目的：本研究的目的是分析性别对跌倒发生的影响，并考虑合并症和体能差异。设计：这是一项针对 587 名 50 岁以上社区居民的横断面研究。分别通过问卷、生物阻抗和富勒顿电池评估跌倒、合并症（疾病和身体损伤的数量）和身体健康（身体成分、下半身和上半身的力量和柔韧性、敏捷性、有氧耐力和平衡性）。 结果：与男性相比，女性的跌倒发生率高 10%，疾病/损伤多 1.7 种，体脂多 10%，去脂体重少 26%，体能较差容量（P<0.05）。多变量逻辑回归显示，在调整合并症（OR，1.213；95% CI，1.109-1.328）、瘦体重（OR，0.958；95% CI，跌倒的主要危险因素为：脂肪量（OR，1.053；95% CI，1.021-1.086）和平衡性（OR，0.942；95% CI，0.914-0.971）。结论：女性更容易跌倒，可能是因为她们的健康状况和身体素质比男性差。然而，当合并症、瘦体重和脂肪体重以及平衡的数值相似时，男性表现出跌倒的可能性更高。在健康、身体成分和平衡良好的条件下，年龄并不是跌倒的重要危险因素。
Objective: The aim of this study was to analyze the contribution of sex to the occurrence of falls, accounting for comorbidities and differences in physical fitness.Design: This was a cross-sectional study of 587 community-dwelling adults who were older than 50 yrs. Falls, comorbidities (number of diseases and physical impairments), and physical fitness (body composition, lower and upper body strength and flexibility, agility, aerobic endurance, and balance) were evaluated via questionnaires, bioimpedance, and Fullerton batteries, respectively.Results: Compared with the men, the women presented a 10% higher fall prevalence, 1.7 more diseases/impairments, 10% more body fat, 26% less lean body mass, and poorer physical capacity (P < 0.05). Multivariate logistic regression revealed that male sex (odds ratio [OR], 2.723; 95% confidence interval [CI], 1.190-6.230) increased the likelihood of falling, after adjustment for comorbidities (OR, 1.213; 95% CI, 1.109-1.328), lean mass (OR, 0.958; 95% CI, 0.927-0.989), fat mass (OR, 1.053; 95% CI, 1.021-1.086), and balance (OR, 0.942; 95% CI, 0.914-0.971), which were the main risk factors of falls.Conclusions: Women are more susceptible to falling, presumably because they have poorer health and physical fitness than do men. However, when the values for comorbidities, lean and fat body mass, and balance were similar, the men demonstrated a higher probability of falling. Age is not a significant risk factor of falls under favorable conditions of health, body composition, and balance.
