Apart from the medical complications mentioned by Dr. Macones, preterm labor has frequent, and often serious, psychological consequences. As already stated in our article, preterm labor increases the level of maternal anxiety and alters the quality of life during pregnancy. More specifically, prescriptions such as prolonged bed rest may increase the risk of depression.
It is very usual, in France, to have serial cervical assessments during pregnancy. In our hospital, all pregnant women have to attend a compulsory prenatal visit each month, most of them starting before the end of the first trimester. Cervicovaginal examination is systematically conducted at each of these visits.
The assumption that "the 'diagnosis' of preterm labor was presumably given only to women who had 'complaints' of contractions that necessitated a visit to the obstetrician" (1, p. 303) is not accurate. As mentioned in the article (2
), preterm labor is systematically queried at each compulsory routine consultation. One of these compulsory consultations necessarily took place during the enrolment phase of our study. As a consequence, a diagnosis of preterm labor may be made quite independently from any visit motivated by complaints of contraction or other complaints.
Possible biases regarding the relation between anxiety and preterm labor cannot be applied to depression. This disorder, especially in its major form, differs from anxiety in its manifestations. Depressed women exhibit a tendency toward inhibition and withdrawal and as a result are not likely to express complaints or seek multiple visits, unlike anxious women. It is thus very unlikely that the magnitude of the strong association we found between depression and preterm labor might be falsely increased.
