2.3 billion worldwide suffer from dental caries in their permanent teeth, says report
According to The Lancet’s Global Burden of Disease (GBD) study 2015, 2.3 billion people worldwide suffer from dental caries (cavities) in their permanent teeth. Globally, chronic conditions such as headaches, dental caries, and hearing and vision loss each affect more than 1 in 10 people.
The GBD also says that life expectancy has risen globally but that 7 out of 10 deaths are now due to noncommunicable diseases (NCDs). And, while healthy life expectancy increased steadily in 191 of 195 countries (by 6.1 years) between 1990 and 2015, it did not rise as much as overall life expectancy (10.1 years). This means that people are living more years with illness and disability.
The GBD study 2015 further reports:
- Progress on reducing unsafe water and sanitation, but diet, obesity, and drug use are an increasing threat;
- More than 275,000 women died in pregnancy or childbirth in 2015, most from preventable causes
- Under-5 deaths have halved since 1990, but there is slower progress on reducing new-born deaths
The Lancet’s Global Burden of Disease study 2015 is the most up-to-date analysis on the state of the world’s health to equip governments and donors with evidence to identify national health challenges and priorities for intervention. It analyses 249 causes of death, 315 diseases and injuries, and 79 risk factors in 195 countries and territories between 1990 and 2015.
For the first time, GBD 2015 includes a measure of development (the Socio-Demographic Index, or SDI, which is based on income per capita, educational attainment and total fertility rate) in order to assess a country’s observed performance compared to their expected performance based on their stage of development.
