Anthropometric data of Chilean male workers

The aim of this study was to update the Chilean male workers’ anthropometric database to be used for design purposes and to examine the secular changes observed in a group of anthropometric variables for Chilean male workers. Data collection involved a sample of 2,346 male workers with ages ranging from 18 to 65+, assigned to the Mutual de Seguridad C.Ch.C in the two most populated regions of Chile (Valparaíso and Metropolitana) distributed in nine economic activities branches. Data collection was performed by two teams of 3 physiotherapies each. Before starting the collection process, the measurement teams underwent a training session of one week that included a theoretical session on the basic concepts of anthropometrics, as well as some practical instructions. A total of 32 anthropometric measures were gathered following the ISO standard 7250-1. Before applying the data, a checking process was carried out, trying to identify errors related to the data collection process. The magnitude of the positive secular trend for the stature was 1.0 cm per decade and the highest value was found for shoulder breadth, with a positive increase of 2.7 cm per decade. The results obtained allowed to observe the existence of a positive secular trend for most of the selected body measurements. Finally, it was also possible to verify that the current research may be used for design purposes and to establish the baseline data for long-term observation regarding anthropometric changes among Chilean male workers.
