Relationship between bone mass and lifestyle were investigated in 117 Chinese students in Japan and 162 Japanese students. They were measured speed of sound, transmission index and osteo sono-assesment index (OSI) at the calcaneus by using quantitative ultrasound AOS-100 (ALOKA Co., Ltd, Tokyo), and 42 of them were also measured bone mineral density (BMD) by dual-energy X-ray absorptionmetry (DXA). Height, weight and grip strength were measured, and percent of body fat was assessed by bioelectronic impedance method. We asked current physical activities and food intakes by the questionnaire. The questionnaire also included items to ask histories of diet and physical activities. Nutrient intakes were calculated by using the food frequency questionnaire (Yoshimura, 2001). The following results were obtained 1) OSI was significantly correlated with BMD measured by DXA. 2) OSI adjusted body weight of Chinese female students in Japan were equivalent to Japanese female students and there was no difference between OSIs of Chinese male students in Japan and Japanese male students. 3) OSI of Chinese female students in Japan were correlated with current calcium intake, milk/dairy products intake or bean/bean products intake in the past. 4) OSI of Chinese female students in Japan were correlated with their past physical activity.
