Abstract
Childhood abuse can have long-term adverse outcomes in adulthood. These outcomes may pose a particular threat to the health and well-being of perinatal women; however, to date, this body of knowledge has not been systematically collated and synthesized. This systematic review examined the child abuse literature and a broad range of perinatal outcomes using a comprehensive search strategy. The aim of this review was to provide a clearer understanding of the distinct effect of different abuse types and areas where there may be gaps in our knowledge. Following PRISMA guidelines, EBSCO, PsychInfo, Scopus, Medline, CINAHL, PubMed, and Google Scholar databases and gray literature including preprints, dissertations and theses were searched for literature where childhood abuse was associated with any adverse perinatal outcome between 1969 and 2022. Exclusion criteria included adolescent samples, abuse examined as a composite variable, editorials, letters to the editor, qualitative studies, reviews, meta-analyses, or book chapters. Using an assessment tool, two reviewers extracted and assessed the methodological quality and risk of bias of each study. From an initial 12,384 articles, 95 studies were selected, and the outcomes were categorized as pregnancy, childbirth, postnatal for the mother, and perinatal for mother and child. The prevalence of childhood abuse ranged from 5-25% with wide variability (physical 2-78%, sexual 2-47%, and emotional/psychological 2-69%). Despite some consistent findings relating to psychological outcomes (i.e., depression and PTSD), most evidence was inconclusive, effect sizes were small, or the findings based on a limited number of studies. Inconsistencies in findings stem from small sample sizes and differing methodologies, and their diversity meant studies were not suitable for a meta-analysis. Research implication include the need for more rigorous methodology and research in countries where the prevalence of abuse may be high. Policy implications include the need for trauma-informed care with the Multi-level Determinants of Perinatal Wellbeing for Child Abuse Survivors model a useful framework. This review highlights the possible impacts of childhood abuse on perinatal women and their offspring and areas of further investigation. This review was registered with PROSPERO in 2021 and funded by an internal grant from Charles Sturt University.

Abstract
Although numerous factors have been found to influence postpartum depression (PPD), no previous meta-analysis have systematically explored whether it is affected by adverse childhood experiences (ACEs). This study aimed to explore the influence of ACEs and their subtypes on PPD. A systematic literature search was conducted using Web of Science, PubMed, Embase, Wan Fang, China Science and Technology Journal Database, Chinese Biomedical Database, and China National Knowledge Infrastructure, and literature was screened according to inclusion and exclusion criteria. Methodological quality assessment and data extraction were performed on the included studies. A random-effects model was used to pool the effects. In total, 24 studies were included, and 73 independent effects were extracted from them. The meta-analysis revealed that ACE was a risk factor for PPD (odds ratio [OR] = 2.31, 95% confidence interval [CI] [2.04, 2.63]). The subgroup analysis results showed that emotional abuse was the ACE subtype most strongly related to the occurrence of PPD (OR = 2.95, 95% CI [2.08, 4.20]), followed by emotional neglect (OR = 2.87, 95% CI [1.89, 4.36]) and sexual abuse (OR = 2.81, 95% CI [1.93, 4.09]). In addition, family member incarceration (OR = 2.62, 95% CI [1.51, 4.54]), physical abuse (OR = 2.31, 95% CI [1.67, 3.19]), and physical neglect (OR = 2.15, 95% CI [1.36, 3.39]) also have strong effects on PPD. ACE is a risk factor for PPD. Early screening of ACE plays an important role in the prevention and intervention of PPD.

Abstract
BACKGROUND The association between a lifetime history of sexual victimization and the well-being of women during the perinatal period has received increasing attention. However, research investigating this relationship has yet to be systematically reviewed or quantitatively synthesized. AIM This systematic review and meta-analysis aims to calculate the pooled effect size estimate of the statistical association between a lifetime history of sexual victimization and perinatal depression (PND). METHOD Four bibliographic databases were systematically searched, and reference harvesting was conducted to identify peer-reviewed articles that empirically examined associations between a lifetime history of sexual victimization and PND. A random effects model was used to ascertain an overall pooled effect size estimate in the form of an odds ratio and corresponding 95% confidence intervals (CIs). Subgroup analyses were also conducted to assess whether particular study features and sample characteristic (e.g., race and ethnicity) influenced the magnitude of effect size estimates. RESULTS This review included 36 studies, with 45 effect size estimates available for meta-analysis. Women with a lifetime history of sexual victimization had 51% greater odds of experiencing PND relative to women with no history of sexual victimization (OR = 1.51, 95% CI [1.35, 1.67]). Effect size estimates varied considerably according to the PND instrument used in each study and the racial/ethnic composition of each sample. CONCLUSION Findings provide compelling evidence for an association between a lifetime history of sexual victimization and PND. Future research should focus on screening practices and interventions that identify and support survivors of sexual victimization perinatally.

Abstract
OBJECTIVE Investigate the association between adverse childhood experiences and pre-pregnancy body mass index (BMI) in a population-based cohort in Trøndelag county, Norway. MATERIALS AND METHODS We linked data from the third (2006-2008) or fourth (2017-2019) survey of the Trøndelag Health Study (HUNT) and the Medical Birth Registry of Norway for 6679 women. Multiple logistic regression models were used to examine the association between adverse childhood experiences and pre-pregnancy BMI. Adverse childhood experiences were self-reported in adulthood and included perceiving childhood as difficult, parental divorce, parental death, dysfunctional family environment, bad childhood memories and lack of support from a trusted adult. Pre-pregnancy BMI was derived from the Medical Birth Registry of Norway or BMI measurement from the HUNT survey conducted within 2 years prior to the woman's pregnancy. RESULTS Perceiving childhood as difficult was associated with higher odds of pre-pregnancy underweight (OR 1.78, 95%CI 0.99-3.22) and obesity (OR 1.58, 95%CI 1.14-2.2). A difficult childhood was positively associated with obesity with an adjusted OR of 1.19, 95%CI 0.79-1.81 (class I obesity), 2.32, 95%CI 1.35-4.01 (class II obesity) and 4.62, 95%CI 2.0-10.65 (class III obesity). Parental divorce was positively associated obesity (OR 1.34, 95%CI 1.10-1.63). Bad childhood memories were associated with both overweight (OR 1.34, 95%CI 1.01-1.79) and obesity (OR 1.63, 95%CI 1.13-2.34). Parental death was not associated with pre-pregnancy BMI. CONCLUSIONS Childhood adversities were associated with pre-pregnancy BMI. Our results suggest that the positive associations between childhood adversities and pre-pregnancy obesity increased with increasing obesity level.

Maternal childhood maltreatment and perinatal outcomes: A systematic review. J Affect Disord 2022; 302:139-159. [PMID: 35041871 DOI: 10.1016/j.jad.2022.01.062] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 01/10/2022] [Accepted: 01/13/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Maternal childhood maltreatment (MCM) is linked to poor perinatal outcomes but the evidence base lacks cohesion. We explore the impact of MCM on four perinatal outcome domains: pregnancy and obstetric; maternal mental health; infant; and the quality of the care-giving environment. Mechanisms identified in the included studies are discussed in relation to the maternal programming hypothesis and directions for future research. METHOD We completed a comprehensive literature search of eight electronic databases. Independent quality assessments were conducted and PRISMA protocols applied to data extraction. RESULTS Inclusion criteria was met by N = 49 studies. MCM was consistently associated with difficulties in maternal and infant emotional regulation and with disturbances in the mother-infant relationship. Directly observed and maternal-reported difficulties in the mother-infant relationship were often mediated by mothers' current symptoms of psychopathology. Direct and mediated associations between MCM and adverse pregnancy and obstetric outcomes were suggested by a limited number of studies. Emotional and sexual abuse were the most consistent MCM subtype significantly associated with adverse perinatal outcomes. LIMITATIONS A meta-analysis was not possible due to inconsistent reporting and the generally small number of studies for most perinatal outcomes. CONCLUSIONS MCM is associated with adverse perinatal outcomes for mothers' and infants. Evidence suggests these associations are mediated by disruptions to maternal emotional functioning. Future research should explore biological and psychosocial mechanisms underpinning observed associations between specific subtypes of MCM and adverse perinatal outcomes. Services have a unique opportunity to screen for MCM and detect women and infants at risk of adverse outcomes during the perinatal period.

Abstract
Childhood sexual abuse (CSA) is a common form of childhood maltreatment. Several studies have shown that CSA adversely affects the physical and mental health. Numerous studies have evaluated the prevalence of CSA among females using various instruments. In this meta-analysis, we estimated the rate of CSA among women using the short form of the Childhood Trauma Questionnaire for the first time. Four databases (PsycINFO, PubMed, Cochrane Library, and Embase) were systematically searched for studies published as of April 2, 2018. Forty-eight articles (53 groups of samples) covering 22,224 individuals, including women, from 16 countries were selected. Using the random-effects model, the pooled overall rate of CSA was 24% (95% confidence interval [21%, 27%]). On subgroup analyses, the rate of female CSA in people with mental illness was higher than that in the general group; this result showed variability among different geographical regions.

Abstract
The early stage of development is a vulnerable period for progeny neurodevelopment, altering cytogenetic and correct cerebral functionality. The exposure High-Fat Diet (HFD) is a factor that impacts the future mental health of individuals. This review analyzes possible mechanisms involved in the development of mood disorders in adulthood because of maternal HFD intake during gestation and lactation, considering previously reported findings in the last five years, both in humans and animal models. Maternal HFD could induce alterations in mood regulation, reported as increased stress response, anxiety-like behavior, and depressive-like behavior. These changes were mostly related to HPA axis dysregulations and neuroinflammatory responses. In conclusion, there could be a relationship between HFD consumption during the early stages of life and the development of psychopathologies during adulthood. These findings provide guidelines for the understanding of possible mechanisms involved in mood disorders, however, there is still a need for more human clinical studies that provide evidence to improve the understanding of maternal nutrition and future mental health outcomes in the offspring.

Abstract
BACKGROUND Maternal obesity may disrupt the developmental process of the fetus during gestation in rats. Recent evidence suggests that taurine can exert protective role against detrimental influence of obesogenic diets. This study aimed to examine the effect of maternal cafeteria diet and/or taurine supplementation on maternal dietary intake, plasma metabolites, fetal growth and development. METHODS Female Wistar rats were fed a control diet (CON), CON supplemented with 1.5% taurine in drinking water (CONT), cafeteria diet (CAF) or CAF supplemented with taurine (CAFT) from weaning. After 8 weeks all animals were mated and maintained on the same diets during pregnancy and lactation. RESULTS Dietary intakes were significantly different between the groups. Both CAF and CAFT fed dams consumed less water in comparison to CON and CONT dams. Taurine supplementation only increased plasma taurine concentrations in CONT group. Maternal plasma adiponectin concentrations increased in CAF and CAFT fed dams compared to CON and CONT fed dams and there was no effect of taurine. Hyperleptinemia was observed in CAF fed dams but not in CAFT fed dams. Malondialdehyde was significantly increased only in CAF fed dams. Litter size, sex ratio and birth weight were similar between the groups. There was an increase in neonatal mortality in CONT group. DISCUSSION This study showed that maternal taurine supplementation exerted modest protective effects on cafeteria diet induced maternal obesity. The increased neonatal mortality in CONT neonates indicates possible detrimental effects of taurine supplementation in the setting of normal pregnancy. Therefore, future studies should investigate the optimal dose of taurine supplementation and long term potential effects on the offspring.

Abstract
Background and Objectives: The intergenerational impacts of parental exposure to violence during childhood and adulthood have largely been investigated separately. This limits our understanding of how cumulative violence exposure over a lifespan elevates the risk of subsequent generation's maladjustment. To address this, we examined if parental exposure to violence during childhood and during adulthood was associated with increased emotional-behavioural and school difficulties among the children of these parents. Further, we examined if parental exposure to cumulative violence increased the odds of their children experiencing difficulties. Participants and Setting: 705 participants (354 mothers and 351 fathers) from the 2019 New Zealand Family Violence Survey, a population-based study conducted in New Zealand between March 2017 and March 2019. Methods: Multivariable logistic regressions were conducted to ascertain the impact of parental exposure to violence on children's outcomes after adjustment for sociodemographic characteristics. The impact of parental cumulative violence exposure on children's outcomes was also explored. Results: Findings indicated that children of parents who had histories of exposure to violence during childhood were at increased risk for experiencing emotional-behavioural or school difficulties. However, where parents reported a history of childhood abuse but not adult experience of violence, their children had similar odds of experiencing difficulties as the children of parents who had not been exposed to any violence in their lifetime. Children of parents who had been exposed to violence only during adulthood were at higher risk of experiencing emotional-behavioural difficulties compared with children of parents with no violence exposure. Children of parents with histories of exposure to violence during both childhood and adulthood had the highest prevalence of experiencing emotional/behavioural and school difficulties. Conclusion: These findings highlight the intergenerational impacts of violence exposure and the complex intersections between parents' and children's life experiences. Our findings suggest the need for violence prevention initiatives to foster the development of safe, stable and nurturing relationships and to expand services for parents already exposed to violence to build resilience and to break the inter-generational cycle of disadvantage.

Abstract
As postpartum obesity is becoming a global public health challenge, there is a need to apply postpartum obesity modeling to determine the indicators of postpartum obesity using an appropriate statistical technique. This research comprised two phases, namely: (i) development of a previously created postpartum obesity modeling; (ii) construction of a statistical comparison model and introduction of a better estimator for the research framework. The research model displayed the associations and interactions between the variables that were analyzed using the Structural Equation Modeling (SEM) method to determine the body mass index (BMI) levels related to postpartum obesity. The most significant correlations obtained were between BMI and other substantial variables in the SEM analysis. The research framework included two categories of data related to postpartum women: living in urban and rural areas in Iran. The SEM output with the Bayesian estimator was 81.1%, with variations in the postpartum women's BMI, which is related to their demographics, lifestyle, food intake, and mental health. Meanwhile, the variation based on SEM with partial least squares estimator was equal to 70.2%, and SEM with a maximum likelihood estimator was equal to 76.8%. On the other hand, the output of the root mean square error (RMSE), mean absolute error (MSE) and mean absolute percentage error (MPE) for the Bayesian estimator is lower than the maximum likelihood and partial least square estimators. Thus, the predicted values of the SEM with Bayesian estimator are closer to the observed value compared to maximum likelihood and partial least square. In conclusion, the higher values of R-square and lower values of MPE, RMSE, and MSE will produce better goodness of fit for SEM with Bayesian estimators.

Abstract
Background We have previously reported that female mice exposed to maternal separation and early weaning (MSEW), a model of early life stress, show exacerbated diet-induced obesity associated with hypertension. The goal of this study was to test whether MSEW promotes angiotensin II-dependent hypertension via activation of the renin-angiotensin system in adipose tissue. Methods and Results MSEW was achieved by daily separations from the dam and weaning at postnatal day 17, while normally reared controls were weaned at postnatal day 21. Female controls and MSEW weanlings were placed on a low-fat diet (LF, 10% kcal from fat) or high-fat diet (HF, 60% kcal from fat) for 20 weeks. MSEW did not change mean arterial pressure in LF-fed mice but increased it in HF-fed mice compared with controls (P<0.05). In MSEW mice fed a HF, angiotensin II concentration in plasma and adipose tissue was elevated compared with controls (P<0.05). In addition, angiotensinogen concentration was increased solely in adipose tissue from MSEW mice (P<0.05), while angiotensin-converting enzyme protein expression and activity were similar between groups. Chronic enalapril treatment (2.5 mg/kg per day, drinking water, 7 days) reduced mean arterial pressure in both groups of mice fed a HF (P<0.05) and abolished the differences due to MSEW. Acute angiotensin II-induced increases in mean arterial pressure (10 μg/kg SC) were attenuated in untreated MSEW HF-fed mice compared to controls (P<0.05); however, this response was similar between groups in enalapril-treated mice. Conclusions The upregulation of angiotensinogen and angiotensin II in adipose tissue could be an important mechanism by which female MSEW mice fed a HF develop hypertension.

Abstract
Background: Becoming a parent is viewed as one of the most important transitions in one's life. However, a history of childhood maltreatment may affect the adjustment to parenthood. Objective: The objective of this review was to synthesize the current evidence base to further our understanding of prospective and new parents' experiences in the transition to parenthood (pregnancy to 2 years post-birth), in the context of having a childhood maltreatment history. Method: A scoping review of the literature was conducted using the following online databases: PubMed, PsycINFO, PsycNET, and Published International Literature of Traumatic Stress. Results: The findings were synthesized into a four-component theoretical framework, which included mental health of the parent, physical changes, parental view of the child, and view of the self as a parent. A total of 69 papers, including 181,537 participants (of whom 30,482 mothers and 235 fathers had maltreatment histories), investigated the transition to parenthood. The majority of the studies showed that parents with a maltreatment history may suffer from a range of mental health problems during the transition to parenthood, experience more negative physical changes, and have more negative views of their child (or children). However, they reported both positive and negative experiences regarding their identity as a parent. Conclusions: The findings suggest that maltreatment is a risk factor for a more challenging transition to parenthood. Experiences of fathers with maltreatment histories merit more attention, as do those of parents in low- and middle-income countries. Future directions should include predictors of positive experiences and the development of early interventions to improve outcomes for this population.
