 This systematic review and meta-analysis aim to quantify and understand prevalence variation of elder abuse at the global and regional levels. The study included 52 studies from 28 countries, with a pooled prevalence rate for overall elder abuse of 15.7%. The study found that financial abuse had the highest prevalence estimate, while sexual abuse had the lowest. Meta-analysis revealed heterogeneity in studies that included overall abuse and significant associations were found between overall prevalence estimates and sample size, income classification, and method of data collection. Elder abuse affects one in six older adults worldwide, which is roughly 141 million people. The study highlights the need for more robust prevalence studies in low-income and middle income countries, and emphasises that elder abuse is a neglected global public health priority.
