Background/Aims: The prevalence of overweight and obesity in children and adolescents is increasing worldwide, and this condition is a risk factor for cardiovascular mortality. The aim of this study was to assess the prevalence of overweight and obesity among the 3–18-year-old population in Szolnok City and the surrounding areas. Methods: Anthropometric data from healthy, white individuals recruited from nursery, elementary, and secondary schools were used to assess the prevalence of obesity and overweight in Szolnok City and the surrounding area, Jász-Nagykun-Szolnok county, Hungary. Healthy subjects numbering 6,824 (54% boys) were included; overweight and obesity were defined according to the relevant guidelines. Results: Overweight individuals constituted 13.4% of the population and 6.6% were obese. The total prevalence was higher in boys (21.6%) than in girls (18.1%). The peak of the prevalence was observed at age 10 in both sexes (boys 33%, girls 27%) followed by a gradual decrease, which was more significant in the case of girls. Conclusions: On the basis of the recent Hungarian data, we have not detected any changes in overweight and obesity in the age group 3–9 years and we have found a significant decrease in the age group 7–14 years. Prevention of overweight and obesity in early childhood is essential.
