The consumption and amounts of a variety of food products used in a diet affect the incidence of anemia and different levels of nutritional status among school-age children. The prevalence of food intake comprised of fats, carbohydrates and sodium (salt) is a significant contributing factor to the incidence of excessive weight. Apart from nutrition, a leisure-time physical activity and the time spent in front of the TV or computer may contribute to an increase in anemia and obesity rates. The objective of this paper was to examine nutritional status, dietary habits and anemia among school-age children in the central Serbia region (the city of Kragujevac). It was established that 47.3% of the surveyed children fell into the normal weight group, 24.5% of the children are considered to be at risk of being overweight, 21.4 % of the children are considered as obese, whereas 6.8% of the children fell into the under-weight group. The incidence of anemia was noted in 10.8% of the cases, whereas anemia in obese children was observed in 21.6% of the cases (n=114; during the school year of 2014-2015). The obtained results show a statistically significant correlation between an increase in the consumption of fast food and anemia in children, whereas the amount of time children spend in front of the TV is also associated with the higher percentage of anemia and obesity.
