Insights
Paternal anxiety did not impact maternal bonding in preterm infants. However, paternal anxiety levels varied by country, and maternal depression predicted paternal anxiety, suggesting a need for further research on parental mental health.
Area of Science:
- Neonatal Intensive Care Unit (NICU) care
- Parental mental health
- Maternal-infant bonding
Background:
- NICU hospitalization of preterm infants can negatively impact parental mental health.
- Limited understanding exists regarding the influence of paternal anxiety on the maternal-infant relationship.
Purpose of the Study:
- To investigate the association between paternal anxiety and maternal bonding in the NICU setting.
- To explore factors influencing paternal anxiety, including geographical site, maternal depression, and infant characteristics.
Main Methods:
- Secondary analysis of the multinational LongSTEP randomized controlled trial dataset.
- Prospective cohort study utilizing linear mixed-effects models.
- Assessment of paternal anxiety (GAD-7) and maternal bonding (PBQ) at NICU discharge, and at 6 and 12 months corrected infant age.
Main Results:
- Paternal anxiety did not significantly predict maternal bonding at any time point (discharge, 6 months, 12 months).
- Significant variations in paternal anxiety were observed across study sites, particularly higher levels in Colombian sites.
- Maternal depression was a significant predictor of paternal anxiety at baseline and NICU discharge.
Conclusions:
- Paternal anxiety does not appear to directly influence maternal bonding with preterm infants.
- Cultural factors may play a role in the manifestation of paternal anxiety, necessitating further investigation.
- The correlation between maternal depression and paternal anxiety highlights the interconnectedness of parental mental health in the NICU context.
Background:
The hospitalization of a preterm infant in the NICU can lead to mental health difficulties in parents, but not much is known how paternal anxiety might affect the mother-infant relationship.
Methods:
This prospective cohort study is a secondary analysis investigating how paternal anxiety levels might affect maternal bonding in the NICU using the dataset of the multinational pragmatic randomized controlled trial LongSTEP. A linear mixed-effects model was used for correlations of paternal anxiety (GAD-7) and maternal bonding (PBQ) at NICU discharge, and at 6 and 12 months infant corrected age. Secondary analyses examined effects on paternal anxiety related to: site (Argentina, Colombia, Israel, Norway, and Poland), maternal depression (EPDS), infant gestational age at birth, paternal age, and type of pregnancy.
Results:
Paternal anxiety did not predict maternal bonding at NICU discharge (p = 0.096), at 6 months (p = 0.316), or at 12 months infant corrected age (p = 0.473). Secondary outcomes showed a statistically significant site effect, with higher paternal anxiety levels at the two Colombian sites at baseline (p = 0.014 and p = 0.020) and for one site at discharge (p = 0.012), but not for paternal age (p = 0.925 and p = 0.793), infant gestational age at birth (p = 0.974 and p = 0.686 and p = 0.340), or type of pregnancy (p = 0.381). Maternal depression predicted paternal anxiety at baseline (p < 0.001) and at discharge (p = 0.003).
Conclusions:
In this study, paternal anxiety did not predict maternal bonding. Paternal anxiety varied by site, indicating a need for research on potential cultural differences in manifestation of paternal anxiety. Maternal depression predicted paternal anxiety, confirming a previously reported correlation. Further research on variations in paternal mental health in the neonatal period is warranted, as well as exploration of the social contagion of mental health in preterm parents.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
