Obese Women More Likely to Have Children with Autism

Here’s a not-to-surprising study showing that obese women are at higher risk of having children with autism. Obese women were 67% more likely to have an autistic child, and about 2x as likely to have an child with another developmental disorder. Having gestational diabetes also raised by 2x a mother’s risk of having a baby with developmental disorders.

They also note that nearly 60% of women of childbearing age in the US is overweight and about 1/3 are obese. Obesity rates are rapidly climbing. Autism rates are also climbing, with the latest report showing 1/88 children having one of the autism spectrum disorders.

The authors mentioned every possible explanation (diabetes, high blood pressure, fluctuating glucose levels, lack of oxygen) expect for obstructive sleep apnea. I’ve written numerous times in the past about complications of obstructive sleep apnea during pregnancy. If you’re overweight or obese, you’re much more likely to have obstructive sleep apnea. One of the hallmarks of sleep apnea is hypoxia and major physiologic stress on the mother’s body. I wonder what the effect is on the developing baby’s brain? It would make sense to routinely screen for sleep apnea in all women, especially if you’re overweight or heavier.

If you were overweight during pregnancy, did your doctor screen you for obstructive sleep apnea?
