Participants completed seven consecutive nights of wrist actigraphy and daily sleep diaries. Sleep health parameters were compared between PLWH and PWoH using linear mixed-effects models for repeated measures and linear regression for participant-level variability measures. Intraclass correlation coefficients and the Spearman\u2013Brown formula were used to estimate the number of nights of monitoring required for reliable measurement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 100 participants (50 PLWH and 50 PWoH), 70% were female, and the median age was 49\u00a0years (IQR 44\u201354). Based on actigraphy data, PLWH had shorter mean sleep duration than PWoH (adjusted mean difference (aMD) \u221232.1\u00a0minutes, 95% confidence interval (CI) \u221252.6, \u221211.7). Bedtimes were slightly later (aMD 17.4\u00a0minutes, 95% CI \u22122.4, 37.3) and wake-up times slightly earlier (aMD \u22122.1\u00a0minutes, 95% CI \u221221.6, 17.3) among PLWH compared with PWoH. PLWH also exhibited greater night-to-night variability in sleep duration (aMD in standard deviation 13.1\u00a0minutes, 95% CI 1.2, 25.0). Actigraphy-derived sleep measures required at least 7 nights for reliable estimates, whereas self-reported sleep quality required at least 3 nights.<\/jats:p>\n                  <\/jats:sec>\n
