背景。在以中年人和非裔美国人为基础的人群研究中，对跌倒的恐惧和相关活动限制的普遍程度，以及它们与跌倒和跌倒疗效的联合分布，尚未得到充分的解决。非裔美国人健康项目是一项以人口为基础的小组研究，调查了998名出生于1936-1950年的非裔美国人，他们来自圣路易斯大都会的两个地区（一个贫困的内城地区和一个郊区）。在2000-2001年的家庭评估中，评估了跌倒恐惧、与恐惧相关的活动限制和24项与虚弱相关的协变量。我们发现，12.6%的参与者报告在没有活动限制的情况下害怕摔倒，13.2%的参与者在活动限制的情况下害怕摔倒，74.2%的参与者没有害怕摔倒。在三个出生队列（1946-1950、1941-1945和1936-1940）中，对跌倒的恐惧和与恐惧相关的活动限制都没有显著差异。这两种现象在过去2年内发生过跌倒和跌倒疗效低的患者中缺乏重叠是相当重要的。当对三组（无恐惧、无活动限制的恐惧和有活动限制的恐惧）进行检查时，显示出健康状况和社会、情感和身体功能下降的一致模式。在这个以人口为基础的样本中，49至65岁的非洲裔美国人，对摔倒的恐惧和与恐惧相关的活动限制令人惊讶地普遍，并且不能很好地解释以前的跌倒或低跌倒效果。这些现象在49-55岁时就已经很明显了。进一步的研究是有必要的，包括详细的定性调查，检查少数民族和多数人口中害怕摔倒和恐惧相关活动限制的时间、前体和后果。
Background. The prevalence of fear of falling and related activity restriction, and their joint distribution with falls and falls efficacy, have been inadequately addressed in population-based studies of middle-aged and African-American groups.Methods. The African American Health project is a population-based panel study of 998 African Americans born in 1936-1950 from two areas of metropolitan St. Louis (an impoverished inner-city area and a suburban area). Fear of falling, fear-related activity restriction, and 24 frailty-related covariates were assessed during in-home evaluations in 2000-2001.Results. We found that 12.6% of participants reported having fear of falling without activity restriction, 13.2% had fear of falling with activity restriction, and 74.2% had no fear of falling. Neither fear of falling nor fear-related activity restriction varied significantly across three birth cohorts (1946-1950, 1941-1945, and 1936-1940). Lack of overlap of these two phenomena with having a fall in the past 2 years and low falls efficacy was considerable. When examined across three groups (no fear, fear without activity restriction, and fear with activity restriction), a consistent pattern of decreasing health status and social, emotional, and physical functioning was demonstrated.Conclusions. in this population-based sample of 49- to 65-year-old African Americans, fear of falling and fear-related activity restriction were surprisingly common and not well explained by prior falls or low falls efficacy. These phenomena were already evident by age 49-55. Further study is warranted, including detailed qualitative investigations examining the timing, precursors, and consequences of fear of falling and fear-related activity restriction in minority and majority populations.
