There is little information on falls by sex and age strata in Japan, and few factors associated with falls have been established. However, the association between bone and joint diseases and falls remains unclear. We examined prevalence of falls by sex and age strata, determined its association with radiographic osteoarthritis (OA) of the knee and lumbar spine, and determined knee and lower back pain after single and multiple falls.
A questionnaire assessed the number of falls during 12 months preceding baseline. Knee and lumbar spine radiographs were read by Kellgren/Lawrence (K/L) grade; radiographic knee OA and lumbar spondylosis were defined as a K/L grade of 3 or 4. Knee and lower back pain were estimated by an interview.
A total of 587 men and 1,088 women (mean ± SD age 65.3 ± 12.0 years) were analyzed. During 1 year, 79 (13.5%) men and 207 (19.0%) women reported at least 1 fall. With increasing age, the prevalence of multiple falls was higher in women, but lower in elderly men age >60 years. In men, few factors were significantly associated with falls. In women, radiographic knee OA and lumbar spondylosis, as well as knee and lower back pain, were significantly associated with multiple falls without adjustment. Lower back pain and knee pain were independently associated with multiple falls in women after adjustment.
Lower back pain and knee pain were significantly associated with multiple falls in women.
日本有关性别和年龄层次的跌倒信息较少，与跌倒相关的因素也很少确定。然而，骨骼和关节疾病与跌倒之间的关系仍不清楚。我们检查了按性别和年龄层次划分的跌倒发生率，确定了其与膝关节和腰椎放射照相性骨关节炎（OA）的相关性，并确定了单次和多次跌倒后膝关节和下背部疼痛。
问卷调查评估了基线前 12 个月内跌倒的次数。膝关节和腰椎的 X 光片由 Kellgren/Lawrence（K/L）分级进行阅读；膝关节 OA 和腰椎病的放射照相定义为 K/L 分级 3 或 4。通过访谈估计膝关节和下背部疼痛。
共分析了 587 名男性和 1088 名女性（平均年龄 65.3 ± 12.0 岁）。在 1 年内，79 名（13.5%）男性和 207 名（19.0%）女性至少报告了 1 次跌倒。随着年龄的增长，女性多次跌倒的发生率较高，但 60 岁以上的老年男性较低。在男性中，很少有因素与跌倒显著相关。在女性中，放射照相性膝关节 OA 和腰椎病以及膝关节和下背部疼痛与未经调整的多次跌倒显著相关。在调整后，下背部疼痛和膝关节疼痛与女性的多次跌倒独立相关。
下背部疼痛和膝关节疼痛与女性的多次跌倒显著相关。
