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 estimate the population attributable disease burden (PAD) of low bone mineral density (LBMD) related fractures (fragility fractures) among Chinese people over 50 years old from 1990 to 2023, using data from the Global Burden of Disease Study 2023 (GBD 2023), and to provide evidence for prevention strategies and health resource allocation. Methods? Based on the GBD 2023, the LBMD summary exposure values (SEV), fracture incidence, years lived with disability (YLDs), and LBMD-related falls YLDs of Chinese people over 50 years old from 1990 to 2023 were extracted. PAD was calculated with population attributable fraction (PAF), and an entropy-weight method was applied to evaluate the contribution of individual fracture sites. Temporal trends and sex differences were examined with Joinpoint regression. Results?From 1990 to 2023, the age-standardized SEV of LBMD in people over 50 years old showed an overall decline [average annual percent change (AAPC)=?0.564%]. Age-standardized fracture incidence, fracture YLDs rate, and LBMD-related falls YLDs rate all exhibited W-shaped upward trends (AAPC=1.045%, 0.296%, and 0.724%, respectively). PAF-based estimates indicated that LBMD-attributable fracture incidence likewise increased in a “W-shaped” manner (AAPC=0.558%), whereas the corresponding YLDs rate showed an overall W-shaped decline (AAPC=?0.193%). In international comparison, China and the global average displayed broadly concordant directions of change, with greater volatility in China and a progressive narrowing of the gap after 2015. Regarding sex differences, fracture YLDs rates were consistently higher in the males, whereas the other burden indicators were higher in the females; the temporal patterns were similar in both sexes. Entropy weight method identified hip fractures as contributing most to incidence (weight 0.133), and pelvic fractures as the largest contributor to YLDs rate (weight 0.115). ConclusionSince 1990, the LBMD attributable fracture burden in China’s older population has risen, with female and hip or pelvic fractures bearing the heaviest load. Strengthened osteoporosis screening, improved insurance coverage, and targeted health education are urgently needed to curb further increases in disease burden.
Objective To analyze the current status and temporal trends of the disease burden of osteoarthritis (OA) in China from 1990 to 2023, stratified by anatomical sites (knee, hip, hand, and other), utilizing data from the 2023 Global Burden of Disease (GBD) study, and to explore the site-specific heterogeneity of disease burden attributed to high body mass index (BMI), providing a scientific basis for formulating precision prevention and control strategies.Methods Based on the GBD 2023 database, data on the incidence, prevalence, and years lived with disability (YLDs), as well as their corresponding age-standardized rates of OA in China from 1990 to 2023, were collected and stratified by gender, age, and anatomical site (knee, hip, hand, and other). A log-linear regression model was employed to calculate the estimated annual percentage change (EAPC) to analyze temporal trends. Additionally, the population attributable fraction (PAF) was used to quantify the contribution of high BMI to OA across different sites and to analyze the heterogeneity of this attribution. Results In 2023, the disease burden of OA in China increased. In terms of anatomical distribution, knee OA constituted the heaviest burden, with 115.0032 million prevalent cases, accounting for approximately 65.78% of the total. Attribution analysis showed that knee OA was slightly more affected by high BMI than hip OA, and the PAF increased significantly over time. In 2023, the PAFs for knee and hip OA in females (29.49% and 28.57%, respectively) were substantially higher than those in 1990 (19.10% and 18.38%). A similar upward trend was observed in males (26.65% and 25.92% in 2023). Regarding attribution differences, female PAF levels were consistently higher than those of males across all years and sites. Hand OA exhibited the fastest growth rate, with the EAPC of its age-standardized YLDs rate reaching 1.64%, far exceeding that of knee OA (0.43%). Demographically, all burden indicators were higher in females than in males. Hand OA demonstrated an intergenerational cumulative effect. The difference in YLDs rates between 2023 and 1990 widened with age, reaching 123.29 per 100 000 in the >95 years old group, highlighting the severe challenges posed by population aging. Conclusion From 1990 to 2023, the disease burden of OA in China continued to rise. Knee OA remains the heaviest burden category and is significantly driven by high BMI, whereas hand OA shows the fastest growth trend. Prevention and control strategies should focus on weight management for knee and hip OA, while prioritizing the prevention and care of hand OA in the elderly population.
Objective To analyze the trends in the burden of intracerebral hemorrhage (ICH) and its related risk factors in China from 1990 to 2021, providing evidence for targeted prevention and control. Methods Based on public data from the Global Burden of Disease Study 2021, four epidemiological indicators, including incidence, prevalence, deaths, and disability-adjusted life-years (DALYs) were selected to describe the burden of ICH in China in 2021. Change rates and estimated annual percentage changes (EAPC) were calculated to evaluate the trends in disease burden from 1990 to 2021. The Das Gupta method was used to decompose the effects of population growth, population aging and epidemiological changes on the burden during this period. Finally, the attributable burden of risk factors related to ICH was analyzed. Results In 2021, the age-standardized incidence, prevalence, mortality, and DALY rates of ICH in China were 61.2/100000, 222.1/100000, 68.8/100000, and 1351.6/100000, respectively, all higher than global estimates. From 1990 to 2021, although these rates showed a declining trend (EAPC: ?2.24, ?1.26, ?2.38, and ?2.47, respectively), the absolute disease burden, including the absolute number of incidence cases, prevalence cases, deaths, and DALYs, continued to rise, with an increase ranging from 20.57% to 51.59%. In addition, the burden of ICH in China varied by age and sex, with older adults and males experiencing a higher burden. Decomposition analysis indicated that population aging and growth were the primary drivers of the increasing ICH burden in China, while epidemiological changes mitigated this trend. Metabolic factors were the predominant attributable risk factors for ICH. High systolic blood pressure, ambient particulate matter pollution, and diet high in sodium were important risk factors common to both genders. The DALY burden attributable to smoking and alcohol use was higher in men, whereas impaired kidney function and secondhand smoke had a greater impact on women. Conclusions The burden of ICH in China has continued to increase from 1990 to 2021, and it may further escalate in the context of population aging. Risk factor control remains a key priority for prevention. Future strategies should incorporate age- and sex-specific interventions to reduce the ICH burden in China.
ObjectiveTo analyze the epidemiological characteristics and trends of gallbladder cancer incidence and mortality in Zhejiang cancer registration areas from 2000 to 2021, providing a basis for formulating prevention and control strategies for gallbladder cancer. MethodsData on incidence and mortality were collected from 22 cancer registry areas in Zhejiang Province from 2000 to 2021, calculating the crude incidence (mortality), age-standardized incidence / mortality rate by Chinese standard population(ASR China), age-standardized incidence /mortality rate by World standard population (ASR World) and cumulative rate (0–74 years old). The average annual percentage change (AAPC) was calculated by using Joinpoint software. ResultsIn 2021, the crude incidence of gallbladder cancer in Zhejiang cancer registration areas was 6.79 per 100 000. The ASR China and ASR World were 2.99 and 2.96 per 100 000, respectively, ranking 18th of all new cancer cases. The incidence ASR China in female (3.13 per 100 000) was higher than that in male (2.85 per 100 000). The incidence ASR China in rural areas (3.01 per 100 000) was slightly higher than that in urban areas (2.97 per 100 000). The crude mortality of gallbladder cancer was 5.14 per 100 000, with the mortality ASR China and ASR World of 2.09 and 2.10 per 100 000, respectively, ranking 10th of all new cancer deaths. The mortality ASR China in female (2.19 per 100 000) was higher than that in male (1.98 per 100 000). The mortality ASR China in urban areas (2.11 per 100 000) was slightly higher than that in rural areas (2.07 per 100 000). Both the crude incidence and mortality of gallbladder cancer increased with age. The crude incidence and mortality showed an upward trend over time, with AAPC of 2.59% and 3.75%, respectively (P<0.001). The incidence ASR China did not show significant changes over time (AAPC=0.05%, P=0.856). The incidence ASR China in male and rural areas showed increasing trends over time, with AAPCs of 0.89% (P=0.016) and 1.14% (P=0.001), respectively. The incidence ASR China in female and urban areas showed no significant trends over time, with AAPCs of –0.26% (P=0.503) and –0.02% (P=0.967), respectively. The mortality showed a slower upward trend after adjusting the age structure (AAPC=1.01%, P=0.020). ConclusionsThe elderly population in rural areas, especially elderly women, are the primary targets for the prevention and control of gallbladder cancer. Aging is the main factor contributing to the increase in the incidence and mortality of gallbladder cancer. After adjusting for demographic factors, the overall upward trend of the incidence in the male population and rural areas, as well as mortality, cannot be ignored.
Objective To analyze the current status and trends in the burden of musculoskeletal diseases in China from 1990 to 2023, providing evidence-based support for formulating and optimizing prevention and control strategies for musculoskeletal diseases in China. Methods Based on the 2023 Global Burden of Disease (GBD) study database, the study integrated incidence, prevalence, disability-adjusted life years (DALYs), and age-standardized rates of musculoskeletal diseases in the Chinese population from 1990 to 2023, stratified by gender and age. The proportional contribution to all-cause prevalence was calculated, and regression models were constructed using Joinpoint software to assess temporal trends. ResultsIn 2023, the five major musculoskeletal diseases collectively accounted for approximately 25.0% of all-cause prevalence in China. Among these, osteoarthritis contributed the most (11.68%), followed by low back pain (6.89%) and neck pain (3.52%). Gout (1.28%) and rheumatoid arthritis (0.36%) had relatively lower contributions. From 1990 to 2023, the overall burden of the five major musculoskeletal diseases remained substantial, with heterogeneous temporal patterns across diseases. Stratified by age and gender, the five diseases exhibited low levels during childhood and adolescence, increased significantly in middle and older adulthood, and peaked in the elderly. Except for gout, the burden of the other four diseases was higher in females than in males across most age groups. The scale of each disease varied considerably. Osteoarthritis showed the most significant increase in prevalence, with prevalent cases increasing from 53.7668 million to 161.7424 million, and the age-standardized DALYs rate rising by 16.19%. Gout showed the fastest growth in disease burden, with age-standardized DALYs rates rising from 19.88/100 000 to 25.14/100 000 (a 26.46% increase). Although low back pain showed a decline, it remained a major source of disability over the long term, with the age-standardized DALYs rate decreasing from 740.83/100 000 to 551.92/100 000 (a 25.49% decrease). Neck pain remained generally stable with a age-standardized DALYs rate increase of 1.18%. The age-standardized incidence rate of rheumatoid arthritis increased by 19.41%, and the age-standardized DALYs rate decreased by 8.38%.Conclusion Over the past 30 years, the burden of musculoskeletal diseases in China has shown a persistent upward trend with significant gender and age disparities. Future prevention and control strategies should place greater emphasis on early identification and proactive interventions, advocating for more targeted comprehensive measures for high-risk populations. Concurrently, efforts must be made to enhance standardized diagnosis and treatment capabilities at the primary care level, alongside strengthening continuous rehabilitation management.
ObjectiveTo analyze the current status and trends of the disease burden of knee osteoarthritis (KOA) in China from 1990 to 2023, and to examine the epidemiological characteristics of age, gender differences, and attribution to high body mass index (BMI), in order to provide a basis for formulating prevention and treatment strategies to reduce the disease burden of KOA in China. Methods Based on the 2023 Global Burden of Disease Study (GBD) database, data on the number, rate, and age-standardized rate of incidence, prevalence, disability-adjusted life years (DALYs) for KOA, and DALYs for KOA attributable to high BMI in the Chinese population from 1990 to 2023 were integrated. The Joinpoint 5.4.0.0 software was used to analyze the age and gender differences in KOA and the epidemiological characteristics attributable to high BMI. Results The standardized incidence, prevalence, and DALYs rates of KOA in China in 2023 increased by 6.46%, 6.43%, and 6.93%, respectively, compared with 1990. In terms of age, the disease burden of KOA in China was lowest in the age group of 30-34 years, with the highest incidence rate in the age group of 50-54 years, whereas the prevalence rate and DALYs rate continued to increase with age, and both were highest in the age group of ≥70 years. In terms of gender, all disease burden standardized rate indicators were higher in females than in males, and the difference widened with age. The rate of BMI-attributable DALYs increased at an annual average rate of 1.57% (95%CI: 1.55, 1.59) from 1990 to 2023, again with significant age and gender differences. ConclusionThe continued growth of the KOA disease burden and significant population differences characterizing China call for focused attention on the female middle-aged and elderly population, enhanced weight management, and implementation of targeted preventive and control measures.
The present paper is to evaluate the scientific research level and development trends of biomedical engineering in China using metrology analysis on Chinese biomedical engineering scientific literatures. Pubmed is used to search the biomedical engineering publications in recent 5 years which are indexed by Science Citation Index, and the number and cited times of these publications and the impact factor of the journals are analyzed. The results show that comparing with the world, although the number of the publication in China has increased in recent 5 years, there is still much room for improvement. Among Chinese mainland, Hongkong and Taiwan, Chinese mainland maintains the obvious advantage in this subject, but Hongkong has the highest average cited number. Shanghai and Beijing have better research ability than other areas in Chinese mainland.
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.
Objective To analyze the trends in the disease burden of fall-related fractures among elderly Chinese from 1990 to 2023, and to examine the disparities by age, gender, and fracture site, in order to inform the development of targeted strategies for the prevention of such fractures. Methods Data on the incidence, prevalence, and years lived with disability (YLDs) of fall-related fractures among elderly Chinese from 1990 and 2023 was sourced from the 2023 Global Burden of Disease (GBD) study. The disease burden across age groups, genders, and fracture sites was assessed. Furthermore, temporal trends by these strata were analyzed using Joinpoint 5.4.0.0 software. Results From 1990 to 2023, the average annual percent changes in the age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), and age-standardized years of life lost rate (ASYR) for fall-related fractures among elderly Chinese were 1.81%, 1.03%, and 0.83%, respectively. In China, the disease burden of fall-related fractures among the elderly increased with advancing age, and the rate of this increase accelerated in older age groups. Females had higher values than males in terms of ASIR, the rates of increase for all burden measures were greater in males. Fall-related fractures among the elderly Chinese can be classified into 12 sites, among which hip fracture had the highest ASIR, with values of 538.15 and 963.57 per 100 000 in 1990 and 2023, respectively. Fractures of the patella, tibia, fibula, or ankle had the highest ASPR and ASYR. Their ASPR were14 836.73 and 19 727.74 per 100 000 in 1990 and 2023, respectively, and ASYR were 740.84 and 989.54 per 100 000, respectively. Conclusion The increasing and heterogeneous burden of fall-related fractures among elderly Chinese calls for targeted management strategies, in addition to enhanced osteoporosis prevention, that address the distinct risks by gender, age, and fracture site.
