(P17-048-25) Analysis of Changes in the Burden of Nutritional Deficiencies in China, the G20, and Globally From 1990 to 2021 Based on the Global Burden of Disease 2021 Data

Objectives: Nutritional deficiency has recently received considerable attention as a significant risk factor affecting global health. This study analyzed the burden and trend of nutritional deficiencies in China, the global and G20 regions, from 1990 to 2021 based on age and gender, and used this burden analysis, to evaluate the changes in their burden to guide future public health policies.

Methods: This study utilized data from the global burden of disease database (GBD) for 2021, on the prevalence and years lived with disability (YLDs) attributed to nutritional deficiencies in China, the global and G20 regions from 1990 to 2021. We analyzed the burden and temporal trends of nutritional deficiency and used estimated annual percentage change to reflect disease trends. Subsequently, we utilized relevant cutting-edge technologies to predict the trends of nutritional deficiencies in China and global regions for 2035.

Results: The burden of nutritional deficiencies in China, the global and G20 regions, demonstrated a significant declining trend from 1990 to 2021. China, the global and G20 regions had more male patients with nutritional deficiencies in the < 5 age group than female patients, while the proportion of female patients was higher than that of males in other age groups. Furthermore, dietary iron deficiency accounted for most of the nutritional deficiency cases, contributing the largest share of the burden. From 1990 to 2021, epidemiological changes were the primary driver of the increased disease burden of nutritional deficiencies in China. Population growth has been the primary driver of the increased disease burden of global nutritional deficiency.

Conclusions: The disease burden of nutritional deficiencies in China, the global and G20 regions, demonstrated a decreasing trend from 1990 to 2021. This may be associated with socioeconomic advancement. Regarding gender and age, this is associated with social factors, including poverty and social inequality. Regarding diseases, this may be linked to regional differences and dietary patterns in different regions.
