A systematic review and meta-analysis of 35 randomised trials in adults aged 50 and over links combined lifestyle measures, Mediterranean-style diet, aerobic and resistance exercise, cognitive engagement, social support, sleep and preventive care, with better ageing outcomes, including a 25% lower risk of cognitive decline with 7-8 hours of sleep.
What it shows: Review of 35 RCTs (~25,000 participants aged 50+), but it pools very different interventions and outcomes into single estimates, and some reported associations (notably on alcohol and sleep) read as observational and are loosely described in the abstract.Meta-analysis · Invest Educ Enferm
