Bone density and body composition on the pacific rim: A comparison between japan‐born and u.s.‐born japanese‐American women

摘要: Bone mineral density (BMD) of total body, spine, and proximal femur the percentage body fat in 151 U.S.-born Japanese-American women 137 Japan-born immigrant living San Diego, California were measured using dual-energy x-ray absorptiometry. These data compared with unpublished from Japanese obtained previous studies Hamamatsu, Japan.
