ObjectiveTo estimate the level and evolving pattern of peptic ulcer disease (PUD) burden from 1990 to 2019. MethodsThe related data of PUD from 1990 to 2019 were obtained from GBD 2019 database. The corresponding age-standardized rate, annual percentage change, average annual percentage change were calculated and analyzed by Excel and R software. ResultsThe global standardized prevalence of PUD was 99.4/100 000 (95%CI 83.9 to 117.5) in 2019, and decreased from 143.4/100 000 (95%CI 120.5 to 170.2) in 1990. The standardized disability-adjusted disease years (DALYs) rate was 74.4 (95%CI 69.0 to 81.9) in 2019. The estimated annual percentage change (EAPC) from 1990 to 2019 was −3.47% (95%CI −3.58 to −3.37), indicating that the standardized DALYs rate was declining. The prevalence and DALYs of PUD increased with age. The standardized DALYs rate was higher in males than in females in the same age group. Sociodemographic index (SDI) was negatively correlated with the standardized prevalence of PUD (R=−0.45, P<2.2e−16) and the standardized DALYs rate (R=−0.79, P<2.2e−16). ConclusionThe worldwide burden of PUD declined from 1990 to 2019, but the decline had begun to slow or pause in countries with better economic development levels.
ObjectiveThis study intends to analyze the changing disease burden of mood disorders in China from 1990 to 2021 and project the epidemiological trends in the next two decades. MethodsThis study uses data from the Global Burden of Disease (GBD) 2021 database on three mood disorders in China (bipolar disorder, major depressive disorder, and dysthymia) from 1990 to 2021. The indicators such as age-standardized number of diseases and disability-adjusted life years (DALYs) were used to explore the characteristics of time, gender, and age distribution of the disease burden of mental disorders. The BAPC model was used to predict the disease burden in the next two decades. ResultsIn 2021, the number of cases of dysthymia, MDD, and BD in China was 27.84 million, 26.0 million, and 2.85 million, with an increase of 73.24%, 38.33%, and 36.79% compared with 1990, respectively. In 2021, DALYs of dysthymic disorder, MDD and BD were 2.67 million, 5.2 million and 0.61 million person-years, which increased by 71.45%, 34.29% and 34.76% compared with 1990, respectively. The burden of mood disorders is heavier among women and the middle-aged and elderly population. In addition, it is expected that ASPR and ASDR of dysthymia will continue to increase after a brief decline, MDD will show a downward trend, while BD will show a slight upward trend in the next two decades. ConclusionThe disease burden of mood disorders in China remains substantial, with dysthymia and BD showing persistent upward tendency. More resources should be invested in mental health care.
