n=2760 for model 1; n=2565 for model 2; n=2554 for model 3.

Model 1: adjusted for age, sex, and ethnicity.

Model 2: adjusted for age, sex, ethnicity, ratio of family income to poverty level, physical activity, and smoking.

Model 3: adjusted for age, sex, ethnicity, ratio of family income to poverty level, physical activity, smoking, BMI, and history of hypertension

Bold values indicate significant findings.

BMI, body mass index; IS, interdaily stability; IV, intradaily variability; L5, least active continuous 5-hour period; M10, most active continuous 10-hour period; RA, relative amplitude.
