Abdul El‑Sayed Faces Backlash Over 2011 Study Linking Interethnic Mating to Preterm Birth

Right-leaning outlets and Republican operatives have labeled the decade-old paper racist despite the study’s own caveats that its findings are tentative and require further research.

Overview

The 2011 paper, credited to Abdul El‑Sayed as primary author, reported about an 18 percent higher risk of late preterm birth (around 34–36 weeks) for Arab‑American mothers with non‑Arab fathers in Michigan.
The study itself offered multiple possible explanations, naming genetic hypotheses and social or environmental causes such as stress, discrimination, smoking, marital status and socioeconomic differences, and it explicitly called for more research to test causal mechanisms.
On Saturday, October 17, right‑leaning outlets and commentators republished the paper and some Republican figures publicly called it racist or likened it to eugenic thinking, making the decade‑old research a campaign issue.
Coverage resurfacing the study also repeated previously reported questions about El‑Sayed’s professional background and cited NRSC communications that used stark language and offered limited sourcing for broader allegations.
Scientists and journalistic standards note that single, older studies need replication and context, so the paper’s narrow geographic and temporal scope and its caveats limit how much it can be used to draw conclusions about El‑Sayed’s beliefs or public‑policy positions.
