IntroductionBronchial asthma and atopic dermatitis (AD) are chronic diseases potentially influencing the nutritional status. AimThe aim of the study was to assess the nutritional status of children with atopic allergy symptoms including the clinical manifestation, severity and duration of the disease and the treatment. Material and methodsThe study covered 92 children aged 2 to 18 years. Atopic allergy was confirmed by positive skin tests results. The control group consisted of 124 healthy children. For both groups height, weight and thickness of the triceps, subscapular and abdominal skinfolds were performed. Based on this body mass index (BMI), Cole index and total of skinfolds were calculated. Additionally, for patients with asthma and for controls fat mass percent was estimated based on the bioelectrical impedance. ResultsIt was found that the nutritional status of children with asthma does not differ from the one observed in healthy peers. Children with atopic dermatitis aged 2 to 8 years presented worse nutritional status than the control group; however, no differences were shown between patients with AD aged 9 to 18 years and healthy children. No influence of disease severity on nutritional status of children with bronchial asthma was observed, but more advanced severity grading of AD had a negative effect on the nutritional status. No association between either disease duration or treatment and nutritional status of children with bronchial asthma was shown. Relation of treatment and nutritional status of children with AD was not observed. ConclusionChildren with AD need nutritional status monitoring.
