ABSTRACT

The aim of the study was to evaluate the frequency of consumption
of foods, which are sources of vitamin D and calcium, among secondary school
youth depending on sex, body weigh status and physical activity. The investigated
population included 618 students (305 girls and 313 boys) aged 16 to 20 years,
from 8 randomly selected secondary schools in the city of Poznań. Dietary intake
data was obtained using a Food Frequency Questionnaire (FFQ), and physical activity
was assessed with the use of the International Physical Activity Questionnaire
(IPAQ). It was found that boys in comparison to girls consumed more frequently
(p < 0.05) products containing higher amounts of vitamin D and calcium (hard
cheese, fish, fish preserves and seafood, eggs).
Also young subjects with higher level of physical activity in comparison to less
active ones consumed more often (p < 0.05) products rich in vitamin D and
calcium (milk, yoghurt, kefir, buttermilk, beef, veal). Overweight and obese
students declared more rarely (p < 0.05) consumption of some foods rich in
calcium as well as sweets in comparison with students with
a proper body mass. The findings of this study show that overweight and
obese, as well as physically non-active students, especially girls, may be at
risk of an insufficient supply of calcium and vitamin
D. Moreover, it seems that the estimation of dietary habits of overweight
and obese students might be burdened with a respondent error.

Key words: vitamin D, calcium, students, FFQ.
