Journal article (peer-reviewed)abstract
- Nausea and vomiting of pregnancy (NVP) is a common condition reported however inconclusively among pregnancies after assisted conception. The study objective was thus to explore whether NVP is associated to mode of conception or other in vitro fertilization (IVF)-related variables. This nested matched cohort study, originating from the BASIC-project, was conducted at the Uppsala University Hospital in Sweden between 2010 and 2016. IVF pregnancies (n=210) and age and parity-matched women with spontaneous pregnancies (n=420) comprised the study sample. The study outcome was self-reported NVP at gestational week 17. IVF treatment and pregnancy data were obtained after scrutinization of the medical records. NVP with or without medications was not associated with mode of conception (chi-square test, p=0.889), even after adjusting for potential confounders. In a subgroup analysis among IVF pregnancies, NVP without medication was more frequently seen in the group who received cleavage stage embryos vs blastocysts (chi-square test, p=0.019), exhibiting a marginally significant but strongly increased effect even after adjustment [crude RRR 3.82 (95% CI 1.23-11.92) and adjusted RRR 3.42 (95% CI 0.96-12.11)]. No difference in the rate of NVP with or without medication between women that underwent fresh and frozen/thawed embryo transfers as well as IVF or ICSI was observed. Conception through IVF is not associated with NVP. Transfer of a blastocyst may decrease the risk of developing NVP and further, large-scale prospective studies are required to validate this finding.

Journal article (peer-reviewed)abstract
- Postpartum depression (PPD) is a detrimental health condition that affects 12% of new mothers. Despite negative effects on mothers' and children's health, many women do not receive adequate care. Preventive interventions are cost-efficient among high-risk women, but our ability to identify these is poor. We leveraged the power of clinical, demographic, and psychometric data to assess if machine learning methods can make accurate predictions of postpartum depression. Data were obtained from a population-based prospective cohort study in Uppsala, Sweden, collected between 2009 and 2018 (BASIC study, n = 4313). Sub-analyses among women without previous depression were performed. The extremely randomized trees method provided robust performance with highest accuracy and well-balanced sensitivity and specificity (accuracy 73%, sensitivity 72%, specificity 75%, positive predictive value 33%, negative predictive value 94%, area under the curve 81%). Among women without earlier mental health issues, the accuracy was 64%. The variables setting women at most risk for PPD were depression and anxiety during pregnancy, as well as variables related to resilience and personality. Future clinical models that could be implemented directly after delivery might consider including these variables in order to identify women at high risk for postpartum depression to facilitate individualized follow-up and cost-effectiveness.

- OBJECTIVE: Women's levels of resilience and attitudes towards perineal lacerations vary greatly. Some women see them as part of the birthing process, while others react with anger, depressed mood or even self-harm thoughts. A previous study has reported increased risk of postpartum depressive (PPD) symptoms in women with severe perineal lacerations. The aim of this study was to assess the association between severe obstetric perineal lacerations and PPD. A secondary objective was to assess this association among women with low resilience.DESIGN: Nested cohort study.SETTING: Uppsala, Sweden.SAMPLE: Vaginally delivered women with singleton pregnancies (n = 2,990).METHODS: The main exposure was obstetric perineal lacerations. Resilience was assessed in gestational week 32 using the Swedish version of the Sense of Coherence Scale (SOC-29). A digital acyclic graph (DAG) was used to identify possible confounders and mediators. Logistic regression was used to estimate odds ratios and 95% confidence intervals. A sub-analysis was run after excluding women with normal or high resilience.MAIN OUTCOME MEASURES: Postpartum depression, assessed with the Depression Self-Reporting Scale (DSRS), completed at six weeks postpartum.RESULTS: There was no significant association between severe obstetric perineal lacerations and PPD at six weeks postpartum. However, a significant association was found between severe lacerations and PPD in women with low resilience (OR =4.8 95% CI = 1.2-20), persisting even after adjusting for confounding factors.CONCLUSION: Health care professionals might need to identify women with low resilience, as they are at increased risk for PPD after a severe perineal laceration.

Journal article (peer-reviewed)abstract
- 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.

Journal article (peer-reviewed)abstract
- IntroductionGender affirming surgery of primary and/or secondary sex characteristics has been shown to alleviate gender dysphoria. A descriptive snapshot of current treatment preferences is useful to understand the needs of the transgender population seeking health care. This study aimed to describe preferences for gender affirming treatment, and their correlates, among individuals seeking health care for gender dysphoria in Sweden after major national legislative reforms.MethodsCross-sectional study where transgender patients (n = 232) recruited from all six Gender Dysphoria centers in Sweden 2016–2019, answered a survey on treatment preferences and sociodemographic, health, and gender identity-related information during the same time-period. Factors associated with preferring top surgery (breast augmentation or mastectomy), genital surgery, and other surgery (e.g., facial surgery) were examined in univariable and multivariable regression analyses in the 197 people without prior such treatment. Main study outcomes were preferences for feminizing or masculinizing hormonal and surgical gender affirming treatment.ResultsThe proportion among birth assigned male and assigned female patients preferring top surgery was 55.6% and 88.7%, genital surgery 88.9% and 65.7%, and other surgery (e.g., facial surgery) 85.6% and 22.5%, respectively. Almost all participants (99.1%) wanted or had already received hormonal treatment and most (96.7%) wished for some kind of surgical treatment; 55.0% wanted both top and genital surgery. Preferring a binary pronoun (he/she) and factors indicating more severe gender incongruence were associated with a greater wish for surgical treatment. Participants with somatic comorbidities were less likely to want genital surgery, while aF with lacking social support were less likely to want internal genital surgery, in the multivariable analyses.ConclusionsIn this sample of Swedish young adults seeking health care for gender dysphoria, preferences for treatment options varied according to perceived gender identity.Policy ImplicationsThe study fndings underline the need for individualized care and fexible gender afrming treatmentoptions. The role of somatic comorbidities should be further explored, and support should be ofered to transgender peoplein need. There is an unmet need for facial surgery among aM

Journal article (peer-reviewed)abstract
- The aim of this study was to investigate sexual behavior, contraceptive use, risk factors as well as sources of sex information among first-year high-school students in Sweden. Secondly, to assess differences between genders and study programs as well as changes over a 40-year period. A repeated cross-sectional survey was conducted in two cities. A questionnaire comprising 77 items was used. The study population consisted of 415 students (63.4% females). The median age of sexual intercourse was 15 years. In total, 37% had had sexual intercourse, compared to 56.3% in 2009 and 45% in 1999 (p < 0.001), and the proportion of students who had their first sexual intercourse was not influenced by gender. More students in vocational programs (46.3%), compared to theoretical (33.3%), had experience of at least one sexual intercourse (p = 0.019). The same extend of contraception use at first and latest intercourse was reported, compared to previous studies. Forty-nine percent were mostly informed about sex from the internet, while in previous years, magazines, family and youth clinics were the main information sources. Comparing over time, students were in general less sexually experienced and less engaged in non-penetrative sex and physical intimacy. These findings call for a new approach, when designing sex and relationship education and health-care counseling in adolescents.

Journal article (peer-reviewed)abstract
- OBJECTIVEAdipocytokines participate in the regulation of glucose metabolism and foetal development. The transcription factor activating protein 2B (TFAP2β) has been associated with adipocytokine regulation, and gene variations with type 2 diabetes and obesity. This study investigated associations between maternal TFAP2B variation, adipocytokines levels and maternal and neonatal anthropometric characteristics.DESIGN AND METHODSA population-based sample of women was followed from delivery to six months postpartum. Adiponectin, leptin and interleukin-6 levels at delivery, and maternal as well as neonatal anthropometric variables were assessed. The TFAP2β intron 1 variable number tandem repeat (VNTR) was genotyped.RESULTSMaternal interleukin-6 correlated positively with leptin at delivery, with peripartum weight changes and weight of newborn males, adjusted for potential confounders. Leptin at delivery was associated with TFAP2β intron 1 VNTR genotype, adjusted for confounders, maternal weight and negatively with birth weight among female neonates. A path model suggested a link between TFAP2β genotype, leptin levels and newborn females' weight.CONCLUSIONSThe present results stress a role for the TFAP2 β in adiposity-related conditions and intrauterine growth. The association between neonatal birth weight and maternal adipocytokine levels, together with the observed sex effect, call for further studies on the mechanisms behind neuro-endocrine foetal programming.

In: European journal of contraception & reproductive health care. - : Taylor & Francis. - 1362-5187 .- 1473-0782. ; 26:4, s. 312-322
-
Journal article (peer-reviewed)abstract
- Purpose: The aim of this study was to investigate medical undergraduate students' fertility awareness and parenthood intentions in three European countries, as well as possible differences across genders and countries.Materials and methods: A cross sectional survey among 656 medical students in Sweden, Belgium and Greece. The utilised questionnaire comprised 23 questions.Results: Three fourth of participants (n = 472/629) correctly stated that women are most fertile at 20-25 years of age. Approximately 91% correctly answered that women's fertility starts to significantly decline before the age of 35, which differed among countries of participation. Social oocyte or sperm freezing was considered by 67% of Belgians, 49% Greeks, and 16.5% Swedes (p < 0.001). Approximately 95% expressed a wish of having a child in the future and the median age was 29 years for the first and 35 years for the last child.Conclusions: Knowledge about fertility among medical students was in general satisfactory, albeit varying by country and gender. Medical curricula and social policies for childbearing should be respectively updated in EU countries suffering population growth.

Journal article (peer-reviewed)abstract
- 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.
