The prevalence of weight disorders among school-aged children is an increasing phenomenon and it is of great importance to identify the characteristics of individuals at risk of gaining or retaining weight. This study aimed to examine the prevalence of weight disorders and their tracking over a 3-year period in a sample of Italian children. Body mass, body height and selected skinfold thicknesses were assessed in 355 children at the age of 7 and 10 years. Tracking of body mass index (BMI), inverted BMI (iBMI) and skinfold-based body fat were analyzed and the relationships between changes in BMI and body fat were examined. Children presenting with overweight or obesity at 7 years old showed a trend toward lower weight categories at 10 years old. Conversely, a trend to become overweight was observed among normal weight boys, and a trend to become underweight was observed among normal weight girls. BMI, iBMI and body fat showed good levels of tracking, with high correlations between measurements performed at 7 and 10 years of age. Furthermore, BMI and iBMI changes were correlated to body fatness changes. The present study shows the importance of carefully following children's development over time because weight disorders may appear even in previously normal weight children.
学龄儿童体重障碍的患病率呈上升趋势，因此识别体重增加或保持风险的个体特征非常重要。本研究旨在研究意大利儿童样本中，3 年内体重障碍的患病率及其变化情况。在 355 名 7 岁和 10 岁儿童中，评估了体重、身高和选定的皮褶厚度。分析了体重指数（BMI）、反转 BMI（iBMI）和基于皮褶的体脂的追踪情况，并检查了 BMI 变化与体脂之间的关系。7 岁时超重或肥胖的儿童在 10 岁时体重呈下降趋势。相反，在正常体重的男孩中观察到超重的趋势，而在正常体重的女孩中观察到体重不足的趋势。BMI、iBMI 和体脂具有较好的追踪水平，7 岁和 10 岁测量之间的相关性很高。此外，BMI 和 iBMI 的变化与体脂的变化相关。本研究表明，随着时间的推移，仔细跟踪儿童的发育非常重要，因为体重障碍甚至可能出现在以前体重正常的儿童中。
