The Short Stature in Atopic Dermatitis Patients: Are Atopic Children Really Small for Their Age?

BACKGROUND Short stature is sometimes seen in children with atopic dermatitis (AD); however, the topic has never been studied systematically. OBJECTIVE The aim of this study was to show whether AD itself affects stature in children and to evaluate the influence of other relevant factors such as genetic background, diet restrictions, and sleep disturbance on the stature of children with AD. OBJECTIVE The aim of this study was to show whether AD itself affects stature in children and to evaluate the influence of other relevant factors such as genetic background, diet restrictions, and sleep disturbance on the stature of children with AD. METHODS The study population included Korean children 7 to 8 years of age who live in one district of Seoul, Korea. We used a questionnaire as an investigating tool to survey genetic backgrounds, environmental factors, and comorbidities. Student's t-test and linear regression were employed for statistical analysis. RESULTS In univariate analysis, the average stature in the AD group was short compared with the normal control group. Parental stature, dietary habit, and sleep patterns were also relevant factors with respect to stature. However, in multivariate analysis, AD itself had no influence on stature. Significant correlations were found for such factors as parental height, sleep disturbance, presence of asthma, and dietary restrictions, in decreasing magnitude. CONCLUSION These results suggest that AD itself may not be the causative factor for short stature in children with AD. Therefore, consideration of other relevant factors related to short stature in patients with AD will be important for the proper management of the disease.
