BACKGROUND: Atopic dermatitis (AD) is one of the most common, chronic or chronically relapsing inflammatory skin diseases that affect children. Multiple genetic and environmental factors appear to regulate the pathogenesis of AD. OBJECTIVES: Our aim was to investigate the possible association between family, social, dieting, atopic and environmental factors and the severity of AD evaluated by SCORAD scores in children. MATERIALS & METHODS: The study group included 100 children with AD who attended a paediatric dermatology outpatient clinic with a median age of 18.5 months. The diagnosis of AD was established on the basis of the clinical criteria according to the American Dermatology Society, while the SCORAD score was used to evaluate disease severity. RESULTS: Multivariate linear regression analysis disclosed that excessive cleanliness (p<0.001), RAST level greater than 0.7 KU/l (p<0.001), breastfeeding for less than two months (p = 0.001), and the absence of an older sibling (p = 0.049) were statistically significant independent determinants for high SCORAD scores. Multivariate logistic regression analysis showed that excessive cleanliness (p<0.001) was the strongest independent risk factor for severe AD (SCORAD>36) (aOR: 59.4; 95% CI: 10.9-322.6). RAST level greater than 0.7 KU/l (aOR: 7.9; 95% CI: 1.5-41.0; p = 0.014) and severe passive smoking (aOR: 4.6; 95% CI: 1.0-22.1; p = 0.050) also showed a significant independent, but clearly weaker, association with severe AD. CONCLUSIONS: A short duration of breastfeeding, absence of older siblings, parental passive smoking, food allergens along with aeroallergens, and excessive cleanliness should be considered as negative prognostic factors, leading to a higher SCORAD score in children with AD.
