The second paper looked at physical strain taking place during the time of
implantation in women experiencing their first pregnancy. Neils Henrik Hjollund
of the Aarhus University Hospital in Copenhagen, Denmark, and lead author of
the paper writes, "The analysis included 181 pregnancies. ... Physical
strain around the time of implantation was associated with later spontaneous
Women participating in the study were asked to keep a special diary during
the time they were trying to get pregnant. Information on sexual intercourse,
vaginal bleeding, and physical activity and strain was recorded. An association
between increased physical strain around the time of implantation and
spontaneous abortion was seen.
Dr. Carl Weiner, MD, professor of obstetrics and gynecology at the
University of Maryland School of Medicine, commented on this study for WebMD.
He says, "This study is provocative because of the prospectively kept
diary. Still, it's difficult to propose a mechanism whereby someone would be at
increased risk for adverse implantation because of physical strain. The
possibility can't be excluded but I'm not convinced by this study."
- A new study shows that women experience stress around the time of
conception are more likely to deliver babies with birth defects or miscarry,
compared with those who do not experience stress.
- One problem with the study is that it was retrospective, and women who have
bad outcomes are more likely to remember the negative events that occurred
during pregnancy, according to one expert.
- A second study on pregnancy showed that physical strain around the time of
implantation increased the risk of spontaneous abortion.
