The Relationship of Breastfeeding Patterns in the Neonatal Intensive Care Unit to Maternal Symptoms of Anxiety and Depression

Association Between Pandemic-Related Maternal Perinatal Anxiety and Early Postpartum Breastfeeding Success

BACKGROUND AND OBJECTIVES

Prior studies have shown conflicting results on the impact of maternal anxiety on breastfeeding initiation and success. Furthermore, a substantial increase in maternal anxiety levels was shown in response to the COVID-19 pandemic. In this study, we aimed to investigate the relationship between maternal perinatal anxiety induced by the COVID-19 pandemic and early breastfeeding outcomes.

MATERIALS AND METHODS

This cross-sectional study was conducted in two regional maternity hospitals, involving 220 first-time pregnant patients with a gestational age of ≥37 weeks. All patients had no current diagnosis of COVID-19 and no cases of COVID-19 in their close environment at the time of admission. At 24-48 hours postpartum or at the time of discharge, three following scoring systems were employed: the Coronavirus Anxiety Scale (CAS), the State-Trait Anxiety Inventory (STAI), and the LATCH (short for latch, audible swallowing, type of nipple, comfort, and hold) score. A LATCH score of ≥8 was chosen as the cutoff point for defining successful breastfeeding performance. Spearman's rank correlation was used to evaluate relationships between the CAS, STAI scores, maternal and infant factors, and LATCH scores.

RESULTS

There were no differences in baseline characteristics between groups categorized as successful and unsuccessful in breastfeeding initiation. The mean total STAI score was 86.3±13.2, the CAS score was 1.07±1.91, and the LATCH score was 8.42±1.7. Although there was an increase in State-Trait Anxiety Inventory-State Anxiety (STAI-S) scores compared to State-Trait Anxiety Inventory-Trait Anxiety (STAI-T) scores, and the STAI-S score and CAS score were higher in the unsuccessful group, these differences did not reach statistical significance (p = 0.22 and 0.16, respectively). When we evaluated the correlation of the LATCH score with STAI total, STAI-S and STAI-T scores, CAS score, and maternal and infant factors, only the type of delivery showed a significant correlation with the LATCH score (p = 0.008).

CONCLUSIONS

Early postpartum breastfeeding efficiency, as measured by the LATCH score, was only correlated with the type of delivery. No significant correlation was found between pandemic-related maternal perinatal anxiety and early postpartum breastfeeding success.

Maternal Milk Provision in the Neonatal Intensive Care Unit and Mother–Infant Emotional Connection for Preterm Infants

Maternal milk (MM) intake during neonatal intensive care unit (NICU) hospitalization is associated with improved neurodevelopment in preterm infants. Underlying mechanisms may include stronger mother–infant emotional connection. This paper examines associations between MM provision in the NICU with maternal connection to her infant using three factors validated in our sample: maternal sensitivity, emotional concern, and positive interaction/engagement. We studied 70 mothers of infants born <1500 g and/or <32 weeks’ gestation. Associations between MM provision and mother–infant connection were modeled using median regression adjusted for clustering. Mothers who provided exclusive MM (i.e., 100% MM, no other milk) reported higher levels of maternal sensitivity by a median score of 2 units (β = 2.00, 95% CI: 0.76, 3.24, p = 0.002) than the mixed group (i.e., MM < 100% days, other milk ≥1 days), as well as greater emotional concern (β = 3.00, 95% CI: −0.002, 6.00, p = 0.05). Among mothers of very preterm infants, greater milk provision was associated with greater maternal sensitivity, but also with greater emotional concern about meeting the infant’s needs. These findings highlight the importance of supporting MM provision and early infant care as an integrated part of lactation support. The findings may also provide insight into links between MM provision in the NICU and infant neurodevelopment.

Prevalence of anxiety and post-traumatic stress (PTS) among the parents of babies admitted to neonatal units: A systematic review and meta-analysis

BACKGROUND

Parents of babies admitted to neonatal units (NNU) are exposed to a range of potentially distressing experiences, which can lead to mental health symptoms such as increased anxiety and post-traumatic stress (PTS). This review aimed to describe how anxiety and PTS are defined and assessed, and to estimate anxiety and PTS prevalence among parents of babies admitted to NNU.

METHOD

Medline, Embase, PsychoINFO, Cumulative Index to Nursing and Allied Health literature were searched to identify studies published prior to April 14, 2021. Included studies were assessed using Hoy risk of bias tool. A random-effects model was used to estimate pooled prevalence with 95% CIs. Potential sources of variation were investigated using subgroup analyses and meta-regression. The review is registered with PROSPERO (CRD42020162935).

FINDINGS

Fifty six studies involving 6,036 parents met the review criteria; 21 studies assessed anxiety, 35 assessed PTS, and 8 assessed both. The pooled prevalence of anxiety was 41.9% (95%CI:30.9, 53.0) and the pooled prevalence of PTS was 39.9% (95%CI:30.8, 48.9) among parents up to one month after the birth. Anxiety prevalence decreased to 26.3% (95%CI:10.1, 42.5) and PTS prevalence to 24.5% (95%CI:17.4, 31.6) between one month and one year after birth. More than one year after birth PTS prevalence remained high 27.1% (95%CI:20.7, 33.6). Data on anxiety at this time point were limited. There was high heterogeneity between studies and some evidence from subgroup and meta-regression analyses that study characteristics contributed to the variation in prevalence estimates.

INTERPRETATION

The prevalence of anxiety and PTS was high among parents of babies admitted to NNU. The rates declined over time, although they remained higher than population prevalence estimates for women in the perinatal period. Implementing routine screening would enable early diagnosis and effective intervention.
