Disparities exist between Latinos and non-Latino Whites in cognitive function. Dance is culturally appropriate and challenges individuals physically and cognitively, yet the impact of regular dancing on cognitive function in older Latinos has not been examined. A two-group pilot trial was employed among inactive, older Latinos. Participants (N = 57) participated in the BAILAMOS dance program or a health education program. Cognitive test scores were converted to z-scores and measures of global cognition and specific domains (executive function, episodic memory, working memory) were derived. Results revealed a group × time interaction for episodic memory (p < .05), such that the dance group showed greater improvement in episodic memory than the health education group. A main effect for time for global cognition (p < .05) was also demonstrated, with participants in both groups improving. Structured Latin dance programs can positively influence episodic memory, and participation in structured programs may improve overall cognition among older Latinos.
拉丁裔与非拉丁裔白人在认知功能方面存在差异。舞蹈在文化上是合适的，并且对个人的身体和认知能力都有挑战，然而，定期跳舞对老年拉丁裔认知功能的影响尚未得到研究。我们在不活跃的老年拉丁裔人群中进行了一项两组试点试验。参与者（N = 57）参加了BAILAMOS舞蹈项目或健康教育项目。认知测试分数被转换为z分数，并得出整体认知和特定领域（执行功能、情景记忆、工作记忆）的测量结果。结果显示，情景记忆存在组×时间交互作用（p <.05），即舞蹈组在情景记忆方面的改善比健康教育组更大。还证明了整体认知的时间主效应（p <.05），两组参与者都有改善。结构化的拉丁舞项目可以对情景记忆产生积极影响，参与结构化项目可能会改善老年拉丁裔的整体认知。
