Abstract

Background Prevalence of atopy, allergic diseases, and obesity are increasing. Atopy is an individu and/or familial tendency to sensitization in response to ordinary exposure to allergens. Studies on association of BM I with atopy and allergic diseases in children were limited, with inconclusive results. Objective To assess associations of BM I with atopy and allergic diseases in chidren. Methods A cross-sectional was conducted in school children aged 6-12 years in Lhokseumawe City, Aceh, June 2012. Children were assessed for BMI, skin prick test, and International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Statistical analyses included Chi-square, Fisher exact, and logistic regression. Results The subjects consisted of 137 (85.6%) normoweight, 12 (7.5%) overweight, and 11 (6.9%) obesity. Skin prick test results were positive in 44 (27.5%) and negative in 116 (72.5%) subjects. Allergic manifestations were allergic rhinitis (AR) 17 (10.6%), bronchial asthma 6 (3.8%), and atopic dermatitis (AD) 3 (1.9%). There was significant association of obesity with atopy, compared with normoweight (OR=3.78; 95%CI 1.08 to 13.19; P=0.037), but no significant association found when family history of atopy also assesed. There was significant association of obesity with bronchial asthma (OR=9.92; 95%CI 1.46 to 67.18; P=0.004) and AR (OR=6.49; 95%CI 1.64 to 25.66; P=0.015), compared with normoweight children. Significant association of overweight with atopy and allergic disease were not found. Conclusion Obese children are more likely to have atopy, bronchial asthma, and allergic rhinitis, but overweight and normoweight children are not.

Abstract

Background The prevalence of asthma in children has increased in many countries. Environmental factors are believed to play an important role and an inverse relationship between number of siblings and atopic disorders has been observed.Objective To assess for an association between bronchial asthma in atopic children and their number of siblings.Methods A cross-secrional study was conducted from June to November 2010 in three elementary schools in Medan, North Sumatera. Trace cards from the Allergy-Immunology Indonesian Pediatric Association (IDAI) Working Group and questionnaires on the clinical history of atopy were used to screen children with the risk of atopy. The International Study of .Asthma and Allergies in Childhood (ISAAC) questionnaire to screen for bronchial asthma was distributed to children aged 7-10 years with a history of asthma, allergic rhinitis or atopic dermatitis. Subjects were divided into two groups, those with <3 siblings and those with 2:3 siblings. Chi-square test was used to analyze differences in bronchial asthma prevalence between the two groups.Results Ninety-six subjects enrolled in the study, with 48 subjects per group. The prevalence of bronchial asthma was significantly higher in atopic children who had <3 siblings than in children with 2:3 siblings (73.5% and 26.5%, respectively; P=0.04).Conclusion Bronchial asthma was significantly more frequent in children with less than 3 siblings compared to those with 3 or more siblings.
