The very first sentence has a link to the paper. That paper is really interesting, for example how the authors had to cull the data to get to usable factual data that had the true cause of death.

I rather like science blog posts like this compared to what is more typical and this post mentions what your concern is in paragraph three of four. No where in those four paragraphs does it leap to the conclusion "therefore those parents are the cause of the high number."
