A systematic review and meta-analysis of 21 studies found that mindfulness programs lasting 8 weeks to 3 months significantly improve mental health in university students. The review searched PubMed, Scopus, Web of Science, and CINAHL, initially identifying 321 studies. Methodological quality was assessed with the PEDro scale. The results demonstrate that mindfulness interventions are effective for enhancing the mental health of college students.
A systematic review and meta-analysis of 10 studies found that mindfulness-based programs reduce poor sleep quality in healthy non-institutionalized older adults. The overall effect size was moderate and negative (Hedge's g = −0.344, 95% CI −0.425 to −0.263), indicating improvement. Subgroup analyses showed similar effects across measures: Insomnia Severity Index (g = −0.326), Pittsburgh Sleep Quality Index (g = −0.343), and Sleep Onset Latency (g = −0.28). The authors conclude that mindfulness could be a viable treatment option for insomnia or other sleep problems in this population.
