Most patient-reported sleep measures focus on body functions, not function or environment

Systematic content analysis of 27 patient-reported sleep measures mapped items to ICF categories and semantic relations. Overall 71.5% of meaningful concepts linked to body functions, with only 14.7% to activities and participation and 3.5% to environmental factors. Semantic analysis showed items often framed symptoms within activities rather than measuring downstream functional or environmental impact. Constructs labeled similarly varied in operationalization across instruments, so questionnaire labels may not reflect actual item content. 1

Tailored public-health efforts associated with improved AAP safe-sleep knowledge among Black birthing people

Nested case-control in a prospective cohort (N=606) compared demonstrated knowledge of five AAP safe-sleep factors between 2011–2014 and 2019–2022. Both non-Hispanic Black and White participants significantly increased guideline knowledge over time (p = .01 and p < .01 respectively). Pre-intervention, Black participants were less likely to demonstrate knowledge than White peers (OR 0.52, 95% CI 0.31–0.85). Post-intervention the racial difference was not statistically significant (OR 0.36, 95% CI 0.13–1.03), suggesting improved parity in awareness. 2

Morning blue light therapy yields modest improvements in sleep quality and continuity in adults with insomnia

Meta-analysis of 14 RCTs (n=444) found blue light therapy improved subjective sleep quality (MD = -1.895) and reduced excessive daytime sleepiness (MD = -0.970). Objective improvements included shorter sleep onset latency (Hedges' g = -0.545), less waking after sleep onset (g = -0.563), and improved sleep efficiency (g = 0.429). Blue light did not reliably change total sleep time, time in bed, or fatigue, and effects varied by device, duration, and intensity. Authors advise cautious interpretation and further trials to define optimal dosing and patient selection. 3
