INTRODUCTION: The rising rate of adolescent suicide, and the burden of self-harm and mental health disorders, pose significant threats to Singapore's future health outcomes and human potential. This study sought to examine the risk profile and healthcare utilisation patterns of Singaporean adolescents who presented to the emergency department (ED) for suicidal or self-harm behaviour. METHOD: A retrospective review of medical records for patients aged 10 to 19 years who visited Singapore's KK Women's and Children's Hospital ED for suicidal or self-harm attempts from January to December 2021 was conducted. RESULTS: A total of 221 patients were identified, with a predominance of female patients (85.5%) over males (14.5%). The mean age was 14.2 ± 1.4 years. Intentional drug overdose (52.0%) was the most commonly used method. Significantly more females presented for intentional paracetamol overdose (46.6% versus [vs] 28.1%, P=0.049), whereas jumping from a height was more common among males (18.8% vs 5.8%, P=0.022). The most frequently observed mental health challenges were stress-related and emotional coping difficulties (50.7%), followed by mood and anxiety symptoms (53.4%). A history of self-harm and suicidal behaviours were the most common psychosocial risk factors. Within the year prior to their ED presentation, 15.4% had accessed healthcare services for mild medical ailments, 19.5% for medically unexplained symptoms, and 17.2% for previous self-harm or suicide attempts. CONCLUSION Most cases involved psychosocial and emotional regulation difficulties, some of which displayed sex-specific patterns, rather than complex psychiatric disorders. The identified predictive factors can help inform Singapore's National Mental Health and Well-being Strategy, to guide targeted and transdiagnostic interventions in schools and community settings.

OBJECTIVES: Non-suicidal self-injury (NSSI) is a common mental health and behavioral issue among adolescents. This study aims to investigate the developmental trajectory of adolescent NSSI and gender differences, providing a foundation for better prevention and intervention. METHODS: A longitudinal study was conducted using the Adolescent Self-Injury Scale (ASIS) in a cohort of 1 042 junior high school students from 3 middle schools in Zhangjiajie, Hunan Province. Participants were surveyed 3 times at 6-month intervals. A latent growth curve model was constructed using Mplus8.0 to examine the development trajectory of NSSI, and multi-group comparisons were used to assess gender differences. RESULTS: Detection rates of NSSI at the 3 time points were 43.95%, 44.43%, and 38.36%, respectively. Mean of the intercept factor of the LGCM for adolescent NSSI behavior was 9.540 (P<0.001), and the mean slope was -2.297 (P<0.001). Both the variances of the intercept (σ²=169.431, P<0.001) and slope (σ²=141.981, P<0.001) were significant, with a significant negative correlation between intercept and slope (r=-0.559, P<0.001). There were no statistically significant gender differences in initial level or rate of change of NSSI behaviors (P>0.05). CONCLUSIONS NSSI is relatively prevalent among adolescents, with female adolescents experiencing more severe NSSI. Individual differences exist in both the initial level and rate of change of NSSI, and overall, adolescent NSSI shows a decreasing trend over time. No significant gender differences were found in the trajectory of change.

INTRODUCTION: The understanding of gender dysphoria (GD) in children and adolescents is limited in Singapore. This study aims to review the presentation of GD in an outpatient psychiatric clinic, to gain insights into its prevalence and associated factors. METHOD: We conducted a retrospective review of medical records for patients diagnosed with GD according to criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth and Fifth editions, at the clinic between 1 January 2017 and 31 December 2021. We collected and analysed demographic, medical and other GD-specific clinical variables. RESULTS: The study included 107 participants (mean age 16.6 years), comprising 47 natal males and 60 natal females. The prevalence of GD was found to be 1:5434 (0.019%). Incidence rates increased from 2.17 to 5.85 per 100,000 population between 2017 and 2021. The mean age of diagnosis was 15.6 years, with an average delay of 5 years between experiencing gender identity-related concerns and seeking formal assistance. Approximately 45% of participants reported social and physical transitions, and 20.6% reported self-harm or suicidal thoughts. CONCLUSION The study highlights the presentation of GD in an under-researched Asian setting. Supporting individuals with GD in Asia requires sensitivity to cultural and societal factors with a holistic approach to individual well-being.

OBJECTIVE: To present an approach to phenotyping ACEs and explore the association between ACEs and adolescent health risky behaviors based on the social context of China. METHODS: Totally, 5,726 adolescents aged 12-18 years were investigated about their ACEs in the family, peer, school, and personal domains and the occurrence of six types of risky health behaviors (i.e., smoking, drinking, sexual intercourse, self-harm, and suicidal ideation and attempts). Latent class analysis (LCA) was used to explore the ACE patterns. RESULTS: Six latent classes of ACEs were identified, including low adversity, school adversity, school adversity and peer victimization, peer victimization, maltreatment and peer victimization, and high adversity, and associated with risky health behaviors in adolescents. Being physically punished by a teacher, experiencing sexual abuse, and experiencing family trauma most strongly differentiated from the six ACE classes and were correlated with an increased risk for risky adolescent health behaviors. CONCLUSION This study supports a positive association between ACEs and risky adolescent health behaviors. Peer victimization, school adversity and associated contexts need to be considered in future ACE studies.

From September 2017 to February 2018, 650 disabled children and adolescents aged 6-to 17-year-old in Beijing were matched 1∶1 to those in normal physical condition with same age, gender and place of residence. All children and adolescents were investigated for self-injury status in the last year to understand the difference of self-injury incidence between groups. Multivariate unconditional logistic regression model was applied for exploring relevant factors of self-injury of children and adolescents. This study found that the disability, insufficient sleep, difficulty falling asleep, and sleeping late were associated with self-injury of children and adolescents.

INTRODUCTIONThe prevalence rate of anorexia nervosa is lower in Asia than in the West, although studies have found that it is on the rise in Asia. This study aims to present the clinical profile of patients presenting with anorexia nervosa in Singapore.

METHODSThe present study used archival data from the Eating Disorder Programme registry of the Department of Psychiatry, Singapore General Hospital, Singapore. Patient records from 2003 to 2010 were collected and analysed. Presenting characteristics of the patients were also compared with those of another local study conducted eight years earlier.

RESULTSFrom 2003 to 2010, a total of 271 patients were diagnosed with anorexia nervosa by a psychiatrist in our hospital. Of these, 251 (92.6%) were female and 238 (87.8%) were Chinese. Our patients had a lower mean weight (36.83 kg, p < 0.001) and a lower mean body mass index (BMI) (14.43 kg/m(2), p < 0.001) than patients from the previous local study. Almost half of all our patients (n = 135, 49.8%) were diagnosed with at least one psychiatric comorbidity and 50 (18.5%) had a history of self-harm.

CONCLUSIONThe presenting characteristics of our study cohort were similar to those of the Western population. However, the lower presenting weight and BMI in our cohort indicates that cases seen today are more severe than those seen eight years ago. Therefore, it is important to put in place prevention programmes to help adolescents cultivate a healthy body image as well as early intervention programmes to improve detection rates and treatment outcomes.

The relationship between suicidality and the loudness dependence of auditory-evoked potentials (LDAEP) remains controversial. This article reviews the literature related to the LDAEP and suicide in patients with major depressive disorder, and suggests future research directions. Serotonergic dysfunction in suicidality seems to be more complicated than was originally thought. Studies of suicide based on the LDAEP have produced controversial results, but it is possible that these are due to differences in study designs and the smallness of samples. For example, some studies have evaluated suicide ideation and the LDAEP, while others have evaluated suicide attempts and the LDAEP. Furthermore, some of the latter studies enrolled acute suicide attempters, while others enrolled those with the history of previous suicide attempts, irrespective of whether these were acute or chronic. Thus, a more robust study design is needed in future studies, for example by evaluating the LDAEP immediately after a suicide attempt rather than in those with a history of suicide attempts and suicide ideation in order to reduce bias. Moreover, genuine suicide attempt, self-injurious behaviors, and faked suicide attempt need to be discriminated in the future.

INTRODUCTIONDeliberate self-harm (DSH) is frequently seen in adolescents with a range of mental health problems. The prevalence and features of DSH vary among different countries and settings. This study examines the prevalence of self-harm in a sample of adolescents seen at a psychiatric outpatient clinic in Singapore.

METHODSInformation regarding self-harm, as well as its associated demographic and clinical risk factors, was extracted from the clinical records of 542 consecutive, new patients, aged 12-19 years, who presented between 2006 and 2010.

RESULTSDSH was reported in 23.6% of patients, and was positively associated with the female gender (odds ratio [OR] 4.54), mood disorders (OR 4.58), adjustment disorders (OR 3.41) and regular alcohol use (OR 4.80). However, there was no association with parental marital status, anxiety disorder, habitual smoking or family history of psychiatric illness.

CONCLUSIONDSH is a significant clinical problem that may be influenced by biological and clinical factors. Adolescents presenting with DSH should be examined for mood and alcohol use disorders.

During visits to emergency medical facilities, the primary care of and risk identification for individuals who have attempted suicide is considered an important element in suicide prevention. With the ultimate goal of helping to prevent suicide, the aim of the present study was to determine the characteristics of patients with self-inflicted injuries who presented in the emergency department. Patients with self-inflicted injuries who visited 1 of 3 sentinel emergency medical centers from 2007 through 2009 were included in the study. The characteristics, methods, and reasons for suicide attempts were evaluated. Moreover, predictors of severe outcomes were evaluated. A total of 2,996 patients with self-inflicted injuries visited the three centers during a period of 3 yr. The male-to-female suicide ratio was 1:1.38 (P < 0.001). The mean age was 41 yr. Poisoning was the most common method of self-inflicted injury (68.7%) among all age groups. Medication was the primary means of injury in the < 50 age group, and the use of agricultural chemicals was the primary means in the > or = 50 age group. The reasons for attempting suicide varied among the age groups. The predictors of severe outcome are male gender, older age, and not having consumed alcohol.
