The aim of the present study was to advance knowledge of the secular changes in the prevalence of excess weight (overweight and obesity) and body composition of children living in different localities of La Plata district (Buenos Aires province, Argentina) over the last two decades. For this purpose, anthropometric data and information on the socioeconomic and environmental context of residence of schoolchildren aged 4.0-12.9 years collected during 2005-2009 (Cohort 1, n = 1 233) and 2016-2019 (Cohort 2, n = 1 499) were analysed and compared. From a secular perspective, the current analysis showed that the socioeconomic and environmental conditions of families living in La Plata district have deteriorated in recent decades. In this context, child excess weight increased by 13% and body composition was altered, mainly as a result of an increase in fat mass, without observing changes in the muscle component.
本研究的目的是增进对过去二十年里居住在拉普拉塔区（阿根廷布宜诺斯艾利斯省）不同地区儿童超重（超重和肥胖）患病率及身体成分长期变化的了解。为此，对2005 - 2009年（队列1，n = 1233）和2016 - 2019年（队列2，n = 1499）收集的4.0 - 12.9岁学童的人体测量数据以及其居住的社会经济和环境背景信息进行了分析和比较。从长期角度来看，当前分析表明，近几十年来居住在拉普拉塔区的家庭的社会经济和环境状况已经恶化。在此背景下，儿童超重率增加了13%，身体成分发生了改变，主要是由于脂肪量增加，而肌肉成分未观察到变化。
