Factors Influencing Paternal Attachment Among Preterm Infants in an Urban Neonatal Intensive Care Unit

The aim of this study is to elucidate factors that may influence paternal attachment to preterm infants in an urban hospital setting. Fathers of preterm infants admitted to a level III neonatal intensive care unit (NICU) were eligible for this study. The Paternal Postnatal Attachment Scale (PPAS) is a questionnaire that invokes paternal attachment in five domains: patience, tolerance, pleasure, affection and pride. Clinical and demographic data were collected along with the PPAS to identify factors influencing paternal attachment. Infants studied were 28.1 ± 3.3 weeks gestational age with a birth weight of 1,070 ± 70 grams. Paternal age was 29.2 ± 6.6 years. Infants of fathers who scored in the lowest quartile of attachment were significantly smaller (756 ± 17 grams vs 1,210 ± 76 grams, p = 0.03) and more immature (26.4 ± 1.9 weeks vs 28.8 ± 3.5 weeks, p = 0.04) than infants of fathers with higher attachment scores. Subscores of patience and tolerance (p = 0.05) and pleasure in interaction (p = 0.01) were also significantly lower although there was no significant difference in subscores of affection and pride (p = 0.36). There were no significant differences between attachment scores for paternal age, educational level, marital status, number of children or breastfeeding status. Paternal attachment scores appear to be dependent on infant factors, such as birth weight and gestational age, rather than paternal or demographic factors.
