The aim set for the Thesis purposes was to map the problem of excess weight and obesity of primary school pupils both in the town and the country in 4th till 9th classes; mainly their eating habits and movement activities. This aim was fulfilled. In accordance with the aim hypotheses were set. The hypothesis 1 was: Excess weight will increasingly grow in children with bad eating habits. On the basis of the research this hypothesis was disconfirmed. The children with the considered problem have almost the same eating habits as the children with normal weight. The hypothesis 2 was: Excess weight will increasingly grow in children with low movement activities. On the basis of the research this hypothesis was partially confirmed. The children with the considered problem take part in sport bees 20% less frequently. In the remaining questions regarding movement activities, the evaluated results are almost the same for both categories of children. The obesity problem is not avoiding even the present time, either. Obesity has become a serious problem in all developed countries where the Czech Republic belongs as well. This problem does not involve the adult population only. Recently, we can meet with excess weight or obesity in children more often. Number of children with excess weight in this country keeps growing. This thesis of experts is confirmed even by the survey performed for this Thesis purposes. It is quite clear from the results that no fewer than 140 children, which equals 20 % from the sample surveyed, have the problem with excess weight or obesity. The allocation of excess weight and obesity problem was as follows. The highest obesity occurrence was within the age category of the 12-year-old, where 14 % recorded the excess weight. Within the age category of the 15-year-old 12 % recorded obesity. Of the total number with excess weight the total 38 % boys live with excessive weight and 25 % suffer obesity. As for girls, 18 % suffered excess weight and 19 % of them were obese. When comparing children with excessive weight in the country and the town it is obvious that in villages there are considerably more children having the problem of increased weight. 68.5 % village children with obesity or excessive weight against 31.5 % children from towns. Obesity of children is a problem of societies in a lot of countries. However it is just unsuitable eating, life style, in particular lack of movement which in the absolute majority bear their shares in the redundant kilograms. Therefore prevention is very important. Such prevention should be aimed at children and their parents from the babyhood.
