Several models inspired by the life history theory have assessed the patterns of human reproduction in developed countries with promising but inconclusive results. Considering the diversity of life conditions in Brazil, we investigated the relationship between the time of main events in female reproductive life, environmental conditions and psychosocial variables related to child-rearing. We interviewed 606 women in six different states in Brazil. Results corroborate the life history theory, showing associations among the investigated factors, especially between life conditions during childhood and the beginning of sexual life and reproduction, but not to sexual maturity. We suggest that landmarks in reproductive life, although related, can be under the influence of several phenomena. Diversity of life conditions in Brazil offers alternative contexts to hypotheses testing.
