Sammenhengen mellom kolikk og søvnproblemer blant spedbarn og utviklings-, emosjonelle- og atferdsproblemer: en longitudinell studie

Søvnproblemer og kolikk hos spedbarn har vært knyttet til negativ helse, men det er begrenset kunnskap om sammenhengen mellom søvn- og kolikkproblemer i spedbarnsalderen og påfølgende utviklings-, emosjonelle- og atferdsproblemer hos små barn. Forskere fra Oslo MET universitet, Akershus universitetssykehus og Universitetet i Oslo har i denne studien undersøkt sammenhengen mellom spedbarnsgråt og søvnproblemer ved 6 måneders alder og atferds- og utviklingsproblemer ved 18 måneder, 3 og 5 års alder. Data fra 86724 barn hentet fra den norske mor-, far- og barn-undersøkelsen (MoBa), ble inkludert i studien. Forskerne konkluderer med at kolikk- og søvnproblemer tidlig i livet bør vurderes som risikofaktorer for utviklings- og atferdsproblemer i løpet av de første 5 årene av et barns liv.

Background: Sleep and colic problems in infancy have been linked to adverse health outcome, but there is limited knowledge of the association between sleep and colic problems in infancy and subsequent development, emotional and behavior problems in young children. The aim of the present study was to examine whether there is an associations between infants' crying and sleep problems at 6 months and behavioral and development problems at 18 months, 3 and 5 years.
Methods: This study is based on the Norwegian Mother, Father and Child Cohort Study (MoBa), conducted at the Norwegian Institute of Public Health from June 1999 to December 2008. A total of 86,724 children were included. Colic and sleep (sleep duration, nocturnal awakenings and easy to put to bed) was assessed by mother-reports. Z-scores were used to assess differences between groups of children (e.g. having colic or not, having a sleep problem or not). Emotional and behavioral problems were measured with items from the Child Behavior Checklist. Development problems were measured with items from The Ages and Stages Questionnaire.
Results: Infants with colic scored significantly lower on development at 5 years (B=-0.10, CI [- 0.14 to - 0.06]) and higher on internalizing problems both at 3 years (B=0.15. CI [0.11 to 0.18]) and 5 years (B=0.17. CI [0.12 to 0.21]) than the reference population. Children who awoke frequently and were more difficult to put to bed at 6 months scored significantly lower on development at 18 months and 3 and 5 years, and higher on internalizing behavior problems at 3 and 5 years (B=0.18 and B=0.16). Children with shorter sleep duration at 6 months had more internalizing behavior problems at 3 years (B=0.14. CI [0.07 to 0.21]) and 5 years (B=0.15. CI [0.05 to 0.25]) than the reference population.
Conclusions: Colic and sleep problems early in life should be taken into account as risk factors for development and behavioral problems within the first 5 years of a child's life.
