Background COVID-19 social distancing policies resulted in reductions in community movement, however fall rates during this time have not been described. Methods This prospective study included adults ≥65 years old participating in the Ambulatory Blood Pressure in Older Adults (AMBROSIA) cohort and who completed ≥1 monthly falls calendar (August 2019-March 2021; n=250). Months were grouped to correspond to the fall 2020 phased re-opening (August-October) and the shelter-in-place policy during the winter 2020 surge (November-January) in Los Angeles, California and compared to the same months, one year earlier (i.e., before the pandemic). Results Participants had a mean (SD) age of 75.2 (6.1) years, 49.6% were White, and 53.2% were women. We obtained 2,795 falls calendars during follow-up. Overall, 110 (44.0%) participants reported a total of 421 falls (rate 15.1 per 100 calendar months). The highest monthly fall rate during the pandemic was 22.9 (95% CI 16.4-31.1) per 100 calendar-months in August 2020. The lowest fall rate during the pandemic was 8.6 (95% CI 3.5-17.8) per 100 calendar-months in February 2021. During the pandemic, fall rates in August, September, and October 2020 were higher than the previous year (rate ratio 1.8 [95% CI 1.1-2.9]) and fall rates in November and December 2020 and January 2021 were lower than the previous year (rate ratio 0.5 [95% CI 0.4-0.8]). Conclusions As the pandemic continues and older adults resume community mobility after a shelter-in-place period, providers should pay attention to the risk of falls.

COVID-19 大流行之前和期间的跌倒率变化：前瞻性 AMBROSIA 研究的结果


背景 COVID-19 社会疏远政策导致社区活动减少，但这段时间内的下降率尚未描述。方法 这项前瞻性研究纳入了参与老年人动态血压 (AMBROSIA) 队列的≥65 岁成年人，并且完成了≥1 个月的跌倒日历（2019 年 8 月至 2021 年 3 月；n=250）。对月份进行分组，以对应加利福尼亚州洛杉矶 2020 年秋季分阶段重新开放（8 月至 10 月）和 2020 年冬季高峰期间（11​​ 月至 1 月）的就地避难政策，并与同一月份、一年进行比较更早（即大流行之前）。结果 参与者的平均 (SD) 年龄为 75.2 (6.1) 岁，其中 49.6% 为白人，53.2% 为女性。我们在追踪过程中获得了 2,795 个秋季日历。总体而言，110 名 (44.0%) 参与者总共报告了 421 次跌倒（每 100 个日历月 15.1 次）。 2020 年 8 月，疫情期间最高月下降率为每 100 个日历月 22.9 例（95% CI 16.4-31.1）。2020 年 8 月，疫情期间最低下降率为每 100 个日历月 8.6 例（95% CI 3.5-17.8）。 2021年2月。疫情期间，2020年8月、9月和10月的下降率高于上年（比率1.8 [95% CI 1.1-2.9]），2020年11月、12月和2021年1月的下降率低于上年上一年（比率 0.5 [95% CI 0.4-0.8]）。结论 随着大流行的持续以及老年人在就地避难期后恢复社区活动，提供者应注意跌倒的风险。
