概括

生物行为年龄差距 (BAG) 揭示了差异如何加速衰老,特别是在低收入地区. 该框架确定了可修改的因素,以减轻全球老龄化不平等,并为公共政策提供信息.

科学领域:

  • 老年学与公共卫生
  • 生物统计学和机器学习在衰老研究中的应用.

背景情况:

  • 健康老龄化受到保护性和风险因素的复杂相互作用的影响,差异加剧了这些影响,特别是在高度不平等的地区.
  • 社会经济和多式联运暴露差异对衰老轨迹的累积影响,包括延迟和加速衰老,仍然不够理解.
  • 本研究介绍了生物行为年龄差距 (BAG) 作为一种新的框架,用于量化保护性和风险因素的联合影响,以差异和暴露量为调制.

研究的目的:

  • 引入和验证生物行为年龄差距 (BAGs) 框架,用于测量保护性和风险因素对衰老的综合影响.
  • 评估社会经济和环境差异 (暴露体) 如何调节衰老轨迹.
  • 提供一个具有成本效益和生态有效的工具,用于公共政策和能力建设在代表性不足的地区.

主要方法:

  • 机器学习被用于估计BAG,使用来自40个国家的161,981名参与者的数据,并结合了国家调查数据.
  • 分析了保护因素 (认知,功能,教育) 和风险因素 (心脏代谢状况,女性性别,感官障碍).
  • 分析检查了跨地区,收入水平和物理,社会和社会政治暴露的BAG,通过各种统计措施进行验证.

主要成果:

  • BAGs准确地预测了时间的年龄,与延迟衰老相关的保护因素和加速衰老的风险因素.
  • 与欧洲和亚洲相比,加速衰老在非洲和拉丁美洲更为普遍,在低收入国家和高收入国家更为普遍.
