Unemployment and suicide. Evidence for a causal association

Objectives: To determine the independent associations of labour force status and socioeconomic position with death by suicide. Design: Cohort study assembled by anonymous and probabilistic record linkage of census and mortality records. Participants: 2.04 million respondents to the New Zealand 1991 census aged 18–64 years. Main outcome measure: Suicide in the three years after census night. Results: The age adjusted odds ratios (95% confidence intervals) of death by suicide among 25 to 64 year olds who were unemployed compared with employed were 2.46 (1.10 to 5.49) for women and 2.63 (1.87 to 3.70) for men. Similarly increased odds ratios were observed for the non-active labour force compared with the employed. Strong age only adjusted associations of suicide death with the socioeconomic factors of education (men only), car access, and household income were observed. Compared with those who were married on census night, the non-married had odds ratios of suicide of 1.81 (1.22 to 2.69) for women and 2.08 (1.66 to 2.61) for men. In a multivariable model the association of socioeconomic factors with suicide reduced to the null. However, marital status and labour force status remained strong predictors of suicide death. Unemployment was also strongly associated with suicide death among 18–24 year old men. Sensitivity analyses suggested that confounding by mental illness might explain about half, but not all, of the association between unemployment and suicide. Conclusions: Being unemployed was associated with a twofold to threefold increased relative risk of death by suicide, compared with being employed. About half of this association might be attributable to confounding by mental illness.

The association of food security with psychological distress in New Zealand and any gender differences

Food security (access to safe, nutritious, affordable food) is intrinsically linked to feelings of stress or distress and it is strongly associated with socioeconomic factors. However, the impact of food insecurity on mental health, independent of confounding socioeconomic factors, is not clear. We investigated the association of food insecurity with psychological distress in New Zealand, controlling for socioeconomic factors. Secondarily, we examined the association in males and females. We used data from the Survey of Families, Income and Employment (SoFIE) (N = 18,955). Respondents were classified as food insecure if, in the last 12 months, they: used special food grants/banks, had to buy cheaper food to pay for other things, or went without fresh fruit and vegetables often. Psychological distress was measured using the Kessler-10 scale dichotomised at low (10-15) and moderate to high (16+). Logistic regression analyses were used to investigate the association of food insecurity with psychological distress using a staged modelling approach. Interaction models included an interaction between food security and gender, as well as interactions between gender and all other covariates (significant at p-value < 0.1). Models were repeated, stratified by gender. A strong relationship between food insecurity and psychological distress was found (crude odds ratio OR 3.4). Whilst substantially reduced, the association remained after adjusting for confounding demographic and socioeconomic variables (adjusted OR 1.8). In stratified models, food insecure females had slightly higher odds for psychological distress (fully adjusted OR 2.0) than males (fully adjusted OR 1.5). As such, an independent association of food insecurity with psychological distress was found in both males and females--slightly more so in females. However, we cannot rule out residual confounding as an explanation for the independent association and any apparent gender interaction.

Learning to Be Leaders in Higher Education: What Helps or Hinders Women’s Advancement as Leaders in Universities:

This article examines 110 reported incidents from an online survey of 26 women from each of the eight universities in New Zealand. They responded to questions asking them to describe times when work and non-work situations have helped or hindered their advancement in university leadership roles. Five key themes, incorporating a range of factors, emerged as making a difference to advancement as leaders. These themes are: work relationships; university environment; invisible rules; proactivity; and personal circumstances. This research is part of the L-SHIP (Leadership- Supporting Higher Intent & Practice) project and has two main aims. First, to identify factors in universities that help and hinder women’s advancement as leaders, as reported by women; second, to provide useful evidence to underpin the development of programmes supporting women’s advancement in university leadership roles. This research is a first step in the development of the L-SHIP Toolkit for good practice in leadership development in higher education.

When does neighbourhood matter? Multilevel relationships between neighbourhood social fragmentation and mental health

Studies investigating relationships between mental health and residential areas suggest that certain characteristics of neighbourhood environments matter. After developing a conceptual model of neighbourhood social fragmentation and health we examine this relationship (using the New Zealand Index of Neighbourhood Social Fragmentation (NeighFrag)) with self-reported mental health (using SF-36). We used the nationally representative 2002/3 New Zealand Health Survey dataset of urban adults, employing multilevel methods. Results suggest that increasing neighbourhood-level social fragmentation is associated with poorer mental health, when simultaneously accounting for individual-level confounding factors and neighbourhood-level deprivation. The association was modified by sex (stronger association seen for women) and labour force status (unemployed women more sensitive to NeighFrag than those employed or not in labour force). There was limited evidence of any association of fragmentation with non-mental health outcomes, suggesting specificity for mental health. Social fragmentation as a property of neighbourhoods appears to have a specific association with mental health among women, and particularly unemployed women, in our study.

What is the association between wealth and mental health

Background: Socioeconomic inequalities in mental health have been shown in a number of populations. This study aims to investigate the association between asset wealth and psychological distress in New Zealand and whether it is independent of other socioeconomic measures and baseline health status. Methods: Data for this study were from the first three waves of the Survey of Families, Income and Employment (SoFIE) conducted in New Zealand (2002–2004/05) (n = 15 340). The Kessler-10 was used as a measure of psychological distress. The association of quintiles of wealth with psychological distress was investigated using logistic regression, controlling for confounders, socioeconomic variables and prior health status. Results: The odds ratio (OR) of reporting high psychological distress were greater in the lowest wealth quintile compared with the highest (OR 3.06, 95% CI 2.68 to 3.50). Adjusting for age and sex did not alter the relationship; however, adjusting for income and area deprivation attenuated the OR to 1.73 (95% CI 1.48 to 2.04). Further controlling for baseline health status reduced the OR to 1.45 (95% CI 1.23 to 1.71), although the confidence interval still excluded the null. Conclusions: Inequalities in wealth are strongly associated with psychological distress, over and above other confounding demographic variables and baseline health status. Much, but not all, of that association is confounded by adult socioeconomic position. This suggests that policy measures to improve asset wealth, through savings and home ownership, may have positive health implications and help to reduce health inequalities.

Sex-specific impact of socio-economic factors on suicide risk: a population-based case–control study in Denmark

BACKGROUND Although many authors have investigated the impact of sex on the association between socio-economic status (SES) and suicide, a definite consensus has not yet emerged. Using Danish population registration data including 15 648 suicide deaths of individuals aged 18-65 year during 1981-97 and matched population controls, we investigate the associations of multiple SES factors with suicide risk and explore the sex-specific aspects of these associations. METHODS We use conditional logistic regression models to estimate the statistical relationship between SES, sex and suicide. RESULTS SES, proxied by low income, unskilled blue-collar work, non-specific wage work and unemployment, increases suicide risk more prominently for men than for women. Marital status has a comparable influence on suicide risk in both sexes; parenthood is protective against suicide, and the effect is larger for women. Living in a large city raises suicide risk for women but reduces it for men; residents with a foreign citizenship in Denmark have a lower risk of suicide compared with Danish citizens, but this protection is confined to male immigrants. CONCLUSIONS Our results demonstrate that suicide risk is associated with a range of SES proxies but the strength and/or direction of the association can differ by sex. Risk assessment and, therefore, prevention approaches should take this into consideration.

Death knocks, professional practice, and the public good: The media experience of suicide reporting in New Zealand

Health, government, and media organizations around the world have responded to research demonstrating the imitative effects of suicide coverage in the news media by developing guidelines to foster responsible reporting. Implementation of these guidelines has encountered some resistance, and little is known about the media perspective on suicide coverage and its effects on guideline use. This qualitative study provides an in-depth appreciation of this perspective by investigating the experiences of journalists covering suicide in New Zealand. Fifteen newspaper, television and radio journalists were interviewed between December 2008 and March 2009 and transcripts were analyzed using a grounded hermeneutic editing approach. Five themes were identified: public responsibility, media framing of suicide, professional practice, personal experience of suicide reporting, and restricted reporting. Participants asserted the role of the media in the protection of the public good. Though this stance aligns them with the goals of health policymakers, it is derived from a set of professional mores at odds with the perceived paternalism of suicide reporting guidelines. Participants were stakeholders in the issue of suicide coverage. We conclude that policymakers must engage with the news media and acknowledge the competing imperatives that provide the context for the application of suicide reporting guidelines by individual journalists. Collaborative guideline development will be vital to effective implementation.

How much do mental disorders contribute to New Zealand’s tobacco epidemic?

Objective: To quantify the share of tobacco consumed by people with 12-month mental disorders in New Zealand. Methods: Estimates of current smoking prevalence and the 12-month prevalence of three groups of mental disorders—anxiety, mood and substance use disorders—were derived from the New Zealand Mental Health Survey, a nationally representative survey of almost 13 000 adults (16+ years) fielded in 2003–4. Estimates of the smoking intensity ratio (comparing smokers with mental disorders to those without mental disorders) were derived from the 2006–7 New Zealand Health Survey. Results: Approximately 33% of all cigarettes are consumed by people with 12-month mental disorders (males 27%, females 39%), using an estimated smoking intensity ratio of 1.21. Among this group, anxiety disorders account for almost one-half of consumption, mood disorders for over one-quarter and substance use disorders for about one-fifth. Conclusion: This study quantifies for the first time the contribution of mental disorders to tobacco consumption in New Zealand. In particular, it identifies anxiety disorders as an important risk factor for tobacco use. People with mental disorders are an important target group for tobacco control. Enhanced collaboration and sharing of expertise between smoking cessation service providers and community mental health services are urgently needed.

The WHO START study: suicidal behaviors across different areas of the world.

BACKGROUND The World Health Organization (WHO) study entitled Suicide Trends in At-Risk Territories (START) is an international multisite initiative that aims to stimulate suicide research and prevention across different areas of the globe. A central component of the study is the development of registration systems for fatal and nonfatal suicidal behaviors. AIMS This paper provides an overview of the data collected on suicidal behaviors from the participating locations in the START study. METHOD Descriptive statistics on the data are presented in terms of age, sex, and method. RESULTS A greater proportion of suicide deaths occurred among males. In all areas except the Philippines more females than males engaged in nonfatal suicidal behaviors. Compared to Australia, Italy, New Zealand, the Philippines, and Hong Kong SAR, in the Pacific Islands suicide most often occurs in younger age groups. Results indicate notable variations between countries in choice of method. A greater proportion of suicides occurred by hanging in Pacific Islands, while inhalation of carbon monoxide, use of firearms, ingestion of chemicals and poisons, and drug overdose were the most frequent methods of choice in other areas. CONCLUSION The information drawn from this study demonstrates the enormous variation in suicidal behavior across the areas involved in the START Study. Further research is needed to assess the reliability of the established data-recording systems for suicidal behaviors. The baseline data established in START may allow the development of suicide prevention initiatives sensitive to variation in the profile of suicide across different locations.

Survey of drug and alcohol use by lesbian women in new zealand

The objective of this study is to describe the prevalence of alcohol and drug use and attitudes towards alcohol use in a group of New Zealand lesbian women. The method used is 1,222 copies of a postal questionnaire (the Lesbian Mental Health Survey [LMHS]) were distributed via lesbian newsletters over a 4-month period. Responses were received from 561 women, an estimated response rate of 50.8%. The respondents were predominantly New Zealand European, highly educated, urban women in the 25- to 50-year age bracket; 30.1% smoked cigarettes, and 90.2% had drunk alcohol at some time in the past year, over half once per week or less. The median number of drinks per week was 1.5 drinks, equivalent to 22.5 ml alcohol per week. Despite a comparatively low reported use of alcohol, 48.1% of respondents expressed the view that alcohol is used excessively in the lesbian community; 75.8% had used cannabis at least once, 32.6% in the past year; 30.8% had used recreational drugs other than cannabis and alcohol at some time, 4.5% in the past year.
