Article Abstract
Background: Few studies have focused on the descriptive epidemiology and trends of HIV/AIDS since the publication of the Global Burden of Disease (GBD) study in 2021. Therefore, this study aims to analyze the trends and patterns of the HIV/AIDS burden at the global, regional, and national levels by sex, age and social development index (SDI). We also explored risk factors and predicted the GBD of HIV/AIDS until 2030.
Methods: Data on the etiology of HIV/AIDS from 1990 to 2021 were collected from the 2021 GBD database. Estimated annual percent changes (EAPCs) were calculated to assess temporal trends in the age-standardized incidence rate (ASIR), age-standardized disability-adjusted life-year rate (ASDR) and age-standardized mortality rate (ASMR) of HIV/AIDS patients. Measures categorized by sex, region, age and SDI quintiles. In addition, an age‒period‒cohort model was established to forecast future trends of the HIV/AIDS burden to 2030.
Results: Globally, the incidence of HIV/AIDS reached 1.65 million (95% uncertainty interval 1.48 to 1.82) in 2021. From 1990 to 2021, the global ASIR of HIV/AIDS showed a downward trend, with an EAPC of 0.14% (0.12-0.16%). The ASIR, ASDR, and ASMR of HIV/AIDS were highest in the low-SDI region and lowest in the high-SDI region. Regionally, southern sub-Saharan Africa had the highest ASIR in 2021, whereas Oceania had the largest increase in the ASIR from 1990 to 2021. Burundi (EAPC 14.04%, 95% CI -13.63 to -14.44%), followed by Burkina Faso, exhibited the most significant decrease in the ASIR. Globally, the highest incidence rate was observed in the 25-29 years old group. Unsafe sex is the primary factor leading to the burden of HIV/AIDS. By 2030, the global ASIR, ASDR and ASMR of HIV/AIDS are expected to gradually decrease.
Conclusion: HIV/AIDS disease burden varies by region, sex, and age. The global burden of HIV/AIDS is substantial in low-income regions, especially in Sub-Saharan Africa. Our study offers valuable epidemiological evidence for future research on the prevention and treatment of HIV/AIDS.

Background: Major depressive disorder (MDD), anxiety disorders, and self-harm are substantial contributors to the global disease burden, exacerbated by the COVID-19 pandemic.
Methods: We used Global Burden of Diseases Study (GBD) 2021 to estimate global, regional, and national prevalence, mortality, and disability-adjusted life years (DALYs) for MDD, anxiety disorders, and self-harm from 1990 to 2021. Annual percentage changes were calculated for pre-pandemic (1990-2019) and pandemic (2019-2021) periods.

Background: Antiretroviral therapy has extended the lifespan of HIV/ADIS. However, research and policies mainly target younger groups, leaving gaps in the care for aging people living with HIV (PLHIV).
Methods: Using data from the 2021 Global Burden of Disease Study, this research evaluated the global, regional, and national burdens of HIV/AIDS in adults aged 60 and above from 1990 to 2021.

Using the Global Burden of Disease (GBD) 2021 database, this study analyzed temporal, spatial, and population-specific trends in lead-attributable IDD burden among global children/adolescents (1990-2021) and projected trends to 2040 to inform global public health strategies. GBD 2021 data characterized global, regional, and national distributions of lead-attributable IDD burden.

Purpose: This study aims to systematically quantify the global burden of osteoarthritis (OA) in women of childbearing age (WCBA) and analyze its temporal trends and regional disparities.
Methods: This study utilized the Global Burden of Disease 2021 data to assess the incidence and years lived with disability (YLDs) spanning from 1990 to 2021. The Bayesian age-period-cohort (BAPC) model was adopted to forecast trends up to 2045.
