  •   Objective  To understand the level of radius speed of sound (SOS) in female college students and explore the effect of dietary on their bone health, so as to provide a reference for effective prevention fracture and osteoporosis among college students.  Methods  A total of 363 female college students were selected by multistage stratified random sampling method. Dietary intake was assessed with a self-administered food frequency questionnaire, principal component analysis was used to derive dietary patterns. Speed of sound was measured by ultrasonic bone densitometer.  Results  In all, the mean SOS of female college students was(4 138.0±114.3)m/s, 26.7% of female college students had low bone mass. Three dietary patterns were identified by factor analysis, explaining 55.4% of the diet variation: "snack" "plant" "high protein and high fat" patterns, respectively. Multiple linear regression analysis showed that with the increase of age, the level of SOS in radius increased significantly; and snacks consumption was negatively associated with the level of SOS(β=13.23, -0.47, P < 0.05).  Conclusion  University stage is still the critical period of bone mass accumulation for female, snacks consumption may have a negative impact on bone health, so it is necessary to carry out nutrition education to help improve health awareness, promote health eating, and lead health lives to prevent osteoporosis.
