STUDY DESIGN: A cross-sectional and prospective study of @entity3604 . OBJECTIVES: To investigate the correlation between @entity455 or history of @entity65 , back function, @entity170 , and @entity174 . BACKGROUND: It has been postulated that @entity731 may compromise blood flow to bone and soft tissues in the back, causing @entity158 and disability. Recent studies have presented conflicting results. METHODS: At baseline, information on back @entity158 and function, general functional status, cardiovascular history, and general lifestyle variables was obtained from 1492 elderly white @entity1 (mean age, 71 years) enrolled in the Study of @entity3604 . Lateral radiographs of the lumbar and thoracic spine were obtained, and @entity455 was assessed. Follow-up information was obtained an average of 3.7 years later. RESULTS: At baseline, 82 @entity1 had @entity455 , 443 had a history of @entity65 , and 277 had @entity174 ; 58 @entity1 had one or more additional @entity174 during the follow-up period. After adjustment for age, @entity1 with @entity65 were more likely to have back @entity158 and disability as a result of the back @entity158 than @entity1 free of @entity65 ; at the follow-up examination, the back-related disability was more than twice as likely to have worsened in the @entity65 group. No correlation was found between @entity455 . Neither the prevalence of @entity174 at baseline, nor the incidence of @entity174 was associated with the presence of @entity455 or @entity65 . CONCLUSIONS: Results indicated that back problems in elderly @entity1 are associated with self-reported @entity65 , but not with objectively assessed @entity455 .
