Importance: The COVID-19 pandemic disproportionately affected mental health in socioeconomically disadvantaged children in the US. However, little is known about the relationship of preexisting and time-varying social determinants of health (SDoH) at individual and structural levels, vaccination eligibility/rates, and the racial and ethnic differe...

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13-19 years; 53% female). A single-factor model with residual...

Full-text available
Purpose: Suicide rates are generally higher in men than in women. Men’s higher suicide mortality is often attributed to public-life adversities, like unemployment. Building on theory that men’s suicide vulnerability is also related to their private-life behaviors, particularly men’s low engagement in family carework, this ecological study explored...

PurposeThe risk of death from suicide after self-poisoning has been known to be significantly higher as compared to the general population. Nevertheless, the change in suicide risk before and after self-poisoning is still unclear.Methods The database of territory-wide medical records collected by the Hospital Authority of Hong Kong was used to iden...

Background/Purpose The outbreak of the Coronavirus disease 2019 (COVID-19) has led to unprecedented impact on mental health globally. Recent empirical data however, indicated that suicide rates in many countries remained unchanged or even decreased. Existing studies assessed the overall rates and did not stratify by age-subgroups. Methods We used...
Article
Background The global age-standardized suicide rate fell by 32.7% between 1990 and 2016. The decrease was largely due to suicide rate reductions in China and India. High-income Asian regions did not see such reductions. The aim of the current study was to explore recent suicide rate trends in Hong Kong and Taiwan to decompose which factors – age, p...
Article
The suicide rate in Hong Kong has increased significantly over the past four decades. Population subgroups such as the elderly or economically-distressed are reported to be more vulnerable than others to suicidal behaviors, while changing suicide methods (such as charcoal burning which emerged in 1998), has also contributed significantly to increas...

Background Several past studies indicated that religious beliefs, orientation, and practice are protective of suicide. Findings from recent studies in China suggest that religiosity may contribute to increased suicidality. However, few studies have examined the associations between religious affiliation across different faiths and suicidality in Ch...

Prognostic prediction is the task of estimating a patient's risk of disease development based on various predictors. Such prediction is important for healthcare practitioners and patients because it reduces preventable harm and costs. As such, a prognostic prediction model is preferred if: 1) it exhibits encouraging performance and 2) it can genera...
Article
Background: Self-stigma about suicide might impede people seeking help from mental health professionals. There is little research about self-stigma expressed by suicide decedents. Aims: We aimed to explore (a) self-stigma about suicide through examination of suicide notes; and (b) whether the expression of self-stigma was associated with the formal...
Article
Background Women’s suicide is a serious public health issue in low- and middle-income countries (LMIC). This study explored whether institutional discrimination against women, as manifested in formal and informal laws, is relevant to country’s income-level variability in women’s suicide mortality. It also examined which discriminatory laws are asso...

Design A retrospective follow-...
Chapter
The development of policy in Hong Kong may involve measures aimed at relieving the situation for those facing misfortune and dire circumstances, but it is also a question of addressing structural factors that lead to inequality, economic injustice and vulnerable circumstances. The former policy interventions involve social security measures and oth...
Chapter
Poverty and inequality in affluent societies involve structural and systemic issues that are manifested in the home, in neighbourhoods and in the workplace. Such domains often involve trade-offs, especially in a city such as Hong Kong where work commutes are often long, incurring time and money. This chapter considers many of the work and domestic...

Poverty is generally interpreted in either ‘absolute’ or ‘relative’ terms. Absolute poverty refers to a lack of resources to cover basic needs (including food, education, shelter, safe drinking water, healthcare, among other necessities). Relative poverty refers to an inability to access or afford reasonable standards of living experienced by other...

Chapter
In Hong Kong, the non-profit sector works closely with government to address gaps in social welfareWelfare delivery and deliver poverty alleviation efforts.

Chapter
Poverty is often thought of principally in terms of a deprivation of material possessions and means. However, a growing body of research recognizes the profound bidirectional relationships between relative poverty and health (physical and mental). A comprehensive poverty alleviation strategy must encompass a strong understanding of both the influen...
Chapter
As in every society, there are a number of subgroups in Hong Kong whose economic situation and quality of life do not necessarily improve in tandem with the rest of society, and whose voices are often absent from the public forum. To a certain extent, this could be said to be the case for the entire working poor. However, in this chapter we analyse...

Prior research suggests that most people perceive themselves to be more altruistic than the average population, an observation known as the better-than-average (BTA) effect. Understanding the BTA effect carries significant public health implications, as self-perceived altruism is closely related to altruistic behaviors, which plays a significant ro...
