摘要

I was interested in the paper by Wisborg et al. reporting their results from a large prospective study on the relation between psychological 'stress' and stillbirth. They conclude that psychological stress during pregnancy was associated with an increased risk of stillbirth. However, the data donot support this conclusion. Rather, they support the opposite conclusion.Stress was measured by the 12-item General Health Questionnaire (GHQ-12) as described by Wisborg et al. The scale score was categorised into three groups with low, intermediate and high scale scores. The simplest a priori hypothesis on the relation between stress and stillbirth would be that the risk of stillbirth increased with increasing level of stress. This hypothesis may be examined in models with stress as a continuous or as a categorised covariate in logistic regression analyses. The authors only examined the effects of stress by the three stress categories mentioned above.
