In this study, author Frederick P. Thieme presents data on biological characteristics of the population of Puerto Rico. He includes data on nutrition, dental status, intestinal infestation, blood types, and more: data he gathered during fieldwork in 1948 and 1949. Thieme’s goals were to set up a baseline as a point of comparison; to study the relationship between physical variability and environment; and to pave the way for establishing medical standards for Puerto Rico.

In this study of lumbar breakdown (specifically spondylolisthesis and herniated intervertebral discs), Frederick P. Thieme finds that mechanical strains resulting from erect posture and lumbar curvature do contribute to low back breakdown in humans.
