Body dissatisfaction and the effects of perceptual exposure on body norms and ideals.

OBJECTIVE Body dissatisfaction is of high prevalence among women all over the Western world. It is often suggested that sociocultural processes are the main cause of such widespread dissatisfaction. Here, we consider how perceptual effects may influence ideas of body normality and body ideals. METHOD Women who varied on a measure of body dissatisfaction rated a range of bodies for how normal and ideal they looked. They were exposed to either thin or fat bodies, and then they rerated the bodies. RESULTS Womens perceptions of body normality and ideal were easily malleable by exposure. In addition, greater body dissatisfaction and internalization of the thin Western ideal were related to (i) a smaller most normal and ideal body, (ii) a greater discrepancy between the most normal and most ideal-rated body, and (iii) a reduced effect of exposure to fat bodies. DISCUSSION Reduced updating of perceptions of body normality and body ideals in response to experience may be one mechanism that maintains body dissatisfaction.

Body Dissatisfaction and Attentional Bias to Thin Bodies

OBJECTIVE Evidence for attentional biases to weight- and shape-related information in women with eating concerns is inconclusive. METHOD We investigated whether body dissatisfaction is associated with an attentional bias toward thin bodies using a modified dot probe task. RESULTS In three studies, we found that undergraduate females were faster to discriminate the direction of an arrow cue when it appeared in the location previously occupied by a thin than a fat body. This attentional bias toward thin bodies was found using extreme stimuli (thin and fat bodies) presented for 500 ms (Experiment 1), extreme stimuli presented for 150 ms (Experiment 2), and less extreme stimuli that were equated for perceived extremity, presented for 150 ms (Experiment 3). When the stimuli were equated on perceptual extremity, the more dissatisfied a woman was with her body, and the larger her own BMI, the less of an attentional bias she showed toward thin bodies. DISCUSSION Our results indicate that women have an attentional bias to thin bodies, which appears to be automatic. Contrary to prediction, this bias was weaker in women with greater BMI and body dissatisfaction. This result offers no support for the view that selective attention to thin bodies is causally related to body dissatisfaction.

Chronic Illness and Developmental Vulnerability at School Entry

OBJECTIVE: This study examined the association between chronic illness and school readiness, by using linked administrative population data. METHODS: The sample included children born in 2003–2004 who were residing in Western Australia in 2009 and had a complete Australian Early Development Census record (N = 22 890). Health and demographic information was also analyzed for 19 227 mothers and 19 030 fathers. The impact of child chronic illness on 5 developmental domains (social, emotional, language, cognitive, and physical) at school entry was analyzed. Analyses examined the association between child developmental outcomes and chronic illness generally, single or multiple chronic illness diagnosis, and diagnosis type. Logistic regression models estimated odds ratios for each outcome, adjusted for child, parent, and community sociodemographic variables. RESULTS: In the adjusted models, children with a chronic illness had an increased risk of being classified as developmentally vulnerable on all domains, compared with children without a chronic illness (20%–35% increase in risk). There was no increased risk for children with multiple chronic illness diagnoses over those with a single diagnosis (all Ps > .05). There was no evidence of a disease-specific effect driving this risk. CONCLUSIONS: Regardless of the number or type of conditions, chronic illness in young children is a risk factor for reduced school readiness. These effects were seen for health conditions not traditionally considered detrimental to school readiness, such as chronic otitis media. Thus, the implications of a broader range of chronic health conditions in early childhood on school readiness need to be considered.

Contact with the juvenile justice system in children treated with stimulant medication for attention deficit hyperactivity disorder: a population study

BACKGROUND Attention deficit hyperactivity disorder (ADHD) is the most frequent neurodevelopmental disorder in children and is sometimes noted retrospectively in young people and adults who are incarcerated. We aimed to investigate juvenile justice encounters in children with and without ADHD. METHODS Between January, 1995, and December, 2010, we did a population-based cohort study in Western Australia. Anonymised linked population data were obtained from the Western Australia Midwives Notification System. 12 831 non-Indigenous Australian children and young people aged 10-21 years, who were diagnosed and treated with stimulant drugs for ADHD and had a record in the Monitoring Drugs of Dependence System (ADHD cohort), were identified and frequency-matched by age, sex, and socioeconomic status to 29 722 non-Indigenous Australian children and young people who had no record in the Monitoring Drugs of Dependence System (controls). Community correction records and incarceration records were retrieved for all participants from Total Offending Management Solutions. Our primary outcome was to compare justice outcomes between children with ADHD and those without this disorder. We compared cohorts by conditional logistic regression analysis. FINDINGS 9939 boys and 2892 girls were diagnosed and treated for ADHD; 22 875 boys and 6847 girls were frequency-matched controls. 792 (8%) boys and 75 (3%) girls with ADHD had a community correction record, compared with 822 (4%) boys and 75 (1%) girls without ADHD. 132 (1%) boys and 11 (<1%) girls with ADHD had an incarceration record, compared with 108 (<1%) boys and five (<1%) girls without ADHD. Compared with controls, boys with ADHD were two and half times more likely to have a community correction record (odds ratio 2·48, 95% CI 2·22-2·76) or an incarceration record (2·63, 2·01-3·44). Compared with their non-ADHD counterparts, girls with ADHD were nearly three times more likely to have a community correction record (odds ratio 2·86, 95% CI 2·03-4·03) and seven times more likely to have an incarceration record (7·27, 2·29-23·08). Boys with ADHD received their first community correction record at a younger age compared with controls (15·9 vs 16·3 years; p=0·0005), but age at first community correction record was similar for girls (16·5 vs 16·4 years; p=0·87). Burglaries and breaking and entering were the most common reason for a first justice record (total 659 [37%]), and this offence was twice as likely in children with ADHD (for boys, odds ratio 2·24, 95% CI 1·90-2·64; for girls, 2·19, 1·40-3·42). INTERPRETATION Justice outcomes for boys and girls were more frequent among children and young people treated for ADHD compared with their non-ADHD counterparts. Unlike girls, boys were more likely to offend at a younger age. Early diagnosis and management of children and young people with ADHD might reduce the over-representation of children with this disorder within the juvenile justice system.

Risk factors for repetition of a deliberate self-harm episode within seven days in adolescents and young adults: A population-level record linkage study in Western Australia.

Objective: The risk of repetition of deliberate self-harm peaks in the first 7 days after a deliberate self-harm episode. However, thus far no studies have examined the risk factors for repeating deliberate self-harm during this short-term period. We aimed to investigate the effects of socio-demographic factors, self-harm method and mental health factors in adolescents (10–19 years old) and young adults (20–29 years old). Methods: We used data linkage of population-wide administrative records from hospital inpatients and emergency departments to identify all the deliberate self-harm–related episodes that occurred in adolescents and young adults in Western Australia from 2000 to 2011. Logistic regression with generalised estimating equations was used for the analyses. Results: The incidence of repeating deliberate self-harm within the first 7 days after an index episode was 6% (403/6,768) in adolescents and 8% (842/10,198) in young adults. Socio-demographic risk factors included female gender and socioeconomic disadvantage. Compared with non-poisoning, self-poisoning predicted increased risk of having a repeated deliberate self-harm episode in males, but not in females. Borderline personality, impulse-control and substance use disorders diagnosed within one week before and one week after an index deliberate self-harm episode conferred the highest risk, followed by depressive and anxiety disorders. Having a preceding deliberate self-harm episode up to 7 days before an index episode was a strong predictor for the future repetition of a deliberate self-harm episode. Conclusion: Having a repeated deliberate self-harm episode within the first 7 days was related to a wide range of factors present at an index deliberate self-harm episode including socio-demographic characteristics, deliberate self-harm method and co-existing psychiatric conditions. These factors can inform risk assessments tailored to adolescents and young adults respectively to reduce the repetition of deliberate self-harm within a short but critical period, potentially contributing to reduce the repetition of deliberate self-harm in the long term.

School readiness of maltreated children: Associations of timing, type, and chronicity of maltreatment

Children who have been maltreated during early childhood may experience a difficult transition into fulltime schooling, due to maladaptive development of the skills and abilities that are important for positive school adaptation. An understanding of how different dimensions of maltreatment relate to childrens school readiness is important for informing appropriate supports for maltreated children. In this study, the Australian Early Development Census scores of 19,203 children were linked to information on child maltreatment allegations (substantiated and unsubstantiated), including the type of alleged maltreatment, the timing of the allegation (infancy-toddlerhood or preschool), and the total number of allegations (chronicity). Children with a maltreatment allegation had increased odds of poor school readiness in cognitive and non-cognitive domains. Substantiated maltreatment was associated with poor social and emotional development in children, regardless of maltreatment type, timing, or chronicity. For children with unsubstantiated maltreatment allegations, developmental outcomes according to the type of alleged maltreatment were more heterogeneous; however, these children were also at risk of poor school readiness irrespective of the timing and/or chronicity of the alleged maltreatment. The findings suggest that all children with maltreatment allegations are at risk for poor school readiness; hence, these children may need additional support to increase the chance of a successful school transition. Interventions should commence prior to the start of school to mitigate early developmental difficulties that children with a history of maltreatment allegations may be experiencing, with the aim of reducing the incidence of continuing difficulties in the first year of school and beyond.

The impact of child maltreatment on the risk of deliberate self-harm among adolescents: A population-wide cohort study using linked administrative records

Adolescents exposed to maltreatment have an elevated risk of deliberate self-harm (DSH). The aim of this study was to investigate longitudinally the effects of the number, timing, and type of maltreatment allegations on adolescent risk of having a DSH-related hospital admission, using linked data in Western Australia. A total of 351,372 children born between 1986 and 2000 were followed from birth up to the year 2010. Cox regression models were utilized, while controlling for a range of psychosocial covariates. Compared to children without allegations of maltreatment, children with unsubstantiated allegations only (aHR=1.04, 95%CI: 1.00-1.08, p<.01) and children with a substantiated allegation (aHR=1.10, 95%CI: 1.06-1.15, p<.001) all had significantly increased risk of DSH in adolescence. Among children with a substantiated allegation of maltreatment, the greater the number of allegations, the longer the exposure to maltreatment, and the more types of maltreatment experienced by a child, the higher the childs risk of DSH. However, this dose-response pattern was not found among children with unsubstantiated allegations only. This study calls for the early identification of children who are vulnerable to maltreatment, the better identification of the duration and severity of maltreatment experiences, and the provision of continued care and support, to reduce the childs DSH risk in adolescence.

Data linkage in an established longitudinal cohort: the Western Australian Pregnancy Cohort (Raine) Study.

The Western Australian Data Linkage System is one of a few comprehensive, population-based data linkage systems worldwide, creating links between information from different sources relating to the same individual, family, place or event, while maintaining privacy. The Raine Study is an established cohort study with more than 2000 currently active participants. Individual consent was obtained from participants for information in publicly held databases to be linked to their study data. A waiver of consent was granted where it was impracticable to obtain consent. Approvals to link the datasets were obtained from relevant ethics committees and data custodians. The Raine Study dataset was subsequently linked to academic testing data collected by the Western Australian Department of Education. Examination of diet and academic performance showed that children who were predominantly breastfed for at least 6 months scored higher academically at age 10 than children who were breastfed for less than 6 months. A further study found that better diet quality at ages 1, 2 and 3 years was associated with higher academic scores at ages 10 and 12 years. Examination of nutritional intake at 14 years of age found that a better dietary pattern was associated with higher academic performance. The detailed longitudinal data collected in the Raine Study allowed for adjustment for multiple covariates and confounders. Data linkage reduces the burden on cohort participants by providing additional information without the need to contact participants. It can give information on participants who have been lost to follow-up; provide or complement missing data; give the opportunity for validation studies comparing recall of participants with administrative records; increase the population sample of studies by adding control participants from the general population; and allow for the adjustment of multiple covariates and confounders. The Raine Study dataset is extensive and detailed, and can be further improved by linking to other external data sources. By linking educational outcomes to the Raine Study database, it was shown across three different age groups that a healthy diet was consistently associated with higher academic performance.

Literacy and Numeracy Underachievement in Boys and Girls With ADHD.

Objective: The aim was to determine literacy and numeracy outcomes, among children with and without ADHD by gestational age and gender. Method: De-identified linked population data from the Western Australian Monitoring of Drugs of Dependence System and Western Australian Literacy and Numeracy Assessment databases, and the Midwives Notification System used information on 6,819 children with ADHD compared with 14,451 non-ADHD children. Results: A total of 23% of boys and 28% of girls with ADHD had numeracy scores below the benchmark in School Year 3, compared with 11% of children without ADHD. These differences were also evident for reading, writing, and spelling through primary school. Children with ADHD and reduced gestational age were at a greater risk of not meeting numeracy and reading benchmarks, compared with children born at term. Conclusion: Children with ADHD are disadvantaged from an early age in key areas of learning, and this risk increased with reduction in gestational age at birth.

Western Australia unveils advances in linked data delivery systems

How matters are framed by the language we use is important to the messages communicated, as it affects how we think about and act on those messages.6 How we use words such as ‘sustainable’ in framing humanity’s current situation in relation to the environment is important. ‘Sustainability’ was defined by Brundtland in terms of sustainable development as “the management of environmental resources in such a way that the needs of the present generation are met without reducing the capacity of the next generation to meet their own needs”7 and this was adopted by the United Nations in the Agenda 21 Rio declaration at the Earth Summit in 1992.8
