International research in development of 摘 osteoporosis has expanded rapidly. However there is limited information regarding 要 the evaluation of bone health for the elderly above 65 years old in Taiwan. (英) Therefore, the study recruited 125 group-living elderly from Yi-Yuan and Tsui-Po elderly accommodation institutions. A Hologic QDR-1500 dual-energy X-ray absorptometry was used to measure the bone mineral density (BMD) of the lumbar spine (LS) of subjects. Total daily physical activity (TDPA) was assessed by a nutrition screening questionnaire. Serum bone turnover markers, including bonespecific alkaline phosphatase (BAP), osteocalcin (OC), type I C-terminal propeptide (CICP) and pyridinoline (Pyd) were measured to assess the variable status of bone turnover in subjects. The average age of surveyed subjects was 79.1 ± 5.6 years. The average BMD at the LS of male and female elderly were 1.004 ± 0.191 g/cm2 and 0.833 ± 0.153 g/cm2, respectively. The prevalence of osteoporosis and osteopenia were 17.5% and 44.4% among male elderly and were 43.6% and 43.6% among female elderly respectively. The state of poor bone health was 61.9% in male elderly and 87.1% in female elderly. The mean concentrations of the BAP and Pyd in summer of the female elderly were 28.1% and 23.9% higher compared with adult reference values. The values of the BAP and Pyd of the male elderly were distributed within adult reference range. The mean concentration of OC in summer was increased in 83.1% of the male and 92.5% of the female elderly compared with reference values for adults. The mean concentration of CICP in summer was lower in 40.6% of the male and 25.4% of the female elderly, as compared with adult reference values. The mean value of bone turnover index for male and female elderly in winter was 2.4 times and 1.3 times than of the values in summer, respectively. The result indicated that bone turnover, as assessed by specific bone markers, was accelerated during winter in both sexes. The average TDPA of subjects was 26.8 ± 2.2 METs/day. The physical activity level ratio (TDPA/basal energy expenditure) of subjects was 1.39 ± 0.13. The degree of the positively correlation between BMD of the LS and awaken physical activity (APA) was enhanced after METs or kcal for the sleep was subtracted from TDPA. Moreover, we found that CICP and b-quotient increased with increasing TDPA (METs/day) in male elderly. We found decreased level of Pyd with increasing TDPA (METs/day) in male elderly. The state of bone health of most elderly was classified as osteopenia or osteoporosis. Our findings with respect to the differences in bone turnover markers between male and female elderly indicated that bone loss probably is a result of insufficient type I collagen synthesis in male elderly, whereas of excessive bone resorption in female elderly. Increase in physical activity may be positively correlated with type I collagen synthesis and negatively correlated with bone resorption.
