【Abstract】 Objective To establish the peak bone density and analyze the possible lifestyle determinants. Methods A total of 386 healthy females aged 24-43 years were selected to participate in the bone mass detection by DEXA,and all subjects completed a questionnaire to obtain information on lifestyle. Results The peak bone density was seen in 38-39 year old group,and it seemed the same for different measurement sites.Meanwhile,body weight,milk consumption and occupation were identified as significant predictors of peak bone density. Conclusions Minimizing the intervals of age and establishing the standards for selecting subjects would minimize the standard deviation of peak bone density,which would be useful in improving the strategies for diagnosis of osteoporosis.更多还原
