Prevalence and associated factors for asthma in Brazilian and Japanese schoolchildren living in the city of Sao Paulo, Brazil

Objectives. Ethnic background interferes on the prevalence of asthma among schoolchildren (4 to 9 years old, SC) born and living in Sao Paulo, Brazil. Methods. International Study of Asthma and Allergy in Childhood (ISAAC)'s written standard and complementary questionnaires were applied to SC (similar socioeconomic status) living in the city of Sao Paulo: no-Japanese Brazilian (NJB, N = 306) and Japanese Brazilian (third generation, born in Brazil, from Japanese families with no miscegenation, JB, N = 258). Results. The prevalence of current asthma was significantly higher among NJB in comparison to JB (22.2% vs 14.7%, respectively). To have rhinitis and to exercise less than once/week were risk factors for both groups of children. Conclusion. Although both groups were apparently exposed to the same environment, other cultural differences do not allow us to conclude about the ethnic component having greater influence than the environment in the development of asthma in these individuals.Univ Santo Amaro, Sao Paulo, BrazilFed Univ Sao Paulo EPM UNIFESP, Escola Paulista Med, Dept Pediat, Div Allergy Clin Immunol & Rheumatol, Sao Paulo, BrazilABCs Fac Med, Dept Pediat, Sao Paulo, BrazilEPM UNIFESP, Div Allergy Clin Immunol & Rheumatol, Dept Pediat, Sao Paulo, BrazilUniv Nove Julho UNINOVE, Sao Paulo, BrazilFed Univ Sao Paulo EPM UNIFESP, Escola Paulista Med, Dept Pediat, Div Allergy Clin Immunol & Rheumatol, Sao Paulo, BrazilEPM UNIFESP, Div Allergy Clin Immunol & Rheumatol, Dept Pediat, Sao Paulo, BrazilWeb of Scienc

Prevalence of atopic eczema and related symptoms in Brazilian schoolchildren: Results from the International Study of Asthma and Allergies in Childhood (ISAAC) phase 3

Background: International comparisons of the prevalence of atopic eczema and related Symptoms are scarce. The standardized protocol of the International Study of Asthma and Allergies in Childhood (ISAAC) facilitates investigation of prevalence all over the world.Objective: To apply the ISAAC written questionnaire to evaluate the prevalence of atopic eczema and related symptoms among 6-7 year-old children and 13-14 year-old adolescents living in 20 Brazilian cities.Methods: The ISAAC written questionnaire was filled in by 23422 children aged 6-7 years and 58 144 adolescents aged 13-14 years living in 2 population centers in the north, 8 in the northeast, 1 in the midwest, 5 in the southeast, and 5 in the south.Results: The prevalence of flexural eczema (itchy rash ever in characteristic places in the last 12 months) ranged from 5.3% to 13.0% for children and was lower among the adolescents (range, 3.4%-7.9%). Among children, the highest rates were observed in population centers in the northeast, mainly along the coast. Among adolescents the highest rates were observed in the north and northeast, mainly in Natal, Aracaju, and Vitoria da Conquista. The northeastern countryside had higher prevalence rates of severe eczema (kept awake at night by this itchy rash in the last 12 months) in comparison to northeastern coastal centers. There was a significant correlation between the prevalence of flexural eczema and severe eczema for both age groups, separately (6-7 year-olds, p=0.756, P <.004; 13-14 year-olds, p=0.874, P <.0001) or grouped (6-7 plus 13-14 years-olds, p =0.696, P <.0001).Conclusion: The prevalence of eczema and related symptoms is variable in Brazil, where the highest prevalence is found in the north and northeast; on the other hand, a higher prevalence of severe eczema was observed in Brazilian centers in the south.Univ Fed Sao Paulo, Dept Pediat, Div Rheumatol Allergy & Clin Immunol, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Pediat, Div Rheumatol Allergy & Clin Immunol, Sao Paulo, BrazilWeb of Scienc
