Egsgaard S, Bliddal M, Lund LC, Vigod SN, Munk-Olsen T. Risk and timing of postpartum depression in parents of twins compared to parents of singletons. Acta Psychiatr Scand 2025; 151:163-172. [PMID: 39455067 DOI: 10.1111/acps.13766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2024] [Revised: 09/19/2024] [Accepted: 10/12/2024] [Indexed: 10/28/2024]
Abstract
BACKGROUND Parents of twins appear to be at increased risk of postpartum depression (PPD), yet little is known about the magnitude and timing of onset in the postpartum period compared to singleton parents. METHODS We conducted a cohort study using the Danish nationwide health registers. We defined a study population of parents that is, mothers and fathers of all twin and singleton livebirths between 1997 and 2019. Postpartum depression was defined as incident depression diagnosis or a redeemed antidepressant prescription from childbirth through 365 days postpartum. We performed a parametric time-to-event analysis based on Poisson regression. The time scale was time since birth, modeled using restricted cubic splines. From this we estimated the hazard ratio (HR) representing the momentary risk, and the cumulative risk ratio (RR) over the first year postpartum, in twin compared to singleton parents. RESULTS The study population was based on 27,095 twin and 1,350,046 singleton births. In adjusted analyses, the HR of twins compared to singletons was highest around 2 months postpartum (HR 1.28, 95% CI 1.10-1.49) for mothers, and around 6 months (1.20, 95% CI 1.02-1.42) for fathers. The 6 months adjusted cumulative RR of PPD in twins compared to singletons was 1.24 (95% CI 1.10-1.40) for mothers and 1.11 (95% CI 0.95-1.30) for fathers. CONCLUSIONS Twin mothers had increased risk of PPD compared to singleton mothers, which was driven by an immediate increase after childbirth. The risk among twin fathers was not increased immediately after childbirth, but we found slightly elevated risk around 6 months postpartum. This could suggest diverse patterns of PPD symptomatology in twin parents compared to singleton parents and between mothers and fathers. Our findings underline parents of twins as a potentially vulnerable group to PPD and emphasize the need for increased awareness of their mental health.

Abstract
The attachment relationship constitutes the first emotionally significant affective bond, usually between the infant and the mother, serving as a model for subsequent relationships. It is considered a vital component of social and emotional development in the early years and an important early indicator of infant mental health. In twins, the attachment process may exhibit unique characteristics, influenced by the dual parenting dynamic and the individual needs of each baby. With this article, we intend to explore the challenges of infant-caregiver relationships and the attachment process in twins through a brief, non-systematic literature review regarding a clinical case of a 21-month-old female born from a twin pregnancy complicated by selective fetal growth restriction (sFGR), prematurity, and very low birth weight. The patient was initially suspected of displaying an insecure ambivalent/resistant attachment style, differing from her twin sister. Studies have shown a high concordance in attachment style between twin pairs, although a higher prevalence of insecure ambivalent/resistant attachment style compared to the general population. This may reflect challenges commonly presented in twin pregnancies and the perinatal period, such as sFGR, prematurity, and feeding difficulties, which increase parental stress that may impair early attachment between parents and infants. Attachment is not a fixed bond. Early identification and intervention in infant-caregiver relationship difficulties within this vulnerable group can help mitigate the challenges of dual parenting, fostering secure bonds and promoting healthy infant development.

[PMID: 38921288 PMCID: PMC11203324 DOI: 10.3390/healthcare12121173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 06/05/2024] [Accepted: 06/06/2024] [Indexed: 06/27/2024] Open
Abstract
(1) Background: The transition to twin parenthood is a demanding challenge with a higher risk of maternal and fetal complications during pregnancy and a postpartum period that involves caring for more than one newborn at the same time with similar and simultaneous needs. (2) Aim: To find out about parents' needs when experiencing the transition to twin parenthood and to describe the intervention of their specialized nursing support network. (3) Methodology: A descriptive exploratory study, based on a proper non-probabilistic sample of 15 nurses and 55 couples who are parents of twins, using two online questionnaires publicized on social networks. (4) Results: The couple's needs were identified through knowledge of their experiences and difficulties during pregnancy and after the twin birth. Couples' and nurses' perceptions differed on the identified needs. The specialized nursing support network focuses its intervention on providing informative guidance on twin pregnancy and postpartum period, health education, group sharing experiences, home visits, planning, and including a family support network in the management of twin care and the creation of a daily routine. (5) Conclusions: There is a need to implement a program focused on the needs of parents of twins, promoting realistic expectations for the birth and parenting of twins, preparing parents, improving their well-being, and creating a specialized nursing support network available to this population.

JMIR Hum Factors 2024; 11:e50098. [PMID: 38753421 PMCID: PMC11140274 DOI: 10.2196/50098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 10/05/2023] [Accepted: 03/01/2024] [Indexed: 05/18/2024] Open
Abstract
BACKGROUND Digital interventions are gaining increasing interest due to their structured nature, ready availability, and self-administered capabilities. Perinatal women have expressed a desire for such interventions. In this regard, behavioral activation interventions may be particularly suitable for digital administration. OBJECTIVE This study aims to exploratorily investigate and compare the feasibility of the internet-based self-help guided versus unguided version of the Brief Behavioral Activation Treatment for Depression-Revised, an empirically supported in-person behavioral activation protocol, targeting pregnant women with subclinical depression symptoms. A user-centered design is used, whereby data are collected with the intent of evaluating how to adjust the intervention in line with pregnant women's needs. Usability and user engagement were evaluated. METHODS A total of 11 Italian pregnant women with subclinical depressive symptoms based on the Patient Health Questionnaire-9 (scoring<15) participated in this study; of them, 6 (55%) women were randomly assigned to the guided group (age: mean 32.17, SD 4.36 years) and 5 (45%) to the unguided group (age: mean 31, SD 4.95 years). The Moodle platform was used to deliver the interventions in an e-learning format. It consisted of 6 core modules and 3 optional modules; the latter aimed at revising the content of the former. In the guided group, each woman had weekly chats with their assigned human guide to support them in the homework revisions. The intervention content included text, pictures, and videos. Semistructured interviews were conducted, and descriptive statistics were analyzed. RESULTS Collectively, the data suggest that the guided intervention was better accepted than the unguided one. However, the high rates of dropout (at T6: guided group: 3/6, 50%; unguided: 4/5, 80%) suggest that a digital replica of Behavioral Activation Treatment for Depression-Revised may not be feasible in an e-learning format. The reduced usability of the platform used was reported, and homework was perceived as too time-consuming and effort-intensive. Moreover, the 6 core modules were deemed sufficient for the intervention's goals, suggesting that the 3 optional modules could be eliminated. Nevertheless, participants from both groups expressed satisfaction with the content and found it relevant to their pregnancy experiences. CONCLUSIONS Overall, the findings have emphasized both the intervention's merits and shortcomings. Results highlight the unsuitability of replicating an in-person protocol digitally as well as of the use of nonprofessional tools for the implementation of self-help interventions, ultimately making the intervention not feasible. Pregnant women have nonetheless expressed a desire to receive psychological support and commented on the possibilities of digital psychosocial supports, particularly those that are app-based. The information collected and the issues identified here are important to guide the development and co-design of a more refined platform for the intervention deployment and to tailor the intervention's content to pregnant women's needs.

Abstract
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.

Abstract
BACKGROUND While twin pregnancy (TP) is associated with increased maternal physical and psychological risks, little is known about how this context interferes with prenatal attachment. AIMS To compare the level of prenatal attachment between women with TP and singleton pregnancy (SP), and to investigate socio-demographic, maternal mental health and pregnancy-related predictors. STUDY DESIGN Case-control study in a university hospital. SUBJECTS 119 women with TP during their last trimester of pregnancy versus 103 women with SP. OUTCOME MEASURES The Prenatal Attachment Inventory (PAI), the Edinburgh Postnatal Depression Scale (EPDS), in addition to the collection of general socio-demographic and medical data. RESULTS The mean PAI total score did not significantly differ between the two groups. In the group of women with TP, low but statistically significant correlations were found between the PAI total score and the EPDS total score (r = -0.21) and with maternal age (r = -0.20). CONCLUSIONS No major difference in prenatal attachment was found in women TP compared to those with SP. A higher level of depressive symptoms is worth considering to explore the risk of suboptimal attachment in this population. Questions were raised about the applicability of usual measures of prenatal attachment in this context.

Ecological momentary assessment of postpartum outcomes in mothers of multiples: lower maternal-infant bonding, higher stress, and more disrupted sleep. Arch Womens Ment Health 2023; 26:361-378.

Abstract
Research on mental health in mothers of multiples has neglected important outcomes like postpartum bonding and relationship satisfaction and is limited by reliance on single-administration, retrospective measures. This study fills these gaps by assessing previously unexamined variables and using ecological momentary assessment (EMA), wherein participants answer repeated, brief surveys to measure real-world, real-time outcomes. This online study recruited 221 women and compared outcomes in those who birthed multiples (n = 127, 57.47%) vs. singletons (n = 94, 42.53%). When recruited, participants were either 6-12 (n = 129, 58.37%) or 18-24 (n = 83, 37.56%) weeks postpartum. All 221 participants completed baseline measures of self-reported depression, anxiety, stress, sleep, relationship satisfaction, and maternal-infant bonding. One hundred thirty participants (58.82%) engaged in 7 days of EMA assessing self-reported momentary mood, stress, fatigue, bonding, and sleep. Data were analyzed using two-by-two ANOVAs and hierarchical linear modeling. Mothers of multiples reported more baseline parenting stress and less maternal-infant bonding than mothers of singletons (ps < .05). Mothers of multiples who were 6-12 weeks postpartum reported the lowest bonding (p = .03). Mothers of multiples also reported more momentary stress, overwhelm, nighttime awakenings, and wake time after sleep onset (ps < .05). The latter two variables positively correlated with momentary fatigue, stress, and worse mood (ps < .05). Mothers of multiples experienced worse postpartum bonding, more stress, and more interrupted sleep than mothers of singletons. This population may benefit from tailored postpartum interventions to decrease stress, increase bonding, and improve sleep.

Abstract
Twin pregnancy is a risk factor for postpartum depression and anxiety. Whether this translates into a higher risk of severe maternal mental illness in the short-term or long-term is unknown. This study was a population-based retrospective cohort study, using linked health administrative databases for the entire province of Ontario, Canada. Included were primiparas aged 15-50 years with a twin vs. singleton hospital livebirth, between January 1, 2003, and March 31, 2019. Propensity-score inverse probability of treatment weights accounted for potential confounding. The primary outcome of severe mental illness comprised a composite of an emergency department visit or hospitalization for mental illness or self-injury, or death by suicide, assessed in the first year after birth, and in long-term follow-up, up to 17 years thereafter. Fifteen thousand twenty-four twin and 796,804 (15,022 weighted) singleton births were included, with a mean (IQR) duration of follow-up of 9 (5-13) years. After weighting, the mean (SD) maternal age was 31.3 (5.5) years. In the first 365 days postpartum, severe mental illness occurred at rates of 10.5 and 8.7 per 1000 person-years in twin and singleton mothers, respectively, corresponding to a hazard ratio (HR) of 1.21 (95% CI 1.07-1.47). From 366 days onward, the corresponding figures were 5.9 and 6.1 per 1000 person-years (HR 0.96, 95% CI 0.89-1.04). Individuals with a twin birth appear to experience an increased risk for severe mental illness in the first year postpartum, but not thereafter. This suggests a potential need for targeted counselling and mental health services for mothers within the first year after birth.

Abstract
Quadruplets are at elevated physical risks at prenatal, perinatal, and postnatal levels, relative to twins. A brief review of this area is followed by discussion of a female quadruplet with three co-quadruplet brothers. Next, several timely twin research reports are examined. The topics include antenatal corticosteroids and twins' neonatal outcomes, the meaning of fatherhood in families with twins, what doppelgängers (look-alikes) reveal about physical and behavioral similarity, and monozygotic (MZ) co-twin discordance for asymmetric pigmented paravenous chorioretinal atrophy. A lawsuit involving alleged cheating on a medical school examination by identical twins is also reviewed. General interest stories cover opposite-sex twin Holocaust survivors, twin models at a Gucci fashion show, twins with different fathers, reunited female twins who entered the same convent, the death of an MZ female twin soldier during training, and the surgical separation of conjoined twins in Brazil.
