Cambodia experienced civil strife, political violence, severe food shortages, and lack of medical care during the rule of the Khmer Rouge in the 1970s. Many who died as a result were adult children or spouses of today’s older-aged population. The post–Khmer Rouge period was characterized by severe social dislocation and continuing conflict resulting in further losses of children and spouses. These have eroded the base of core family support in a country where formal channels of assistance are virtually absent. More recently, Cambodia has been experiencing the worst AIDS epidemic in Asia, resulting in the infection and death of adult sons and daughters of the current elderly population. This project collects and analyzes data from persons aged 60 and over in Cambodia on their current social, economic, and health status to assess the impact of the political turmoil of the last few decades on their support structures, health, and economic well-being; to examine the impact of the AIDS epidemic on their well-being; and to assess their knowledge and attitudes related to AIDS.
