A few notes after reading the study allegedly linking acetaminophen to NDD’s.
1) This study was a qualitative synthesis of many published articles. They took a bunch of existing research and cross-analyzed it for patterns. It’s very common, but it’s an important distinction that the authors did not conduct additional research.
2) Because it’s a qualitative synthesis (rather than a quantitative meta-analysis), this makes it harder to compare studies from a numbers perspective. Each one is given similar weight, regardless of contributing factors, sample sizes, and other research practices.
3) Correlation does NOT imply causation. From their analysis, the authors gleaned that there may be a casual relationship between acetaminophen and NDDs. The general consensus was that prolonged and unsupervised usage poses a potential danger, but this is generally accepted. When faced with other dangerous ailments though, the potential risks of acetaminophen may be worth it to avoid fetal harm.
4) More research is needed. Inserting my own opinion now, future studies should also account for other variables such as the quality of air, water, and food, economic status, family health, and access to consistent medical care.
5) But is there a connection? Maybe, maybe not! One synthesis should not upturn an entire system. If you’re uncomfortable using acetaminophen based on this study, don’t use it. That said, don’t also treat this study’s inconclusive findings as fact.
From a research perspective, flash headlines make me shake my head because they don’t provide necessary context. They whip people into a frenzy and muddy the work of researchers. When in doubt, the original source material is *always* the best source of information.
