A total of 310 athletes from 13 countries were announced to participate:[1]
Argentina (29),[2] Bolivia (5), Brazil (84), Chile (43), Colombia (36), Ecuador (24),
Guyana (4), Panamá (2), Paraguay (3), Perú (5), Surinam (2), Uruguay (6),
Venezuela (68). Athletes from the Dominican Republic (4), from the Netherlands
Antilles (4), and from Trinidad and Tobago (11) were invited as guest

* Keisa Monterola from Venezuela was then only 16 years old and could not
officially participate at the championships. Out of competition, she
cleared 3.80m in the first attempt, which would have placed her in the
second place of the competition.[7]
** Some sources list Jéssica Quispe from Perú to finish second in 4:27.68 in
the 1500m women's event.[4] Just as pole vaulter Keisa Monterola, she might
have started out of competition because of her age (she was then only 17 years old).
