In fact, my understanding is that a baby three weeks early isn't even classified as a preemie. Correct: 37 weeks is considered "term", with a standard due date being somewhere between 39 and 40 weeks. My son was ~3 weeks early: he was totally fine, but definitely a "oh, I guess this is happening now!" moment. Anecdote: he was 7lbs. 7oz. (right around average) and 3 weeks early. He likely would have been a monster at his due date, and may have been a c-section because he just would have been too big. Is that normalized in the study? Or are we flipping causation? Instead of "c-sections are correlated with obesity risk", is it "obesity risk is correlated with c-section"?
