چکیده

BACKGROUND The prevalence of atopic dermatitis (AD), a chronic skin disease, has increased substantially in recent decades, and different factors have been implicated in its etiology. Although dietary habits are being investigated, few conclusive findings have been reported. Nevertheless, increased consumption of polyunsaturated fatty acids (PUFA) and a diet poor in antioxidants have been related to AD. OBJECTIVES The objectives of this study were to investigate the association between AD, the intake of different foods, and the effect of a Mediterranean diet among Spanish schoolchildren aged 6 to 7. METHODS We performed a cross-sectional study with 20 106 schoolchildren aged 6-7 years from 10 different areas of Spain. The participation rate was 76.50%. The prevalence of AD was assessed using the International Study of Asthma and Allergies in Childhood questionnaire and the criteria of the Spanish Academy of Dermatology. To calculate the Mediterranean diet score, we classified food into 2 groups: Mediterranean food, including fruit, seafood, vegetables, pulses, cereals, pasta, rice, and potatoes; and non-Mediterranean food, including meat, milk, and fast food. RESULTS Milk was negatively associated with AD. Butter and nuts also were negatively associated, although statistical significance was only reached when these foods were consumed 3 or more times a week. CONCLUSIONS We found no association between the Mediterranean diet score and AD and a positive association between AD and obesity.
