RESUMO
OBJECTIVE: This is an epidemiological study to determine the prevalence of suicidal behavior and its association with generalised anxiety disorder (GAD) and major depressive disorder (MDD) in a nationally representative sample. METHOD: Suicidal ideation, plans and attempts were assessed in face-to-face interviews of respondents selected by a multistage probability sampling using items on suicidality from the WHO SUPRE-MISS questionnaire. The Mini International Neuropsychiatric Interview (MINI) was used to generate DSM-IV diagnoses of GAD and MDD. A total of 19309 subjects were studied. Multivariate regression analysis was conducted controlling for demographic characteristics such as age, gender and ethnicity. RESULTS: The prevalence estimates for suicide ideation, plans and attempts were 1.7% (95% CI: 1.4-1.9), 0.9% (CI: 0.7-1.1) and 0.5% (CI: 0.4-0.7) respectively. Younger people (16-24 years) had higher risk of suicidal behavior (OR: 2.6, CI: 1.08-6.2). Females (OR: 1.6, CI: 1.2-2.1) and Indians (OR: 3.3, CI: 2.2-4.9) also had higher risk. CONCLUSION: The prevalence of suicidal behavior in Malaysia is low, but it broadly corresponds to the pattern described in other countries. This national study confirms that Malaysians of Indian descent have much higher rates of suicidal behavior than other groups. The younger age group, females and the Indian ethnic group would need focused preventive efforts.

OBJECTIVES: The aim of this paper is to identify at-risk groups for a focused suicide prevention program for Malaysia. METHODS: Data from 20,552 persons aged 16 years and above (males 45.9%), was obtained using stratified, random sampling in a national survey of psychiatric morbidity using locally validated General Health Questionnaire (GHQ-28) which included questions on suicidal ideation. RESULTS: The overall prevalence of suicidal ideation (SI) was 6.3%, CI 6.1-6.8 (n=1288). Logistic regression analysis was performed with age, ethnicity, gender, urban/rural residence, age group, marital status, household income, type of household, presence of chronic pain, social dysfunction, somatic, anxiety or depressive symptoms, obesity, and chronic medical illnesses as independent variables. Only Insomnia, Religion, Marital Status, Depression, Social Dysfunction and Anxiety were seen to be significant predictors. Prevalence of SI was significantly higher among Indians (11.0%, CI 9.5-12.5), especially those of the Hindu faith (12.2%, CI 10.5-14.0), Chinese (9.7%, CI 8.8-10.7) and those having depressive symptoms. CONCLUSION: In a developing country with competing priorities, prudent allocation of resources requires focusing suicide prevention efforts on treating depression in vulnerable groups.
