of parental discipline (OR = 1.45), while the protective factors were living condition and environment for entertainment (OR = 0.37), parental care during school age. In the SID negative group, the risk factors of SID were maternal contracted pelvis (OR = 3.45), less chance in enjoying audio and video entertainment during school age (OR = 1.98), suspected ADHD among paternal cousins (OR = 1.89), consistency of parental discipline (OR = 1.75), suspected ADHD among maternal cousins (OR = 1.48), paternal occupation during school age (OR = 1.19), while the protective factors were family support network (OR = 0.56) and maternal educational background (OR = 0.38) during preschool age.

CONCLUSIONOur data showed that the risk factors of child SID were mainly associated with biological and genetic factors. Psychosocial factors seemed to be the secondary risk factors of SID.
