A cross-sectional study of age, physical size and body composition at menarche was made at Ilorin, Nigeria among 162 secondary school girls who reached menarche between March and June, 1983. The findings show that the mean age, height and weight are 13.7 +/- 1.0 years, 156.2 +/- 6.3 cm and 47.4 +/- 6.7 kg, respectively. The estimated body composition is: total body water (TBW), 25.7 +/- 2.3 l; lean body mass (LBM), 35.7 +/- 3.3 kg; and fat content, 11.8 +/- 3.8 kg. Whereas the coefficient of variation was highest for fat content (32.2), it was least for height (4.0). Menarcheal age has a weak correlation to all the variables, but strong correlation existed between weight and the parameters of body composition. The findings of body composition at menarche in Nigerian and North American schoolgirls are similar.
1983年3月至6月期间,在尼日利亚伊洛林,对162名初潮少女进行了一项关于初潮时年龄、身体尺寸和身体成分的横断面研究。研究结果显示,平均年龄、身高和体重分别为13.7±1.0岁、156.2±6.3厘米和47.4±6.7千克。估计的身体成分如下:总体水(TBW)为25.7±2.3升;瘦体重(LBM)为35.7±3.3千克;脂肪含量为11.8±3.8千克。脂肪含量的变异系数最高(32.2),而身高的变异系数最低(4.0)。初潮年龄与所有变量的相关性较弱,但体重与身体成分参数之间存在较强的相关性。尼日利亚和北美女学生初潮时的身体成分研究结果相似。
