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

我们研究了日本社区妇女中新发椎体骨折及其与日常生活活动和背痛的纵向关系。研究对象为330名女性，年龄42岁，平均随访时间3.3年（范围2.0 ~ 4.4年）。获得胸椎和腰椎侧位x线片。测量前、中、后高度。新的椎体骨折被定义为在随后的片子中1维下降至少20%。采用自填问卷对参与者进行日常生活活动（ADL）、背部疼痛和背部相关残疾的调查。新的椎体骨折发生率为33.2%（年风险为10.1%）。在对年龄进行调整后，与没有骨折相比，在“弯腰或拿起轻物体”和“够到头顶上方的物体”中发现了两处或更多骨折的边缘关联。29.7%的新骨折女性和22.3%的未骨折女性背部疼痛加重。多发椎体骨折与背部疼痛增加相关（p=0.08）。在背痛加重的女性中，69%有骨折的女性和80%没有骨折的女性去看医生。

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.
