The frequency of common skin conditions in preschool-age children in Australia: atopic dermatitis.
OBJECTIVE
To determine the prevalence and severity of atopic dermatitis in a stratified cross-section of preschool-age children examined throughout Victoria, Australia.


METHODS
A cross-sectional skin survey using a selected cluster sample of the various centers throughout Victoria.


METHODS
The study population included Victorian children attending child-care centers, preschools, and Maternal and Child Health Centres, with the reference population being Australian children aged 5 years and younger.


METHODS
Of 1634 potential participants, 1116 children (68.3%) were examined.


METHODS
A dermatologist performed a total skin examination, including head and neck, limbs, and trunk, on all children. The diaper area was examined in children younger than 12 months.


METHODS
All parents were administered a questionnaire to elicit demographic information, history of skin conditions, and family history of skin problems or related diseases. The examiner recorded the presence, site, and severity of atopic dermatitis for calculation of age- and sex-specific prevalence rates.


RESULTS
The age- and sex-adjusted point prevalence was 30.8% (95% confidence interval [CI], 28.0%-33.5%). Most children (63.7%) were classified as having minimal or mild disease. Only 5.8% of children with atopic dermatitis did not have face or flexural involvement. Of the 237 children with atopic dermatitis and information available, 209 used 1 or more products to treat their condition.


CONCLUSIONS
Atopic dermatitis is common, decreasing in prevalence after the first 3 years of life. Most children have mild disease requiring little if any treatment, and much could be prevented with simple measures. Educational programs directed at those caring for preschool-age children that provide information on simple preventive measures, where practical, and sources of advice for treatment, if necessary, could substantially reduce the morbidity of this condition in predisposed children.
