Associations between Prenatal Maternal Stress and Birth Outcomes
By Huaiyu Zhang
The literature on relationships between maternal prenatal stress and birth outcomes is mixed, partly attributable to the difference in operationalization of stress and birth outcome measures. This study aimed at applying a multivariate approach to assess these associations. Life event stress, perceived stress, and cortisol were included as stress indicators. Birth weight, gestational age, and Obstetric Complications Scale (OCS) were assessed as birth outcome measures. A total of 191 women were recruited for 2 prenatal visits, and their delivery information was collected from their medical charts. Statistical analyses included multiple linear regression, independent t test, chi square, and two-way ANOVA. For mothers of male babies, high cortisol levels during the third trimester were related to higher scores of stressful life events.Albeit preliminarily, the results indicate that maternal prenatal stress adversely impacts birth weight of male babies, and the consistency of cortisol levels during pregnancy is associated with birth weight of female babies. Further studies on contextualization of stress measures and improvement on statistical method are suggested.
