Using as example the secular trend, relations between growth, maturation and environment are discussed. This phenomenon is characterized by an increase of the average height and an acceleration of growth velocity and maturation. The increase is acquired mainly in the early childhood. The secular trend has been modified by local and socio-economic differences in the frequency of malnutrition and morbidity. It is now minimal in countries with high standards of health and hygiene. It can appear or can be accelerated in all developing countries with progress in child-health, especially in early childhood. A negative trend can be expected in every country, where child-health deteriorates for a long time.
以长期趋势为例，讨论了生长、成熟与环境之间的关系。这种现象的特征是平均身高增加以及生长速度和成熟加速。这种增加主要在幼儿期获得。长期趋势因营养不良和发病率的地区及社会经济差异而有所改变。在卫生和健康标准较高的国家，这种趋势目前最小。在儿童健康取得进步的所有发展中国家，尤其是在幼儿期，这种趋势可能会出现或加速。在儿童健康长期恶化的每个国家，预计会出现负面趋势。
