Abstract:The main goal of this research was to determinegender-related differences in some parameters of body composition caused by the nutritional status of preschool children, and group differences within subsamples caused by the nutritional status of both genders. The total sample consisted of 188 participants,boys (n=107) and girls (n=81) from Belgrade,with average values of body height BH=124.59cm±5.76 and body mass BM=24.32kg±3.11, average age6.39±0.44 years. Body composition was assessed using the InBody 230 device. The main parameters of descriptive statistics were calculated. The MANOVA method was used to determine gender differences in the entire sample, and the ANOVA method was used to determine individual differences. A series of Post-Hoc Bonferroni tests were performed to determine between which groups significant statistical differences existed. This study provides encouraging findings when it comes to a satisfactory percentage of normally nourished children of both genders, but it should also point to a certain trend in the rise of obese and overweight children who make up almost 17% of the total sample. The differences observed in the girls’subsample may indicate girls enter the pre-pubertal phase earlier than boys, based on the differences in the amount of body fat tissue, but also always greater muscle mass in theboys' subsample, and lower average values of body mass and the Body Mass Index in the girls' subsample. Constant monitoring of children’s nutritional status and physical abilities every six months or oncea year is recommended.
Apstrakt: Cilj istraživanja bio je da se utvrdi postojanje polnih razlika u određenim parametrima telesne kompozicije koje su uzrokovane stanjem uhranjenosti dece predškolskog uzrasta, te grupne razlike unutar subuzoraka prouzrokavane njihovim stanjem uhranjenosti za oba pola. Ukupan uzorak sačinjavalo je188 ispitanika sa prosečnim vrednostima telesne visine TV=124.59cm±5.76 i telesne mase TM=24.32kg±3.11, prosečnog uzrasta 6.39±0.44 godina, podeljenih po polu na dva subuzorka i to: dečaka (n=107) i devojčica (n=81)iz Beograda. Telesna kompozicija procenjena je pomoću bioelektrične impendance, uređajem InBody 230. Izračunati su glavni parametri deskriptivne statistike. Metoda MANOVA korišćena je za utvrđivanje razlika po polu u celom uzorku, dok je metoda ANOVA korišćena za utvrđivanje individualnih razlika. Izvršena je serija Post-Hoc Bonferroni testova kako bi se utvrdilo između kojih grupa postoje značajne statističke razlike. Ova studija daje ohrabrujuće rezultate tj.,zadovoljavajući postotak normalno uhranjene dece oba pola, ali isto tako ukazujena izvesni trend u rastu rizično gojazne i gojazne dece od skoro 17% ukupnog uzorka. Grupne razlike za subuzorak devojčica ukazuju na mogućnost bržeg ulaska u predpubertetsku fazu, utvrđenu na osnovu različitosti količine masnog tkiva u organizmu, ali i veće količine mišićne mase u subuzorku dečaka, te manjih prosečnih vrednosti telesne mase i indeksa telesne mase u subuzorku devojčica. Preporučuje se stalni monitoring stanja uhranjenosti i fizičkih sposobnosti dece na periode od šest meseci do godinu dana.
