This supplemental material accompanies a research study examining whether aircraft noise exposure is linked to poorer sleep among women in the Nurses' Health Study, a large U.S. health cohort. The study measured nighttime and day-night aircraft sound levels near 90 U.S. airports and analyzed their association with self-reported short sleep duration and poor sleep quality. Researchers used detailed statistical methods, including directed acyclic graphs and multivariable models, to account for confounding factors and assess exposure-response relationships.Open full document
Notes
This supplemental material accompanies a study published in Environmental Health Perspectives examining associations between aircraft noise exposure and self-reported sleep duration and quality among participants in the Nurses’ Health Study cohort. The document contains a table of contents listing supplemental tables (S1–S6) and figures (S1–S2), including directed acyclic graphs, sensitivity analyses, and exposure-response data. The study uses nighttime aircraft sound levels (Lnight) and day-night sound levels (DNL) as primary exposure metrics.
