Abstract
Matematički modeli primijenjeni u nutricionizmu koriste matematički jezik kako bi definirali ili opisali određeni sustav te se mogu koristiti za predviđanje dinamike promjene tjelesne mase. Jednodimenzionalni Heymsfield-ov model razvijen je primjenom modifikacija prethodno razvijenih modela te se može primijeniti i za predviđanja promjene tjelesne mase skupine, ali i pojedinaca. Validacija modela provedena je pomoću podatak triju studija; dvije studije koje prate restrikciju energetskog unosa i jedne studije koja prati prekomjerno hranjenje. Usporedba modela pokazala je bolje predviđanje konačnih, individualnih rezultata promjene tjelesne mase, kao i za slučajeve kalorijske restrikcije i prekomjerno hranjenje. Također se Heymsfield-ov model pokazao pouzdaniji, obzirom na vrlo malu standardnu devijaciju srednje apsolutne pogreške čime je smanjena maksimalna apsolutna pogreška za više od 60%. Upravo ga ove prednosti čine prikladnim za (i) korištenje u procjeni promjene tjelesne mase pojedinaca, (npr. pojedinačnih pacijenata) i (ii) objektivnim za mjerenje usklađenosti s propisanim planom prehrane, tj. energetskim unosom.
Abstract (english)
A mathematical model used in nutrition, use mathematical language to define or describe a particular system and an example of their use is to predict the dynamics of weight change. The one-dimensional Heymsfield's model developed using modifications of previously developed models is in use to predict changes in body weight of a group as well as individuals. Model validation was performed using data from three studies investigating models; two studies that track energy intake restriction and one study that monitors overfeeding. Model comparisons showed better predictions of definitive, individual outcomes of weight change, as well as for cases of calorie restriction and overfeeding. Heymsfield's model also proved to be more reliable, given the very small standard deviation of the mean absolute error, which reduced the maximum absolute error by more than 60%. These advantages make it suitable for (i) use in assessing the weight change of individuals (e.g. individual patients) and (ii) for objective compliance measuring with a prescribed diet plan, i.e. energy intake.
