Increasing disproportions in the economic status of the Polish population are tangibly reflected in differences in the nutritional status of children and adolescents.
The objective of this study was to determine changes in the population size of girls with proper BMI values and their peers with underweight, overweight and obesity in a twenty-year time span.
The survey conducted in 1986 covered 17 586 girls, whereas that conducted twenty years later covered 9540 girls. Measurements were taken of body height and body mass of the girls, which enabled calculating values of their Body Mass Index (BMI). Pursuant to guidelines of the International Obesity Task Force, girls with the 3rd degree underweight (gr. I), with the 2nd degree underweight (gr. II), with the 1st degree under-weight (gr. III), with proper BMI values (gr. IV), with overweight (gr. V), and with obesity (gr. VI) were selected from the biological material. The statistical significance of differences between mean values achieved in the year 1986 and 2006 was verified with the Student´s t-test for independent variables. The statistical significance of differences between the number of girls classified to each group in respect of the whole population surveyed in the year 1986 and 2006 was determined with the ?2 test.
In the investigated twenty-year period, analyses demonstrated an increased incidence of body mass deficiency and excess in the surveyed girls. Greater differences between the generations in the incidence of underweight, overweight and obesity were observed in the urban girls, compared to their rural peers. In addition, more significant differences in body mass deficiency and excess were noted in the youngest girls from schools of the Lubelskie Province.
It may, therefore, be speculated that the differences in the economic status of Lubelskie Province inhabitants influenced a lower number of girls with appropriate BMI values as well as increased percentages of girls with body mass deficiency and excess.
波兰人口经济状况日益加大的不均衡现象切实反映在儿童和青少年营养状况的差异上。
本研究的目的是确定在二十年时间跨度内，体重指数（BMI）值正常的女孩及其体重过轻、超重和肥胖同伴的人口规模变化。
1986年进行的调查涵盖了17586名女孩，而二十年后进行的调查涵盖了9540名女孩。测量了女孩的身高和体重，从而能够计算她们的体重指数（BMI）值。根据国际肥胖问题工作组的指导方针，从生物材料中选出体重处于III度体重过轻（I组）、II度体重过轻（II组）、I度体重过轻（III组）、BMI值正常（IV组）、超重（V组）和肥胖（VI组）的女孩。用独立变量的学生t检验验证1986年和2006年获得的平均值之间差异的统计学意义。用卡方检验确定1986年和2006年调查的整个人口中归入每组的女孩数量之间差异的统计学意义。
在调查的二十年期间，分析表明被调查女孩中体重不足和超重的发生率有所增加。与农村女孩相比，城市女孩在体重过轻、超重和肥胖发生率方面的代际差异更大。此外，卢布林省学校最年幼女孩的体重不足和超重差异更为显著。
因此，可以推测卢布林省居民经济状况的差异影响了BMI值正常女孩的数量减少，以及体重不足和超重女孩百分比的增加。
