尽管有证据表明肥胖从童年到青春期都很好,大部分研究是在西方和高收入国家进行的。此外,大多数研究都追踪了身体质量指数,作为营养状况的代表,而周长和皮褶厚度的跟踪特性研究较少。因此,这项研究的主要目的是探索从儿童到青少年的完整人体测量数据的追踪特征。
本子研究是捷克ELSPAC研究的一部分。在目前为期8年的纵向研究中,我们从8岁(n=888)的儿科医生的医疗记录中收集信息,11y(n=1065),13y(n=811)和15y(n=974),包括周长(头部,胸部,腰部,臀部,andarm),指数(身体质量指数,腰臀比和腰高比)和皮褶厚度(二头肌,三头肌,肩胛骨下,suprailiaca,大腿和5个皮肤褶皱的总和)。参与者是从捷克共和国的两个选定地区(布尔诺和兹诺伊莫)招募的。进行线性广义估计方程,以分析8年随访期间所有人体测量的跟踪模式。
跟踪系数中等到强,周长范围从0.40到0.62,指数为0.41至0.74,皮褶为0.72至0.86。根据体重指数和腰围标准,超重/肥胖儿童和8岁时腹型肥胖儿童分别为11.31(95%CI=8.41~15.22,p<0.001)和10.73(95%CI=7.93~14.52,p<0.001),更有可能在15岁时保持超重/肥胖和腹型肥胖。即周长适度地跟踪,同时观察到指数和皮褶厚度的强跟踪。此外,对8岁至15岁之间的一般超重/肥胖和腹部肥胖进行强有力的追踪表明,应该提倡在小学开始时检测这些危险因素。
Although evidence suggests that obesity track well from childhood to adolescence, most of the research has been done in Western and high-income countries. Moreover, most of the studies have tracked body-mass index, as a proxy of nutritional status, while tracking characteristics of circumferences and skinfold thicknesses have been less studies. Therefore, the main purpose of the study was to explore tracking characteristics of complete anthropometric data from childhood to adolescence.
This sub-
study was part of the Czech ELSPAC
study. In the present 8-year longitudinal
study, we collected information from pediatrician\'s medical records at the ages of 8 y (n = 888), 11 y (n = 1065), 13 y (n = 811) and 15 y (n = 974), including circumferences (head, chest, waist, hips, and arm),
indices (body-mass index, waist-to-hip ratio and waist-to-height ratio) and skinfold thicknesses (biceps, triceps, subscapula, suprailiaca, thigh and the sum of 5 skinfolds). Participants were recruited from the two selected regions of the Czech Republic (Brno and Znojmo). Linear generalized estimating equations were conducted to analyze tracking patterns over an 8-year follow-up period for all anthropometric measurements.
Tracking coefficients were moderate to strong, ranging from 0.40 to 0.62 for circumferences, 0.41 to 0.74 for
indices and 0.72 to 0.86 for skinfolds. According to body-mass index and waist circumference standards, overweight/obese children and children with abdominal obesity at the age of 8 y were 11.31 (95% CI = 8.41 to 15.22, p < 0.001) and 10.73 (95% CI = 7.93 to 14.52, p < 0.001) more likely to remain overweight/obese and to have abdominal obesity at the age of 15 y.
Findings show moderate to strong tracking of anthropometric characteristics, i.e. circumferences track moderately well, while strong tracking for
indices and skinfold thicknesses is observed. Moreover, strong tracking of general overweight/obesity and abdominal obesity between ages 8 y and 15 y indicates that the detection of these risk factors at the beginning of primary school should be advocated.
