Seven hundred and four women aged between 65 and 99 years (mean age 74.6 years), who were randomly selected from the community, took part in a study to determine whether health and lifestyle factors were associated with falls. In the 12 months before the survey, 66.1 per cent of the subjects experienced no falls, 19.7 per cent fell once and 14.2 per cent fell on two or more occasions. The proportion of women who fell outside the home decreased with age, with a corresponding increase in the proportion who fell inside the home on a level surface. The most common causes of falls reported were trips, slips and loss of balance. Some (27 per cent) suffered injuries as a result of a fall, and the proportion suffering injuries increased with age. Those who rated their health and balance as impaired, those with a limitation in activities of daily living, those receiving community services, those taking psychoactive drugs, and those taking four or more drugs had significantly more falls. On the other hand, those taking part in planned exercise and those active for seven or more hours per week had fewer falls. Smoking and alcohol consumption were not significantly associated with falls. Stepwise logistic regression analysis revealed poor vision, inactivity and subjective fall risk as variables that were independently and significantly associated with falling. These findings highlight possible intervention strategies for reducing falls risk in older people.
从社区中随机选取了704名年龄在65至99岁之间(平均年龄74.6岁)的女性参与一项研究,以确定健康和生活方式因素是否与跌倒有关。在调查前的12个月里,66.1%的受试者未发生跌倒,19.7%的受试者跌倒过一次,14.2%的受试者跌倒过两次或更多次。在家外跌倒的女性比例随年龄增长而下降,在家中平面上跌倒的女性比例相应增加。报告的跌倒最常见原因是绊倒、滑倒和失去平衡。一些人(27%)因跌倒而受伤,且受伤比例随年龄增长而增加。那些认为自己的健康和平衡受损的人、日常生活活动受限的人、接受社区服务的人、服用精神活性药物的人以及服用四种或更多药物的人跌倒次数明显更多。另一方面,参加有计划锻炼的人和每周活动7小时或更多的人跌倒次数较少。吸烟和饮酒与跌倒无显著关联。逐步逻辑回归分析显示,视力差、缺乏运动和主观跌倒风险是与跌倒独立且显著相关的变量。这些发现突出了降低老年人跌倒风险的可能干预策略。
