The effects of new vertebral fracture to activities of daily living among community-dwelling middle aged and elderly women

我们纵向研究了居住在社区的日本妇女新发椎骨骨折及其与日常生活活动和背痛的关系。受试者为330名42岁的女性，平均随访时间为3.3（范围：2.0-4.4）年。获得侧位胸部和腰椎X线片。测量前、中、后高度。新发椎体骨折定义为后续X线片上一维至少减少20%。采用自填式问卷调查参与者的日常生活活动（ADL），背部疼痛和背部相关的残疾。33.2%的患者发生新发椎体骨折（年风险为10.1%）。在调整了年龄因素后，在“弯腰或捡起一个轻物体”和“将物体举过头顶”的情况下，发现了两处或两处以上骨折与无骨折的临界关联。29.7%的新骨折女性和22.3%的无骨折女性背痛加重。多发性新发椎体骨折与背痛增加相关（p=0.08）。在背痛增加的妇女中，69%的骨折妇女和80%的无骨折妇女去看医生。

We studied new vertebral fractures and its associations with activities of daily living and back pain longitudinally among community-dwelling Japanese women. The subjects were 330 women aged 42 years old, and the mean duration of follow up was 3.3 (range ; 2.0-4.4) years. Lateral thoracic and lumbar radiographs were obtained. The anterior, medial, and posterior heights were measured. A new vertebral fracture was defined as a decrease of at least 20% in 1 dimension on subsequent films. A self-administered questionnaire was used to survey participants about activities of daily living (ADL), back pain and back-related disability. New vertebral fractures occurred in 33.2% (annual risk, 10.1%). After adjusting for age, borderline association of two or more fractures compared with no fracture was found in 'bending over or picking up a lightweight object' and 'reaching an object above your head'. The 29.7% of women with new fractures and 22.3% of women without fracture increased back pain. Multiple new vertebral fractures associated with increased back pain (p=0.08). Among women with increased back pain, 69% of women with fractures and 80% of women without fracture visited physician.
