研究还观察到，掌握额外语言能延缓衰老进程，并发现使用多语言存在剂量依赖效应（掌握语言越多， 延缓效果越显著）。他们指出，即使对年龄和语言、身体状况、社会和社会政治因素作调整后，多语言 的保护作用仍很显著。 鉴于此，推广使用多种语言可能在人群水平上有助于支持健康老龄化策略。这一发现可为促进老年群体 认知恢复及公共卫生政策提供更多帮助。 （文章来源：科技日报） 《自然·衰老》10日发表的论文称，科学家调查了27个欧洲国家超过86000人的信息，发现多语言能力 （日常使用超过一种语言）能延缓衰老速度。 衰老是一项重大的全球健康挑战，与认知衰退和功能障碍有关。过去的研究提出，使用多语言可能有助 于保护认知功能，但由于样本量较小、依赖临床队列和间接测量衰老指标等因素，相关证据并不一致。 位于爱尔兰的全球脑健康研究所团队分析了来自27个欧洲国家86149名51—90岁参与者的调查数据，评 估他们的衰老速度是否快于或慢于基于健康和生活方式因素的预期值。他们发现，仅使用一种语言的人 发生衰老加速的可能性会比预期值高约两倍，而多语言使用者的这一概率平均只有一半。 ...
