Associations of eczema phenotypes with emotional and behavioural problems from birth until school age. The Generation...

Area of Science:

• Pediatric Dermatology
• Developmental Psychology
• Child Psychiatry

Background:

• Eczema (atopic dermatitis) and emotional/behavioral problems are common in children.
• The precise relationship between childhood eczema and psychological outcomes remains unclear.

Purpose of the Study:

• To investigate associations between eczema phenotypes and emotional/behavioral problems in school-aged children.
• To analyze bidirectional relationships between eczema and emotional/behavioral problems from birth to age 10.

Main Methods:

• Prospective, population-based cohort study of 5265 individuals.
• Eczema phenotypes identified based on parent-report and physician diagnosis (6 months to 10 years).
• Emotional (internalizing) and behavioral (externalizing) problems assessed using Child Behavior Checklist (1.5 to 10 years); cross-lagged models used.

Main Results:

• All eczema phenotypes correlated with increased internalizing and attention problems at age 10.
• Early transient eczema linked to more aggressive behavior symptoms at age 10.
• Eczema at 0-2 years predicted later internalizing/externalizing problems; internalizing problems predicted later eczema.

Conclusions:

• Eczema phenotypes show modest associations with attention problems and somatic symptoms in school-aged children.
• Early transient eczema is associated with increased aggressive behavior.
• Evidence suggests a directional effect from early childhood eczema to later emotional and behavioral problems.
