The Pregnancy-Specific Stress How Factor Risk for Preterm Birth

Citation: The Pregnancy-Specific Stress How Factor Risk for Preterm Abstract Preterm birth (PB) has a multifactorial etiology and psychosocial stress can be a risk factor. Objective. Quantify the as sociation of the specific stress of pregnancy with PB. Material and methods. A case-control study was conducted in 254 preterm mother-child dyads and 254 term dyads, between 2010 and 2011, at the Civil Hospital of Guadalajara. The dependent variable was PB (24-36 weeks of gestation) and the independent stress specific to pregnancy. Gestational age was confirmed with the Capurro and Ballard methods. The specific stress of pregnancy was sought by direct interview. We inquired about psychosocial, obstetric and illicit drugs. The association was evaluated with logistic regression. Results. The age of the mothers was 25 ± 6 years. The frequency of psychosocial factors and drug use was similar. In the bivariate analysis were more frequent in PB, antecedent of PB (OR: 1.98, CI95%: 1.17-3.36), diseases in pregnancy (OR: 1.49, CI95%: 1.03-2.17), multiple pregnancy (OR: 14.72, CI95%: 4.28-60.63), being born by caesarean section (OR: 4.93, CI95%: 3.26-7.48, worrying about work and family care (OR 1.60, CI95% 1.01-2.55) and paying for clothes, food and medical expenses of the baby (OR 1.55, CI95% 1.00-2.39). A multivariate model identified as covariates associated with PB to worry a lot about the care of the new baby (OR 2.58, CI95% 1.21-5.47) and to be born by caesarean section (OR 5.59, CI95% 2.63-11.90). Discussion and conclusion. Of the variables related to specific stress of pregnancy, only worry much about the care of the baby was associated with PB, as well as being born by cesarean section.
