A Meta-Analysis of Multidimensional Cognitive Functions Changes in Different Intensities of High-Altitude Hypoxia.

ABSTRACT:

Purpose

This meta-analysis aims to comprehensively evaluate the impact of high-altitude hypoxia on multidimensional cognitive functions, considering moderating variables such as altitude, exposure time, cognitive domain, and experimental design.

Methods

A three-level meta-analysis was conducted on 59 studies (1966-2024) comprising 739 effect sizes. Studies were screened and coded according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Cognitive tasks were categorized into seven domains: executive control, working memory, long-term memory, perceptual ability, psychomotor skill, attention, and others. Hedges' g was used as the effect size measure, and multilevel modeling was applied to account for dependent effect sizes.
