Objectives: This study aimed to determine whether family poverty over the early childhood, adolescent, and adult periods of the life course independently predicts experiences of intimate partner violence (IPV) in adulthood., Study Design: This was a birth cohort study in Brisbane, Australia, with pregnant women recruited at their first booking-in visit and their children, followed up to 30 and 40 years of age., Methods: Family income was obtained from the mother when the child was 6 months, 5 and 14 years of age. Offspring reported their own family income at 21, 30, and 40 years of age. The offspring completed the Composite Abuse Scale at 30 and 40 years. Adjusted logistic regression models are used to predict experiences of IPV at 30 (n = 2157) and 40 (n = 1438) years., Results: The findings at 30 and 40 years of age are consistent. Only poverty experienced concurrently with the assessment of IPV is strongly associated. At the 40-year follow-up, family poverty predicts higher ratios of all four forms of IPV; severe combined abuse (odds ratio [OR] = 2.24, 95% confidence interval [CI] = 1.24, 4.05), physical abuse (OR = 3.37, 95% CI = 1.95, 5.82), emotional abuse (OR = 2.09, 95% CI = 2.58, 8.57) and harassment (OR = 4.70, 95% CI = 2.58, 8.57)., Conclusion: Concurrent family poverty is strongly and consistently associated with patterns of IPV. These associations are for cross-sectionally collected data with the prospectively collected data not replicating these findings. Although it is not possible to identify a specific causal pathway, the findings suggest that the immediate consequences of poverty are strongly associated with IPV. Programmes that address poverty reduction provide the best prospect for reducing societal levels of IPV., (Copyright © 2024 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Background and Aims: Substance use treatment (SUT) has shown to be effective in reducing self-reported offending; however, the association between SUT completion and criminal justice system (CJS) contact has been underexplored, especially in Latin America. This study aimed to estimate the association between SUT completion status and (1) any subsequent CJS contact and (2) CJS contact leading to imprisonment, at 1, 3 and 5 years post-discharge, in Chile., Design: Retrospective cohort study using multivariable survival analysis based on linked administrative data from 2010 to 2019., Setting: This study took place in Chile, where SUT is available at no cost through Chile's publicly funded health-care, and is provided in outpatient and inpatient modalities in public and private centres., Participants: A total of 70 854 individuals received their first SUT from 2010 to 2019. They were mainly males (76.3%), and their main substance used at admission was cocaine paste (39.2%)., Measurements: SUT completion status included completion, late dropout (≥ 3 months) and early dropout (< 3 months). Outcomes were (1) any CJS contact and (2) CJS contact leading to imprisonment after baseline treatment. We estimated the association between treatment completion and CJS contact through flexible parametric Royston-Parmar models while adjusting for several covariates., Findings: Those who completed SUT (27.2%) were less likely to have any CJS contact at 5 years post-SUT compared with those who dropped out late [with a gap of -9.5%, 95% confidence interval (CI) = -8.7, -10.3] and early (-11.2%, 95% CI = -10.1, -12.3). Also, those who completed SUT were less likely to have CJS contact leading to imprisonment at 5 years post-SUT compared with those who dropped out late (-2.6%, 95% CI = -2.2, -3.1) and early (-4.0%, 95% CI = -3.3, -4.6). These differences were also observed at 1 and 3 years post-SUT for each outcome., Conclusions: In Chile, completion of substance use treatment appears to be associated with lower probabilities of both any criminal justice system contact and contact leading to imprisonment., (© 2024 The Authors.

Background: Evidence supports the conceptualization of adult attachment as existing along a continuum of attachment security and insecurity; however, ongoing debates persist regarding the use of categorical versus continuous approaches to studying attachment. Attachment data collected from a large community sample of mothers and their offspring in young adulthood were used to examine i) latent classes of adult attachment, ii) associations between mother and offspring attachment, iii) the relationship between adult attachment and mental health symptoms., Methods: Mothers and offspring were each administered the Attachment Style Questionnaire when offspring were aged 21-years. Latent class analyses (LCA) were performed to examine response patterns across ASQ items. Associations between mothers' and offspring attachment, and correlations between attachment domains and depression/anxiety subscales were examined., Results: LCA identified four latent classes across a continuum of secure and insecure attachment rather than four distinct adult attachment styles. Anxious attachment subscales correlated strongly with depression/anxiety symptoms in both cohorts. Mothers' attachment was significantly but weakly correlated with their young adult offspring attachment., Limitations: Attachment was measured at one time point and as such, a causal maternal-offspring attachment relationship could not be established., Conclusions: Findings support a dimensional view of attachment security and insecurity over a four-category model of adult attachment. Attachment correlated with anxiety and depressive symptoms and highlights the importance of considering adult attachment when addressing mental health. There was limited evidence of a relationship between middle aged mothers and their offspring in young adulthood, suggesting other factors influence attachment in adulthood., Competing Interests: Declaration of competing interest The authors do not have any competing interest to report., (Crown Copyright © 2024.

Background and Aims: Gender differences in cardiovascular disease (CVD) have been well documented but rarely for young adults and the extent to which gender related lifestyle differences may contribute to gender differences in CVD risk experienced by young adults have not been reported., Methods and Results: Data are from a long-running cohort study, the Mater-University of Queensland Study of Pregnancy (MUSP). We track gender differences in CVD related behaviours at 21 and 30 years (consumption of a Western Diet/Health-Oriented Diet, cigarette smoking, vigorous physical exercise, heavy alcohol consumption). At 30 years we compare males and females for CVD risk, and the extent to which lifestyle behaviours at 21 and 30 years contribute to CVD risk. At both 21 and 30 years of age, males more frequently consume a Western Diet and less often a Health Oriented Diet. By contrast, males are also much more likely to report engaging in vigorous physical activity. On most CVD markers, males exhibit much higher levels of risk than do females at both 21 and 30 years. At 30 years of age males have about five times the odds of being at high risk of CVD. Some lifestyle behaviours contribute to this additional risk., Conclusion: Young adult males much more frequently engage in most CVD related risk behaviours and males have a higher level of CVD risk. Gender differences in CVD risk remain high even after adjustment for CVD lifestyles, though dietary factors independently contribute to CVD risk at 30 years., Competing Interests: Declaration of competing interest There are no competing interests., (Copyright © 2023 The Authors.

Background: Use of tobacco and cannabis is common and has been reported to predict lung function. Less is known about co-use of tobacco and cannabis and their impact on changes in lung function to early adulthood., Research Question: The study examines whether cigarette smoking or cannabis use and co-use are each associated with lung function in a population sample of young adults., Study Design and Methods: Data are from a prospective cohort study of cigarette smoking, cannabis use and co-use at 21 and 30 years of age and lung function (FVC, FEV 1 , FEV 1 /FVC) measured at 30 years. Lung function results are transformed using Global Lung Function Formulae. Subjects are the children of pregnant women who were recruited into the cohort study over the period 1981-3. Respondents were administered a spirometry assessment at 21 and 30 years of age. These respondents completed a smoking and cannabis use questionnaire at 21- and 30-year follow-ups., Results: Cigarette smoking (with or without cannabis use) is associated with reduced airflow. There is no consistent association between cannabis use and measures of lung function. The co-use of tobacco and cannabis appears to entail no additional risk to lung function beyond the risks associated with tobacco use alone., Interpretation: Persistent cigarette smoking is associated with reduced airflow even in young adults. Cannabis use does not appear to be related to lung function even after years of use., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2023 Elsevier Ltd.

Background: The long-term mental and physical health consequences of childhood maltreatment have been well documented. Less known are the longer-term consequences of childhood maltreatment, specifically the extent to which childhood maltreatment predicts adult life success., Objectives: To prospectively assess the extent to which childhood experiences of physical, sexual, emotional abuse and childhood neglect predict life success at 30 years of age., Participants and Setting: Data are from the Mater-University of Queensland Study of Pregnancy (MUSP), a pre-birth cohort study which follows children from conception to 30 years of age., Methods: Details of childhood maltreatment are from two sources; child safety agency notifications (and substantiations) linked to the survey data with self-reports of childhood experiences of maltreatment obtained at the 30-year follow-up using the Child Trauma Questionnaire (CTQ). Life success is a 9-item composite measure (alpha = 0.76) obtained at the 30-year follow-up. We use logistic regression models (with control for covariates) to examine the association between overall as well as specific forms of childhood maltreatment on adult life success. We further test these models using different cut-offs and propensity analyses to adjust for loss to follow-up., Results: Childhood maltreatment whether measured by agency report or self-report predicts overall low life success; agency substantiation OR = 1.88(1.14,3.08) & self-report OR = 2.60 (2.10,3.25). Self-report physical abuse, OR = 2.37(1.72,3.28); sexual abuse, OR = 2.85(2.05,3.96); emotional abuse, OR = 2.53(1.85,3.45) and neglect, OR = 2.36(1.83,3.03) all predict higher levels of low life success., Conclusions: Our findings suggest that the long-term consequences of childhood maltreatment extend to a wide range of day-to-day circumstances and extend into mid- to later life.

A range of adult health outcomes have been linked to early childhood adversities. These early adversities include parental marital breakdown and family economic disadvantage. Childhood experiences of maltreatment have also been linked to a variety of adult health outcomes. As both childhood adversities and child maltreatment often co-occur, we examine whether childhood adversities at 3 stages of the child's early life course predict any of nine adult mental health outcomes controlling for past experiences of child trauma (maltreatment). Data are from a long running birth cohort study, the Mater-University of Queensland Study of Pregnancy (MUSP). We use bivariate and multinomial logistic regression with adjustment for confounding, to predict adult outcomes. Experiences of recent life events in pregnancy appear to be unrelated to adult mental health. Recent life events experienced at the 5-year follow-up independently predicts lifetime ever depression and cannabis use disorder. Experiences of recent life events at 14-years of age predict lifetime ever depression, cannabis and amphetamine use in adulthood. Our findings support early childhood interventions which should be supplemented with a focus on later childhood and the adolescent period of development. Interventions should also focus on the broader social and demographic context within which children are born. Efforts to reduce the occurrence and consequences of childhood maltreatment should be given primary attention in order to reduce the childhood factors contributing to adult mental illness., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

A large number of early life exposures predict child maltreatment. Using data from a 30-year birth cohort study we examine 12 early life course risk factors of four types of self-reported childhood maltreatment recalled at the 30-year follow-up. Of the 7223 children in the sample at birth, 2425 responded to the Child Trauma Questionnaire at the 30-year follow-up. On adjusted analysis being a teenage mother predicts childhood physical and sexual abuse, as well as child neglect. More numerous maternal marital partner changes in the 5 years after the birth predict offspring experiences of emotional abuse, sexual abuse and childhood neglect. Policy responses should focus on the broad social context in which children are reared as the most effective approach to reducing the high level of childhood abuse and neglect., (© 2021.

Objectives: Parental imprisonment is linked with child health in later life. The present study provides the first prospective cohort analysis and non-U.S. based study examining parental imprisonment and cardiometabolic risk factors in adolescence and adulthood., Methods: The study followed 7,223 children born from live, singleton births from 1981 to 1984 in Brisbane, Australia. Data on parental imprisonment was collected at mother interview when the children were ages 5 and 14. Our sample analyzes offspring with biometric data collected by health professionals, including 3,794 at age 14, 2,136 at age 21, and 1,712 at age 30. Analyses used multivariate linear and logistic regression, and time-varying growth curve models., Results: Among female respondents, parental imprisonment at ages ≤5 was associated with higher body-mass index (BMI) at ages 14, 21, and 30; higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) at age 30; and increased sedentary hours, larger waist circumference, and odds of a high-risk waist circumference at age 30. Parental imprisonment when the child was aged ≤14 was associated with increased BMI and SBP at age 30 for females. In growth-curve models, parental imprisonment when the child was aged ≤5 and ≤ 14 among females was linked with increased BMI; parental imprisonment when the child was aged ≤5 was associated with increased SBP and DBP. No significant associations were observed for males., Conclusions: Using prospective cohort data, our results support research showing that parental imprisonment, particularly in early childhood, is associated with increased BMI, blood pressure, sedentary hours, and waist circumference in females in early adulthood. These findings implicate parental imprisonment as a risk factor for cardiometabolic health issues in later life among females., Competing Interests: None for all authors., (© 2022 The Authors.)

Purpose: To describe official adult-onset offenders, investigate their antisocial histories and test hypotheses about their origins., Methods: We defined adult-onset offenders among 931 Dunedin Study members followed to age 38, using criminal-court conviction records., Results: Official adult-onset offenders were 14% of men, and 32% of convicted men, but accounted for only 15% of convictions. As anticipated by developmental theories emphasizing early-life influences on crime, adult-onset offenders' histories of antisocial behavior spanned back to childhood. Relative to juvenile-offenders, during adolescence they had fewer delinquent peers and were more socially inhibited, which may have protected them from conviction. As anticipated by theories emphasizing the importance of situational influences on offending, adult-onset offenders, relative to non-offenders, during adulthood more often had schizophrenia, bipolar disorder, and alcohol-dependence, had weaker social bonds, anticipated fewer informal sanctions, and self-reported more offenses. Contrary to some expectations, adult-onset offenders did not have high IQ or high socioeconomic-status families protecting them from juvenile conviction., Conclusions: A tailored theory for adult-onset offenders is unwarranted because few people begin crime de novo as adults. Official adult-onset offenders fall on a continuum of crime and its correlates, between official non-offenders and official juvenile-onset offenders. Existing theories can accommodate adult-onset offenders.

Objective: Antisocial behaviour in young people is common and associated with adverse effects in adulthood. The question whether these effects are observed in both genders remains controversial. A typology of antisocial behaviour that captures childhood limited (CL), adolescent onset (AO) and life course persistent behaviour (LCP) through both developmental stages is utilized to examine young adult outcomes in both sexes., Methods: The Mater-University of Queensland Study of Pregnancy (MUSP) data set is a longitudinal study following up a cohort of 7223 infants and mothers from antenatal care to the child's 21st year. Data on child antisocial behaviour was collected at ages 5 and 14 years. At the 21-year follow up, self-reported outcomes were collected on antisocial behaviour, use of alcohol, tobacco and cannabis, physical and mental health functioning. The relationship between the three antisocial sub-types and negative young adult outcomes was examined for both males and females using a series of logistic regressions., Results: Complete data across 21 years was available for 3173 participants. Males experienced higher levels of antisocial behaviour. In both males and females, AO and LCP groups exhibited elevated risk of negative outcomes including continuing antisocial behaviour, cannabis use, general health problems and depression/anxiety symptoms. The CL group exhibited poorer outcomes in physical and mental health but not in other domains., Conclusion: Both males and females exhibiting AO and LCP antisocial behaviour are at increased risk of serious adverse outcomes in young adulthood. The significant loss to follow up of high-risk groups suggests the important relationship between early antisocial behaviour and problems in adulthood have been underestimated. Further research is required to understand antisocial behaviour in adolescence, identify factors that reinforce its continuity into adulthood, and identify interventions which are able to modify adult outcomes.

Purpose: To examine the impact of the timing and duration of family experiences of poverty over the child/adolescent early life course on child aggressive/delinquent behavior and tobacco and alcohol consumption., Methods: Data were taken from a large scale population based birth cohort study with repeated follow-ups until 21 years after the birth. Poverty was measured during the pregnancy, 6 months, 5 years, and 14 years after the birth. Aggressive/delinquent behavior was measured at 14- and 21-year follow-ups. Tobacco and alcohol consumption were measured at the 21-year follow-up., Results: In multivariate analysis, family poverty experienced at the 14-year follow-up predicted persistent aggressive/delinquent behavior as well as smoking and higher levels of alcohol consumption at the 21-year follow-up. However, the strongest associations were for recurrent experiences of family poverty, with the group that experienced repeated poverty (3-4 times) being more than twice more likely to be aggressive/delinquent at both 14 and 21 years, and to drink more than one glass of alcohol per day at 21 years., Conclusions: Repeated experiences of poverty in early childhood and adolescence are strongly associated with a number of negative health-related behavior outcomes. Experience of poverty in the early adolescence seems to be the most sensitive period for such exposure., (Copyright 2010. Published by Elsevier Inc.)

Aims: To examine whether self-reporting a later stage of pubertal development in early adolescence predicts young adults' use of illicit drugs., Design: Population-based prospective birth cohort study., Setting: Follow-up of a cohort of mothers and their children, recruited between 1981 and 1983., Participants: Cohort of 2710 young adults who completed a self-report questionnaire about their use of cannabis and amphetamines at the 21-year follow-up., Measurements: Young adults' use of cannabis and amphetamines were measured at the 21-year follow-up. Stage of pubertal development was assessed at the 14-year follow-up. Potential confounding and mediating variables were assessed between birth and when the child was 14 years., Findings: Of 2,710 young adults, 49.9% (47.3 females and 52.7% males) reported that they had used cannabis and 21.0% (18.9% females and 23.3% males) reported that they had used amphetamines and cannabis by 21 years. In multivariate analyses, adolescents with a later stage of puberty were more likely to use cannabis or amphetamines in young adulthood. This association was not confounded by mother's education or child's gender and age. Part of the relationship was explained by the higher frequency of child externalizing behaviour at 14 years., Conclusions: The findings warrant further attention to puberty as a sensitive period in an individual's development. With regard to prevention, there is a need to understand more about the pathways between pubertal development, child behaviour problems and substance use.

This study examined the association between age of onset and persistence of externalizing behavior and young adults' cannabis use disorders (CUDs). Data were from a 21 year follow-up of a birth cohort study in Brisbane, Australia. The present cohort consisted of 2225 young adults who had data available about CUDs at 21 years and externalizing behavior at 5 and 14 years. Young adults' CUDs were assessed using the CIDI-Auto. Child and adolescent externalizing behavior were assessed at the 5- and 14-year phases of the study. After controlling for confounding variables, children who had externalizing behavior at both 5 and 14 years (child-onset-persistent) (COP) had a substantial increase in risk of CUD at age 21 years (Odds ratio (OR)=2.5; 95% CI: 1.5, 4.2). This association was similar for those who had 'adolescent onset' (AO) externalizing behavior. However, there was no association between 'childhood limited' (CL) externalizing behavior and CUD. Externalizing behavior in adolescence is a strong predictor of subsequent CUD. Smoking and drinking at 14 years partially mediated the link between externalizing behavior and CUD.

Objective: This investigation utilizes data from an Australian longitudinal study to identify early risk factors for adolescent antisocial behaviour., Method: Analyses are based on data from the Mater University Study of Pregnancy, an on-going longitudinal investigation of women's and children's health and development involving over 8000 participants. Five types of risk factors (child characteristics, perinatal factors, maternal/familial characteristics, maternal pre- and post-natal substance use and parenting practices) were included in analyses and were based on maternal reports, child assessments and medical records. Adolescent antisocial behaviour was measured when children were 14 years old, using the delinquency subscale of the Child Behaviour Checklist., Results: Based on a series of logistic regression models, significant risk factors for adolescent antisocial behaviour included children's prior problem behaviour (i.e. aggression and attention/restlessness problems at age 5 years) and marital instability, which doubled or tripled the odds of antisocial behaviour. Perinatal factors, maternal substance use, and parenting practices were relatively poor predictors of antisocial behaviour., Conclusions: Few studies have assessed early predictors of antisocial behaviour in Australia and the current results can be used to inform prevention programs that target risk factors likely to lead to problem outcomes for Australian youth.
