目的：研究听力敏锐度是否与行走能力相关，基线听力受损是否预示3年后新的自我报告的行走困难。设计：前瞻性随访。设置：研究实验室和社区。参与者：434名年龄在63至76岁的妇女。测量：听力采用临床测听法测量。一个人被定义为有听力障碍，如果纯音平均阈值在0.5至4千赫在较好的耳朵是21分贝或更大。最大步行速度测量为10 m（m/s）以上，步行耐力测量为距离（m），6 min内完成，2 km步行困难根据自我报告。基线时，听力障碍女性（n = 179）的最大步行速度较慢（1.7 +/- 0.3 m/s vs 1.8 +/- 0.3 m/s，P = .007），步行耐力较低（520 +/- 75 m vs 536 +/- 75 m，P = 0.08），并且与无听力障碍的患者相比，自我报告的行走2 km的主要困难更多（12.8% vs 5.5%，P= 0.02）。在随访期间，33名参与者出现了严重的行走困难。基线时听力受损的妇女有两倍的年龄调整后的风险为新的行走困难的那些没有听力障碍（优势比= 2.04，95%置信区间= 0.96-4.33）。结论：听力与流动性，这可能是解释听力受损和平衡不良和更大的风险之间的关联福尔斯，这两者的基础下降的流动性。预防听力损失不仅对交流能力很重要，而且可能对功能能力产生更广泛的影响。J Am Gerlatr Soc 57：2282-2286，2009.
OBJECTIVES: To examine whether hearing acuity correlates with walking ability and whether impaired hearing at baseline predicts new self-reported walking difficulties after 3 years.DESIGN: Prospective follow-up.SETTING: Research laboratory and community.PARTICIPANTS: Four hundred thirty-four women aged 63 to 76.MEASUREMENTS: Hearing was measured using clinical audiometry. A person was defined as having a hearing impairment if a pure-tone average of thresholds at 0.5 to 4 kHz in the better ear was 21 dB or greater. Maximal walking speed was measured over 10 m (m/s), walking endurance as the distance (m), covered in 6 minutes and difficulties in walking 2 km according to self-report.RESULTS: At baseline, women with hearing impairment (n = 179) had slower maximal walking speed (1.7 +/- 0.3 m/s vs 1.8 +/- 0.3 m/s, P = .007), lower walking endurance (520 +/- 75 m vs 536 +/- 75 m, P =.08), and more selfreported major difficulties in walking 2 km (12.8% vs 5.5%, P= .02) than those without hearing impairment. During follow-up, major walking difficulties developed for 33 participants. Women with hearing impairment at baseline had a twice the age-adjusted risk for new walking difficulties as those without hearing impairment (odds ratio = 2.04, 95% confidence interval = 0.96-4.33).CONCLUSION: Hearing acuity correlated with mobility, which may be explained by the association between impaired hearing and poor balance and greater risk for falls, both of which underlie decline in mobility. Prevention of hearing loss Is not only important for the ability to communicate, but may also have more wide-ranging influences on functional ability. J Am Gerlatr Soc 57:2282-2286, 2009.
