RESUMO
BACKGROUND: Perinatal depression affects a significant number of women during pregnancy and after birth, and early identification is imperative for timely interventions and improved prognosis. Mobile apps offer the potential to overcome barriers to health care provision and facilitate clinical research. However, little is known about users' perceptions and acceptability of these apps, particularly digital phenotyping and ecological momentary assessment apps, a relatively novel category of apps and approach to data collection. Understanding user's concerns and the challenges they experience using the app will facilitate adoption and continued engagement. OBJECTIVE: This qualitative study explores the experiences and attitudes of users of the Mom2B mobile health (mHealth) research app (Uppsala University) during the perinatal period. In particular, we aimed to determine the acceptability of the app and any concerns about providing data through a mobile app. METHODS: Semistructured focus group interviews were conducted digitally in Swedish with 13 groups and a total of 41 participants. Participants had been active users of the Mom2B app for at least 6 weeks and included pregnant and postpartum women, both with and without depression symptomatology apparent in their last screening test. Interviews were recorded, transcribed verbatim, translated to English, and evaluated using inductive thematic analysis. RESULTS: Four themes were elicited: acceptability of sharing data, motivators and incentives, barriers to task completion, and user experience. Participants also gave suggestions for the improvement of features and user experience. CONCLUSIONS: The study findings suggest that app-based digital phenotyping is a feasible and acceptable method of conducting research and health care delivery among perinatal women. The Mom2B app was perceived as an efficient and practical tool that facilitates engagement in research as well as allows users to monitor their well-being and receive general and personalized information related to the perinatal period. However, this study also highlights the importance of trustworthiness, accessibility, and prompt technical issue resolution in the development of future research apps in cooperation with end users. The study contributes to the growing body of literature on the usability and acceptability of mobile apps for research and ecological momentary assessment and underscores the need for continued research in this area.
RESUMO
OBJECTIVE: To explore men's and women's experiences regarding their history of sexual health when attending a fertility clinic. METHODS: A qualitative study with semi-structured individual interviews was conducted among heterosexual males and females seeking infertility care at a public fertility clinic in Sweden in 2022-2023. The interviews were audio-recorded, transcribed verbatim and analyzed using qualitative content analysis. RESULTS: Eight males and ten females were included. The analysis resulted in an overarching theme: A change from spontaneous to scheduled intercourse affects various aspects of sexual health. In the beginning of the relationship sex had been spontaneous, joyful and satisfying. However, sex was not always unproblematic, and there had been sexual changes. Sex with a reproductive purpose was scheduled according to ovulation, leading to changes in sexual behavior. Increased erectile problems in men and decreased frequency of orgasms in women, and a lack of sexual desire in both, were experienced. Men and women felt pressured to have sex when it became a requirement. Men's sexual and women's reproductive failures led to negative emotional reactions, including stress, frustration, disappointment, anxiety and guilt. Sexual and reproductive problems affected the relational well-being, leading to feelings of sharing the burden but also conflicts and sexual avoidance. CONCLUSIONS: Experiencing reproductive failures, sexual problems and negative emotional reactions can affect men's and women's sexual health. Therefore, an implication for clinical practice among healthcare professionals during evaluation of infertility, is a need to be aware of and ask questions about sexual health after reproductive failures.
RESUMO
BACKGROUND: Postpartum depression affects around 12% of mothers in developed countries, with consequences for the whole family. Many women with depressive symptoms remain undetected and untreated. The aim of this study was to investigate to what extent women with depressive symptoms at 6 weeks postpartum are identified by the healthcare system, the interventions they received, and remission rates at 6 months postpartum. METHODS: Postpartum women scoring 12-30 on the Edinburgh Postnatal Depression Scale (EPDS) at 6 weeks after delivery (n = 697) were identified from the longitudinal cohort study "Biology, Affect, Stress, Imaging and Cognition" (BASIC) in Uppsala, Sweden. A total of 593 women were included. Background and remission information at 6 months was collected from the BASIC dataset. Medical records were examined to identify interventions received. RESULTS: Most women (n = 349, 58.7%) were not identified by the healthcare system as having depressive symptoms and 89% lacked any record of interventions. Remission rates at 6 months postpartum were 69% in this group. Among women identified by the healthcare system, 90% received interventions and about 50% were in remission at 6 months postpartum. The EPDS reduction during the study period was largest in the group identified by the child health services (CHS, -5.15) compared to the non-identified (-4.24, p < 0.001). CONCLUSIONS: Despite screening guidelines, many women with depressive symptoms had no documentation of screening or interventions by the healthcare system. Furthermore, a significant proportion did not achieve remission despite interventions. Being identified by CHS was associated with the largest reduction of symptoms. Research is needed to understand gaps in the healthcare processes, to better identify peripartum depression.

Conservative management of endometrial cancer (CMEC) is viable for women with early-stage disease wishing to preserve fertility, but there is poor knowledge regarding clinicians' attitudes towards treatment or guidelines adherence. This 55-item survey study investigated CMEC-related experience, practice and attitudes among clinically active Swedish gynecologists and gynecological oncologists, focusing on reproductive eligibility criteria. The survey consisted of a general and two specific subsets, selectively delivered to clinicians active in infertility (subset A) and endometrial cancer (subset B) care. Answers from 218 clinicians were included. More than half agreed on CMEC whereas only 5% explicitly disagreed. The majority supported a fertility work-up to substantiate reasonable chances to pregnancy and live birth. Most disagreed about CMEC in case of previous unsuccessful fertility treatments, while more than 1/3 disagreed about CMEC in known fertility problems, recurrent miscarriages or previous children. Over 50% of respondents in subset A (n = 107) found it applicable with fertility investigations such as ovarian reserve testing or, in case of male partner, semen analysis. Respondents in subset B (n = 165) agreed on items based on existing recommendations regarding the oncological management of CMEC, including the use of continuous progestins, hysteroscopic resection of macroscopic lesions, control biopsy with curettage or hysteroscopy after 6 months of treatment, pursuing pregnancy as soon as possible after complete response, and performing a hysterectomy once live birth is achieved. While many clinicians were familiar with CMEC, the overall experience is limited. Fertility specialists seem less involved than oncologists in patient care but there is broad support for fertility-related eligibility criteria.

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.

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.

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.

The Transgender Congruence Scale (TCS) is a non-binary tool used in Sweden for gender dysphoria (GD) assessment; however, its Swedish version has not been validated. To investigate the psychometric properties of the TCS, its capacity to distinguish individuals with GD and its concurrent validity compared to other scales. Patients with GD (n = 135) and controls (n = 443) filled in a questionnaire containing sociodemographic questions, the TCS, the Utrecht Gender Dysphoria Scale (UGDS), and the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA). TCS had good discriminatory validity and internal consistency. Patients with GD, stratified by birth-assigned sex, had lower TCS scores compared to controls. Confirmatory factor analysis (CFA) supported the two-factor model of the TCS. Multiple-group CFA suggested measurement invariance between birth-assigned sexes and configural invariance between patients with GD and controls. Area under the ROC curve for birth-assigned males was 0.991 and for females 0.994. A TCS mean value of three provided sensitivity 94.3% and 95.1% as well as specificity 98.6% and 98% for aM and aF, respectively. The TCS was significantly correlated to UGDS and GIDYQ-AA. The TCS may be a valuable tool in the clinical assessment of individuals with GD.

Maternal perinatal depression (PND), a common mental disorder with a prevalence of over 10%, is associated with long-term health risks for both mothers and offspring. This study aimed at describing characteristics related to background and lifestyle, pregnancy, delivery, and postpartum of different PND trajectories defined according to the onset of depressive symptoms. Participants were drawn from a large population-based cohort study in Uppsala, Sweden (n = 2,466). Five trajectory groups of depressive symptom onset were created using the Edinburgh Postnatal Depression Scale ≥13 (pregnancy) or ≥12 points (postpartum): (a) healthy (60.6%), (b) pregnancy depression (8.5%), (c) early postpartum onset (10.9%), (d) late postpartum onset (5.4%), and (e) chronic depression (14.6%). In multinomial logistic regressions, the associations between trajectories and the included characteristics were tested using the healthy trajectory as reference. Background characteristics (younger age, lower education, unemployment) were primarily associated with pregnancy depression and chronic depression. Characteristics associated with all PND trajectories were smoking prior to pregnancy, migraine, premenstrual mood symptoms, intimate partner violence, interpersonal trauma, negative delivery expectations, pregnancy nausea, and symphysiolysis. Nulliparity, instrumental delivery, or a negative delivery experience was associated with early postpartum onset. Postpartum factors (e.g., infantile colic, lack of sleep, low partner support, and bonding difficulties) were associated with early and late postpartum onset together with chronic depression. The findings suggest that different PND trajectories have divergent characteristics, which could be used to create individualized treatment options. To find the most predictive characteristics for different PND trajectories, studies with even larger and more diverse samples are warranted.

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.

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.

Antenatal depression affects ~9-19% of pregnant women and can exert persistent adverse effects on both mother and child. There is a need for a deeper understanding of antenatal depression mechanisms and the development of tools for reliable diagnosis and early identification of women at high risk. As the use of untargeted blood metabolomics in the investigation of psychiatric and neurological diseases has increased substantially, the main objective of this study was to investigate whether untargeted gas chromatography-mass spectrometry (GC-MS) plasma metabolomics in 45 women in late pregnancy, residing in Uppsala, Sweden, could indicate metabolic differences between women with and without depressive symptoms. Furthermore, seasonal differences in the metabolic profiles were explored. When comparing the profiles of cases with controls, independently of season, no differences were observed. However, seasonal differences were observed in the metabolic profiles of control samples, suggesting a favorable cardiometabolic profile in the summer vs. winter, as indicated by lower glucose and sugar acid concentrations and lactate to pyruvate ratio, and higher abundance of arginine and phosphate. Similar differences were identified between cases and controls among summer pregnancies, indicating an association between a stressed metabolism and depressive symptoms. No depression-specific differences were apparent among depressed and non-depressed women, in the winter pregnancies; this could be attributed to an already stressed metabolism due to the winter living conditions. Our results provide new insights into the pathophysiology of antenatal depression, and warrant further investigation of the use of metabolomics in antenatal depression in larger cohorts.

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.

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.

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.
RESUMO
BACKGROUND: Peripartum depression is a common cause of pregnancy- and postpartum-related morbidity. The production of corticotropin-releasing hormone (CRH) from the placenta alters the profile of hypothalamus-pituitary-adrenal axis hormones and may be associated with postpartum depression. The purpose of this study was to assess, in nondepressed pregnant women, the possible association between CRH levels in pregnancy and depressive symptoms postpartum. METHODS: A questionnaire containing demographic data and the Edinburgh Postnatal Depression Scale (EPDS) was filled in gestational weeks 17 and 32, and 6 week postpartum. Blood samples were collected in week 17 for assessment of CRH. A logistic regression model was constructed, using postpartum EPDS score as the dependent variable and log-transformed CRH levels as the independent variable. Confounding factors were included in the model. Subanalyses after exclusion of study subjects with preterm birth, newborns small for gestational age (SGA), and women on corticosteroids were performed. RESULTS: Five hundred thirty-five women without depressive symptoms during pregnancy were included. Logistic regression showed an association between high CRH levels in gestational week 17 and postpartum depressive symptoms, before and after controlling for several confounders (unadjusted OR = 1.11, 95% CI 1.01-1.22; adjusted OR = 1.13, 95% CI 1.02-1.26; per 0.1 unit increase in log CRH). Exclusion of women with preterm birth and newborns SGA as well as women who used inhalation corticosteroids during pregnancy did not alter the results. CONCLUSIONS: This study suggests an association between high CRH levels in gestational week 17 and the development of postpartum depressive symptoms, among women without depressive symptoms during pregnancy.
RESUMO
BACKGROUND: The biology of peripartum depression remains unclear, with altered stress and the Hypothalamus-Pituitary-Adrenal axis response having been implicated in its pathophysiology. METHODS: The current study was undertaken as a part of the BASIC project (Biology, Affect, Stress, Imaging, Cognition), a population-based longitudinal study of psychological wellbeing during pregnancy and the postpartum period in Uppsala County, Sweden, in order to assess the association between evening salivary cortisol levels and depressive symptoms in the peripartum period. Three hundred and sixty-five pregnant women from the BASIC cohort were recruited at pregnancy week 18 and instructed to complete a Swedish validated version of the Edinburgh Postnatal Depression Scale at the 36th week of pregnancy as well as the sixth week after delivery. At both times, they were also asked to provide evening salivary samples for cortisol analysis. A comprehensive review of the relevant literature is also provided. RESULTS: Women with postpartum EPDS score ≥ 10 had higher salivary evening cortisol at six weeks postpartum compared to healthy controls (median cortisol 1.19 vs 0.89 nmol/L). A logistic regression model showed a positive association between cortisol levels and depressive symptoms postpartum (OR = 4.1; 95% CI 1.7-9.7). This association remained significant even after controlling for history of depression, use of tobacco, partner support, breastfeeding, stressful life events, and sleep problems, as possible confounders (aOR = 4.5; 95% CI 1.5-14.1). Additionally, women with postpartum depressive symptoms had higher postpartum cortisol levels compared to both women with depressive symptoms antenatally and controls (p = 0.019 and p = 0.004, respectively). CONCLUSIONS: Women with depressive symptoms postpartum had higher postpartum cortisol levels, indicating an altered response of the HPA-axis in postpartum depression.

OBJECTIVE: Adipocytokines participate in the regulation of glucose metabolism and fetal development. The transcription factor activating protein 2B (TFAP2ß) has been associated with adipocytokine regulation, and gene variations with type 2 diabetes and obesity. This study investigated associations between maternal TFAP2B variation, adipocytokine levels, and maternal and neonatal anthropometric characteristics. DESIGN AND METHODS: A population-based sample of women was followed from delivery to 6 months postpartum. Adiponectin, leptin, and interleukin-6 levels at delivery, and maternal as well as neonatal anthropometric variables were assessed. The TFAP2ß intron 1 variable number tandem repeat (VNTR) was genotyped. RESULTS: Maternal 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 TFAP2ß intron 1 VNTR genotype, adjusted for confounders, maternal weight and negatively with birth weight among female neonates. A path model suggested a link between TFAP2ß genotype, leptin levels, and newborn females' weight. CONCLUSIONS: The present results stress a role for the TFAP2 ß 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 neuroendocrine fetal programming.
