New Study Tells Us What We Already Know
"Importance:  Understanding the major health problems in the United States and how they are changing over time is critical for informing national health policy."
Really?  National health policy is what is going to unfrock the last forty years of disastrous health policy?  Not likely.

But if you are a public health policy monkey, these kinds of pronouncements probably sound oh so important.

Are they going to let insurance companies deny health coverage to folks booze too hard or become addicted in other ways?  Are they going to drop people with metabolic syndrome, sarcopenia and the other lifestyle diseases from the health care dole?

No, it sounds like they are going to continue to recommend that we all eat 100 pieces of fruit every 3 minutes, cause god knows that will cure anyone.

i don't know that we needed another expensive epidemiological study that tells us what we already know - folks are killing themselves with lifestyle choices that have been aided and abetted by USDA food pseudo science and a medical industry that makes money for keeping sick people alive.

I don't think the medical industry or the government is any closer to figuring out how to make our population kill itself with less vehemence.

CrossFit however is doing just that and we should be proud of it, and make it a centerpiece of each box. CrossFit teaches those willing to learn how to eat for health, and how to maintain an active, thriving life.  The best thing that could possibly come from this supposedly so important study is it may steer a few more folks to CrossFit boxes.


Understanding the major health problems in the United States and how they are changing over time is critical for informing national health policy.

Objectives  To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries.
Design  We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages.
Results  US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th.
Conclusions and Relevance  From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable. However, morbidity and chronic disability now account for nearly half of the US health burden, and improvements in population health in the United States have not kept pace with advances in population health in other wealthy nations.

The United States spends the most per capita on health care across all countries,12 lacks universal health coverage, and lags behind other high-income countries for life expectancy3 and many other health outcome measures.4 High costs with mediocre population health outcomes at the national level are compounded by marked disparities across communities, socioeconomic groups, and race and ethnicity groups.56 Although overall life expectancy has slowly risen, the increase has been slower than for many other high-income countries.3 In addition, in some US counties, life expectancy has decreased in the past 2 decades, particularly for women.78 Decades of health policy and legislative initiatives have been directed at these challenges; a recent example is the Patient Protection and Affordable Care Act, which is intended to address issues of access, efficiency, and quality of care and to bring greater emphasis to population health outcomes.9 There have also been calls for initiatives to address determinants of poor health outside the health sector including enhanced tobacco control initiatives,1012 the food supply,1315 physical environment,1617 and socioeconomic inequalities.18

With increasing focus on population health outcomes that can be achieved through better public health, multisectoral action, and medical care, it is critical to determine which diseases, injuries, and risk factors are related to the greatest losses of health and how these risk factors and health outcomes are changing over time. The Global Burden of Disease (GBD) framework19 provides a coherent set of concepts, definitions, and methods to do this. The GBD uses multiple metrics to quantify the relationship of diseases, injuries, and risk factors with health outcomes, each providing different perspectives. Burden of disease studies using earlier variants of this approach have been published for the United States for 19962022 and for Los Angeles County, California.23 In addition, 12 major risk factors have also been compared for 2005.24

In this report, we use the GBD Study 2010 to identify the leading diseases, injuries, and risk factors associated with the burden of disease in the United States, to determine how these health burdens have changed over the last 2 decades, and to compare the United States with other Organisation for Economic Co-operation and Development (OECD) countries.
