To define the cognitive and physical attributes of regular social dancing so as to help establish its health benefits and help plan future dance interventions to prevent adverse outcomes in older adults such as falls, slow gait, and dementia.
Cross-sectional survey with two-group comparison.
Bronx County, New York.
Twenty-four cognitively normal older social dancers (OSDs) were compared with 84 age-, sex-, and education-matched older nondancers (ONDs) participating in a community-based study.
Motor and cognitive performance was assessed using validated clinical and quantitative methods.
There were no differences in the frequency of participation in other cognitive and physical leisure activities, chronic illnesses, or falls between OSDs and ONDs. Cognitive test performance was not different between OSDs and ONDs. OSDs had better balance but not strength than ONDs. OSDs had a longer mean stride+/-standard deviation than ONDs (117.8+/-10.5 cm vs 103.4+/-20.2 cm, P=.008) on quantitative gait assessment, with a more stable pattern during walking with reduced stance time (63.9% vs 65.9%, P=.01), longer swing time (36.1% vs 34.1%, P=.01), and shorter double support time (27.9% vs 30.9%, P=.03).
The results of this study suggest that long-term social dancing may be associated with better balance and gait in older adults.
定义定期社交舞蹈的认知和身体属性，以帮助确定其对健康的益处，并协助规划未来的舞蹈干预措施，以预防老年人出现跌倒、步态迟缓及痴呆等不良后果。
两组比较的横断面调查。
纽约布朗克斯县。
24名认知正常的老年社交舞者（OSD）与84名年龄、性别和教育程度相匹配的不跳舞的老年人（OND）参与了一项社区研究，并进行比较。
采用经过验证的临床和定量方法评估运动和认知表现。
在参与其他认知和身体休闲活动的频率、慢性病或跌倒方面，OSD和OND之间没有差异。OSD和OND在认知测试表现上没有差异。与OND相比，OSD的平衡能力更好，但力量并无差异。在定量步态评估中，OSD的平均步幅±标准差比OND长（117.8±10.5厘米对103.4±20.2厘米，P = 0.008），行走时模式更稳定，站立时间减少（63.9%对65.9%，P = 0.01），摆动时间更长（36.1%对34.1%，P = 0.01），双支撑时间更短（27.9%对30.9%，P = 0.03）。
本研究结果表明，长期社交舞蹈可能与老年人更好的平衡能力和步态有关。
