The aim of this paper was, therefore, to present the cross-sectional data on the body composition profiles of rural primary school children in Tshannda, South Africa.
A cross-sectional study was carried out to examine the body composition among 409 Tshannda rural school children, grade 1-7 levels, in Vhembe district of Limpopo province, South Africa. The anthropometric variable measured included, body mass, stature, arm circumference, triceps, biceps, subscapular and supraspinale. Derived indicators were sum of skinfold thickness, body mass index (BMI), mid-upper arm circumference, percentage body fat, fat mass and fat-free mass, which were used to determine body composition.
A significant difference in the sum of skinfold thickness was noticed between boys and girls. The girls have higher skinfold thickness than boys at all ages. The percentage of body fat was higher in girls than boys.
The high proportion of body fat among rural South African school children, especially girls, warrants an action strategy to prevent and control overweight and obesity in this age group.
因此,本文的目的是呈现南非尚达农村小学儿童身体成分概况的横断面数据。
在南非林波波省韦姆贝区开展了一项横断面研究,以调查409名尚达农村小学1至7年级学生的身体成分。测量的人体测量变量包括体重、身高、上臂围、肱三头肌、肱二头肌、肩胛下和脊柱上。派生指标有皮褶厚度总和、体重指数(BMI)、上臂中部围度、体脂百分比、脂肪量和去脂体重,这些指标用于确定身体成分。
注意到男孩和女孩在皮褶厚度总和上存在显著差异。各年龄段女孩的皮褶厚度均高于男孩。女孩的体脂百分比高于男孩。
南非农村学童,尤其是女孩,体脂比例较高,这就需要制定一项行动策略来预防和控制该年龄组的超重和肥胖问题。
