- PURPOSE: With the population-based, prospective Biology, Affect, Stress, Imaging and Cognition (BASIC) cohort, we aim to investigate the biopsychosocial aetiological processes involved in perinatal depression (PND) and to pinpoint its predictors in order to improve early detection.PARTICIPANTS: From September 2009 to November 2018, the BASIC study at Uppsala University Hospital, Sweden, has enrolled 5492 women, in 6478 pregnancies, of which 46.3% first-time pregnancies and with an average age of 31.5 years. After inclusion around gestational week 16-18, participants are followed-up with data collection points around gestational week 32, at childbirth, as well as three times postpartum: after 6 weeks, 6 months and 1 year. At the last follow-up, 70.8% still remain in the cohort.FINDINGS TO DATE: In addition to internet-based surveys with self-report instruments, participants contribute with biological samples, for example, blood samples (maternal and from umbilical cord), biopsies (umbilical cord and placenta) and microbiota samples. A nested case-control subsample also takes part in cognitive and emotional tests, heart rate variability tests and bioimpedance tests. Subprojects have identified various correlates of PND of psychological and obstetric origin in addition to factors of the hypothalamic-pituitary-adrenal axis and immune system.FUTURE PLANS: In parallel with the completion of data collection (final follow-up November 2019), BASIC study data are currently analysed in multiple subprojects. Since 2012, we are conducting an ongoing follow-up study on the participants and their children up to 6 years of age (U-BIRTH). Researchers interested in collaboration may contact Professor Alkistis Skalkidou (corresponding author) with their request to be considered by the BASIC study steering committee.

- Objective: To study whether conception by means of in vitro fertilization (IVF) is associated with maternal depressive symptoms during pregnancy or postpartum.Design: Longitudinal observational study. Setting: University hospital.Patient(s): A total of 3,283 women with singleton pregnancies receiving antenatal care and delivering in Uppsala from 2010 to 2015.Intervention(s): A web-based self-administered structured questionnaire including sociodemographic, clinical and pregnancy-related items, and the Edinburgh Postnatal Depression Scale (EPDS) was delivered at 17 and 32 gestational weeks and at 6 weeks and 6 months postpartum.Main Outcome Measure(s): Prevalence of significant depressive symptoms (EPDS >= 12) and EPDS scores.Result(s): A total of 167 women (5%) had conceived via IVF and 3,116 (95%) had a spontaneous pregnancy. IVF mothers were more frequently >= 35 years of age (46.1% vs. 22.6%) and primiparous (71.7% vs. 49.9%) and had a higher cesarean delivery rate (22.4% vs. 14.2%). Demographic and clinical characteristics were otherwise similar between the two groups. Significant depressive symptoms were reported by 12.8%, 12.4%, 13.8%, and 11.9% of women at 17 and 32 gestational weeks and 6 weeks and 6 months postpartum, respectively. The prevalence of depressive symptoms and the EPDS scores during pregnancy and postpartum were similar between women conceiving spontaneously or through IVF. The mode of conception was not associated with significant depressive symptoms at any time point, even when adjusting for several possible confounders in multivariable logistic regression analysis.Conclusion(s): Despite the psychologic distress characterizing subfertility and its treatment, conception by means of IVF is not associated with maternal depressive symptoms during pregnancy or postpartum.

Seasonal aspects of peripartum depressive symptoms
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Every year, a large proportion of pregnant and newly delivered women develop peripartum depression, a condition that may cause long-term suffering for the entire family. Although there is a lack of consensus, some studies propose an association between season and the risk of developing depression during pregnancy and the postpartum period. Furthermore, the immune system, which undergoes numerous structural changes during pregnancy, has been suggested to exhibit seasonal variations. In addition, discrepancies in metabolic profiles have been reported between women with and without depression after childbirth. This thesis aimed to investigate seasonal aspects of peripartum depressive symptoms (PPDS) and biological markers during the peripartum period. The data mainly derived from the prospective population-based Biology, Affect, Stress, Imaging, and Cognition (BASIC) study, but data were also included from the longitudinal population-based Uppsala-Athens (UPPSAT) study. The presence of depressive symptoms was primarily assessed using the Edinburgh Postnatal Depression Scale (EPDS). There were no consistent associations between season, meteorological parameters, air pollen count, and PPDS. Moreover, a number of inflammatory markers were identified as having seasonal variations among samples from pregnant women. On the contrary, only one marker had a seasonal pattern during the early postpartum period. Furthermore, metabolic profiles were not discriminatory between pregnant women with and without depressive symptoms. However, when divided into summer and winter childbirths, discrepancies were identified in metabolic profiles between summer cases and controls, as well as between summer and winter controls. In summary, the studies included in this thesis suggest that season, specifically, is not associated with PPDS. However, season may have a moderating effect on the association between depressive symptoms and the metabolic profile of pregnant women. In addition, the seasonal variations appears more prominent among inflammatory markers during late pregnancy, compared with the early postpartum period. These findings suggest that women need equal attention in clinical care regardless of the season during which they give birth. Future studies on biological aspects of PPDS and immune-associated conditions are encouraged to also assess seasonality.

- Seasonal variations have recently been described in biomarkers, cell types, and gene expression associated with the immune system, but so far no studies have been conducted among women in the peripartum period. It is of note that pregnancy complications and outcomes, as well as autoimmune diseases, have also been reported to exhibit seasonal fluctuations. We report here a clear-cut seasonal pattern of 23 inflammatory markers, analysed using proximity-extension assay technology, in pregnant women. The inflammatory markers generally peaked in the spring and had a trough in the autumn. During the postpartum period we found seasonality in one inflammatory marker, namely monocyte chemotactic protein 4 (MCP-4). Our findings suggest that seasonal variations in peripheral inflammatory markers are only observed during pregnancy. The results of this study could be valuable to professionals working within the field of immunology-related areas, and provide insight for the understanding of obstetric complications.

- Postpartum depression (PPD) is a common childbirth complication, affecting 10-15 % of newly delivered mothers. This study aims to assess the association between personality factors and PPD. All pregnant women during the period September 2009 to September 2010, undergoing a routine ultrasound at Uppsala University Hospital, were invited to participate in the BASIC study, a prospective study designed to investigate maternal well-being. Depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) while the Depression Self-Rating Scale (DSRS) was used as a diagnostic tool for major depression. Personality traits were evaluated using the Swedish Universities Scale of Personality (SSP). One thousand thirty-seven non-depressed pregnant women were included in the study. Non-depressed women reporting high levels of neuroticism in late pregnancy were at high risk of developing postpartum depressive symptoms (PPDSs) at 6 weeks and 6 months after delivery, even after adjustment for confounders (adjusted odds ratio (aOR) = 3.4, 95 % confidence interval (CI) 1.8-6.5 and adjusted odds ratio (aOR) = 3.9, 95 % CI 1.9-7.9). The same was true for a DSRS-based diagnosis of major depression at 6 months postpartum. Somatic trait anxiety and psychic trait anxiety were associated with increased risk for PPDS at 6 weeks (aOR = 2.1, 95 % CI 1.2-3.5 and aOR = 1.9, 95 % CI 1.1-3.1), while high scores of mistrust were associated with a twofold increased risk for PPDS at 6 months postpartum (aOR 1.9, 95 % CI 1.1-3.4). Non-depressed pregnant women with high neuroticism scores have an almost fourfold increased risk to develop depressive symptoms postpartum, and the association remains robust even after controlling for most known confounders. Clinically, this could be of importance for health care professionals working with pregnant and newly delivered women.

Personality and the HPA-axis in Association with Postpartum Depression
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Postpartum depression is a psychiatric disorder affecting a substantial proportion of newly delivered women, and remains a significant cause of childbirth-related morbidity. The aim of the present thesis was to examine psychological, endocrine and genetic aspects of postpartum depression in a large, population-based sample of women in Uppsala, Sweden. All included studies were undertaken as parts of the BASIC-project, a longitudinal study on psychological wellbeing during pregnancy and the postpartum period. Study participants were screened for depressive symptoms in pregnancy week 17 and 32 as well as at six weeks and six months postpartum, mainly by use of the Swedish version of the Edinburgh Postnatal Depression Scale (EPDS). Furthermore, personality was assessed with the Swedish universities Scale of Personality (SSP) in pregnancy week 32. Evening cortisol levels in saliva were measured in pregnancy week 36 and at six weeks postpartum. Blood samples were obtained to measure corticotropin-releasing hormone levels (CRH) and to perform genetic analyses. The results of this thesis demonstrate that neuroticism is a strong and independent predictive factor of depressive symptoms at six weeks and six months postpartum, and has a significant mediatory role in the association between a single nucleotide polymorphism in the hydroxysteroid (11-beta) dehydrogenase 1 gene (HSD11B1) and postpartum depression. Furthermore, women with postpartum depressive symptoms present with a dysregulated hypothalamic-pituitary-adrenal axis activity in terms of elevated cortisol levels postpartum, as well as elevated CRH levels in mid-gestation. In conclusion, this thesis develops current knowledge on several attributes of postpartum depression. Further studies are required to replicate and expand on these results, which would further contribute to early identification of women at risk of postpartum depression and adoption of proper interventions that may moderate the short- and long-term consequences of the disorder.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Postpartum depression predisposes to maternal affective and somatic disorders. It is important to identify which women are at an increased risk of subsequent morbidity and would benefit from an intensified follow-up. Self-harm thoughts (SHTs), with or without other depressive symptomatology, might have prognostic value for maternal health beyond the postpartum period.Aim: This study is to investigate the somatic and psychiatric morbidity of postpartum women with SHTs, with or without other depressive symptoms, over a 7-year follow-up period.Materials and methods: The subjects for this study are derived from a population based Swedish cohort of women who gave birth at Uppsala University Hospital (May 2006-June 2007) and who answered the Edinburgh Postnatal Depression Scale (EPDS) at 5 days, 6 weeks, and 6 months postpartum. Three groups were included: women reporting SHTs (SHT group, n = 107) on item 10 of the EPDS; women reporting depressive symptoms, i.e., EPDS >= 12 at 6 weeks and/or 6 months postpartum, without SHTs (DEP group, n = 94); and randomly selected controls screening negatively for postpartum depression (CTL group, n = 104). The number of diagnostic codes for somatic and psychiatric morbidity according to the International Statistical Classification of Diseases and Related Health Problems system, and the number of medical interventions were retrieved from medical records over 7 years following childbirth and were used as the outcome measures, together with any prescription of antidepressants and sick leave during the follow-up.Results: The SHT group had the highest psychiatric morbidity of all groups and more somatic morbidity than controls. Affective disorders were more common in the SHT and the DEP groups compared with controls, as well as antidepressant prescriptions and sick leave. One-fifth of women with SHTs did not screen positive for depressive symptoms; nevertheless, they had more somatic and psychiatric morbidity than the control group.Conclusion: Women reporting thoughts of self-harm in the postpartum period are at an increased risk of somatic and psychiatric morbidity during a follow-up of 7 years after delivery, and this increased risk may not be fully attributed to depressive symptoms. Results underline the importance of screening for self-harm symptoms postpartum and point to a need for individualized follow-up.

- The aim of this population-based, longitudinal study was to assess the association between nausea and vomiting in pregnancy (NVP) and perinatal depressive symptoms. Pregnant women (N = 4239) undergoing routine ultrasound at gestational week (GW) 17 self-reported on NVP and were divided into those without nausea (G0), early (<= 17 GW) nausea without medication (G1), early nausea with medication (G2), and prolonged (>17 GW) nausea (G3). The Edinburgh Postnatal Depression Scale at GW 17 and 32 (cut-off >= 13) and at six weeks postpartum (cut-off >= 12) was used to assess depressive symptoms. Main outcome measures were depressive symptoms at GW 32 and at six weeks postpartum. NVP was experienced by 80.7%. The unadjusted logistic regression showed a positive association between all three nausea groups and depressive symptoms at all time-points. After adjustment, significant associations with postpartum depressive symptoms remained for G3, compared to G0 (aOR = 1.66; 95% CI 1.1-2.52). After excluding women with history of depression, only the G3 group was at higher odds for postpartum depressive symptoms (aOR = 2.26; 95% CI 1.04-4.92). In conclusion, women with prolonged nausea have increased risk of depressive symptoms at six weeks postpartum, regardless of history of depression.

- Individual differences in the response of the stress system to hormonal changes during pregnancy and the postpartum period render some women susceptible to developing depression. The present study sought to investigate peripartum depression and stress hormones in relation to stress-related genotypes. The Edinburgh Postnatal Depression Scale was used to assess peripartum depressive symptoms in a sample of 1629 women, followed from pregnancy week seventeen to six months postpartum. Genotypes of ninety-four haplotype-tag single nucleotide polymorphisms (SNPs) in sixteen genes of the hypothalamus-pituitary-adrenal axis pathway were analyzed and data on psychosocial and demographic factors was collected. In sub-studies, salivary cortisol awakening response in gestational week 35–39, salivary evening cortisol levels in gestational week 36 and postpartum week 6, and blood cortisol and cortisone levels in gestational week 35–39 were analyzed. SNP-set kernel association tests were performed at the gene-level, considering psychosocial and demographic factors, followed by post-hoc analyses of SNPs of significant genes. Statistically significant findings at the 0.05 p-level included SNPs in the hydroxysteroid 11-beta dehydrogenase 1 (HSD11B1) gene in relation to self-rated depression scores in postpartum week six among all participants, and serpin family A member 6 (SERPINA6) gene at the same time-point among women with de novo onset of postpartum depression. SNPs in these genes also associated with stress hormone levels during pregnancy. The present study adds knowledge to the neurobiological basis of peripartum depression by systematically assessing SNPs in stress-regulatory genes and stress-hormone levels in a population-based sample of women. © 2019 Elsevier Ltd
