Abstract

Glavni cilj ovog rada je opisati trend kretanja medijana indeksa tjelesne mase kod učenika petih do osmih razreda jedne osnovne škole u gradu Zagrebu u razdoblju od 1999. do 2014. godine. Uzorak ispitanika čine učenici (N=3,567; 1,652 učenice i 1,915 učenika) petih do osmih razreda osnovne škole “Ivan Cankar” u gradu Zagrebu. Temeljem prikupljenih podataka mase i visine tijela na početku školske godine izračunat je indeks tjelesne mase. Ova metoda koristi se kao pokazatelj stupnja uhranjenosti osobe. Za prikaz kretanja indeksa tjelesne mase korištena je regresijska analiza. Podaci pokazuju da je kod većine razreda uočljiv rastući trend indeksa tjelesne mase, ali statistički značajan je samo kod učenika šestih i sedmih razreda. Kod učenika šestih razreda regresijska analiza pokazuje statistički značajan (p=0,019) trend porasta medijana indeksa tjelesne mase tijekom promatranog razdoblja u iznosu od 0,08 kg/m2 godišnje. Kod učenika sedmih razreda utvrđen je statistički značajan (p=0,004) trend porasta medijana indeksa tjelesne mase u iznosu od 0,14 kg/m2 godišnje.

Abstract (english)

The main aim of this study was to describe the trend of median body mass index in students from fifth to eighth grade in a primary school in Zagreb in the period from 1999 to 2014. The sample consisted of students (N=3.567; 1.652 female and 1.915 male students) from fifth to eighth grade of primary school „Ivan Cankar“ in the city of Zagreb. Body mass index was defined at the beginning of the school year on the basis of the collected data on body mass and body height of the students. This method was used as an indicator of the nutritional status
of a person. Regression analysis was used in order to review the trend of body mass index. The results have shown that among the majority of the classes increase in body mass index was visible, but it was statistically significant only in the male students of the sixth and seventh grade. The regression analysis of the sixth graders showed a statistically significant (p=0.019) increase of the median of body mass index (0.08 kg/m² per year) during the period of research. As for the seventh graders, there was a statistically significant (p=0.004) increase of median of body mass index (0.14 kg/m²) per year.
