We dichotomized LOC eating (0 = <i>absent</i>; 1 = <i>present</i>) and scored CVH metrics using Life's Essential 8 to create a composite CVH score (range = 0-100; higher = better). Linear and binary logistic regression models tested if LOC eating is related to composite CVH score and odds of scoring <i>low</i> (0)/<i>moderate-high</i> (1) on each CVH metric, respectively.
