The intersection of risk, mortality, and morbidity in particular geographic areas needs to be further explored at the state level. The probability of death among adults aged 20 to 55 years declined in 31 states and Washington, DC from to In , Hawaii had the highest life expectancy at birth Minnesota had the highest HALE at birth The leading causes of DALYs in the United States for and were ischemic heart disease and lung cancer, while the third leading cause in was low back pain, and the third leading cause in was chronic obstructive pulmonary disease.
Opioid use disorders moved from the 11th leading cause of DALYs in to the 7th leading cause in , representing a Across all US states, the top risk factors in terms of attributable DALYs were due to 1 of the 3 following causes: tobacco consumption 32 states , high BMI 10 states , or alcohol and drug use 8 states. Specific diseases and risk factors, such as drug use disorders, high BMI, poor diet, high fasting plasma glucose level, and alcohol use disorders are increasing and warrant increased attention.
These data can be used to inform national health priorities for research, clinical care, and policy. Recent attention has focused on increased mortality in some age groups and a decline in life expectancy.
Several studies have shown large variations in risk factors by state and county, and these variations have contributed to differences in health outcomes. GBD is now conducted on an annual cycle, with GBD providing updated estimates of mortality, morbidity, and risk factors in locations, including the United States, from to The findings of GBD indicate that while the United States overall is experiencing improvements in health outcomes, the patterns of health burden at the state level vary across geography.
Routinely monitoring the trend of burden of disease at the state level is essential given the vital role of states in many aspects of health and social policy 19 —from the Medicaid program to regulation of private insurers 20 and considering that individual states also experience different economic circumstances.
The current study uses GBD to report the change in burden of disease, including injuries and risk factors at the state level, from to The numbers reported in the previous round of GBD are not identical to those of the current round GBD for 2 main reasons. Second, the new analysis at the state level changes some of the estimation slightly when aggregated to the national level.
GBD provides a new time series. GBD provides a comprehensive assessment of all-cause mortality and estimates for death due to causes in countries and territories from to , as well as causes of DALYs Appendix Table 2 in Supplement 2. Level 1 has 3 causes: communicable, maternal, neonatal, and nutritional disorders; noncommunicable diseases; and injuries. Level 2 has 21 causes. Levels 3 and 4 consist of more disaggregated causes. GBD documented each step of the estimation processes, as well as data sources, in accordance with the Guidelines for Accurate and Transparent Health Estimates Reporting.
Disability-adjusted life-years: a summary metric of population health. The goal is for individuals to live the standard life expectancy in full health. Healthy life expectancy: the number of years that a person at a given age can expect to live in good health, taking into account mortality and disability.
Summary Exposure Value: the relative risk—weighted prevalence of exposure developed for Global Burden of Diseases Study Years lived with disability: computed as the prevalence of different disease sequelae and injury sequelae multiplied by disability weights for that sequela. Disability weights are selected on the basis of surveys of the general population about the health loss associated with the health state related to the disease sequela.
Years of life lost due to premature mortality: computed by multiplying the number of deaths at each age by a standard life expectancy at that age. The standard selected represents the normative goal for survival and has been computed based on the lowest recorded death rates across countries in Hospital inpatient data were extracted and used for this analysis.
Moreover, outpatient encounter data were available for the United States through aggregate data derived from a database of claims information for US private and public insurance schemes for the years , , and GBD methodology applied several correction factors to account for bias in health service encounter data from these claims that were available as aggregated by International Classification of Diseases ICD code and by primary diagnosis only. First, for chronic disorders, the study estimated the ratio between prevalence from primary diagnoses and prevalence from all diagnoses associated with a claim.
Second, the claims data were used to generate the mean number of outpatient visits per disorder. Similarly, the study generated per-person discharge rates from hospital inpatient data in the United States.
All-cause mortality was estimated by age, sex, geography, and year using 6 modeling approaches to assess cause-specific mortality; the Cause of Death Ensemble Model was used to generate estimates for the vast majority of causes. The cause list developed for the GBD 13 is arranged hierarchically in 4 levels. Within each level, the cause list is designed such that all deaths are assigned exactly 1 cause. Previous studies have documented the existence of insufficiently specific or implausible causes of death used in death registration data that may lead to misleading geographic and temporal patterns.
More detail on each of these methods is provided in Section 2 of Supplement 1. Based on standard GBD methods, YLLs were computed by multiplying the number of deaths from each cause in each age group by the reference life expectancy at the mean of age of death among those who died in the age group.
The standard is meant to represent the mortality experience of a population with minimal excess mortality using the lowest observed age-specific mortality rates in among all countries with a population greater than 5 million. This standard does not vary with time because for most populations, the number of YLLs once normalized for population size is larger in earlier years than in later years due to improving survival rather than an artifact of the standard used.
In this study, incidence and prevalence of diseases by age, sex, cause, year, and geography were estimated using a wide range of updated and standardized analytical procedures. Data sources used for quantifying nonfatal outcomes are available online in the GBD results tool 41 and in Section 3 of Supplement 1. Prevalence of each sequela was multiplied by the disability weight for the corresponding health state to calculate YLDs for the sequela.
Details on disability weights for GBD , including data collection and disability weight construction, are described elsewhere. GBD used the comparative risk assessment framework to estimate attributable deaths, DALYs, and trends in exposure by age group, sex, year, and geography for risks from to GBD has 84 behavioral, environmental and occupational, and metabolic risks or clusters of risks Section 5 in Supplement 1.
Risk-outcome pairs were included in the GBD study if they met World Cancer Research Fund criteria for convincing or probable evidence. Relative risk RR estimates were extracted from published and unpublished randomized clinical trials, cohorts, and pooled cohorts. Risk exposures were estimated based on published studies, household surveys, US Census data, satellite data, and other sources.
Two modeling approaches, a Bayesian meta-regression model and a spatiotemporal Gaussian process regression model, were developed for the GBD study and used to pool data from different sources, adjust for bias in the data, and incorporate potential covariates.
GBD used the counterfactual scenario of theoretical minimum risk exposure level ie, the level for a given risk exposure that could minimize risk at the population level to attribute burden. A summary exposure value was developed for GBD as the RR-weighted prevalence of exposure range, 0 [no excess risk exists in a population] to 1 [population is at the highest risk].
This quantity is estimated for each age group, sex, geography, and year. In the case of dichotomous exposure, summary exposure value is equal to prevalence. For continuous risks, summary exposure value is defined as follows:. To calculate risk-attributable fractions of disease burden by cause, the effects of risk exposure levels were modeled, RRs associated with risk exposure and specific health outcomes were documented, and counterfactual levels of risk exposure on estimates of national and state-level deaths, YLLs, YLDs, and DALYs were computed.
Detailed descriptions of the GBD methods for risk factor assessment and attribution are published elsewhere Section 5 in Supplement 1. The probability of death was calculated for 3 summary age intervals and the cause-specific contributions to each of these summary indicators for ages 0 to 20, 20 to 55, and 55 to 90 years. These age groups were chosen to reflect variations in trends and burden for adolescents, young adults, and older people.
For each probability of death, the multiple decrement life-table method was used to compute the probability of death from each cause and the overall contribution of each cause of death to the summary probability of death. Although discrete age categories from life table calculations were used, the age categories slightly overlap for calculations of probability of death ages 20 years and 55 years; see Section 6 in Supplement 1.
To decompose the key drivers of life loss, the probability of death was determined and examined in parallel to the cause fractions for that same age group. Additional information on the decomposition of changes in the probability of death, including the formulas used, is available in the online methods section Supplement 1.
GBD created a summary indicator that combines measures of income per capita, educational attainment for age 15 years or older, and total fertility rates. The current sociodemographic index SDI was used to compare observed patterns of health loss to expected patterns for countries or locations with similar SDI scores. The SDI was computed similarly to the computation of the human development index to improve interpretability.
Each component of the SDI was weighted equally and rescaled range, 0 [lowest observed value during ] to 1 [highest observed value during ]. Table 1 lists the 25 leading causes of death and premature mortality from to Ischemic heart disease IHD ; cancer of the trachea, bronchus, and lung; chronic obstructive pulmonary disease; Alzheimer disease and other dementias; and cancer of the colon and rectum were the 5 leading causes of death.
Despite a There was an increase in age-standardized mortality and in age-standardized YLLs from for chronic obstructive pulmonary disease There was a decrease in age-standardized mortality and in age-standardized YLLs for colon and rectal cancer Deaths from endocrine, metabolic, blood, and immune disorders increased by
The problems of the haves differ substantially from those of the have-nots. Individuals in developing societies have to fight mainly against infectious and communicable diseases, while in the developed world the battles are mainly against lifestyle diseases. Yet, at a very fundamental level, the problems are the same-the fight is against distress, disability, and premature death; against human exploitation and for human development and self-actualisation; against the callousness to critical concerns in regimes and scientific power centres. While there has been great progress in the treatment of individual diseases, human pathology continues to increase. Sicknesses are not decreasing in number, they are only changing in type.
However, developing countries are more exposed and more vulnerable due to a multitude of factors, including geographic, demographic and socio-economic factors. Noncommunicable diseases like cardio-vascular diseases, cancer, diabetes, chronic obstructive pulmonary disease and mental disorders are affecting developing countries with an increasing trend. Other diseases like the so-called neglected diseases are exclusively afflicting developing countries. Low-income countries are particularly affected by lymphatic filariasis, leishmaniasis, schistosomiasis, Buruli ulcer, cholera, cysticercosis, dracunculiasis, foodborne trematode infections, hydatidosis, soil-transmitted helminthiasis ascariasis, trichuriasis, hookworm diseases , trachoma, sleeping sickness, onchocerciasis, Chagas disease, dengue and others. More generally, communicable and noncommunicable diseases are impeding human development in developing countries by their negative impact on education, income and life expectancy and other health indicators.
Burden of Disease—Implications for Future Research. One overall challenge for public health and medicine in the future is to allocate available resources effectively to reduce major causes of disease burden globally and to decrease health disparities between poor and affluent populations. The major risk factors for death and disability worldwide are malnutrition; poor water supply, sanitation, and personal and domestic hygiene; unsafe sexual behavior; tobacco use; alcohol use; occupational hazards; hypertension; physical inactivity; illicit drugs; and air pollution. The challenge for research in the 21st century is to maintain and improve life expectancy and the quality of life that was achieved for most of the world's population during the 20th century. Gains in life expectancy worldwide were greater during the last century than at any other time in recorded human history. The rate of increase in life expectancies in the first half of the century was greatest in the United States, Europe, Australia, and New Zealand. For example, in the United States, life expectancy was 49 years in and 66 years by
Comprehensive Assessment of Mortality and Disability from Diseases,. Injuries, and Disease burden is, in effect, the gap between a population's actual health status Is a year of healthy life now worth more to society than a year of healthy.
A straightforward way to assess the health status of a population is to focus on mortality — or concepts like child mortality or life expectancy , which are based on mortality estimates. A focus on mortality, however, does not take into account that the burden of diseases is not only that they kill people, but that they cause suffering to people who live with them. Assessing health outcomes by both mortality and morbidity the prevalent diseases provides a more encompassing view on health outcomes.
The disability-adjusted life year DALY is a measure of overall disease burden , expressed as the number of years lost due to ill-health, disability or early death. It was developed in the s as a way of comparing the overall health and life expectancy of different countries. It not only includes the potential years of life lost due to premature death , but also includes equivalent years of 'healthy' life lost by virtue of being in states of poor health or disability. In so doing, mortality and morbidity are combined into a single, common metric. The disability-adjusted life year is a societal measure of the disease or disability burden in populations. DALYs are calculated by combining measures of life expectancy as well as the adjusted quality of life during a burdensome disease or disability for a population. Also, QALYs tend to be an individual measure, and not a societal measure.
Each year, the American Heart Association, in conjunction with the Centers for Disease Control and Prevention, National Institutes of Health and other government agencies, compiles up-to-date statistics on heart disease, stroke and other vascular diseases in the Heart Disease and Stroke Statistical Update. This is a valuable resource for researchers, clinicians, healthcare policy makers, media professionals, the public and others who seek the best national data available on disease morbidity, mortality and risks; quality of care; medical procedures and operations; and costs associated with the management of these diseases.
The COVID pandemic has had far-reaching consequences beyond the spread of the disease itself and efforts to quarantine it, including political, cultural, and social implications. A number of provincial-level administrators of the Communist Party of China CPC were dismissed over their handling of the quarantine efforts in Central China , a sign of discontent with the political establishment's response to the outbreak in those regions. Some experts believe this is likely in a move to protect Communist Party general secretary Xi Jinping from people's anger over the coronavirus pandemic.
