LE8 score was calculated from 4 health factors (body mass index, non\u2013high\u2010density lipoprotein cholesterol, fasting glucose, and blood pressure), and 4 health behaviors (dietary intake, physical activity, tobacco use, and sleep). LS7 was calculated from 7 metrics (all LE8 metrics, except for sleep) with a simpler algorithm. Higher LE8 and LS7 scores both indicate better health and better adherence to American Heart Association guidelines. Carotid artery outcomes included carotid artery intima\u2010media thickness, arterial stiffness (eg, distensibility), and echogenicity determined by grayscale median of the intima media complex. Results of linear regression analyses, adjusting for age, sex, ethnicity, and parents' highest degree, indicated that a 1\u2010SD increase in LE8 score was associated with 12.14\u2009\u03bcm lower carotid artery intima\u2010media thickness (95% CI, \u221220.93 to 3.35), 1.17 (10\n              <jats:sup>\u22126<\/jats:sup>\n              \u00d7m\n              <jats:sup>2<\/jats:sup>\n              \/N) greater distensibility (95% CI, 0.09\u20132.24), suggesting less arterial stiffness, and 2.66\u2009\u03bcm greater grayscale median of the intima media complex (95% CI, 0.58\u20134.75), suggesting less lipid deposition.
