Suicides in Aboriginal and non-Aboriginal people following hospital admission for suicidal ideation and self-harm: A retrospective cohort data linkage study from the Northern Territory.

PURPOSE: This study aimed to explore risk factors for suicide in Aboriginal and non-Aboriginal people following hospital admission for suicidal ideation and self-harm in the Northern Territory, Australia to help clarify opportunities for improved care and intervention for these population groups. METHODS: Individuals with at least one hospital admission involving suicidal ideation and/or self-harm between 1 July 2001 and 31 December 2013 were retrospectively recruited and followed up using linked mortality records to 31 December 2014. Survival analyses stratified by Indigenous status identified socio-demographic and clinical characteristics from index hospital admissions associated with suicide. RESULTS: Just over half of the 4391 cohort members identified as Aboriginal (n = 2304; 52.4%). By 2014, 281 deaths were observed comprising 68 suicides, representing a 2.6% and 2.0% probability of suicide for Aboriginal and non-Aboriginal people, respectively. After adjusting for other characteristics, a higher risk of suicide was associated with male sex (Aboriginal adjusted hazard ratio: 4.14; 95% confidence interval: [1.76, 9.75]; non-Aboriginal adjusted hazard ratio: 5.96; 95% confidence interval: [1.98, 17.88]) and repeat hospital admissions involving self-harm (Aboriginal adjusted hazard ratio: 1.37; 95% confidence interval: [1.21, 1.55]; non-Aboriginal adjusted hazard ratio: 1.29; 95% confidence interval: [1.10, 1.51]). Severe mental disorders were associated with a four times higher risk of suicide (adjusted hazard ratio: 4.23; 95% confidence interval: [1.93, 9.27]) in Aboriginal people only. CONCLUSION: The findings highlight non-clinical risk factors for suicide that suggest the need for comprehensive psychosocial assessment tailored to Aboriginal and non-Aboriginal people hospitalised with suicidal ideation or self-harm. Implementing appropriate management and aftercare within a broader public health framework is needed to support recovery and reduce long-term suicide risk in the community, especially for Aboriginal people and males.

Unintended consequences of welfare reform: Evidence from birthweight of Aboriginal children in Australia.

In 2007, Australia introduced its most radical welfare reform in recent history, targeting Aboriginal communities with the aim of protecting children from harm. The 'income management' policy forced Aboriginal welfare recipients to spend at least half of their government transfers on essentials (e.g. food, housing), and less on non-essentials (e.g. alcohol, tobacco). By exploiting its staggered rollout, we estimate the impact of in utero exposure to the policy rollout on birthweight. We find that exposure to the income management policy reduced average birthweight robustly by 85 g and increased the risk of low birth weight by 3 percentage points. This finding is not explained by behavioral change (fertility, maternal risk behavior, access to care), or survival probabilities of at-risk fetuses. More likely, a lack of policy implementation planning and infrastructure led to acute income insecurity and stress during the rollout period, exacerbating the existing health inequalities it sought to address.

Validity and reliability of resiliency measures trialled for the evaluation of a preventative Resilience-promoting social-emotional curriculum for remote Aboriginal school students.

PURPOSE: We aimed to test the reliability and validity of two brief measures of resilience adopted for the evaluation of a preventative social-emotional curriculum implemented for Aboriginal middle school students from socially disadvantaged remote communities in Australia's Northern Territory. The questionnaires chosen were intended to measure psychological resilience and socio-cultural resilience as complementary dimensions of the capacity to cope in circumstances of significant life stress and risk of self-harm. METHODS: Confirmatory factor analysis (CFA) was conducted to assess construct validity of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), a measure of psychological resilience, and the 12-item Child and Youth Resilience Measure (CYRM-12), a measure of socio-cultural resilience, with a sample of 520 students. Associations between resilience and psychological distress and emotional and behavioural difficulty were analysed in relation to life stressors to assess criterion validity of the scales. RESULTS: CFA provided support for the validity of the respective constructs. There was good fit for both scales. However, assessment of criterion validity of the scales suggested that the adapted measure of socio-cultural resilience (CYRM-12NT) showed higher reliability and a clearer indication of predictive validity than the measure of psychological resilience (CD-RISC-10). CONCLUSIONS: The CYRM-12NT appears to be a more useful measure of resilience among Aboriginal youth exposed to significant life stress and disadvantage. However, both measures may require further development to enhance their validity and utility among potentially at-risk adolescents in socially, culturally and linguistically diverse remote Aboriginal communities.

School-Based Prevention in Very Remote Settings: A Feasibility Trial of Methods and Measures for the Evaluation of a Social Emotional Learning Program for Indigenous Students in Remote Northern Australia.

Purpose: Skills for Life (SFL) is a social-emotional curriculum for Indigenous middle school students that was co-developed with educators and community members in a remote community of northern Australia. This preliminary study aimed to test the feasibility of processes and methods of data-gathering, the reliability of youth self-report measures, and to identify the direction of effects for an evaluation of a longer-term pilot of the curriculum. Design/Methodology/Approach: Indigenous Students in years 7-9 of a remote school participated in SFL over 2 years. The Strengths and Difficulties Questionnaire (SDQ), Kessler 6 (K6), and a purpose-designed Connected Self Scale (CSS) were administered to 63 students pre- and post-program. Findings: Only the K6, Prosocial behavior (SDQ), and two CSS subscales showed sufficient internal consistency for analysis. Change was positive but non-significant for SDQ and CSS. There was evidence of a dosage effect: students receiving the intervention over 2 years showed greater reduction in psychological distress than other students. There was no evidence of iatrogenic effects. Conclusions: The feasibility pilot is a critically important phase in the development of evaluation design and cjhoice of evaluation measures for challenging remote settings. This study found that evaluation of SFL with culturally and linguistically distinct Indigenous middle school students using self-report measures is feasible. However, the SDQ may not be suitable for this project. High levels of psychological distress suggest the need to investigate sources of life stress and potential supports for adolescent resilience in this context. This preliminary pilot aimed to trial methods and measures for evaluation of a social-emotional curriculum developed specifically for remote Australian Indigenous students who are at risk of poor psychosocial outcomes. No studies have examined the appropriateness of standardized self-report measures for evaluation of SEL with this student population in remote school settings.

Aboriginal and Non-Aboriginal Emergency Department Presentations Involving Suicide-Related Thoughts and Behaviors.

Background: Rates of hospital admission for suicide-related thoughts and behaviors (SRTBs) are elevated in the Northern Territory (NT) of Australia, especially by Aboriginal people, but very little is known about emergency department (ED) presentations. Aim: We aimed to profile ED presentations in the NT involving SRTBs by Indigenous status and compare discharge arrangements. Method: Logistic regression analyses were performed on data from electronic patient records of consecutive ED presentations involving SRTBs. Results: During the study period, 167 presentations were observed. Aboriginal patients were more likely to present from remote areas and to report substance misuse and family conflict or violence compared with non-Aboriginal patients. In both groups, males were more likely than females to be admitted as were persons presenting with self-harm compared with those who had suicidal thoughts only. No differences in discharge arrangements were identified by Indigenous status. Limitations: The small scale of the study and use of administrative records points to the need for further research to improve the quality of the evidence. Conclusion: While presentations by high-risk groups are more likely to be admitted for further care, the assessment of psychosocial risks and needs in EDs is vital to informing decisions for aftercare that support recovery in the community for Aboriginal patients and patients discharged from EDs.

The Impact of Hearing Impairment on the Life Trajectories of Aboriginal Children in Remote Australia: Protocol for the Hearing Loss in Kids Project.

BACKGROUND: Previous studies have reported a high prevalence of chronic otitis media (OM) and hearing impairment (HI) in Aboriginal children in the Northern Territory (NT) of Australia. Children affected by these disorders are believed to be at increased risk for adverse outcomes in early childhood development, school attendance, academic performance, and child maltreatment and youth offending. However, to date, there have been no studies quantifying the association between HI and these outcomes in this population. OBJECTIVE: This study will investigate the association between HI and the 5 outcomes in Aboriginal children living in remote NT communities. METHODS: Individual-level information linked across multiple administrative datasets will be used to conduct a series of retrospective observational studies on selected developmental and school outcomes. The predictor variables for all studies are the results from audiometric hearing assessments. The outcome measures are as follows: Australian Early Development Census results, representing developmental readiness for school, assessed around 5 years of age; Year 1 school attendance rates; Year 3 school-based academic performance, assessed in the National Assessment Program-Literacy and Numeracy; incidence of child maltreatment events (including both notifications and substantiated cases); and incidence of a first guilty verdict for youth offenders. Confounding and moderating factors available for the analysis include both community-level factors (including school fixed effects, socioeconomic status, level of remoteness, and housing crowdedness) and individual-level factors (including maternal and perinatal health and hospital admissions in early childhood). RESULTS: The study commenced in 2018, with ethics and data custodian approvals for data access and linkage. This has enabled the completion of data linkage and the commencement of data analysis for individual component studies, with findings expected to be published in 2019 and 2020. CONCLUSIONS: This study will provide first evidence of the impact of OM-related HI on the developmental, educational, and social outcomes of Australian Aboriginal children. The findings are expected to have significant implications for policy development, service design, and resource allocation. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR1-10.2196/15464.

The impact of hearing impairment on Aboriginal children's school attendance in remote Northern Territory: a data linkage study.

OBJECTIVE: To investigate the association between hearing impairment (HI) and Year 1 school attendance in Aboriginal children in the Northern Territory (NT) of Australia. METHODS: Observational cohort study (n=3,744) by analysing linked individual-level information for Aboriginal children from the NT Government school attendance records, NT Perinatal Register and Remote Hearing Assessment dataset, and community level data for relative remoteness, socioeconomic disadvantage and housing crowdedness. RESULTS: Children with unilateral hearing loss, mild HI and moderate or worse HI had significantly lower Year 1 attendance than those with normal hearing, attending 5.6 (95%CI, -9.10 ∼-2.10), 4.0 (95%CI, -7.17 ∼-0.90) and 6.1 (95%CI, -10.71 ∼-1.49) days fewer, respectively. Other variables that yielded significant association were: male gender, having attended preschool less than 20% of available days, speaking English as second language, twin birth and average household size >5. CONCLUSIONS: Aboriginal children with any level of HI are likely to have lower school attendance rates in Year 1 than their peers with normal hearing. Implications for public health: In this population, where the prevalence of otitis media and accompanying HI remains extremely high, the early detection and management of hearing loss on entry into primary school should be included in the measures to improve school attendance.

Online scan of FASD prevention and health promotion resources for Aboriginal and Torres Strait Islander communities.

ISSUE ADDRESSED: Foetal Alcohol Spectrum Disorder (FASD) includes a range of life-long impairments caused by alcohol exposure in utero. Health professionals are vital to preventing FASD but many are hesitant to discuss FASD with clients due to their need for additional resources to aid the conversation. This scan sought to identify the scope and gaps in publicly available FASD prevention and health promotion resources, and assess their cultural appropriateness for use among five key groups of Indigenous Australian people including: (i) pregnant women, (ii) women of childbearing age, (iii) grandmothers and aunties, (iv) men, and (v) health professionals. METHODS: Relevant resources published 1995-2017 were identified through the Australian Indigenous HealthInfoNet, FASD organisation websites, grey literature, Google searches, and field experts. Results were screened by inclusion and cultural appropriateness criteria developed and piloted by the research team, and further screened by health professionals attending FASD training workshops. RESULTS: 115 of the 2146 identified resources were eligible. Relevant resources were found for all five key groups; however, no resources were specifically designed for men, grandmothers or aunties. CONCLUSIONS: A range of high-quality, culturally appropriate resources were identified, however, health professionals attending the training workshops were not aware of their availability. Further resource development is suggested for men, grandmothers and aunties. SO WHAT?: Prioritisation of active dissemination and implementation strategies is suggested to increase awareness and use of future resource developments. The inclusion of a resource trial among health professionals is a recommended strategy to increase awareness and use of newly developed resources.

Efficacy of the Aussie Optimism Program: Promoting Pro-social Behavior and Preventing Suicidality in Primary School Students. A Randomised-Controlled Trial.

The efficacy of an enhanced version of the Aussie Optimism Program (AOP) was investigated in a cluster randomized controlled trial. Grade 6 students aged 10-11 years of age (N = 2288) from 63 government primary schools in Perth, Western Australia, participated in the pre, post, and follow-up study. Schools were randomly assigned to one of three conditions: Aussie Optimism with teacher training, Aussie Optimism with teacher training plus coaching, or a usual care condition that received the regular Western Australian Health Education Curriculum. Students in the Aussie Optimism conditions received 20, 1-h lessons relating to social and interpersonal skills and optimistic thinking skills over the last 2 years of primary school. Parents in the active conditions received a parent information booklet each year, plus a self-directed program in Grade 7. Students and parents completed the Extended Strengths and Difficulties Questionnaire. Students who scored in the clinical range on the Emotional Symptoms Scale were given The Diagnostic Interview for Children and Adolescents IV, to assess suicidal ideation and behavior, and depressive and anxiety disorders. Results indicated that Aussie Optimism with teacher training plus coaching was associated with the best outcomes: a significant increase in student-reported pro-social behavior from pre-test to post-test 1 (maintained at post-test 2) and significantly lower incidence rates from suicidal ideation at post-test 2 and follow-up. No significant intervention effects on anxiety and depressive disorders, and total difficulties were reported. These findings suggest that the AOP with teacher training along with coaching may have the potential to positively impact on suicidality and pro-social behavior in the pre-adolescent years.

Efficacy of infant simulator programmes to prevent teenage pregnancy: a school-based cluster randomised controlled trial in Western Australia.

BACKGROUND: Infant simulator-based programmes, which aim to prevent teenage pregnancy, are used in high-income as well as low-income and middle-income countries but, despite growing popularity, no published evidence exists of their long-term effect. The aim of this trial was to investigate the effect of such a programme, the Virtual Infant Parenting (VIP) programme, on pregnancy outcomes of birth and induced abortion in Australia. METHODS: In this school-based pragmatic cluster randomised controlled trial, eligible schools in Perth, Western Australia, were enrolled and randomised 1:1 to the intervention and control groups. Randomisation using a table of random numbers without blocking, stratification, or matching was done by a researcher who was masked to the identity of the schools. Between 2003 and 2006, the VIP programme was administered to girls aged 13-15 years in the intervention schools, while girls of the same age in the control schools received the standard health education curriculum. Participants were followed until they reached 20 years of age via data linkage to hospital medical and abortion clinic records. The primary endpoint was the occurrence of pregnancy during the teenage years. Binomial and Cox proportional hazards regression was used to test for differences in pregnancy rates between study groups. This study is registered as an international randomised controlled trial, number ISRCTN24952438. FINDINGS: 57 (86%) of 66 eligible schools were enrolled into the trial and randomly assigned 1:1 to the intervention (28 schools) or the control group (29 schools). Then, between Feb 1, 2003, and May 31, 2006, 1267 girls in the intervention schools received the VIP programme while 1567 girls in the control schools received the standard health education curriculum. Compared with girls in the control group, a higher proportion of girls in the intervention group recorded at least one birth (97 [8%] of 1267 in the intervention group vs 67 [4%] of 1567 in the control group) or at least one abortion as the first pregnancy event (113 [9%] vs 101 [6%]). After adjustment for potential confounders, the intervention group had a higher overall pregnancy risk than the control group (relative risk 1·36 [95% CI 1·10-1·67], p=0·003). Similar results were obtained with the use of proportional hazard models (hazard ratio 1·35 [95% CI 1·10-1·67], p=0·016). INTERPRETATION: The infant simulator-based VIP programme did not achieve its aim of reducing teenage pregnancy. Girls in the intervention group were more likely to experience a birth or an induced abortion than those in the control group before they reached 20 years of age.

Challenges in monitoring the development of young children in remote Aboriginal health services: clinical audit findings and recommendations for improving practice.

INTRODUCTION: Early detection of developmental difficulties is universally considered a necessary public health measure, with routine developmental monitoring an important function of primary healthcare services. This study aimed to describe the developmental monitoring practice in two remote Australian Aboriginal primary healthcare services and to identify gaps in the delivery of developmental monitoring services. METHODS: A cross-sectional baseline medical record audit of all resident children aged less than 5 years in two remote Aboriginal health centres in the Northern Territory (NT) in Australia was undertaken between December 2010 and November 2011. RESULTS: A total of 151 medical records were audited, 80 in Community A and 71 in Community B. Developmental checks were more likely among children who attended services more regularly. In Community A, 63 (79%) medical records had some evidence of a developmental check and in Community B there were 42 (59%) medical records with such evidence. However, there was little indication of how assessments were undertaken: only one record noted the use of a formal developmental screening measure. In Community A, 16 (16%) records documented parent report and 20 (20%) documented staff observations, while in Community B, the numbers were 2 (3%) and 11 (19%), respectively. The overall recorded prevalence of developmental difficulties was 21% in Community A and 6% in Community B. CONCLUSIONS: This is the first study to describe the quality of developmental monitoring practice in remote Australian Aboriginal health services. The audit findings suggest the need for a systems-wide approach to the delivery and recording of developmental monitoring services. This will require routine training of remote Aboriginal health workers and remote area nurses in developmental monitoring practice including the use of a culturally appropriate, structured developmental screening measure.

Trends in hospital admissions involving suicidal behaviour in the Northern Territory, 2001-2013.

OBJECTIVE: To investigate trends in hospital admissions involving suicidal behaviour in the Northern Territory (NT) resident population over the period 2001-2013. METHODS: Estimates of age-standardised rates and average changes in the annual rate of hospital admissions involving suicidal behaviour were calculated by socio-demographic characteristics and types of suicidal behaviour. RESULTS: Overall rates for Indigenous admissions were 2.7 times higher than non-Indigenous admissions and had increased by almost twice as much. While male and female rates of admission were similar for both Indigenous and non-Indigenous residents, the average annual change in rates was greater for Indigenous females (13.4%) compared to males (8.8%) and for non-Indigenous males (7.7%) compared to females (5.2%). Younger and middle-aged Indigenous admissions experienced increasing rates of admissions, whilst trends were similar across age groups for non-Indigenous admissions. Admissions with a diagnosis of suicidal ideation increased the most across all groups. Trends in intentional self-harm admissions differed according to Indigenous status and sex. CONCLUSIONS: There have been substantial increases in hospital admissions involving suicidal behaviour in the NT, most markedly for Indigenous residents. Indigenous females and youth appear to be at increasing risk. The steep increase in suicidal ideation across all groups warrants further investigation.

Adaptation of the Ages and Stages Questionnaire for Remote Aboriginal Australia.

A key challenge to providing quality developmental care in remote Aboriginal primary health care (PHC) centers has been the absence of culturally appropriate developmental screening instruments. This study focused on the cross-cultural adaptation of the Ages and Stages Questionnaires, 3rd edition (ASQ-3), with careful attention to language and culture. We aimed to adapt the ASQ-3 for use with remote dwelling Australian Aboriginal children, and to investigate the cultural appropriateness and feasibility of the adapted ASQ-3 for use in this context. We undertook a qualitative study in two remote Australian Aboriginal communities, using a six-step collaborative adaptation process. Aboriginal Health Workers (AHWs) were trained to use the adapted ASQ-3, and follow-up interviews examined participants' views of the cultural acceptability and usefulness of the adapted instrument. The adapted ASQ-3 was found to have high face validity and to be culturally acceptable and relevant to parents, AHWs, and early childhood development experts.

Culturally Appropriate Training for Remote Australian Aboriginal Health Workers: Evaluation of an Early Child Development Training Intervention.

OBJECTIVE: This study aimed to design, implement, and evaluate training in early childhood development (ECD) and in the use of a culturally adapted developmental screening tool, for remote Australian Aboriginal Health Workers (AHWs) and other remote health practitioners. METHOD: A case-study evaluation framework was adopted. Two remote Australian Aboriginal health services were selected as case-study sites. Materials review, semistructured interviews, posttraining feedback surveys, and workplace observations contributed to the evaluation, guided by Guskey's 5-level education evaluation model. RESULTS: Remote health practitioners (including AHWs and Remote Area Nurses) and early childhood staff from the sites participated in a customized 2½ day training workshop focusing on the principles of ECD and the use of the culturally adapted Ages and Stages Questionnaire, third edition. Consistent with adult learning theories and recommendations from the literature regarding culturally appropriate professional development methods in this context, the workshop comprised interactive classroom training, role-plays, and practice coaching in the workplace, including booster training. The qualitative findings demonstrated that mode of delivery was effective and valued by participants. The workshop improved practitioners' skills, knowledge, competence, and confidence to identify and manage developmental difficulties and promote child development, evidenced on self-report and workplace clinical observation. CONCLUSION: The findings suggest that the practical, culturally appropriate training led to positive learning outcomes in developmental practice for AHWs and other remote health practitioners. This is an important finding that has implications in other Indigenous contexts, as effective training is a critical component of any practice improvement intervention. Further research examining factors influencing practice change is required.

Impact of perinatal health and socio-demographic factors on school education outcomes: A population study of Indigenous and non-Indigenous children in the Northern Territory.

AIM: This study investigated the association between early-life risk factors and school education outcomes. METHODS: This is an historical cohort study of 7601 children (61% were Indigenous) born in the Northern Territory between 1999 and 2004. Information was linked, for each child on: perinatal health, student enrolment and National Assessment Program - Literacy and Numeracy (NAPLAN) Year 3 results. Logistic regression was used to estimate the association between selected risk factors and a NAPLAN result 'below' the national minimum standard (NMS) in reading and numeracy. RESULTS: Indigenous children had much higher odds, than non-Indigenous children, of a result below the NMS for both reading (odds ratio (OR): 8.58, 95% confidence interval (CI): 7.55-9.74) ) and numeracy (OR: 11.52, 95% CI: 9.94-13.35). When adjusted for all other variables, the increased odds were attenuated for both reading (OR: 2.89, 95% CI: 2.46-3.40) and numeracy (OR: 3.19, 95% CI: 2.65-3.84). Common risk factors for Indigenous and non-Indigenous children included higher birth order, maternal smoking in pregnancy and being a boy. There were gradients of decreasing risk with increasing education level of primary care giver and increasing maternal age. Among Indigenous children only, risks increased when living in remote areas, with younger age (<8 years) and low birthweight. CONCLUSIONS: The study highlights that many of the risk factors associated with poor education outcomes among Indigenous children are shared with the general population. The results inform a targeted, cross-agency response to address modifiable early-life risk factors for educational disadvantage. Data linkage, using existing administrative datasets, provides a useful addition to methods that identify priority areas for prevention and early intervention.

Jurisdictional, socioeconomic and gender inequalities in child health and development: analysis of a national census of 5-year-olds in Australia.

OBJECTIVES: Early child development may have important consequences for inequalities in health and well-being. This paper explores population level patterns of child development across Australian jurisdictions, considering socioeconomic and demographic characteristics. DESIGN: Census of child development across Australia. SETTING AND PARTICIPANTS: Teachers complete a developmental checklist, the Australian Early Development Index (AEDI), for all children in their first year of full-time schooling. Between May and July 2009, the AEDI was collected by 14 628 teachers in primary schools (government and non-government) across Australia, providing information on 261 147 children (approximately 97.5% of the estimated 5-year-old population). OUTCOME MEASURES: Level of developmental vulnerability in Australian children for five developmental domains: physical well-being, social competence, emotional maturity, language and cognitive skills and communication skills and general knowledge. RESULTS: The results show demographic and socioeconomic inequalities in child development as well as within and between jurisdiction inequalities. The magnitude of the overall level of inequality in child development and the impact of covariates varies considerably both between and within jurisdiction by sex. For example, the difference in overall developmental vulnerability between the best-performing and worst-performing jurisdiction is 12.5% for males and 7.1% for females. Levels of absolute social inequality within jurisdictions range from 8.2% for females to 12.7% for males. CONCLUSIONS: The different mix of universal and targeted services provided within jurisdictions from pregnancy to age 5 may contribute to inequality across the country. These results illustrate the potential utility of a developmental census to shed light on the impact of differences in universal and targeted services to support child development by school entry.

Associations between anxious-depressed symptoms and cardiovascular risk factors in a longitudinal childhood study.

OBJECTIVE: To examine the influence of anxious/depressed scores on cardiovascular risk factors throughout childhood. METHODS: Data from the Western Australian Pregnancy Cohort (Raine) Study, a study of 2900 pregnancies recruited between 1989 and 1991, were used. Anxious-depressed scores (derived from the Childhood Behavior Checklist), body mass index (BMI) and blood pressure were measured at 5 (n=1681), 8 (n=1697), 10 (n=1575) and 14 (n=1386) years. At age 14 depressive symptom scores (Beck Depression Inventory for Youth), anxious-depressed scores (Youth Self-Report (YSR) and Teacher Report Form (TRF)) and fasting lipid, glucose and insulin were also available. Cross sectional and longitudinal analyses were conducted. RESULTS: At age 14, girls with higher anxious-depressed scores had higher BMI (p≤ 0.005) and homeostasis model assessment-estimated insulin resistance (p≤ 0.0001). This equated to a difference of 0.6 kg/m(2) and 0.3 units in predicted BMI and HOMA-IR respectively (top 5% vs. score of zero). Boys with higher anxious-depressed scores had lower systolic blood pressure trajectories (p=0.024). CONCLUSION: Depressive scores appear to have differing influences on BMI, homeostasis model assessment-estimated insulin resistance and systolic blood pressure in boys and girls. Paradoxically boys with higher anxious-depressed scores had lower blood pressure throughout childhood.

Dietary intake of omega-3 fatty acids and risk of depressive symptoms in adolescents.

BACKGROUND: Previous randomized controlled trials have demonstrated that omega-3 polyunsaturated fatty acids (n-3 PUFA) are beneficial in reducing symptoms of depression. However, there is limited evidence regarding the influence of dietary n-3 PUFA intake on mood in adolescents drawn from population studies. OBJECTIVE: In the present investigation, we examined the relationship between dietary n-3 PUFA intake on depression symptomatology in a large prospective pregnancy cohort followed for 17 years. METHODS: Adolescents enrolled in the Western Australian Pregnancy Cohort (Raine) Study completed a Food Frequency Questionnaire to assess dietary fatty acid intake, as well as other dietary factors at age 14 and a fasting blood sample was taken. Participants also completed the Beck Depression Inventory for Youth (BDI-Y) at age 14 (N = 1,407) and at age 17 (N = 995). RESULTS: An inverse relationship was observed between intake of both saturated fat and of n-3 PUFA at age 14 and BDI-Y scores at both 14 and 17 years of age. However, after adjusting for energy (kJ) intake and other lifestyle confounders, the relationships were no longer significant. CONCLUSIONS: Associations previously reported between n3 PUFA and depressive symptoms may be due to collinearity with other dietary and lifestyle factors.

Lifestyle and demographic correlates of poor mental health in early adolescence.

AIM: To determine the constellation of lifestyle and demographic factors that are associated with poor mental health in an adolescent population. METHODS: The Raine Study 14-year follow-up involved primary care givers and their adolescent children (n= 1860). The Child Behaviour Checklist (CBCL) was used to assess adolescent mental health. We examined diet, socio-demographic data, family functioning, physical activity, screen use and risk-taking behaviours with mental health outcomes using linear regression. RESULTS: Adolescents with higher intakes of meat and meat alternatives and 'extras' foods had poorer mental health status. Adverse socio-economic conditions, higher hours of screen use and ever partaking in the health risk behaviours of smoking and early sexual activity were significantly associated with increasing CBCL scores, indicative of poorer functioning. CONCLUSIONS: By identifying the lifestyle and demographic factors that accompany poorer mental health in early adolescence, we are able to better understand the context of mental health problems as they occur within an adolescent population.
