Relative foot size and shape to general body size in Javanese, Filipinas and Japanese with special reference to habitual footwear types

Stature, body weight, left foot length and breadth were measured on East Javanese, Filipinas in Northern Luzon, and Japanese in Tokyo. No footwear is used by the Javanese, rubber sandals are used by the Filipinas, and sneakers or leather shoes by the Japanese group. Regression lines regardless of age were obtained among these four measurements, body mass index (BMI), and relative foot breadth to foot length. The relationships between general body size and foot size/shape were examined with regard to footwear. The results can be summarized as follows: (1) in either sex, compared with the Japanese, the East Javanese have a longer foot for the same stature and body weight, and a wider foot for the same BMI and the same foot length; (2) the relationship between BMI and foot shape (breadth/length) is nearly the same in the Filipinas and the Japanese females, (3) sexual dimorphism of the foot is greater among the East Javanese than among the Japanese; (4) as body size/weight increases sexual dimorphism diminishes among the East Javanese, whereas it is more emphasized among the Japanese; (5) the appropriateness of the regression equation obtained from measurements of present-day barefoot peoples for estimation of the stature of prehistoric humans is supported.

Comparative foot dimensions in Filipino rural children and Tokyo children

The height, weight, chest circumference and foot size (length, breadth and circumference) were compared in Isabela (Philippines) and Tokyo (Japan) children in 1985. The Isabela subjects were 350 girls from 7 to 15 years of age, and 396 boys from 7 to 16 years of age. In Tokyo, the subjects were 191 girls and 186 boys, both from 7 to 18 years of age. The following results were obtained: (1) the Isabela children were significantly smaller in height and chest circumference, and lighter in weight than the Tokyo children; (2) there was no difference between Isabela and Tokyo children in foot breadth and circumference; (3) there was a protuberance of the first metatarso-phalanx joint in 4.5% of the Guibang village children in Isabela, but in none of the Tokyo children.
