  • Anxious personality traits in pregnant women : Associations with postpartum depression, delivery complications and health care use
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Anxious personality traits, including those encompassed by negative emotionality (neuroticism) and the tendency to worry about close relationships (attachment anxiety) during pregnancy were the focus of this thesis. The overall aim was to examine perinatal correlates of these characteris-tics in terms of psychiatric and obstetric health as well as antenatal care (ANC).Papers I-II were part of a large population-based project on pregnant women in Uppsala in 2009-2012 (n=2160). Papers III-IV adjoined participants from several projects in 2005-2011, on oral contraceptive use, infertility, induced abortion, premenstrual mood disorder, and perina-tal depression (n=2819). The participants reported on the Swedish universities Scales of Per-sonality for neuroticism (papers II-IV) and the Attachment Style Questionnaire (ASQ) for attachment anxiety (papers I-II). The participants also answered the Edinburgh Postnatal De-pression Scale on depressive symptoms (paper II). In paper III, information on obstetric com-plications for primiparous women with singleton pregnancies (n=1969) was extracted from Swedish national health registers. In paper IV, ANC use was derived from medical records of obstetric low-risk women residing in Uppsala (n=1052).The ASQ had similar psychometric properties in pregnant women (n=1631) as in previous reports (paper I). In non-depressed pregnant women (n=1431), the combination of neuroticism and attachment anxiety was the best risk indicator of postpartum depressive symptoms (paper II). Whereas high neuroticism was not related to obstetric complications (paper III), it was associated with higher use of ANC (paper IV).Summarized, this thesis illustrates how anxious personality traits may predispose for post-partum depression and higher use of ANC in the absence of obstetric complications. Future development of these findings should be to evaluate individual and societal benefits of a greater emphasis on psychological support in ANC.

  • Biomarkers for Peripartum Depression : Focusing on aspects of the immune system and the metabolome
  • 2021
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Peripartum depression is a common, multifactorial, and potentially devastating disease among new mothers. A biological marker for peripartum depression would facilitate early detection, better understanding of the pathophysiology, and identification of targets for treatment. Evidence is growing for a potential role of the immune system in depression outside the peripartum period. Major adaptations of the immune system occur during pregnancy, justifying the search for immunological markers for peripartum depression. The immune system is very complex and dynamic during pregnancy, complicating the study of associations with depression. The metabolome is also affected by pregnancy and is linked to the immune system via, e.g., the microbiota. Hence, metabolomic profiling could increase the understanding of peripartum depression. This thesis aimed to explore inflammatory markers and metabolic profiles in the peripartum period, in order to discover possible biomarkers, and to increase the understanding of the pathophysiology of peripartum depression.All studies were conducted within the Biology, Affect, Stress, Imaging, and Cognition (BASIC) study. The Edinburgh Postnatal Depression Scale and the Mini International Neuropsychiatric Interview were used to assess depressive symptoms. Multiplex Proximity Extension assays were used to analyze inflammatory markers in pregnancy and postpartum. Luminex Bio-Plex Pro Human Cytokine Assays were used to analyze cytokine levels across the peripartum period, and gas chromatography-mass spectrometry metabolomics were used for metabolic profiling. No marker was discriminative enough to be used on its own as a biomarker for peripartum depression. However, several inflammatory markers (such as STAM-BP, TRANCE, HGF, IL-18, FGF-23, and CXCL1) were identified as possible candidates for more advanced diagnostic algorithms. The results further pointed towards the importance of adaptation of the immune system during pregnancy and postpartum, where levels of cytokines such as VEGF-A might have an important role in antenatal and postpartum depression. The results even highlight the importance of examination timing. Lastly, the metabolic profiling suggested different subgroups of women with postpartum depressive symptoms, supporting theories of peripartum depression being a heterogeneous disease in need of subgroup definition.

  • 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.

  • The first breastfeeding session: studies on caregivers' support and breastfeeding duration
  • 2015
  • 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.

  • 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.
