贵阳地区体育与非体育专业大学生超声跟骨骨强度比较研究

Comparison study of ultrasound calcaneus strength index of physical and non-physical college students in Guiyang

目的探讨贵阳地区体育与非体育专业大学生跟骨骨强度的差异,为骨质疏松的防治提供科学依据。方法采用定量超声的检测技术,测量了贵阳地区3所高校中体育专业199名,非体育专业173名大学生的跟骨骨强度指数及T值等指标,并进行问卷调查。结果①无论男女个体,体育专业学生的跟骨骨强度指数及T值均高于非体育专业,差异有统计学意义(P<0.01)。②无论体育与非体育专业,跟骨骨强度指数和T值都有随着运动频率增加而增加的趋势(P<0.01)。③跟骨骨强度指数和T值有随着饮奶频率增加而增加的趋势(P<0.05)。结论运动及饮奶有助于骨质强度的增加,贵阳地区大学生运动及牛奶饮用情况均不理想。

Objective Discuss the difference of calcaneus strength index of physical and non-physical college students, to provide scientific basis for the prevention and control of osteoporosis. Methods Using the Quantitative Ultrasound, we measured calcaneus strength index and T-score of 199 physical students and 173 nonphysical students in 3 colleges of Guiyang, and we also executed questionnaires. Results （ 1 ） Regardless of the gender, calcaneus strength index and T-score of physical students are all higher than that of non-physical students＇, the differences were significant（ P 〈 0.01 ）. （2）Among both physical and non-physical students, there was a tendency that the increase of calcaneus strength index and T-score went with the increase of exercise frequency, the differences were significant（ P 〈 0.01 ）. （3）There was a tendency that the increase of calcaneus strength index and T-score went with the increase of drinking milk frequency （ P 〈 0.05）. Conclusions Exercises and drinking milk were good for the increase of bone strength, the exercises and drinking milk condition of Guiyang college students were not ideal.
