Recently, sponsored by the Science Popularization Department of the China Anti Cancer Association, jointly organized by the Rehabilitation Branch of the China Anti Cancer Association and the Mijian Digital Cancer Patient Course Management Platform, and co-organized by the Science Popularization Special Committee of the China Anti Cancer Association, The "2022 White Paper on the Quality of Life of Chinese Lung Cancer Patients" has been officially released (herein after referred to as the "White Paper"), which mainly elaborates on the basic situation of Chinese lung cancer patients and the medical, social, and economic impacts caused by the disease. This article interprets the White Paper in order to help the public understand the real situation of lung cancer patients and provide important empirical evidence and valuable insights for the diagnosis, treatment, and rehabilitation of lung cancer in China.
ObjectiveTo provide reference for the formulation of public health policies through exploring the disease burden of aortic aneurysm (AA) in Chinese young adults. MethodsWe analyzed sex-specific mortality rates and years of life lost (YLLs) among Chinese young adults with AA in Global Burden of Disease (GBD) from 1990 to 2019, and compared with global and young adult AA data stratified by sociodemographic index (SDI). Joinpoint was used to analyze the time trend of AA burden among young males and females in China. The attributable risk factors for AA burden in young adults and its characteristics were analyzed. ResultsAmong young adults (15-39 years old) in China, the total of AA deaths in 2019 was 657 (95%UI 549-791), with an increase of 16.90% compared with 1990. The mortality rate in 2019 was 0.13 per 100 000 (95%UI 0.11-0.16), with an increase of 30.00% compared with 1990. In 2019, a total of 36921 YLLs (95%UI 30 865-44 445) were produced by young adults in China, with an increase of 13.21% compared with 1990. The YLLs rate in 2019 was 7.42 per 100 000 (95%UI 6.20-8.93), with an increase of 24.92% compared with 1990. The male YLLs rate was 11.49 per 100 000 (95%UI 9.22-14.28), with an increase of 35.18%. The female YLLs rate was 3.11 per 100 000 (95%UI 2.36-3.98), with a decrease of 3.12%. Both the AA mortality rate and YLLs rate in male young adults were higher than those in female young adults, and the growth rate from 1990 to 2019 was significantly higher than that in females. ConclusionThe disease burden of AA among young adults in China increases significantly from 1990 to 2019, mainly among males. The time trend of male and female AA YLLs in Chinese young adults is obviously inconsistent. The AA YLLs of Chinese male young adults are positively correlated with economic development and the progress of medical technology, and are in the process of gradual increase. The AA YLLs of Chinese female young adults are much lower than the average level, which is closely related to the low smoking rate.
ObjectiveTo analyze the disease burden and evolving trends for gastric cancer in China and worldwide from 1990 to 2021. MethodsBased on the 2021 Global Burden of Disease (GBD) database, we analyzed the burden of gastric cancer using indicators such as incidence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lost due to disability (YLDs). Joinpoint regression analysis was used to calculate the average annual percentage change (AAPC) of these indicators to show trends over time. ResultsIn 2021, the standardized incidence rate of gastric cancer was 14.33 (per 100 000) worldwide and 29.05 (per 100 000) in China, with corresponding standardized mortality rates of 11.20 (per 100 000) and 21.51 (per 100 000). The standardized incidence rate of gastric cancer in China trended downward during 1990–2021 (AAPC=–1.61%, P<0.05), but was lower than the global decline (AAPC=–1.77%, P<0.05). During 1990-2021 in China, the rates of standardized DALYs (AAPC=–2.76%, P<0.05), standardized YLLs (AAPC=–2.78%, P<0.05) and standardized YLDs (AAPC= –1.25%, P<0.05) all showed a significant decrease. The global rates of standardized DALYs (AAPC=–2.42%, P<0.05), standardized YLLs (AAPC=–2.44%, P<0.05) and standardized YLDs (AAPC=–1.56%, P<0.05) all showed a significant decrease. These AAPC values above indicated a general attenuation in the gastric cancer burden across all age groups, both in China and worldwide. ConclusionsDespite these signs of a decline in disease burden indicators for gastric cancer in China and worldwide, the number of cases and deaths in gastric cancer remains substantial coupled with the heavy burden on the healthcare system. Therefore, increased efforts in early detection and prevention strategies are of utmost importance to further reduce the impact of this malignant disease.
Objective To integrate and analyze the disease burden of esophageal cancer caused by alcohol consumption in China from 1990 to 2019, along with the differences between genders, and predict the trends in disease burden changes from 2020 to 2029 to improve prevention and treatment strategies. Methods The disease burden of esophageal cancer caused by alcohol consumption in China from 1990 to 2019 was extracted and integrated from the 2019 Global Burden of Disease (GBD) database, and the corresponding trend was analyzed using the Joinpoint regression model with Joinpoint 4.9.1.0 software. The gray prediction model [GM (1, 1) ] was used to forecast the disease burden of alcohol-related esophageal cancer in China from 2020 to 2029. Results In 2019, the leading causes of esophageal cancer in China were tobacco, alcohol, high body mass index, and insufficient fruit and vegetable intake, accounting for the first to fifth positions in esophageal cancer deaths. From a gender perspective, in 2019, the death number and standardized mortality rate for males were 18.97 times and 20.00 times higher than for females, respectively. The disability-adjusted life years (DALYs) and standardized DALYs rate for males were 33.08 times and 24.78 times higher than those for females, respectively, indicating a heavier disease burden of alcohol-related esophageal cancer among Chinese males. From 1990 to 2019, the average annual percentage change (AAPC) in deaths and DALYs due to alcohol-related esophageal cancer in China was 2.08% and 1.63%, respectively, showing a continuous upward trend with statistical significance (P<0.05). The AAPC values for standardized mortality rate and standardized DALYs rate from 1990 to 2019 were –0.92% and –1.23%, respectively, showing a continuous downward trend with statistical significance (P<0.05). The population aged ≥55 years was the main group bearing the disease burden among all age groups from 1990 to 2019. The gray prediction model predicted that by 2029, the overall standardized mortality rate and standardized DALYs rate would decrease to 2.94/100 000and 67.94/100 000, with a greater decline in females than in males. Conclusion Over the past 30 years, the disease burden of alcohol-related esophageal cancer in China has slightly decreased. However, the reduction in disease burden is still lower compared to the overall decline in esophageal cancer burden, and the disease burden for males is significantly higher than for females. Focusing on prevention and treatment for males and the elderly population remains a major issue in addressing alcohol-related esophageal cancer in China.
Objective To analyze the disease burden and trends of tracheal, bronchus, and lung cancer (TBL) attributable to occupational carcinogens in China from 1990 to 2021, in order to provide parameters for the prevention and control of TBL in China. Methods Based on the Global Burden of Disease database 2021, with occupational carcinogens as relevant risk factors and tracheal, bronchus, and lung cancer as the study diseases, data on mortality and disability-adjusted life years (DALYs) attributable to occupational carcinogens in China from 1990 to 2021 were extracted and age-standardized. Joinpoint regression models were used to calculate the annual percent change (APC) and average annual percent change (AAPC). Hiplot was used to visualize the distribution of disease burden by gender and age. The grey model GM (1, 1) was used to predict the disease burden and trends of TBL attributable to occupational carcinogens in China from 2022 to 2031. Results From 1990 to 2021, the overall mortality rate, DALYs rate, age-standardized mortality rate, and age-standardized DALYs rate of TBL attributable to occupational carcinogens in China increased from 1.85/100 000,53.93/100 000, 2.64/100 000, and 69.50/100 000 in 1990 to 5.22/100 000, 129.29/100 000, 3.49/100 000, and 83.80/100 000in 2021, respectively. The growth rates were 181.62%, 139.77%, 32.40%, and 20.59%, respectively. Joinpoint regression analysis showed that the AAPC values of overall mortality rate, DALYs rate, age-standardized mortality rate, and age-standardized DALYs rate of TBL attributable to occupational carcinogens in China from 1990 to 2021 were 3.41%, 2.87%, 0.92%, and 0.62%, respectively (all P<0.05), showing an overall upward trend, with higher values in females than in males. In 2021, the overall mortality rate of TBL attributable to occupational carcinogens in China gradually increased with age, with high mortality rates mainly concentrated in those aged>65 years, and higher rates in males than in females. The overall DALYs rate showed a trend of increasing first and then slowly decreasing with age, peaking at 65-74 years old, with higher rates in males than in females. The grey prediction model GM (1, 1) showed that the predicted values of mortality rate, DALYs rate, age-standardized mortality rate, and age-standardized DALYs rate of TBL attributable to occupational carcinogens in China from 2022 to 2031 all showed an upward trend. By 2031, the predicted values of mortality rate, DALYs rate, age-standardized mortality rate, and age-standardized DALYs rate will reach 7.19/100 000, 175.63/100 000, 4.16/100 000, and 93.64/100 000, respectively. Conclusion From 1990 to 2021, the mortality rate, DALYs rate, age-standardized mortality rate, and age-standardized DALYs rate of TBL attributable to occupational carcinogens in China all showed an upward trend. Males and the elderly are the main populations affected by the disease burden of TBL attributable to occupational carcinogens in China. It is necessary to strengthen the prevention and control of occupational carcinogens and promote health education.
Objective To assess the evolving disease burden of esophageal and gastric cancers in China from 1990 to 2021, with a focus on gender disparities, and construct a predictive model to forecast disease trends from 2022 to 2031, aiming to optimize targeted prevention strategies. MethodsEpidemiological data for esophageal and gastric cancers in China (1990-2021) were extracted from the Global Burden of Disease (GBD 2021) database. Temporal trends were analyzed using Joinpoint regression (version 4.9.1.0), and future trends were predicted via the GM (1,1) model under grey system theory. ResultsFrom 1990 to 2021, tobacco- and alcohol-attributable burdens of esophageal cancer increased, while tobacco- and diet-related burdens of gastric cancer declined. Deaths and disability-adjusted life years (DALY) for esophageal cancer rose by 26.38% and 17.89%, respectively; gastric cancer deaths increased by 18.95%, though DALY decreased by 1.22%. Both cancers exhibited significant declines in age-standardized mortality rates (−45.78% for esophageal cancer, −53.29% for gastric cancer) and age-standardized DALY rates (−51.36% for esophageal cancer, −57.58% for gastric cancer). Despite these reductions, China’s age-standardized mortality and DALY rates for both cancers remained consistently higher than global averages, with slower decline rates. Males exhibited disproportionately higher burdens than females. Predictive modeling projected continued but decelerating declines in disease burdens for both cancers by 2031. ConclusionOver three decades, China achieved measurable reductions in esophageal and gastric cancer burdens, though gastric cancer burdens remained higher than esophageal cancer. Persistent disparities relative to global levels, elevated male burdens, and aging demographics highlight the urgency for prioritized interventions targeting high-risk populations.
Objective To analyze the current status and temporal trends of the disease burden of spinal fractures in China from 1990 to 2021 based on data from the Global Burden of Disease Study 2021 (GBD 2021), aiming to provide evidence for developing prevention and treatment strategies. Methods Epidemiological data on spinal fractures in China, the United States of America (USA), and globally were extracted from the GBD 2021 database. Joinpoint regression models were applied to analyze temporal trends. Age-standardized incidence, prevalence, and disability-adjusted life years (DALYs) rates were calculated, with comparisons of gender- and age-group disparities. Results In 2021, the number of incident cases, prevalent cases, and DALYs of spinal fractures in China increased by 52.28%, 113.68%, and 106.98%, respectively, compared to 1990. The age-standardized incidence, prevalence, and DALYs rates rose by 11.80%, 16.11%, and 14.79%, respectively. The disease burden escalated significantly with age, peaking in individuals aged ≥75 years. Males exhibited higher age-standardized incidence and DALYs rates than females. Comparative analysis revealed that the age-standardized DALYs rate in China (4.19/100 000) was lower than that in globally (6.62/100 000) and USA (15.92/100 000). However, China showed an upward trend [annual average percentage change (AAPC)=0.19%], contrasting with a declining trend in the USA (AAPC=–0.08%). ConclusionThe escalating disease burden of spinal fractures in China is closely linked to population aging, gender disparities, and insufficient targeted prevention policies. Future strategies should integrate age- and gender-specific interventions, including strengthened osteoporosis prevention, trauma risk control, and big data-driven precision measures, to mitigate this burden.
ObjectiveTo systematically analyze the temporal trends of pancreatic cancer burden in globally and China from 1990 to 2021 using the Global Burden of Disease Study 2021 (GBD 2021) database and predict disease burden changes over the next 15 years. MethodsThe data of the incidence, death, disability-adjusted life years (DALYs) and age-standardized rate data of pancreatic cancer in GBD 2021 were extracted to analyze the epidemic status. Joinpoint regression models were employed to calculate average annual percentage changes (AAPC) and identify trend transitions. An auto-regressive integrated moving average (ARIMA) model was utilized to predict disease burden from 2022 to 2036. ResultsIn 2021, the global age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR) for pancreatic cancer were 5.96 (per 100 000), 5.95 (per 100 000), and 130.33 (per 100 000). Corresponding rates in China were 5.64 (per 100 000), 5.72 (per 100 000), and 137.23 (per 100 000). From 1990 to 2021, the average annual growth rate of ASIR (AAPC=0.72%), ASMR (AAPC=0.56%) and ASDR (AAPC=0.36%) were significantly higher than the global rate (ASIR: AAPC=0.27%; ASMR: AAPC=0.16%; ASDR: AAPC=0.02%). Age-specific analysis showed that the crude incidence, mortality, and DALYs rates for the population aged ≥60 years old in China (AAPC: 0.37%–1.55%) were all increasing at a higher rate than the same age group globally (AAPC: –0.02%–0.77%). Sex differences were significant, with greater disease burden in men than in women. ARIMA model predicted that Chinese and global ASIR and ASMR will continue to rise by 2036, with persistently steeper increases in males than females. ConclusionThe disease burden of pancreatic cancer in China is growing faster than that of the world, so early screening and prevention of pancreatic cancer should be strengthened.
ObjectiveTo analyze and compare the disease burden, trends, and influencing factors of lung cancer in adolescents and young adults (AYAs) in China and globally from 1990 to 2021, providing a reference for the prevention and treatment of lung cancer in China. MethodsIndicators of lung cancer disease burden in different genders and age groups in 204 countries or regions from 1990 to 2021 were retrieved and standardized from GBD 2021 database. The Joinpoint regression model was used to calculate the average annual percentage change (AAPC) of the standardized rates of lung cancer in AYAs in China and globally from 1990 to 2021; changes in incidence, mortality, and disability-adjusted life years (DALYs) rates due to population growth, aging, and epidemiological changes were analyzed; differences in lung cancer disease burden in AYAs in different socio-demographic index (SDI) regions were analyzed; and the influencing factors of lung cancer in AYAs in China and globally were explored. ResultsFrom 1990 to 2021, the age-standardized incidence rate (ASIR) (AAPC=−0.18%, P<0.001), age-standardized mortality rate (ASMR) (AAPC=−0.62%, P<0.001), and age-standardized DALYs rate (AAPC=−0.62%, P<0.001) of lung cancer in AYAs in China showed a downward trend, consistent with the global trend, but the decline in China was relatively small. During this period, the age-standardized rates of various indicators of lung cancer in males in China and globally were higher than those in females, and the burden of lung cancer in Chinese males was heavier. However, due to the significant downward trend in males, the gap in lung cancer burden between males and females was narrowing. At the same time, from 2013 to 2021, the ASIR [annual percent change (APC)=2.01%, P<0.001], ASMR (APC=1.46%, P<0.001), and standardized DALYs rate (APC=1.46%, P<0.001) in China showed an upward trend. From 1990 to 2021, among the main influencing factors for the incidence, mortality, and DALYs rates of lung cancer in Chinese AYAs, the contribution of aging was upward-pushing, while the increase in global indicators was mainly attributed to population growth. The global burden of lung cancer in AYAs was overly concentrated in high SDI regions. Although the gap in lung cancer burden between high SDI and low SDI regions was narrowing, it remained widespread. Globally, smoking, environmental PM2.5, insufficient fruit intake, second-hand smoke, and indoor air pollution were prominent risk factors. ConclusionFrom 1990 to 2021, the global and Chinese AYAs lung cancer incidence and mortality rates generally show a downward trend, but the female lung cancer burden relatively increases, especially in young women without a history of smoking. Continued efforts are needed to reduce the burden of lung cancer in AYAs, especially the specific risk for young women.
Objective To assess the burden of hypertensive nephropathy in China and the world from 1990 to 2021 and predict future trends. Methods Based on the Global Burden of Disease Database 2021, standardized prevalence, standardized mortality and standardized disability adjusted life year (DALY) rates were used to describe the burden of hypertensive nephropathy in China and the world from 1990 to 2021. Estimated annual percentage change (EAPC) and autoregressive integrated moving average model were used to reveal the trend of disease burden. Results From 1990 to 2021, the EAPCs of standardized prevalence, standardized mortality and standardized DALY rates of hypertensive nephropathy in China were −0.61% (−0.73%, −0.50%), −0.77% (−0.85%, −0.69%), and −1.00% (−1.09%, −0.91%), respectively. The global EAPCs for standardized prevalence, standardized mortality, and standardized DALY rates of hypertensive nephropathy were −0.16% (−0.18%, −0.13%), 0.97% (0.91%, 1.03%), and 0.63% (0.58%, 0.67%), respectively. The standardized prevalence rate, standardized mortality rate and standardized DALY rate of hypertensive nephropathy in China all showed a downward trend, and the global standardized prevalence rate also showed a downward trend, while the global standardized mortality rate and standardized DALY rate showed an upward trend, and the indicators of disease burden in China were lower than the global level. The standardized mortality rate and the standardized DALY rate of hypertensive nephropathy were higher in males than in females. With the increase of age, the disease burden indicators of hypertensive nephropathy in China and the world were on the rise, and the age of disease and death were concentrated in the age group over 65 years old. Renal dysfunction and hypertension were important risk factors for death in hypertensive nephropathy patients. It was estimated that from 2022 to 2040, the standardized prevalence rate and mortality rate of hypertensive nephropathy would be on the rise in China and the world, and the standardized DALY rate would be on the rise in the world, while in China it would be on the decline. Conclusions The burden of hypertensive nephropathy is heavy in China and the world from 1990 to 2021, and the control of hypertension and prevention of renal dysfunction should be strengthened. It is estimated that the standardized prevalence and mortality of hypertensive nephropathy will increase in China and the world from 2022 to 2040, and the disease burden will remain heavy.
