In rainfall-runoff modelling, a monthly timescale and an annual one are sufficient for the management of deductions. However, to simulate the flow at a large time-step (annual), we generally precede the use of a model working for a finer time-step (daily) while aggregating the desired outputs. The finest time-steps are considered, apriori, as the most performant. By passing from one time-step to another, and in order to work in the desired time-step (annual) and calculate the potential gains or loss, this article proposed a comparative study between the aggregation method of outputs of a modal working at a finer time step, and a method in which we use a conceived model from the beginning. To ensure this comparative and empirical approach, the choice has been focused on (GRs) models to a daily time-step (GR4J), monthly time step (GR2M) and annual time step (GR1A). The modelling platform used is the same for all three models taking into account the specificities of each one: the same data sample, the same optimization method, and the same function criterion are used during the construction of these models. Due to the moving between these time steps, results show that the best way to simulate the annual flow is to use an appropriate and designed modal initially conceived to this time step. Indeed, this simulation seems to be less effective when using a model at a finer time-step (daily). 展开更多

Based on the calculation method of information gain in the stochastic process presented by Vere-Jones, the rela tion between information gain and probability gain is studied, which is very common in earthquake prediction, and the yearly probability gain for seismic statistical model is proposed. The method is applied to the non stationary Poisson model with whole-process exponential increase and stress release model. In addition, the prediction method of stress release model is obtained based on the inverse function simulation method of stochastic variable. 展开更多

Background:China accounts for one-quarter of the world’s diabetes population,with significant subnational disparities.However,none of the available data have provided comprehensive estimates and projections at both regional and national levels in diabetes prevention and management.This study aimed to explore the temporal trends and geographical variations in the prevalence and non-fatal burden of diabetes by age and sex across China from 2005 to 2023,and to forecast diabetes prevalence through 2050.Methods:We conducted a population-based study based on the nationally representative surveys,and literature reviews.Using the DisMod-MR model and Chinese-specific disease disability weights,we estimated the non-fatal burdens of diabetes,including prevalence and years lived with disability(YLDs),across sexes,age groups,and locations.The temporal trend change was measured as the average annual percent change.The effect of the human development index on burdens was assessed by applying Spearman’s rank correlation analysis.We further projected diabetes prevalence to 2050 under 2 scenarios,the natural trend and the effective intervention on body mass index(BMI).Results:In 2023,an estimated 233 million individuals in China were living with diabetes.Compared to 2005,the agestandardized rate(ASR)of prevalence has increased by nearly 50%,from 7.53%(95%CI 7.00-8.10)to 13.7%(95%CI 12.6-14.8)in 2023.The ASR of YLDs was estimated at 19.1 per 1000 population(95%CI 18.6-19.5)in 2023,compared to 10.5 per 1000 population in 2005.The ASR of prevalence and YLDs was consistently higher in males than in females.The provinces with the highest diabetes prevalence and disease burden were Beijing,Tianjin,and Shanghai.Our forecast results suggest that if existing trends continue,the prevalence of obesity will reach 29.1%(95%CI 22.2-38.2)nationally by 2050,with some provinces in the northern region observing a prevalence of over 40%.Conversely,if effective obesity interventions were implemented,the growth in diabetes prevalence could potentially be suppressed by nearly 50%.Conclusions:The health burden and economic cost associated with diabetes are profound.There is an urgent need to scale up preventive efforts and improve population awareness to enhance disease management and achieve optimal treatment outcomes. 展开更多

BACKGROUND The burden of mental disorders(MD)in the Western Pacific Region(WPR)re-mains a critical public health concern,with substantial variations across demogra-phics and countries.AIM To analyze the burden of MD in the WPR from 1990 to 2021,along with associated risk factors,to reveal changing trends and emerging challenges.METHODS We used data from the Global Burden of Disease 2021,analyzing prevalence,incidence,and disability-adjusted life years(DALYs)of MD from 1990 to 2021.Statistical methods included age-standardisation and uncertainty analysis to address variations in population structure and data completeness.RESULTS Between 1990 and 2021,the prevalence of MD rose from 174.40 million cases[95%uncertainty interval(UI):160.17-189.84]to 234.90 million cases(95%UI:219.04-252.50),with corresponding DALYs increasing from 22.8 million(95%UI:17.22-28.79)to 32.07 million(95%UI:24.50-40.68).During this period,the burden of MD shifted towards older age groups.Depressive and anxiety disorders were predominant,with females showing higher DALYs for depressive and anxiety disorders,and males more affected by conduct disorders,attention-deficit hyperactivity disorder,and autism spectrum disorders.Australia,New Zealand,and Malaysia reported the highest burdens,whereas Vietnam,China,and Brunei Darussalam reported the lowest.Additionally,childhood sexual abuse and bullying,and intimate partner violence emerged as significant risk factors.CONCLUSION This study highlights the significant burden of MD in the WPR,with variations by age,gender,and nation.The coronavirus disease 2019 pandemic has exacerbated the situation,emphasizing the need for a coordinated response. 展开更多

In 1993,the World Bank released a global report on the efficacy of health promotion,introducing the disability-adjusted life years(DALY)as a novel indicator.The DALY,a composite metric incorporating temporal and qualitative data,is grounded in preferences regarding disability status.This review delineates the algorithm used to calculate the value of the proposed DALY synthetic indicator and elucidates key methodological challenges associated with its application.In contrast to the quality-adjusted life years approach,derived from multi-attribute utility theory,the DALY stands as an independent synthetic indicator that adopts the assumptions of the Time Trade Off utility technique to define Disability Weights.Claiming to rely on no mathematical or economic theory,DALY users appear to have exempted themselves from verifying whether this indicator meets the classical properties required of all indicators,notably content validity,reliability,specificity,and sensitivity.The DALY concept emerged primarily to facilitate comparisons of the health impacts of various diseases globally within the framework of the Global Burden of Disease initiative,leading to numerous publications in international literature.Despite widespread adoption,the DALY synthetic indicator has prompted significant methodological concerns since its inception,manifesting in inconsistent and non-reproducible results.Given the substantial diffusion of the DALY indicator and its critical role in health impact assessments,a reassessment is warranted.This reconsideration is imperative for enhancing the robustness and reliability of public health decisionmaking processes. 展开更多

BACKGROUND Mental disorders have become a major contributor to the Global Burden of Disease(GBD),a situation that has worsened with the onset of the coronavirus disease 2019(COVID-19)pandemic.Updated data on their impact and a clear understanding of long-term trends are essential for global and national health authorities to implement effective prevention and intervention strategies for mental well-being.AIM To generate insights that will enhance global awareness of the burden of mental disorders and support the development of targeted,region-specific prevention and intervention strategies tailored to current global and local health challenges.METHODS We extracted data on incidence,disability-adjusted life years(DALYs),agestandardized incidence rate(ASIR),and age-standardized DALY rate(ASDR)for 12 categories of mental disorders from 1990 to 2021 across 204 countries and territories grouped into 21 regions.Trends in ASIR and ASDR were also analyzed during the COVID-19 period(2019-2021).RESULTS From 1990 to 2021,global ASIR rose by 15.23%(12.97%to 17.60%),while ASDR increased by 73.52%(70.24%to 76.71%).All 21 GBD regions saw a rise in cases and DALYs.In 2021,Central sub-Saharan Africa had the highest ASIR(8706.11),and East Asia reported the lowest(3340.99).Australasia recorded the highest ASDR(2787.87).On the national level,Greenland,Greece,United States,and Australia had the greatest ASDR values.During the pandemic years,ASIR and ASDR rose across all five socio-demographic index levels and GBD regions,with the exception of East Asia,where rates remained stable.Females experienced a higher ASDR than males in 2021.Major depressive disorder(557.87)and anxiety disorders(524.33)were the most burdensome among the 12 types,with depressive disorders ranking first in 13 out of the 21 regions.CONCLUSION The GBD study 2021 results highlight a continued and worsening global burden of mental disorders,further intensified by the COVID-19 crisis.This underscores the urgent need to reinforce mental health care systems.Special attention should be directed toward high-middle socio-demographic index areas and female populations.Expanding access to mental health services,enhancing public awareness,and delivering targeted interventions are essential to lessen the growing impact of mental disorders. 展开更多
