RESUMO
Background: Risk-taking behaviours are a major contributor to youth morbidity and mortality. Vulnerability to these negative outcomes is constructed from individual behaviour including risk-taking, and from social context, ecological determinants, early life experience, developmental capacity and mental health, contributing to a state of higher risk. However, although risk-taking is part of normal adolescent development, there is no systematic way to distinguish young people with a high probability of serious adverse outcomes, hindering the capacity to screen and intervene. This study aims to explore the association between risk behaviours/states in adolescence and negative health, social and economic outcomes through young adulthood. Methods: The Raine Study is a prospective cohort study which recruited pregnant women in 1989-91, in Perth, Western Australia. The offspring cohort (N = 2,868) was followed up at regular intervals from 1 to 27 years of age. These data will be linked to State government health and welfare administrative data. We will empirically examine relationships across multiple domains of risk (for example, substance use, sexual behaviour, driving) with health and social outcomes (for instance, road-crash injury, educational underachievement). Microsimulation models will measure the impact of risk-taking on educational attainment and labour force outcomes. Discussion: Comprehensive preventive child health programmes and policy prioritise a healthy start to life. This is the first linkage study focusing on adolescence to adopt a multi-domain approach, and to integrate health economic modelling. This approach captures a more complete picture of health and social impacts of risk behaviour/âstates in adolescence and young adulthood.

Adolescent and parent reports of adolescent mental health problems often correlate poorly, and understanding this discrepancy has clinical importance. Yet contextual factors have only been inconsistently explained. At the 14- and 17-year follow-ups of the Western Australian Pregnancy Cohort (Raine) Study, 1,596 parent-child dyads completed the parent-reported Child Behaviour Checklist (CBCL) and the adolescent-rated Youth Self-Report (YSR). Maternal, family, adolescent, and parent factors were examined as potential predictors of discrepancies. When adolescent YSR scores were in the clinical range but parents' CBCL ratings were not, adolescents were more likely to report alcohol intoxication in the last 6 months, illicit drug use, low school motivation, and depression. When parents reported externalizing behaviour in the clinical range but adolescents did not, the characteristics associated with this were a younger maternal age, receiving social security benefit, stress related to parenting, depression, and poor family functioning. These new results will inform clinical management and research with adolescents who present with behavioural disorders. Statement of contribution What is already known on this subject? We know that adolescent and parent reports of adolescent mental health problems often correlate poorly, but little is known about which contextual factors lead to disagreement. Understanding the factors that influence agreement is clinically relevant for predicting and identifying externalizing behavioural disorders. This is a large-scale study with the ability to assess the impact of numerous psychosocial factors on instrument disagreement. What the present study adds We found that substance use, depression and low school motivation impacted on discrepancy in externalizing behaviour scores for 14-year-old male adolescents and their parents. Parental depression, stress, low family income, and family dysfunction also led to a higher likelihood of discrepancy in scores.

BACKGROUND: Australia's teenage birth rate has fallen to historic lows, but teenage motherhood still occurs and can be challenging for mother and baby. OBJECTIVE: The aim of this article is to review current evidence on the epidemiology and clinical care of teenage pregnancy and parenting, and provide recommendations around management of these young people in Australia. DISCUSSION: Teenage mothers may have experienced family, sexual, and partner violence, family disruption, and socioeconomic disadvantage. Outcomes on a range of peripartum measures are worse for teenage mothers and their babies. Longer term risks for the mother include depression and rapid repeat pregnancy; for the child, intergenerational teenage parenthood; and for both, socioeconomic disadvantage. Teenage motherhood occurs more often within communities where poverty, Aboriginal and Torres Strait Islander status and rural/remote location intersect. General practitioners play a critical role in identification of at-risk teens, preventing unintended teenage pregnancy, clinical care of pregnant teens, and promoting the health and wellbeing of teenage mothers and their children.

BACKGROUND: After the introduction of a quadrivalent human papillomavirus (HPV) vaccination programme in Australia in April, 2007, we measured the prevalence of vaccine-targeted and closely related HPV types with the aim of assessing direct protection, cross-protection, and herd immunity. METHODS: In this repeat cross-sectional study, we recruited women aged 18-24 years who attended Pap screening between October, 2005, and July, 2007, in three major metropolitan areas of Australia to form our prevaccine-implementation sample. For our postvaccine-implementation sample, we recruited women aged 18-24 years who attended Pap screening in the same three metropolitan areas from August, 2010, to November, 2012. We compared the crude prevalence of HPV genotypes in cervical specimens between the prevaccine and the postvaccine implementation groups, with vaccination status validated against the National HPV Vaccination Program Register. We estimated adjusted prevalence ratios using log linear regression. We estimated vaccine effectiveness both for vaccine-targeted HPV types (16, 18, 6, and 11) and non-vaccine but related HPV types (31, 33, and 45). FINDINGS: 202 women were recruited into the prevaccine-implementation group, and 1058 were recruited into the postvaccine-implementation group. Crude prevalence of vaccine-targeted HPV genotypes was significantly lower in the postvaccine-implementation sample than in the prevaccine-implementation sample (58 [29%] of 202 vs 69 [7%] of 1058; p<0·0001). Compared with the prevaccine-implementation sample, adjusted prevalence ratios for vaccine-targeted HPV genotypes were 0·07 (95% CI 0·04-0·14; p<0·0001) in fully vaccinated women and 0·65 (0·43-0·96; p=0·03) in unvaccinated women, which suggests herd immunity. No significant declines were noted for non-vaccine-targeted HPV genotypes. However, within the postvaccine-implementation sample, adjusted vaccine effectiveness against vaccine-targeted HPV types for fully vaccinated women compared with unvaccinated women was 86% (95% CI 71-93), and was 58% (26-76) against non-vaccine-targeted but related genotypes (HPV 31, 33, and 45). INTERPRETATION: 6 years after the initiation of the Australian HPV vaccination programme, we have detected a substantial fall in vaccine-targeted HPV genotypes in vaccinated women; a lower prevalence of vaccine-targeted types in unvaccinated women, suggesting herd immunity; and a possible indication of cross-protection against HPV types related to the vaccine-targeted types in vaccinated women.

INTRODUCTION: To date, no published studies examine procedural factors of the school-based human papillomavirus (HPV) vaccination program from the perspective of those involved. This study examines the factors that were perceived to impact optimal vaccination experience. METHODS: Schools across Sydney were selected to reflect a range of vaccination coverage at the school level and different school types to ensure a range of experiences. Semi-structured focus groups were conducted with girls; and one-on-one interviews were undertaken with parents, teachers and nurses until saturation of data in all emergent themes was reached. Focus groups and interviews explored participants' experiences in school-based HPV vaccination. Transcripts were analysed, letting themes emerge. RESULTS: Themes related to participants' experience of the organisational, logistical and procedural aspects of the vaccination program and their perceptions of an optimal process were organised into two categories: (1) preparation for the vaccination program and (2) vaccination day strategies. In (1), themes emerged regarding commitment to the process from those involved, planning time and space for vaccinations, communication within and between agencies, and flexibility. In (2), themes included vaccinating the most anxious girls first, facilitating peer support, use of distraction techniques, minimising waiting time girls, and support staff. DISCUSSION: A range of views exists on what constitutes an optimal school-based program. Several findings were identified that should be considered in the development of guidelines for implementing school-based programs. Future research should evaluate how different approaches to acquiring parental consent, and the use of anxiety and fear reduction strategies impact experience and uptake in the school-based setting.
