ObjectiveTo analyze the disease burden of prostate, bladder and kidney cancers attributable to smoking in China from 1990 to 2019. MethodsBased on the global burden of disease study 2019, the current situation of the disease burden of prostate, bladder and kidney cancers attributable to smoking was analyzed by using the population attributable fraction (PAF), deaths and disability-adjusted life years (DALYs). Furthermore, the annual percent change (APC) and the average annual percent change (AAPC) were calculated by joinpoint regression analysis to describe the long-term trends of the smoking-attributable burden of these three cancers from 1990 to 2019. ResultsThere were an estimated 18 800 cases of deaths and 393 106 person-years of DALYs for bladder cancer caused by smoking in 2019. The age-standardized mortality and DALY rate decreased by 0.41% and 0.39% per year from 1990 to 2019, respectively. For prostate cancer, smoking was estimated to have caused 5 016 cases of deaths and 98 276 person-years of DALYs in 2019. The age-standardized mortality and DALY rate decreased by 0.28% and 0.25% per year from 1990 to 2019, respectively. For kidney cancer, the deaths and DALYs attributable to smoking were 4 935 cases and 120 620 person-years, respectively. The standardized mortality and DALY rates increased by 3.03% and 2.98% per year from 1990 to 2019. Additionally, males suffered from a higher disease burden of these three cancers attributable to smoking than females. The elderly population had a higher smoking-attributable disease burden than the younger population. ConclusionThe situation of the disease burden of bladder, prostate and kidney cancers attributable to smoking is still serious in China, which has substantial disparities in different groups. Specifically, males and the elderly are the high-risk groups for the smoking-attributable burden. Among the three cancers, bladder cancer has the highest burden and kidney cancer has the largest burden increase during 1990-2019.
ObjectiveThe aim of this study was to assess the disease burden of non-COVID-19 lower respiratory infection (LRI) in China during the period 1990−2021, particularly during the period 2019−2021. MethodsData on the burden of disease for LRI in China were obtained from the GBD 2021 database. A Joinpoint regression model was used to describe the changes in disease burden trends of LRI in China from 1990 to 2021, and the results are presented in terms of average annual percentage change (AAPC). ResultsIn 2021, the age-standardized incidence rate of LRI in China was 2 853.31/100 000, the age-standardized rate of DALY was 347.67/100 000, and the age-standardized mortality rate was 14.03/100 000. Compared with 1990, the AAPC were −2.13%, −6.89% and −4.10% respectively. In contrast, during the COVID-19 pandemic, both showed a decreasing and then increasing trend, except for the age-standardized incidence rate, which showed a decreasing trend. Children under 5 years of age have experienced the greatest reduction in the burden of disease over the past decades, while the burden of disease has increased in absolute terms for the elderly over 70 years of age. Compared with 1990, the disease burden of LRI in China due to each pathogenic microorganism has decreased. And during 2019−2021, all pathogens showed an increasing trend, except for ASMR caused by influenza (APC=−55.21%) and respiratory syncytial virus (APC=−53.35%). In 2021, the primary attributable risk factors for LRI mortality in China shifted from household air pollution due to solid fuels, childhood underweight, and childhood stunting in 1990 to ambient particulate matter pollution, smoking, and secondhand smoke. ConclusionThe disease burden of LRIs in China showed an overall decreasing trend from 1990 to 2021, but with large variations between age groups and pathogens. During the two years following the outbreak of the COVID-19 pandemic, the incidence of LRI in China, along with the disease burden caused by influenza and respiratory syncytial virus, significantly declined. Over the past few decades, the attributable risk factors for mortality and DALYs have undergone substantial changes. To address this phenomenon, targeted measures should be implemented to reduce the burden of LRI on the population caused by air pollution and smoking.
ObjectiveTo collect and analyze the clinical data and quality of life of hemophilic children, understand the present condition of these patients in Sichuan Province, and analyze related influencing factors. MethodWe retrospectively analyzed the clinical data of hemophilic children treated in our hospital from January 1, 2008 to May 30, 2015. ResultsThere were 92 child patients from Sichuan Province with a median age of 9.6 years old (ranging from 3.6 to 18.0). There were 87 cases (94.6%) of hemophilia A and 5 (5.4%) of hemophilia B; the number of light cases was 4 (4.3%), of moderate cases was 67 (72.8%), and of severe cases was 21 (22.9%); eighteen (19.6) of the patients had family history. First bleeding episode occurred at a median age of 11 months (0-48 months). Mild bleeding occurred in 23 cases (25.0%), moderate bleeding in 31 cases (33.7%), and severe bleeding in 38 cases (41.3%). First bleeding site was mainly the mucous membrane of the skin, followed by the joint muscles. Fist joint bleeding occurred at a median age of 18 months (2-107 months). Forty-six patients (59.0%) had severe joint damage during the course of the disease. Intracranial hemorrhage occurred in 4 patients (4.3%), among whom 3 were cured and discharged from the hospital, and 1 had neurological sequelae. Median diagnostic age was 12 months (0-120 months). Sixty-two (67.4%) were diagnosed in a short period of time, 9 (9.8%) in a mediate period of time, and 21 (22.8%) in a long period of time. Forty (43.5%) of the patients had been given sufficient coagulation factors, while all the others had not received sufficient replacement therapy. Fifty-six (60.9%) children had received prophylactic treatment. First prophylaxis was administrated at a median age of 36 months (1-199 months), but 27 (48.2%) discontinued. The median score of the 29 retreated Disease Burden Scale was 22.7±11.6 (4-43), and among them, 11 (37.9%) could not care for themselves. Twenty-three participated in the assessment of social activity ability, among whom, 2 did not attend school, and 6 could not take part in the assessment because of school learning. Correlation analysis showed that there was no significant relationship between diagnostic timing and family history (P=0.795) or between diagnostic timing and areas they came from (P=0.495). However, significant association was found between diagnostic timing and the severity of first bleeding (r=0.392, P=0.035). Disease burden of family was significantly correlated with the number of target joints (r=0.370, P=0.048), and was not closely related with area, severity of bleeding, frequency of hemorrhage, medical insurance, or physical and social activities. ConclusionsThe general diagnosis and treatment condition of child hemophilia in Sichuan is relatively under-developed with a high prevalence of joint damage, poor quality of life, and high disease burden to the family. Improvement in the care of hemophilia children is urgently needed.
ObjectiveTo systematically review the disease burden of pneumoconiosis in Chinese population so as to provide references for health resources allocation and health policy making.MethodsDatabases including PubMed, EBSCO, Web of Science, CNKI, WanFang Data and VIP databases were searched for studies on investigation of the disease burden of pneumoconiosis in Chinese population from inception to 31st January, 2020. Two reviewers independently screened literature, exacted data, and assessed risk of bias of included studies. Systematic review was performed on data of pneumoconiosis associated population, mortality, and disease burden.ResultsA total of 26 studies were included. Qualitative analysis showed that the decrease of DALY and YLL of pneumoconiosis in China had been lower than that in globally, and the increase of YLD had been higher than that in globally in recent 10 years. 14 factors were included in the analysis of influencing factors on the financial burden or hospitalization expenses of pneumoconiosis patients; among them, the length of hospitalization, related complications, and pneumoconiosis stage were the most important indexes which had influence or difference on patients’ financial burden (or hospitalization expenses). The burden of pneumoconiosis in the Chinese population was primarily concentrated on males. Occupational diseases caused most of them, and middle-aged and older adults were the primary population for pneumoconiosis. However, young patients due to early-onset age, long course of disease and complications, and other factors resulting in a larger YLD phenomenon should also be considered.ConclusionsThe disease burden of pneumoconiosis patients in China is still heavy. It is recommended to continue to reduce the DALY of pneumoconiosis among the Chinese population as a long-term goal, and to strengthen control strategies to curb the early onset and death of pneumoconiosis.
Objective To analyze the characteristic and temporal trend in mortality and disease burden of Alzheimer’s disease (AD) and other forms of dementia in Guangzhou from 2008 to 2019, and estimate the disease burden attributable to smoking to provide evidence for promoting local health policy of prevention and intervention of dementia. Methods Based on the data of Guangzhou surveillance point of the National Mortality Surveillance System (NMSS), the crude mortality, standardized mortality, years of life lost (YLL) of AD and other dementia were calculated. The indirect method was used to estimate years lived with disability (YLD) and disability-adjusted life years (DALY).The distribution and changing trends of the index rates were compared from 2008 to 2019 using Joinpoint Regression Program. Based on the data of Guangzhou Chronic Disease and Risk Factors Monitoring System in 2013, the indexes of disease burden of AD and other forms of dementia attributable to smoking in 2018 was calculated. Results The standardized mortality rate, YLL rate, YLD rate and DALY rate of AD and other forms of dementia in Guangzhou increased from 0.45/100 000, 0.05‰, 0.02‰ and 0.07 ‰ in 2008 to 1.28/100 000, 0.15‰, 0.07‰ and 0.22‰ in 2019, respectively. The average annual changing trend was statistically significant (AAPC=11.30%, 13.09%, 13.09%, 13.09%, P<0.001）. In most years, the mortality and disease burden of women were higher than those of men, but men had higher growing trend than women in standardized mortality rate, YLL rate, YLD rate and DALY rate from 2008 to 2019, with a slower growing speed after the year 2012.The disease burden of dementia attributable to smoking in men was significantly higher than that in women. Conclusion The mortality and disease burden of AD and other forms of dementia in Guangzhou have dramatically increased over the past twelve years. Intervention against modifiable factors such as smoking, and prevention and screening for dementia in key populations should be strengthened. Support policies for dementia care management should be adopted to reduce the disease burden caused by premature death and disability.
Objective To investigate the association between costs of hospitalized patients with diabetes mellitus and their complications in the West China Hospital of Sichuan University, so as to provide baseline data for further research. Methods We extracted the hospitalization case data of hospitalized patients with diabetes mellitus who were discharged from the department of endocrinology and metabolism, or discharged after being transferred to other departments for treatment from January 2011 to December 2012, using the hospital information system (HIS) of the West China Hospital of Sichuan University. The data included baseline of hospital patients, discharge diagnosis, hospitalization costs, and if their medical insurance had been registered in hospital. Then, we classified the diseases according to ICD-10 based on discharge diagnosis, coped the data using Excel 2010 software, and conducted statistical analysis using SPSS 13.0. Results a) In 2011, acute and chronic diabetes complication in diabetes inpatients were 11.9% (166/1 396) and 67.1% (930/1 396), respectively. Most of them had peripheral neuropathy and peripheral vascular disease. b) The most frequently-occurred complications were hypertension, followed by dyslipidemia, and osteoporosis. c) The median hospital stay was 13 days (7 to 9 days), and the median total cost of hospital/person-time was 6 578.88 yuan (4 186.93 to 10 953.89 yuan). d) The total cost and duration of hospitalization increased along with the increasing number of the chronic complications of diabetes. e) The diabetic foot patients were 255 person-times, the median duration of hospitalization was 18 days (13 to 29 days), and the median total cost of hospital/person-time was 16 672.19 yuan (10 903.93 to 28 530.37 yuan). Diabetes patients with foot complication had higher total costs and longer duration of hospitalization than those without foot complication. Conclusion Diabetes mellitus is one of the most important diseases in the department of endocrinology and metabolism, which is heavy disease burden. The costs of hospitalization and chronic complications are closely associated. Among these complications, diabetic foot is the heaviest disease burden.
Objective To get known about the disease burden and quality of life (QOL) of rheumatoid arthritis (RA) in China by conducting a systematic review. Methods The observational studies about the disease burden and QOL of RA in China were systematically searched in the following databases: CNKI, CBM, VIP, WanFang Data, MEDLINE/Pub Med, EMbase, and Science Citation Index. The retrieval time was from January 1st, 1990 to July 31st, 2010. According to the inclusion and exclusion criteria, the literature was screened, the data were extracted, and the methodological quality of the included studies was assessed. The morbidity of RA was pooled by adopting generic inverse variance model, the meta-analyses on 8 dimensions of SF-36 life quality score (LQS) was conducted by suing RevMan5.0 software, the weighted mean difference (WMD) was regarded as the indicator of intervention effect, and the impact of studies’ quality on the results was assessed by sensitivity analysis. Results A total of 20 studies with medium quality in general were included. The morbidity of RA was 14.7/100 000. The disability adjusted of life years (DALYs) per capita were 4.92. If excluding the cost resulted from DALY, the overall economic cost was RMB 1 250.45 yuan per capita per year; While considering DALY, the cost was RMB 15 717.91 yuan per capita per year. The average cost of outpatient medications was RMB 8 018±17 238 yuan per capita per year. The weighted morbidity was 0.42% (95%CI 0.39% to 0.45%), and it was higher in female than male (Plt;0.05). There was no secular trend and difference between southern and northern (Pgt;0.05), but there were statistical significances in the WMD of 8 dimensions of SF-36 LQS. Sensitivity analyses revealed that the weighted pooled results were stable. Conclusion The epidemiological and economic burden of rheumatoid arthritis are heavier in China, which needs to be concerned by both government and society.
Objective To evaluate the disease burden of acne vulgaris in China from 1990 to 2019 and to provide references for the prevention and control of acne vulgaris in China. MethodsThe quantity of incidences/illnesses, age-standardized incidence/prevalence rates, disability-adjusted life years (DALYs), and DALY rate of acne vulgaris in China from 1990 to 2019 which were derived from the Global Burden of Disease (GBD) 2019 were evaluated. The epidemiological trends, age-birth-cohort trends, and the relationship between the incidence and sociodemographic index (SDI) were also analyzed. Results In 2019, the prevalence and incidence of acne vulgaris in China were higher than the global average. The quantity of patients was slightly higher in 2019 than that in 1990 (3.91%), and the prevalence, incidence, and DALY rate showed a continuous growth trend. The incidence of acne vulgaris peaked at 10 to 14 years old. Acne vulgaris mostly affected young males, and its prevalence peaked at approximately 15 to 19 years old. With these two age groups as the boundary, there was a trend of the prevalence of acne vulgaris increasing initially and then decreasing. Obvious gender differences existed for acne vulgaris diagnoses, and most of the above indicators were shown at a higher level in females than in males. The age period cohort analysis showed that the incidence rate of acne vulgaris in China from 1990 to 2019 was significantly different from the net drift, age effect, period effect and cohort effect. As the SDI value increased, the incidence of acne vulgaris showed a linear growth trend. Conclusions From 1990 to 2019, the burden of acne disease in China increases significantly.
Objective To analyze the trend of changes in the burden of liver cancer diseases attributed to alcohol consumption in China from 1990 to 2019. Methods Data on liver cancer burden attributed to drinking in China from 1990 to 2019 were obtained from the global burden of disease 2019. Joinpoint regression model was used to analyze the temporal trend of disease burden, and age-period-cohort model was used to evaluate age, period, and cohort effects. Results From 1990 to 2019, the standardized incidence rate of liver cancer attributable to drinking among the total population, men and women showed a downward trend. The AAPC was −2.52% (95%CI −2.83% to −2.21%), 3.26% (95%CI −3.62% to −2.89%) and −2.24% (95%CI −2.61% to −1.86%), respectively; The standardized mortality rates showed a decreasing trend, with AAPC values of −2.86% (95%CI −3.46% to −2.26%), −3.48% (95%CI −4.20% to −2.76%), and −2.67% (95%CI −2.99% to −2.34%), respectively; The standardized DALY rates showed a downward trend, with AAPC values of −3.09% (95%CI −3.65% to −2.53%), −2.92% (95%CI −3.25% to −2.58%), and −3.77 (95%CI −4.21% to −3.31%), respectively. The trend changes were statistically significant (P<0.05). From 1990 to 2019, the overall risk of liver cancer incidence and death attributed to drinking in China, both in males and females, showed a trend of first increasing and then decreasing with age; As the period increased, both the overall population and the male population showed a downward trend, followed by an upward trend, while the female population remained relatively stable; The lower the risk of liver cancer incidence and death attributed to drinking as the queue progressed. Conclusion The standardized incidence rate, mortality and DALY rates of liver cancer attributable to drinking in China are generally declining, we should strengthen health education and early diagnosis and treatment for both male and elderly people to reduce the burden of liver cancer.
ObjectivesTo systematically review the disease burden and epidemiological characteristics of tuberculosis in the Chinese population, and to provide reference for health resources allocation and health policy making.MethodsDatabases such as PubMed, EMbase, CNKI, VIP and WanFang Data were searched for studies investigating disease burden of tuberculosis in Chinese population from inception to August 1st, 2017. Two researchers independently screened literature, exacted data and assessed methodological quality of included studies. Statistical analysis was performed on data of tuberculosis associated population, mortality and disease burden.ResultsA total of 40 studies were included. The results of qualitative analysis showed that, since 1990, the prevalence of tuberculosis and its disease burden in China decreased year by year. However, the disease burden per patient and the total economic burden in China showed an increasing trend, and the economical disease burden increased 1.6 times from 1993 to 2003. The disease burden of men was higher than that of women, and it was higher in the countryside than in the city. In 2004, the ratio of YLL per thousand people in rural and urban areas was 2.18, and the ratio was 1.29 in 2014. Additionally, the disease burden decreased gradually in western, central and eastern regions. In 2014, compared with 2004, YLL decreased by 1.11, while the central and eastern regions were 0.48 and 0.25, respectively. The gap between the gender, the urban and rural areas and the regions was not as significant as in previous.ConclusionsThe disease burden of tuberculosis in China is seriously high and the tuberculosis prevention and control work should take into consideration the epidemiological characteristics of tuberculosis and the trends of the disease burden. It is necessary to rationally and effectively implement health intervention programs and allocate health resources based on different health demands in different regions and age groups to reduce the morbidity and mortality, and to pay more attention to drug-resistant tuberculosis. Besides, the emphasis of prevention should be placed on reducing disease burden in the elderly and strengthening prevention in the young population.
