Central adiposity in children has increased to a higher degree than general adiposity however it is not a routine measurement in clinical practice. We aimed to estimate the prevalence of overweight, obesity, and abdominal fat distribution and observe the prevalence of abdominal obesity among non-obese 6-10-year-old children.
Weight, height, and waist circumference were measured in a sample of 793 children (408 girls). International Obesity Task Force cut-offs were used to define overweight and obesity. Abdominal obesity was defined as waist-to-height ratio ≥ 0.50. Chi-square tests were used to observe the prevalence of the obesity indicators among boys and girls, and the relation between International Obesity Task Force cut-offs and abdominal obesity.
The prevalence of overweight, including obesity among children was 21.9% (18.9 - 25.0), 6.1% (4.2 - 8.0) were obese and 21.9% (18.6 - 25.0) had a waist-to-height ratio ≥ 0.50. Girls had significantly higher prevalence of overweight, including obesity compared to boys (χ2 = 4.59, p = 0.03), but no differences were found for abdominal obesity according to children's gender (χ2 = 3.32, p = 0.07). A proportion of normal (8.2%; 5.9 - 10.6) and overweight children (59.5%; 50.9 - 69.0) were abdominally obese.
The prevalence of general and abdominal obesity in children living in central Portugal is of concern. Many children with abdominal obesity would not be considered obese with the International Obesity Task Force cut-off points.
A high proportion of abdominal obesity was observed in children with normal weight or overweight, suggesting that waist-to-height ratio should be included in routine clinical practice and might be particularly useful to assess the health status of the child.
儿童中心性肥胖的增加程度高于总体肥胖，但在临床实践中它并非常规测量指标。我们旨在估计超重、肥胖和腹部脂肪分布的患病率，并观察6至10岁非肥胖儿童中腹部肥胖的患病率。
对793名儿童（408名女孩）的样本测量了体重、身高和腰围。采用国际肥胖特别工作组的临界值来定义超重和肥胖。腹部肥胖定义为腰高比≥0.50。使用卡方检验观察肥胖指标在男孩和女孩中的患病率，以及国际肥胖特别工作组临界值与腹部肥胖之间的关系。
儿童超重（包括肥胖）的患病率为21.9%（18.9 - 25.0），肥胖率为6.1%（4.2 - 8.0），腰高比≥0.50的比例为21.9%（18.6 - 25.0）。与男孩相比，女孩超重（包括肥胖）的患病率显著更高（χ2 = 4.59，p = 0.03），但根据儿童性别，腹部肥胖患病率未发现差异（χ2 = 3.32，p = 0.07）。一部分正常儿童（8.2%；5.9 - 10.6）和超重儿童（59.5%；50.9 - 69.0）存在腹部肥胖。
居住在葡萄牙中部的儿童中，总体肥胖和腹部肥胖的患病率令人担忧。许多腹部肥胖的儿童按照国际肥胖特别工作组的临界值不会被视为肥胖。
在体重正常或超重的儿童中观察到高比例的腹部肥胖，这表明腰高比应纳入常规临床实践，并且可能对评估儿童健康状况特别有用。
