Nutritional knowledge of the preschool staff from Nowy Sącz and the vicinity. Part 3. Rich sources of vitamins and minerals
Food and Nutrition Department of the Eugeniusz Piasecki University School of Physical Education in Poznań

Summary
Aim. The aim of this study was to assess knowledge about rich sources of vitamins and minerals in preschool staff from Nowy Sącz and the vicinity.
Material and methods. Questionnaires on the knowledge about rich sources of vitamins and minerals were filled in by 84 women who worked in eight preschools in Nowy Sącz and the vicinity. The studied population was divided according to educational status. The SPSS 12.0 PL for Windows computer programme was used to carry out the statistical analysis. Mean percentages of correct answers were calculated in order to compare the level of knowledge of the studied population.
Results. Educational status had statistically significant influence on the answers to nine questions, including one question concerning rich sources of vitamin A, B vitamins, calcium and iron, as well as five questions concerning rich sources of vitamin C. The mean percentage of correct answers to all of the questions was 18.6% in the staff with vocational education, 34.1% in the staff with secondary education and 32.1% in the staff with higher education.
Conclusions. Nutritional knowledge about rich sources of vitamins and minerals in the studied preschool staff was insufficient, irrespective of the educational status. Low level of nutritional knowledge of the studied women shows the need to organise obligatory nutrition courses for the preschool staff.
INTRODUCTION
In our previous articles we pointed to the considerable influence of nutritional knowledge of both parents (1, 2, 3) and preschool staff (4, 5) on preschool children's dietary behaviour. A very important area of this knowledge, which makes it possible to compose balanced meals and the whole daily food ration for the child, is the issue of rich dietary sources of vitamins and minerals. These nutrients are biologically active and play a crucial role in human metabolism, especially in the first stages of life. The few studies, published so far, on the knowledge about rich dietary sources of vitamins and minerals among parents of preschool children (3, 6) showed low level of knowledge in the studied populations. The question arises whether preschool staff has better knowledge in this field.
AIM
The aim of this study was to assess knowledge about rich sources of vitamins and minerals in preschool staff from Nowy Sącz and the vicinity.
MATERIAL AND METHODS
Questionnaires on the knowledge about rich sources of vitamins and minerals were filled in by 84 women who worked in eight preschools in Nowy Sącz and the vicinity. The questionnaire was used in our previous studies (3, 6, 7, 8). The studied population was divided according to educational status. The characteristics of the studied women were presented in our previous article (4).
The SPSS 12.0 PL for Windows computer programme was used to carry out the statistical analysis. Qualitative variables were presented in contingency tables. Statistical significance was determined using Pearson's chi-square test, except for the variables with more than 20% of cells with an expected frequency of less than five. In this case, the Kruskal-Wallis H test was used. The level of significance was set at p≤0.05. Moreover, mean percentages of correct answers were calculated in order to compare the level of knowledge of the studied population.
