Abstract: Maternal psychological distress and mother-infant bonding problems each predict poorer offspring outcomes. They are also related to each other, yet the extensive literature reporting their association has not been meta-analysed. We searched MEDLINE, PsycINFO, CINAHL, Embase, ProQuest DTG, and OATD for English-language peer-reviewed and grey literature reporting an association between mother-infant bonding, and multiple indicators of maternal psychological distress. We included 133 studies representing 118 s les 99 s les (110,968 mothers) were eligible for meta-analysis. Results showed concurrent associations across a range of timepoints during the first year postpartum, between bonding problems and depression ( r = .27 [95% CI 0.20, 0.35] to r = .47 [95% CI 0.41, 0.53]), anxiety ( r = .27 [95% CI 0.24, 0.31] to r = .39 [95% CI 0.15, 0.59]), and stress ( r = .46 [95% CI 0.40, 0.52]). Associations between antenatal distress and subsequent postpartum bonding problems were mostly weaker and with wider confidence intervals: depression ( r = .20 [95% CI 0.14, 0.50] to r = .25 [95% CI 0.64, 0.85]), anxiety ( r = .16 [95% CI 0.10, 0.22]), and stress ( r = .15 [95% CI − 0.67, 0.80]). Pre-conception depression and anxiety were associated with postpartum bonding problems ( r = − 0.17 [95% CI − 0.22, − 0.11]). Maternal psychological distress is associated with postpartum mother-infant bonding problems. Co-occurrence of psychological distress and bonding problems is common, but should not be assumed. There may be benefit in augmenting existing perinatal screening programs with well-validated mother-infant bonding measures.

Abstract: Purpose: The Australian Temperament Project Generation 3 Cohort (ATPG3) was established to examine the extent to which offspring social and emotional development is shaped in the decades prior to conception, in parent and grandparent histories of psychosocial adjustment (e.g., emotional regulation, relationship quality and prosociality) and maladjustment (e.g., depressive symptoms, substance use and antisociality). Participants: The Australian Temperament Project (ATP) commenced in 1983 as a population representative survey of the social and emotional health of 2443 young Australians (Generation 2: 4-8 months) and their parents (Generation 1). Since then, families have been followed from infancy to young adulthood (15 waves). Between 2012 and 2018, the cohort was screened biannually for pregnancies and infants (Generation 3). Assessments were conducted in the third trimester of pregnancy, and at 8 weeks and 1 year postpartum. Findings to date: 1167 offspring (607 female) born to 703 ATP G2 parents (400 mothers) were recruited into the ATPG3 Cohort. Findings to date highlight: (1) strong continuities in depressive symptoms and substance use from adolescence through to becoming a parent (2) a role for persistent preconception mental health problems in risk for parent-child bonding difficulties, as well as infant emotional reactivity and behaviour problems (3) the importance of secure attachments in adolescence in reducing long term risk for postpartum mental health problems and (4) the protective nature of perceived social support, both preconception and postpartum, in strengthening relationship quality and social support during the COVID-19 pandemic. Future Plans: Assessments of the ATPG3 cohort in preschool and middle childhood are currently funded and underway. We intend to maintain the offspring cohort through childhood, adolescence, young adulthood and into parenthood. Data will be used to map preconception determinants of emotional health, and enhance approaches to population monitoring and targeted intervention over the life course and across generations.

Abstract: Background: Modelling trajectories of substance use over time is complex and requires judicious choices from a number of modelling approaches. In this study we examine the relative strengths and weakness of latent curve models (LCM), growth mixture modelling (GMM), and latent class growth analysis (LCGA). Design: Data were drawn from the Australian Temperament Project, a 36-year-old community-based longitudinal study that has followed a s le of young Australians from infancy to adulthood across 16 waves of follow-up since 1983. Models were fitted on past month alcohol use (n=1468) and cannabis use (n=549) across six waves of data collected from age 13-14 to 27-28 years. Findings: Of the three model types, GMMs were the best fit. However, these models were limited given the variance of numerous growth parameters had to be constrained to zero. Additionally, both the GMM and LCGA solutions had low entropy. The negative binomial LCMs provided a relatively well-fitting solution with fewer drawbacks in terms of growth parameter estimation and entropy issues. In all cases, model fit was enhanced when using a negative binomial distribution. Conclusions: Substance use researchers would benefit from adopting a complimentary framework by exploring both LCMs and mixture approaches, in light of the relative strengths and weaknesses as identified. Additionally, the distribution of data should inform modelling decisions.

Abstract: There is increasing evidence that parental determinants of offspring early life development begin well before pregnancy. We established the Victorian Intergenerational Health Cohort Study (VIHCS) to examine the contributions of parental mental health, substance use, and socio-economic characteristics before pregnancy to child emotional, physical, social, and cognitive development. Men and women were recruited from the Victorian Adolescent Health Cohort (VAHCS), an existing cohort study beginning in 1992 that assessed a representative s le of 1943 secondary school students in Victoria, Australia, repeatedly from adolescence (wave 1, mean age 14 years) to adulthood (wave 10, mean age 35 years). Victorian Adolescent Health Cohort participants with children born between 2006 and 2013 were recruited to VIHCS and invited to participate during trimester three, at 2 months postpartum, and 1 year postpartum. Parental mental health, substance use and socio-economic characteristics were assessed repeatedly throughout infant characteristics were assessed postnatally and in infancy. Data will be supplemented by linkage to routine datasets. A further follow-up is underway as children reach 8 years of age. Of the 1307 infants born to VAHCS participants between 2006 and 2013, 1030 were recruited to VIHCS. At VIHCS study entry, 18% of recruited parents had preconception common mental disorder in adolescence and young adulthood, 18% smoked daily in adolescence and young adulthood, and 6% had not completed high school. Half of VIHCS infants were female (48%), 4% were from multiple births, and 7% were preterm (<37 weeks' gestation). Victorian Intergenerational Health Cohort Study is a prospective cohort of 1030 children with up to nine waves of preconception parental data and three waves of perinatal parental and infant data. These will allow examination of continuities of parental health and health risks from the decades before pregnancy to offspring childhood, and the contributions of exposures before pregnancy to offspring outcomes in childhood.

Abstract: Aims: To explore the process of applying counterfactual thinking in examining causal predictors of substance use trajectories in observational cohort data. Specifically, we examine the extent to which quality of the parent-adolescent relationship and affiliations with deviant peers are causally related to trajectories of alcohol, tobacco, and cannabis use across adolescence and into young adulthood. Methods: Data were drawn from the Australian Temperament Project, a population-based cohort study that has followed a s le of young Australians from infancy to adulthood since 1983. Parent-adolescent relationship quality and deviant peer affiliations were assessed at age 13-14 years. Latent curve models were fitted for past month alcohol, tobacco, and cannabis use (n = 1,590) from age 15-16 to 27-28 years (5 waves). Confounding factors were selected in line with the counterfactual framework. Results: Following confounder adjustment, higher quality parent-adolescent relationships were associated with lower baseline cannabis use, but not alcohol or tobacco use trajectories. In contrast, affiliations with deviant peers were associated with higher baseline binge drinking, tobacco, and cannabis use, and an earlier peak in the cannabis use trajectory. Conclusions: Confounding adjustments weakened several estimated associations and the interpretation of such associations as causal is not without limitations. Nevertheless, findings suggested causal effects of both parent-adolescent relationships and deviant peer affiliations on the trajectory of substance use. Causal effects were however more pervasive (i.e., more substance types) and protracted for deviant peer affiliations. The current study encourages the exploration of causal relationships in observational cohort data, when relevant limitations are transparently acknowledged.

Abstract: In extending work on early life antecedents of parenting, we investigate associations between childhood family history of disadvantage, adolescent socioemotional wellbeing, and age at first parenthood and subsequent parenting behaviour. Parent‐child interactions were recorded when participants in the longitudinal Dunedin Multidisciplinary Health and Development Study (New Zealand) had a three‐year‐old child. Data were available for 358 mothers and 321 fathers, aged between 17.7 and 41.5 at the time of their child's birth. Associations between parenting and antecedent data on socioeconomic disadvantage, adolescent wellbeing and mental health, as well as current adult mental health and age at parenting, were tested for using structural equation modelling. Family disadvantage in childhood and lower adolescent wellbeing was associated with less positive future parenting, but only adult (not adolescent) anxiety/depression symptoms were directly associated with parenting behaviour. Childhood family disadvantage was associated with further disadvantage across the life course that included less positive parenting of the next generation. In contrast, socioemotional wellbeing during adolescence and later age of onset of parenting were associated with more positive parenting. Reducing childhood disadvantage and improving socioemotional wellbeing during childhood and adolescence is likely to have intergenerational benefits through better parenting of the next generation.

Abstract: Most but not all adults become parents, yet it remains unclear which characteristics indicate an orientation toward parenting. The aims of this study were to (a) distinguish profiles of in idual and interpersonal resources in young adults that may orient them toward parenthood and (b) investigate whether profiles predicted timing of entering parenthood, postpartum parenting behavior, and parent-infant bonding. Participants were 1,429 young people (53% female) enrolled in an Australian 39-year longitudinal study. Predictor data for latent profile analysis were collected at 23-24 and 27-28 years. Parenthood timing was designated as "early" ≤ 25 years, "on-time" > 25 years, and "not a parent" by age 37 years. Parenting outcomes were assessed at 12 months postpartum in 684 parents of 1,144 children. Four-profile classes were identified: "connected" (

Abstract: The relative contributions of cannabis and alcohol use to educational outcomes are unclear. We examined the extent to which adolescent cannabis or alcohol use predicts educational attainment in emerging adulthood. Participant-level data were integrated from three longitudinal studies from Australia and New Zealand (Australian Temperament Project, Christchurch Health and Development Study, and Victorian Adolescent Health Cohort Study). The number of participants varied by analysis (N=2179-3678) and were assessed on multiple occasions between ages 13 and 25. We described the association between frequency of cannabis or alcohol use prior to age 17 and high school non-completion, university non-enrolment, and degree non-attainment by age 25. Two other measures of alcohol use in adolescence were also examined. After covariate adjustment using a propensity score approach, adolescent cannabis use (weekly+) was associated with 1½ to two-fold increases in the odds of high school non-completion (OR=1.60, 95% CI=1.09-2.35), university non-enrolment (OR=1.51, 95% CI=1.06-2.13), and degree non-attainment (OR=1.96, 95% CI=1.36-2.81). In contrast, adjusted associations for all measures of adolescent alcohol use were inconsistent and weaker. Attributable risk estimates indicated adolescent cannabis use accounted for a greater proportion of the overall rate of non-progression with formal education than adolescent alcohol use. Findings are important to the debate about the relative harms of cannabis and alcohol use. Adolescent cannabis use is a better marker of lower educational attainment than adolescent alcohol use and identifies an important target population for preventive intervention.

Abstract: There is increasing evidence that the life-course origins of health and development begin before conception. We examined associations between timing and frequency of preconception cannabis and tobacco use and next generation preterm birth (PTB), low birth weight (LBW) and small for gestational age. 665 participants in a general population cohort were repeatedly assessed on tobacco and cannabis use between ages 14–29 years, before pregnancy. Associations were estimated using logistic regression. Preconception parent (either maternal or paternal) daily cannabis use age 15–17 was associated with sixfold increases in the odds of offspring PTB (aOR 6.65, 95% CI 1.92, 23.09), and offspring LBW (aOR 5.84, 95% CI 1.70–20.08), after adjusting for baseline sociodemographic factors, parent sex, offspring sex, family socioeconomic status, parent mental health at baseline, and concurrent tobacco use. There was little evidence of associations with preconception parental cannabis use at other ages or preconception parental tobacco use. Findings support the hypothesis that the early life origins of growth begin before conception and provide a compelling rationale for prevention of frequent use during adolescence. This is pertinent given liberalisation of cannabis policy.

Abstract: Prior anxiety and depression have been identified as risk factors for maternal perinatal mental health problems, but other preconception mental disorders have not been prospectively examined. This study investigated prospectively whether women with preconception personality disorder have increased rates of antenatal anxiety and/or depressive symptoms. 244 women in a population cohort were assessed for personality disorder at age 24 using the Standardised Assessment of Personality. Five to twelve years later, women were screened with the Clinical Interview Schedule, Revised Anxiety Subscale and the Edinburgh Postnatal Depression Scale during the third trimester of 328 pregnancies. Preconception personality disorder was associated with a three-fold increase in the odds of antenatal anxiety symptoms, which remained with adjustment for preconception background factors and preconception common mental disorder (adjusted OR 2.84, 95% CI 1.31-6.15). Preconception personality disorder was associated with doubled odds of antenatal depressive symptoms, however this was attenuated with adjustment for preconception background factors and preconception common mental disorder (adjusted OR 1.98, 95% CI 0.81-4.81). Our findings are restricted to pregnant women aged 29-35 years. Anxiety and depression may have been under-identified because they were assessed at a single antenatal time point. Residual confounding of the associations by preconception common mental disorder at other time points may have occurred. Women with personality disorder are at heightened risk of anxiety symptoms in pregnancy, over and above risks associated with prior common mental disorder. This raises a possibility that pregnancy brings particular emotional challenges for women with personality disorders.

Abstract: The timing and sequencing of completing education, leaving home, beginning full-time work, forming intimate relationships, and parenting are evolving rapidly worldwide. This study describes patterns of transition in a population-based longitudinal study of Australians at ages 20 and 29 ( N = 1,366). Latent class analysis and latent transition analysis identified four categories of emerging adulthood in both age-groups. At age 20, 41.8% were in the category of students living in their parents’ home at age 29, most were categorized as “established young adults” with (25.7%) or without children (51.1%). A majority of “young independents” at age 20 went on to become “established parents” at 29, and most students living independently at age 20 were “established young adults without children” at 29. Findings suggest that the directions of emerging adulthood are largely set in place by age 20. Programs and policies may be needed to support transitions into stable life partnerships and parenthood.

Abstract: Maternal internalizing symptoms during pregnancy, specifically depression and/or anxiety, are commonly linked to negative affectivity (NA) in infant offspring. These links are commonly attributed to biological effects of the in utero environment on fetal development. However, research suggests that internalizing symptoms before and after pregnancy, as well as in fathers, may also be associated with NA in infant offspring. Such findings suggest greater complexity in transmission than can be explained by biological in utero programming alone. Further, infant NA is often treated as an homogenous construct, yet it covers a range of facets including fear, frustration, sadness, and slow recovery from distress that may each be differentially associated with parent internalizing distress. Here we aimed to (1) meta-analytically quantify associations between maternal and paternal internalizing symptoms and infant offspring NA, (2) examine how associations varied as a function of distinct phenotypic facets of NA, and (3) examine how associations varied by timing of parental symptoms (preconception, antenatal, postnatal) and infant age. Using random-effects meta-analysis, we found that maternal internalizing symptoms were positively associated with infant NA (r = 0.17 [95% CI 0.14, 0.21], 42 studies, 149 estimates). Preliminary evidence from studies of fathers likewise suggested a positive association with infant NA (r = 0.13 [95% CI 0.04, 0.22], 6 studies, 40 estimates). We observed associations with the global infant NA construct, as well as effect modification by infant NA facet (maternal r range .12 to .22 paternal r range .03 to.21). In mothers, there was no evidence of effect modification by timing of internalizing symptoms or infant age in fathers, preliminary associations were larger for postnatal than antenatal symptoms. Further studies of preconception and paternal symptoms are now needed, and we suggest avenues for research to advance understanding of the relations between parent internalizing symptoms and infant NA.

Abstract: Alcohol consumption is common in adolescence and young adulthood and may continue into pregnancy, posing serious risk to early fetal development. We examine the frequency of periconception alcohol use (prior to pregnancy awareness) and the extent to which adolescent and young adult alcohol use prospectively predict periconception use. A longitudinal, population‐based study. Victoria, Australia. A total of 289 women in trimester three of pregnancy (age 29–35 years 388 pregnancies). The main exposures were binge [≥ 4.0 standard drinks (SDs)/day] and frequent (≥ 3 days/week) drinking in adolescence (mean age = 14.9–17.4 years) and young adulthood (mean age 20.7–29.1 years). Outcomes were frequency (≥ 3 days/week, ≥ monthly, never) and quantity (≥ 4.0 SDs, ≥ 0.5 and 4.0 SDs, none) of periconception drinking. Alcohol use was common in young adulthood prior to pregnancy (72%) and in the early weeks of pregnancy (76%). The proportions drinking on most days and binge drinking were similar at both points. Reflecting a high degree of continuity in alcohol use behaviours, most women who drank periconceptionally had an earlier history of frequent (77%) and/or binge (85%) drinking throughout the adolescent or young adult years. Young adult binge drinking prospectively predicted periconception drinking quantity [odds ratio (OR) = 3.7, 95% confidence interval (CI) = 1.9–7.4], compared with women with no prior history. Similarly, frequent young adult drinking prospectively predicted frequent periconception drinking (OR = 30.7, 95% CI = 12.3–76.7). Women who engage in risky (i.e. frequent and binge) drinking in their adolescent and young adult years are more likely to report risky drinking in early pregnancy prior to pregnancy recognition than women with no prior history of risky drinking.

Abstract: The Australian New Zealand Intergenerational Cohort Consortium (ANZ-ICC) brings together three of the longest running intergenerational cohort studies in Australia and New Zealand to examine the extent to which preconception parental life histories (from infancy to parenthood) predict next generation early health and development. The aims are threefold: (1) to describe pathways of advantage that strengthen emotional health and well-being from one generation to the next, (2) to describe pathways of disadvantage that perpetuate cycles of emotional and behavioural problems across generations, and (3) to identify modifiable factors capable of breaking intergenerational cycles. The Victorian Intergenerational Health Cohort Study has followed 1,943 young Australians from adolescence to adulthood across ten waves since 1992, and 1,030 offspring from pregnancy to early childhood since 2006. The Australian Temperament Project Generation 3 Study has followed 2,443 young Australians from infancy to adulthood across 15 waves since 1983, and 1170 offspring from pregnancy to early childhood since 2012. The Dunedin Multidisciplinary Health and Development Study Parenting Study has followed 1,037 young New Zealanders across 15 waves since 1972, and 730 offspring in early childhood since 1994. Cross-cohort replication analyses will be conducted for common preconception exposures and next generation offspring outcomes, while integrated data analysis of pooled data will be used for rare exposures and outcomes. The ANZ-ICC represents a unique collaboration that bridges the disciplines of lifecourse epidemiology, biostatistics, developmental psychology and psychiatry, to study the role of parental preconception exposures on next generation health and development.

Abstract: Rates of common mental health problems (depression/anxiety) rise sharply in adolescence and peak in young adulthood, often coinciding with the transition to parenthood. Little is known regarding the persistence of common mental health problems from adolescence to the perinatal period in both mothers and fathers. A total of 393 mothers (686 pregnancies) and 257 fathers (357 pregnancies) from the intergenerational Australian Temperament Project Generation 3 Study completed self-report assessments of depression and anxiety in adolescence (ages 13–14, 15–16, 17–18 years) and young adulthood (ages 19–20, 23–24, 27–28 years). The Edinburgh Postnatal Depression Scale was used to assess depressive symptoms at 32 weeks pregnancy and 12 months postpartum in mothers, and at 12 months postpartum in fathers. Most pregnancies (81%) in which mothers reported perinatal depression were preceded by a history of mental health problems in adolescence or young adulthood. Similarly, most pregnancies (83%) in which fathers reported postnatal depression were preceded by a preconception history of mental health problems. After adjustment for potential confounders, the odds of self-reporting perinatal depression in both women and men were consistently higher in those with a history of persistent mental health problems across adolescence and young adulthood than those without (OR women 5.7, 95% CI 2.9–10.9 OR men 5.5, 95% CI 1.03–29.70). Perinatal depression, for the majority of parents, is a continuation of mental health problems with onsets well before pregnancy. Strategies to promote good perinatal mental health should start before parenthood and include both men and women.

Abstract: Background: When adolescent boys experience close, secure relationships with their parents and peers, the implications are potentially far reaching, including lower levels of mental health problems in adolescence and young adulthood. Here we use rare prospective intergenerational data to extend our understanding of the impact of adolescent attachments on subsequent postpartum mental health problems in early fatherhood. Methods: At age 17–18 years, we used an abbreviated Inventory of Parent and Peer Attachment to assess trust, communication, and alienation reported by 270 male participants in their relationships with mothers, fathers, and peers. More than a decade later, we assessed the adult males, now fathers, at 12 months postpartum ( N = 409 infant offspring) for symptoms of depression, anxiety, and stress. Logistic regression was used to examine the extent to which attachment dimensions predicted paternal postpartum mental health, adjusting for potential confounding, and with assessment for interactions between parent and peer attachments. Results: Trust in mothers and peers, and good communication with fathers during adolescence, were associated with 5 to 7 percentage point reductions in postpartum mental health symptoms in early fatherhood. Weak evidence of parent-peer interactions suggested secure attachments with either parent or peer may compensate for an insecure attachment with the other. Conclusions: Our results suggest that fostering trust and communication in relationships that adolescent boys have with parents and peers may have substantial effects on rates of paternal postpartum mental health problems. The protective benefits may be preventative in intergenerational cycles of risk for mental health problems.

Abstract: To determine the extent to which the transition to parenthood protects against heavy and problematic alcohol consumption in young men and women. Integrated participant-level data analysis from three population-based prospective Australasian cohort studies. General community participants from the Australian Temperament Study, the Christchurch Health and Development Study, and the Victorian Adolescent Health Cohort Study. Recent binge drinking, alcohol abuse/dependence and number of standard drinks consumed per occasion. 4015 participants (2151 females 54%) were assessed on four occasions between ages 21 and 35. Compared to women with children aged <12 months, women who had not transitioned to parenthood were more likely to meet the criteria for alcohol abuse/dependence (fully adjusted risk ratio [RR] 3.5 95% CI 1.5-7.9) and to report recent binge drinking (RR 3.0 95% CI 2.1-4.3). The proportion of women meeting the criteria for alcohol abuse/dependence and/or binge drinking increased with the age of participants' youngest child, as did the mean number of standard drinks consumed on each occasion (1.8 if the youngest child was <1 year of age vs. 3.6 for 5+ years of age). Associations between parenthood and male drinking behaviour were considerably weaker. For most women in their twenties and thirties, parenting a child <1 year of age was associated with reduced alcohol consumption. However, this protective effect diminished after 12 months with drinking levels close to pre-parenthood levels after five years. There was little change in male drinking with the transition to parenthood.

Abstract: This study assessed the extent to which women's preconception binge drinking, tobacco use and cannabis use, reported prospectively in adolescence and young adulthood, predicted use of these substances during pregnancy and at 1 year postpartum. Data were pooled from two intergenerational cohort studies: the Australian Temperament Project Generation 3 Study (395 mothers, 691 pregnancies) and the Victorian Intergenerational Health Cohort Study (398 mothers, 609 pregnancies). Alcohol, tobacco and cannabis use were assessed in adolescence (13–18 years), young adulthood (19–29 years) and at ages 29–35 years for those transitioning to parenthood. Exposures were weekly or more frequent preconception binge drinking (5 + drinks in one session), tobacco use and cannabis use. Outcomes were any alcohol, tobacco and cannabis use prior to awareness of the pregnancy, after awareness of pregnancy (up to and including the third trimester pregnancy) and at 1 year postpartum. Frequent preconception binge drinking, tobacco use and cannabis use across both adolescence and young adulthood were strong predictors of continued use post-conception, before and after awareness of the pregnancy and at 1 year postpartum. Substance use limited to young adulthood also predicted continued use post-conception. Persistent alcohol, tobacco use and cannabis use that starts in adolescence has a strong continuity into parenthood. Reducing substance use in the perinatal period requires action well before pregnancy, commencing in adolescence and continuing into the years before conception and throughout the perinatal period.

Abstract: Maternal mental health during pregnancy and postpartum predicts later emotional and behavioural problems in children. Even though most perinatal mental health problems begin before pregnancy, the consequences of preconception maternal mental health for children's early emotional development have not been prospectively studied. We used data from two prospective Australian intergenerational cohorts, with 756 women assessed repeatedly for mental health problems before pregnancy between age 13 and 29 years, and during pregnancy and at 1 year postpartum for 1231 subsequent pregnancies. Offspring infant emotional reactivity, an early indicator of differential sensitivity denoting increased risk of emotional problems under adversity, was assessed at 1 year postpartum. Thirty-seven percent of infants born to mothers with persistent preconception mental health problems were categorised as high in emotional reactivity, compared to 23% born to mothers without preconception history (adjusted OR 2.1, 95% CI 1.4–3.1). Ante- and postnatal maternal depressive symptoms were similarly associated with infant emotional reactivity, but these perinatal associations reduced somewhat after adjustment for prior exposure. Causal mediation analysis further showed that 88% of the preconception risk was a direct effect, not mediated by perinatal exposure. Maternal preconception mental health problems predict infant emotional reactivity, independently of maternal perinatal mental health while associations between perinatal depressive symptoms and infant reactivity are partially explained by prior exposure. Findings suggest that processes shaping early vulnerability for later mental disorders arise well before conception. There is an emerging case for expanding developmental theories and trialling preventive interventions in the years before pregnancy.

Abstract: Background: The COVID-19 pandemic has placed considerable pressure on families, testing the quality of relationships and the strength of social support within and beyond the family network. However, little is known about the pre-pandemic factors that predict family relational resilience and social functioning during times of natural disaster or global crisis. Here we use data from one of Australia's longest running studies of social and emotional development to examine the nature and timing of possible relational and social support intervention aimed at preparing families for future adversities. Methods: Data were from the Australian Temperament Project Generation 3 (ATPG3) Study, a population representative three generation cohort study of families established in 1983. A subset of Generation 2 parents completed a COVID-19 specific survey in May-September 2020 (502 parents of 871 children 60% mothers 37–38 years). These participants had completed the Quality of Relationships Inventory to assess social support during young adulthood, at 23–24 years (2006) and 27–28 years (2010), before next generation conception. Participants had also completed the Maternity Social Support Scale 1 year postpartum for each child born across the ATPG3 assessment period (2012–2019). In 2020, during the height of the Australian lockdowns, participants rated the quality of their relationships with their partners, children and broader family and friends, in addition to social support within and extended beyond their family. Results: Pre-pandemic partner support was associated with partner relationship quality during the pandemic (β = 0.22). Pre-pandemic support from friends was associated with relationship quality with other family and friends during the pandemic (β = 0.12 – 0.18). Pre-pandemic support (from partner, family and friends) was consistently associated with social support within families during the pandemic (β = 0.11 – 0.21). Pre-pandemic support from friends was also associated with family support extended to others within their local community during the pandemic (β = 0.12 – 0.13). Conclusions: Strengthening supportive relationships during major life transitions, prior to the start of family life and in early parenthood, may have long-term and intergenerational benefits years into the future for both families and communities. This may promote resilience during future crises and other more normative stressful life events.

Abstract: Adolescent growth and social development shape the early development of offspring from preconception through to the post-partum period through distinct processes in males and females. At a time of great change in the forces shaping adolescence, including the timing of parenthood, investments in today’s adolescents, the largest cohort in human history, will yield great idends for future generations.

Abstract: The purpose of this study was to examine the extent to which adolescent bonding problems with parents predict next-generation maternal-infant bonding problems at 2 and 12 months postpartum. Data were from a two-generation prospective cohort study of 1026 offspring (3 perinatal waves) born to participants of a two-decade (10-wave) study of 1943 adolescents. Dyads in this analysis were 395 mothers (29-36 years) of 606 offspring (305 female). At 16 years, we assessed adolescents' perceptions of their mother's and father's care and control, separately and in combination. Subsequently, when participants were adult mothers of infants 2 and 12 months postpartum, we assessed impaired maternal-infant bonding, infant-directed rejection-anger, and caregiving anxiety. Adolescent-parent bonding problems were strongly predictive of women's subsequent bonding problems with infants. In particular, impaired postpartum maternal bonding was predicted by adolescent reports of low paternal care (12 months: OR=3.1, 95% CI 1.1-8.6) and high maternal control (12 months: OR=3.7, 95% CI 1.4-9.7). In combination, high maternal control and low paternal control also predicted impaired postpartum bonding (2 months: OR=5.0, 95% CI 1.3-20 12 months: OR=12, 2.6-56), caregiving anxiety (2 months: OR=4, 95% CI 1.5-11 12 months: OR=8.8, 95% CI 1.8-43), and rejection/anger (12 months: OR=4.1, 95% CI 1.0-16). Further combinations of care and overprotection that significantly predicted postpartum bonding problems are presented. Our results indicate that adolescent girls who experience high maternal control and low paternal care are at higher risk for subsequent maternal-infant bonding problems. The strength of associations suggests that interventions should begin well before pregnancy.

Abstract: We examined prospective associations between men's common mental disorders in the decades prior to offspring conception and subsequent paternal antenatal mental health problems. Data came from a prospective intergenerational cohort study which assessed common mental disorder nine times from age 14 to 29 years, and in the third trimester of subsequent pregnancies to age 35 years ( N = 295 pregnancies to 214 men). Men with histories of adolescent and young adult common mental disorders were over four times more likely to experience antenatal mental health problems. Future research identifying modifiable perinatal factors that counteract preconception risk would provide further targets for intervention. None.

Abstract: There has been interest in the antecedents and mental health impacts of eating and body image disturbances in adolescence. Less is known about longer‐term mental health impacts into young adulthood, as longitudinal studies with data spanning this developmental period are rare. We capitalize on mental health data collected across adolescence and young adulthood from a population‐based cohort study that has been following Australian children and their families from infancy to young adulthood. This s le comprised 1,568 participants who completed the Eating Disorder Inventory drive for thinness and bulimic behavior (the severity of binge‐purge patterns) subscales, and a modified version of the body dissatisfaction subscale in mid‐adolescence (15–16 years), or the Depression Anxiety Stress Scales in young adulthood (19–20, 23–24, and 27–28 years). After adjusting for baseline demographic and prior mental health factors ( years of age), all three indices of eating and body image disturbances in adolescence predicted each mental health outcome in young adulthood. Mental health risks associated with adolescent body dissatisfaction and bulimic behavior scores remained stable across young adulthood, with men having more pronounced problems associated with bulimic behavior scores than women. In contrast, mental health risks associated with adolescent drive for thinness scores diminished across this period similarly for men and women. Findings suggest that adolescent eating and body image disturbances may have long‐term mental health impacts that extend into young adulthood. This underscores the need for early preventative intervention, and longer‐term monitoring and support for body image and eating disturbances.

Abstract: Postnatal depression (PND) is common and predicts a range of adverse maternal and offspring outcomes. PND rates are highest among women with persistent mental health problems before pregnancy, and antenatal healthcare provides ideal opportunity to intervene. We examined antenatal perceived social support as a potential intervention target in preventing PND symptoms among women with prior mental health problems. A total of 398 Australian women (600 pregnancies) were assessed repeatedly for mental health problems before pregnancy (ages 14–29 years, 1992–2006), and again during pregnancy, two months postpartum and one year postpartum (2006–2014). Causal mediation analysis found that intervention on perceived antenatal social support has the potential to reduce rates of PND symptoms by up to 3% (from 15 to 12%) in women with persistent preconception symptoms. Supplementary analyses found that the role of low antenatal social support was independent of concurrent antenatal depressive symptoms. Combined, these two factors mediated up to more than half of the association between preconception mental health problems and PND symptoms. Trialling dual interventions on antenatal depressive symptoms and perceived social support represents one promising strategy to prevent PND in women with persistent preconception symptoms. Interventions promoting mental health before pregnancy may yield an even greater reduction in PND symptoms by disrupting a developmental cascade of risks via these and other pathways. This article is part of the theme issue ‘Multidisciplinary perspectives on social support and maternal–child health’.

Abstract: This study examined whether positive development (PD) in adolescence and young adulthood predicts offspring behavior in two Australasian intergenerational cohorts. The Australian Temperament Project Generation 3 Study assessed PD at age 19–28 (years 2002–2010) and behavior in 1165 infants (12–18 months 608 girls) of 694 Australian‐born parents (age 29–35 2012–2019 399 mothers). The Dunedin Multidisciplinary Health and Development Parenting Study assessed PD at age 15–18 (years 1987–1991) and behavior in 695 preschoolers (3–5 years 349 girls) and their New Zealand born parents (age 21–46 1994–2018 363 mothers 89% European ethnicity). In both cohorts, PD before parenthood predicted more positive offspring behavior ( β range = .11–.16) and fewer behavior problems ( β range = −.09 to −.11). Promoting strengths may secure a healthy start to life.

Abstract: Modelling trajectories of substance use over time is complex and requires judicious choices from a number of modelling approaches. In this study we examine the relative strengths and weakness of latent curve models (LCM), growth mixture modelling (GMM), and latent class growth analysis (LCGA). Data were drawn from the Australian Temperament Project, a 36-year-old community-based longitudinal study that has followed a s le of young Australians from infancy to adulthood across 16 waves of follow-up since 1983. Models were fitted on past month alcohol use (n = 1468) and cannabis use (n = 549) across six waves of data collected from age 13-14 to 27-28 years. Of the three model types, GMMs were the best fit. However, these models were limited given the variance of numerous growth parameters had to be constrained to zero. Additionally, both the GMM and LCGA solutions had low entropy. The negative binomial LCMs provided a relatively well-fitting solution with fewer drawbacks in terms of growth parameter estimation and entropy issues. In all cases, model fit was enhanced when using a negative binomial distribution. Substance use researchers would benefit from adopting a complimentary framework by exploring both LCMs and mixture approaches, in light of the relative strengths and weaknesses as identified. Additionally, the distribution of data should inform modelling decisions.

Abstract: Self-harm in young people is associated with later problems in social and emotional development. However, it is unknown whether self-harm in young women continues to be a marker of vulnerability on becoming a parent. This study prospectively describes the associations between pre-conception self-harm, maternal depressive symptoms and mother–infant bonding problems. The Victorian Intergenerational Health Cohort Study (VIHCS) is a follow-up to the Victorian Adolescent Health Cohort Study (VAHCS) in Australia. Socio-demographic and health variables were assessed at 10 time-points (waves) from ages 14 to 35, including self-reported self-harm at waves 3–9. VIHCS enrolment began in 2006 (when participants were aged 28–29 years), by contacting VAHCS women every 6 months to identify pregnancies over a 7-year period. Perinatal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale during the third trimester, and 2 and 12 months postpartum. Mother–infant bonding problems were assessed with the Postpartum Bonding Questionnaire at 2 and 12 months postpartum. Five hundred sixty-four pregnancies from 384 women were included. One in 10 women (9.7%) reported pre-conception self-harm. Women who reported self-harming in young adulthood (ages 20–29) reported higher levels of perinatal depressive symptoms and mother–infant bonding problems at all perinatal time points [perinatal depressive symptoms adjusted β = 5.40, 95% confidence interval (CI) 3.42–7.39 mother–infant bonding problems adjusted β = 7.51, 95% CI 3.09–11.92]. There was no evidence that self-harm in adolescence (ages 15–17) was associated with either perinatal outcome. Self-harm during young adulthood may be an indicator of future vulnerability to perinatal mental health and mother–infant bonding problems.
