Underweight, overweight and obesity among children and adolescents is an important epidemiological problem, mostly because of consequences of health perturbations. This paper is intended to present the analysis of characteristics of children and adolescent physical growth in the context of social and economical situation of families inhabiting the city of Bytom. The Box-Cox transformation according to WHO standards for body weight, body height and BMI (Body Mass Index) is applied in the analysis. The transformation is a base for statistical analysis of measurable data using e.g. t-test, or Mann-Whitney test. Frequencies of underweight, overweight and obesity among children and adolescents are determined by centile ranks and growth charts by the Institute of Mother and Child in Warsaw, Poland, and analysed using differences significance test and the post-hoc test by Benferroni for percentages. The influence of social and economical factors are evaluated with #2-test and log-linear analysis. The main conclusion of the analysis confirms that the percentage of children and adolescents with overweight or obesity is growing. Moreover, the influence of social and economical factors (e.g. education of parents, or the average income per person) is significant. These are premises for further investigations and research in this field.

Objectives This study explores the association between self-reported exposure to traffic-related air pollution and respiratory health symptoms, as well as lung functions and skin prick tests in adolescents living in the vicinity of main roads. Material and Methods The data in the study were acquired using a cross-sectional study conducted between 2004–2005 in Chorzów (Silesia, Poland) among adolescents (N = 936) aged 13–15 years, attending junior high schools. Adverse respiratory health symptoms and exposure to traffic-related air pollution were determined on the basis of a questionnaire. Moreover, all children underwent spirometry and skin prick tests. Multivariable logistic regression with multiple imputation for missing data was used to assess the prevalence of adverse respiratory symptoms in relation to self-reported exposure to traffic-related air pollution, adjusted for socioeconomic and environmental factors. Results Among respiratory tract diseases, asthma and allergic rhinitis associations were statistically significant (OR = 2.16, 95% CI: 1.12–4.15 and OR = 1.69, 95% CI: 1.08–2.64, respectively). Likewise, among respiratory disorders, statistically significant associations were found in the case of wheezes and dyspnea attack (OR = 1.58, 95% CI: 1.10–2.26 and OR = 2.39, 95% CI: 1.56–3.66, respectively), with respect to the vicinity of the main road. Living in the area with high traffic intensity was statistically significantly associated with a higher prevalence of asthma and wheezes (OR = 2.31, 95% CI: 1.22–4.39 and 1.48, 95% CI: 1.09–2.01, respectively). The results obtained did not confirm the relationship between the adopted way of exposure to traffic-related air pollution and lung function indices or skin prick tests. Conclusions Results of the study suggest that children living in the area with intense traffic are more likely to develop respiratory disorders. Moreover, the vicinity of a main road as well as traffic intensity could be suitable in assessing the relationship between road transport and potential health problems among exposed inhabitants.
