To determine the association of stress, anxiety and risk of spontaneous preterm delivery. Methodology: This study is correlational, longitudinal. The sampling was not probabilistic consecutive cases. 124 women pregnant were applied two different instruments in three different weeks 20-24, 30-34, 35-36. The first one to see the psychosocial status of the anxiety using instrument "The Spielberger State-Trait anxiety Inventory" (STAI), Cronbach's alpha 0.90. And the perceived stress with the "Perceived Stress Questionnaire" (PSQ) Cronbach's alpha > 0.70. Results: The incidence of spontaneous preterm delivery was 6.4 %, perceived stress did not increase the risk of spontaneous preterm delivery ( RR 1.01, confidence interval 95% [CI], 0.24 - 4.3 p < 0.05; Anxiety did not increase the risk of spontaneous preterm delivery ( RR 0.57, 95% [CI], 0.19-1.7 p <0.05). Conclusion: The perceived stress and anxiety did not increase the risk of spontaneous preterm delivery.
