Posturalni status i telesni sastav dece školskog uzrasta
Introduction: Contemporary living circumstances offer possibilities of aprogress in almost all spheres of life of one child, but there are also somenegative aspects such as hypo kinesis, postural disorders, and obesity. Resultsof previous researches show that postural disorders and state of bodycomposition in a period of an early adolescence represent one of the fastestgrowing health disorders in this age. In accordance with this, the main goalof this research is to establish the condition and difference of the posturalstate of the spine and body composition of children of seniour classes ofprimary school as well as connection and influence of body composition andpostural status.Method: The sample of respondents was comprised of 484 children ofprimary-school age of both genders from the territory of the town Knjazevac.This municipality represents a group of municipalities up to 30 000inhabitants and such are located on the 49,6% of the territory of Serbia.Instruments used for gathering measured parametres were: anthropometar(SECA model 284; SECA, Hamburg, Germany), an instrument forassessment of body composition Inbody 770, ( Inbody Co, Seoul, Korea) andan instrument for diagnosing of postural status of the spine ( Formetric 4DSystem, Diers, Germany). For the analysis of the gathered data were used:descriptive and percentage analysis, Hi square test for testing independencewith Z test supplement was used to determine differences, ANOVA test wasused to determine trend of changes, Eta coefficient was used to determinecorrelational values, and discriminatory analysis to determine thecontribution of parametres of body composition on postural status of thespine.Results: The results have indicated that in the sagittal plane the percentageof postural disorders was present at 69,2% of the respondents (Male =67,5%;Female 71,1%), while that percentage in the frontal plane was 39,5% (M=32,5; F=47%). Also, a statistically significant difference was observed bygender in the prevalence of the postural disorders and normal posture onlyin the frontal plane (М=0.000; Ж=0.393) while this was not observed in thesagittal plane of the spine (М=0.000; Ж=0.000). By analyzing the results,only statistically significant difference between genders in the state ofpostural status of the frontal plane was observed (total=0.001; by classesV=0.053; VI=0.155; VII=0.186; VIII=0.050) while in the postural status ofthe sagittal plane, a statistically significant difference between genders wasnot observed (total=0.383; by classes V=0.359; VI=0.596; VII=0.009;VIII=0.257). By ANOVA analysis was determined the presence of astatistically significant trend of changes in all analyzed parametres for theevaluation of body composition except PFM (sig=0.145). Eta coefficient hasindicated that there is a statistically significant correlation of the posturalstatus of the spine in the frontal plane and all parametres of body composition,while with the postural status in the sagittal plane variables of bodycomposition that do not correlate are BMFkg (sig=0.072) and PBF(sig=0.070). The results of the discriminatory analysis have indicated to theexistence of the statistically significant contribution of the paratmetres ofbody composition (BFMkg=.875; PBF=859; RSMM=-.730; PFFM=-.658)on the postural status in the sagittal plane of the spine, while the greatestcontribution were recorded in the variables (BFMkg=-.638; PBF=-.692;RSMM=.734; PFFM=.615) on the postural status in the frontal plane.Conclusion: It may be concluded that there is high prevalence of the posturaldisorders of the spine in children of the senior classes in primary school,primarily in the sagittal plane and that there is a gender difference in theprevalence of the spinal deformities in certain regions. Also, in this ageperiod, based on the results of trend analyses, gender differences in bodycomposition parametres are clearly indicated: muscle mass, body fat mass aswell as different influence of the parametres of body composition on the stateof the postural status of the spine. In accordance with the findings obtained,it is clear that the approach to solving the problem of the current state of thepostural disorders on the spine and the parametres of body composition mustbe different according to gender but also according to age.
