Effects of a Group-Based Cognitive Behavioral Therapy for Sleep in Nursing Students: Pilot Randomized Controlled Trial
(2026) Pérez Manchón, David; Azpeleta Noriega, Clara; Gal Iglesias, Beatriz; Ruiz Zaldibar, Cayetana
Sleep quality is a strategic public health priority and a key factor in the study of circadian rhythms and chronotypes. Nursing students are a particularly vulnerable population group. This pilot randomized controlled trial provides preliminary evidence that a brief group-based CBT-I intervention may improve selected subjective sleep outcomes, particularly sleep latency, among first-year nursing students. Objective circadian rhythm and sleep outcomes showed generally small treatment effects. Given the exploratory nature of this pilot study, adequately powered randomized controlled trials with longer follow-up are needed to confirm these preliminary findings.

Association between hearing loss, physical activity, and sedentary behavior: a nationally representative cross-sectional study in Chile
(2026) Morales, Camilo; Martínez Amezcua, Pablo; Caballero, Francisco Félix; Oliveros, María J.; Seron, Pamela; López García, Esther; Yévenes Briones, Humberto
Hearing loss is common in midlife and older adults and may constrain communication and participation, potentially shaping physical activity and sedentary time; however, population-based evidence remains inconsistent.
