本文对110对7～12岁同性别双生儿童的体重、体块指数、Rohrer指数和皮脂厚度等体脂肪指标的研究结果表明:正常小学儿童体脂肪的变异主要受遗传因素影响,遗传度为0.62～0.83;遗传与环境因素对不同部位皮脂厚度的影响程度不同,躯干脂肪主要受遗传因素影响,四肢脂肪主要受环境因素影响。
The body weight, body mass index, Rohrer index and sebum thickness of 110 twins of 7-12-year-old twins, such as body fat index results show that: normal primary school children body fat variation mainly due to genetic factors, the heritability of 0.62 ~ 0.83. The influence of genetic and environmental factors on the sebum thickness in different parts was different. Torso fat was mainly affected by genetic factors, and limb fat was mainly affected by environmental factors.
