Conditional cash transfer (CCT) programs link public transfers to human capital investment in hopes of alleviating current poverty and reducing its intergenerational transmission. Whereas nearly all studies of their impacts have focused on youth, these CCT programs may also have an impact on aging adults, by increasing household resources or inducing changes in allocations of time of various household members, that may be of substantial interest, particularly given the rapid aging of most populations. This paper contributes to this under-researched area by examining health and work impacts on the aging for the bestknown and most influential of these programs, the Mexican PROGRESA/Oportunidades program. For a number of health indicators, the program appears to significantly improve health, with impacts that are larger with a greater time receiving the program. However, most of these health impacts are concentrated on women.
