Quality of attachment in infants less than 1500g or less than 32weeks. Related factors.

Background: Prematurity carries a high risk of mortality and sequelae, altering the bonding process and leading to repercussions in terms of attachment.

Objective: To assess the type of attachment in children under 32weeks' gestational age (GA) or below 1500g, in hospitals where development-centred care has been implemented and to study the association between various types of attachment and certain neonatal and family characteristics.

Method: Children <1500g or <32weeks GA who were born or admitted before 48h of life to one of two hospitals in Madrid between January and December 2012 were candidates for the study.
