云南红河地区哈尼族体质量、体质量指数与跟骨超声速度

背景：国外学者报道人群骨量20%归于环境因素,80%归于遗传因素,骨密度的种族及民族差异是很明显的.目的：调查云南红河地区哈尼族跟骨定量超声测量,分析其与体质量及体质量指数之间关系.方法：采取随机整群抽样和调查者入户调查的方式对云南省红河地区哈尼族人群300名进行抽样调查,其中男109名,女性191名.现场访谈填写调查表并测量血压、身高、腰围、体质量等,同时均用Achil es Express跟骨定量超声测量仪测量被调查者的右侧跟骨超声速度,并进行相关性分析.结果与结论：被调查的人群体质量平均为（46.39±8.44） kg,体质量指数平均为（21.07±3.21） kg/m2跟骨定量超声传导速度值为（1512.38±36.77） m/s.相关分析显示,右跟骨定量传导速度值与跟骨密度T值相关性高,可以预测跟骨骨密度.跟骨定量超声传导速度值除与年龄呈负相关,与体质量及体质量指数均呈正相关,并均有显著性意义.提示云南省红河地区哈尼族中老年人的跟骨骨密度与体质量及体质量指数有显著的相关关系.

Association between calcaneal ultrasound speed and body mass and body mass index among the Hani minority from the Red River region, Yunnan Province

BACKGROUND： Foreign scholars have reported 20% bone mass attributed to environmental factors, and 80% attributed to genetic factors. The racial and ethnic differences in bone mineral density are obvious. OBJECTIVE： To investigate calcaneal quantitative ultrasound measurements of the Hani population from the Red River region of Yunnan Province, and to analyze the correlation of calcaneal quantitative ultrasound measurements with body mass and body mass index. METHODS： A random cluster sampling survey and household survey were applied in 300 respondents of Hani nationality who lived in the Red River region, Yunnan Province, China. The respondents included 109 males and 191 females. The questionnaire was completed via on-site interviews, and blood pressure, height, waist circumference, and body mass of the respondents were measured. At the same time, the speeds of sound in the right calcaneus of the respondents were measured using the GE Achil es Express？ ultrasonometer. Correlation analysis was performed. RESULTS AND CONCLUSION： The average body weight was （46.39±8.44） kg, body mass index was （21.07±3.21） kg/m2 , and the speed of sound was （1512.38±36.77） m/s. Correlation analysis showed that the speed of calcaneal quantitative ultrasound in the right calcaneus was highly correlated with bone mineral density T values, demonstrating that the speed of sound could predict bone density of the calcaneus. The speed of calcaneal quantitative ultrasound was negatively correlated with age, but positively correlated with body mass and body mass index. These findings indicate that the elderly of Hani nationality from the Red River region in Yunnan Province present a significant correlation of calcaneal bone density to body mass and body mass index.
