Primate Evidence on the Late Health Effects of Early Life AdversityGabriella ContiUniversity of Chicago Christopher Hansmanaffiliation not provided to SSRN James J.

We analyze the health records of 231 monkeys which were randomly allocated at birth across three rearing conditions: Mother Rearing, Peer Rearing, and Surrogate Peer Rearing. We show that the lack of a secure attachment relationship in the early years engendered by adverse rearing conditions has detrimental long-term effects on health which are not compensated by a normal social environment later in life.
