Vitamin content in the diet among 14-15-year-old teenagers depending on the BMI value.

BACKGROUND In a period of intensive growth and development, both a deficiency and an excess of nutrients may have negative consequences on health. In the case of vitamins, an ongoing deficiency can result which have a direct effect on public health. METHODS The research included all third year middle school pupils. With the assistance of the person conducting the research, a questionnaire was completed about consumption of food products consumed every day for a period of 7 days. Energy and nutrient requirements were defined individually for each child in terms of RDA. RESULTS The daily intake of group B vitamins was exceeded both in the boys' group and the girls' group. The daily intake of vitamin C and folates was higher in the boys' group than in the girls' group, but did not meet the required daily intake in any of the groups studied. In all boys' groups, the intake of vitamin D covered less than 30% of the required daily amount. It has been shown that there is a statistically significant influence of the intake of vitamins on body mass. In the girls' group, the most common statistically significant differences were between the group of underweight girls and the groups of girls with correct body weight and overweight girls. CONCLUSIONS Insufficient intake of vitamins is observed most often in underweight adolescents. The incorrect amount of vitamins in the diet requires the implementation of action to improve the dietary preferences of adolescents.
