Description:Objectives:
This research evaluated measurement errors (ME) of anthropometric devices and measurers (Study I) and anthropometric changes of law enforcement officers (LEO) in 4 decades via a preliminary investigation (Study II), to determine the need for a national LEO anthropometry survey.
Background:
Managing measurer-and-equipment ME and defining the necessities of a survey are critical steps for conducting a successful national anthropometry study.
Method:
In Study I, 480 datasets (5 measurers × 6 manikins × 16 body dimensions) were recorded, using anthropometric calipers and tapes, two full-body three-dimensional scanners, and a wireless digital tape. In Study II, 32 body dimensions of 67 regional male LEOs were measured and the data were compared to the best available LEO anthropometry data from 1975 and two recent non-LEO national anthropometry databases.
Results:
Study I showed that MEs of our measurers/equipment were largely within acceptable ranges, and the measurements were generally compatible among traditional caliper/tape, scanner, and digital tape methods. Study II showed that anthropometric dimensions were significantly different between this LEO study and existing data sources.
Conclusion:
The results validated that the MEs of measurers/equipment were within acceptable limits. The study confirmed that the existing 45-year-old LEO dataset and recent Army and civilian datasets would not be adequate for armor and equipment design for the current LEO population.
Application:
The study results are useful for supporting a decision on investing in a national LEO anthropometry survey and for equipment manufacturers to be aware of the distinctiveness of LEO anthropometry and measurement errors.
