Focused ultrasounds: What is their future in epileptology? A critical review

High intensity focused ultrasounds (HIFU) are being increasingly advocated as a useful tool in the management of focal drug-resistant epilepsy. Our aim was to review current literature on the topic and perform an inventory of open trials assessing HIFU effectiveness and safety in epilepsy management. To do so, a review was conducted and yielded one prospective clinical trials, two case reports and one safety study were retrieved, indicating that HIFU is still in its infancy when it comes to focal drug-resistant epilepsy therapy. Efforts should be made to develop this technology using multicentric prospective data with larger cohorts and prolonged follow-up.

"Friend-ish": Home Care Workers, "Social Labor" and Managing the Boundaries of the Carer Relationship

We examine how changes in home care work, with greater emphasis on social support, have led to corresponding changes in the forms of labor performed by home care workers. Drawing on interviews with fifty older adults, we find in addition to physical and emotional labor, workers may be increasingly expected to engage in a form of labor we term "social labor," in which they actively manage the boundary between the professional services they provide and the personal relationships that may develop. We find examples of such expectations include (1) following the lead of clients who set out terms of the relationship and degree of sociality, (2) managing the potential dual role of "support worker" and "friend," and (3) meeting social needs of clients vulnerable to isolation. As Government acknowledges the value of social support and companionship, greater attention is needed to this aspect of care work, with implications for workers and clients.

Diversity of strong and weak ties and loneliness in older adults

This paper examines the relationship between characteristics of older adults' networks and loneliness. Drawing on a mixed-methods study with primary data from 165 surveys and a subset of 50 in-depth interviews from the broader sample, we examine whether and how strong and weak ties in an individual's network provide different forms of support in buffering loneliness. Regression models demonstrate that a higher frequency of contacts with strong ties, rather than the number of strong ties, is associated with lower levels of loneliness. In contrast, a greater number of weak ties is related to lower levels of loneliness. Our qualitative interview data shows that strong ties are susceptible to relationship loss, geographic distances, or relationship conflict. A greater number of weak ties, on the other hand, increases the likelihood of support and engagement when needed, reciprocity of relationships, and access to new social groups and networks. Previous research has focused on the complementary forms of support provided by strong and weak ties. Our study shows the different forms of support provided by strong and weak ties, underscoring the importance of a diverse social network for reducing loneliness. Our study also highlights the role of network changes in later life and social tie availability as important factors that contribute to understanding how social ties operate to combat loneliness.

Search for Gamma-Ray Spectral Lines from Dark Matter Annihilation up to 100 TeV toward the Galactic Center with MAGIC

Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σv⟩≲5×10^{-28}  cm^{3} s^{-1} at 1 TeV and ⟨σv⟩≲1×10^{-25}  cm^{3} s^{-1} at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.

Geographical variations in the prevalence of traditional and cyberbullying and its additive role in psychological and somatic health complaints among adolescents in 38 European countries

OBJECTIVES

To explore geographical variations in the prevalence of traditional and cyberbullying and their individual and additive role on psychological and somatic health issues of adolescents.

METHODS

We used cross-sectional data from 188,003 adolescents (50.9% females; mean age 13.6 years) from the nationally representative Health Behaviour in School-aged Children 2014 survey in 38 European countries. Multivariable linear regression analyses were conducted to explore the role of bullying on health outcomes whilst meta-analyses were conducted to generate pooled regression coefficients.

RESULTS

Overall, the prevalence of traditional bullying was 26.9%, ranges from 8.8% in Armenia to 49.7% in Latvia, and cyberbullying was 15.8%, ranges from 5.8% in Greece to 38.3% in Greenland. 1 in 10 (8.4%) adolescents reported experiencing both forms of bullying, with the prevalence ranging from 2.5% (Greece) to 21.0% (Greenland). Meta-analytic estimates suggest a significant role of both traditional and cyberbullying in poor somatic and psychological health issues. The additive effect of both forms of bullying was more prominent on psychological health issues (β 0.70, 95% CI 0.66-0.74) than on somatic health issues (β 0.50, 95% CI 0.47-0.53). These associations varied across countries.

CONCLUSION

The prevalence of traditional and cyberbullying varied significantly across European countries while their individual and additive links with an increased risk of poor psychological and somatic health issues remain common in majority countries. To ensure both forms of bullying are prevented, a multifaceted approach and particular attention to mental health issues in bullying victims are needed in countries with high prevalence of bullying.

Sexual Fluidity and Psychological Distress: What Happens When Young Women's Sexual Identities Change?

The sexual identities of young women today are less binary and more fluid than ever before. Several theoretical perspectives imply that this fluidity could be accompanied by distress. To examine this, we analyzed four waves of data from Australian women born 1989 to 1995 (n = 11,527). We found no evidence of a universal association between sexual identity change and psychological distress. Instead, psychological distress was elevated when women changed their identity away from the heterosexual norm and lowered when they changed their identity toward it. Social stress partly attenuated these associations. In addition, women unsure of their identity at multiple assessment points reported significantly greater psychological distress in the final assessment than women who were never unsure. Our findings suggest that greater support should be offered to women who are questioning their sexual identity or developing a minority identity.

Variation in the prevalence of different forms of bullying victimisation among adolescents and their associations with family, peer and school connectedness: a population-based study in 40 lower and middle income to high-income countries (LMIC-HICs)

This study aimed to estimate the prevalence of different forms of bullying victimization experiences and their association with family functioning, peer relationships and school connectedness among adolescents across 40 lower and middle income to high-income countries (LMIC-HICs). Data were drawn from the Health Behaviour in School-Aged Children (HBSC) school-based survey of adolescents aged 11-15 years, between 2013 and 2014. We estimated the weighted prevalence by categorising experiences into traditional bullying victimization only, cyberbullying victimization only, and combined traditional and cyberbullying victimization, at country and country income classification. We used multinominal logistic regression models to estimate the adjusted association with the form of bullying victimization by demographic characteristics, family functioning, peer relationships and school connectedness. Overall, 8.0% reported traditional bullying victimization only (8.8% males, 7.4% females), 2.3% of adolescents reported cyberbullying victimization only (2.1% males, 2.2% females), and 1.7% reported combined traditional and cyber bullying victimization (1.7% males, 1.8% females). All three forms of bullying victimization during adolescence were significantly associated with poor family functioning, poor peer relations and poor school connectedness. A consistent finding is that traditional bullying victimization is considerably more common among adolescents across both LMICs and HICs than cyberbullying victimization. This study also demonstrated that a significant proportion of adolescent's experience victimization in both forms. Positive family functioning, strong peer relationships and greater school connectedness are associated with a lower risk of both forms of bullying victimization.

Prevalence of multiple non-communicable diseases risk factors among adolescents in 140 countries: A population-based study

BACKGROUND

Modifiable non-communicable disease (NCD) risk factors are becoming increasingly common among adolescents, with clustering of these risk factors in individuals of particular concern. The aim of this study was to assess global status of clustering of common modifiable NCD risk factors among adolescents.

METHODS

We used latest available data from nationally representative survey for 140 countries, namely the Global School-based Student Health Survey, the Health Behaviour in School-Aged Children and the longitudinal study of Australian Children. Weighted mean estimates of prevalence with corresponding 95% confidence intervals of nine NCD risk factors - physical inactivity, sedentary behaviour, insufficient fruits and vegetable consumption, carbonated soft drink consumption, fast food consumption, tobacco use, alcohol consumption and overweight/obesity - were calculated by country, region and sex.

FINDINGS

Over 487,565 adolescents, aged 11-17 years, were included in this study. According to trend analysis, prevalence of four or more NCD risk factors increased gradually over time. Prevalence of four or more NCD risk factors was 14.8% in 2003-2007 and increased to 44% in 2013-2017, an approximately three-fold increase (44.0%). Similar trends were also observed for three and two risk factors. Large variation between countries in the prevalence of adolescents with four or more risk factors was found in all regions. The country level range was higher in the South-East Asia Region (minimum Sri Lanka = 8%, maximum Myanmar = 84%) than Western Pacific Region (minimum China = 3%, maximum Niue = 72%), European Region (minimum Sweden = 13.9%, maximum Ireland = 66.0%), African Region (minimum Senegal = 0.8%, maximum Uganda = 82.1%) and Eastern Mediterranean Region (minimum Libya = 0.2%, maximum Lebanon = 80.2%). Insufficient vegetable consumption, insufficient fruit consumption and physically inactivity were three of the four most prevalent risk factors in all regions.

INTERPRETATION

Our results suggest a high prevalence of four or more NCD risk factors in adolescents globally, although variation was found between countries. Results from our study indicate that efforts to reduce adolescent NCD risk factors and the associated health burden need to be improved. These findings can assist policy makers to target the rollout of country- specific interventions.

Do extracurricular activities contribute to better adolescent outcomes? A fixed-effects panel data approach

INTRODUCTION

Extracurricular activity participation is associated with positive academic, health, and behavioral outcomes for adolescents, but these findings may reflect unobserved confounding rather than participation effects.

METHOD

Data were drawn from 3885 adolescents aged 12-15 in a nationally representative cohort of Australian adolescents. Effects of participation in three kinds of extracurricular activity (team sport, individual sport, and arts) on an array of outcomes were modeled using fixed-effects regression to account for potential unobserved confounding.

RESULTS

Strong bivariate relationships between all forms of activity participation and positive adolescent outcomes were found. These associations were much smaller in the fixed-effects analysis, but beneficial effects of sports for mental health and arts for peer group characteristics remained statistically significant. Minimal effects of extracurricular activity participation for academic achievement were found.

CONCLUSION

Extracurricular activity participation has beneficial effects on adolescents' mental health and exposure to peers' delinquent behavior.

Transformation, disruption or cumulative disadvantage? Labor market and education trajectories of young mothers in Australia

Young motherhood is often framed as detrimental to the life chances of young women with research showing negative impacts on education and labor market outcomes. At the same time, qualitative research reports narratives of motherhood as a transformative experience, providing motivation for a fresh start and moving young women away from previously unstable life pathways. These scenarios appear contradictory, however outcomes might vary for different groups of women depending on their pre-birth trajectories. We investigate the effects of early parenthood using the Household, Income and Labour Dynamics in Australia (HILDA) survey. We employ a sequence based approach to compare labor market- and educational precarity of young mothers and non-parenting peers. We employ a novel sequence matching technique creating a comparison group of non-parenting young women, based on similarities in early labor market trajectories. We find that young mothers have higher levels of precarity in their pre-birth trajectories. Moreover, our results show that becoming a young mother is connected to an average increase in labor market and educational precarity post birth, which supports the hypothesis of cumulative disadvantage. However, only mothers with the least precarious trajectories prior to birth experience this development, whereas young women already on highly precarious paths see a decrease in precarity over time. Although our results do not support cumulative disadvantage for the most disadvantaged women, neither does it support the idea of parenthood as a transformative event. Our results point to the importance of understanding heterogeneity in the outcomes of young mothers.

Not in employment, education or training (NEET); more than a youth policy issue

Introduction

Australians who are Not in Employment, Education or Training (NEET) and receive income support span a wide spectrum of working ages. Australian research has concentrated on NEETs aged 15–29 years, in line with international standards. This paper investigates extending the NEET concept to include all working age persons 15–64 years and the value added to welfare policy through analysis of a new linked dataset.

Methods

An observational study design was implemented with individuals aged 15-64 years recorded as receiving Department of Social Services (DSS) income support payments from September 2011 being linked with Australian Bureau of Statistics (ABS) Census data from August 2011 to create a linked dataset for analysis. Descriptive analyses were undertaken of NEET status by Census socio-demographic characteristics, and we modelled the adjusted likelihood of NEET status by Census demographics.

Results

Some 1.37 million or 45.2% of linked DSS payment recipients qualified as NEET. Of NEETs, more than twice as many were female, nearly half were aged 45–64 years, and under 1-in-5 were aged 15–29 years. Multivariate analyses showed that NEETs were more likely to be older, have low educational attainment, have a disability, and to be Indigenous.

Conclusions

Young NEETs aged 15–29 years represented less than 20% of linked DSS payment recipients classified as NEET, suggesting that standard NEETs reporting neglects information on around 80% of the working age NEET population in Australia. Combined with other demographic insights, these results have implications for welfare policy, and indicate a wider range of demographics should be considered under the NEET classification. This may also have implications for Organisation for Economic Co-operation and Development (OECD) reporting.

Mothers, fathers and the intergenerational transmission of gender ideology

Traditional gender beliefs play an important role in (re-)producing gender inequalities, and trends towards gender egalitarianism have stalled. As such, identifying factors that contribute to individuals upholding traditional versus egalitarian gender attitudes is an important scholarly endeavour. While previous studies have identified critical predictors-such as religion, education and parenthood-intergenerational influences have received comparatively little empirical attention. Drawing upon gender-socialization theory, we derive hypotheses about how parental attitudes towards gender are transmitted to their children, considering differences between mothers' and fathers' influences, parental (dis)agreement in attitudes, and moderation by child's gender. We test these hypotheses using high-quality data from a national sample of Australian 14/15-year-old adolescents (Longitudinal Study of Australian Children, n = 1806). We find substantial intergenerational associations in gender ideology. Paternal and maternal attitudes exert a similar degree of influence on their children's attitudes, and have complementary rather than cumulative effects. While fathers' attitudes influence sons' and daughters' attitudes equally, mothers' attitudes influence daughters' attitudes more than sons'.

Pathways linking bullying victimisation and suicidal behaviours among adolescents

AIMS

To examine the pathways explaining the association between bullying victimisation and suicidal behaviours among school-based adolescents.

METHODS

We used data from the Global School-based Student Health Survey from 90 countries conducted between 2003 and 2017. We applied multivariate regression and generalised structural equation models to examine the pathways.

RESULTS

Of 280,076 study adolescents, 32.4% experienced bullying and 12.1%, 11.1% and 10.9% reported suicidal ideation, suicidal planning and suicidal attempt, respectively. Adolescents who experienced bullying had higher rates of hunger (8.7% vs 5.0%), drinking soft drinks (44.0% vs 40.2%), truancy (35.8% vs 22.7%), smoking (14.0% vs 6.9%), alcohol consumption (19.9% vs 11.8%), peer victimisation (54.0% vs 25.6%), peer conflict (47.4% vs 20.1%), sleep disturbance (13.7% vs 5.6%), loneliness (18.1% vs 7.6%), no close friends (7.5% vs 5.2%), lack of peer support (64.9% vs 53.3%), lack of parental connectedness (67.0% vs 60.4%) and less parental bonding (64.1% vs 55.2%). Nearly one-fourth (18.7%) of the total association between bullying and suicidal ideation was mediated by loneliness. Similarly, sleep disturbances and alcohol consumption also mediated 4 to 9% of the association between bullying and suicidal behaviours.

CONCLUSION

This study suggests targeted policies and early implementation of interventional strategies focusing on addressing loneliness, sleep disturbance and alcohol consumption to reduce the risk of adverse suicidal behaviours among adolescents.

Changes in Sexual Identity Labels in a Contemporary Cohort of Emerging Adult Women: Patterns, Prevalence and a Typology

Sexual attraction, behavior and identity are subject to change across the life course for some individuals, and certain developmental periods such as emerging adulthood appear particularly conducive to this. However, the evidence documenting these phenomena comes overwhelmingly from data collected 10-20 years ago. In the brief interlude since, the socio-political context has changed markedly and increasing numbers of women are reporting non-heterosexuality. Drawing on contemporary data from the Australian Longitudinal Study on Women's Health (n = 16,870), we provide up to date evidence on changes in sexual identity labels among emerging adult women. We found that 19% of women changed their sexual identity label from one survey wave to the next, and 30.6% changed their identity label at least once across the four waves. Mostly heterosexual and bisexual labels were both more common and more stable in our sample than in previous studies. We propose a new typology of sexual identity sequences and fit this to our data, providing a blueprint for researchers looking to define sexual minority status longitudinally. Findings suggest that the ways women perceive and label their sexual orientation should be treated as dynamic phenomena situated within the nested temporalities of biographical and historical time.

Comparative effectiveness of antiretroviral drug classes for the treatment of HIV infection in patients with high viral loads: a multicentre retrospective cohort study

OBJECTIVES

We aimed to compare the effectiveness of antiretroviral therapy (ART) classes for achieving HIV RNA suppression to < 50 HIV-1 RNA copies/mL within 6 months of initiation with high viral loads (VLs). Secondary objectives were to compare viral suppression (VS) at 12 weeks and 12 months, partial HIV RNA suppression to < 200 copies/mL, time to VS, time to rebound, and change in CD4 cell count.

METHODS

This was a multicentre, retrospective, observational study. Adult patients were included if they initiated ART between January 2005 and December 2016 with a VL ≥ 100 000 copies/mL.

RESULTS

There were 220 patients included in the study. The median VL was 252 919 [interquartile range (IQR) 149 472-500 000] copies/mL. Nonnucleoside reverse transcriptase inhibitor (NNRTI) recipients were more likely to achieve VS by 6 months compared to those initiating ART containing protease inhibitors (PIs) [75.4% vs. 44.1%, respectively; odds ratio (OR) 3.34; 95% confidence interval (CI) 1.62-6.90] or integrase strand transfer inhibitors (INSTIs) (75.4% vs. 55.8%, respectively; OR 2.40; 95% CI 1.03-5.58). VS at 12 weeks was more frequent with INSTI-containing regimens than with PIs (28.9% vs. 9.0%, respectively; OR 4.10; 95% CI 1.69-9.92). VS at 12 months did not significantly differ between treatment regimens. Median time to complete VS for INSTI, PI and NNRTI recipients was 22.3 (95% CI 13.4-33), 30.1 (95% CI 25-36) and 19.9 (95% CI 16-22.3) weeks, respectively. There were no significant differences in time to viral rebound or change in CD4 cell counts.

CONCLUSIONS

Patients with high VLs initiated on NNRTIs were more likely to achieve VS by 6 months on ART compared to INSTI and PI recipients.

Chronic conditions, couple-level factors and union dissolution

This paper examines the association between chronic illness and union dissolution by examining rich, longitudinal data from the Household, Income and Labour Dynamics in Australia (HILDA) survey. Using competing-risks discrete-time event-history models on longitudinal, dyadic data, we find the risk of union dissolution to be approximately 40 percent higher when either partner reports an illness than in the absence of an illness. We then examine whether the observed associations are mediated by variations in paid work, housework, financial stress and time stress. Financial stress is the factor that contributes most to the indirect associations between dissolution and partner's health condition, but overall these factors account for only 18.5 percent of the association between chronic illness and relationship dissolution. Our results provide further insight into the factors undermining relationship stability and highlight the importance of reducing financial stress associated with chronic illness.

Sexual Minority Women in Longitudinal Survey Research: Is Attrition a Problem?

As more longitudinal surveys collect information on sexual orientation, evaluating the quality of these data and understanding how sexual minorities engage with the survey process are increasingly important endeavors. This study constitutes the first systematic analysis of sexual orientation as a predictor of attrition from longitudinal surveys. Drawing upon the minority stress model, we developed testable hypotheses about how sexual identity and sexual identity change relate to panel attrition. These hypotheses were subsequently tested using data from two national cohorts of Australian women from the Australian Longitudinal Study on Women's Health (one born 1973-1978, n = 11,262, and one born 1989-1995, n = 16,689). In the older cohort, sexual minority women were more likely to attrit from the survey than exclusively heterosexual women-largely due to noncontact rather than noncooperation. The associations faded once sociodemographic and health-related covariates were included in the models. Further, higher rates of noncontact were observed among women who changed their sexual identity in a more same-sex-oriented direction, compared to women with a stable sexual identity. None of these associations were apparent in the younger cohort. Taken together, our results suggest that sexual minority status may be a risk factor for panel attrition among older but not younger cohorts of women and that improved efforts to locate and contact participants who are generally vulnerable could increase the retention of sexual minorities in longitudinal studies. Effect sizes were nevertheless small, suggesting that existing research on sexual orientation using longitudinal surveys is unlikely to be biased by non-random attrition of non-heterosexual individuals.

Global variation in the prevalence of suicidal ideation, anxiety and their correlates among adolescents: A population based study of 82 countries

BACKGROUND

Suicidal ideation and anxiety are common among adolescents although their prevalence has predominantly been studied in high income countries. This study estimated the population prevalence of suicidal ideation and anxiety and their correlates with peer support, parent-adolescent relationship, peer victimization, conflict, isolation and loneliness across a range of low-income, lower-middle-income, upper-middle-income countries and high-income countries (LMIC-HICs).

METHODS

Data were drawn from the Global School-based Student Health Survey (GSHS) of adolescents aged 12-17 years between 2003 and 2015 in 82 LM-HICs from the six World Health Organization (WHO) regions. For those countries with repeated time point data in this study, we used data from the most recent survey. We estimated weighted prevalence of suicidal ideation and anxiety by country, region and at a global level with the following questions:-"Did you ever seriously consider attempting suicide during the past 12 months?" and "During the past 12 months, how often have you been so worried about something that you could not sleep at night?". We used multiple binary logistic regression to estimate the adjusted association between adolescent age, sex, socioeconomic status, peer support, parent-adolescent relationship, peer victimization, conflict, isolation and loneliness with suicidal ideation and anxiety.

FINDINGS

The sample comprised of 275,057 adolescents aged 12-17 years (mean age was 14.6 (SD 1.18) years of whom 51.8% were females). The overall 12 months pooled prevalence of suicidal ideation and anxiety were 14.0% (95% CI 10.0-17.0%) and 9.0% (7.0-12.0%) respectively. The highest pooled prevalence of suicidal ideation was observed in the Africa Region (21.0%; 20.0-21.0%) and the lowest was in the Asia region (8.0%, 8.0-9.0%). For anxiety, the highest pooled prevalence was observed in Eastern Mediterranean Region (17.0%, 16.0-17.0%) the lowest was in the European Region (4.0%, 4.0-5.0%). Being female, older age, having a lower socioeconomic status and having no close friends were associated with a greater risk of suicidal ideation and anxiety. A higher levels of parental control was positively associated with a greater likelihood of experiencing suicidal ideation (OR: 1.65, 1.45-1.87) and anxiety (1.53, 1.30-1.80). Parental understanding and monitoring were negatively associated with mental health problems. Similarly, the odds of experiencing suicidal ideation and anxiety were higher among adolescents who had been experiencing peer conflict (1.36, 1.24-1.50; 1.54, 1.40-1.70), peer victimization (1.26, 1.15-1.38; 1.13, 1.02-1.26), peer isolation (1.69, 1.53-1.86; 1.76, 1.61-1.92) and reported loneliness (2.56, 2.33-2.82; 5.63, 5.21-6.08).

INTERPRETATIONS

Suicidal ideation and anxiety are prevalent among adolescents although there is significant global variation. Parental and peer supports are protective factors against suicidal ideation and anxiety. Peer based interventions to enhance social connectedness and parent skills training to improve parent-child relationships may reduce suicidal ideation and anxiety. Research to inform the factors that influence country and regional level differences in adolescent mental health problems may inform preventative strategies.

Global variation in the prevalence of bullying victimisation amongst adolescents: Role of peer and parental supports

BACKGROUND

Bullying victimisation is a global public health problem that has been predominantly studied in high income countries. This study aimed to estimate the population level prevalence of bullying victimisation and its association with peer and parental supports amongst adolescents across low and middle income to high income countries (LMIC-HICs).

METHODS

Data were drawn from the Global School-based Student Health Survey of school children aged 12-17 years, between 2003 and 2015, in 83 LMIC-HICs in the six World Health Organization (WHO) regions. We estimated the weighted prevalence of bullying victimisation at country, region and global level. We used multiple binary logistic regression models to estimate the adjusted association of age, gender, socioeconomic status, and parental support and peer support, and country level variables (GDP and government expenditure on education) with adolescent bullying victimisation.

FINDINGS

Of the 317,869 adolescents studied, 151,036 (48%) were males, and 166,833 (52%) females. The pooled prevalence of bullying victimisation on one or more days in the past 30 days amongst adolescents aged 12-17 years was 30·5% (95% CI: 30·2-31·0%). The highest prevalence was observed in the Eastern Mediterranean Region (45·1%, 44·3-46·0%) and African region (43·5%, 43·0-44·3%), and the lowest in Europe (8·4%, 8·0-9·0%). Bullying victimisation was associated with male gender (OR: 1·21; 1·11-1·32), below average socio-economic status (OR: 1·47, 1·35-1·61), and younger age (OR: 1·11, 1·0-1·24). Higher levels of peer support (0·51, 0·46-0·57), higher levels of parental support (e.g., understanding children's problems (OR: 0·85, 0·77-0·95), and knowing the importance of free time spent with children (OR: 0·77, 0·70-0·85)), were significantly associated with a reduced risk of bullying victimisation.

INTERPRETATIONS

Bullying victimisation is prevalent amongst adolescents globally, particularly in the Eastern Mediterranean and African regions. Parental and peer supports are protective factors against bullying victimisation. A reduction in bullying victimisation may be facilitated by family and peer based interventions aimed at increasing social connectedness of adolescents.

The 'developmental gradient' revisited: Australian children's time with adult caregivers from infancy to middle childhood

Children's time use patterns represent a potentially important mechanism for the transmission of disadvantage across generations. Recent international research indicates that more educated mothers tailor the content of time with children to favour activities that are particularly important at different developmental stages - a finding that has been termed the 'developmental gradient'. Using time diary data for a sample of Australian children, this paper seeks to extend previous work in several ways. We first establish whether a 'developmental gradient' exists in Australian children's time with mothers, comparable to the results from international studies. We go further, however, by extending the analysis to consider time investments provided by fathers and other adult caregivers, and examining the importance of resources for explaining the patterns of time use. Consistent with theory, our results indicate that educational gaps in time spent 'teaching' are largest in the 4-5 age group, gaps in 'play' time with fathers are largest for toddlers (2-3), and gaps in 'enrichment' are largest for 6-7 and 8-9. Time with parents appears to be the primary driver of observed patterns of time spent 'teaching' and 'playing', while for 'enrichment,' differences are distributed across caregivers, but largest for non-parent caregivers. These results are not driven by differential access to resources. Our results suggest that the developmental gradient represents a plausible mechanism for the transmission of intergenerational disadvantage in Australia, and that policy responses focussed on better educating parents to understand the developmental needs of their children are likely to be an effective response.

Gender disparities and psychological distress among humanitarian migrants in Australia: a moderating role of migration pathway?

BACKGROUND

The role of migration pathway (refugees vs. asylum seekers) is seldom addressed in extant literature that looks at gender and mental health of humanitarian migrants. The aim of this study is to assess the relationship between gender and psychological distress among humanitarian migrants in Australia including the potential moderating role of migration pathway.

METHODS

We analyse data from 2399 humanitarian migrants that participated in the first wave of Building a New Life in Australia, a survey of humanitarian migrants in Australia, using Ordinary Least Squares multivariate regression.

RESULTS

Women report significantly higher psychological distress than men. Migration pathway moderates the relationship between gender and psychological distress with women asylum seekers reporting higher psychological distress. There is also a significant association between pre-migration trauma, settlement arrangements (particularly those associated with finance, housing, getting used to life in Australia and loneliness) and psychological distress.

CONCLUSIONS

Findings indicate higher psychological distress among asylum seeking women and suggest the importance of migrant status in predicting psychological distress. Settlement arrangements are key predictors of psychological distress among humanitarian migrants. While strategies aimed at addressing their mental health are warranted, policies aimed at the broader social determinants of health are needed to alleviate some of their mental distress especially in light of the recent changes to the Australian Refugee and Asylum-seeking policies.

Birth cohort, ageing and gender ideology: Lessons from British panel data

Individuals' gender attitudes influence their behaviors, and adherence to traditional gender ideology is an important mechanism contributing to the (re)production of gender inequalities. In developed nations, the 'gender revolution' was accompanied by marked societal shifts towards gender-egalitarian attitudes, but these trends have recently stalled. In this paper, we re-examine the role of birth cohort and ageing in influencing gender ideology through the lens of life-course theory and leveraging British panel data. We contribute to the field by considering cohort-differences in ageing effects on gender ideology and documenting within-cohort variability in such effects. We find that (i) people from older cohorts hold comparatively more traditional gender attitudes, (ii) the effect of ageing on gender ideology is positive, (iii) there are cohort-differences in these ageing effects, (iv) gender-attitude trajectories are less predictable in younger than older cohorts, and (v) factors capturing life-course experience explain little of the cohort differences. Our findings highlight important avenues for future research on gender ideology change, and offer insights into the likely pace and direction of social movements towards gender egalitarianism.

The scars of the past? Childhood health and health differentials in later life

This study estimates multilevel mixed effects models of three retrospective measures of childhood health – self-rated childhood health, exposure to parental smoking growing up, and missing school for 30 or more consecutive days due to a health event – on levels and changes in physical functioning at age 50 and beyond. Using data from 15 waves of the Household, Income and Labour Dynamics in Australia survey, the results show that variation in the level of later-life physical functioning is associated with childhood health. Poor childhood health however is not associated with the rate of physical functioning decline. Respondents who reported poor childhood health and were migrants to Australia from a non-English speaking country reported better physical functioning in later life, compared with non-Indigenous Australian-born respondents who reported poor childhood health. In contrast, women who reported poor self-rated childhood health reported worse physical functioning compared with men who reported poor self-rated childhood health. These findings are robust to the inclusion of a range of measures of childhood and adult characteristics and circumstances. These results suggest that Australia, with arguably a strong and supportive health care system as compared with the U.S., may mitigate the accumulation of disadvantages to those who reported poor childhood health. We note that though functional health differences due to childhood health are not exacerbated in later life, neither are they eliminated.

•

Poor childhood health is associated with worse physical functioning in later life.

•

This association is stronger for women, as compared with men.

•

Association weaker for migrants non-English speaking countries, vs. native-born.

Large-area electrode design for vertical electrical impedance scanning of concrete bridge decks

Vertical electrical impedance (VEI) testing is a method that was developed specifically for quantifying the level of protection against chloride ingress in concrete bridge decks. A significant operational difficulty associated with VEI testing has been establishing the required rebar tap as a ground reference. As described in this work, the use of a large-area electrode (LAE) can potentially remove the need for a rebar tap and therefore significantly simplify and accelerate the VEI testing process. The specific objective of the research was to develop both theoretical and practical guidance for the design of an LAE for VEI testing. To investigate several variables that can affect the accuracy of VEI measurements obtained using an LAE connection, including various combinations of deck cover and water resistivity values, electrode separation distance, counter electrode (CE) effective area, and area ratio between the LAE and the CE, an analytical model (AM) and a finite-element model (FEM) were developed and validated with laboratory and field experiments. From the results of the AM and FEM simulations and the results of the laboratory and field experiments, LAE design considerations were developed for each of these variables that should allow proper implementation of a VEI measurement system using an LAE connection.

The power of linked data: Evaluating diverse multi-program projects designed to reduce welfare dependence

This presentation showcases the innovative use of linked government administrative data in Australia to evaluate a range of diverse social interventions aimed at supporting vulnerable groups to achieve economic independence. The interventions were developed and funded as part of the Australian Priority Investment Approach to Welfare, an approach supported by actuarial analyses of administrative data designed to deliver targeted support for groups at-risk of long-term welfare dependence. In 2018, the Australian Government, commissioned an impact evaluation to assess the effectiveness of the approach in achieving its intended outcomes. The evaluation is based on analyses of linked administrative data to assess the extent to which the new interventions enabled pathways out of welfare dependence. Our presentation will outline the strengths and weaknesses of using government administrative data to evaluate the outcomes. Strengths include easy comparison across diverse programs designed to achieve the same goals; reduced respondent reporting burdens; robust quasi-experimental techniques such as a matching design based on exact matching on a few key characteristics and/or propensity score matching on a broad range of pre-program characteristics; and evidence-based investment practice decisions. Weaknesses include the adoption of an observational rather than experimental design and the lack of information on some social characteristics such as orientations to work, attitudes and social values. The presentation not only assesses the compilation of administrative data used for the first time to evaluate multi-program projects, it will also describe how these data feed into visual interactive dashboards used to monitor the outcomes of the interventions.

Prevalence of Mental Disorders Among Children and Adolescents of Parents with Self-Reported Mental Health Problems

This paper provides Australian population-level estimates of the prevalence of parental self-reported lifetime mental disorders and past 12 month mental disorders in their children. It leverages unique data from the 2013-2014 Australian Child and Adolescent Survey of Mental Health and Wellbeing (Young Minds Matter) (n = 6310). Mental disorders were assessed in 4-17 year-olds using the Diagnostic Interview Schedule for Children Version IV. Primary carer (PC) and secondary carer mental health was based on PC-reported lifetime diagnoses. Over one-third of 4-17 year-olds had a PC with a lifetime diagnosis. The prevalence of all disorders was significantly higher amongst these children than children whose PC reported no diagnoses, and highest when the PC had comorbid and more severe disorders. Assessing mental health needs at a family level is important to identify children who are particularly vulnerable to developing mental disorders, to develop targeted interventions, and to understand the intergenerational transmission of risk.

Maternal employment and children's socio-emotional outcomes: an Australian longitudinal study

OBJECTIVES

Among children, poor socio-emotional functioning leads to poor health and well-being during childhood and later in life, and so understanding its social determinants is important. This study's objective is to examine how maternal employment influences children's socio-emotional outcomes in an Australian sample of families with two biological parents, testing the mediating role of maternal mental health, parenting practices, and parental income.

METHODS

We analyze six waves of panel data from the Longitudinal Study of Australian Children (n = 7524 children, 29,701 observations) using random-effect models.

RESULTS

Children of employed mothers display better socio-emotional outcomes than children of non-employed mothers, though the effect magnitude is only moderate. Associations are stronger for internalizing than externalizing problems, and not mediated by parental mental health, parenting practices, or household income.

CONCLUSIONS

Our findings can inform sociopolitical debates on the social value of maternal labor force participation and its impacts on children. They suggest that incentivizing maternal employment should bear no detrimental consequences on their children's socio-emotional functioning. The different associations found for children's internalizing and externalizing problems stress the value of distinguishing these constructs.

An unsettled bargain? Mothers' perceptions of justice and fairness in paid work

Mothers' return to work following childbirth is widely recognized as a key stage in establishing employment arrangements that disadvantage them in the long run. This article investigates why mothers accept these unequal arrangements using data from a qualitative study of 109 Australian mothers. It focuses on mothers' perceptions of the fairness and justice of the flexibility of arrangements they commonly enter into upon return to work. The article draws attention to the importance of different justice frameworks, distributive, procedural and interactional, in understanding women's acceptance of gender inequality in paid work. The results indicate that most mothers view their workplace arrangements as fair, consistent with a distributive justice framework. Many women also place great importance on interactional justice, particularly in their experiences in negotiating flexibility. The article also identifies differences across employment type with women in jobs with career prospects more likely to invoke interactional justice frameworks than women in jobs with few career prospects.

Heavy Alcohol Use in the Couple Context: A Nationally Representative Longitudinal Study

BACKGROUND

For young couples, a partner's heavy alcohol use may be a point of conflict and relationship distress, particularly when there are disparities in the severity of drinking across partners.

OBJECTIVE

The aim was to examine the longitudinal impact of discrepancies in heavy alcohol use, particularly in couples with parenting responsibilities.

METHODS

Data were obtained from 554 heterosexual couples (with at least one partner aged between 18 and 30 years of age) over two assessments from a well-established longitudinal study of Australian households.

RESULTS

Multilevel analyses (examining time within partners within couples) indicated a high level of couple-level variation in individual reports of relationship satisfaction. Discrepancies in heavy alcohol use were negatively associated with relationship satisfaction over the assessment period and this was significantly moderated by parenthood. More specifically, heavy drinking discrepancies were associated with lower relationship satisfaction amongst parents more than nonparents.

CONCLUSION

Among dissatisfied couples, managing discrepancies in alcohol use and helping heavy drinking partners may be an important intervention focus, particularly when providing professional support for young parents.

Gender and Class Analysis: The Position of Women in the Class Structure

Stratification theory has traditionally focused exclusively on the position of men in the occupational system, either ignoring women completely, or locating them through male heads of families. Recent feminist research has criticised the assumptions underlying this approach, arguing that sex-based inequalities are an inherent feature of the class system, and must therefore be incorporated into class analysis. At a theoretical level feminists have argued that to treat the family as a single unit in which all members belong to the same class position, ignores the existence of sexual inequalities within the fam ily. At an empirical level the increasing numbers of married women entering the workforce undermines the notion of the male head of household. This paper examines some of these issues focusing on the 'Goldthorpe debate' ( Sociology, 1983). It also draws on data col lected in Brisbane in 1984 to examine the existence of 'cross-class' families in which husband and wife occupy different class positions. The implications of the existence of cross-class families are dis cussed in relation to class theory.

Gender, justice and work: a distributive approach to perceptions of housework fairness

Most women and men report that the division of domestic labor in their household is fair, despite women undertaking approximately seventy percent of housework. This raises questions about how fairness is evaluated within partnerships. We explore how parenthood and relationship transitions affect perceptions of housework fairness using panel data from the Household, Income and Labour Dynamics in Australia Survey and panel regression models. Our results indicate that net of actual housework divisions, socio-demographic factors, time availability and relative resources, the transition to parenthood increases women's perceptions of housework fairness immediately following the birth of a child, but decreases them in the long run. Relationship transitions have no independent effects. Our findings suggest that parenthood transitions are associated with changes in women's identity, cognitive evaluations of fairness and feelings of entitlement, as indicated by distributive justice theory.
