Among the 125 children aged 6-14 years from big families resided in various typesof dwelling,results show that significantly more in-door activities of children with their family mem-bers was found in those from high rise,but the longest time of out-door activities of children was foundin those from pinfang.No significant difference in health condition was observed among children fromvarious types of dwelling and little influence of dwelling type was yet observed upon health conditionof children so far.

Objective: To explore the relationship between parental rearing behavior and personality disorder. Method: Descriptive study was carried out in one key-university in Beijing. Two thousand two hundred and five freshmen were investigated with Personality Diagnostic Questionnaire-Revised (PDQ-R) and EMBU scale. Fifty-five personality disorder cases were diagnosed by International Personality Disorder Examination (IPDE). Results: The scores of emotional warmth, over-protection, and favoring subject of the maternal were higher than those of the paternal. Parental scores of EMBU factors were highly correlative. The scores of rejection, overprotection, favoring subject in personality disorder cases were significantly higher than those in control group, while the score of emotional warmth was significantly lower. Conclusion: Inappropriate parental rearing behavior is a risk factor of personality disorder.

Objective:To explore the effect of parental rearing behavior and related factors of personality dysfunction in adolescents Method:By means of stratified cluster sampling, 9574 students from 25 representative senior high schools in urban and rural areas of Beijing were investigated by PDQ-4 (personality diagnostic questionnaire-4), EMBU and general information questionnaire A case control study based on community was carried out afterwards The cases were the students whose total PDQ-4 score was 42 (means?1 645s) or more The controls were students whose total PDQ-4 score was 25 (means) or less Cases of personality dysfunction (n=531) were individually matched with 1062 controls by age and gender in ratio of 1:2 The single variable and multivariate conditional logistic regression analyses were performed to screen out the risk factors of personality dysfunction Result: The single variable conditional logistic regression analysis revealed that parental rejection, overprotection, favoring subject, rural area, type of school, poor parental relationship and single parent family increased risk of personality dysfunction, while parental emotional warmth was a protective factor The multivariate conditional logistic regression analysis gave the same results with OR=11 43 for parental rejection, OR=7 68 for overprotection, OR=13 94 for rural area, OR=4 15 for poor parental relationship, and OR=0 50 for parental emotional warmth There was no association between personality dysfunction and nationality, family income, single child family or level of parental education Conclusion:Personality dysfunction in adolescents is closely related to family environment

Objective: To compare the difference of family environment and other factors having influence on academic achievement of university students between freshmen in one key-university and another un-key-university Methods: 3995 freshmen (2214 from a key university of Beijing, 1781 from an un-key university of inner Mongolia) were investigated with the EMBU scale and the General Information Questionnaire Results: The freshmen of the two universities had different experience in nearly all aspects investigated, including parental rearing behavior, educational levels, occupation, family type, family economic status, etc Parenting styles of parents, poor parental relationship, lower income and educational level, residency and race had effect on academic achievement of the freshmen Conclusion:Freshmen in different universities have different family environment and parental rearing

Objective:To study the epidemiological features of internet addiction disorder(IAD)in high school students in Beijing and explore the related factors.Methods:A stratified cluster sampling method was used.Totally 5100 high schools students were measured with the Internet Addiction Scale,Personality Diagnostic Questionnaire and Egna Minnen av Bardndoms Uppfostran(EMBU).Results:(1)The prevalence of IAD was 8.8% in high school students in Beijing.(2)Logistic regression analysis indicated that the risk factors of IAD were male,school area in urban area,parents' divorce,parents' refusal,parents' over-protection,paranoid personality disorder,avoidant personality disorder,antisocial personality disorder and histrionic personality disorder.The protective factor was parents' emotional warmth.Conclusion:It should be paid more attention to internet addiction disorder IAD in high school students in Beijing.Prevention and intervention should be conducted to the risk factors of internet addiction disorder IAD.

Objective: To evaluate feasibility of informant questionnaire of the Community Screening Instrument for Dementia(CSID) and related factors in a sample of community elderly population, and to investigate prevalence of suspectable dementia in the sampled people.Method: A total of 2267 people aged 65 and above in one rural area and one urban area in Beijing were recruited and their informants were assessed by the CSID informant questionnaire.Validity of CSID were evaluated according to the computerized diagnosis of 10/66 project and ICD-10.Result:The split-half reliability of CSID informant questionnaire was 0.85 and the consistency was more than 0.8.When the cutoff point of CSID was 6 or more, sensitivity was 86.2% and specificity was 93.2%.At meantime, the prevalence of suspectable dementia was 9.1%.Logistic regression analysis showed that the information obtained from informant as a spouse and from informant who lived in urban area was correlated with positive diagnosis of dementia.Conclusion:CSID informant questionnaire is valid as a screening instrument of dementia.Information from spouse is useful to identify the change of cognitive function of the elderly.

Objective:To explore the traits of gray matter volume in general anxiety disorder (GAD)and ob-sessive compulsive disorder (OCD)by using magnetic resonance imaging (MRI)technique.Methods:Twenty-eight GAD,25 OCD and 39 normal controls were recruited.All patients were met the Diagnostic and Statistical Mannal of Mental Disorders,Fourth Edition,Text Revision (DSM-IV-TR)or the International Statistical Classifica-tion of Disease and Related Health Problems Tenth Revision (ICD-10)diagnostic criteria for GAD or OCD.All subjects underwent structural MRI scan.The severity of anxiety and OCD symptoms were rated in all patients with the Hamilton Anxiety Rating Scale (HAMA)and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS).The gray matter volume (GMV)was compared between all groups by using the voxel-based morphometry (VBM)a- nalysis.The correlation analysis between GMV and total scores of HAMA and Y-BOCS was performed in GAD and OCD.Results:The GMV was increased in regions including left anterior cingulate cortex in GAD (P =0.016,small volume correction),while only decreased GMV was observed in OCD in bilateral orbitofrontal cortex (OFC)(P <0.001,uncorrected).GAD had larger GMV than OCD in several regions including bilateral OFC (P <0.001,un-corrected).The higher total score of HAMA was associated with increased GMV of right temporal cortex in GAD, and with the GMV of OFC in OCD (P <0.001,uncorrected).Conclusion:No sharing of GMV abnormalities in GAD and OCD was observed in the current study.The traits of brain structure and the potential neural substrate of anxiety symptom in GAD and OCD may be significantly different.

Objective:To explore the association between religiosity and suicide ideation,in order to provide evidence for suicide prevention in the community residents.Methods:Using the data from the epidemiological sur-vey of mental disorders in Ningxia,the association between religiosity and the suicidal ideation was ana-lyzed.Logistic regression model was used to detect the associated factors.Results:Univariate statistical analysis showed that females,rural residence,residents living in plain area,illiterates and being married had higher risks of suicidal ideation (P <0.05).Logistic regression analysis showed that religion affiliation (OR =0.96,95%CI:0.74-1.24),religion attendance (OR =0.82,95%CI:0.60 -1.11),religion importance (OR =1.08,95%CI:0.83 -1.40),religiosity degree (OR =0.80,95%CI:0.57 -1.12)in suicidal ideation group were not significantly differ-ent to those in the control group (P >0.05).Conclusion:The results indicate that there is no statistical association between religiosity and suicidal ideation in Ningxia community residents.
