Abstract

Percentilne krivulje služe za procjenu rasta i razvoja djece tako što se djeca rangiraju na percentile i uspoređuju s djecom iste dobi i spola, odnosno referentnom skupinom. CDC krivulje su međunarodno priznate krivulje koje se koriste diljem svijeta, a neke države kao i Hrvatska posjeduju nacionalne krivulje. Cilj istraživanja bio je usporediti HR krivulje sa CDC krivuljama i ustanoviti dali su HR krivulje usklađene sa CDC krivuljama te time i objektivne u kliničkoj primjeni, za procjenu uhranjenosti. Ispitivana skupina su bila djeca iz Zagreba u dobi od 6 do 9 godina, te se na temelju izračunatih vrijednosti indeksa tjelesne mase određivao percentil na obje krivulje BMI za dob (CDC i HR). Uhranjenost prema percentilnim vrijednostima iz dviju krivulja uspoređena je prikazom normalne distribucije, frekvencija i primjenom Bland-Altmanove metode. Normalna distribucija prikazivala je odstupanja HR krivulja od CDC krivulja, dok prema Bland-Altman metodi nije bilo značajnih odstupanja i razlika između krivulja što je potvrda kako HR krivulje dobro procjenjuju uhranjenost djece te su rezultati u skladu sa CDC krivuljama.

Abstract (english)

Percentile growth charts are used to estimate the growth and development of children by classifying them to percentiles and comparing them with children of the same age and gender, their referral group. CDC growth charts are internationally recognized curves used throughout the world while some countries as well as Croatia have also national curves (CRO). The aim of the study was to compare the CRO growth charts with the CDC growth charts and determine whether the CRO curves are in accordance with the CDC curves and applicable in clinical application for estimation of nutritional status. The examined group were children from Zagreb aged 6 to 9 years old and their body mass index was evaluated by use of CDC and CRO percentile growth charts. Evaluated percentiles were compared using normal distribution of frequencies and by use of Bland-Altman method. The normal distribution showed that the CRO curves differ from the CDC curves, whereas the Bland-Altman method did not show significant deviations and the difference between the curves. This finding confirms the objectivity of the CRO growth charts in the estimation of children's nutritional status.
