BACKGROUND AND AIMS: @entity209 and @entity170 are recognized as major public health problems in many countries. This study investigated the association between bone quality and components of @entity209 in an elderly population. METHODS: The study included a population sample of 211 @entity1 and @entity1 , of mean age 77.9    4.5 years. Anthropometry, blood pressure, serum levels of lipoproteins (HDL and LDL), @entity1674 and @entity413 were measured, and ultrasound bone densitometry was performed in all subjects. Information on lifestyle habits, including physical activity, smoking and @entity167 consumption, were obtained by a questionnaire. RESULTS: @entity209 , defined by the criteria of the International @entity6 Federation, was determined in 59% of @entity1 and 65% of @entity1 . The quantitative ultrasound index (QUI) was significantly correlated with serum @entity413 in @entity1 (r=-0.31; p=0.005) and with body mass index (BMI) in @entity1 (r=0.39; p<0.0001). QUI was significantly lower in @entity1 with @entity209 (F=7.57; p<0.007) and significantly higher in @entity1 with it (F=6.47; p=0.012) compared with controls. When QUI was adjusted for body mass index in @entity1 and for serum @entity413 in @entity1 , it was no longer significantly different from values for controls. Other covariates such as @entity165 , blood pressure, smoking, @entity167 , and physical activity did not change the difference in QUI between @entity1 with @entity209 and controls. @entity6 in @entity1 (p=0.005) and @entity28 and waist circumference in @entity1 (p<0.05) were also significant predictors of QUI in regression analysis. CONCLUSIONS: The association between @entity209 and bone stiffness in elderly @entity1 may be explained by increased BMI in @entity1 and high serum @entity413 in @entity1 .
