The aim of this study was to show the validity of a new skinfold thickness for measuring nutritional status in children. We also compare submandibular skinfold thickness with other anthropometric measures and indices.
We have studied 899 boys and 837 girls between 3.0 and 15.1 years of age. All of them were healthy and from different socioeconomic statuses. We measured weight, height, obesity indices, circumferences, indices of body fat distribution and indices of body fat. Data were divided according to age and sex. We calculated the percentiles of submandibular skinfold thickness and correlations between this parameter and all other measurements were performed. The mean values of the two sexes were compared by using Student's t-test.
Submandibular skinfold is an easy and fast skinfold to measure. Its value is maximum at 10 and 11 years in girls and boys, respectively. This measurement is higher in girls than in boys at 5, 7, 10, 13 and 14 years of age (p < 0.05). There was a high correlation between this skinfold value and almost all of the measurements and indices studied, especially with the body mass index (r = 0.589), the sum of the four conventional skinfolds (r = 0.844), arm circumference (r = 0.513), arm fat area (r = 0.776) and percentage body fat (r = 0.830).
Submandibular skinfold thickness in children and adolescents shows a high correlation with body fat indices. It is for this reason that it could be used as a new measurement to assess nutritional status and obesity in children.
本研究旨在验证一种用于测量儿童营养状况的新型皮褶厚度的有效性。我们还将下颌下皮褶厚度与其他人体测量指标和指数进行比较。
我们研究了899名3.0至15.1岁的男孩和837名女孩。他们均健康且来自不同社会经济地位。我们测量了体重、身高、肥胖指数、周长、体脂分布指数和体脂指数。数据按年龄和性别进行划分。我们计算了下颌下皮褶厚度的百分位数，并对该参数与所有其他测量值之间进行相关性分析。使用学生t检验比较两性的平均值。
下颌下皮褶是一种易于测量且测量速度快的皮褶。其值在女孩和男孩中分别在10岁和11岁时达到最大值。在5、7、10、13和14岁时，女孩的这一测量值高于男孩（p < 0.05）。该皮褶值与几乎所有研究的测量值和指数之间存在高度相关性，尤其是与体重指数（r = 0.589）、四个传统皮褶之和（r = 0.844）、上臂围（r = 0.513）、上臂脂肪面积（r = 0.776）和体脂百分比（r = 0.830）。
儿童和青少年的下颌下皮褶厚度与体脂指数高度相关。因此，它可作为评估儿童营养状况和肥胖的一种新测量方法。
