From: Long-term risk of mental health problems in women experiencing preterm birth: a longitudinal study of 29 mothers

Dependent variable Independent variable B 95% CI Beta p value R 2 adj
IES Preeclampsia 5.75 (1.22, 10.27) 0.37 0.015  
  IVHa 11.34 (3.17, 19.50) 0.39 0.008  
  Mother's age 0.91 (0.18, 1.64) 0.36 0.016 0.41
GHQ Likert Bleeding in pregnancy −7.57 (−12.55, −2.59) −0.44 0.004

  1. The mean of mental health outcomes assessed by IES, GHQ and STAI-X1 at the infant's 6- and 18-month post-term ages was used as outcome. Unstandardized (B) and standardized (beta) regression coefficients from multiple linear regression analyses after forward stepwise variable selection are reported. N = 33. aThe child was struck by intraventricular haemorrhage grade 1 or 2 shortly after birth; bTen-question version of STAI-X1.
