Secular trend in childhood obesity is a well-known phenomenon, and it is important to monitor it in cross-sectional studies. The study aim was to estimate prevalence of obesity and overweight in Polish 7- to 9-year-old children and to compare the results with a French study based on the same protocol.
The study was conducted in 2001 according to the protocol of the European Childhood Obesity Group. Height and weight were measured, and BMI was calculated to define nutritional status in a randomly selected group of 2916 (1445 girls and 1471 boys) primary school children. Obesity and overweight were estimated according to International Obesity Task Force references with curve for obesity and overweight passing through 30 and 25 kg/m(2) at age 18, respectively.
Overweight (including obesity) was found in 15.4% of Polish children (in 15.8% of girls and 15.0% of boys) and obesity in 3.6% (3.7% of girls and 3.6% of boys) compared with 18.1% of overweight and 3.8% of obese children in French study. There was no significant difference in nutrition status between Polish and French children except for higher frequency of overweight in French 9-year-old boys. The same trend of decreasing overweight through age classes was observed in both populations.
The prevalence of obesity and overweight (including obesity) in prepubertal children estimated in two European countries according to the same protocol and using the same references showed little differences between the two populations despite higher prevalence of obesity in Polish than French adults.
儿童肥胖的长期趋势是一个众所周知的现象，在横断面研究中对其进行监测很重要。本研究的目的是估计波兰7至9岁儿童肥胖和超重的患病率，并将结果与一项基于相同方案的法国研究进行比较。
该研究于2001年按照欧洲儿童肥胖研究小组的方案进行。对随机抽取的2916名（1445名女孩和1471名男孩）小学生测量身高和体重，并计算体重指数（BMI）以确定营养状况。根据国际肥胖特别工作组的参考标准估计肥胖和超重情况，肥胖和超重曲线分别在18岁时通过30和25kg/m²。
波兰儿童中15.4%超重（包括肥胖）（女孩为15.8%，男孩为15.0%），肥胖率为3.6%（女孩为3.7%，男孩为3.6%），而法国研究中超重儿童为18.1%，肥胖儿童为3.8%。波兰和法国儿童的营养状况没有显著差异，只是法国9岁男孩超重的频率更高。在两个人群中都观察到了随着年龄增长超重率下降的相同趋势。
根据相同方案并使用相同参考标准，在两个欧洲国家估计的青春期前儿童肥胖和超重（包括肥胖）患病率显示，尽管波兰成年人的肥胖患病率高于法国，但两个人群之间差异不大。
