Severity/Burden
When aggregating physical health conditions to assess the burden of conditions, 34% of participants (n=307) were classified as having a high to severe burden score, 56% were classified as having a medium burden and 10% (n=90) were classified in the none to low reference group (Supplemental Table S3). In models adjusted for age, sex, race/ethnicity, BMI, and physical inactivity, short sleep duration with a prolonged SOL was associated with a high/severe burden of chronic health conditions (OR 2.35, 95% CI 1.12-4.94) compared to those with a low to none burden. No other measures of short sleep duration were significantly associated with medium or high/severe burden of health conditions (Figure 1, Supplemental Table S4).
