A sample of 761 subjects 70 years and over was drawn from general-practice records of a rural township. Each subject was assessed and followed for 1 year to determine the incidence of and factors related to falls. The fall rate (number of falls per 100 person-years) increased from 47 for those aged 70-74 years to 121 for those 80 years and over. There was no sex difference in fall rate but men were more likely than women to fall outside and at greater levels of activity. Twenty per cent of falls were associated with trips and slips but we found no evidence that inspection of homes and installation of safety features would have decreased the fall rate. Ten per cent of falls resulted in significant injury. Men who fell had an increased subsequent risk of death compared with those who did not fall (relative risk 3.2, 95% CI 1.7-6.0). Subsequent mortality was increased among women who fell but not to significant levels (relative risk 1.6, 95% CI 0.9-2.7).
从一个乡村小镇的全科医疗记录中抽取了761名70岁及以上的受试者样本。对每个受试者进行评估并随访1年,以确定跌倒的发生率及相关因素。跌倒率(每100人年的跌倒次数)从70 - 74岁人群的47次增加到80岁及以上人群的121次。跌倒率没有性别差异,但男性比女性更有可能在户外及活动程度较高时跌倒。20%的跌倒与绊倒和滑倒有关,但我们没有发现证据表明检查房屋和安装安全设施会降低跌倒率。10%的跌倒导致了严重伤害。跌倒的男性与未跌倒的男性相比,随后死亡风险增加(相对风险3.2,95%置信区间1.7 - 6.0)。跌倒的女性随后死亡率增加,但未达到显著水平(相对风险1.6,95%置信区间0.9 - 2.7)。
