Concerns about falling (CAF) affect daily life activities in older people; however, it is unclear whether gender moderates this relationship. The authors investigated the cross-sectional relationship between CAF and objectively measured physical activity (PA) and gait quality in 503 community-dwelling older men and women. About 448 people (age = 76.2 [SD 7.9] years, 296 females) contributed sufficient data on movement intensity, activity duration (bouts of walking, sitting, and standing), number of transitions between activities (sit-to-stand and sit-to-walk), number of steps and gait quality, quantified as walking speed, and sample entropy. Associations with the Iconographical Falls Efficacy Scale were tested. The authors found no significant moderation by gender. However, women participated in less PA than men and showed a more irregular walking pattern. Higher levels of CAF led to lower PA and poorer gait quality. Our findings suggest that prevention of CAF-related PA avoidance may be particularly important for women, who are less active and at higher risk of falls.
对跌倒的担忧（CAF）会影响老年人的日常生活活动；然而，尚不清楚性别是否会调节这种关系。作者调查了503名社区居住的老年男性和女性中CAF与客观测量的身体活动（PA）和步态质量之间的横断面关系。约448人（年龄=76.2[标准差7.9]岁，女性296名）提供了关于运动强度、活动持续时间（步行、坐着和站立的时长）、活动之间的转换次数（从坐到站和从坐到走）、步数以及步态质量（以步行速度和样本熵量化）的充分数据。测试了与图像化跌倒效能量表的关联。作者发现不存在显著的性别调节作用。然而，女性的身体活动比男性少，且行走模式更不规律。较高水平的CAF会导致较低的身体活动和较差的步态质量。我们的研究结果表明，预防与CAF相关的身体活动回避对女性可能尤为重要，因为女性活动较少且跌倒风险较高。
