Childhood obesity is a disease of civilization and its incidence has increased tenfold worldwide in 40 years. We conducted a questionnaire survey to assess the lifestyle factors of the students of grades 4-8 of the Esterházy Móric Language Teaching German Nationality Primary School in Csákvár in relation to obesity. 164 students completed the questionnaire. Overfed, overweight and morbidly obese children together represent 37% of the sample. In terms of gender, 14% and 23% of boys and girls, respectively, are overnourished, 11% of boys and 14% of girls, respectively, are overweight, and 4% and 6%, respectively, are morbidly obese. The percentages of overnutrition, overweight, and morbid obesity combined are similar across grades. The highest rate, 42%, is found in 5" grade. ln assessing students' attitudes toward their own health and its importance, only 35% of the 164 respondents said their health was vert' important to them, 34% said it was important, 25% said it was moderately important, 5% said it was less important, and 0.6% said it was not important at all. Boys and girls overwhelmingly (53% and 48%, respectively) believe they are only partially eatíng right. The státement "Healthy eating equals dieting" was considered false by 68% of students and true by 32%. Regarding the impact of obesity on health, more than half of the students, 55%, are aware of the causal relationship between obesity and diabetes. 25% of students eat three meals a day. Eating five meals a day is not really typical among young people, only 12%, and 16% do not keep track of how many times they eat a day. Daily fruit consumption is typical for 35% of the total sample, and daily vegetable consumption is typical for 28%. Soft drinks are consumed mostly once a week by young people (34%).
