ORTIZ MARTINEZ, Roberth Alirio  e  CASTILLO, Alejandro. Relation Between Stress During Pregnancy and Spontaneous Preterm Birth. rev.colomb.psiquiatr. [online]. 2016, vol.45, n.2, pp.75-83. ISSN 0034-7450.

Background: Preterm birth occurs before 37 completed weeks, its causes are multifactorial and vary according to the gestational age, ethnicity and geographical context. Although several medical/social factors have been clearly identified, over 50% of cases are unknown or unclear; however, psychopathological components emerge as potentially important risk factors. Objective: To determine the relationship between the presence of stress during pregnancy and spontaneous preterm birth. Material and methods: Through a study of cases and controls in a level III hospital, with a sample of 360 patients during the period from March to November of 2013, where socio-demographic characteristics were collected. In addition, they were applied scales social adjustment, coping strategies and social support. Logistic regression models were developed; psychological, biological and social. Based on the significant variables in each of these generated a final one. Results: The final model was found that stress during pregnancy increases the odds of spontaneous preterm birth 1.91 times (adjusted OR = 2.91; 95%CI, 1.67-5.08; P<.05). Other significant variables were: history of preterm delivery, unplanned pregnancy, no emotional support, rural residence, inadequate prenatal care and non-stable partner. Conclusions: The findings support the hypothesis that stress during pregnancy is associated with spontaneous preterm delivery.
