Abstract:

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 Achilles 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.
