Globally, harmful
alcohol use is a major modifiable contributor to the burden of disease.1 The typical age of
initiation of
alcohol use is around mid-adolescence and for a significant minority of
adolescents their
alcohol use will result in substantial harms, the most costly of which is
alcohol use disorder (AUD).2 Defined as a cluster of symptoms indicating continued
alcohol use despite significant problems, AUD is common and imposes a significant burden on the individual, their family and the wider society.
We included randomized controlled trials that evaluated parent training interventions; reported youth
initiation or
use of tobacco,
alcohol, or other illicit substances; and included
adolescents aged 10 to 19.
