Maternal stress increases risk of premature delivery
THERE IS a connection between maternal psychological well-being and the birth outcome.
As investigators at the Veterans Administration have found, maternal stress brings risk in preterm delivery. This was based on their evaluation on the link between active posttraumatic stress disorder (PTSD), or historical PTSD and risk for preterm birth.
Investigators used electronic medical record and data from compulsory assessment of PTSD in military personnel.
From >16,000 deliveries, 19 percent were women with PTSD (12 percent were with active PTSD). Investigators found 9 percent higher risk for spontaneous preterm delivery among women with active PTSD than those with historical PTSD (8 percent) or no PTSD (7 percent).
Moreover, the excess risk persisted after adjustment for possible confounders. The said study revealed that most women with active PTSD had experienced military sexual disorders and depressive disorders.
Meanwhile, in a different study, a randomized 64 urban, low-income, pregnant black women (gestational range at entry) received supplementation with docosahexaenoic acid (DHA), 450 mg/day or placebo until delivery.
At the 30 weeks’ gestation, stress was lower in the DHA group than those in placebo group. The study added that DHA recipients had lower cortisol output in reaction to arriving at the research laboratory, and a better-modulated response to social stress test. Ma. Cristina C.
