Distribution of edentulism by the macro determinants of health in 204 countries and territories

Abstract

Objective

To carry out a comprehensive description of edentulism estimates by the macro determinants of health in 2000, 2010 and 2019 worldwide.

Methods

This ecological study analyzed data from the Global Burden of Disease Study (GBD) to describe the incidence rate, prevalence rate and years lived with disability (YLDs) rate due to edentulism by macro determinants of health (governance, macroeconomic policy, social policy, public policies, societal values), for 204 countries and territories. The estimates were reported as rates (cases/100,000 people), for people of both sexes aged 55 years or older.

Results

Countries belonging to the least privileged categories of the macro determinants showed the lowest prevalence rate, incidence rate, and YLD rate due to edentulism for all exposures. Countries with low government expenditure on health showed the lowest prevalence rate of edentulism in 2000 (18,972.1; 95 %CI 15,960.0 - 21,984.3) and 2010 (16,646.8; 95 %CI: 14,218.3–19,075.4) than those with high government expenditure on health in 2000 (25,196.6; 95 %CI: 23,226.9 - 27,166.2) and 2010 (21,014.7; 95 %CI: 19,317.9 - 22,711.5). Countries with low SDI showed the lowest YLDs in 2000 (321.0, 95 %CI: 260.1- 381.9), 2010 (332.0; 95 %CI: 267.7–396.3), and 2019 (331.6; 95 %CI: 266.6–396.5).

Conclusion

The findings point to persistent inequalities in the distribution of edentulism between countries worldwide. The most privileged countries, with higher economic development, better governance, and better social and public policies, have shown higher rates of edentulism.

Clinical Significance

This model must be reconsidered by advancing toward upstream and midstream strategies, beyond its conventional downstream clinical interventions.
