- BackgroundDepressive symptoms negatively impact on breastfeeding duration, whereas early breastfeeding initiation after birth enhances the chances for a longer breastfeeding period. Our aim was to investigate the interplay between depressive symptoms during pregnancy and late initiation of the first breastfeeding session and their effect on exclusive breastfeeding at six weeks postpartum.MethodsIn a longitudinal study design, web-questionnaires including demographic data, breastfeeding information and the Edinburgh Postnatal Depression Scale (EPDS) were completed by 1217 women at pregnancy weeks 17–20, 32 and/or at six weeks postpartum. A multivariable logistic regression model was fitted to estimate the effect of depressive symptoms during pregnancy and the timing of the first breastfeeding session on exclusive breastfeeding at six weeks postpartum.ResultsExclusive breastfeeding at six weeks postpartum was reported by 77% of the women. Depressive symptoms during pregnancy (EPDS> 13); (OR:1.93 [1.28–2.91]) and not accomplishing the first breastfeeding session within two hours after birth (OR: 2.61 [1.80–3.78]), were both associated with not exclusively breastfeeding at six weeks postpartum after adjusting for identified confounders. Τhe combined exposure to depressive symptoms in pregnancy and late breastfeeding initiation was associated with an almost 4-fold increased odds of not exclusive breastfeeding at six weeks postpartum.ConclusionsWomen reporting depressive symptoms during pregnancy seem to be more vulnerable to the consequences of a postponed first breastfeeding session on exclusive breastfeeding duration. Consequently, women experiencing depressive symptoms may benefit from targeted breastfeeding support during the first hours after birth.

Journal article (peer-reviewed)abstract
- Background: Breastfeeding rates in Sweden are declining, and it is important to identify women at risk for early cessation of exclusive breastfeeding.Objective: The aim of this study was to investigate factors associated with exclusive breastfeeding lasting less than two months postpartum.Methods: A population-based longitudinal study was conducted at Uppsala University Hospital, Sweden. Six hundred and seventy-nine women were included in this sub-study. Questionnaires were sent at five days, six weeks and six months postpartum, including questions on breastfeeding initiation and duration as well as several other background variables. The main outcome measure was exclusive breastfeeding lasting less than two months postpartum. Multivariable logistic regression analysis was used in order to calculate adjusted Odds Ratios (AOR) and 95% Confidence Intervals (95% CI).Results: Seventy-seven percent of the women reported exclusive breastfeeding at two months postpartum. The following variables in the multivariate regression analysis were independently associated with exclusive breastfeeding lasting less than two months postpartum: being a first time mother (AOR 2.15, 95% CI 1.32 +/- 3.49), reporting emotional distress during pregnancy (AOR 2.21, 95% CI 1.35 +/- 3.62) and giving birth by cesarean section (AOR 2.63, 95% CI 1.34 +/- 5.17).Conclusions: Factors associated with shorter exclusive breastfeeding duration were determined. Identification of women experiencing emotional distress during pregnancy, as well as scrutiny of caregiving routines on cesarean section need to be addressed, in order to give individual targeted breastfeeding support and promote longer breastfeeding duration.

Journal article (peer-reviewed)abstract
- Fetal scalp blood sampling (FBS) is often claimed to be painful for women in labor and difficult for obstetricians to perform. Our aim was to assess women's experience of pain during FBS and obstetricians' experience of difficulty in performing the test. At a tertiary centre in Sweden, a questionnaire with answers on a ten-point scale was completed by 51 women and by the obstetricians performing the test. Women's experience of pain had a median of 3.5. FBS was well tolerated in women who had epidural analgesia, but might be associated with pain in women without. Higher maternal body mass index and less cervical dilatation were associated with higher pain ratings. Obstetricians did not generally experience scalp sampling as difficult to perform (median score 3.0). However, the sampling procedure can be more complicated in situations with higher maternal body mass, less cervical dilatation, and a higher station of the fetal head.

In: Scientific Reports. - : Springer Science and Business Media LLC. - 2045-2322. ; 11:1
-
Journal article (peer-reviewed)abstract
- Fetal growth restriction is a strong risk factor for perinatal morbidity and mortality. Reliable standards are indispensable, both to assess fetal growth and to evaluate birthweight and early postnatal growth in infants born preterm. The aim of this study was to create updated Swedish reference ranges for estimated fetal weight (EFW) from gestational week 12–42. This prospective longitudinal multicentre study included 583 women without known conditions causing aberrant fetal growth. Each woman was assigned a randomly selected protocol of five ultrasound scans from gestational week 12 + 3 to 41 + 6. Hadlock’s 3rd formula was used to estimate fetal weight. A two-level hierarchical regression model was employed to calculate the expected median and variance, expressed in standard deviations and percentiles, for EFW. EFW was higher for males than females. The reference ranges were compared with the presently used Swedish, and international reference ranges. Our reference ranges had higher EFW than the presently used Swedish reference ranges from gestational week 33, and higher median, 2.5th and 97.5th percentiles from gestational week 24 compared with INTERGROWTH-21st. The new reference ranges can be used both for assessment of intrauterine fetal weight and growth, and early postnatal growth in children born preterm. © 2021, The Author(s).

Journal article (peer-reviewed)abstract
- Ultrasonic assessment of fetal growth is an important part of obstetric care to prevent adverse pregnancy outcome. However, lack of reliable reference ranges is a major barrier for accurate interpretation of the examinations. The aim of this study was to create updated Swedish national reference ranges for intrauterine size and growth of the fetal head, abdomen and femur from gestational week 12 to 42. This prospective longitudinal multicentre study included 583 healthy pregnant women with low risk of aberrant fetal growth. Each woman was examined up to five times with ultrasound from gestational week 12+3 to 41+6. The assessed intrauterine fetal biometric measurements were biparietal diameter (outer-inner), head circumference, mean abdominal diameter, abdominal circumference and femur length. A two-level hierarchical regression model was employed to account for the individual measurements of the fetus and the number of repeated visits for measurements while accounting for the random effect of the identified parameterization of gestational age. The expected median and variance, expressed in both standard deviations and percentiles, for each individual biometric measurement was calculated. The presented national reference ranges can be used for assessment of intrauterine size and growth of the fetal head, abdomen and femur in the second and third trimester of pregnancy.

Journal article (peer-reviewed)abstract
- Antidepressant treatment when facing a pregnancy is an important issue for many women and their physicians. We hypothesized that women with a greater burden of pre-pregnancy psychiatric illness would be more likely to re-initiate antidepressants following discontinuation of treatment during pregnancy. A register-based cohort study was carried out including 38,595 women who gave birth between the 1st of January 2007 and the 31st of December 2014, who had filled a prescription for an antidepressant medication in the year prior to conception. Logistic regressions were used to explore associations between maternal characteristics and antidepressant treatment discontinuation or re-initiation during pregnancy. Most women discontinued antidepressant treatment during pregnancy (n = 29,095, 75.4%), of whom nearly 12% (n = 3434, 11.8%) re-initiated treatment during pregnancy. In adjusted analyses, parous women (aOR 1.22, 95% CI 1.12-1.33), with high educational level (aOR 1.21, 95% CI 1.08-1.36); born within the EU (excluding Nordic countries, aOR 1.41, 95% CI 1.03-1.92) or a Nordic country (aOR 1.42, 95% CI 1.22-1.65); who more often reported prior hospitalizations due to psychiatric disorders (aOR 1.50, 95% CI 1.10-2.03, for three or more episodes); and had longer duration of pre-pregnancy antidepressant use (aOR 6.10, 95% CI 5.48-6.77, for >2 years antidepressant use), were more likely to re-initiate antidepressants than were women who remained off treatment. Women with a greater burden of pre-pregnancy psychiatric illness were more likely to re-initiate antidepressants. Thus, pre-pregnancy psychiatric history may be particularly important for weighing the risks and benefits of discontinuing antidepressants during pregnancy.

Plasma levels of arginines at term pregnancy in relation to mode of onset of labor and mode of childbirth
- 2023
-
In: American Journal of Reproductive Immunology. - : John Wiley & Sons. - 1046-7408 .- 1600-0897. ; 90:3
-
Journal article (peer-reviewed)abstract
- PROBLEM: The exact biochemical mechanisms that initiate labor are not yet fully understood. Nitric oxide is a potent relaxant of uterine smooth muscles until labor starts, and its precursor is L-arginine. Asymmetric (ADMA) and symmetric (SDMA) dimethylarginines, are potent NO-inhibitors. However, arginines (dimethylarginines and L-arginine) are scarcely studied in relation to labor and childbirth. We aimed to investigate arginines in women with spontaneous (SLVB) and induced (ILVB) term labor with vaginal birth and in women undergoing elective caesarean section (ECS).METHOD OF STUDY: Women at gestational week 16-18 were recruited to the population-based prospective cohort study BASIC at the Uppsala University Hospital, Sweden. Plasma samples taken at start of labor were analyzed for arginines, from SLVB (n = 45), ILVB (n = 45), and ECS (n = 45), using Ultra-High Performance Liquid Chromatography. Between-group differences were assessed using Kruskal-Wallis and Mann-Whitney U-test.RESULTS: Women with SLVB and ILVB had higher levels of ADMA (p < .0001), SDMA (p < .05) and lower L-arginines (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01, respectively <.001) compared to ECS. However, ILVB had higher ADMA (p < .0001) and lower L-arginine (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01) compared to SLVB. Results are adjusted for gestational length at birth and cervical dilatation at sampling.CONCLUSION: Our novel findings of higher levels of dimethylarginines in term vaginal births compared to ECS give insights into the biochemical mechanisms of labor. These findings might also serve as a basis for further studies of arginines in complicated pregnancies and labor.

In: Scientific Reports. - : Springer Nature. - 2045-2322. ; 11:1
-
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.

Journal article (peer-reviewed)abstract
- 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.

Social and emotional contexts predict the development of gaze following in early infancy
- 2020
-
In: Royal Society Open Science. - : The Royal Society. - 2054-5703. ; 7:9
-
Journal article (peer-reviewed)abstract
- The development of gaze following begins in early infancy and its developmental foundation has been under heavy debate. Using a longitudinal design (N = 118), we demonstrate that attachment quality predicts individual differences in the onset of gaze following, at six months of age, and that maternal postpartum depression predicts later gaze following, at 10 months. In addition, we report longitudinal stability in gaze following from 6 to 10 months. A full path model (using attachment, maternal depression and gaze following at six months) accounted for 21% of variance in gaze following at 10 months. These results suggest an experience-dependent development of gaze following, driven by the infant's own motivation to interact and engage with others (the social-first perspective).
