Objective. To identify validated information available on the relationship between social capital (SC) and health in Latin America and the Caribbean (LAC). Methods. A systematic search for papers published from January 1990-June 2007 was conducted on the Medline, SciELO, LILACS, and the Cochrane Library databases. All of the research and review articles published by scientific journals that evaluated CS and its relationship to health in LAC were included in the analysis. Results. Fifteen articles were found (11 original research and 4 reviews). The health topics examined by the research articles were: (a) mortality and life expectancy, (b) mental health, (c) injuries, (d) nutritional status, and (e) immunization. The validity of these works, the results, and the principal conclusions were analyzed in depth. Conclusions. Despite limitations inherent to the CS concept and the studies identified, it was confirmed that scientific evidence exists to support the possible association between CS and health in LAC. CS could play a protective role in certain health areas, such as injury prevention and mental health; not withstanding, the relationship between CS and health could vary according to CS subtype and socioeconomic context and culture. It is therefore imperative to continue social epidemiology research that thoroughly investigates the relationship between social determinants and specific aspects of health in LAC context.

The establishment of environmental health indicators for assessing the adverse effects of environmental changes on the population's health and quality of life is, as yet, a goal that has not been fully reached in Latin America and the Caribbean. As such, the United Nations Environment Program and the Pan American Health Organization (PAHO) have convened Region's institutions and experts to develop a comprehensive method for assessing environmental health. This paper evaluates several methodologies, comprehensive or otherwise, for assessing health and the environment, and describes the frameworks that have historically undergirded the key methods that have either structured or generated the environmental health indicators being used in Latin America and the Caribbean. The recurring, methodological limitations were identified: (a) relying heavily on secondary data, which points out the need for technological infrastructure that is rarely available in Latin America and the Caribbean today; and (b) a lack of clear criteria for developing inclusive tools that would facilitate the discussion of environmental health issues at the grass-roots level. Despite the progress made by the field of environmental health with regard to understanding its interdisciplinary complexities, intersectoral operations must be improved to favor open communication and implementation of integrated policies on environmental and health.
