measurementBetween 1990 and 2021, the greatest substantial decline in the age-standardized incidence rate (ASIR) of nutritional deficiencies occurred in sub-Saharan Africa, with an estimated annual percentage change (EAPC) of -2.81 (-3.01 to 2.62).

measurementBetween 1990 and 2021, the Estimated Annual Percentage Change (EAPC) for the incidence rate of nutrient deficiency disorders was -2.52% (95% UI: -2.67%, -2.38%).

measurementBetween 1990 and 2021, South Asia had the lowest age-standardized disability-adjusted life expectancy (DALY) incidence of nutritional deficiencies, with an estimated annual percentage change (EAPC) of -6.17 (95% UI: -7.52–4.8).

measurementBetween 1990 and 2021, the Estimated Annual Percentage Change (EAPC) for the DALYs rate of nutrient deficiency disorders was -2.52% (95% UI: -2.71%, -2.32%).

measurementBetween 1990 and 2021, the age-standardized incidence rate (ASIR) of nutritional deficiencies in Australia trended higher, with an estimated annual percentage change (EAPC) of 0.03 (-0.18–0.24).

measurementBetween 1990 and 2021, the age-standardized death rate (ASDR) of nutritional deficiencies declined the most in East Asia, with an estimated annual percentage change (EAPC) of -8.07 (95% UI: -10.13–5.97).

procedureIn the study 'Analysis of study Global Burden of Disease in 2021', trends were recognized as a decrease when the upper boundary of the 95% confidence interval (CI) of the Estimated Annual Percentage Change (EAPC) was < 0; upward trends were defined when the lower boundary of the 95% CI of EAPC was > 0; otherwise, trends were defined as stable.

measurementBetween 1990 and 2021, the Estimated Annual Percentage Change (EAPC) for the prevalence rate of nutrient deficiency disorders was -0.98% (95% UI: -0.99%, -0.96%).

measurementBetween 1990 and 2021, the Estimated Annual Percentage Change (EAPC) for the mortality rate of nutrient deficiency disorders was -4.41% (95% UI: -4.84%, -3.98%).

measurementThe correlation between Age-Standardized Incidence Rate (ASIR) and Estimated Annual Percentage Change (EAPC) for nutritional deficiencies shifted from a significant negative correlation in 1990 (R = −0.29, P < 0.001) to a blurred relationship by 2021 (R = 0.03, P = 0.07).

claimThe Estimated Annual Percentage Change (EAPC) is an indicator used to track the trend of morbidity, incidence rate, and other indicators within a specific time period, calculated based on a regression model.
