This analysis aimed to determine the frequency of falls in men and women aged 50 years and over and to explore whether age variation in fall frequency may explain variation in the incidence of distal forearm fracture in women.
This was a cross sectional survey.
Primary care based registers in four UK areas.
Altogether 501 men and 702 women age 50-79 years participated.
A total of 131 (26.1%) men and 181 (25.8%) women reported falling in the previous year. In women, the frequency of falls rose with age (chi 2 test for trend 4.33; p = 0.04), with no obvious early post-menopausal peak or subsequent decline. Men aged 50-54 years had a significantly increased risk of falls compared with women of this same age group, (odds ratio (OR) = 2.4; 95% confidence interval (CI) 1.3, 4.6), though above this age, the risk of falling was greater in women (OR = 1.2; 95% CI 0.9, 1.5).
There are important differences in the frequency of falls in relation to age and sex. The data suggest that variation in fall frequency per se does not explain age variation in the incidence of distal forearm fracture in women.
本分析旨在确定50岁及以上男性和女性的跌倒频率，并探讨跌倒频率的年龄差异是否可以解释女性前臂远端骨折发病率的差异。
这是一项横断面调查。
英国四个地区基于初级保健的登记处。
共有501名年龄在50 - 79岁之间的男性和702名女性参与。
共有131名（26.1%）男性和181名（25.8%）女性报告在前一年有过跌倒。在女性中，跌倒频率随年龄增加（趋势的卡方检验为4.33；p = 0.04），绝经后早期没有明显的峰值或随后的下降。50 - 54岁的男性与同年龄组的女性相比，跌倒风险显著增加（优势比（OR）= 2.4；95%置信区间（CI）1.3，4.6），不过在这个年龄以上，女性的跌倒风险更大（OR = 1.2；95% CI 0.9，1.5）。
跌倒频率在年龄和性别方面存在重要差异。数据表明，跌倒频率本身的差异并不能解释女性前臂远端骨折发病率的年龄差异。
