Risk of Autism may be linked to closely spaced pregnancies

autism in siblings, pregnancy factors


Discussions and theories about etiology, diagnosis and treatment approaches of autism may be controversial and debatable, however recent studies in different areas produce some interesting and surprising results. It’s known about involvement of genes (fragile genes and genetic predisposition) of developing autism, pervasive developmental disorders (PDD). Ecological factors (that may affect developmental processes) are also discussed.

There are less supporters of linking of autism to standard childhood vaccination specially with new method of production of vaccine and one of the latest research conducted by Keely Cheslack-Postava, PhD, MSPH, Kayuet Liu, DPhil and Peter S. Bearman, PhD (Robert Wood Johnson Foundation Health and Society Scholars, Columbia University, New York, New York; and Paul F. Lazarsfeld Center for the Social Sciences, Columbia University, New York, New York). They conduct a study to determine if risk of autism could be linked to inter-pregnancy interval (IPI) in subsequent births.
The results of their research suggest that those children who born after shorter period between pregnancies may have higher risk of developing autism (the highest risk was among children born with less than one year between siblings).
Mothers prenatal health status plays very important role in developing a healthy child. Recent pregnancies, stress factors alter mother’s health status, ecology, exposure to hazards, physiological processes, availability of nutrition's for developing child that causes damage of developmental processes that leads to neurological and other pathological conditions in babies.
It’s known that some psychiatric conditions such as schizophrenia in younger sibling is linked to closely spaced pregnancy. Higher risk of autism in children born from close spaced pregnancy, genetic factors should increase awareness among health care providers and women planning their families and pregnancies.autism awareness

This research supports ideas that vaccination has nothing to do with developing of autism in children, however more research should be done to completely unlink vaccines and it’s ingredients from autism (Could it be some unknown component or mix of components of vaccine (even inactive ingredient) affecting fragile physiological process of developing functional interconnection between essential areas of child’s neuro system?).
