“…Pregnancy-related anxiety at 28-30 weeks (but not at 18-20 weeks, and not state anxiety or general perceived stress) was modestly correlated with gestational length (β = -0.14, P < .05) but not with PTB (P = .09) [285], confirming previous findings [286]. Some adequately adjusted studies found no association between PTB and psychosocial stress [289], anxiety and depression [509], or stressful life events [284,302]. Eating fewer than 3 meals and 2 snacks / day (which may represent a stressful life style or the effect of starvation) was significantly associated with PPROM (aOR 1.9, CI 1.02-3.4, n = 2065), but not with PTB occurring after PTL with intact membranes (aOR 1.1, CI 0.6-1.9) [510].…”

Preterm Birth: A Review

Preterm birth at less than 37 weeks gestation is a substantial burden to the community, representing a major source of infant death, severe handicap, and suffering for both victims and their families. Despite considerable research, little progress has been made in its prevention, partly because preterm birth is the endpoint of a silent multifactorial syndrome which begins long before labour starts. Infectious inflammation often plays a central role, but maternal susceptibility is probably also critical. Although progestogen treatment is preventive in some women with a prior history of preterm birth this will have little impact on the overall preterm birth rate unless effective treatment can be used in a much larger population of at risk women. An accurate screening test to identify such women is needed. The discovery of a screening test and of novel treatments requires a better understanding of the underlying biomolecular events. This paper gives an overview of the physiology and molecular biology of normal and abnormal pregnancy and parturition, the causes and consequences of preterm birth, and the difficulties of predicting and preventing preterm birth.

“…Some life‐event scales also incorporate measures of the individual’s response, such as stressfulness rating, which may reflect both event severity and host susceptibility. The evidence that stressful life events adversely affect gestational length or very low birthweight is modest, although recent studies provide more consistent evidence of a small effect 8 , 60 –66 . Although most studies evaluated only acute events, in three studies that reported associations between stressors and either preterm delivery 60 or very low birthweight 8 both acute and chronic stressors were assessed.…”

Numerous epidemiological studies of various kinds of stress and preterm delivery have produced either negative or weakly positive results. Those inconclusive findings could be either because of the absence of an association or because of recognised methodological problems that may have masked an association. The biological plausibility of the stress hypothesis provides one rationale for continuing stress research, using better study designs. To further this agenda, we propose an epidemiological model, based on the classic ‘host, environment, agent’ triangle of epidemiological causality. The host is the individual woman, more or less susceptible to stressor‐induced pathology. The environment includes the social and cultural conditions that are ongoing stressors as well as social and cultural modifiers of stress e.g. those factors that may influence how a particular stressor is experienced or what the physical response to it may be. The agent is the immediate emotional or physical stressor requiring her response. We draw from recent literature, published principally since 1990, to illustrate this model. This epidemiological model posits that whether the individual is overwhelmed by stressors depends not only on the strength of the agents but also upon host susceptibility to stress, as well as the background level of acute, environmental and contextual stressors, and the moderating influence of host, environmental and contextual resources for handling stress. Future research needs to be based on stress hypotheses that include all sides of the triangle, data collection instruments that adequately capture relevant stressors and stress responses, and analytical techniques capable of handling complex, multilevel relationships.

“…In ALSPAC, we used data collected from study mothers on over 40 different common and rare life events based on items suggested by Brown and Harris [23], Barnett et al [24] and Honnor et al [25] at 6 time points covering the prenatal period until 3 years after the child's birth. Details of the life event questions are available in Table S2.…”

Prenatal and Early Life Exposure to Stressful Life Events and Risk of Autism Spectrum Disorders: Population-Based Studies in Sweden and England

et al. 2012

Background and AimExposure to stressful life events during pregnancy has been suggested as a potential risk factor for offspring Autism Spectrum Disorders (ASD), but the literature is limited and inconsistent. We tested the hypothesis that maternal exposure to stressful life events would be associated with increased risks of offspring ASD, and that these risks would be highest for exposures during the prenatal period.Methods and ResultsWe used prospectively collected data from two large population based studies in Sweden and England. In the Swedish study of 4429 ASD cases and 43277 controls, our exposure comprised the occurrence of any severe life event before and during pregnancy and the child's early life. In the English study (maximum n = 11554, ASD n = 72), we studied the risk of offspring ASD in relation to a combined maternal exposure to multiple (up to 42) common and rare life events, as well as their perceived impact upon the mother during pregnancy and early life. In crude and adjusted regression analyses in both studies, we found no evidence of an association between prenatal life events, or their number and perceived impact and the risk of offspring ASD. Sub-group analysis of ASD with and without intellectual disability in the Swedish study yielded similar results.ConclusionWe found no evidence to support the hypotheses that exposure to stressful life events during the prenatal period is associated with an increased risk of offspring ASD.
