The weight status of school-age children and its association with gross domestic product.

The Aim: To examine the possible relationship between the prevalence of underweight, overweight and obesity of Polish children and adolescents and the gross domestic product per capita (GDP).

Material And Methods: This report is based on the results of a nationwide, representative population study. An area of the country, the so-called Eastern Poland, where GDP per capita is less than 80% of the national average, was designated, based on the data from the Central Statistical Office of Poland (CSOP) and was compared with the rest of the country.

The relationship between selected socioeconomic factors and thinness among Polish school-aged children and adolescents.

Unlabelled: The analysis was performed on a database including 17,427 records of subjects aged 7-18 years, randomly sampled from a population of Polish students. Thinness was determined using international cut-off points, defined to pass through body mass index of 18.5 kg/m at the age of 18.

The prevalence of overweight and obesity among Polish school- aged children and adolescents.

The Aim: The aim was to estimate the prevalence of overweight and obesity among Polish school-aged children and adolescents in a population-based, random sample.

Material And Methods: A total of 17 427 children and adolescents aged 7−18 years (8 327 boys) from a nationally representative random sample were examined from 2007 to 2009 in 416 schools in all regions of Poland. Height and weight were measured and body mass index was calculated.

Preschool children blood pressure percentiles by age and height.

We aimed to construct blood pressure (BP) references for the Polish preschool children and to compare them with the United States, German and European references. BP was measured oscillometrically using a validated device in 4378 randomly selected Polish children aged 3-6 years who were free of chronic diseases and behaved quietly during BP measurement. Height and weight were also measured.

Trends in external causes of child and adolescent mortality in Poland, 1999-2012.

Objectives: To examine the pattern and trend of deaths due to external causes among Polish children and adolescents in 1999-2012, and to compare trends in Poland's neighboring countries.

Methods: Death records were obtained from the Central Statistical Office of Poland. External causes mortality rates (MR) with 95 % confidence interval were calculated.
