To analyze the obesity, overweight, and thinness trends among Brazilian schoolchildren by sex, age group, and type of school according to World Health Organization (WHO) and International Obesity Task Force (IOTF) criteria.
We conducted four surveys between 2002 and 2018/19 involving schoolchildren aged 7-14 years from a state capital in southern Brazil. Weight status was classified using both WHO and IOTF criteria.
In the total sample, obesity prevalence based on the IOTF and the WHO criteria were 72% and 44% higher in 2018/19 compared with 2002, respectively. Over the whole period, the obesity prevalence increased among children (WHO: 10.1% vs. 14.1%; IOTF: 5.0% vs. 8.3%), and those from public schools (WHO: 10.5% vs. 16.4%; IOTF: 5.6% vs. 10.1%). There was no significant reduction in thinness prevalence over the analyzed period.
Obesity prevalence remains on an upward trend in a state capital in southern Brazil, especially among children from public schools. A higher prevalence of overweight and obesity was observed using the WHO criteria compared with IOTF criteria.
根据世界卫生组织（WHO）和国际肥胖特别工作组（IOTF）标准，分析巴西学童按性别、年龄组和学校类型的肥胖、超重和消瘦趋势。
我们在 2002 年至 2018/19 年期间进行了四项调查，涉及巴西南部一州首府 7-14 岁的学童。采用 WHO 和 IOTF 标准对体重状况进行分类。
在总样本中，2018/19 年基于 IOTF 和 WHO 标准的肥胖患病率分别比 2002 年高出 72%和 44%。在整个时期内，儿童（WHO：10.1%对 14.1%；IOTF：5.0%对 8.3%）和公立学校学生（WHO：10.5%对 16.4%；IOTF：5.6%对 10.1%）的肥胖患病率均有所增加。在此分析期间，消瘦的患病率没有显著下降。
在巴西南部的一个首府，肥胖患病率仍呈上升趋势，尤其是公立学校的儿童。与 IOTF 标准相比，WHO 标准观察到超重和肥胖的患病率更高。
