History of eating disorder associated with delayed depressive recovery in bipolar disorder. Two-year survival curves for depressive recovery in depressed bipolar disorder patients indicated significantly delayed depressive recovery in patients with (N = 29, black line on right) vs. without (N = 124, gray line on left) lifetime eating disorder (Log-Rank p = 0.043). Lifetime eating disorder was also significantly associated with delayed depressive recovery using Cox Proportional Hazard analysis [Hazard Ratio (HR) = 0.54 (95% Confidence Interval (CI) = 0.29–0.99), p = 0.047]. No assessed demographic (not even gender) or clinical parameter significantly mediated delayed depressive recovery in patients with vs. without lifetime eating disorder
