Abstrakt		Background. The recommended number of daily meals is three to five. The aim of this study was to establish the number of meals, daily consumed by secondary school students from Ljubljana, and the relationship with nutritional and other habits, including bad habits, demographic and socio-economic characteristics of the secondary school students and their body mass index. Methods. In 1999, an cross-section epidemiological study was performed on a proportional sample of 296 pupils attending the third class of Ljubljana secondary schools. The applied dietary data collection methods were the survey and the 24-hour dietary recall. The body mass index was calculated on the basis of the measured body height and body mass values. The Chi-square test, t-test, variance analysis and the multivariant linear regression method were used for the analysis. Results. The students consume 3.1 G meals per day on average (boys 3.44, girls 2.87). The students who reported a smaller number of meals per day consume statistically significantly less fruit, vegetables, milk, milk products and fish. They take hot meals less frequently, consume less often all daily meals, their daily meals are of a poorer quality in respect to their composition, they eat less often their meals in a sitting position, they feel a greater difference in diet between working week days and weekends, their regular nourishment is more influenced by school obligations, they have poorer knowledge of healthy dietary practices, smoke more often, are less satisfied with their weight, are less physically active and girls sleep less at nights. The inverse proportional relationship between the number of daily meals and the body mass index was not statistically significant. The multivariant linear regression model explained the low variance percentage (R2 - 0.28).
Izvleček		Izhodišča. Priporočeno število dnevnih obrokov je od tri do pet Želeli smo ugotoviti število obrokov, ki jih dnevno zaužijejo ljubjanski srednješolci, in povezave s prehranskimi ter drugimi navadami in razvadami, demografskimi in socialnoekonomskimi značilnostmi srednješolcev in indeksom telesne mase srednješolcev Metode. Presečna epidemiološka študija je bila izvedena v letu 1999 na proporcionalnem vzorcu 296 dijakov trejih letnikov ljubljanskih srednjih šol. Uporabljeni sta bili metodi ankete in jedilnika preteklega dne. Na podlagi izmerjenih vrednosti telesne višine in telesne mase je bil izračunan indeks telesne mase. Za analizo so bili uporabljeni test hi-kvadrat, t-test, analiza variance in multivariatna linearna regresijska metoda. Rezultati. Dijaki v povprečju zaužijejo 3,16 obroka na dan (fantje 3, 44, dekleta pa 2,87). Dijaki, ki zaužijejo manjše število dnevnih obrokov; uživajo statistično značilno manj sadja, zelenjave, mleka in mlečnih izdelkov in rib, manj pogosto uživajo tople obroke, manj pogosto uživajo vse dnevne obroke, imajo glede na sestavo slabšo kakovost dnevnih obrokov, redkeje uživajo hrano sede, bo j občutijo razliko v prehrani med delavnikom in za vikend, pri redni prehrani jih bolj ovirajo šolske obveznosti, imajo manj znanja o zdravi prehrani, pogosteje kadijo, manj so zadovoljni s svojo telesno težo, manj so telesno aktivni, dekleta pa manj spijo čez noč. Med številom dnevnih obrokov in indeksom telesne mase obstaja šibka obratnosorazmerna povezava. Multivartatni linearni regresijski model je pojasnil nizek odstotek variance (R2 - 0,28). Zaključki. Povprečno število dnevnih obrokov, ki jih zaužijejo dijaki, je na spodnji meji priporočil, povprečno število dnevnih obrokov, ki jih zaužijejo dijakinje, pa je pod priporočili. Preiskovane spremenljivke so sicer povezane s številom dnevnih obrokov.
