The Chaco Area Reproductive Ecology (C.A.R.E.) Program, established in 1998, aims at advancing our understanding of the interaction between reproductive patterns and the ecological context in populations of the Gran Chaco region of Argentina.

The C.A.R.E. program has several long-term objectives:

·        To study the impact of the drastic lifestyle changes that the indigenous populations are experiencing on their fertility.

·        To investigate the effect of transculturation on the health status of Chacoan indigenous populations.

·        To explore the influence of child rearing practices on infant and children’s growth and  development.
