Eventos estresantes durante el embarazo aumentan significativamente el riesgo de parto prematuroPublicado el 20.07.2010

.
Un masivo estudio que incluyó 1800 pacientes demostró una asociación entre la ocurrencia de eventos estresantes durantes los 2 primeros trimestres del embarazo y el desarrollo posterior de parto prematuro. El efecto dependió de la intensidad de la medida de estrés y de otros cofactores conocidos.

Prenatal life events stress: implications for preterm birth and infant birthweightPeng Zhu, MDa, Fangbiao Tao, MDa, Jiahu Hao, MDa, Ying Sun, MDa, Xiaomin Jiang, MDab
Objective
The objective of the study was to evaluate the effects of maternal exposure to severe life events during different stage of gestation on preterm birth and infant birthweight.
Study Design
A sample of 1800 women who delivered after 32 weeks' gestation were assessed with questionnaires that measured stressful life events during different stages of pregnancy. Demographic characteristics and birth outcomes were collected through the interviewsand medical charts.

Results

There was an increased risk of preterm birthamong women with higher levels of life events stress during the first trimester (adjusted risk ratio, 2.40; 95% confidence interval, 1.13–5.09) and second trimester (adjusted risk ratio, 2.86; 95% confidence interval, 1.26–6.47). Each unit increase of perceived life events stress during first trimester was associated with a 99.09 g decrease in infant birthweight.

Conclusion

Prenatal severe life events, especially in the first trimester, may play an important role in increasing the risk of preterm birth and low birthweight.
