A new report from the World Health Organization (WHO) highlights that 2.6 million deaths per year were attributable to alcohol consumption, accounting for 4.7% of all deaths, and 0.6 million deaths to psychoactive drug use. Notably, 2 million of alcohol and 0.4 million of drug-attributable deaths were among men.
WHO’s Global status report on alcohol and health and treatment of substance use disorders provides a comprehensive update based on 2019 data on the public health impact of alcohol and drug use and situation with alcohol consumption and treatment of substance use disorders worldwide. The report shows an estimated 400 million people lived with alcohol and drug use disorders globally. Of this, 209 million people lived with alcohol dependence.
The report highlights that despite some reduction in the alcohol-related death rates since 2010, the overall number of deaths due to alcohol consumption remains unacceptably high and amounts to 2.6 million in 2019, with the highest numbers in the European Region and the African region.
The death rates due to alcohol consumption per liter of alcohol consumed are highest in low-income countries and lowest in high-income countries.
Of all deaths attributable to alcohol in 2019, an estimated 1.6 million deaths were from noncommunicable diseases, including 474,000 deaths from cardiovascular diseases and 401,000 from cancer.
Some 724,000 deaths were due to injuries, such as those from traffic crashes, self-harm and interpersonal violence. Another 284,000 deaths were linked to communicable diseases. For example, alcohol consumption has been shown to increase the risk of HIV transmission resulting from an increased risk of unprotected sex and by increasing the risk of TB infection and mortality by suppressing a wide range of immune responses.
The highest proportion (13%) of alcohol-attributable deaths in 2019 were among young people aged 20–39 years.
Total alcohol per capita consumption in the world population decreased slightly from 5.7 liters in 2010 to 5.5 liters in 2019. The highest levels of per capita consumption in 2019 were observed in the WHO European Region (9.2 liters) and the Region of Americas (7.5 liters).
The level of alcohol consumption per capita among drinkers amounts on average to 27 grams of pure alcohol per day, roughly equivalent to two glasses of wine, two bottles of beer (33cl) or two servings of spirits (4cl). This level and frequency of drinking is associated with increased risks of numerous health conditions and associated mortality and disability.
In 2019, 38% of current drinkers had engaged in heavy episodic drinking, defined as consuming at least 60g of pure alcohol on one or more occasions in the preceding month – roughly equivalent to 4 or 5 glasses of wine, bottles of beer or servings of spirits. Continuous heavy drinking was highly prevalent among men.
Globally, 23.5% of all 15–19-year-olds were current drinkers. Rates of current drinking were highest among 15–19-year-olds in the European region (45.9%) followed by the Americas (43.9%).
Effective treatment options for substance use disorders exist, but treatment coverage remains incredibly low. The proportion of people in contact with substance use treatment services ranged from less than 1% to no more than 35% in 2019, in countries providing this data.
Most of the 145 countries that reported data did not have a specific budget line or data on governmental expenditures for treatment of substance use disorders. Although mutual help and peer support groups are useful resources for people with substance use disorders, almost half of responding countries reported that they do not offer such support groups for substance use disorders.
Stigma, discrimination and misconceptions about the efficacy of treatment contribute to these critical gaps in treatment provision, as well as the continued low prioritization of substance use disorders by health and development agencies.
