Background: Surveillance of childhood obesity is essential to guide preventive policies and interventions.Aim: To analyse trends in overweight and obesity by socioeconomic status (SES) in Argentinian schoolchildren during the last decade.Subjects and methods: Two cross-sectional studies in schoolchildren aged 6-12 years were compared. The first study was conducted in 2005/07 (n = 1418) and the second one in 2015/16 (n = 1366). Overweight and obesity were estimated by the International Obesity Task Force (IOTF) cut-offs. The type of school (public/private) and parental education level were used as measures of SES. Data were analysed by linear and logistic regression with survey year, type of school, parental education level, and sex as independent variables.Results: From 2005 to 2016 overweight and obesity increased by 7.3% and 5.0%, respectively. The change was significantly higher in boys (9.6% and 8.3%) and girls (9.6% and 5.4%) from public schools, and in children whose fathers had low (10% and 8.3%) and middle (9.0% and 5.5%) education levels. No significant changes were found in children attending private school or those whose fathers had a higher education level.Conclusions: Obesity is still increasing in this population. SES disparities are strongly associated with this trend, with stabilisation in children from high SES.

儿童肥胖的趋势反映了阿根廷的社会经济地位。

背景：对儿童肥胖症的监测对于指导预防政策和干预措施至关重要。目的：根据过去十年中阿根廷学龄儿童的社会经济状况（SES）分析超重和肥胖的趋势研究对象和方法：两项针对年龄在学龄儿童中的横断面研究比较了6-12年。第一次研究于2005/07进行（n = 1418），第二次研究于2015/16进行（n = 1366）。超重和肥胖是由国际肥胖特别工作组（IOTF）评估的。学校的类型（公立/私立）和父母的教育水平被用作SES的量度。通过线性和逻辑回归分析数据，以调查年份，学校类型，父母教育水平和性别为自变量。结果：2005年至2016年，超重和肥胖分别增加了7.3％和5.0％。公立学校的男孩（分别为9.6％和8.3％）和女孩（分别为9.6％和5.4％）以及父亲低（10％和8.3％）和中级（9.0％和5.5％）的孩子的变化明显更大。教育水平。在私立学校就读的孩子或父亲受过高等教育的孩子没有发现显着变化。结论：肥胖仍在增加。SES差异与这种趋势密切相关，而高SES儿童的病情稳定。肥胖仍在增加。SES差异与这种趋势密切相关，而高SES儿童的病情稳定。肥胖仍在增加。SES差异与这种趋势密切相关，高SES患儿的稳定也与之相关。
