While many adults with Long COVID experience sleep problems, the long-term relationship between Long COVID and sleep remains poorly understood. We investigated how Long COVID is prospectively associated with sleep duration, sleep quality, and sleep disturbance using a population-based cohort of Michigan adults with COVID-19 (n=2,406). Long COVID was defined at baseline as reporting a recovery time of 90 days or more after the initial infection and sleep outcomes were assessed at follow-up 1 and 2, approximately 1. 5 years and 3 years after the initial infection. We estimated linear and multinomial logistic regression models with sleep duration as continuous and categorical variables, respectively. Then, we conducted multinomial logistic regression models for sleep quality and modified Poisson regression for moderate-to-severe sleep disturbance. Long COVID was prospectively associated with a shorter sleep duration by 0. 35 hours (95% CI: -0. 53, -0. 17) at follow-up 1. Relative to sleeping 6-9 hours, Long COVID was associated with sleeping
