Summary The objective of this paper was an evaluation of change in prevalence of overweight and obesity in Czech children, and a comparison of cut‐off points for body mass index references from the Czech Republic (CzR), International Obesity Task Force and WHO. The authors conducted a survey in 7‐year‐old children, and compared data from 1951, 1981, 1991, 2001 and 2008 (WHO cut‐offs). 2008 data were evaluated according to different cut‐offs. Results showed that since 1951 in boys, overweight prevalence increased from 13.0% in 1951 to 26.8% in 2001, in girls from 10.9% to 22.9%. Obesity increased in boys from 1.7% to 8.3%, in girls from 1.7% to 6.9%. From 2001 to 2008 obesity in boys increased; obesity in girls and overweight in both genders decreased. In 2008 cohort the following values were found: overweight and obesity: CzR criteria, percentage was lowest (14.8% boys and 11.1% girls); WHO criteria, highest prevalence (23.5% boys and 19.5% girls); obesity: lowest ratio International Obesity Task Force criteria (4.4% boys, 3.3% girls), highest ratio boys WHO criteria (10.0%), girls CzR criteria (5.0%). Overweight and obesity prevalence increased in 7‐year‐old Czech children since 1951; since 2001 prevalence is plateauing with exception of boys. Using different body mass index references resulted in marked differences in overweight and obesity prevalence.
