Abstract

OBJECTIVE: To investigate the relationships between psychological and physiologic measures of stress, mood, and gestational age at delivery and preterm birth. METHODS: This prospective cohort study recruited healthy women in the early second trimester who were 18-45 years of age. Validated psychological measures of perceived stress, depressive symptoms, and anxiety were completed at 16, 22, 28, 34, and 40 weeks of gestation. Cortisol concentration was measured in maternal hair at 16, 28, and 40 weeks of gestation to approximate first-, second-, and third-trimester levels of physiologic stress. Statistical methods included: analyses of variance, t tests, χ, Pearson correlations, regression modeling, and mediation analysis as appropriate. Hair cortisol concentrations were natural log-transformed to normalize values. RESULTS: Eleven (12%) of the 90 included women had a spontaneous preterm birth or preterm premature rupture of membranes. Perceived stress at 16 weeks of gestation correlated with both second-trimester cortisol concentration (r=0.28, P=.007) and earlier gestational age at delivery (r=-0.30, P<.01). Gestational age at delivery was also negatively correlated with cortisol concentration in the second trimester (r=-0.25, P=.02) and second-trimester cortisol concentration was higher in preterm- (2.7 ± 0.4 log-transformed pg/mg) compared with term- (2.0 ± 0.7 log-transformed pg/mg, P<.001) delivered women. Using mediation statistics, the association between the psychological measure, the physiologic measure, and gestational age at delivery was mainly driven by increased physiologic stress (hair cortisol concentration) in the second trimester (difference in coefficients [standard error]=-0.05 [0.02]). CONCLUSION: Higher perceived stress in the second trimester is associated with both elevated second-trimester hair cortisol concentration and gestational age at delivery. Physiologic measure of stress in the second trimester appears most strongly associated with preterm birth. Identification and amelioration of early pregnancy stressors may attenuate physiologic stress and ultimately affect preterm birth.

  • Formal prospective tests of biological mediation are rare among studies of adult stress effects on HPA activity and birth timing.

    “Of studies assessing effects of stress in adulthood on HPA activity and birth timing, formal, prospective testing of biological mediation is rare (Hoffman et al., 2016; Mancuso et al., 2004).”
  • The study provides preliminary support for the accelerated placental clock theory, consistent with some but not all prior studies.

    “We also provide preliminary support for the accelerated “placental clock” theory, which is consistent with some (Guendelman et al., 2008; Hobel et al., 1999; Hoffman et al., 2016; Mancuso et al., 2004; Moog et al., 2016), but not all (Himes and Simhan, 2011; Karakash et al., 2016; Kramer et al., 2009; Kramer et al., 2013; Noll et al., 2007; Owen et al., 2017), prior studies.”
  • In longitudinal studies, various HPA markers in the second and third trimesters have some predictive power for birth timing.

    “In longitudinal studies, various HPA markers in the 2nd and 3rd trimesters provide some predictive power for birth timing (e.g., Hobel et al., 1999; Hoffman et al., 2016).”
  • Women with increased life event stress during the first trimester of pregnancy had 2.40 times the risk of preterm birth compared with women with average or below-average stress.

    “in these studies, women with increased life event stress during the first trimester of pregnancy had 2.40 times the risk of PTB compared with women with average or below-average stress.80”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
