Indicators of nutritional status and physical activity of primary school students

Sve češći sedentarni način života i pojava pretilosti kod učenika ukazuju na potrebu da se utvrdi njihova uhranjenost i tjelesna aktivnost. Cilj istraživanja bio je utvrditi kod učenika razredne nastave s obzirom na spol pokazatelji uhranjenosti, pokazatelji tjelesne aktivnosti i povezanost razine tjelesne aktivnosti s pokazateljima uhranjenosti. Uzorak se sastojao od 33 učenika i 33 učenice četvrtih razreda Osnovne škole dr. Jure Turića u dobi od prosječno 10 godina. Na temelju dobivenih informacija može se utvrditi potreba za povećanjem tjelesne aktivnosti kod učenika, ako većina učenika ima prekomjernu tjelesnu masu. Uzorak varijabli činio je skup 6 antropometrijskih morfološki varijabli, 4 postupka izračunavanja pokazatelja statusa uhranjenosti i Upitnik o tjelesnoj aktivnosti. Dobiveni podaci u istraživanju uspoređeni su s metrijskim karakteristikama i analizirani metodama deskriptivne statistike. Za utvrđivanje statistički značajnih razlika učenika i učenica primijenjen je t-test i kanonička diskriminacijska analiza. S obzirom na spol utvrđene su razlike u manifestnim mjerama morfoloških antropometrijskih obilježja pokazatelja uhranjenosti i tjelesne aktivnosti. Povezivanjem rezultata masnog tkiva, ITM i tjelesne aktivnosti rezultati pokazuju da su učenici pretežno normalne tjelesne mase i dovoljno su tjelesno aktivni (učenici u svemu imaju malo bolje rezultate u odnosu na učenice).The increasingly sedentary lifestyle and the occurrence of obesity in students indicate the need to determine their nutritional status and physical activity. The study aims to identify nutritional status indicators and physical activity indicators as well as to examine the correlation between physical activity level and nutritional status indicators of primary school students with regard to gender differences. The study was conducted on a sample of 33 male and 33 female fourth grade students of the Primary School dr. Jure Turić with an average age of 10 years. Based on the collected information, the need for increasing students' physical activity can be identified whether the majority of students are overweight. The sample of 10 variables consisted of a set of 6 anthropometric morphological variables, 4 procedures for calculating nutritional status indicators and the Physical Activity Questionnaire was used. Collected data in the research were compared with metric characteristics and were analysed by descriptive statistics methods. T-test and canonical discriminant analysis were applied to determine statistically significant differences between male and female students. Differences were identified in manifesting measures of morphological anthropometric characteristics indicators of nutritional status and physical activity of students regarding gender. The correlation of adipose tissue results, BMI results and physical activity results showed that students were predominantly of normal body weight and with enough physical activity (male students have slightly better results than female students)
