Systematic review identifies effective non-drug strategies to improve sleep quality in older adults, suggesting better management options.

This research aims to compare the effectiveness and acceptability of non-pharmacological treatments for enhancing sleep quality in older adults.
Conducted a systematic review and network meta-analysis of randomized controlled trials.
Included trials focused on adults aged 50 and older with sleep disturbances.
Evaluated 25 predefined non-pharmacological treatments for sleep quality.
Utilized Bayesian methods and risk ratios under random-effects models for analysis.
Meta-regression examined nonlinear associations with baseline sleep severity and intervention frequency.
Nineteen non-pharmacological treatments significantly improved sleep quality compared to control conditions.
Combined aerobic and resistance training showed the largest effect (-1.56 standardized mean difference).
Fourteen treatments met the minimum clinically important difference; key successful ones were combined aerobic and resistance training, acupressure, and aerobic exercise alone.
Meta-regression suggested maximal benefit with interventions for individuals with baseline Pittsburgh Sleep Quality Index scores around 16.
Only usual care had a lower dropout rate compared to control.
