Introduction: Global epidemiological studies have revealed considerable geographical differences in prevalence of atopic dermatitis (AD). Aim: To present the epidemiology of AD, risk factors and co-occurrence of allergic diseases in the Polish population. Material and methods: The present paper is a part of the Epidemiology of Allergic Disorders in Poland study. We studied 22 703 participants by ECRHS/ISAAC questionnaire; 18 617 (53.8% female, 24.2% 6-7 y.o., 25.4% 13-14 y.o., 50.4% 20-44 y.o.) completed questionnaires were accepted. Four thousand seven hundred and eighty-three participants (25.7%) have undergone a medical examination. Results: Atopic dermatitis was diagnosed in 3.91% (6-7 y.o. 5.34%, 13-14 y.o. 4.3%, adults 3.02%), more often in females (OR = 1.52; 95% CI: 0.56-0.77), in the cities (OR = 2.23; 95% CI: 1.61-3.09), in mothers (OR = 2.07; 95% CI: 1.72-2.48) and fathers (OR = 2.00; 95% CI: 1.61-2.49) with atopy, higher education (OR = 1.61; 95% CI: 1.11-2.32) and economic status (OR = 1.35; 95% CI: 1.04-1.74). The highest prevalence was found in Katowice (4.89%) and lowest in rural areas (1.9%). Coexisting AD and allergic rhinitis (AR) was found in 26.17%, AR and asthma in 9.09% and AD, AR and asthma in 14.6%. Atopic dermatitis was diagnosed by allergologists in 6.5% (6-7 y.o. 8.7%, 13-14 y.o. 9.0%, adults 3.6%). Most diagnoses were made in Poznan (16.76%) and smallest in rural area (3.67%). 78.8% of subjects were diagnosed with AD for the first time although they had earlier experienced its symptoms. Conclusions: Atopic dermatitis prevalence in Poland is below the mean rate for Europe, but the risk factor profile is similar to other countries. Atopic dermatitis is more frequent in well-educated females with atopic parents and high socioeconomic status and who live in a city. [ABSTRACT FROM AUTHOR]

Introduction: Studies based on the ISAAC questionnaire suggest a correlation between the use of antibiotics and the prevalence of asthma and allergy in children aged 6-7 years. The number of courses of antibiotic therapy is an important factor. Objectives: To investigate the relationship between the use of antibiotics during the first years of life and the prevalence of allergy and asthma among children (aged 6-8 years) in the urban population of Poland. Materials and Methods: A survey-based study with a self-completed questionnaire. The respondents were parents of children aged 6-8 years living in Warszawa, Poland. 1461 completed questionnaires were collected. Results: Asthma was declared in 4.3% of the children. Wheezing and/or sibilant rhonchi within 12 months before the study was observed in 13.5% of the cases. Asthma medication was taken by 21.8% of the children. Allergic rhinitis was declared in 18.7% of the children. Problems with sneezing, rhinorrhea, and nasal congestion not associated with cold or fever were observed in 40.7% of the children. The analysis of the odds ratios between the use of antibiotics and the symptoms of allergic diseases revealed a clear correlation. The highest odds ratio was observed between the completion of over three courses of antibiotic therapy prior to the age of 12 months and the declaration of one of the following: asthma (OR = 5.59, 95% CI: 2.6-12.01), wheezing and/or sibilant rhonchi (OR = 4.68, 95% CI: 3.01-7.27) and taking medicines for breathlessness (OR = 5.12, 95% CI: 3.42-7.68). Conclusions: There is a direct relationship between antibiotic use in the first 3 years of life and asthma and allergy symptoms in children aged 6-8 years old. [ABSTRACT FROM AUTHOR]
