In my practice we’ve looked at the prepregnancy size of the mom (not her
BMI) as a risk for ASD. Our own experience is that many of the mothers of
individuals with autism are small, often being unusually short, or with normal
height but they have unusually small bones. This isn’t picked up by the
BMI choice made by the authors. We find that the child of the small mom is at
risk for ASD. The BMI does not give regard to the height, while the small-size
concept takes a proportional view. It would do well for all of us to
politely recognize that parents (especially women) feel guilty enough about
being told they’ve caused their child’s autism, without the rather
cold announcement that the latest factor is gaining weight in gestation. We
simply have not found a 30% increase in the chance of a woman’s child
developing ASD by an extra pound when she’s pregnant.
Wow. The study that launched a million maternal guilt trips....
I was so impressed with the sensitivity of these researchers, that they would
emphasize repeatedly that gestational weight gain is not the mother's
fault. Having a baby puts the mother's body through incredible stress and
introduces a new and complex set of genetic interactions. Weight gain, before
and after birth, is often an unavoidable result. Having a child is
the most noble sacrifice a person can make. This needs to be said on other days
besides Mother's Day.
I would love to see the more data on this. From data gathered elsewhere, under
weight mothers have been also attributed to low weight child births, as well as
a close correlation to mothers not going full term. This is again a story of
this being only a portion of a very complex story. While it is popular to blame
all ailments on over weight, in pregnancy specifically, mothers who restrict
calorie intake or undergo heavy workout programs has been shown to equally be
problematic for child development.Lots more questions to be answered
here.... stuff like this miss applied could cause more damage than the intended
good. That said, I am not a doctor... I just look at their data....
