Mode of birth and PTSD
Due to the variation in study methodology and outcome measures, it was
not possible to perform meta-analysis across all studies for all of the
review questions. Categorisation of mode of birth varied considerably.
Mode of birth also tended to be a secondary outcome in studies, and
rather than reporting individual statistics, many studies simply
performed an analysis of variance for all modes of birth.
For this reason, the only comparison possible across all studies was
whether mode of birth was significantly associated with symptoms of
PTSD. Overall, eight of the studies found significant variance in
symptoms of PTSD across the modes of birth they investigated . The
remaining four studies did not find a significant association between
mode of birth and PTSD .
