Objective: To compare physical characteristics, health and fitness-related variables, and nutrient intake between children of Japanese ancestry living in the United States and Japan.Design: Cross-sectional study.Setting: Miami, Fla, and Tsukuba, Japan.Subjects: Fourteen children of Japanese descent living in the United States and 14 sex-and age-matched children living in Japan.Main Outcome Measures: US and Japanese resident groups were compared on physical characteristics, health and fitness-related variables, and nutrient intake using the t test for paired samples. To assess differences between groups in variables not statistically significant, effect sizes were calculated using the Cohen d test of standardized differences.
Results:The following significant differences were found between US and Japanese resident groups, respectively: body mass index, 19. Conclusions: A small sample (n=14) of children of Japanese descent living in Florida showed more adverse healthrelated characteristics than did a comparable group of their peers living in Japan. The results are probably related to differences in their diets. It remains to be seen whether the differences in diets are related to where the children live.
