Social Epidemiology faculty member, Estaban Calvo, just published a review and analysis of aging policy in Argentina, Chile, Costa Rica, and Mexico. The article in the Journal of Aging and Social Policy describes how initial charity-based approaches to poverty and illness were gradually replaced by a rights-based approach considering broader notions of well-being, and that recent policy reforms emphasize the need for national, intersectoral, and evidence-based policy. The results of this review have implications for identifying priorities for intervention and informing policy reforms in developing countries worldwide.
