Global, regional, and national burdens of common micronutrient deficiencies from 1990 to 2019: A secondary trend analysis based on the Global Burden of Disease 2019 study.

ABSTRACT:

Background

Understanding micronutrient deficiency burdens and trends can help guide effective intervention strategies. This study aims to elucidate trends in common micronutrient deficiencies, in particular, dietary iron, iodine and vitamin A deficiencies, from 1990 to 2019 using Global Burden of Disease (GBD) 2019 study data.

Methods

We analyzed data from the GBD 2019 study to calculate the prevalence, incidence, and disability-adjusted life year (DALY) rates of micronutrient deficiencies in geographic populations worldwide from 1990 to 2019. The estimated annual percentage changes (EAPCs) and age-standardized rates were calculated to evaluate the temporal trends.

Findings

Globally, the age-standardized prevalence rates of iodine deficiency, vitamin A deficiency, and
