Table 3. Adjusted Odds Ratios^a for the Likelihood of Insufficient Sleep or Rest in the Previous 30 Days and β Coefficients^b for Days of Insufficient Sleep or Rest Associated With Airport Noise Exposure Zone, Behavioral Risk Factor Surveillance System, 2008 and 2009.

Zone	All 30 days,c OR (95% CI)	No Days,d OR (95% CI)	Number of Days, β (95% CI)
≥65 dB	0.86 (0.58 to 1.28)	0.95 (0.69 to 1.32)	0.74 (−1.37 to 1.52)
60 dB to <65 dB	1.04 (0.78 to 1.40)	0.96 (0.77 to 1.21)	0.49 (−0.85 to 1.08)
55 to <60 dB	0.82 (0.66 to 1.00)	0.98 (0.84 to 1.15)	0.32 (−1.02 to 0.25)
Outside exposure zone	1.00 [Reference]	1.00 [Reference]	0.00 [Reference]

Abbreviations: CI, confidence interval; dB, decibel; OR, odds ratio.

^a Adjusted ORs and 95% CIs obtained from multivariate logistic regression analyses that included year, age, race/ethnicity, education, income, weight status, and smoking as covariates.

^b β coefficients and 95% CIs obtained from multivariate linear regression analyses that included year, age, race/ethnicity, education, income, weight status, and smoking as covariates.

^c The likelihood of reporting all 30 days versus zero to 29 days of insufficient sleep or rest in the previous 30 days.

^d The likelihood of reporting no days versus 1 or more days of insufficient sleep or rest in the previous 30 days.
