The aim of this study was to investigate the anthropometric parameters and body impedance once per year during four years of the pubertal period in Estonian children. In total, 81 boys and 86 girls aged 10-11 years at the beginning of the study were investigated. Pubertal status was self-assessed by sexual maturation stages according to Tanner and physical activity index (PAI) according to Telama et al.. Body height and weight were measured and body mass index (BMI) calculated. In total, 9 skinfolds, 13 girths, 8 lengths and 8 breadths/lengths were measured according to the protocol of the International Society for the Advancement of Kinanthropometry. Somatotype components were estimated according to the method of Carter and Heath. Body impedance was measured using Multiscan 5000 (Bodystat, UK) and the impedance index (height/impedance) was calculated. The tracking of body height, weight, BMI, skinfolds, girths, lengths, breadth/lengths and body impedance was high (as a rule r> or =0.9). By increasing the time period, the correlation slightly decreased. In contrast, tracking correlations for PAI and Tanner stages were significant but quite low. Increase in mean body height was highest between 12-13 years of age (6.9 cm per year) in boys and in girls between 11-12 years of age (6.3 cm per year). In boys and girls, the peak increase in body weight was between 11 and 12 years of age, 5.7 kg and 5.2 kg, respectively. With the increasing age, body impedance decreased and impedance index increased. In conclusion, our results indicate that during puberty the detailed anthropometric parameters and body impedance tracked highly. However, the tracking of PAI and Tanner stages was significant but relatively low.
本研究的目的是在爱沙尼亚儿童青春期的四年中，每年对其人体测量参数和身体阻抗进行一次调查。研究开始时，共对81名男孩和86名年龄在10至11岁的女孩进行了调查。青春期状态通过根据坦纳（Tanner）的性成熟阶段进行自我评估，并根据特拉马（Telama）等人的方法评估身体活动指数（PAI）。测量身高和体重，并计算体重指数（BMI）。根据国际人体测量学促进协会的方案，总共测量了9个皮褶厚度、13个围度、8个长度和8个宽度/长度。根据卡特（Carter）和希思（Heath）的方法估算体型成分。使用Multiscan 5000（英国Bodystat公司）测量身体阻抗，并计算阻抗指数（身高/阻抗）。身高、体重、BMI、皮褶厚度、围度、长度、宽度/长度和身体阻抗的追踪相关性很高（通常r≥0.9）。随着时间周期的增加，相关性略有下降。相比之下，PAI和坦纳阶段的追踪相关性显著但相当低。男孩平均身高增长最高的年龄段是12至13岁（每年6.9厘米），女孩是11至12岁（每年6.3厘米）。男孩和女孩体重增加的峰值均在11至12岁之间，分别为5.7千克和5.2千克。随着年龄的增长，身体阻抗下降，阻抗指数增加。总之，我们的结果表明，在青春期，详细的人体测量参数和身体阻抗追踪相关性很高。然而，PAI和坦纳阶段的追踪相关性显著但相对较低。
