The Impacts of Health Insurance and Resource on the Burden of Alzheimer's Disease and Related Dementias in the World Population

Introduction The increasing prevalence of Alzheimer's disease and related dementias (ADRD) presents both a burden and an opportunity for intervention. This study aims to estimate the impacts of health insurance and resources on the burden attributed to ADRD. Method Data were mainly collected from global databases for ADRD. Analysis of variance, Pearson correlation, random-effects, and fixed-effects model analyses were used in this study. Results Although the current medical expenditures were increasing and out of pocket (OOP) expenditures were declining generally in various countries, the collected global data showed an increased burden of ADRD on patients both physically and economically. Furthermore, health resources were negatively associated with disability-adjusted life years (DALY), death, and years of life lost (YLL), but were otherwise positively associated with years of life lived with disability (YLD). Discussion Effective measures should be considered to cope with the rising burden. Meanwhile, there is an urgent call for constructive and sustainable rational plans and global collaboration. Highlights We explored how health insurance and resources affect Alzheimer's disease and related dementias (ADRD)-related burden. Health insurance and resources were imbalanced among four income level groups. Health insurance and resources may decrease the total ADRD burden primarily from a reduction in death-related burden. Health insurance and resources may increase disability-related burden.
