Background: We estimated the global burden of ovarian cancer (OC) in 194 countries and territories between 2007 and 2017. Methods: Data were extracted from the Global Burden of Disease (GBD), Injuries, and Risk Factors 2017 study. Results: Globally, 286 126.80 (95% UI = 278 075.38-295 311.41) incident cases, 4.67 million (4.53-4.83) disability-adjusted life-years (DALYs), and 175 981.99 (171 384.15-181 198.43) deaths were reported in 2017. The age-standardized incidence and DALY rates increased by 2.05% and 1.34% during 2007-2017, respectively, while the age-standardized mortality rate decreased by À0.14%. The age-standardized incidence, DALY, and mortality rates in 2017 were the highest in the high socio-demographic index (SDI) quintile, but the largest percentage increase during 2007-2017 was in the low-SDI quintile. Among regions, Central Europe showed the highest 2017 age-standardized incidence, DALY, and mortality rates, whereas South Asia and East Asia showed the largest percentage increases in both rates during 2007-2017. Among countries, India showed the largest percentage increase in age-standardized incidence and DALY rates, whereas Iran showed the largest percentage increase in age-standardized mortality rates. Globally, the largest percentage increase in risk-attributable DALYs was associated with metabolic risk factors (e.g., high fasting plasma glucose levels). Conclusion:The global age-standardized incidence, DALYs, and mortality rates of OC remain stable during 2007-2017. However, the low SDI quintile and the greatest burden in South and East Asia, India, and Iran suggested that more targeted strategies should be performed in those regions and countries.

Background: We aimed to estimate the incidence, mortality, disability-adjusted life years (DALYs) for chronic obstructive pulmonary disease (COPD) in 204 countries and territories. We examined the variations in these trends by country, gender, age group, and sociodemographic index (SDI).Methods: We calculated the estimated annual percentage changes (EAPCs) to assess temporal trends in the age-standardized incidence rate, age-standardized mortality rate, and age-standardized DALYs of COPD from 1990 to 2019.Results: From 1990 to 2019, the COPD incidence and COPD-associated deaths and DALYs increased worldwide by 86%, 30%, and 26%, respectively. From 1990 to 2019, the global age-standardized incidence rate (EAPC, −0.11; 95% confidence interval (CI), −0.25 to 0.04), age-standardized mortality rate (EAPC, −2.10; 95% CI, −2.19 to −2.00), and age-standardized DALYs (EAPC, −1.87; 95% CI, −1.94 to −1.81) of COPD decreased. The age-standardized incidence of COPD increased most in areas with high SDI (EAPC 0.56). The largest increases in the age-standardized incidence rate of COPD were recorded in High-income North America (EAPC, 1.41), Southern Latin America (EAPC, 0.29), and North Africa and the Middle East (EAPC, 0.09). The three countries that recorded the largest increases in COPD incidence from 1990 to 2019 were the United States of America (EAPC, 1.51), Saudi Arabia (EAPC, 1.17), and Oman (EAPC, 1.10).Conclusion: Despite the decreased burden of COPD globally from 1990 to 2019, the age-standardized incidence rate of COPD increased in areas with high SDI, High-income North America, Southern Latin America, North Africa, and the Middle East.

Objective To report the global burden of maternal disorders and their main subcategories in 195 countries and territories between 2007 and 2017. Methods The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimated maternal disease burden at global, regional, and country levels. Maternal disorders were disaggregated into 10 categories, and estimated incidence and disability‐adjusted life years (DALYs) of maternal disorders were reported separately. Indicators were estimated in different geographic settings and different sociodemographic index (SDI) regions. Based on GBD 2017 estimates, we systematically examined the incidence and DALYs of maternal disorders and their main subcategories at the global, regional, and national levels during the period from 2007 to 2017 by age and SDI. Results Globally, a total of 7.98 million maternal disorders occurred in 2017, with a 4.33% (95% uncertainty interval [UI] 3.24%–5.60%) decrease in age‐standardized incidence rate and a more significant decrease (30.26%) in the age‐standardized rate of DALYs. Most incidences and DALYs were found in low‐income and middle‐income countries, especially in the sub‐Saharan region. The greatest incidence of maternal disorders was found to be in maternal abortion and miscarriage (2.00 million), and the highest disease burden was in maternal hemorrhage (2.23 million). Conclusion A slight increase in the incidence of maternal disorders and substantial reductions in DALYs of overall maternal disorders and their main subcategories were found from 2007 to 2017, especially in low‐income countries and the sub‐Saharan region. Maternal hemorrhage, hypertensive disorders, and indirect maternal death were the top three causes of maternal disorders disease burden.
