While community health workers (CHWs) are being implemented in several developing countries, there has been little work done to evaluate their effectiveness in reducing childhood malnutrition among participating communities. Our study evaluates the effectiveness of CHWs in three Guatemalan villages by comparing anthropomorphic measures and mortality rates of children under five before and after the implementation of a CHW program. While one community showed no significant change in malnutrition rates in terms of height-for-age calculations, two other communities showed improved malnutrition rates in terms of height-for-age. Weight-for-age comparisons were not statistically significant, and while childhood mortality remained unchanged in one community, there was a 5% improvement in childhood mortality for the other communities combined.
