A government agency has voiced concern over advertising for alcohol in small grocery stores, convenience stores and petrol stations in the US and the possible impact on underage drinking and drunk driving among young people.

A study by the Center for Disease Control and Prevention (CDC) found point of sale alcohol advertising in 94% of 3,961 retailers surveyed in 329 US communities.

The CDC voiced concerns about the high prevalence of such advertising. It also observed that 44% of the outlets surveyed had ads placed at child-level height and less than half of the shops had corresponding responsible consumption messages.

“Public health agencies and policy makers should work with liquor control boards to reduce point-of-purchase marketing that could promote risky or underage drinking,” the CDC said.
