Longitudinal aging research in East and Southeast Asia: representativeness or depth?
Abstract
The systematic review by Malhotra and colleagues1 offers a comprehensive synthesis of community-based longitudinal aging studies across East and Southeast Asia (ESEA). Its timing is critical: with more than 30% of the world's older population residing in this region and aging accelerating faster than in most Western nations, the absence of robust longitudinal evidence is not merely a research gap but a policy failure in the making. Of the 30 eligible studies across 10 countries, 57% were concentrated in five high-income economies, while countries such as Indonesia, Cambodia, and Myanmar have none, a finding that reflects stark inequality in research capacity with direct implications for how widely ESEA-derived evidence can be safely generalized.
