Abstract:
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.
