This article introduces a conjecture and reviews partial evidence about peculiarities in the aging of populations in Latin America and the Caribbean (LAC) that may impact future elderly health status. Using Survey on Health and Well-Being of Elders data (SABE; n = 10,902), the authors estimated effects of early childhood conditions on adult diabetes and heart disease. Using Waaler-type surfaces, the authors obtained expected mortality risks for SABE and also U.S. elderly (Health and Retirement System, n = 12,527). Expected mortality risks using Waaler-type surfaces among elderly in LAC reflected excesses supporting our conjecture. There was partial evidence of a relation between various indicators of early childhood nutritional status (knee height, waist-to-hip ratio) and diabetes and even stronger evidence of a relation between rheumatic fever and adult heart disease. There is some evidence, albeit weak, to suggest that the conjecture regarding elderly health status' connection to early conditions has some merit.

The article summarizes three of the data collection studies that can assist researchers in examining population aging processes in the Latin America and Caribbean region with an emphasis on cross-national comparisons, including the population of Mexican immigrants in the United States. These are the Survey on Health and Wellbeing of Elders conducted in seven urban centers of the region, the national Mexican Health and Aging Study, and the Hispanic Established Populations for Epidemiologic Studies of the Elderly in the United States. The article describes the studies and marks them as informative, comprehensive, and still underanalyzed in particular for the purpose of cross-national analyses of aging among Latin American and Caribbean populations.
