RESUMO

AIMS: Restricting access to means by installing physical barriers has been shown to be the most effective intervention in preventing jumping suicides on bridges. However, little is known about the effectiveness of partial restriction with interventions that still allow jumping from the bridge. METHODS: This study used a quasi-experimental design. Public sites that met our inclusion criteria were identified using Google search and data on jumping suicides on Bridge A (South Korea), Bridges B and C (the United States) and Bridge D (Canada) were obtained from the relevant datasets. Incidence rate ratios (IRRs) were estimated using Poisson regressions comparing suicide numbers before and after the installation of physical structures at each site. RESULTS: Fences with sensor wires and spinning handrails installed above existing railings on the Bridge A, and fences at each side of the entrances and the midpoint of main suspension cables on the Bridge D were associated with significant reductions in suicides (IRR 0.37, 95% Confidence Interval (CI) 0.26 - 0.54; 0.26, 95% CI 0.09 - 0.76). Installation of bird spike on the parapet on the Bridge B, and fences at the front of seating alcoves on the Bridge C were not associated with changes in suicides (1.21, 95% CI 0.88 - 1.68; 1.49, 95% CI 0.56 - 3.98). CONCLUSIONS: Partial means restriction (such as fences with sensor wires and spinning bars at the top, and partial fencing at selected points) on bridges appears to be helpful in preventing suicide. Although these interventions are unlikely to be as effective as interventions that fully secure the bridge and completely prevent jumping, they might best be thought of as temporary solutions before more complete or permanent structures are implemented.

RESUMO

Background: Suicide rates have been increasing in Australia since the mid-2000s, especially for women aged ≤25 years. We conducted an age-period-cohort study to investigate these recent trends in the context of historical Australian suicide rates. Methods: Data on annual suicides in Australia from 1907 to 2020 were extracted from the General Record of Incidence of Mortality. We modelled age-specific effects for a reference cohort, after adjustment for period effects. Findings: We found evidence of age, cohort and period effects. For males, compared to the cohort born in 1946-1950, rates were higher for all cohorts born after this year. The period effect showed peaks in the risk of male suicide in the mid 1960s and the early 1990s, followed by a decline in risk until early 2010, after which the risk began to rise again. For females, compared to the cohort born in 1946-1950, the risk of suicide was higher for all cohorts born after this, with the highest risk for those born in 2006-2010. The period effect for females showed an elevated risk of suicide in the mid 1960s followed by a sharp decline, and an increase in risk after 2009. Interpretation: Suicide rates in Australia have fluctuated substantially over time and appear to be related to age trends as well as period and cohort trends. Advocacy and policy making tends to focus on contemporaneous changes in suicide rates. However, this study shows that focusing only on year-on-year changes in suicide rates ignores underlying trends for specific population birth-cohorts. Funding: None.

RESUMO

PURPOSE: To investigate whether two novel interventions on a bridge - a Video Incident Detection System (VIDS) and spinning bar barriers - have an impact on suicidal behaviour on the bridge. METHODS: A total of 146 suicidal acts were retrieved for analyses; 108 interventions before suicidal acts, 35 suicide deaths and 3 suicide attempts. Incident rate ratios (IRR) were calculated to estimate the change in incident rate associated with implementation of the two interventions: VIDS and the spinning bar 2-metre high barrier. RESULTS: The results of the Poisson regression showed that the rate of suicide deaths, after installation the VIDS, did not change significantly (IRR: 1.23, 95% Confidence Interval [95% CI]: 0.59-2.56), although the rate of intervened suicidal acts increased (IRR: 2.40, 95% CI: 1.65-3.47). The results showed that subsequent spinning bar installation resulted in a decrease in the incident rate of intervened suicidal acts (IRR: 0.37, 95% CI: 0.25-0.57) as well as suicide deaths (IRR: 0.23, 95% CI: 0.07-0.71). Comparison of the period when both interventions were in place with the period with no interventions indicated a reduction in suicide deaths (IRR: 0.28, 95% CI: 0.10-0.82), but no change in intervened suicidal acts (IRR: 0.90, 95% CI: 0.59-1.38). CONCLUSION: The rate of suicide death decreased after the installation of the spinning bar barrier but not after the implementation of VIDS alone. Our findings reinforce that restricting access to means is a highly effective way of preventing suicide on bridges and that spinning bars may be a helpful way to design barriers.

RESUMO

Background: Real-time suicide registers are being established in many countries and enable regular monitoring of suspected suicides over time. The use of these data to monitor for suicide clusters is in its infancy. Aims: We sought to test the feasibility of using real-time suicide register data to detect spatiotemporal suicide clusters. Method: Using the Victorian Suicide Register and SaTScan's spatiotemporal scan statistic, we simulated a monthly search for clusters from January 2015 to June 2022 using rolling 2-year windows of data in each search. Monthly scans were performed at three different levels of geographic granularity and for all-ages and under-25 populations. Results: Our results indicated the rapid identification of possible suicide clusters and demonstrated a practical approach to combining real-time suicide data and scanning algorithms. We developed new model outputs that showed cluster timelines. Limitations: The main limitations are that the computational burden of fitting multiple models meant we were unable to scan for ellipses and other irregular shapes and we were unable to consider space-time permutation models. Conclusions: Using data from a real-time suicide register, we were able to scan for space-time suicide clusters simulating the situation where the data are updated monthly with new updates.

RESUMO

Importance: Although several interventions have been shown to be effective in preventing suicide at high-risk locations, the potential for these interventions to be deployed is limited by a lack of knowledge about where high-risk locations are and the factors associated with choosing these locations. Objective: To identify high-risk suicide locations in Australia and the factors associated with choosing these locations. Design, Setting, and Participants: This case-control study included data on individuals who died by suicide in Australia between January 2001 and December 2017, obtained from the National Coronial Information System. Data analysis was conducted from February to December 2021. Exposures: Sociodemographic, residential, incident time, and incident location variables. Main Outcomes and Measures: The scan statistic was used to detect spatial clusters of suicides in public locations. Suicide locations within significant clusters with at least 0.5 suicides per year were defined as high-risk locations. Multivariable logistic regression analyses were performed to examine the factors associated with choosing a high-risk location. Results: Over the study period, 10 701 suicides took place in public places. The individuals who died of suicide in public places included 8602 (80.4%) male individuals, and most were aged 25 to 49 years (5825 [54.5%]). A total of 17 high-risk suicide locations in Australia were detected. These involved 495 suicides, which accounted for 4.6% of suicides in public locations. For suicides at high-risk locations, 82.2% (407 of 495) occurred at cliffs and bridges. Being female (adjusted odds ratio [aOR], 1.73; 95% CI, 1.41-2.13), employed (aOR, 1.57; 95% CI, 1.20-2.04), never married (aOR, 1.64; 95% CI, 1.26-2.13), and from a major city (aOR, 3.94; 95% CI, 2.94-5.28) were associated with the choice of a high- over low-risk suicide location. High-risk locations tended to be in major cities. Conclusions and Relevance: This case-control study found 17 high-risk suicide locations in Australia and the factors associated with the choice of these locations. Actions should be taken to prevent suicide at these locations where possible.

RESUMO

Workers' compensation systems aim to financially support injured workers. However, seeking compensation often leads to poorer physical and mental health outcomes. This review examines previous studies to investigate the relationship between workers' compensation and mental health and self-harm outcomes. A three-tiered search strategy across five databases identified studies that examined workers' compensation claims as an exposure or risk factor, with outcomes related to mental health, self-harm and suicidality. Nine full-text studies were included; however, heterogeneity limited generalizability. Most studies supported an association between pursuing compensation and poorer mental health and self-harm outcomes. Some studies attributed this to specific aspects of the system such as justice perception and navigation of the claims system. Findings suggest an association between workers' compensation and mental health or self-harm outcomes. Inconclusive findings highlight the need for further research. Understanding the psychiatric impacts of pursuing compensation is crucial to help formulate a more accessible compensation system.

RESUMO

Evaluations of interventions targeting the population level are an essential component of the policy development cycle. Pre-post designs are widespread in suicide prevention research but have several significant limitations. To inform future evaluations, our aim is to explore the three most frequently used approaches for assessing the association between population-level interventions or exposures and suicide - the pre-post design, the difference-in-difference design, and Poisson regression approaches. The pre-post design and the difference-in-difference design will only produce unbiased estimates of an association if there are no underlying time trends in the data and there is no additional confounding from other sources. Poisson regression approaches with covariates for time can control for underlying time trends as well as the effects of other confounding factors. Our recommendation is that the default position should be to model the effects of population-level interventions or exposures using regression methods that account for time effects. The other designs should be seen as fall-back positions when insufficient data are available to use methods that control for time effects.

RESUMO

Background: The Toronto Transit Commission (TTC) operates the public transit system in Toronto, Canada. From 1954 to 1980, there were 430 suicide deaths/attempts on the TTC subway system. In 2011, TTC implemented Crisis Link, a suicide helpline to connect subway passengers with counsellors. Upstream factors such as media reporting about suicide incidents may also influence suicidal behaviour. Our objectives were to investigate how Crisis Link and media reports about TTC suicide incidents influenced suicide rates. Methods: Suicide data were obtained from the TTC and Coroner, with Crisis Link data provided by Distress Centres of Greater Toronto (1998-2021). Media articles were identified through a database search of Toronto media publications. Interrupted time-series analysis investigated the association between Crisis Link calls, media articles, and quarterly suicide rates on the subway system. Findings: There were 302 suicides on TTC's subway system from 1998 to 2021. The introduction of Crisis Link was associated with a large but non-significant decrease in TTC-related suicide rate in the same quarter (IRR = 0.64, 95% CI = 0.36-1.12). Each subsequent post-Crisis-Link quarter experienced an average 2% increase in suicide rate (IRR = 1.02, 95% CI = 1.004-1.04). Furthermore, for each TTC-related media article in the previous quarter, the suicide rate on the TTC increased by 2% (IRR = 1.02, 95% CI = 1.004-1.04). Interpretation: The Crisis Link helpline was associated with a large but non-significant short-term decrease in suicide rates. However, this outcome was not sustained; this may, in part, be attributable to media reporting which was associated with increased suicides. This should inform suicide prevention policies in Canada and worldwide. Funding: No funding.

RESUMO

BACKGROUND: Hospital-treated self-harm is a strong predictor of suicide and hospital contacts may include missed opportunities for suicide prevention. We conducted a data linkage study to identify factors associated with suicide in people treated in hospital for self-harm in Victoria, Australia. METHOD: We undertook a cohort study following 14,307 people treated in hospital for an episode of self-harm (i.e., either admitted or non-admitted ED presentations) over the period 2011 and 2012 and used data from the Victorian Suicide Register to identify suicides within 5 years. We estimated unadjusted hazard ratios (HRs) for suicide using survival analysis for each exposure variable and then computed adjusted HRs using a multivariate model that included all exposure variables. RESULTS: Among females, the risk of suicide was higher in those aged 50-74 years (HR 1.78; Cl: 1.02, 3.10), residing in areas of least disadvantage (HR 2.58; Cl: 1.21, 5.50), who used hanging as a method of self-harm (HR 5.17; Cl: 1.86, 14.35) and with organic disorders (HR 6.71; Cl: 2.61, 17.23) or disorders of adult personality and behaviour (HR 2.10; Cl: 1.03, 4.27). In males, the risk of suicide was higher in those who used motor vehicle exhaust gas (MVEG) as a method of self-harm (HR 3.48; Cl: 1.73, 7.01), and with disorders due to psychoactive substance abuse (HR 1.75; Cl: 1.14, 2.67). CONCLUSION: Although all patients should be routinely assessed for risk and needs following hospital-treated self-harm including appropriate follow-up care, people who use MVEG or hanging as methods of self-harm are obvious candidates for close follow-up.

RESUMO

OBJECTIVE: This study investigated the relationship between work-related factors at baseline and the risk of common mental disorder at 12 month follow-up among a cohort of junior doctors. METHOD: The data comprised the junior doctor respondents from two annual waves of the 'Medicine in Australia: Balancing Employment and Life' (MABEL) survey, a national longitudinal cohort of Australian doctors. Individual and work-related risk factors were assessed at baseline and the mental health outcome of caseness of common mental disorder (CMD) was assessed using the 6-item Kessler Psychological Distress Scale at 12-month follow-up. Unadjusted and adjusted logistic regressions were conducted to estimate the association between each baseline variable and the likelihood of CMD caseness at follow-up 1 year later. RESULTS: Among 383 junior doctors, 24 (6%) had CMD 1 year later. Five work-related baseline variables were significantly associated with a higher likelihood of CMD 1 year later in adjusted models; lack of social support in work location (odds ratios (OR) = 6.11; 95% confidence intervals (CI) = [2.52, 14.81]), work-life imbalance (OR = 4.50; 95% CI = [1.31, 15.46]), poor peer support network in the workplace (OR = 2.61; 95% CI = [1.08, 6.27]), perceptions of patient expectations (OR = 2.46; 95% CI = [1.06, 5.71]) and total weekly work hours (OR 1.04; 95% CI = [1.01, 1.07]; p = 0.002)in models adjusting for gender. CONCLUSION: These results identify key modifiable work-related factors that are associated with junior doctors' future mental health. Our findings suggest the need for a greater focus upon interpersonal factors and work-life balance in multi-level interventions while continuing to address workplace and system-level factors to prevent future mental disorder in junior doctors.

RESUMO

BACKGROUND: Somatic Symptom Disorder is a psychiatric diagnosis that describes the experience of physical symptoms and associated distress, that is disproportionate to recognized organic pathology. Somatic symptom severity (SSS) may be associated with some surgical diagnoses; particularly the complex pain associated with pancreatitis, or the diagnostic ambiguity of undifferentiated abdominal pain (UAP). We aimed to estimate the prevalence of SSS in different diagnostic groups in surgical inpatients with abdominal pain; and to estimate the magnitude and direction of any association of SSS, anxiety and depression. METHODS: Cross sectional analysis (n = 465) of adult admissions with non-traumatic abdominal pain, at a tertiary hospital in Australia. We estimated SSS with the Patient Health Questionnaire-15 (PHQ-15), depression with the Patient Health Questionnaire (PHQ-9) and anxiety with the General Anxiety Disorder (GAD-7), at standard cut-points ≥ 10; comparing acute pancreatitis (n = 20), chronic pancreatitis (n = 18) and UAP (n = 64) versus other causes of abdominal pain. RESULTS: Somatic symptoms were common, 52% having moderate and 19.6% severe SSS. There was an association between moderate SSS and pancreatitis (OR 2.11, 95% CI 1.05-4.25) and depressive symptoms and chronic pancreatitis (OR = 3.47, 95% CI 1.31-9.24). There was no significant association between the four mental health categories and UAP. CONCLUSIONS: SSS and psychological comorbidity were common in a surgical inpatients admitted for abdominal pain and equally represented across most diagnostic sub-groups. However, the pancreatitis sub-group had greater proportions with clinically significant SSS and depression, suggesting that they have a higher requirement for psychological assessment and intervention.

RESUMO

Parental incarceration has been associated with educational disadvantages for children, such as lower educational attainment, increased grade retention, and truancy and suspensions. However, children exposed to parental incarceration often experience other adversities that are also associated with educational disadvantage; the contribution of these co-occurring adversities has not been considered in previous research. This study aimed to investigate the educational outcomes of children exposed to (a) maternal incarceration alone and (b) maternal incarceration plus other adversities (i.e., maternal mental illness and/or child protective services [CPS] contact). We used linked administrative data for a sample of children whose mothers were incarcerated during the children's childhood (i.e., from the time of mother's pregnancy through the child's 18th birthday; n = 3828) and a comparison group of children whose mothers had not been incarcerated (n = 9570). Multivariate multinomial logistic regressions examined the association between exposure to the three adversities (i.e., maternal incarceration, maternal mental illness, and child CPS contact) and above or below average reading and numeracy attainment in Grades 3, 5, 7 and 9. At all grade levels, children exposed to maternal incarceration alone and those exposed to maternal incarceration plus other adversities had increased odds of below average numeracy and reading attainment and decreased odds of above average numeracy and reading attainment compared to children without any of the recorded exposures. Children exposed to maternal incarceration and CPS contact and those exposed to all three adversities had increased odds of below average reading and numeracy attainment compared to children exposed to maternal incarceration alone. The findings highlight the complex needs of children of incarcerated mothers that must be considered when designing and delivering educational support programs. These children would benefit from the implementation of multi-tiered, trauma-informed educational and clinical services.

RESUMO

OBJECTIVE: Young adults with disabilities are less likely to be employed and more likely to have poor mental health than peers without disabilities. Growing evidence shows that social determinants of health may be causally related to mental health outcomes of people with disabilities. We aimed to assess if the disability to mental health association was mediated by employment status among young adults aged 20-35 years. METHODS: Four consecutive years (2016-2019) of data from the Household, Income and Labour Dynamics in Australia survey were used to conduct a causal mediation analysis. We decomposed the total causal effect of disability status on mental health (Short Form-36 Mental Health Inventory-5) into the natural direct effect from disability to mental health and the natural indirect effect representing the pathway through the employment mediator (being employed; being unemployed or wanting to work). RESULTS: 3435 participants (3058 with no disabilities, 377 with disabilities) were included in the analysis. The total causal effect of disability status on mental health was an estimated mean decrease in mental health of 4.84 points (95% CI -7.44 to -2.23). The indirect effect, through employment status, was estimated to be a 0.91-point decline in mental health (95% CI -1.50 to -0.31). CONCLUSIONS: Results suggest disability has an effect on the mental health of young adults; a proportion of this effect appears to operate through employment. The mental health of young adults with disabilities could potentially be improved with interventions to improve employment outcomes among this group, and by supporting individuals with disabilities into suitable employment.

RESUMO

BACKGROUND: Young people who have had contact with the criminal justice system are at increased risk of early death, especially from injuries. However, deaths due to non-communicable diseases (NCDs) in this population remain poorly described. We aimed to estimate mortality due to NCDs in people with a history of involvement with the youth justice system, compare NCD mortality rates in this population with those in the general population, and characterise demographic and justice-related factors associated with deaths caused by NCDs in people with a history of contact with the youth justice system. METHODS: In this retrospective, population-based cohort study (the Youth Justice Mortality [YJ-Mort] study), we included all people aged 10-18 years (at baseline) charged with a criminal offence in Queensland, Australia, between June 30, 1993, and July 1, 2014. We probabilistically linked youth justice records with adult correctional records and national death records up to Jan 31, 2017. Indigenous status was ascertained from youth justice and adult correctional records, with individuals identified as Indigenous in either source classified as Indigenous in the final dataset. We estimated crude mortality rates and standardised mortality ratios (SMRs) for comparisons with data from the Australian general population. We identified risk factors for NCD deaths using competing-risks regression. FINDINGS: Of 48 670 individuals aged 10-18 years (at baseline) charged with a criminal offence in Queensland, Australia, between June 30, 1993, and July 1, 2014, 11 897 (24·4%) individuals were female, 36 773 (75·6%) were male, and 13 250 (27·2%) were identified as identified as Indigenous. The median age at first contact with the youth justice system was 15 years (IQR 14-16), the median follow-up time was 13·4 years (8·4-18·4), and the median age at the end of the study was 28·6 years (23·6-33·6). Of 1431 deaths, 932 (65·1%) had a known and attributed cause, and 121 (13·0%) of these were caused by an NCD. The crude mortality rate from NCDs was 18·5 (95% CI 15·5-22·1) per 100 000 person-years among individuals with a history of involvement with the youth justice system, which was higher than among the age-matched and sex-matched Australian general population (SMR 1·67 [1·39-1·99]). Two or more admissions to adult custody (compared with none; adjusted sub-distribution hazard ratio 2·09 [1·36-3·22]), and up to 52 weeks in adult custody (compared with none; 1·98 [1·18-3·32]) was associated with NCD death. INTERPRETATION: Young people with a history of contact with the justice system are at increased risk of death from NCDs compared with age-matched and sex-matched peers in the general Australian population. Reducing youth incarceration and providing young people's rights to access clinical, preventive, and restorative services should be a priority.

RESUMO

OBJECTIVE: This study examined rates of suicide and hospitalization with psychiatric diagnoses after sleeve gastrectomy compared with gastric bypass and restrictive procedures (gastric banding/gastroplasty). METHODS: This was a longitudinal retrospective cohort study comprising all patients who underwent primary bariatric surgery in New South Wales or Queensland, Australia, between July 2001 and December 2020. Hospital admission records, death registration, and cause of death records (if applicable) within these dates were extracted and linked. Primary outcome was death by suicide. Secondary outcomes were admissions with self-harm; substance-use disorder, schizophrenia, mood, anxiety, behavioral, and personality disorders; any of these; and psychiatric inpatient admission. RESULTS: A total of 121,203 patients were included, with median follow-up of 4.5 years per patient. There were 77 suicides, with no evidence of difference in rates by surgery type (rates [95% CI] per 100,000 person years: 9.6 [5.0-18.4] restrictive, 10.8 [8.4-13.9] sleeve gastrectomy, 20.4 [9.7-42.8] gastric bypass; p = 0.18). Rates of admission with self-harm declined after restrictive and sleeve procedures. Admission with anxiety disorders, any psychiatric diagnosis, and as a psychiatric inpatient increased after sleeve gastrectomy and gastric bypass, but not restrictive procedures. Admissions with substance-use disorder increased after all surgery types. CONCLUSIONS: Variable associations between bariatric surgeries and hospitalization with psychiatric diagnoses might indicate distinct vulnerabilities among patient cohorts or that differing anatomical and/or functional changes may contribute to effects on mental health.

RESUMO

The 'nervous nineties' is a well-known cricket colloquialism that implies that batting within reach of 100 runs is mentally demanding. Despite common acceptance of this phenomenon, no study has used a historical test cricket dataset to examine how batting behaviour and performance changes on approach to a century. Accordingly, we explored opensource ball-by-ball data from 712 test cricket matches played between 2004 and 2022 to model the regression discontinuity of batting performance metrics either side of 100 runs. Models were fit using multi-level regression, adjusted for the clustering of balls within players (and where possible, the clustering of matches and innings within players). The analysis revealed that runs per ball and the probability of scoring a boundary increased as batters approached 100 runs. This was followed by a decline of -0.18 runs per ball (95% CI -0.22 to -0.14) and a three-percentage point decline (95% CI 2.2 to 3.8) in the probability of a boundary once a batter reached 100. The modelling revealed no evidence of a change in the probability of a dismissal before and after 100. Our results suggest many batters cope effectively with the psychological demands of playing through the nineties, including by batting aggressively and/or opportunistically to swiftly reach the milestone.

RESUMO

AIMS: Children of incarcerated mothers are at increased risk of experiencing multiple adversity such as poverty, mental illness and contact with child protection services (CPS), including being taken into out of home care (OOHC). However, little is known about whether these children are at increased risk of suicide or self-harm compared to children not exposed to maternal incarceration or about the factors that may contribute to this. We aimed to investigate differences in the risk of suicide and self-harm between children exposed to maternal incarceration and those not exposed and examine how socio-demographic factors, maternal mental illness and CPS contact (with or without OOHC) may affect these outcomes. METHODS: We used a retrospective matched cohort study design, comparing 7674 children exposed to maternal incarceration with 7674 non-exposed children. We used multivariable Cox proportional hazards regression to compare the risk of suicide and self-harm between exposed and non-exposed groups, controlling for geographical remoteness, CPS contact and maternal mental illness. RESULTS: There was no significant difference in the rate of suicide (rate ratio [RR] = 1.49; 95% confidence interval [CI]: 0.78, 2.87) or risk of suicide (adjusted hazard ratio [aHR] = 0.92; 95% CI: 0.43, 1.96) between the two groups. However, the exposed group had a significantly higher rate of self-harm (RR = 2.83; 95% CI: 2.50, 3.21) and a significantly higher risk of self-harm (aHR = 1.74; 95% CI: 1.45, 2.09) compared to those non-exposed. CPS contact with or without OOHC was independently associated with an increased risk of self-harm for both groups. CONCLUSION: Children exposed to maternal incarceration are at an increased risk of self-harm and should be prioritized to receive targeted, multimodal support that continues after the mother's release from prison. The association between CPS contact and self-harm warrants further research.

RESUMO

BACKGROUND: Health service utilisation changes across the life-course and may be influenced by contextual factors at different times. There is some evidence that men engage less with preventive health services, including attending doctors' clinics, however the extent to which this varies temporally and across different age groups is unclear. This study aimed to describe age or cohort effects on engagement with GPs among employed mothers and fathers in Australia, and differences in these trends between men and women. METHODS: We linked data from the 'Growing up in Australia: The Longitudinal Study of Australian Children' with administrative health service records from Medicare. We used a small-domain estimation Age-Period-Cohort method to describe patterns in health service use among working-age male and female parents in Australia while adjusting for employment status and controlling for time-invariant factors. Our small-domain method assumes a smooth response surface of Age, Period and Cohort. RESULTS: Male parents have lower health service engagement than women of the same age at the same time period. Men's pattern of health service use across time is likely explained entirely by ageing. That is, we find that patterns in health service utilisation among men are largely driven by age effects, with no evidence of periods or cohort effects in health service engagement for men between 2002 and 2016. CONCLUSIONS: Differences in health service utilisation between male and female parents at all age-period-cohort combinations highlight a need for more research to examine the extent to which this level of health service use among Australian men meets men's health needs, as well as barriers and enablers of health service engagement for men. Absence of evidence for period effects suggests that there is little shift in gendered patterns of health service utilisation during the observed period.
