The number of US high school students that drink alcohol has dropped in the past nine years, a new survey shows.

In 2007, 45% of students admitted to having at least one alcoholic drink in the past 30 days compared to 33% in 2015, according to a Center for Disease Control poll. The survey, called the Youth Risk Behaviour Surveillance System (YRBSS), polls high-school students on potentially dangerous activities every other year.

The latest YRBSS report, released today, also shows that between 2013 and 2015 the prevalence of alcohol consumption among students fell from 35% to 33%.

Meanwhile, there was a significant drop in the number of students who had drunk alcohol before the age of 13, from 32% in 1999 to 17% in 2015. In comparison, the percentage fell from 33% to 32% between 1991 and 1999.

The results will come as good news to the US alcohol industry, which has argued that its responsible drinking message is lowering rates of teenage alcohol use.

In September last year, Anheuser-Busch InBev, Carlsberg and Heineken teamed up to launch a global effort to promote responsibility around beer consumption.

From 1991 to 2015, the YRBSS has collected data from more than 3.8m US high school students in more than 1,700 separate surveys.
