UNASSIGNED: Because the rate of @entity604 is an important risk factor for @entity174 , we studied longitudinal changes in @entity79 ( @entity79 ). Although the @entity79 of the hip decreased over time, spine @entity79 remained largely stable or increased. Therefore, spine @entity79 may not be appropriate for assessing @entity79 change. INTRODUCTION: The rate of age-dependent @entity604 has been shown to be an important risk factor for @entity174 . However, longitudinal rates of @entity604 in Korea have not yet been reported. The objective of this study was to evaluate longitudinal changes in @entity79 in Korea. METHODS: This cohort study was performed in a population of individuals 40  years of age or older living in the rural area of Chungju City, Korea. A second @entity79 examination was conducted approximately 4  years after a baseline examination. A total of 3755 of the 6007 subjects completed the follow-up visit, corresponding to a follow-up rate of 62.51%. RESULTS: The age-standardized @entity170 prevalence was 12.81% in males and 44.35% in females. In males, the average annual @entity604 at the total hip increased from -0.25% per year in their 40s to -1.12% per year in their 80s. In females, the average annual @entity604 at the total hip increased from -0.69% per year in their 40s to -1.51% per year in their 80s. However, the average annual percentage change in spine @entity79 in females increased from -0.91% per year in their 40s to +1.39% per year in their 80s. CONCLUSIONS: A substantial number of subjects had @entity170 , even though we standardized the prevalence of @entity170 . In total hip, the mean @entity79 was decreased during the follow-up period; in addition, the annual percentage loss increased with age. However, spine @entity79 remained approximately stable or increased over time and therefore may not be appropriate for assessing @entity79 change.
