The objective of the survey was to assess whether a secular trend still affected growth of the Czech child population and, if necessary, to update national growth standards. The study was designed in such a manner so that trends in child growth, obtained from comparisons of body height, body weight and head circumference from the two successive nation-wide representative surveys (1981, 1991) of the Czech child population, could be followed. Representative random samples of the Czech child population from 0 to 18 years of age were studied with the following number of examined subjects: 86,846 in 1991 and 117,643 in 1981. Nation-wide standards and growth charts for assessment of growth and development of both individuals and specific groups present main outcome of the survey. Statistically significant differences were found in body height (both sexes) and weight (more in boys). No highly significant differences were registered in head circumference. Based on newly assembled data growth charts for assessment of body height, proportionality and head circumference were designed. The findings of this study did not support the hypothesis that the secular trend in Czech child population has already ceased.
此次调查的目的是评估长期趋势是否仍在影响捷克儿童人口的生长发育，如有必要，则更新国家生长标准。该研究的设计方式是，通过对捷克儿童人口连续两次全国代表性调查（1981年、1991年）的身高、体重和头围进行比较，追踪儿童生长趋势。对捷克0至18岁儿童人口的代表性随机样本进行了研究，具体检查对象数量如下：1991年为86846人，1981年为117643人。评估个体和特定群体生长发育情况的全国标准及生长图表是本次调查的主要成果。研究发现身高（男女皆是）和体重（男孩更明显）存在统计学上的显著差异。头围方面未发现高度显著差异。基于新收集的数据，设计了用于评估身高、比例和头围的生长图表。本研究结果不支持捷克儿童人口长期趋势已经停止的假设。
