|Abstract:||Introduction: Body composition has been reported as a significant determinant of bone mineral density. However, data regarding the relationship between the body composition and quantitative ultrasound (QUS) are scarce. Methods: This cross-sectional study examined risk factors of reduced QUS measures in older men and women. A total of 699 subjects aged 60 years old and over-458 women and 241 men-who lived in rural communities of Thailand were randomly recruited. Results: By using broadband ultrasound attenuation at the cutoff point of mean -1.0 SD based on young Thai people, the independent factors associated with reduced QUS measures in men were: poor activity of daily living, older age, and low fat mass. As for older women, the independent factors were the number of years since menopause, lack of regular exercise, lower height, and low fat mass. When using the stiffness index at the cutoff point of mean -1.6 SD based on young Thai people, the independent factors associated with reduced QUS measures in men were older age and low fat mass. Meanwhile, the number of years since menopause and low lean body mass were independent risk factors in women. Conclusions: Poor activity of daily living in men or lack of regular exercise in women was found to be a modifiable risk factor of reduced QUS measures. Years since menopause and low lean body mass were significant factors determining reduced QUS measures in women. Fat mass was an independent factor associated with reduced QUS measures both in men and women. © International Osteoporosis Foundation and National Osteoporosis Foundation 2006.|
