Assisted reproductive technologies are slightly associated with maternal lack of affection toward the newborn: The Japan Environment and Children's Study

Neonatal transfer and duration of hospitalization of newborns as potential risk factors for impaired mother-infant bonding: The Japan Environment and Children's Study

BACKGROUND

Currently, there is no consensus regarding the relationship between neonatal transfer and duration of hospitalization in cases of impaired mother-infant bonding (MIB). This study aimed to determine whether neonatal transfer and duration of hospitalization of newborns increase the risk for impaired MIB.

METHODS

The MIB Scale was used to assess impaired MIB 1 year after delivery, using data from the Japan Environment and Children's Study. A score ≥ 5 points indicated impaired MIB. Multiple logistic regression analyses were performed to estimate the association between neonatal transfer and duration of hospitalization of newborns with the risk of impaired MIB.

RESULTS

A total of 66,402 pregnant women were included in the study. The overall incidence rate of impaired MIB was 11.2 %. The mean duration of hospitalization of newborns was 7.1 ± 6.4 days. After adjusting for potential confounders, neonatal transfer (adjusted odd ratio (OR): 1.13 [95 % confidence interval (CI)), 1.01-1.27]) and duration of hospitalization of newborns (adjusted OR 1.007; 95 % CI 1.003-1.010) were associated with impaired MIB. The area under the receiver operating characteristic curve for the duration of hospitalization of newborns for impaired MIB was 0.53.

LIMITATIONS

Maternal childhood abuse and neglect history were not evaluated, and information regarding whether the infants were admitted to the neonatal intensive care unit was unavailable.

CONCLUSIONS

Japanese women whose newborns underwent neonatal transfer should be followed up for at least 1 year after delivery, regardless of the duration of hospitalization of newborns.

Two babies, two bonds: Frequency and correlates of differential maternal-infant bonding in mothers of twins

We assessed prevalence and correlates of differential maternal-infant bonding (i.e., experiencing a stronger bond with one baby vs. the other) in mothers of twins, focusing on aspects of maternal mental health, well-being, and pregnancy/birth that have been previously linked with maternal-infant bonding. Participants (N = 108 American women, 88.89% White, 82.41% non-Hispanic, aged 18-45, who gave birth to twins in the past 6-24 weeks) were recruited from postpartum support websites. Participants completed a Qualtrics survey assessing pregnancy/birth history, symptoms of depression and anxiety, sleep, stress, romantic relationship satisfaction, and postpartum bonding. Twenty-six participants (24.07%) reported a bonding discrepancy. These participants endorsed higher symptoms of depression and anxiety, lower relationship satisfaction, lower average postpartum bonding, higher general and parenting stress, and longer pregnancy (all ps > .05). Greater degree of bonding discrepancy correlated with more depression, higher parenting stress, longer pregnancy, and lower relationship satisfaction (all ps > .05). Mothers of twins may benefit from postpartum mental health support, stress management strategies, and interventions to improve bonding. Future work should assess the role of breastfeeding difficulties, delivery method, birth-related trauma, infant regulatory capacity, and temperament. Longitudinal studies will help test cause and effect and potential long-term repercussions of maternal-infant bonding discrepancies.

First-Time Parents' Bonding with Their Baby: A Longitudinal Study on Finnish Parents during the First Eight Months of Parenthood

Early positive bonding between parents and babies promotes the development of parenting skills and parents' sensitivity to their infant's needs. Positive bonding has been suggested to decrease the risk of maltreatment. There is less research into the differences between primiparae's and their spouses' bonding with their baby and changes in the parent-to-infant bonding during the first year of the baby's life. The aim of this study was to describe bonding with one's baby and related differences and changes within first-time parents. The data were collected from nine maternal health clinics in 2019-2021 in one city in Finland. The Mother-to-Infant Bonding Scale (MIBS) and the Edinburgh Postnatal Depression Scale (EPDS) were used. The data were collected during pregnancy (T1) and when the baby was aged 1-2 months (T2) and 6-8 months (T3). The questionnaire was completed separately by the primiparae (n = 81 at T1) and their spouses (n = 79 at T1). The findings demonstrated that both parents had positive feelings for their baby. The primiparae's and their spouses' MIBS scores were relatively low at T2 and T3. The change between time points or the difference in the parents' bonding was not statistically significant when examining MIBS total scores. The present study identified a positive weak-to-moderate correlation between the MIBS and EPDS. This association was highlighted in the group of primiparae. The results of this study can be used to develop maternity and child health clinic services, and to promote parents' equal growth in parenthood.

Antenatal predictors of postnatal maternal attachment and competence after assisted conception-a prospective cohort study in South India

The aim of this study is to examine the influence of antenatal factors such as anxiety, depression, perceived stress, marital satisfaction, maternal antenatal attachment, and social support on postnatal maternal attachment and competence in women who received assisted reproductive treatment. A prospective longitudinal cohort design was adopted with two groups-50 women who received assisted reproductive treatment and 50 women who had natural conception. Both the groups were assessed using self-report measures over three time points: T1, 7th month of pregnancy; T2, 2 weeks postpartum; and T3, 3 months postpartum. A final sample of 44 women who had assisted conception and 47 women who had natural conception completed assessments across all three time points. Descriptive, bivariate analyses, and stepwise multiple linear regression analyses were carried out. In the assisted conception group, maternal antenatal attachment, depression, and marital satisfaction significantly predicted postnatal maternal-infant attachment. Perceived social support, depression, and duration of marriage significantly predicted postnatal maternal competence. In the naturally conceived group, maternal antenatal attachment and social support significantly predicted postnatal maternal-infant attachment; perceived stress significantly predicted postnatal maternal competence. Antenatal depressive symptoms and relational factors significantly influenced postnatal maternal attachment and competence highlighting the need for screening and targeted psychological interventions during pregnancy.

Neurological development in 36‐month‐old children conceived via assisted reproductive technology: The Japan Environment and Children's Study

Purpose

This study aimed to investigate neurodevelopment in children conceived via in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) with several types of embryo transfers.

Methods

We analyzed data for 77 928 children and their mothers included in a Japanese birth cohort study. Among the included children, 4071 were conceived via IVF, while 1542 were conceived via ICSI. Neurodevelopmental delay at the age of 3 years was assessed using the Japanese version of the Ages and Stages Questionnaires, 3rd edition.

Results

In the crude model, the odds ratios for developmental delay in 1–4 domains were higher among children conceived via IVF, ICSI, and non‐ART (ovulatory induction or intrauterine insemination) than in spontaneously conceived children. After adjusting for parental background factors and the child's sex, there were no differences in the risk of developmental delay when comparing singletons conceived by IVF, ICSI, or non‐ART and those conceived spontaneously. Higher odds ratios for developmental delay in one domain were observed in singleton girls conceived via IVF when compared with those who were spontaneously conceived.

Conclusion

Most cases of developmental delay may be associated with multiple pregnancies and factors related to infertility, such as parental age, irrespective of the use of ART.

The value of transvaginal 4-dimensional hysterosalpingo-contrast sonography in predicting the necessity of assisted reproductive technology for women with tubal factor infertility

Background

More than 50 million women suffer from infertility worldwide, among whom 30% have associated fallopian tube pathology. Fortunately, the diagnostic accuracy of tubal patency has been enhanced with the consistent development of ultrasound imaging technology, especially the invention of transvaginal 4-dimensional hysterosalpingo-contrast sonography (TV 4D HyCoSy). However, detailed imaging data for evaluating the tubal condition for spontaneous conception and assessing the necessity of assisted reproductive technology (ART) have yet to be amassed.

Methods

Patients with tubal factor infertility (TFI) who received TV 4D HyCoSy were recruited for this study. They were divided into two groups according to the method of conception: the natural pregnancy group (patients who naturally conceived within 3 months after TV 4D HyCoSy) and the assisted reproduction group (patients who failed to conceive naturally within the 3 months but successfully conceived through ART). Logistic regression analysis was performed to examine the data obtained from participants' medical history and TV 4D HyCoSy investigation.

Results

Of the initial 1,433 women, 348 were excluded due to exclusion criteria or lack of follow-up. A total of 1,085 TFI patients were finally included, with individuals in the natural pregnancy group accounting for 27.74% (n=301), and those in the ART group accounting for 37.33% (n=405). The age was younger and the duration of infertility was shorter in the group of women who conceive spontaneously after TV 4D HyCoSy (P<0.05). In terms of imaging data, their endometrial thickness was thinner, right fallopian tube wall was more intact, morphology of the right fallopian tube was smoother, and their ovarian motility (bilateral), fallopian tube visualization (bilateral) and overflow condition of the contrast agent from the fimbriae of fallopian tube (bilateral) were better. In addition, the resistance of the contrast agent injection was less likely to be persistent, reflux was less likely to happen and 0/1 dispersion of the contrast agent around the ovary (bilateral) were more likely to be annular (P<0.05).

Conclusions

The imaging data gathered from TV 4D HyCoSy in TFI patients were comprehensive, which suggested that TV 4D HyCoSy could have potential to be used to assess the necessity of post-HyCoSy ART intervention in patients with TFI. This could be of benefit in reducing the incidence of overtreatment and potential complications of ART.
