[Comment] Where is the accountability to adolescents?

The Lancet - Do, 17/09/2017 - 12:00
Accountability is a loaded concept. For many, the term itself has negative and punitive connotations. When it comes to accountability to adolescents—who number 1·2 billion today1—discourse is rare. Adolescents are the central promise for accelerated, lasting progress on the Global Strategy for Women's, Children's and Adolescents' Health2 and the Sustainable Development Goals (SDGs). But for adolescents, who lack power, vote, and influential voice, the notion of accountability to their health, development, and rights is fragile.

[Editorial] Life, death, and disability in 2016

The Lancet - Sa, 16/09/2017 - 00:00
In this week's issue of The Lancet, we publish the latest global, regional, and national estimates and analyses from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016), covering the period 1990 to 2016. The GBD is a herculean effort that annually tracks disease burden across countries, time, age, and sex. In 2016, there were an estimated 128·8 million livebirths and 54·7 million deaths. The good news is that globally, mortality rates have decreased across all age groups over the past five decades.

The Lancet - Sa, 16/09/2017 - 00:00
Globally, mortality rates have decreased across all age groups over the past five decades, with the largest improvements occurring among children younger than 5 years. However, at the national level, considerable heterogeneity remains in terms of both level and rate of changes in age-specific mortality; increases in mortality for certain age groups occurred in some locations. We found evidence that the absolute gap between countries in age-specific death rates has declined, although the relative gap for some age-sex groups increased.

[Global Health Metrics] Global, regional, and national age-sex specific mortality for 264 causes of death, 1980–2016: a systematic analysis for the Global Burden of Disease Study 2016

The Lancet - Sa, 16/09/2017 - 00:00
The past 37 years have featured declining rates of communicable, maternal, neonatal, and nutritional diseases across all quintiles of SDI, with faster than expected gains for many locations relative to their SDI. A global shift towards deaths at older ages suggests success in reducing many causes of early death. YLLs have increased globally for causes such as diabetes mellitus or some neoplasms, and in some locations for causes such as drug use disorders, and conflict and terrorism. Increasing levels of YLLs might reflect outcomes from conditions that required high levels of care but for which effective treatments remain elusive, potentially increasing costs to health systems.

[Global Health Metrics] Global, regional, and national incidence, prevalence, and years lived with disability for 328 diseases and injuries for 195 countries, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016

The Lancet - Sa, 16/09/2017 - 00:00
The decrease in death rates since 1990 for most causes has not been matched by a similar decline in age-standardised YLD rates. For many large causes, YLD rates have either been stagnant or have increased for some causes, such as diabetes. As populations are ageing, and the prevalence of disabling disease generally increases steeply with age, health systems will face increasing demand for services that are generally costlier than the interventions that have led to declines in mortality in childhood or for the major causes of mortality in adults.

[Global Health Metrics] Global, regional, and national disability-adjusted life-years (DALYs) for 333 diseases and injuries and healthy life expectancy (HALE) for 195 countries and territories, 1990–2016: a systematic analysis for the Global Burden of Dis

The Lancet - Sa, 16/09/2017 - 00:00
At a global level, DALYs and HALE continue to show improvements. At the same time, we observe that many populations are facing growing functional health loss. Rising SDI was associated with increases in cumulative years of life lived with disability and decreases in CMNN DALYs offset by increased NCD DALYs. Relative compression of morbidity highlights the importance of continued health interventions, which has changed in most locations in pace with the gross domestic product per person, education, and family planning.

[Global Health Metrics] Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016

The Lancet - Sa, 16/09/2017 - 00:00
Increasingly detailed understanding of the trends in risk exposure and the RRs for each risk-outcome pair provide insights into both the magnitude of health loss attributable to risks and how modification of risk exposure has contributed to health trends. Metabolic risks warrant particular policy attention, due to their large contribution to global disease burden, increasing trends, and variable patterns across countries at the same level of development. GBD 2016 findings show that, while it has huge potential to improve health, risk modification has played a relatively small part in the past decade.

[Viewpoint] Measuring global health: motivation and evolution of the Global Burden of Disease Study

The Lancet - Sa, 16/09/2017 - 00:00
People everywhere, but particularly those charged with improving the health of populations, want to know whether human beings are living longer and getting healthier. There is an inherent fascination with quantification of levels and patterns of disease, the emergence of new threats to health, and the comparative importance of various risk factors for the health of populations. Before the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) was initiated, no comprehensive assessments of human health were done.
