- Recent studies indicate that the immune system adaptation during pregnancy could play a significant role in the pathophysiology of perinatal depression. The aim of this study was to investigate if inflammation markers in a late pregnancy plasma sample can predict the presence of depressive symptoms at eight weeks postpartum. Blood samples from 291 pregnant women (median and IQR for days to delivery, 13 and 7-23days respectively) comprising 63 individuals with postpartum depressive symptoms, as assessed by the Edinburgh postnatal depression scale (EPDS≥12) and/or the Mini International Neuropsychiatric Interview (M.I.N.I.) and 228 controls were analyzed with an inflammation protein panel using multiplex proximity extension assay technology, comprising of 92 inflammation-associated markers. A summary inflammation variable was also calculated. Logistic regression, LASSO and Elastic net analyses were implemented. Forty markers were lower in late pregnancy among women with depressive symptoms postpartum. The difference remained statistically significant for STAM-BP (or otherwise AMSH), AXIN-1, ADA, ST1A1 and IL-10, after Bonferroni correction. The summary inflammation variable was ranked as the second best variable, following personal history of depression, in predicting depressive symptoms postpartum. The protein-level findings for STAM-BP and ST1A1 were validated in relation to methylation status of loci in the respective genes in a different population, using openly available data. This explorative approach revealed differences in late pregnancy levels of inflammation markers between women presenting with depressive symptoms postpartum and controls, previously not described in the literature. Despite the fact that the results do not support the use of a single inflammation marker in late pregnancy for assessing risk of postpartum depression, the use of STAM-BP or the novel notion of a summary inflammation variable developed in this work might be used in combination with other biological markers in the future.

Breastfeeding – Initiation, duration, attitudes and experiences
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to increase knowledge about factors that influence breastfeeding initiation and duration, as well as about women’s attitudes towards breastfeeding during pregnancy.The first two studies were a part of the UPPSAT project, a population-based cohort study conducted in Uppsala, Sweden. The women answered questionnaires five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration. Eight hundred and seventy-nine women and 679 women were included in the first study (Paper I) and second study (Paper II), respectively. The third study (Paper III) was part of the BASIC study, a large cohort following women from pregnancy and up to one year postpartum. In BASIC, the women completed web-questionnaires, and 1217 women participated during mid-pregnancy and postpartum. The fourth study (Paper IV) was part of a qualitative project, “Narratives of breastfeeding”, and included 11 women, interviewed individually in late pregnancy.The prevalence of the hands-on approach was 38%. Women who received the hands-on approach were more likely to report a negative experience of the first breastfeeding session (Paper I). Seventy-seven percent of the women reported exclusive breastfeeding up to, at least, two months postpartum. Being a first-time mother, reporting emotional distress during pregnancy, and giving birth by cesarean section were factors independently associated with exclusive breastfeeding lasting less than two months postpartum (Paper II). Women with depressive symptoms during pregnancy who breastfed for the first time later than two hours postpartum had the highest odds of not breastfeeding exclusively at six weeks postpartum (Paper III). When pregnant women thought about their future breastfeeding, they were balancing between social norms and personal desires (Paper IV).These results can help to develop clinical practice to improve women’s experience of the first breastfeeding session. Additionally, the results may facilitate identifying women in need for targeted support, in order to promote longer exclusive breastfeeding duration. By acknowledging pregnant women’s thoughts and attitudes about breastfeeding, breastfeeding information and support, health care professionals can meet the needs and desires of women.

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- AbstractCato, K. 2015 The first breastfeeding session: studies on caregivers’ support and breastfeeding duration. 33pp. Uppsala. ISBN 978-91-506-2494-6 It is well-known that the first breastfeeding session can be essential for breastfeeding duration. The hands-on approach given by health care professionals, where health care professionals touch the woman’s breast and the baby in order to stimulate latch on and breastfeeding, has been described as awkward and disturbing. The aim of this thesis was to increase knowledge on the first breastfeeding session postpartum, as to frequency and experience of the hands-on approach, and possible correlates of shorter breastfeeding duration. Questionnaires were sent five days, six weeks and six months postpartum, including questions regarding breastfeeding initiation and duration. Eight hundred and fifty-four women and 679 women were included in Study I and Study II, respectively. The prevalence of the hands-on approach was 38%. Women who received the hands-on approach were more likely to report a negative experience of the first breastfeeding session (Study I). Seventy-seven percent of the women reported exclusive breastfeeding at two months postpartum. Being a first time mother, reporting emotional distress during pregnancy and giving birth by cesarean section were factors independently associated with exclusive breastfeeding less than two months postpartum (Study II). These results can help to develop clinical practice, in order to improve women’s experience of the first breastfeeding session and identifying women in need of targeted, individualized support, to be able to promote longer exclusive breastfeeding duration.

- IntroductionWomen undergoing fertility treatment experience high levels of stress. However, it remains uncertain if and how stress influences in vitro fertilization (IVF) cycle outcome. This study aimed to investigate whether self-reported perceived and infertility-related stress and cortisol levels were associated with IVF cycle outcomes.Material and methodsA prospective cohort of 485 women receiving fertility treatment was recruited from September 2011 to December 2013 and followed until December 2014. Data were collected by online questionnaire prior to IVF start and from clinical charts. Salivary cortisol levels were measured. Associations between stress and cycle outcomes (clinical pregnancy and indicators of oocyte and embryo quality) were measured by logistic or linear regression, adjusted for age, body mass index, education, smoking, alcohol and caffeine consumption, shiftwork and night work. ResultsUltrasound verified pregnancy rate was 26.6% overall per cycle started and 32.9% per embryo transfer. Stress measures were not associated with clinical pregnancy: when compared with the lowest categories, the adjusted odds ratio (OR) and 95% confidence interval (CI) for the highest categories of the perceived stress score was 1.04 (95% CI 0.58-1.87), infertility-related stress score was OR = 1.18 (95% CI 0.56-2.47), morning and evening cortisol was OR = 1.18 (95% CI 0.60-2.29) and OR = 0.66 (95% CI 0.34-1.30), respectively.ConclusionsPerceived stress, infertility-related stress, and cortisol levels were not associated with IVF cycle outcomes. These findings are potentially reassuring to women undergoing fertility treatment with concerns about the influence of stress on their treatment outcome.

- Pregnancy is a period characterized by a supraphysiological hormonal status, and greater anxiety proneness, which can lead to peripartum affective symptoms with dramatic consequences not only for the woman but also for the child. Clinical psychiatry is heavily hampered by the paucity of objective and biology-based intermediate phenotypes. Prepulse inhibition (PPI) of the startle response, a neurophysiological measure of sensorimotor gating, has been poorly investigated in relation to anxiety and in pregnant women. In the present study, the PPI of healthy non-pregnant women (n=82) and late pregnant women (n=217) was investigated. Age, BMI, depression and anxiety symptoms, tobacco use, and antidepressant medication were considered. We investigated and provided evidence of lower PPI: (i) in healthy pregnant women compared to healthy non-pregnant controls, (ii) in pregnant women with anxiety disorders compared to healthy pregnant women, (iii) in pregnant women with anxiety disorders using SSRI compared to un-medicated pregnant women with anxiety disorders, and (iv) in healthy pregnant women carrying the COMT Val158Met Val/Val genotype compared to Met carriers. Altogether, a reduced sensorimotor gating as an effect of supraphysiological hormonal status, anxiety disorders, SSRIs, and catecholaminergic genotype, implicate the putative relevance of lower PPI as an objective biological correlate of anxiety proneness in pregnant women. These findings call for prospective studies to dissect the multifactorial influences on PPI in relation to mental health of pregnant women.

- INTRODUCTION: Although a number of perinatal factors have been implicated in the etiology of postpartum depression, the role of mode of delivery remains controversial. Our aim was to explore the association between mode of delivery and postpartum depression, considering the potentially mediating or confounding role of several covariates. MATERIAL AND METHODS: In a longitudinal-cohort study in Uppsala, Sweden, with 3888 unique pregnancies followed up postpartum, the effect of mode of delivery (spontaneous vaginal delivery, vacuum extraction, elective cesarean section, emergency cesarean section) on self-reported postpartum depression symptoms (Edinburgh Postnatal Depression Scale >/=12) at 6 weeks postpartum was investigated through logistic regression models and path analysis. RESULTS: The overall prevalence of postpartum depression was 13%. Compared with spontaneous vaginal delivery, women who delivered by emergency cesarean section were at higher risk for postpartum depression 6 weeks after delivery in crude (odds ratio 1.45, 95% confidence interval 1.04-2.01) but not in adjusted analysis. However, the path analysis revealed that emergency cesarean section and vacuum extraction were indirectly associated with increased risk of postpartum depression, by leading to postpartum complications, self-reported physical symptoms postpartum, and therefore a negative delivery experience. In contrast, history of depression and fear of delivery increased the odds of postpartum depression and led more frequently to elective cesarean section; however, it was associated with a positive delivery experience. CONCLUSIONS: Mode of delivery has no direct impact on risk of postpartum depression; nevertheless, several modifiable or non-modifiable mediators are present in this association. Women delivering in an emergency setting by emergency cesarean section or vacuum extraction, and reporting negatively experienced delivery, constitute a high-risk group for postpartum depression.

Perinatal Complications: Associations with Postpartum depressive symptoms and Neuroticism
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Even though most pregnancies and deliveries are uncomplicated, still fifteen percent of all women in developed countries suffer pregnancy-related complications. The aim of this thesis was to explore the associations between perinatal complications and perinatal maternal health, with emphasis on postpartum depressive symptoms (PPDS) and neuroticism taking into account potential confounding or mediating factors such as history of depression, antenatal depressive symptoms and delivery experience.In the first study (n=446), the association between heavy postpartum haemorrhage and PPDS at six weeks postpartum was delineated by using path-analysis in order to provide insight into the complex mediating roles of several consequences of postpartum haemorrhage. There was no direct association between postpartum haemorrhage and PPDS, only an indirect one via anaemia at discharge and negative delivery experience.The second study (n=3888) examined the association of mode of delivery with PPDS at 6 weeks postpartum. The results indicate that the association between elective caesarean section and PPDS is highly confounded by history of depression and fear of delivery, while emergency caesarean section and vacuum extraction increase odds for PPDS by leading to postpartum complications and negative delivery experience.The third study (n=1503) investigated the association between the use of epidural analgesia during delivery and PPDS. A positive association in the crude analysis was no longer present after adjustment for sociodemographic, psychosocial and obstetrical variables, indicating that pain relief through epidural analgesia is not likely to affect risk for PPDS.In the last study (n=1969), the association between neuroticism and perinatal complications was explored. Neuroticism was not associated with adverse perinatal outcomes, except for gestational diabetes mellitus. The association, however, became statistically non-significant after adjusting for psychiatric morbidity.In summary, the current studies do no find evidence for a direct association between perinatal complications and postpartum depressive symptoms or neuroticism. However, several important mediators have been identified, among which postpartum anaemia and negative delivery experience deserve special attention. Also, earlier psychiatric history needs to be addressed as an important confounder.

- BackgroundBiased information processing in attention, memory, and interpretation is proposed to be central cognitive alterations in patients with major depressive disorder, but studies in women with peripartum depression are scarce. Because of the many similarities with depression in nonperipartum states as regards symptom profile and risk factors, we hypothesized that women with antenatal and postpartum depression would display attentional bias to negatively and positively valenced words. MethodsOne hundred and seventy-seven pregnant and 157 postpartum women were included. Among these, 40 suffered from antenatal depressive disorder and 33 from postpartum depressive disorder. An emotional Stroop task with neutral, positive, negative, and negatively valenced obstetric words was used. ResultsNo significant difference in emotional interference scores was noted between women with antenatal depression and nondepressed pregnant women. In contrast, women with postpartum depression displayed shorter reaction times to both positive (p=.028) and negative (p=.022) stimuli, compared with neutral words. Pregnant women on antidepressant treatment displayed longer reaction times to negatively valenced obstetric words in comparison with untreated depressed women (p=.012), and a trend toward greater interference in comparison with controls (p=.061). ConclusionsIn contrast with the hypothesis, we found no evidence of attentional bias to emotionally valenced stimuli in women with untreated peripartum depression. However, the shorter reaction times to emotional stimuli in women with postpartum depression may indicate emotional numbing, which in turn, is a functional impairment that may have repercussions for child development and well-being. Our findings emphasize the need to identify and treat women with postpartum depression at the earliest possible time point to ensure swift recovery and support for the family.
