Every one-hour change in sleep duration (SDUR) has a dose-response impact on cardiovascular disease and mortality. However, self-reported SDUR may not represent the real time significant proportion of adult population. This study was designed to determine frequency potential under/overestimation when comparing subjective versus objective data. Consecutive adults from ELSA-Brasil collected underwent wrist actigraphy for seven days. We defined underestimation (underSDUR) overestimation (overSDUR) differences between reached at least -1/+1-hour, respectively. performed multinomial logistic regression analyses identify independent factors under- overSDUR. Data 2,036 participants were used final analysis (42.7% males; age: 49±8 years). The underSDUR overSDUR 19.4% 19.7%, predictors included black race (OR: 1.65; 95% CI: 1.79–3.93), mixed-race 1.69; 1.20–2.38); daytime sleepiness 1.37; 1.05–1.80); longer 3.00; 2.54–3.56); wake after onset time, WASO 2.19; 1.22–3.95), moderate/severe insomnia 2.54; 1.78–3.63). Longer 2.26; 1.33–3.82), higher number awakenings 1.02; 1.00–1.03) independently associated with found rate While black/mixed race, sleepiness, WASO, specifically markers fragmentation.
