Evaluation of Anxiety Levels and Related Factors in Parents of Preterm Infants Hospitalized in NICU

Abstract

Background: The hospitalization of preterm infants in Neonatal Intensive Care Unit (NICU) is generally an unexpected event that can be stressful experience for families and especially for parents. Objective: To assess the anxiety levels in parents with preterm infants hospitalized in NICU and determine its association with clinical and sociodemographic variables. Method: This prospective, follow up–cohort study was conducted at the NICU of a tertiary maternity hospital in Athens, Greece during 18/12/2019 to 31/12/2022. A total of 120 parents, whose infants had birth weight (BW)<1750 grams (g) and gestational age (GA)<34 weeks (w) were involved. The data collected by a demographic form and the State-Trait Anxiety Inventory Scale (STAI). Results: Our data showed that the STAI score for state anxiety to mothers was significantly higher in the 1st assessment (Mean±SD:52.2±11.9) than 2nd (Mean±SD:47.8±12) and 3rd (Mean±SD:49±10.3). The STAI score for trait anxiety was similar, in particular it was significantly higher in the 1st assessment (Mean±SD:46.6±14.6) compared to 2nd (Mean±SD:41.9±14) and 3rd (Mean±SD:42.8±13). Also, the STAI score for state anxiety to fathers was significantly higher during the 1st assessment (Mean±SD:47.1±12.2) compared to the other two assessments (Mean±SD:42.8±9.8 & Mean±SD:41.7±9.1 respectively), while trait anxiety didn’t show significant variability. Conclusion: Our findings suggested that the premature birth and infant’s hospitalization might have a negative effect on parents’ emotional state. Identifying which mothers and fathers are at risk immediately after birth and during NICU stay could help to direct specific interventions that can prevent them of stressful feelings.
