Somatic data were collected during April 1997 on 156 females ages 6, 9, 13, and 15 years, residing in urban Pusan, South Korea, and on 158 age peers residing in rural regions surrounding the city. Comparisons were made between urban and rural groups for measures of body size and form, skinfold thicknesses, the body mass index (BMI), and estimated arm muscle area (ARM). Age at menarche was retrospectively reported by the 13- and 15-year-olds. The data were analyzed in 2 (urban-rural) x 3 (age) analyses of variance with an alpha level of P < 0.05. Age differences were evident for all dimensions. A significant main effect for urban-rural differences was found for stature, lower limb height, upper limb height, shoulder width, hip width, triceps skinfold, ARM, skelic index, and the trunk width index. Regardless of age, urban children were larger than rural children. Similar means were obtained for the BMI in urban and rural girls. Age at menarche was consistent with recent results; however, the rural sample (12.4 years) was significantly earlier than the urban sample (13.1 years). Compared with data collected four decades ago, present-day 6-, 9-, 13-, and 15-year-old females are taller and heavier at every age, indicating secular gains. Pusan females are similar in stature to age peers in Taiwan, Japan, and Hong Kong, and taller than the Chinese. Am. J. Hum. Biol. 11:735-744, 1999. Copyright 1999 Wiley-Liss, Inc.
1997年4月收集了居住在韩国釜山市区156名6岁、9岁、13岁和15岁女性的身体数据，以及居住在该市周边农村地区的158名同龄人的身体数据。对城市和农村两组人群的身体大小和形态、皮褶厚度、体重指数（BMI）以及估计的手臂肌肉面积（ARM）进行了比较。13岁和15岁的女性回顾性报告了初潮年龄。数据采用2（城市 - 农村）×3（年龄）方差分析进行分析，显著性水平为P < 0.05。所有维度的年龄差异都很明显。在身高、下肢高度、上肢高度、肩宽、臀宽、肱三头肌皮褶、ARM、骨骼指数和躯干宽度指数方面发现了城市 - 农村差异的显著主效应。无论年龄如何，城市儿童都比农村儿童体型大。城市和农村女孩的BMI均值相似。初潮年龄与近期结果一致；然而，农村样本（12.4岁）明显早于城市样本（13.1岁）。与四十年前收集的数据相比，如今6岁、9岁、13岁和15岁的女性在每个年龄段都更高更重，表明存在长期增长趋势。釜山女性的身高与台湾、日本和香港的同龄人相似，比中国人高。《美国人类生物学杂志》11:735 - 744，1999年。版权所有1999年威利 - 利斯公司。
