RESUMEN
BACKGROUND: Research exploring the relationship between prenatal infection and child behavioural outcomes would benefit from further studies utilising full-population samples with the scale to investigate specific infections and to employ robust designs. We tested the association among several common infections requiring inpatient admission during and after pregnancy with a range of childhood behavioural outcomes, to determine whether any negative impact was specific to the period of foetal development. METHODS: The sample included all mother-offspring pairs from the Australian state of New South Wales (NSW) for whom the child commenced their first year of full-time schooling in 2009 (~age 5 years; n = 77,302 offspring), with records linked across four health administrative data sets including the NSW perinatal data collection (PDC), the NSW admitted patient data collection (APDC) and the NSW component of the 2009 Australian Early Development Census (AEDC). Multivariable linear regression was used to test associations between a number of infections requiring inpatient admission during and after pregnancy with a range of teacher assessed behavioural outcomes. RESULTS: Associations specific to the prenatal period were only found for streptococcus A although this would need to be reproduced in external samples given the low prevalence. Otherwise, 12 out of 15 selected infections either showed no association prenatally or also demonstrated associations in the 12 months after pregnancy. For example, prenatal hepatitis C, influenza and urinary E. coli infections were associated with lower scores of several domains of childhood behaviour, but even stronger associations were found when these same maternal infections occurred after pregnancy. CONCLUSIONS: The prenatal infections we tested appeared not to impact childhood behaviour by altering foetal neurodevelopment. Rather, the strong associations we found among infections occurring during and after pregnancy point to either residual socioeconomic/lifestyle factors or a shared familial/genetic liability between infections and behavioural problems.

A cross-sectoral partnership was formed in 2021 in support of the recommendations in an audit on access to state-funded mental health services. In this first paper, we aimed to describe the demographic and service utilisation of adults with a mental health diagnosis in the Western Australian state-funded health system from 2005 to 2021. Inpatient, emergency department, specialised (ambulatory) community mental health service, and death records were linked in individuals aged ≥ 18 years with a mental health diagnosis in Western Australia. Altogether, 392,238 individuals with at least one mental health service contact between 1st January 2005 and 31st December 2021 were included for analysis. Females, Aboriginal and/or Torres Strait Islander people, and those who lived outside major cities or in the most disadvantaged areas were more likely to access state-funded mental health services. While the number of individuals who accessed community mental health services increased over time (from 28,769 in 2005 to 50,690 in 2021), the percentage increase relative to 2005 was notably greater for emergency department attendances (127% for emergency department; 76% for community; and 63% for inpatient). Conditions that contributed to the increase for emergency department were mainly alcohol disorder, reaction to severe stress and adjustment disorders, and anxiety disorders. Sex differences were observed between conditions. The pattern of access increased for emergency department and the community plus emergency department combination. This study confirmed that the patterns of access of state-funded mental health services have changed markedly over time and the potential drivers underlying these changes warrant further investigation.
RESUMEN
BACKGROUND & AIM: Fast-track or enhanced recovery after surgery (ERAS) is a care pathway for surgical patients based on a multidisciplinary team approach aimed at optimising recovery without increasing risk with protocols based on scientific evidence, which is monitored continuously to ensure compliance and improvement. These protocols have been shown to reduce the duration of postoperative mechanical ventilation and intensive care unit (ICU) length of stay (LOS) following paediatric cardiac surgery. We present the first structured implementation of ERAS in paediatric cardiac surgery in Australia. METHODS: All patients enrolled in the ERAS pathway between October 2019 and July 2023 were identified. Demographic and perioperative data were collected retrospectively from hospital records for patients operated before June 2021 and prospectively from June 2021. A control group (non-ERAS) was identified using propensity matching from patients who underwent similar procedures and were not enrolled in the ERAS pathway (prior to October 2019). Patients were matched for age, weight, and comprehensive Aristotle score. Outcomes of interest were duration of postoperative mechanical ventilation, ICU LOS, readmission to the ICU, hospital LOS, cardiac reintervention rate, postoperative complication rate, and number of 30-day readmissions. RESULTS: Of 1,084 patients who underwent cardiac surgery during the study period (October 2019-July 2023), 121 patients (11.2%) followed the ERAS pathway. The median age at the time of surgery was 4.8 years (interquartile range [IQR] 2.8-8.8 years). The most common procedure was the closure of atrial septal defect (n=58, 47.9%). The median cardiopulmonary bypass and cross-clamp times were 40 min (IQR 28-53.5 minutes) and 24.5 min (IQR 13-34 minutes) respectively. The majority were extubated in the operating theatre (n=108, 89.3%). The median ICU and hospital LOS were 4.5 hrs (IQR 4.1-5.6 hours) and 4 days (IQR 4-5 days) respectively. None of the patients required readmission to the ICU within 24 hrs of discharge from the ICU. Three (3) patients (2.5%) required reintervention. When compared with the non-ERAS group, the duration of postoperative mechanical ventilation, ICU and hospital LOS were significantly lower in the ERAS group. There was no significant difference in the ICU readmission rate, reintervention rate, complication rate, and number of 30-day readmissions between both groups. CONCLUSIONS: ERAS after paediatric cardiac surgery is feasible and safe in select patients with low preoperative risk. This pathway reduces the duration of postoperative mechanical ventilation, ICU and hospital LOS without increasing risks, enabling the optimisation of resources.

BACKGROUND: Privacy, access and security concerns can hinder the availability of health data for research. The use of synthesised data in place of de-identified electronic health records (EHRs) presents an opportunity to conduct research while minimising privacy concerns. OBJECTIVES: To examine whether synthesised data can replicate two prenatal epidemiological associations: between prenatal smoking and lower birthweight, and between prenatal mood disorders and lower birthweight, using data synthesised from de-identified health administrative data collections. METHODS: We generated two synthetic datasets, using parametric and non-parametric data generating methods, and examined the synthetic data for evidence of privacy concerns. Next, univariable and multivariable logistic regression was utilised to estimate the associations in both synthetic datasets, with results then compared to the real data. RESULTS: Both synthesised datasets performed well in identifying the reduction in birthweight associated with prenatal smoking, while the non-parametric data underestimated the reduction in birthweight associated with prenatal mood disorders. Improbable relationships between some variables were identified in the parametric synthesised data, however, these can be addressed with simple rules during data synthesis. No duplicate rows (i.e., exact copies of de-identified data) were found in the parametric data, while only 0.6% of the rows in the non-parametric data were duplicated. CONCLUSIONS: Both synthesised datasets performed well in replicating the statistical properties of the original data while addressing privacy issues. Data synthesis methods provide an opportunity for researchers to utilise health data while managing privacy and security concerns.

BACKGROUND: Perinatal depression is often underdiagnosed; consequently, many women suffer perinatal depression without follow-up care. Screening for depressive symptoms during the perinatal period has been recommended in Australia to increase detection and follow-up of women suffering from depressive symptoms. Screening rates have gradually increased over the last decades in Australia. OBJECTIVE: To explore trends in referrals of women to community mental health services during the perinatal period, and prenatal and postnatal admissions to psychiatric units, among those who gave birth in Queensland between 2009 and 2015. METHOD: Retrospective analyses of data from three linked state-wide administrative data collections. Trend analyses using adjusted Poisson regression models examined 426,242 births. Outcome variables included referrals to specialised mental health services; women admitted with a mood disorder during the second half of their pregnancy and during the first 3 months of the postnatal period; and women admitted with non-affective psychosis disorders during the second half of their pregnancy and during the first 3 months of the postnatal period. RESULTS: We found an increase in mental health referrals during the perinatal period over time (adjusted incidence rate ratio, 1.07; 95% confidence interval, [1.06, 1.08]) and a decrease in admissions with mood disorders during the first 3 months of the postnatal period (adjusted incidence rate ratio, 0.95; 95% confidence interval, [0.94, 0.98]). We did not find any changes in rates of admission for other outcomes. CONCLUSION: Since the introduction of universal screening in Queensland, referrals for mental health care during the perinatal period have increased, while admissions for mood disorders in the first 3 months after delivery decreased.

AIM: In 2020, the European Kidney Function Consortium (EKFC) published a new creatinine-based equation to estimate glomerular filtration rate (eGFR) to overcome known limitations in existing equations. The aim of this study is to model the potential impact on service referral and health expenditure of routine reporting of eGFR using the EKFC equation as compared to the CKD-EPI equation in a Western Australian population. METHODS: eGFR was calculated for 760 614 patients with 2 368 234 creatinine results using the CKD-EPI and EKFC formulas. Patients were grouped into a CKD cohort if they had at least two eGFR results of <60 ml/min/1.73 m2 from tests at least 90 days apart. The impact of each equation on the reclassification of CKD stages, CKD cohort classification, the rate of change in eGFR and direct health costs were assessed. RESULTS: About 90.66% of patients had a lower eGFR when calculated using the EKFC equation. About 12.6% of individuals were classified into a different CKD stage using the EKFC equation with 97.43% of these patients classified into a higher (more advanced) stage. There was a 25.9% increase in the number of patients identified as having CKD when calculated using the EKFC equation. Direct health costs also increased with the use of EKFC reporting. CONCLUSION: Use of the EKFC equation will increase population prevalence of CKD and will result in a shift to higher stages of CKD. This has implications for monitoring and referral of patients within specialist services and has the potential to increase the need for multidisciplinary care.

OBJECTIVES: There is limited evidence on the impact of parental mental health problems on offspring's educational outcomes. We investigated the impact of maternal anxiety and depressive symptoms, as well as paternal emotional problems on the educational outcomes of their adolescent and young adult offspring. METHODS: We used data from a longitudinal birth cohort recruited between 1989 and 1991 in Australia (the Raine Study). The Depression, Anxiety and Stress Scale was used to assess maternal depressive and anxiety symptoms, and a self-reported question was used to measure paternal mental health problems. Both were assessed when the offspring was aged 10 years. Outcomes included offspring's self-reported education attainment-not completing year 10 at age 17, not attending tertiary education at ages 17 and 22 and primary caregiver's reports of offspring's academic performance at age 17. RESULTS: A total of 1033, 1307 and 1364 parent-offspring pairs were included in the final analysis exploring the association between parental mental health problems and offspring's academic performance at school, completing year 10 and attending tertiary education, respectively. After adjusting for potential confounders, the offspring of mothers with anxiety symptoms were 3.42 times more likely than the offspring of mothers without anxiety symptoms to have poor or below-average academic performance (odds ratio = 3.42; 95% confidence interval = [1.31, 8.92]) and more than 2 times more likely to not attend tertiary education (odds ratio = 2.55; 95% confidence interval = [1.10, 5.5.88]) and not to have completed year 10 (odds ratio = 2.13; 95% confidence interval = [1.04, 4.33]). We found no significant associations between maternal depressive symptoms or paternal emotional problems and offspring educational attainment. CONCLUSION: Maternal anxiety symptoms, but not depression and paternal emotional problems, are associated with poor educational attainment and achievement in adolescent offspring. The findings highlight that efforts to improve the outcomes of offspring of mothers with anxiety could focus on educational attainment.

BACKGROUND: Evidence shows that depressive symptoms during pregnancy increase the risk of an intervention during delivery (induction, the use of forceps or vacuum, and caesarean sections (CS)). Many women with depression during pregnancy are not identified and therefore will not receive appropriate follow up of their symptoms. We hypothesised that routine screening for depressive symptoms during pregnancy could reduce detrimental consequences of depressive symptoms on delivery outcomes. AIM: We explored the association between screening for depressive symptoms during pregnancy and delivery outcomes. MATERIALS AND METHODS: A cross-sectional analysis of state-wide administrative data sets. The population included all women who delivered a singleton in Queensland between the July and December of 2015. Logistic regression analyses were run in 27 501 women (93.1% of the total population) with information in all variables. The following were the main outcomes: onset of labour, CS, instrumental vaginal delivery, and all operative deliveries (including both CS and instrumental vaginal deliveries). RESULTS: Women who completed the screening had increased odds of a spontaneous onset of labour (adjusted odds ratio (aOR) 1.18; 95% CI 1.09-1.27) and decreased odds of an operative delivery (instrumental or CS) (aOR 0.88; 95% CI 0.81-0.96). Among women who had a vaginal delivery, those who completed the screening had decreased odds of having an instrumental delivery (aOR 0.84; 95% CI 0.74-0.97). Sensitivity analyses in women who did not have a formal diagnosis of depression showed similar results. CONCLUSION: Our findings suggest that screening may decrease interventions during delivery in women with depressive symptoms.

BACKGROUND: Existing methods of measuring birth size asymmetry based on ratios of growth parameters are clinically useful but simplistic, and as such may have limited usefulness in studies of aetiology. OBJECTIVES: We aimed to develop a novel method of measuring asymmetric fetal growth at birth and demonstrate its utility in characterising the perturbed growth associated with a number of prenatal exposures and neonatal outcomes. METHODS: Data were drawn from the Queensland (QLD) Perinatal Data Collection, which included all livebirths in the Australian state of QLD between July 2010 and December 2015, with analyses restricted to babies born between 32 and 42 weeks of gestation (n = 280 084). Novel measures of asymmetric birthweight, length, and head circumference were developed using a weighted average, representing "how far" an individual's given birth size measure deviated from the sample average and their other birth size measures. Associations among prenatal exposures and neonatal outcomes with the new asymmetry measures and traditional ratio measures (ie ponderal index, brain-to-body weight ratio, and birth length divided by head circumference) were then compared using log-binomial and multinomial regressions. RESULTS: The new asymmetry measures clearly indicated that prenatal smoking was linked to a disproportionate decrease in all birth size measures and that low birthweight asymmetry and low birth head circumference asymmetry were specifically associated with neonatal respiratory distress and chromosomal abnormalities, respectively. When these same associations were tested using the traditional ratios, the estimates were weak, imprecise, and non-specific. CONCLUSIONS: We developed a new approach to measuring fetal growth asymmetry which provides complimentary insights against the existing ratios approach. Associations with the new asymmetry measures were more precise and easier to interpret than the associations obtained using the ratios, and may better reflect the underlying pathological processes, providing an advantage when investigating the aetiologies of perturbed fetal growth.

OBJECTIVES: A major challenge for hospitals and clinicians is the early identification of neonates at risk of developing adverse conditions. We develop a model based on routinely collected administrative data, which accurately predicts two common disorders among early term and preterm (<39 weeks) neonates prior to discharge. STUDY DESIGN: The data included all inpatient live births born prior to 39 weeks (n = 154,755) occurring in the Australian state of Queensland between January 2009 and December 2015. Predictor variables included all maternal data captured in administrative records from the beginning of gestation up to, and including, the delivery, as well as neonatal data recorded at the delivery. Gradient boosted trees were used to predict neonatal respiratory distress syndrome and hypoglycaemia prior to discharge, with model performance benchmarked against a logistic regression models. RESULTS: The gradient boosted trees model achieved very high discrimination for respiratory distress syndrome [AUC = 0.923, 95% CI (0.917, 0.928)] and good discrimination for hypoglycaemia [AUC = 0.832, 95% CI (0.827, 0.837)] in the validation data, as well as outperforming the logistic regression models. CONCLUSION: Our study suggests that routinely collected health data have the potential to play an important role in assisting clinicians to identify neonates at risk of developing selected disorders shortly after birth. Despite achieving high levels of discrimination, many issues remain before such models can be implemented in practice, which we discuss in relation to our findings.

AIMS: Understanding contexts in which social harms from drinking occur can help develop context-based harm reduction efforts. However, there is little knowledge of specific drinking contexts where such harms occur and whether these are gender or age specific. We aimed to investigate associations of a range of drinking contexts and social harms from drinking among young adults at age 30. METHODS: We used data from 2187 30-year-old adults. Latent constructs of gender-specific drinking contexts were created using factor analysis. We performed multivariate logistic regression between drinking contexts and a range of social harms from drinking, separately by gender. RESULTS: After accounting for social roles and binge drinking, gender-specific solitary drinking contexts ('home drinking' for men and 'daytime drinking' for women) were positively associated with marital problems and problems with other family members and friends. Conversely, 'social drinking' was not. Work-related drinking among men was associated with marital/intimate relationship problems and friendship problems. After accounting for mental health symptoms, women's home drinking was associated with marital problems. CONCLUSION: We found that experiences of social harms from drinking at 30 years differ depending on the drinker's gender and context. Our findings suggest that risky contexts and associated harms are still significant among 30-year-old adults, indicating that a range of gender-specific drinking contexts should be represented in harm reduction campaigns. The current findings also highlight the need to consider gender to inform context-based harm reduction measures and to widen the age target for these beyond emerging adults.

INTRODUCTION: This study aims to explore association between maternal depressive symptoms and infant feeding practice at hospital discharge. METHODS: Data were obtained from a birth cohort study based in Australia that linked to health administrative records. Maternal demographic data, mental health status derived from the Edinburgh Postnatal Depression Scale (EPDS), feeding practices of livebirths of at least 400 g or gestation periods of at least 20 weeks recorded during July-December 2015 were included (n = 14,658). Logistic regression models were performed to test association between presence of depressive symptoms and exclusive breast or formula feeding within 24 h prior to hospital discharge while adjusting for covariates known to be associated with breastfeeding. RESULTS: About 12% of women self-reported having depressive symptoms (EPDS score ≥ 10). Although only 7% of women (n = 1012) exclusively formula fed their babies, having depressive symptoms was associated with a 51% higher likelihood of exclusive formula feeding at hospital discharge. The association remains significant after adjustment for maternal age, gestational weeks, number of previous pregnancies, socioeconomic and partner status (p < 0.001) and all other covariates (p = 0.009). CONCLUSIONS FOR PRACTICE: Having depressive symptoms was associated with increased likelihood of exclusive formula feeding. Routine measurement post-delivery and early management of maternal depressive symptoms may influence infant feeding practice and reduce prevalence of exclusive formula feeding at hospital discharge.

OBJECTIVES: We assessed the impact of caesarean delivery on offspring respiratory and intestinal infection. METHODS: Data were extracted from all live births (n = 429,058) occurring in the Australian state of Queensland between January 2009 and December 2015, and followed for 12 months. Births were categorised as either non-medically indicated caesarean or vaginal delivery and each offspring had a record (present/absent) of respiratory and intestinal infection hospitalisation for each month from birth to 12 months. RESULTS: Infants delivered by non-medically indicated caesarean were more likely to experience respiratory infection [OR = 1.51 (1.15, 1.99)] and intestinal infection [OR = 1.74 (1.19, 2.55)] than those born by vaginal delivery. In the propensity score weighted analyses the estimate for respiratory infection was similar but non-significant [OR = 1.52 (0.99, 2.31)], while the association with intestinal infection strengthened [OR = 2.21 (1.25, 3.89)]. CONCLUSIONS FOR PRATICE: Our findings provide strong evidence for a specific and clinically meaningful link between non-medically indicated caesarean delivery and infant intestinal infection.

BACKGROUND: Balloon valvuloplasty and surgical aortic valvotomy have been the treatment mainstays for congenital aortic stenosis in children. Choice of intervention often differs depending upon centre bias with limited relevant, comparative literature. OBJECTIVES: This study aims to provide an unbiased, contemporary matched comparison of these balloon and surgical approaches. METHODS: Retrospective analysis of patients with congenital aortic valve stenosis who underwent balloon valvuloplasty (Queensland Children's Hospital, Brisbane) or surgical valvotomy (Royal Children's Hospital, Melbourne) between 2005 and 2016. Patients were excluded if pre-intervention assessment indicated ineligibility to either group. Propensity score matching was performed based on age, weight, and valve morphology. RESULTS: Sixty-five balloon patients and seventy-seven surgical patients were included. Overall, the groups were well matched with 18 neonates/25 infants in the balloon group and 17 neonates/28 infants in the surgical group. Median age at balloon was 92 days (range 2 days - 18.8 years) compared to 167 days (range 0 days - 18.1 years) for surgery (rank-sum p = 0.08). Mean follow-up was 5.3 years. There was one late balloon death and two early surgical deaths due to left ventricular failure. There was no significant difference in freedom from reintervention at latest follow-up (69% in the balloon group and 70% in the surgical group, p = 1.0). CONCLUSIONS: Contemporary analysis of balloon aortic valvuloplasty and surgical aortic valvotomy shows no difference in overall reintervention rates in the medium term. Balloon valvuloplasty performs well across all age groups, achieving delay or avoidance of surgical intervention.

Inconsistent results of the association between severe psychiatric disorders (SPD) in parents and the risk of disruptive behavioral disorders (DBD) including conduct disorders (CD) and oppositional defiant disorders (ODD) in the offspring have been found by previous epidemiologic studies. PubMed, EMBASE, PsycINFO, and Scopus were searched for relevant studies. Fourteen studies met the predefined criteria for inclusion. A meta-analysis of the included studies revealed an elevated risk of DBD in the offspring of parents with SPD, bipolar, and depressive disorders. Our further analysis considering the specific DBD as an outcome showed that parents with SPD are at an increased risk of having a child with ODD as well as CD. Moreover, the current meta-analysis found that the children of parents with bipolar disorder were also at increased risk of ODD and CD. Parental schizophrenia and depressive disorders were not associated with higher risks of ODD and CD in the offspring.

BACKGROUND: There are limited studies on the risk of depressive symptoms in adolescent offspring exposed to parental mental health problems in middle childhood. AIM: We investigated the association between parental mental health problems, particularly paternal emotional problems and maternal symptoms of anxiety and depression, and the risk of depressive symptoms in adolescent offspring aged 17. METHODS: The study included 995 parent-offspring pairs from the 1989-91 birth cohort (the Raine Study) in Western Australia. Log-binomial regression was used to assess the associations. RESULTS: An increased risk of depression symptoms was observed in the adolescent offspring of mothers with depressive [RR 1.45, 95% CI 1.13-1.86] as well as anxiety symptoms [RR 1.43, 95% CI 1.09-1.87].Compared to those non-exposed, offspring whose mothers reported comorbid anxiety and depressive symptoms were more likely to have developed depressive symptoms by late adolescence [RR 1.63, 95%CI 1.11-2.38]. An increased risk of depressive symptoms was also seen in the offspring of fathers with emotional problems [RR 1.29, 95%CI 1.01-1.53]. CONCLUSION: Our findings suggest an increased risk of depressive symptoms in the adolescent offspring of parents with mental health problems, specifically paternal emotional problems (29%) and maternal anxiety (43%), depression (45%), as well as comorbid anxiety and depressive symptoms (63%).

Hypertensive disorders of pregnancy (HDP) may increase the risk of offspring depression in childhood. Low birth weight is also associated with increased risk of mental health problems, including depression. This study sought to investigate (a) whether there is an association between HDP and the risk of depression in childhood and (b) whether low birth weight mediates this association. The current study is based on the Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective, population-based study that has followed a cohort of offspring since their mothers were pregnant (n = 6,739). Depression at the age of 7 years was diagnosed using parent reports via the Development and Well-Being Assessment (DAWBA). Log-binomial regression and mediation analyses were used. Children exposed to HDP were 2.3 times more likely to have a depression diagnosis compared with nonexposed children, adjusted Risk Ratio [RR], 2.31; 95% CI, [1.20, 4.47]. Low birth weight was a weak mediator of this association. Results were adjusted for confounding variables including antenatal depression and anxiety during pregnancy.This study suggests that fetal exposure to maternal hypertensive disorders of pregnancy increased the risk of childhood depression. The study adds to the evidence suggesting that the uterine environment is a critical determinant of neurodevelopmental and psychiatric outcomes.

Maternal thyroid dysfunction during pregnancy may contribute to offspring neurobehavioral disorders. In this paper, we investigate the relationship between maternal thyroid function during pregnancy and offspring depression and anxiety. Data were taken from the Avon Longitudinal Study of Parents and Children. A total of 2,920 mother-child pairs were included. Thyroid-stimulating hormone levels, free thyroxine (FT4), and thyroid peroxidase antibodies were assessed during the first trimester of pregnancy because maternal supply is the only source of thyroid hormone for the fetus during the first 12 weeks of gestation. Child symptoms of depression and anxiety were assessed using the Development and Well-Being Assessment at ages 7.5 and 15 years. The odds of presenting with depression and anxiety were estimated using the generalized estimating equation. The level of FT4 during the first trimester of pregnancy was associated with child depression combined at ages 7.5 and 15 (odds ratio = 1.21, 95% confidence interval [1.00, 1.14]. An increase of 1 standard deviation of FT4 during pregnancy increased the odds of child depression by 28% after adjustment made for potential confounders. No association was found among maternal levels of thyroid-stimulating hormone, FT4, and thyroid peroxidase antibodies and childhood anxiety. In conclusion, increased levels of FT4 during the first trimester of pregnancy appear be linked to greater risk of offspring depression.

PURPOSE: It is plausible that offspring born to mothers using tobacco during pregnancy may have increased risk of mood disorders (depression and bipolar disorders); however, mixed results have been reported. We conducted a systematic review and meta-analysis to investigate the magnitude and consistency of associations reported between prenatal tobacco use and mood disorders in offspring. METHODS: We systematically searched EMBASE, SCOPUS, PubMed and Psych-INFO for studies on mood disorders and prenatal tobacco use. Methodological quality of studies was assessed with the revised Newcastle-Ottawa Scale. We estimated pooled relative risk (RR) with inverse variance weighted random-effects meta-analysis. We performed leave-one-out analyses, and stratified analyses by a subgroup (depression and bipolar disorder). Potential publication bias was assessed by inspection of the funnel plot and Egger's test for regression asymmetry. This study protocol was prospectively registered in PROSPERO (CRD42017060037). RESULTS: Eight cohort and two case-control studies were included in the final meta-analysis. We found an increased pooled relative risk of mood disorders in offspring exposed to maternal prenatal tobacco use RRs 1.43 (95% CI 1.27-1.60) compared to no prenatal tobacco use. Similarly, the pooled relative risks of bipolar and depressive disorders in offspring were 1.44, (95% CI 1.15-1.80) and 1.44, (95% CI 1.21-1.71), respectively. Moreover, the pooled estimated risk of mood disorders was not significantly attenuated in the studies that reported sibling comparison results [RR = 1.21 (95% CI 1.04-1.41)]. CONCLUSION: Taken together, there was strong evidence for a small (RR < 2) association between prenatal tobacco use and mood disorders in offspring.

Maternal thyroid hormone may have impact on fetal brain development and consequently lead to offspring mental health problems. This study examined the role of maternal prenatal thyroid function on trajectories of offspring emotional and behavioural problems. Data were taken from the Avon Longitudinal Study of Parents and Children. A total of 4839 mother-child pairs were included. Thyroid-stimulating hormone (TSH) levels, free thyroxine (FT4), and thyroid peroxidase antibodies (TPO-Ab) were assessed during the first trimester of pregnancy. Childhood emotional and behavioural problems were assessed using the Strengths and difficulties questionnaire. A group-based modelling approach was used to identify the different trajectories of offspring emotional and behavioural problems reported by parents over four waves of measurement at age 3.5 (42 months), 6.75 (81 months), 9 and 11 years. Multinomial logistic regression was then used to test for an association between hormone levels and class membership. We identified four trajectories of offspring emotional and behavioural problems; normative-decreasing (49.7%), moderate-decreasing (35.7%), moderate-static (8.4%), and high-decreasing (6.2%) trajectory. There were no significant differences in the mean values of mother's FT4, TSH, and the proportion of mothers with positive TPO-Ab between trajectories. Univariable and multivariable multinomial logistic models showed no association between maternal thyroid function (FT4, TSH, and TPO-Ab) and the trajectories of offspring emotional and behavioural problems. The results of our study show that maternal thyroid parameters in a community population are not associated with trajectories of offspring emotional and behavioural problems.
