This study describes gender differences in the level and pattern of physical activity in groups of older adults who were frequent fallers, intermittent fallers, or non-fallers.
Interviews were conducted with adults aged 50 years and older (N=1834) at senior centers across Pennsylvania from 2010 to 2011. Self-reported falls and validated measures of physical activity were collected at baseline and at 6- and 12-month follow-up assessments.
Complete follow-up data were available for 1487 participants. Men who fell frequently decreased in recreational/leisure activity and household/yard work compared to the intermittent fallers and non-fallers. This association remained even when controlling for baseline health status. All women-regardless of fall group-engaged in similar levels of recreational/leisure activity and household/yard work over time. For both men and women, frequent fallers also showed a greater decrease in walking activities compared to intermittent fallers and non-fallers.
Frequent falling among older adults is associated with declines in common leisure, household, and walking activities. The effect of falling frequency on physical activity appears to affect men and women differently, generating the hypothesis that interventions to promote physical activity among fallers need to be gender specific.
本研究描述了经常跌倒者、间歇性跌倒者或非跌倒者这几组老年人身体活动水平和模式的性别差异。
2010年至2011年期间，在宾夕法尼亚州各地的老年中心对50岁及以上的成年人（N = 1834）进行了访谈。在基线以及6个月和12个月的随访评估中收集了自我报告的跌倒情况和经过验证的身体活动测量数据。
1487名参与者有完整的随访数据。与间歇性跌倒者和非跌倒者相比，经常跌倒的男性在娱乐/休闲活动以及家务/庭院工作方面有所减少。即使在控制了基线健康状况后，这种关联仍然存在。随着时间的推移，所有女性——无论属于哪个跌倒组——参与的娱乐/休闲活动和家务/庭院工作水平相似。对于男性和女性而言，与间歇性跌倒者和非跌倒者相比，经常跌倒者在步行活动方面的减少也更大。
老年人经常跌倒与常见的休闲、家务和步行活动减少有关。跌倒频率对身体活动的影响似乎对男性和女性的影响不同，由此产生了一个假设，即促进跌倒者身体活动的干预措施需要针对不同性别。
