Abstract Background The aim is to reveal the trends in the incidence of Alzheimer’s disease (AD) and other dementias at the global, region, and national levels using data from 2017 Global Burden of Disease Study (GBD 2017). Methods We collected information on the number of incident cases and on the age-standardized incidence rate (ASIR) of AD and other dementias during 1990–2017 from the GBD 2017. We also analyzed differences in the incidence among different age groups. The association of ASIR with the development level was explored using Pearson correlation analysis. Results In 2017, the number of incident cases of AD and other dementias was 73.01 million (95% uncertainty interval [CI] = 65.16–81.33 million). This represented an increase of 113.17% from 1990, and an ASIR of 97.46 per 100,000 persons (95% CI = 86.80–108.89 per 100,000 persons). The ASIR was highest in countries in the high-middle sociodemographic index (SDI) quintile, and lowest in low-SDI-quintile countries. The number of incident cases increased from 1990 to 2017, whereas ASIR showed a slight downward trend in most countries. Japan had the highest ASIR in 2017 and showed the largest increase in ASIR over the preceding 28 years. The ASIR increased rapidly with age among those older than 70 years, and was significantly associated with the SDI (P < 0.0001, ρ = 0.68). Conclusion The incidence rate of AD and other dementias has declined in recent decades, but the incidence still remains high. The present findings should be useful for resource allocation and planning health services for AD and other dementias.

Abstract Pneumoconiosis has the potential to cause progressive and permanent physical disability. And continues to be one of major public health concern across the world. However, our literature searches identified a scarcity of data about global prevalence of pneumoconiosis. Accurate data on the incidence of pneumoconiosis is critical for health resource planning and health policy development. We therefore aimed to determine the pattern of pneumoconiosis incidence and temporal trends. Methods: Annual incident cases and age standardized incidence rates on pneumoconiosis etiology between 1990-2017 were collected from the Global Burden of Disease Study 2017. We calculate the average annual percentage changes of age standardized incidence rates by sex, region, and etiology to determine incidence trends of pneumoconiosis. Results: Globally, the number of pneumoconiosis cases increased 66.0% from 36,186 in 1990 to 60,055 in 2017. The overall age standardized incidence rate decreased by an average 0.6% (95% CI: 0.5%, 0.6%) per year in the same period. The age standardized incidence rate of silicosis, asbestosis, and other pneumoconiosis decreased between 1990 and 2017. The corresponding average annual percentage changes were -0.8%, -0.9%, and -0.5%, respectively. The age standardized incidence rate of asbestosis displayed an increasing trend. At the same time, we also found a significant negative association was found between average annual percentage changes and socio-demographic indexs when the socio-demographic index above 0.7. Conclusions: Pneumoconiosis remains a major occupational health illnesses in the world. Incidence patterns of pneumoconiosis caused by different etiologies were heterogeneous across regions and countries. We observed an unfavorable trend that asbestosis was predominant in countries with a high socio-demographic index, though we have attained great achievements in silicosis and coal workers’ pneumoconiosis prevention. The information in this study suggests that some countries should establish more targeted and specific strategies to forestall the increase in pneumoconiosis.

Background: Psoriasis is a common, chronic, inflammatory, debilitating, systemic disease with a great impact on healthcare systems worldwide. As targeted therapies have transformed the therapeutic landscape, updated estimates of the Global Burden of Disease (GBD) imposed by psoriasis are necessary in order to evaluate the effects of past health care policies and to orient and inform new national and international healthcare strategies.Methods: Data were extracted from the GBD 2019 study, which collates a systematic review of relevant scientific literature, national surveys, claims data, and primary care sources on the prevalence of psoriasis. Prevalence data were combined with disability weight (DW) to yield years lived with disability (YLDs). Measures of burden at global, regional, and national levels were generated for incidence, prevalence, and YLDs, due to psoriatic disease. All measures were reported as absolute numbers, percentages, and crude and age-adjusted rates per 100,000 persons. In addition, psoriasis burden was assessed by socio-demographic index (SDI).Findings: According to the GBD 2019 methodology, there were 4,622,594 (95% uncertainty interval or UI 4,458,904–4,780,771) incident cases of psoriasis worldwide in 2019. The age-standardized incidence rate in 2019 was 57.8 (95% UI 55.8–59.7) per 100,000 people. With respect to 1990, this corresponded to a decrease of 20.0% (95% UI −20.2 to −19.8). By sex, the age-standardized incidence rate was similar between men [57.8 (95% UI 55.8–59.8) per 100,000 people] and women [(57.8 (95% UI 55.8–59.7) per 100,000 people]. With respect to 1990, this corresponded to a decrease by 19.5% (95% UI −19.8 to −19.2) and by 20.4% (95% UI −20.7 to −20.2) for men and women, respectively. The age-standardized incidence rate per 100,000 persons was found to vary widely across geographic locations. Regionally, high-income countries and territories had the highest age-standardized incidence rate of psoriasis [112.6 (95% UI 108.9–116.1)], followed by high-middle SDI countries [69.4 (95% UI 67.1–71.9)], while low SDI countries reported the lowest rate [38.1 (95% UI 36.8–39.5)]. Similar trends were detected for prevalence and YLDs.Conclusion: In general, psoriasis burden is greatest in the age group of 60–69 years, with a relatively similar burden among men and women. The burden is disproportionately greater in high-income and high SDI index countries of North America and Europe. With advances in psoriasis therapeutics, objective evaluation of psoriasis disease burden is critical to track the progress at the population level.

Abstract Aim Schizophrenia is a serious health problem worldwide. This systematic analysis aims to quantify the burden of schizophrenia at the global, regional and national levels using the Global Burden of Disease Study 2017 (GBD 2017). Methods We collected detailed information on the number of incidence cases, disability-adjusted life years (DALYs) and age-standardised incidence rate (ASIR) and age-standardised rate of DALYs (ASDR) during 1990–2017 from GBD 2017. The estimated annual percentage changes (EAPCs) in the ASIR and in the ASDR were calculated to quantify the temporal trends in the ASIR and ASDR of schizophrenia. Results Globally there were 1.13 million (95% uncertainty interval [UI] = 1.00 to 1.28) incident schizophrenia cases and 12.66 million (95% UI = 9.48 to 15.56) DALYs due to schizophrenia in 2017. The global ASIR decreased slightly from 1990 to 2017 (EAPC = −0.124, 95% UI = −0.114 to −0.135), while the ASDR was stable. The number of incident cases, DALYs, ASIR and ASDR were higher for males than for females. The incident rate and DALYs rate were highest among those aged 20–29 and 30–54 years, respectively. ASIR and ASDR were highest in East Asia in 2017, at 19.66 (95% UI = 17.72 to 22.00) and 205.23 (95% UI = 153.13 to 253.34), respectively. In 2017, the ASIR was highest in countries with a high-moderate sociodemographic index (SDI) and the ASDR was highest in high-SDI countries. We also found that the EAPC in ASDR was negatively correlated with the ASDR in 1990 (P = 0.001, ρ = −0.23). Conclusion The global burden of schizophrenia remains large and continues to increase, thereby increasing the burden on health-care systems. The reported findings should be useful for resource allocation and health services planning for the increasing numbers of patients with schizophrenia in ageing societies.

Abstract Backgroud: Diabetes mellitus is a common chronic disease and a severe public health issue. The incidence trends for type 1 diabetes (TIDM) and type 2 diabetes (T2DM) have rarely been studied on a global scale. We aimed to determine the temporal and geographical trends of diabetes globally.Methods: Data on diabetes mellitus, including incidence, prevalence from 1990 to 2017 were obtained from the 2017 Global Burden of Disease study. We calculated the estimated annual percentage changes (EAPCs) in age-standardized incidence rate (ASR) of diabetes mellitus according to sex, region, and disease type.Results: The worldwide incident cases of diabetes mellitus has increased by 102.9% from 11,303,084 cases in 1990 to 22,935,630 cases in 2017 worldwide, while the ASR increased from 233.58/100,000 persons (95% UI, 218.95–249.37) to 284.56/100,000 persons (95% UI, 262.17–309.71) in this period [EAPC=0.87, 95% confidence interval (CI):0.79–0.96]. The global ASRs of T1DM and T2DM both demonstrated significant increase during 1990-2017, with EAPCs of 0.34 (95% CI:0.30–0.39) and 0.89 (95% CI:0.80–0.97), respectively. The ASR trends also varied considerably by regions and countries. The increase in ASR was greatest in high sociodemographic index regions (EAPC=1.05, 95% CI:0.92–1.17) and lowest in low-SDI regions (EAPC=0.79, 95% CI:0.71–0.88).Conclusions: Both the number of incident cases and ASR of diabetes mellitus increased significantly during 1990-2017 worldwide, but the temporal trends varied markedly across regions and countries.

Objective: This study examines trends in the mortality of Alzheimer’s disease and other dementias in China from 1990 to 2019. Methods: The data were drawn from the Global Burden of Disease Study 2019 (GBD 2019), and an age–period–cohort model was used for analysis. Results: The net drift was .152% (95% confidence interval [CI]: .069%, .235%) per year for men ( P < .05) and .024% (95% CI: −.078%, .126%) per year for women. The local drift values were below 0 in both genders for people aged 45–54 years ( P < .05), and above 0 for males aged 60–94 years and females aged 60–79 years ( P < .05). In the same birth cohort, the risk of mortality of Alzheimer's disease and other dementias exponentially increases with age for both genders. Conclusion: More rapid and effective efforts are needed to mitigate the substantial impact of Alzheimer's and other dementias on the health of China’s elderly.

BackgroundTo date, the burden of injury in Mexico has not been comprehensively assessed using recent advances in population health research, including those in the Global Burden of Disease Study 2017 (GBD 2017).MethodsWe used GBD 2017 for burden of unintentional injury estimates, including transport injuries, for Mexico and each state in Mexico from 1990 to 2017. We examined subnational variation, age patterns, sex differences and time trends for all injury burden metrics.ResultsUnintentional injury deaths in Mexico decreased from 45 363 deaths (44 662 to 46 038) in 1990 to 42 702 (41 439 to 43 745) in 2017, while age-standardised mortality rates decreased from 65.2 (64.4 to 66.1) in 1990 to 35.1 (34.1 to 36.0) per 100 000 in 2017. In terms of non-fatal outcomes, there were 3 120 211 (2 879 993 to 3 377 945) new injury cases in 1990, which increased to 5 234 214 (4 812 615 to 5 701 669) new cases of injury in 2017. We estimated 2 761 957 (2 676 267 to 2 859 777) disability-adjusted life years (DALYs) due to injuries in Mexico in 1990 compared with 2 376 952 (2 224 588 to 2 551 004) DALYs in 2017. We found subnational variation in health loss across Mexico’s states, including concentrated burden in Tabasco, Chihuahua and Zacatecas.ConclusionsIn Mexico, from 1990 to 2017, mortality due to unintentional injuries has decreased, while non-fatal incident cases have increased. However, unintentional injuries continue to cause considerable mortality and morbidity, with patterns that vary by state, age, sex and year. Future research should focus on targeted interventions to decrease injury burden in high-risk populations.

Abstract Background Depression is one of the major causes of disability worldwide. The objective of this study was to analyze the results of the Global Burden of Disease Study 2017 (GBD-2017) for depressive disorders in Brazil and its Federated Units (FUs) in 1990 and 2017. Methods We used GBD-2017 study methodology to evaluate the prevalence estimates, the disability-adjusted life-year (DALY) and the years lived with disability (YLDs) for depressive disorders, which include major depressive disorder and dysthymia. The YLD estimates and the position of these disorders in the DALY and YLD rankings were compared to those of seven other countries. The observed versus expected YLD, based on the sociodemographic index (SDI), were compared. Results In GBD-2017, the prevalence of depressive disorders in Brazil was 3.30% (95% uncertainty interval [UI]: 3.08 to 3.57), ranging from 3.79% (3.53 to 4.09) in Santa Catarina to 2.78% in Pará (2.56 to 3.03), with significant differences between the Federated Units. From 1990 to 2017, there was an increase in number of YLD (55.19%, 49.57 to 60.73), but a decrease in the age-standardized rates (-9.01%, -11.66 to -6.31). The highest proportion of YLD was observed in the age range of 15–64 years and among females. These disorders rank 4th and 13th as leading causes of YLD and DALY, respectively, in Brazil. In the other countries evaluated, the ranking of these disorders in the YLD classification was close to Brazil´s, while in the DALY classification, there was higher variability. All countries had YLD rates similar to the overall rate. The observed/expected YLD ratio ranged from 0.81 in Pará to 1.16 in Santa Catarina. Morbidity of depressive disorders was not associated with SDI. Conclusions Depressive disorders have been responsible for a high disability burden since 1990, especially in adult women living in the Southern region of the country. The number of people affected by these disorders in the country tends to increase, requiring more investment in mental health aimed at advancements and quality of services. The epidemiological studies of these disorders throughout the national territory can contribute to this planning and to making the Brazilian health system more equitable.
