International collaborative Global Burden of Disease enterprise offers insights into progress and challenges in achieving the UN’s Sustainable Development Goals
SEATTLE – Expanded health coverage, greater access to family planning, and fewer deaths of newborns and children under the age of 5 are among several health improvements contributing to progress toward achieving the United Nations’ Sustainable Development Goals (SDGs), according to a new scientific study.
However, childhood obesity, alcohol consumption, and death caused by violence continue to be significant hurdles many nations are facing as the world reaches the end of the first year of the 15-year goals.
The study by the international Global Burden of Disease Study (GBD) collaboration, published today in The Lancet, analyzed each country’s progress toward achieving health-related SDG targets by creating an overall SDG Index score. Countries were then ranked by their scores to show which nations are closest to achieving the targets.
A nation’s SDG index score is based on a scale of zero to 100. As a result, Iceland tops the list with a score of 85. The lowest-scoring nation was the Central African Republic, at 20. The United States has a score of 75, just behind Slovenia, Greece, and Japan, all at 76.
To see how nations compare to others, countries were divided into five categories, based on a combination of education, fertility, and income per capita. This new categorization goes beyond the historical “developed” vs. “developing” or economic divisions based solely on income.
The study’s top findings include:
- There has been significant improvement in child and maternal survival over the past 25 years.
- More skilled doctors, nurses, and midwives are assisting with child deliveries.
- Many countries have increased access to essential health services, especially antiretroviral therapies to treat HIV and the availability of malaria nets.
- Fewer people are dying from unsafe drinking water and poor sanitation, as well as air pollution.
- Countries with higher socio-demographic standing saw faster declines in deaths from chronic disease, road injuries, and violence.
- Countries in the lower socio-demographic groups saw faster declines in childhood wasting and stunting.
The researchers note that these gains will need to be sustained, and in many cases accelerated, to achieve the ambitious SDG targets. The findings also highlight the importance of income, education, and birth rates as drivers of health improvement, and that investments in those areas alone will not be sufficient.
“We know that international targets can motivate countries and motivate donors,” said IHME Director Dr. Christopher J.L. Murray. “The international Global Burden of Disease collaboration is committed to providing an independent assessment of progress toward the Sustainable Development Goals.”
Kenya’s SDG Index score increased between 2000 and 2015, from 33 to 40. The prevalence of childhood stunting there dropped as a percentage of the population from 39% in 2000 to 26% in 2015. One potential driver of the decrease in stunting in Kenya is the concurrent increase in access to health services. In 2015, 70% of Kenyans who needed an essential health intervention received it, in contrast to just 32% in 2000.
In Ethiopia, the prevalence of childhood stunting dropped from 57% in 2000 to 41% in 2015. These improvements occurred at a time of increased funding for child and newborn health services in the country, growing from $13 million in 2000 to $190 million in 2013, a 14-fold increase.
Brazil has made great progress in reducing child deaths, eliminating nearly 50% of its under-age-5 child deaths in the past 15 years. In 2000, 31 children died for every 1,000 live births in Brazil. That number fell to 17 in 2015.
The proportion of countries that have accomplished individual targets varies greatly. For example, more than 60% of the 188 countries studied shows maternal mortality rates below 70 deaths per 100,000 live births, effectively hitting the SDG target. In contrast, no nation has reached the objective to end childhood overweight, or to fully eliminate infectious diseases like HIV or tuberculosis.
“We have concrete examples of countries making important progress on a range of health-related SDG indicators,” said Dr. Stephen S. Lim, Professor of Global Health at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, and lead author of study. “We now need to look to those countries that have seen strong progress to find out what they are doing right and how it can be applied more broadly.”
The GBD is the largest and most comprehensive epidemiological effort to quantify health loss across places and over time. The GBD enterprise – now consisting of more than 1,800 researchers and policymakers in nearly 130 nations and territories – is coordinated by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington.

Established in 2007, the Institute for Health Metrics and Evaluation (IHME) is an independent global health research center at the University of Washington in Seattle that provides rigorous and comparable measurement of the world’s most important health problems and evaluates strategies to address them. IHME makes this information available so that policymakers, donors, practitioners, researchers, and local and global decision-makers have the evidence they need to make informed decisions about how to allocate resources to best improve population health.

NOTE ON THE STUDY: IHME created the “health-related SDG index” by combining results for 33 health-related SDG indicators and giving a single value, on a scale of zero to 100, for each country. The index allows measurement of how much a country has improved overall from 2000 to 2015. Each indicator is individually scored as well, and a composite (a geometric mean) of these 33 scores translates into the health-related SDG index score. The change in this score from year to year shows whether a country is progressing toward the target. Countries showing tremendous improvements should be looked to as examples of change and progress.
