Investigating the trends and causes of changes in human anthropometric dimensions over the past three decades: a challenge for ergonomic design.

Objectives. The present study aimed to review the changes in anthropometric dimensions around the world during the last 30 years. Methods. The search for this study was conducted in four databases with related keywords. Papers from 1990 to 2021 were reviewed and 4139 articles were identified, with 505 related titles. Of these, 187 articles met the eligibility criteria, and their whole text was examined; 132 articles were then included for the final review. Results. The reviewed studies showed that a large number of anthropometric dimensions of the human body have become larger than in the past, such as height. Although the increasing trend of anthropometric dimensions in the past has been faster than in recent years, decreasing changes have also been seen in some anthropometric dimensions, such as the human jaw, face width and head width. It should be noted that the main reasons for the changes mentioned in the studies are economics and family income, social conditions, health and nutrition. Conclusion. Since the process of changes in anthropometric dimensions is not always the same, anthropometric data should be updated regularly, and work environments and equipment should be reviewed or redesigned according to the new anthropometric data.
