“…Também não foi relatada associação entre peso ao nascer e rinite alérgica ou dermatite atópica em crianças italianas de 9 anos de idade 23 , nem em uma coorte de adolescentes da Nova Zelândia 4 . Leadbitter et al 7 tampouco encontraram associação entre essas variáveis.…”

Objective: To study the association between atopy and variables such as weight, length, and socioeconomic level at birth and in young adulthood.Methods: A total of 2,063 subjects were investigated in a prospective birth cohort study of individuals born in Ribeirão Preto, Brazil, in 1978Brazil, in /1979, and examined at the age of 23-25 years. Skin prick tests (SPT) for eight common allergens in Brazil were performed. Subjects with a wheal reaction ≥ 3 mm to one or more of the eight allergens tested were considered to be atopic. We used the log-binomial model (generalized linear model) in order to assess the association between atopy and birth or adult variables. Results:The prevalence of positive SPT was 47.6%. Male gender was associated with an increased risk of atopy (relative risk [RR] = 1.18; 95% confidence interval [95%CI] 1.07-1.30). Low level of schooling was a protective factor against atopy, with a RR = 0.74; 95%CI 0.62-0.89. Living with a smoker in childhood was also associated with lower risk of atopy (RR = 0.87; 95%CI 0.79-0.96). Birth weight, length and order, maternal age, and intrauterine growth restriction were not associated with positive SPT. Conclusions:This study showed that male gender was associated with an increased risk of atopy. Low socioeconomic status, assessed by low level of schooling, was a protective factor against atopy. These data agree with the hygiene hypothesis.J Pediatr (Rio J). 2011;87(4):336-342: Allergens, allergy, risk factors, skin test. ResumoObjetivo: Estudar a associação entre atopia e variáveis como peso, comprimento e nível socioeconômico no nascimento e na idade adulta jovem. Métodos:Foram investigados 2.063 indivíduos em um estudo prospectivo de coorte de nascimento com indivíduos nascidos em Ribeirão Preto (SP), em 1978/1979, e examinados aos 23-25 anos de idade. Realizaram-se testes cutâneos de puntura (TCP) para oito alérgenos comuns no Brasil. Foram considerados atópicos os indivíduos que apresentaram reação papular ≥ 3 mm para um ou mais dos oito alérgenos testados. A fim de avaliar a associação entre atopia e variáveis no nascimento e na idade adulta, utilizamos o modelo log-binomial (modelo linear generalizado).Resultados: A prevalência de TCP positivo foi de 47,6%. O gênero masculino esteve associado a aumento do risco de atopia [risco relativo (RR) = 1,18; intervalo de confiança de 95% (IC95%) 1,07-1,30]. O baixo nível de escolaridade foi um fator de proteção contra atopia, com um RR = 0,74; IC95% 0,62-0,89. A convivência com um fumante na infân-cia também esteve associada a um menor risco de atopia (RR = 0,87; IC95% 0,79-0,96). Peso e comprimento ao nascer, ordem de nascimento, idade materna e restrição de crescimento intrauterino não estiveram associados a TPC positivo. Conclusões:Este estudo demonstrou que o gênero masculino esteve associado a um aumento do risco de atopia. O baixo nível socioeconômico, estabelecido pelo baixo nível de escolaridade, foi um fator de proteção contra a atopia. Esses dados estão de acordo com a teoria da higiene...

“…Park et al 12 reported that the incidence of nipple eczema was 6.2% in Korean atopic dermatitis patients above 12 years old. However, the incidence of nipple eczema is much lower in Western atopic dermatitis patients 13 . This may explain why no reports of CCA on the nipple area are from Western countries.…”

“…Research has shown that one of the main risk factors for the development of allergic diseases is heredity [14][15][16]. By previous survey in Vilnius, it was found, that there were 2 times more allergic children in families with allergic members in comparison with families in which no one had allergy [17].…”

Objectives: In recent decades, the prevalence of allergic diseases, including food allergy, has been increasing. This is becoming an important health problem. Many risk factors of food allergy were identified recently, and many of them still are controversial. The aim of this study was to evaluate the potential risk factors of food allergy in child population following the methodology of the EuroPrevall project. Methods: Vilnius University was a partner in the EuroPrevall integrated project "The prevalence cost and basis of food allergy in Europe", which is an EU-funded multi-disciplinary research study. A case-control study design was used to address the study question. All subjects were assessed by means of questionnaire and blood sample test for specific immunoglobulin E. Possible risk factors like mother's addictions (smoking, alcohol drinking during pregnancy), infant low birth weight and nursing duration, gender, treatment with antibiotics during first two years of life were analysed. Multiple logistic regression was used for risk factor analysis. Results: No statistically significant associations were found between risk factors and food allergy. Only gender (male) (ORa = 3.36, 95% CI 1.17 -9.63) and mother's food allergy (ORa = 5.44, 95% CI 1.19 -24.97) were directly associated with child's food allergy. Because of the presence of those both two factors (gender (male) + mother's allergy), the risk for food allergy increased particularly-OR was 18.31 (95% CI 2.01 -166.07). Conclusion: Gender (male) and mother's food allergy are the most important risk factors directly associated with children's food allergy.

The epidemiology of atopic dermatitis in Italian schoolchildren

Abstract: The prevalence of doctor-diagnosed AD in Italian schoolchildren is comparable to those reported for other developed countries. Family history of atopy was the single most important associated factor, while the complex interplay of environmental factors remains to be elucidated.
