The book examines the health rights of older persons who are more likely potentially to face various disadvantages in terms of healthcare access and affordability, thereby impacting on health outcomes. The point of departure in the analyses is that the health security of older persons is guaranteed only if a country approaches the health of its citizens out of moral obligation, viewing health and well-being as a right rather than an entitlement. Data from five countries in the ASEAN region are analysed with the intent of highlighting the health inequalities and barriers at the societal and individual levels, on the one hand, as well as the gaps at the health and healthcare policy and programmatic levels within each country, on the other. It is also intended that the analyses of the data from the selected countries which represent different stages of development, and thus income levels, provide a useful comparative framework for policymakers in the ASEAN region.
