The aim was to assess the effects of genetic factors and environmental influences on adolescence body height.
The study was a retrospective survey of mean standing height collected from computerised medical draft records of 17-18 year old adolescents, born between 1950 and 1971.
All the studied population is resident of the state of Israel.
About half a million records of recruits were examined. The sex distribution was: 61% male, 39% female. Ethnic distribution of the studied population was according to the countries of origin: Poland 7.8%, Romania 22.0%, Yemen 11.4%, Iraq 17.5%, Morocco 27.4%, and Israel 7.8%.
Marked differences in standing height measures were found between the ethnic groups compared to the Israeli reference group. A linear increase of 1.1 mm/year for reference males and 0.8 mm/year for the female population was found over the 22 years of study period. Ethnic groups with lower mean height were found to have a significantly greater increase in height during the period studied.
Israel as an immigration country may serve as a model for the study of environmental and genetic factors. Under conditions found in Israel, body height continues to increase with year of birth, while significant differences in height between ethnic groups has diminished.
旨在评估遗传因素和环境影响对青少年身高的作用。
本研究是一项回顾性调查，收集了1950年至1971年出生的17 - 18岁青少年的计算机化医学档案记录中的平均身高数据。
所有研究对象均为以色列居民。
检查了约50万份新兵记录。性别分布为：男性61%，女性39%。研究人群的种族分布依据原籍国划分：波兰7.8%，罗马尼亚22.0%，也门11.4%，伊拉克17.5%，摩洛哥27.4%，以色列7.8%。
与以色列参照组相比，各民族在身高测量上存在显著差异。在22年的研究期间，参照组男性身高每年线性增长1.1毫米，女性每年增长0.8毫米。研究发现，平均身高较低的民族在研究期间身高增长幅度显著更大。
以色列作为一个移民国家，可作为研究环境和遗传因素的范例。在以色列的条件下，身高随出生年份持续增长，而各民族之间的身高显著差异已有所减小。
