Secular trend in body height since the Neolithic period

Abstract
The body height of children and adults is estimated on the basis of skeleton material from the middle Elbe-Saale region since the Neolithic period. The men's body height was calculated according to Breitinger (1938), the women's body height according to Bach (1965), and the children's body height according to Telkkä et al. (1962). These estimates are compared with the mean body height of living persons from the adult population and of Jena schoolchildren, respectively. These are the following essential results: 1. Since 7000 years ago changes of body height can be observed. There was an increase of the mean body height from the Neolithic period until the Bronce age. In the A.D. era no clear changes of the average values can be found until about the 12th century, after which there occurred decreases seen until the 19th century. 2. The greatest secular trends in children and adults arise in our century. 3. The influence of different environmental factors on the body height in past and present is discussed and the sex-specific reactions to changes of these environmental factors are described. 4. It is pointed out that social, and/or geographic influences can cause changes of the body height calculated from skeleton material.
