Global patterns in vision loss burden due to vitamin A deficiency from 1990 to 2017.

ABSTRACT:

Objective

To investigate the vision loss burden due to vitamin A deficiency (VAD) at the global, regional and national levels by year, age, sex and socio-economic status using prevalence and years lived with disability (YLD).

Design

International, retrospective, comparative burden-of-disease study.

Setting

Prevalence and YLD data were extracted from the Global Burden of Disease (GBD) Study 2017. The association of age-standardised YLD rates and human development index (HDI) was tested by Pearson correlation and linear regression analyses. The Gini coefficient and concentration index (CI) were calculated to demonstrate the trends in between-country inequality in vision loss burden due to VAD.

Participants

All participants met the GBD inclusion criteria.
