Systematic Review and Meta-Analysis on Dairy Intake and Cognitive Function in Older Adults

A 2026 systematic review and meta-analysis by Yessica Giraldo-Castrillon, evaluating the association between milk and dairy product intake and cognitive function in adults aged 60 years and older. The analysis included 22 studies (n=47,100), comprising 11 randomized controlled trials and 11 observational studies, sourced from PubMed, Scopus, LILACS, and Google Scholar up to August 2025.

Use Cases

• Conducting secondary meta-analyses based on the reported standardized mean differences and odds ratios.
• Evaluating methodological quality of nutrition studies based on the described RoB 2.0, ROBINS-I, and GRADE assessments.
• Investigating the differential effects of fermented and fortified dairy products on cognitive domains like memory and processing speed.
• Designing clinical trials or observational studies on dietary interventions for older adults based on the reviewed evidence.

Strengths

• Includes 22 studies with a total sample size of 47,100 participants.
• Applies multiple established quality assessment tools (RoB 2.0, ROBINS-I, GRADE).
• Reports specific effect sizes (SMD=0.45 for RCTs on global cognition) with confidence intervals.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is a single 103.4 KB document, indicating a limited scope of raw data.
