Information regarding eczema was collected at ages 1, 2, 4, 10 and 18 years from the 1989 Isle of Wight birth cohort (n=1456). Skin prick testing was performed at 4, 10 and 18 years of age.
The prevalence of eczema from birth to 18 years of age remained relatively constant (12-14%) with minimal remission.
Up to 10 years of age, gender did not influence prevalence. From 10 to 18 years, eczema became more prevalent among girls (16% for girls vs. 8% for boys).
There was only a minimal reduction in the prevalence of eczema during childhood and adolescence. During adolescence, more girls develop eczema and more boys outgrow it.
