Growth. 1983 Summer;47(2):207-16.
Anthropometric and dietary data were obtained on 78 rural and 66 urban Black girls age 9 years residing in eastern North Carolina. Direct measures were taken of standing height, sitting height, upper limb length, arm girth, calf girth, and body weight. Body form indices were derived for arm girth in percentage of upper limb length, calf girth in percentage of lower limb length, and lower limb length in percentage of sitting height. Intakes of protein and calories were estimated from 24-hour dietary recall protocols. Rural girls, on average, had shorter upper and lower limbs than urban girls. The Recommended Dietary Allowance (RDA) for protein intake was met by almost all subjects. More than 60% of both rural and urban girls were below the RDA for calorie intake, and about 40% below the RDA for vitamin A intake.
对居住在北卡罗来纳州东部的78名9岁农村黑人女孩和66名9岁城市黑人女孩进行了人体测量和饮食数据收集。直接测量了她们的身高、坐高、上肢长度、上臂围、小腿围和体重。计算了以下身体形态指数：上臂围占上肢长度的百分比、小腿围占下肢长度的百分比、下肢长度占坐高的百分比。通过24小时饮食回顾法估算蛋白质和热量摄入量。农村女孩的上肢和下肢平均比城市女孩短。几乎所有受试者的蛋白质摄入量都达到了推荐膳食摄入量（RDA）。超过60%的农村和城市女孩热量摄入量低于RDA，约40%的女孩维生素A摄入量低于RDA。
