Falls are a common occurrence in elderly persons, including relatively healthy, community-dwelling men and women. A significant percentage of falls result in soft-tissue injuries. Although some risk factors for falls have been identified, more research is needed on risk factors for injurious falls. In addition, there is little information from prospective studies on the long-term consequences of falls other than injury.
Risk factors and consequences of falls were analyzed in a 24-month prospective study of 482 elderly (mean age 74 +/- 6.7 years) men and women living independently.in the community. Falls and injurious falls were ascertained by telephone and by a bimonthly postcard follow-up. Predictor variables were obtained from a baseline assessment and follow-up questionnaire. Outcomes were defined as rates of falls and injurious falls, circumstances surrounding the fall, and the long-term correlates of falls.
Sixty-one percent of the participants (53.7% of men and 65.7% of women) reported one or more falls during the 2-year follow-up. The crude rates of injurious falls were 11.17 per 1000 person-months in women and 7.23 per 1000 person-months in men. Age, history of fracture, low physical health, and low or high mobility level were risk factors for injurious falls in both sexes. The inability to balance unsupported on one leg was associated with injurious falls in women (rate ratio [RR] = 3.0; 95% confidence interval 1.9-4.7). Self-reported cognitive, physical health, and mobility impairments were greater in female fallers compared to the nonfallers.
Falls and injurious falls without fracture are frequent events for healthy elderly people and may be associated with morbid changes in cognitive status, physical health, and mobility.
跌倒在老年人中很常见,包括相对健康、居住在社区的男性和女性。相当一部分跌倒会导致软组织损伤。尽管已经确定了一些跌倒的风险因素,但对于致伤性跌倒的风险因素仍需要更多研究。此外,除了受伤之外,前瞻性研究中关于跌倒长期后果的信息很少。
在一项为期24个月的前瞻性研究中,对482名独立生活在社区中的老年人(平均年龄74±6.7岁)的跌倒风险因素和后果进行了分析。通过电话和每两个月寄一次明信片进行随访来确定跌倒和致伤性跌倒情况。预测变量来自基线评估和随访问卷。结果定义为跌倒和致伤性跌倒的发生率、跌倒时的情况以及跌倒的长期相关因素。
61%的参与者(男性为53.7%,女性为65.7%)在2年随访期间报告发生了一次或多次跌倒。女性致伤性跌倒的粗发生率为每1000人月11.17次,男性为每1000人月7.23次。年龄、骨折史、身体健康状况差以及活动能力低或高是男女致伤性跌倒的风险因素。女性单腿无支撑时无法保持平衡与致伤性跌倒相关(率比[RR]=3.0;95%置信区间1.9 - 4.7)。与未跌倒者相比,女性跌倒者自我报告的认知、身体健康和活动能力受损情况更严重。
对于健康的老年人来说,跌倒和无骨折的致伤性跌倒很常见,并且可能与认知状态、身体健康和活动能力的病态变化有关。
