■跌倒,更具体地说,跌倒相关的伤害,对医疗保健系统来说是昂贵的,并且可能损害一个人的自主权。
■研究久坐行为与跌倒相关损伤的影响,以及久坐行为的变化如何影响跌倒相关损伤的风险。
■从基线到第一次随访,来自加拿大老龄化纵向研究(CLSA)队列的横截面和纵向数据分析。
■CLSA数据来自43,558名45-85岁的加拿大人。
■在基线和随访时,久坐行为时间被归类为低(<1,080分钟/周),中等(1,080-1,440),或高(>1,440)。通过老年人身体活动量表(PASE)估算久坐行为。在后续行动中,根据参与者在时间点之间的分类变化,将参与者分为久坐行为增加或减少/无变化.
■久坐行为与跌倒相关伤害相关,与年龄无关,性别,慢性疾病的数量,和总体力活动水平OR(95CI)1.10(1.05-1.15)。相比之下,久坐行为的改变与跌倒相关损伤1.00(0.92-1.01)的风险无关.
■对于40至80岁的人来说,较高的久坐行为与跌倒有关。然而,久坐行为的短期变化不会影响与伤害相关的跌倒风险。尽管有结果,流行病学研究需要更精确地测量久坐行为,以便更好地捕捉随时间的变化。
UNASSIGNED: Falls, and more specifically, fall-related injuries, are costly to the healthcare system and can harm one\'s autonomy.
UNASSIGNED: To study the impact of sedentary behaviour associated with fall-related injuries and how a change in sedentary behaviour may impact the risk of a fall-related injury.
UNASSIGNED: From baseline to the first follow-up, cross-sectional and longitudinal data analysis from the Canadian Longitudinal Study of Aging (CLSA) cohort.
UNASSIGNED: CLSA data from 43,558 Canadians aged 45-85 were included in this study.
UNASSIGNED: At baseline and follow-up, sedentary behaviour time was categorized as low (<1,080 minutes/week), moderate (1,080-1,440), or high (>1,440). Sedentary behaviour was estimated via the Physical Activity Scale for the Elderly (PASE). At follow-up, participants were dichotomized as either increased or decreased/no change in sedentary behaviour according to their categorical change between time points.
UNASSIGNED: Sedentary behaviour was associated with fall-related injuries independently of age, sex, number of chronic conditions, and total physical activity levels OR (95%CI) 1.10 (1.05-1.15). In contrast, a change in sedentary behaviour was not associated with the risk of fall-related injury 1.00 (0.92-1.01).
UNASSIGNED: A higher level of sedentary behaviour is associated with injurious falls for people between 40 and 80 years old. However, a short-term change in sedentary behaviour does not influence the risk of injury-related falls. Despite the results, a more precise measure of sedentary behaviour is needed for epidemiology studies to capture changes over time better.
