A Cluster Analysis of the Circumstances of Death in Suicides in Hong Kong
Publisher: Wiley
Date: 10-2007
DOI: 10.1521/SULI.2007.37.5.576
Abstract: Classification of suicides is essential for clinicians to better identify self-harm patients with future suicidal risks. This study examined potential subtypes of suicide in a psychological autopsy s le (N = 148) in Hong Kong. Hierarchical cluster analysis extracted two subgroups of subjects in terms of expressed deliberation assessed by the Beck Suicide Intent Scale (SIS). The first group was associated with charcoal burning suicide, no psychiatric illness, indebtedness, better problem-solving ability, chronic stress, and higher overall SIS scores. The second group was associated with jumping from a height, psychotic disorders, psychiatric treatment, acute stress, and lower overall SIS score. The existence of a substantial cluster of subjects with lower expressed intent and preparation has important implications for the performance of the SIS as a predictive tool. Suicide prevention strategy may have to target potential subgroups with specific approaches.
Suicide in Hong Kong: a case-control psychological autopsy study
Publisher: Cambridge University Press (CUP)
Date: 30-03-2006
DOI: 10.1017/S0033291706007240
Abstract: Background. The relative contribution of psychosocial and clinical risk factors to suicide among Chinese populations is an important issue. In Hong Kong, this issue requires vigorous examination in light of a 50% increase in suicide rate between 1997 and 2003. Method. Using a case-control psychological autopsy method, 150 suicide deceased were compared with 150 living controls matched by age and gender. Semi-structured interviews were conducted with the next-of-kin of the subjects. Data were collected on a wide range of potential risk and protective factors, including demographic, life event, clinical and psychological variables. The relative contribution of these factors towards suicide was examined in a multiple logistic regression model. Results. Six factors were found to significantly and independently contribute to suicide: unemployment, indebtedness, being single, social support, psychiatric illness, and history of past attempts. Conclusions. Both psychosocial and clinical factors are important in suicides in Hong Kong. They seem to have mediated suicide risk independently. In addition, socio-economic adversities seem to have played a relatively important role in the increasing suicide rate in Hong Kong.
Suicidality in Chinese adolescents in Hong Kong: the role of family and cultural influences
Publisher: Springer Science and Business Media LLC
Date: 04-10-2008
DOI: 10.1007/S00127-008-0434-X
Abstract: Adolescent suicidal ideation has found to predict suicidal behaviors and psychopathology in adulthood. Previous studies focused solely on the medical and environmental risk factors, which were insufficient to give a holistic picture of adolescent suicidality. To assess the role of affective and cognitive attributes in the identification and prevention of adolescent suicidal ideation. A community s le of 511 participants (age 15-19 years) were asked to indicate their suicidality in the 12 months and in their lifetime. Generalized estimating equation regression models were used to examine the effect of psychosocial and socio-environmental correlates in relation to adolescent suicidal ideation. The data show that perceived responsibilities for family was the only protective factor, while a coping mechanism by behavioral disengagement, severity of depressive symptoms, a history of deliberate self-harm, chronic physical illness or pain, media reporting of suicide news, and low household income were the risk factors for adolescent suicidal ideation. The results suggest that a multilayer effort for preventing adolescent suicide is needed by providing support for children in deprived families enhancing life skills in the teens strengthening family relationship improving mental and health services and promoting responsible media reporting on suicide.
A Study of Sexual Satisfaction and Frequency of Sex Among Hong Kong Chinese Couples
Publisher: Informa UK Limited
Date: 14-05-2008
DOI: 10.1080/00224490801987416
Abstract: There have been several studies in Western societies on the causes and consequences of sexual satisfaction within marriage. Little is known, however about the marital sexual relationship in Chinese societies. Moreover, most published studies used married in iduals rather than married couples as participants. The present study examined data from a well-established knowledge, attitude, and practice (KAP) survey of 1,124 Hong Kong Chinese couples on martial sexual relationship. A conceptual model was tested using structural equation modeling (SEM). Interest in sex was found to be the strongest predictor of both sexual satisfaction and frequency of sex for both husbands and wives. Among the sociodemographic variables, the following two were significantly associated with lower frequencies of sex: for wives, that of having a full-time job and for husbands, the factor of age. Theoretical implications for research on the interplay among culture, marriage, and sex in non-Western societies are discussed.
Psychiatric history modifies the gender ratio of suicide: An East and West comparison
Publisher: Springer Science and Business Media LLC
Date: 25-07-2009
DOI: 10.1007/S00127-008-0413-2
Abstract: Gender ratios of suicide rates differ greatly across countries. Victoria has a high male:female ratio in suicide that is typical in English-speaking and European countries, while in Hong Kong the low ratio is similar to other SouthEast Asian countries. This study investigates the effect of gender in the psychiatric and non-psychiatric populations to examine how psychiatric history may modulate the effect of gender in these two different communities. Review of coronial documentation of all suicide cases in 2000 in Hong Kong and Victoria, Australia. Log-linear model was used to test the gender-psychiatric history-location interaction. Gender difference in suicide was narrower in victims with psychiatric history than those without in both communities, albeit gender remained to have an effect even among those with a psychiatric history in Victoria. The impact of cultural- and gender-specific factors is most apparent in suicide cases with no prior psychiatric history in Victoria: the male:female ratio was as high as 8:1 in this group of victims. Log-linear model results show that the gender-psychiatric history-location interaction was statistically significant. The gender differentials in suicide rates in these two communities are mainly driven by gender's effect in the population with no psychiatric history. Severe clinical conditions can override some, but not all, of gender's effects in Victoria. Suicide prevention effort should target gender-specific factors to prevent suicides in men without history of psychiatric disorders.
