Hazard ratios (95% CIs) for associations between aircraft noise (DNL ≥55 dB(A) vs. <55 dB(A)) and hypertension in NHS and NHS II in basic (age), fully-adjusted, and sensitivity models (noting person-years). Fully Adjusted Model: Adjusted for age, calendar year, race, menopausal status, family history of hypertension, BMI, physical activity, smoking status, alcohol use, DASH, medication use (current statin and NSAID use), spouse’s education attainment, nSES (Census tract home value and household income), and region of residence. Sensitivity 1: Excluding observations under 45 dB(A). Sensitivity 2: Excluding observations greater than or equal to 65 dB(A). Sensitivity 3: Further adjustment for PM2.5 and PM2.5-10 (NHS: 1994-2008, NHS II: 1995-2009). Sensitivity 4: Further adjustment of fully-adjusted model for current night shift work in NHS II only.
