Obesity is defined as a BMI greater than or equal to 30.0 (27.5 for Asians). Hypertension is defined as a seated SBP greater than or equal to 140 mmHg, a seated DBP greater than or equal to 90 mmHg, or use of medication for hypertension or high blood pressure. Diabetes is defined as a fasting blood glucose greater than or equal to 126 mg/dl or use of medication for diabetes or high blood sugar
The adjusted model includes as covariates age, gender, race/ethnicity, education, work status, smoking status, alcohol status, and waist circumference.
Unit of duration is standard deviation.
Unit of fragmentation is 1 percentage point.
Unit of Daytime Sleepiness is 1 point on Epworth.
Unit of Quality is 1 point on PSQI, limited analyses to 339 participants who had PSQI score
