Ciljevi: Ciljevi istraživanja su: prikazati stanje uhranjenosti bolesnika liječenih na Klinici za dječje bolesti Kliničke bolnice Split, utvrditi povezanost kliničkih pokazatelja stanja uhranjenosti s osnovnom bolešću i duljinom liječenja te usporedno prikazati dva različita pokazatelja stanja uhranjenosti: debljinu kožnih nabora i BMI (od engl. body mass index). Metode: U istraživanju su sudjelovala 632 bolesnika, 332 ženska i 300 muških, u dobi od 3. do 20. godine života. Bolesnicima smo izmjerili tjelesnu masu i tjelesnu visinu nakon prijma i pri otpustu, izračunali BMI i kaliperom izmjerili debljinu kožnih nabora. Rezultati: 7,91% djece bilo je neishranjeno, 10,60% preuhranjeno, a 7,75% rizično za preuhranjenost. Među bolesnicima je bilo statistički značajnih razlika u stanju uhranjenosti u odnosu na osnovnu bolest. Nalazi debljine kožnih nabora i BMI-a statistički se značajno ne razlikuju (p>0,05). Z-vrijednostima pokazali smo promjene tjelesne mase po dobnim skupinama. Zaključak: U usporedbi s rezultatima drugih autora, neishranjenost bolesnika liječenih na Klinici za dječje bolesti KB Split je rijetka. Budući da i neishranjenost i preuhranjenost mogu značajno utjecati na ishod bolesti, kao i na zdravlje u odrasloj dobi, svoj hospitaliziranoj djeci treba procijeniti stanje uhranjenosti. Bolesnike s poremećajem uhranjenosti treba na vrijeme prepoznati i liječiti.Aims: The objectives of the study are: to determine the nutritional status of patients hospitalized at the Department of Pediatrics in Split Clinical Hospital, to show the relationship between the clinical signs of nutritional status and the basic disease and length of hospital stay and a comparison of two different signs of nutritional status: skinfolds and BMI (body mass index). Methods: We studied 632 children, 332 female and 300 male, aged 3 years to 20 years. We measured height and weight, BMI, and skinfolds, with a caliper, of the patients at admission, and at discharge from hospital. Results: 7.91% of children were underweight-for-age, 10.60% were overweight-for- age and 7.75% were at risk for overweight-for-age. Between the patients there were statistically significant differences between nutritional status and the principal disease. There were no statistically significant differences between skinfolds and BMI (p>0,05). Z values express body mass changes in various age groups. Conclusions: In comparison with other authors\u27 results, low weight in patients hospitalized in the Clinical Hospital Split is not so frequent. Since overweight and underweight-for-age can have a great influence on the course of the disease and on health later, in adulthood, we have to estimate the nutritional status of all hospitalized children, and also to recognize and treat the existing problem
