To estimate the prevalence of falls in elderly individuals and to analyze associated factors.
Cross-sectional study with 420 elderly subjects (aged 60 years or older) living in the city of Juiz de Fora (Southeastern Brazil) in 2010. A household survey was conducted and the occurrence of falls in the 12 previous months was described. For the analysis of factors associated with the outcome, a theoretical determination model with three hierarchical blocks was built. The variables were adjusted among each other within each block; those with level of significance < 0.20 were included in the Poisson regression model and adjusted to the immediately higher level, with 5% significance level.
The prevalence of falls among the elderly was 32.1% (95%CI: 27.7; 36.9). Among those who experienced falls, 53% had a single fall and 19% had fractures as a consequence. Most of the falls (59%) occurred at the elderly person's home. The occurrence of falls was associated with old age, female sex, need of help for locomotion and self-reported diagnosis of osteoporosis.
Falls are frequent among the elderly. Knowledge of the factors associated with the occurrence of this event can aid the development of prevention strategies and adequate health services.
评估老年人跌倒的发生率，并分析相关因素。
2010 年，对巴西东南部城市茹伊斯-迪福拉（Juiz de Fora）的 420 名 60 岁及以上老年人进行了一项横断面研究。进行了一次家庭调查，并描述了在过去 12 个月中发生跌倒的情况。为了分析与结果相关的因素，建立了一个具有三个层次块的理论确定模型。在每个块内对变量进行相互调整；那些显著性水平<0.20 的变量被纳入泊松回归模型，并调整到更高的水平，显著性水平为 5%。
老年人跌倒的发生率为 32.1%（95%CI：27.7；36.9）。在跌倒的老年人中，53%有单次跌倒，19%有骨折后果。大多数跌倒（59%）发生在老年人的家中。跌倒的发生与年龄较大、女性、行动需要帮助和自我报告的骨质疏松症诊断有关。
老年人跌倒很常见。了解与该事件发生相关的因素有助于制定预防策略和提供适当的卫生服务。
