Multimorbidity is widely recognized as having adverse effects on health and wellbeing and may threaten the ability of older adults to live independently. Much of what is known about multimorbidity rests on research that has largely focused on one point in time, or from a static perspective. Given that there remains a lack of agreement in the field on how to standardize multimorbidity definitions and measurement, it is not surprising that analyzing and predicting multimorbidity development, progression over time, and its impact are still largely unaddressed. As a result, there are important gaps and challenges to measuring and studying multimorbidity in a longitudinal context. This Research Practice perspective summarizes pressing challenges and offers practical steps to move the field forward.

追踪不同种族/族裔人群随时间推移的多发病率变化：问题和考虑因素。

多种疾病被广泛认为对健康和福祉有不利影响，并可能威胁老年人独立生活的能力。关于多重发病率的许多已知信息都主要基于某个时间点或从静态角度进行的研究。鉴于该领域在如何标准化多发病率定义和测量方面尚未达成共识，因此分析和预测多发病率的发展，随着时间的发展及其影响仍未得到解决，这不足为奇。结果，在纵向环境下测量和研究多发病率存在重大的差距和挑战。该研究实践观点总结了紧迫的挑战，并提供了推动该领域前进的实际步骤。
