背景资料：以前的研究表明，听力损失在老年人中非常普遍但治疗不足，可能与步态和身体功能有关。确定听力损失是否与步态速度独立相关，对于理解听力康复干预是否有助于缓解老年人身体功能的下降至关重要。方法：我们分析了1999年至2002年国家健康和营养检查调查周期的横断面数据，在此期间，50-69岁的参与者（n = 1180）进行了听力和步态速度评估。听力由听力较好的耳朵在0.5-4 kHz音调下听力阈值的纯音平均值定义。步态速度是在20英尺（6.1米）的定时步行中获得的。使用线性和逻辑回归模型来检查听力损失和步态速度之间的关联，同时调整人口统计学和心血管危险因素。分析纳入了抽样权重，以产生可推广到美国人口的结果。结果：在一个调整人口统计学和心血管危险因素的模型中，听力损失与较慢的步态速度相关（每25 dB听力损失-0.05 m/s [95% CI：-0.09至-0.02]），步态速度< 1.0 m/s的几率增加（OR = 2.0/25 dB听力损失，95% CI：1.2-3.3）。与25 dB听力损失相关的步态速度的减少相当于与年龄差约12 years.Conclusions：更大的听力损失与较慢的步态速度独立相关。需要进一步研究这种关联的机制基础以及听力康复干预是否会影响步态和身体功能。(C)2012年爱思唯尔B。V.保留所有权利。
Background: Previous studies have suggested that hearing loss, which is highly prevalent but undertreated in older adults, may be associated with gait and physical functioning. Determining if hearing loss is independently associated with gait speed is critical toward understanding whether hearing rehabilitative interventions could help mitigate declines in physical functioning in older adults.Methods: We analyzed cross-sectional data from the 1999 to 2002 cycles of the National Health and Nutritional Examination Survey during which participants 50-69 years (n = 1180) underwent hearing and gait speed assessments. Hearing was defined by a pure tone average of hearing thresholds at 0.5-4 kHz tones in the better-hearing ear. Gait speed was obtained in a timed 20-ft (6.1 m) walk. Linear and logistic regression models were used to examine the association between hearing loss and gait speed while adjusting for demographic and cardiovascular risk factors. Analyses incorporated sampling weights to yield results generalizable to the U.S. population.Results: In a model adjusted for demographic and cardiovascular risk factors, a hearing loss was associated with slower gait speed (-0.05 m/s per 25 dB of hearing loss [95% CI: -0.09 to -0.02]) and an increased odds of having a gait speed < 1.0 m/s (OR = 2.0 per 25 dB of hearing loss, 95% CI: 1.2-3.3). The reduction in gait speed associated with a 25 dB hearing loss was equivalent to that associated with an age difference of approximately 12 years.Conclusions: Greater hearing loss is independently associated with slower gait speed. Further studies investigating the mechanistic basis of this association and whether hearing rehabilitative interventions could affect gait and physical functioning are needed. (C) 2012 Elsevier B. V.
