汉、壮、瑶、苗、侗5个民族在校大学生的骨密度比较研究

摘要

Objective To understand the status and differences of bone mineral density in multi-ethnic college students in Guangxi,to improve the bone mineral density of multi-ethnic college students and to provide theoretical basis for the prevention of osteoporosis.Methods A total of 2726 college students were randomly selected.These college students were from Han,Zhuang and other ethnic groups (including Yao,Miao,and Dong).The right calcaneal bone density was measured by quantitate heel ultrasound.Data including bone mass index,T-score and Z-score were obtained.Results There were no ethnic differences in bone mass index,T-score and Z-score of male college students (P ＞ 0.05).There were ethnic differences (P ＜ 0.05) in bone mass index of female college students,and the bone mass index significantly different between Han and Zhuang groups and between Han and Yao groups (P ＜ 0.05).However,there were no ethnic differences in T-and Z-scores among female students (P ＞ 0.05).Conclusion The differences of bone mineral density level in multi-ethnic college students were not significant;however there were ethnic differences in bone mass index of female college students.It is suggested that college students should strengthen their exercise,balance their diet and increase their calcium intake,so as to improve their bone health.%目的 了解广西多民族在校大学生的骨密度现状及其差异性,为提高多民族在校大学生骨密度水平和预防骨质疏松提供理论依据.方法 随机抽取广西某高校汉族、壮族、瑶族、苗族及侗族共2726名在校大学生,采用超声骨密度仪测量右跟骨骨密度,包括骨质指数、T值和Z值.结果 男性在校大学生的骨质指数、T值及Z值民族间差异均无统计学意义(P＞0.05);女性在校大学生的骨质指数民族间差异有统计学意义(P＜0.05),其中汉壮、汉瑶女大学生组间的骨质指数差异有统计学意义(P＜0.05),而女大学生的T值和Z值民族间差异均无统计学意义(P＞0.05).结论 广西多民族在校大学生的骨密度水平差异无统计学意义,仅有在校女大学生的骨质指数存在民族差异.建议在校大学生应加强锻炼、均衡饮食和补充钙类食物的摄入,提高骨质健康.
